Abdominal bloating in children: association with functional gastrointestinal diseases and adverse life events.
(The Korean Society of Neurogastroenterology and Motility, 2013) Rajindrajith, S.; Devanarayana, N.M.
BACKGROUND/AIMS: Abdominal bloating is a common symptom among children with functional gastrointestinal diseases (FGDs). It can lead to significant distress among affected children. However, its epidemiology, risk factors and clinical characteristics have not been described in paediatric population. We aimed to study die epidemiology and risk factors of abdominal bloating, and associated FGDs in Sri Lankan children. METHODS: A cross-sectional, island-wide survey was conducted in Sri Lankan children aged 10-16 years. Four provinces (out of 9) of the country were randomly selected and 2 schools were randomly selected from each of the provinces. From each school, 12 classes from academic years (grades) 6 to 11 (2 from each academic year) were randomly selected and all children in these classes were included in the study. The Rome III questionnaire for paediatric FGDs (self-report form) was used for data collection. FGDs were diagnosed using Rome III criteria. Abdominal bloating was considered to be present if die child indicated as having abdominal bloating at least 25% of the time during the past 2 months. RESULTS: A total of 1972 children and adolescents (54.8% boys, mean age 13.4 years, SD 1.8 years) were included in the analysis. One hundred and ninety-four (9.8%) children had abdominal bloating. Of them, 52.6% had aerophagia, 15.4% had irritable bowel syndrome, 9.7% had constipation, 6-7% had rumination syndrome, and 5.6% had functional abdominal pain. Bloating was significantly common among children exposed to emotional stress and adverse life events (P < 0.0001). Intestinal related symptoms and extra intestinal symptoms that were significantly associated with bloating include abdominal pain, nausea, pallor, photophobia and headache (P < 0.05). CONCLUSIONS: Bloating is a common symptom of children and often associated with a range of FGDs. Children who faced adverse life events and stress, have a higher tendency to develop bloating. Bloating coexist with several other intestinal related and extra intestinal symptoms.
Abdominal migraine in children: association between gastric motility parameters and clinical characteristics
(BioMed Central, 2016) Devanarayana, N.M.; Rajindrajith, S.; Benninga, M.A.
BACKGROUND: Approximately 0.2-1 % of children suffers from abdominal migraine (AM). Pathophysiology of AM has not been adequately studied. This study evaluated gastric motility in children with AM. METHODS: Seventeen children (6 boys), within an age range of 4-15 years, referred to a tertiary care paediatric unit, North Colombo Teaching Hospital Ragama, Sri Lanka, from 2007 to 2012, were screened. Those fulfilling Rome III criteria for AM were recruited after obtaining parental consent. None had clinical or laboratory evidence of organic disorders. Twenty healthy children (8 boys), with an age range of 4-14 years, were recruited as controls. Liquid gastric emptying rate (GE) and antral motility parameters were assessed using an ultrasound method. RESULTS: Average GE (41.6 % vs. 66.2 %, in controls), amplitude of antral contractions (A) (57.9 % vs. 89.0 %) and antral motility index (MI) (5.0 vs. 8.3) were lower and fasting antral area (1.8 cm(2) vs. 0.6 cm(2)) was higher in children with AM (p < 0.01). No significant difference in the frequency of antral contractions (F) (8.8/3 min vs. 9.3/3 min, p = 0.08) was found between the two groups. Scores obtained for severity of abdominal pain had a negative correlation with A (r = -0.55, p = 0.03). Average duration of abdominal pain episodes correlated with GE (r = -0.58, p = 0.02). Negative correlations were observed between duration of AM and A (r = -0.55), F (r = -0.52), and MI (r = -0.57) (p < 0.05). CONCLUSIONS: GE and antral motility parameters were significantly lower in children with AM. A significant correlation was found between symptoms and gastric motility. These findings suggest a possible role of abnormal gastric motility in the pathogenesis of AM.
Abdominal pain predominant functional gastrointestinal diseases in children and adolescents: prevalence, symptomatology and association with emotional stress
(Sri Lanka Medical Association, 2011) Devanarayana, N.M.; Mettananda, S.; Rajindrajith, S.
INTRODUCTION AND OBJECTIVES: To assess the prevalence of abdominal pain predominant functional gastrointestinal diseases (FGD) in Sri Lankan children, their symptomatology, and predisposing factors. METHODS: A cross sectional survey was conducted among a randomly selected group of 10-16 year olds, in 8 randomly selected schools, in 4 provinces in Sri Lanka. A validated, self-administered questionnaire was distributed in an examination setting. Research assistants were present while filling the questionnaire and explanations were given. FGD Were Diagnosed using Rome III criteria. RESULTS: A total of 2180 questionnaires were distributed and 2163 (99.2%) were included in the analysis [1189 (55%) males, mean age 13.4 years, SD 1.8 years]. Seventeen incompletely filled questionnaires were excluded. Two hundred and seventy (12.5%) had at least one abdominal pain predominant FGD. Irritable bowel syndrome (IBS) was seen in 107 (4.9%), functional dyspepsia (FD) in 54 (2.5%), functional abdominal pain in 96 (4.4%) and abdominal migraine (AM) in 21 (1.0%) (2 had AM and FD, 6 had AM and IBS). Extraintestinal somatic symptoms (headache, limb pain, sleeping difficulty) were more common among affected children (p<0.05). Abdominal pain predominant FGD were significantly higher in girls and those exposed to stressful events (p<0.05). Prevalence negatively correlated with age. CONCLUSION: Abdominal pain predominant FGD were a significant health problem in Sri Lankan children affecting 12.5%. IBS was the commonest FGD diagnosed. Abdominal pain predominant FGD were higher in girls and those exposed to emotional stress. Prevalence of FGD decreased with age. Somatic symptoms were more frequent in affected children.
Abdominal pain predominant functional gastrointestinal diseases: association with child abuse, traumatic life events and quality of life
(Wiley Blackwell Scientific Publications, 2012) Devanarayana, N.M.; Rajindrajith, S.; Karunanayake, A.; Nishanthini, S.; Perera, M.S.; Benninga, M.A.
BACKGROUND/AIMS: Abdominal pain predominant functional gastrointestinal diseases (AP-FGD) have significant repercussions on affected individuals. Aims of this study were to assess its association with traumatic life events and child abuse, and its impact on quality of life. METHODS: Children aged 13–18 years were randomly selected from 3 schools in Western province of Sri Lanka. A previously validated, self administered questionnaire was used to collect information on gastrointestinal symptoms, traumatic life events, exposure to abuse, healthcare consultation and quality of life (QOL). AP-FGD were diagnosed using Rome III criteria. RESULTS AND DISCUSSION: A total of 1365 children were recruited [males 749 (54.9%), mean age 14.2 years and SD 1.22 years]. AP-FGD were found in 243 (17.8%) children [Irritable bowel syndrome in 70 (5.1%), functional dyspepsia in 11 (0.8%), abdominal migraine in 26 (1.9%) and functional abdominal pain in 146 (10.7%)]. Prevalence of AP-FGDs were significantly higher in those exposed to traumatic life events (37.9% vs. 3.1%, p = 0.03), sexual abuse (35.3% vs. 17.3%, p = 0.01), physical abuse (19.7% vs. 12.6%, p = 0.0003), and emotional abuse (27.4% vs. 16.9%, p < 0.0001). Health care consultation was significantly higher in children exposed to physical abuse (26.4% vs. 0.0%, p = 0.03). QOL scores for physical (85.7 vs. 89.6), emotional (71.7 vs. 79.4), social (85.9 vs. 92.3) and school (74.3 vs. 81.1) function domains were significantly lower in children with AP-FGD who were exposed to emotional abuse (p < 0.05). QOL scores for school function domain was lower in children exposed to physical abuse (77.8 vs. 83.6, p = 0.03). CONCLUSIONS: Traumatic life events and child abuse in any form are significantly associated with higher prevalence of AP-FGD. Children exposed to physical abuse are more likely to seek healthcare for abdominal pain. Children with AP-FGD, exposed to emotional abuse, have significantly poor quality of life in all four domains.
Abdominal pain predominant functional gastrointestinal disorders in adolescent Nigerians
(Lippincott Williams and Wilkins, 2016) Udoh, E.; Devanarayana, N.M.; Rajindrajith, S.; Meremikwu, M.; Benninga, M.A.
AIMS: To determine the prevalence, pattern and predisposing factors of abdominal painpredominant functional gastrointestinal disorders (AP-FGIDs) in adolescent Nigerians. METHODS: A cross sectional study was conducted in two states in the southern part of Nigeria in June 2014. Adolescents aged 10 - 18 years were recruited from 11 secondary schools using a stratified random sampling technique. A validated self-administered questionnaire on Rome III criteria for diagnosing AP-FGIDs and its determinants were filled by the participants in a class room setting. RESULTS: A total of 874 participants filled the questionnaire. Of this, 818 (93.4%) filled it properly and were included in the final analysis. The mean age of participants was 14.6 ± 2.0 years with 409 (50.0%) being males. AP-FGIDs were present in 81 (9.9%) participants. Among them, 46 (5.6%) had irritable bowel syndrome (IBS), 21 (2.6%) functional abdominal pain, 15 (1.8%) abdominalmigraine while 3 (0.4%) had functional dyspepsia. The difference in AP-FGIDs between adolescents residing in rural and urban areas was not statistically significant (P = 0.22). AP-FGDs was significantly associated with frequent punishment at school (P = 0.03), Intestinal and extra-intestinal symptoms occurred more frequently in those with AP-FGIDs. loss of appetite (56.8% vs. 38.4% in controls), nausea (51.6% vs. 30.0%), headache (76.5% vs. 65.0%), photophobia (56.8% vs. 34.6%) and light-headedness (50.6% vs. 32.6%). Nausea was the only symptom independently associated with AP-FGIDs (p = 0.015). Multiple regression analysis showed no significant association between stressful life events and FGIDs. (P < 0.05). CONCLUSIONS: AP-FGIDs are a significant health problem in Nigerian adolescents. In addition to the intestinal symptoms, most of the affected children had other them also had extra-intestinal symptoms. None of the stressful life events evaluated was significantly associated with FGIDs. Frequent punishment in schools was significantly associated with the condition.
Abdominal pain-predominant functional gastrointestinal diseases in children and adolescents: prevalence, symptomatology, and association with emotional stress
(Lippincott Williams and Wilkins, 2011) Devanarayana, N.M.; Mettananda, S.; Liyanarachchi, C.; Nanayakkara, N.; Mendis, N.; Perera, N.; Rajindrajith, S.
BACKGROUND AND OBJECTIVE: Functional gastrointestinal disorders (FGD) are common among children, but little is known regarding their prevalence in developing countries. We assessed the prevalence of abdominal pain-predominant FGD, in addition to the predisposing factors and symptomatology, in Sri Lankan children. PATIENTS AND METHODS: A cross-sectional survey was conducted among a randomly selected group of 10- to 16-year-olds in 8 randomly selected schools in 4 provinces in Sri Lanka. A validated, self-administered questionnaire was completed by children independently in an examination setting. FGD were diagnosed using Rome III criteria. RESULTS: A total of 2180 questionnaires were distributed and 2163 (99.2%) were included in the analysis (1189 [55%] boys, mean age 13.4 years, standard deviation 1.8 years). Of them, 270 (12.5%) had at least 1 abdominal pain-predominant FGD. Irritable bowel syndrome (IBS) was seen in 107 (4.9%), functional dyspepsia in 54 (2.5%), functional abdominal pain in 96 (4.4%), and abdominal migraine (AM) in 21 (1.0%) (2 had AM and functional dyspepsia, 6 had AM and IBS). Extra intestinal symptoms were more common among affected children (P < 0.05). Abdominal pain-predominant FGD were higher in girls and those exposed to stressful events (P < 0.05). Prevalence negatively correlated with age (r = -0.05, P = 0.02). CONCLUSIONS: Abdominal pain-predominant FGD affects 12.5% of children ages 10 to 16 years and constitutes a significant health problem in Sri Lanka. IBS is the most common FGD subtype present. Abdominal pain-predominant FGD are higher in girls and those exposed to emotional stress. Prevalence of FGD decreased with age. Extra intestinal symptoms are more frequent in affected children.
Abnormal personality traits in children with aerophagia
(Lippincott Williams & Wilkins, 2015) Devanarayana, N.M.; Jayawickrama, N.; Gulegoda, I.C.; Rajindrajith, S.
OBJECTIVE: The main objective of this study is to study the personality types in children with aerophagia. METHODS: A cross sectional survey was conducted in 8 randomly selected schools in 4 randomly selected provinces Sri Lanka. From each school, all children aged 13-18 years were selected after obtaining written consent from parents, school administration and provincial education office. Assent was obtained from all children recruited. Date were collected using a self-administered questionnaire administered under examination setting to ensure confidentiality and privacy. Questionnaire contained previously translated and validated Rome III questionnaire for functional gastrointestinal diseases (self-administered form for children above 10 years) and childhood personality assessment questionnaire. Trained research assistants were present during filling the questionnaire to provide assistance and to verify doubts. Aerophagia was defined using the Rome III criteria. Severities of individual symptoms were recorded in 100 mm visual analogue scale. RESULTS: A total of 1069 questionnaires were distributed and all of them were returned and included in analysis [males 508 (47.5%), mean age 15.3 years, SD 1.8 years years]. One hundred and thirty six (12.7%) fulfilled Rome III criteria for aerophagia and 933 children without aerophagia were considered as controls. Nineteen (13.8%) children with aerophagia and 71 (7.6%) controls had personality scores above the international cut-off value (105) for abnormal personality (p = 0.01). Children with aerophagia had significantly higher scores for different personality traits than controls; including hostility and aggression (13.2 vs. 12.2 in controls, p = 0.006), negative self-esteem (11.0 vs. 9.9, p < 0.0001), negative self-adequacy (10.6 vs. 9.6, p = 0.001), emotional unresponsiveness (10.5 vs. 9.6, p < 0.0001), emotional instability (16.9 vs. 15.7, p < 0.001), negative world view (10.9 vs. 10.1, p = 0.02) and total personality score (92.1 vs. 87.7, p = 001). In children with aerophagia, scores obtained for severity of bloating correlated with scores obtained for hostility and aggression (r = 0.22, p = 0.02). CONCLUSIONS: Children with aerophagia has abnormal personality traits and this fact may at least partly responsible for development and perpetuation of symptoms in them.
Achieving millennium development goal 4 in 2015: are we really on track?
(Sri Lanka College of Paediatricians, 2011) Mettananda, S.; Rajindrajith, S.; Warnakulasuriya, T.; Fernando, M.; Devanarayana, N.M.; Gunawardena, N.K.
INTRODUCTION: Millennium development goal (MDG) 4 aims to reduce under 5 mortality by two thirds from 1990 (22.2 per 1000 live births) to 2015 (7.4 per 1000 live births). In achieving this, proper and accurate description of the causes of deaths is crucial. OBJECTIVES: To describe the timing, causes and distribution of under 5 child deaths in Sri Lanka and to predict the likelihood of achieving MDG 4. DESIGN, SETTING AND METHOD: Information regarding all under 5 child deaths between 2002-2006 was obtained from the Registrar Generals' Department. Place, sex and age at death were retrieved. Causes of deaths documented accordingly to the ICD-10 classification were reclassified into clinically relevant and user-friendly categories. Mortality rates and predictions for 2015 were calculated using Microsoft Excel. RESULTS: A total of 26,273 deaths have occurred during 2002-2006 [55% neonatal, 21% post-neonatal infant and 24% child (l-5year)]. Tsunami wave in 2004 had caused 2,868 (11%) deaths and they were excluded from further analysis. Prematurity had caused 4,603 (31.8%) neonatal deaths; 2389 (16.5%) were due to infections and 1149 (7.9%) were due to birth asphyxia. Congenital anomalies have contributed to 1830 (12.6%) neonatal deaths, of which, the majority [1389 (9.6%)] were heart diseases. Leading causes for post-neonatal infant deaths include congenital anomalies [1772 (35%)], infections [1516 (29.9%)] and trauma [393 (7.7%)]. in children, 910 (23.4%) deaths were due to infections (10.2% respiratory, 2.0% gastroenteritis and 0.9% dengue). One fifth of deaths were due to congenital anomalies of which half were due to heart defects. Trauma/ accidents and malignancies had contributed to 731 (18.8%) and 279 (7.1%) deaths respectively. Colombo district reported the highest number of deaths (24%). More males (54.7%) have died compared to females. Reduction in mortality rates were observed from 2002-2006; neonatal mortality from 8.3 to 7.6, infant mortality from 11.4 to 10.4 and under 5 mortality from 13.7 to 12.3. Projections of data showed that the neonatal, infant and under 5 mortality rates in 2015 would be 4.6, 6.7 and 7.7 per 1000 live births respectively. CONCLUSIONS: Prematurity was the leading cause of neonatal mortality. Congenital heart diseases are an important cause of death throughout childhood. Trauma and accidents contribute to a significant proportion of child deaths. Predictions from data suggest that Sri Lanka may fall marginally short of achieving MDG 4.
Aerophagia among school children: epidemiological patterns and symptom characteristics
(Lippincott Williams & Wilkins, 2011) Devanarayana, N.M.; Rajindrajith, S.
BACKGROUND: Aerophagia is a functional gastrointestinal disease characterized by repetitive air swallowing, abdominal distension, belching and flatulence. In severe cases, it can lead to pneumoperitonium, volvulus and intestinal perforation. Little is known about the epidemiology and clinical profile of affected children. The main objective of this study was to assess the epidemiology of aerophagia in Sri Lankan children and adolescents. METHODS: This cross sectional survey was conducted in 10–16 years old children in 8 randomly selected schools of 4 randomly selected provinces in Sri Lanka. Data were collected using a self-administered questionnaire Questionnaire on Pediatric Gastrointestinal Symptoms - Rome III version, which is translated into native language and pretested for Sri Lankan children). It was distributed in an examination setting and collected on the same day. Trained research assistants were present during the answering of the questionnaire, for any required clarification. Aerophagia was diagnosed using Rome III criteria. RESULTS: In this study, aerophagia was seen in 163 (7.5%), of the 2163 children evaluated. The prevalence was higher in older children (10.5% in 15-year-olds). No gender difference was observed (boys 8.2% vs. girls 6.8%, p>0.05). Other intestinal-related (abdominal pain, nausea and anorexia) and extraintestinal symptoms (headache, limb pain, sleeping difficulty, photophobia and lightheadedness) were more prevalent among affected children ( p<0.05). Out of 163 children with aerophagia, 18 (11%) had difficulty in sleeping and 31 (19.0%) had missed school because of symptoms. Both entities were significantly commoner among children with aerophagia than in controls ( p<0.05). A higher percentage of affected children were found to be exposed to recent stressful life events when compared to controls ( p=0.01). CONCLUSIONS: This study highlights the high prevalence of aerophagia among Sri Lankan children and adolescents. Other intestinal-related and extraintestinal somatic symptoms are frequently seen in affected children. Furthermore, aerophagia has a significant impact on daily activities, such as sleep and schooling, of 10–20% of affected children. This condition is more commonly seen in children exposed to emotional stress
Aerophagia among Sri Lankan schoolchildren: epidemiological patterns and symptom characteristics
(Lippincott Williams and Wilkins, 2012) Devanarayana, N.M.; Rajindrajith, S.
OBJECTIVE: Aerophagia is a functional gastrointestinal disorder characterised by repetitive air swallowing, abdominal distension, belching, and flatulence. In severe cases, it can lead to pneumoperitonium, volvulus of the colon, and intestinal perforation. Little is known about the epidemiology and clinical profile of affected children. The main objective of the present study was to assess the epidemiology of aerophagia in 10- to 16-year-olds in Sri Lanka. METHODS: A school-based cross-sectional survey was conducted in 8 randomly selected schools in 4 randomly selected provinces in Sri Lanka. Data were collected using a pretested, self-administered questionnaire, which was distributed in an examination setting and collected on the same day. Trained research assistants were present during completion of the questionnaire, for any required clarification. Aerophagia was diagnosed using the Rome III criteria. RESULTS: In the present study, aerophagia was seen in 163 (7.5%) of the 2163 children evaluated.

A higher percentage of affected children were found to be exposed to stressful events when compared with controls (P<0.05). CONCLUSIONS: The present study highlights the high prevalence of aerophagia among Sri Lankan children and adolescents. This condition is more common in those exposed to emotional stress. Intestinal-related symptoms and extra intestinal somatic symptoms are frequently seen in affected children.
Aerophagia in adolescents is associated with exposure to adverse life events and psychological maladjustment
(Wiley Blackwell Scientific Publications, 2018) Rajindrajith, S.; Hettige, S.; Gulegoda, I.; Jayawickrama, N.; de Silva, S.C.; Samarakoon, H.K.; de Silva, R.L.; Abeyagunawardena, S.; Devanarayana, N.M.
BACKGROUND: Aerophagia is a common childhood functional gastrointestinal disorder. We studied the association between adverse life events (ALEs), psychological maladjustment, somatization, and aerophagia (AP) in adolescents. We also assessed the impact of AP on their health-related quality of life (HRQoL). METHODS: A cross-sectional survey was conducted on 2500 subjects of 13-18 years in 8 randomly selected schools in Sri Lanka. Translated, validated, and self-administered questionnaires were used to collect data. Aerophagia was diagnosed using Rome III criteria. KEY RESULTS: A total of 2453 questionnaires were analyzed (males 1200 [48.9%], mean age 14.8 years, SD 1.6 years). Of them, 371 adolescents had AP (15.1%). Aerophagia was associated with exposure to physical abuse (20.4% vs. 12.7% in controls, P < .0001), emotional abuse (20.3% vs. 8.2% in controls, P < .0001), and other ALEs (22% vs. 10.2% in controls, P < .001). One hundred and ninety (51.2%) adolescents with AP and 775 (37.2%) controls had a personality score above the international cutoff value of 105, indicating psychological maladjustment (odds ratio 1.77, 95% confidence interval 1.42-2.21, P < .0001). Those with AP had higher somatization (16.4 vs. 8.9) and lower overall HRQoL scores (77.0 vs. 85.1, P < .0001). HRQoL scores of adolescents with AP were lower in all domains, namely, physical (80.6 vs. 86.9), emotional (69.1 vs. 80.3), social (83.8 vs. 90.5), and school (72.6 vs. 82.5) functioning (P < .0001).CONCLUSIONS AND INFERENCES: Aerophagia was associated with exposure to ALEs and psychological maladjustment. Affected teenagers suffer from more somatic symptoms and has a poor HRQoL
Aerophagia in children is associated with emotional ill-treatment.
(Lippincott Williams & Wilkins, 2015) Rajindrajith, S.; Silva, R. L.; Devanarayana, N.M.
BACKGROUND: Aerophagia is a functional gastrointestinal disease characterized by air swallowing, abdominal distension, excessive flatus and belching. The aetiology of this disorder is not clear. Previous studies have suggested an association between aerophagia and psychological stress. We aimed to assess the association between emotional ill-treatment and aerophagia. METHODS: A cross sectional survey was conducted in 4 provinces of Sri Lanka. Children aged 13-18 years were selected from schools in these provinces. A validated, self-administered questionnaires were used for collect data on functional gastrointestinal disease including aerophagia and emotional ill-treatment. Aerophagia was defined using the Rome III criteria. RESULTS: A total of 1069 questionnaires were included in the final analysis (males 508 [47.5%], mean age 15.3 years, SD 1.8 years). One hundred and thirty six (136) children had aerophagia. Prevalence of aerophagia was significantly higher in children who experienced emotional ill-treatments (43 (23.2%) vs. 160 (17.1%), p < 0.0001). Emotional ill-treatments that were significantly associated with aerophagia include, teasing by others (54.1% vs. 45.0%, p < 0.0001), humiliation (38.2% vs. 20.3%, p < 0.0001), treating inferiorly by others (22.8% vs. 11.1%, p < 0.0001), threatening to abandon (8.8% vs. 2.6%, p < 0.0001), threatening destroy belongings (14.0 vs. 4.5%, p < 0.0001), and forcing to do unwanted deeds (9.6% vs. 3.9, p = 0.003). Parenting factors such as refusal of attending to emotional needs (8.8% vs. 3.0%, p < 0.001), refusal to look at (6.6% vs. 0.7%, p < 0.0001), refusal of hugging (10.5% vs. 5.6%, p = 0.03), and not appreciating achievements (5.9% vs. 2.1%, p < 0.0001) were significantly common among children with aerophagia. CONCLUSIONS: Aerophagia in children is associated with emotional ill-treatments. Attending to child's emotional needs likely reduce the prevalence of aerophagia and its consequences.
Aerophagia in teenagers: association with child abuse, adverse life events, somatisation and quality of life
(Japanese Society of Neurogastroenterology and Motility (JSNM), Asian Neurogastroenterology and Motility Association(ANMA), 2017) Devanarayana, N.M.
BACKGROUND: Aerophagia (AP) is characterized by air swallowing, abdominal distension, excessive flatus and belching. Psychological factors are considered as a possible pathophysiological mechanism for AP. We aimed to assess association between aerophagia and exposure to abuse and adverse life events (ALEs), and its effects on somatisation and health related quality of life (HRQoL) in teenagers. METHODS: A cross sectional survey was conducted in 13 to 18 year-olds in 8 randomly selected schools in 4 provinces of Sri Lanka. Translated and validated, self-administered questionnaires were used in data collection. Written parental consent and assent was obtained from all participants. AP was diagnosed using the Rome III criteria. RESULTS: A total of 2453 questionnaires was included in the final analysis (males 1200 [48.9%], mean age 14.8 years, SD 1.6years). Of them, 371 teenagers had AP (15.1%). AP is associated with exposure to physical abuse (20.4% vs. 12.7% in controls), emotional abuse (20.3% vs. 8.2%) and ALEs (22% vs. 10.2%) (p<0,001). ALEs that were associated with AP include, a parent living away from home (20.6% vs. 14.4%), child staying in a hostel (27.1% vs. 14.7%), father’s alcoholism (24.3% vs. 13.4%), and substance abuse (21.8% vs. 14.6%), and quarrels with neighbours (27.7% vs. 13.5%) (p<0.001). Teenagers with AP had higher somatization (16.4 vs 8.9) and lower overall HRQoL (77.0 vs. 85.1) scores than controls (p<0.0001). HRQoL scores were lower in all four domains, namely, physical (80.6 vs. 86.9), emotional (69.1 vs. 80.3), social (83.8 vs 90.5) and school (72.6 vs. 82.5) functioning (p<0.0001). CONCLUSIONS: AP in teenagers is associated with exposure to physical abuse, emotional abuse and ALEs. Affected teenagers have significantly more somatic symptoms. Although considered as benign, AP leads to significant impairment of HRQoL in teenagers
Aetiology of recurrent abdominal pain in a cohort of Sri Lankan children
(Wiley-Blackwell, 2008) Devanarayana, N.M.; de Silva, D.G.H.; de Silva, H.J.
AIMS: Recurrent abdominal pain (RAP) has a multifactorial aetiology with many affected children having no evidence of organic pathology. This study assessed the functional and organic causes for RAP in a cohort of Sri Lankan children. METHODS: Fifty-five Sri Lankan children (45.5% males, aged 5-15 years) having RAP were screened for organic diseases. RAP was defined using Apley criteria. Children without clinical or laboratory evidence of organic diseases were classified into functional gastrointestinal diseases (FGD) using Rome II and III criteria. Thirty-nine patients with functional RAP and 20 healthy children (50% males, age 5-15 years) from same area were tested for Helicobacter pylori using a stool antigen test. RESULTS: Thirteen (23.6%) children had organic RAP. According to Rome II, 33 (60%), and according to Rome III, 39 (71%) (functional abdominal pain 19, irritable bowel syndrome nine, functional dyspepsia nine, abdominal migraine one, aerophagia one) children had FGD. Two (5.1%) patients and one (5%) control tested were positive for Helicobacter pylori (P > 0.05). Except for constipation, pain characteristics and associated symptoms were not significantly different between organic and functional RAP. CONCLUSIONS: Organic pathology accounted for symptoms in less than a quarter of Sri Lankan children with RAP. The majority had functional bowel diseases, of which the commonest was functional abdominal pain. Rome III criteria were more effective than Rome II criteria in identifying FGD. Helicobacter pylori infection did not appear to be associated with RAP.

(Sri Lanka Medical Association, 2011) Mettananda, S.; Warnakulasuriya, T.; Fernando, M.; Devanarayana, N.M.; Rajindrajith, S.
INTRODUCTION AND OBJECTIVES: To describe the causes, timing and distribution of neonatal deaths in Sri Lanka from 2002 to 2006. METHODS: Information on all neonatal deaths occurred from 2002 to 2006 (5 calendar years) in the entire country was obtained from the Registrar Generals' Department. Place of death and age at death were retrieved. Causes of death documented as 429 different diagnoses according to the ICD-10 classification were reclassified into clinically relevant and meaningful categories. Results: A total of 14,487 neonatal deaths occurred during the 5-year period with a mean of 2897.4 deaths per year; of which 8159 (56.32%) were males. One third of them (4904) died within 24 hours of life and 11,318 (78.12%) were early neonatal deaths. Number of deaths gradually decreased with increasing age. Colombo district reported 3334 (23.0%) deaths. Prematurity and related complications were the cause for 4603 (31.77%) deaths whereas 2389 (16.49%) deaths were due to infections. Proportion of deaths due to infections has gradually decreased from 20.23% in 2002 to 11.84% in 2006. Congenital anomalies contributed to 12.63% (1830) deaths and the majority of those deaths (1389-9.59%) were due to congenital heart diseases. Birth asphyxia had caused 1349 (7.93%) neonatal deaths. Tsunami wave in 2004 has led to 36 (0.25%) neonatal deaths. CONCLUSIONS: Preventable causes such as prematurity, infections and congenital heart diseases are still leading causes of neonatal deaths in Sri Lanka. Targeted healthcare reforms are urgently needed to address these issues.
Assessment of exposure of gas station attendants in Sri Lanka to benzene, toluene and xylenes.
(Amsterdam, Elsevier, 2019) Scheepers, P.T.J.; de Werdt, L.; van Dael, M.; Anzion, R.; Vanoirbeek, J.; Duca, R.C.; Creta, M.; Godderis, L.; Warnakulasuriya, D.T.D.; Devanarayana, N.M.
ABSTRACT:Exposure to benzene, toluene and p-, m-, o-xylene (BTX) was studied in 29 gas station attendants and 16 office workers in Sri Lanka. The aim of this study was to assess the exposure level and identify potential exposure mitigating measures. Pre- and post-shift samples of end-exhaled air were collected and analysed for BTX on a thermal desorption gas chromatography mass spectrometry system (TD-GC-MS). Urine was collected at the same timepoints and analysed for a metabolite of benzene, S-phenyl mercapturic acid (SPMA), using liquid chromatography-mass spectrometry (LC-MS). Environmental exposure was measured by personal air sampling and analysed by gas chromatography flame ionization detection (GC-FID). Median (range) breathing zone air concentrations were 609 (65.1-1960) μg/m3 for benzene and 746 (<5.0-2770) μg/m3 for toluene. Taking into account long working hours, 28% of the measured exposures exceeded the ACGIH threshold limit value (TLV) for an 8-h time-weighted average of 1.6 mg/m3 for benzene. Xylene isomers were not detected. End-exhaled air concentrations were significantly increased for gas station attendants compared to office workers (p < 0.005). The difference was 1-3-fold in pre-shift and 2-5-fold in post-shift samples. The increase from pre-to post-shift amounted to 5-15-fold (p < 0.005). Pre-shift BTX concentrations in end-exhaled air were higher in smokers compared to non-smokers (p < 0.01). Exposure due to self-reported fuel spills was related to enhanced exhaled BTX (p < 0.05). The same was found for sleeping at the location of the gas station between two work-shifts. Benzene in end-exhaled air was moderately associated with benzene in the breathing zone (r = 0.422; p < 0.001). Median creatinine-corrected S-phenyl mercapturic acid (SPMA) was similar in pre- and post-shift (2.40 and 3.02 μg/g) in gas station attendants but increased in office workers (from 0.55 to 1.07 μg/g). In conclusion, working as a gas station attendant leads to inhalation exposure and occasional skin exposure to BTX. Smoking was identified as the most important co-exposure. Besides taking preventive measure to reduce exposure, the reduction of working hours to 40 h per week is expected to decrease benzene levels below the current TLV.
Assessment of gastric emptying and antral motility in different types of abdominal pain related functional gastrointestinal diseases: a paediatric study
(BMJ Publishing, 2010) Devanarayana, N.M.; Rajindrajith, S.
INTRODUCTION: Functional gastrointestinal disorders (FGD) are common among paediatric population. Abdominal pain related FGD are the most common subgroup found, of which irritable bowel syndrome is the most common. The exact mechanism of pain remains unclear in FGD. Visceral hypersensitivity and altered gastrointestinal motility are considered possible causes for abdominal pain and discomfort found in these children. METHODS: The main aim of this study was to evaluate the gastric emptying and antral motility in children and adolescents with abdominal pain related FGD. Hundred and fifty-five children referred to the Gastroenterology Research Laboratory who fulfilled Rome III criteria for abdominal pain related FGD (60 (38.5%) males, 4–14 years, mean 8.1 years, SD 2.6 years) and 20 healthy children without gastrointestinal symptoms (8 (40%) males, 4–15 years, mean 8.9 years, SD 2.7 years) were recruited. None had clinical or laboratory evidence of organic diseases. All subjects underwent ultrasonographic assessment of liquid gastric emptying rate (GE) and antral motility, using a previously reported method. RESULTS: Gastric motility parameters of children with FGD and controls are presented in the table. GE negatively correlated with the scores obtained for severity of symptoms in functional dyspepsia (FD) (r=−0.67, p<0.001) and functional abdominal pain (FAP) (r=−0.38, p<0.001), but not in irritable bowel syndrome (IBS) (r=−0.16, p=0.29). CONCLUSIONS: GE and antral mortality parameters were significantly impaired in children with all types of abdominal pain related FGD. GE negatively correlated with symptoms in FD and FAP. Mortality parameters were not significantly different between subtypes of IBS.
The Association between adverse life events and abdominal pain-predominant functional gastrointestinal disorders.
(Lippincott Williams & Wilkins, 2015) Devanarayana, N.M.; Rajindrajith, S.; Benninga, M.A.
BACKGROUND: Abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs) are a common public health problem in children. The precise aetiology of AP-FGIDs is far from clear. Psychological stress and all forms of child abuse are known predisposing factors to develop AP-FGIDs. The main objective of this study is to study the association between adverse life events (ALEs) and development of AP-FGIDs. METHODS: A cross sectional, school based study was conducted in Gampaha district of Sri Lanka. All children aged 13-18 years were recruited from four randomly selected semi-urban schools in the district after obtaining consent from parents, school administration and children themselves. A translated and validated, self-administered questionnaire consisting of four parts was used for data collection. Part I was the Rome III questionnaire for functional gastrointestinal disorders, self-report form for children above 10 years. Part II was a questionnaire on exposure to adverse life events. Part III was the Sinhala (the native language) version of the PedsQL, Pediatric Quality of Life Inventory 4.0 (Generic Core Scales). Part IV was the Child Somatization Inventory. The questionnaire was administered under examination setting to ensure confidentiality and privacy. Research assistant were present during filling the questionnaire for provide assistance and verifications. AP-FGIDs were defined using the Rome III criteria. RESULTS: A total of 1792 children were included in the analysis (males 975 [54.4%], mean age 14.4 years, SD 1.3 years years). Out of them, 305 (17.0%) had AP-FGIDs. ALEs that showed a significant association with AP-FGIDs include, parental substance abuse (25.1% vs. 16.0% in controls, p = 0.015) and domestic violence (28.5% vs. 16.1%, p = 0.02). Children with AP-FGIDs exposed to ALEs have a higher somatization index compared to children not exposed to ALEs (16.9 vs. 13.4, p = 0.003), and a lower overall health-related quality of life (HRQoL) score (81.8 vs. 85.1, p = 0.02). The scores they obtained for psycho-social (86.4 vs. 92.4, p < 0.0001) and emotional (72.5 vs. 77.7, p = 0.03) domains of the HRQoL were also lower than that of children with no such experiences. CONCLUSIONS: Exposure to ALEs predispose children to develop AP-FGIDs. Experience of childhood ALEs deleteriously affects the HRQoL and somatization of children with AP-FGIDs.

(Lippincott Williams and Wilkins, 2014) Rajindrajith, S.; Devanarayana, N.M.; Lakmini, C.; Subasinghe, V.; de Silva, D.G.H.; Benninga, M.A.
Child abuse leads to multiple physical and psychosomatic sequelae. The aim of the present study was to evaluate the association between child abuse and constipation among schoolchildren. METHODS: Children 13 to 18 years of age were selected from 4 semiurban schools in Gampaha District, Sri Lanka. A self-administered questionnaire was used for data collection. Information regarding socio demographic factors and gastrointestinal symptoms, child abuse, and somatisation were collected. Constipation was diagnosed using Rome III criteria. RESULTS: A total of 1792 children were included in the analysis (boys 975 [54.4%], mean age 14.4 years, standard deviation [SD] 1.3 years). One hundred thirty-eight (7.7%) fulfilled Rome III criteria for constipation. The number of children exposed to physical, emotional, and sexual abuse were, respectively, 438 (24.4%), 396 (22.1%), and 51 (2.8%). The prevalence of constipation was significantly higher in those exposed to sexual (5.8% vs 2.6% P = 0.03), emotional (40.9% vs 20.8%, P < 0.0001), and physical abuse (41.6% vs 23.2%, P < 0.0001). Mean somatisation score was higher in the total group of abused children with constipation (mean 18.6, SD 12.5) compared with those without (mean 13.9, SD 12.3; P = 0.027). Children with a history of abuse did not seek health care more often than children without this history. Patient-perceived severity of bowel symptoms was higher in children with physical abuse (23.7 vs 19.7 P = 0.001) and emotional abuse (25.4 vs 19.3 P < 0.0001). CONCLUSIONS: Childhood constipation shows a significant association with physical, sexual, and emotional abuse. Children with constipation complain of more somatic symptoms and bowel symptoms when they are exposed to abuse.

(Blackwell Scientific Publications, 2022) Liyanarachchi, H.; Rajindrajith, S.; Kuruppu, C.; Chathurangana, P.; Ranawaka, R.; Devanarayana, N.M.; Benninga, M.A.
BACKGROUND: Several cross-sectional studies have reported an association between childhood constipation and exposure to stressful events. We planned to systematically review the literature on constipation and its associated stressful events. METHODS: PubMed, Embase, and PsycINFO databases were searched (until February 2021) using standard search terms related to "constipation" and "stress" from 0 to 18 years that describe the association between psychological stressors and constipation. Studies were screened using pre-designed eligibility criteria. Studies that fulfilled the criteria were reviewed in a full-text format. The quality assessment of selected articles was conducted using standard methods. KEY RESULTS: Of 2296 titles and abstracts screened, 38 were included in the full-text review. Out of that, 15 articles were included in this systematic review. There were 2954 children with constipation, and the age range was from 6 months to 16 years. Exposure to home-related stressors (divorce or separation of parents, severe illness in family, and parental job loss) school-related stressors (including being bullied at school, change in school, separation from the best friend at school, and failure in an examination), exposure to child maltreatments and exposure to war/civil unrest were associated with childhood constipation. CONCLUSIONS AND INFERENCES: Exposure to day-to-day home- and school-related stressors, to child maltreatment, and to civil unrest is associated with constipation in children and adolescents. These factors need to be explored during clinical evaluation of children with constipation. KEYWORDS: adolescents; child maltreatment; children; civil unrest; constipation; stress.
