Correlation between Soil-Transmitted Helminths Infection and Serum Iron Level among Primary School Children in Medan

BACKGROUND The latest estimates indicate that more than 2 billion people worldwide are infected by Soil-Transmitted Helminths (STH). The burden of STH infection is mainly attributed to the chronic effect on health and quality of life of those infected. It is also contributed to micronutrient deficiencies such as iron-deficiency anaemia. The prevalence of worm infection in Public Primary School students in Medan was quite high (40.3%), and 33.3% was anaemic in the latest study. AIM To determine the correlation between STH infection with serum iron (SI) level on primary school children, as well as to determine the prevalence of SI level and worm infection, and the type of worm that infects the most of them. METHODS This study was conducted in the cross-sectional method. Consecutive sampling technique was used and a total of 132 students age 8-12 years old were included. The study took places in Public Primary School 060925 Amplas, Medan and 101747 Hamparan Perak, Deli Serdang throughout May-October 2016. Fisher Exact test was used to analyse the correlation between STH infection and SI level. RESULTS The prevalence of STH infection was 7.6%, and low SI was 11.4%. CONCLUSION There was no significant correlation between STH infection and SI level (P = 0.317). The prevalence of low SI level was not significantly dependent on STH infection (RP = 1.877, 95% CI = 0.481-7.181).
