title: Some risk factors of Ascaris and Trichuris infection in Malaysian aborigine (Orang Asli) children.
abstract: A study on risk factors of soil-transmitted helminths was conducted in a highly endemic area. In all 205 children (95 boys and 110 girls) participated in this study. The overall prevalences of Ascaris, Trichuris and hookworm infection were 62.5%, 91.7% and 28.8% respectively. Only 22.4% of the children had a single infection either by Ascaris or Trichuris; 69.3% had mixed infection and the most prevalent of mixed infection was a combination of Ascaris and Trichuris. Logistic regression analysis confirmed that low level mother's education was a risk factor for moderate and severe infection of Ascaris and age < or = 6-year-old was a protective factor. In Trichuris infection logistic regression analysis confirmed that usage of well-water and age < or = 6-year-old were the risk factors. Logistic regression analysis on worm scores confirmed that usage of well-water and non-usage of toilets were the risk factors from getting severe worm scores and age < or = 6-year-old was a protective factor. Our finding suggest that socio-behavioural (related to mother's education), demographic (children age) and environmental-factors (usage of well-water and non-usage of toilets) are the elements to be considered in the design of long term soil-transmitted helminths (STH) control in an endemic areas.
