Prevalence of functional constipation in infants and toddlers in Sri Lanka.

Abstract

OBJECTIVE: To determine the prevalence of functional constipation (FC) in toddlers in Sri Lanka and to identify risk factors associated with the development of FC, such as demographic features, social and economic factors. METHODS: Children between 7 months and 5 years of age were selected from 14 well baby and vaccination clinics in the Gampaha District, Sri Lanka. Data were collected using a self-administered questionnaire. The questionnaire contained questions regarding the child's bowel habits, socio-demographic characteristics as well as physical and verbal violence against mother and/or child. Functional constipation was diagnosed according to ROMEIII criteria. RESULTS: A total of 1151 toddlers were included in the analysis, (female n = 588 [50,8%], mean age 21,7 months, standard deviation [SD] 12,5 months). A total of, 92 children (8,0%) fulfilled the Rome III criteria for FC. The prevalence of constipation was significantly and independently associated with first birth order (9,6% vs. 6,5% p = 0,026), underweight [<2SD] (15,0% vs. 7,1%, p = 0,004) and living in an urban residence (9,5% vs. 5,8%, p = 0,023). Odds ratios [OR] and 95% confidence intervals [CI] are were respectively 1,61 (CI; 1,02-2,53), 2,53 (CI; 1,45-4,41), 1,70 (CI; 1,08-2,69). Toddlers being overweight, being subject to violence or with mothers subject to violence illustrated higher prevalence of FC, but p-values were >0,05. No association was found with gender, age, parental age, parental education level, shortage in income and quality of relationship between parents. CONCLUSIONS: Functional constipation is a significant health problem in toddlers in Sri Lanka, concerning 8 percent of its population between 7 months and 5 years old. Toddlers being first born, underweight and living in an urban area show a significant higher risk for FC.
