Association between intestinal helminth infections and mid-upper-arm circumference among children in Sri Lanka: A cross-sectional study
Published online by Cambridge University Press: 15 June 2017
Abstract
Intestinal helminth infections constitute a major health problem in low socio-economic communities worldwide. A cross-sectional study was conducted in children aged between 12 and 60 months. A structured questionnaire was used to collect socio-demographic data and stool samples were subjected to direct smear, stained with Lugol's iodine, and formaldehyde–ether concentration techniques to determine the prevalence of intestinal helminth infections. The circumference of each child's left mid upper arm (MUAC) was measured using standard procedures. Two hundred and six children with a mean MUAC of 14.7 cm (SD ± 1.1) were assessed from September to December 2014. The prevalence of acute energy undernutrition was 6.3% (13/206). All of them had moderate acute undernutrition and no cases of severe acute undernutrition. Paternal occupation was significantly associated with MUAC. Intestinal helminth infections were detected in 12.6% of children. Four species of parasites were identified; Ascaris lumbricoides (9.7%) followed by Enterobius vermicularis (1.5%), Trichuris trichiura (1.0%) and hookworms (1.0%). Uninfected children aged between 1 and 2 years showed significantly higher MUAC than infected children. No statistically significant association was detected between the severity of intestinal helminth infections and MUAC. Although intestinal helminth infections are a major public health problem in this community, they are not related to MUAC. Future research, providing more insight into the nutritional impact of intestinal helminth infections, is required to determine the association between parasitic infections and physical growth in this community.
