Methods: Data for this analysis was obtained from a 2011 Pan American Health Organization (PAHO) survey on children aged 8 to 10 years in El Salvador. The survey collected demographic, behavioral, environmental, and STHI infection data of 1310 children, including the source of drinking water by municipalities. Source of piped water in El Salvador is by the ‘Administracion Nacional de Acueductos y Alcantarillodos’ (ANDA) agency in EL Salvador, contracted decentralized operators and/or non-decentralized operators. Descriptive statistics was done to understand the study population and logistic regression was conducted to determine the association between STHI infection and drinking water supply in the study population.
Results: Of the 1310 children, 49.01% (n=642) were male and 30.46% (n=399) were 8 year olds. The prevalence of STHI infections in the study population was 2.75% for Ascaris lumbricoides , 4.10% for Trichuris trichiura and 1.83% for hookworm. Source of drinking water supply was significantly associated with STHI infection in the study population. Compared to individuals who resided in areas supplied by ANDA, individuals who resided in areas supplied by the decentralized operators under contract management were 4 times more likely to be infected with Ascaris lumbricoides. While amongst individuals who resided in areas receiving drinking water through piped supply by decentralized operators under contract management, the risk of infection was 2.8 times higher than amongst those who resided in areas receiving drinking water through piped supply by decentralized operators not under contract management
Conclusion: Our results show that there is a significant association between the piped drinking water supply and Ascaris lumbricoides infection in the study population.
