Child abuse and abdominal pain - Is there an association?

Abstract

INTRODUCTION AND AIMS: It is believed that there is an association between abdominal pain and child abuse. The main objective of this study was to assess this association in Sri Lankan school children. METHODS: Children aged 13-18 years were randomly selected from a semi-urban school in Gampaha district. A previously validated, self administered questionnaire was used to collect socio-demographic data and information on gastrointestinal symptoms, child abuse and exposure to other stressful events. Severity of symptoms was recorded using a validated, visual analogue scale. Children with abdominal pain were categorized into abdominal pain predominant functional gastrointestinal disorders (AP-FGD) using Rome III criteria. RESULTS: A total of 490 children were recruited [males 254 (51.8%), mean age 15.2 years and SD 1.64 years]. Forty eight (9.8%) fulfilled Rome lit criteria for AP- FGD (functional dyspepsia=3, functional abdominal pain=25, irritable bowel syndrome=15 and abdominal migraine=5). The number of children exposed to physical, emotional and sexual abuse, were respectively 119 (24.3%), 109 (22.2%) and 18 (3.8%). Prevalence of AP-FGD was significantly higher in those exposed to sexual (26.7% vs. 9.3% in controls, p=0.42) and emotional (16.5% vs. 8.3%, p=0.046) abuse, but not physical abuse (11.8% vs. 9.2%, p=0.69). AP-FGD type associated with sexual abuse was irritable bowel syndrome (15.4% vs. 2.7%, p=0.02). Mean scores obtained severity of abdominal pain were higher in children exposed to sexual (27.9 vs. 13.2, p=0.002) and emotional abuse (22.1 vs. 11.4, p<0.001). CONCLUSIONS: Chronic abdominal pain prevalence and severity were significantly higher in children exposed to sexual and emotional abuse.
