Objective To understand the infection status and main risk factors of soil ? transmitted nematodes in southwest China so as to provide the evidence for making the control programs for soil?transmitted nematodiasis. Methods The prevalence of soil?transmitted nematode infections was determined by Kato?Katz technique and influencing factors were surveyed by using a standardized questionnaire,and in part of the children,the examination of Enterobius vermicularis eggs was performed by using the cellophane swab method. The relationship between soil? transmitted nematode infections and influencing factors was analyzed by the multiple probit estimated method. Results A total of 1 707 children were examined,with a soil?transmitted nematode in? fection rate of 22.2%,the crowd infection rates of Ascaris lumbricoides,hookworm,and Trichuris trichiura were 16.0%,3.8% and 6.6% respectively and 495 children were examined on Enterobius vermicularis eggs,with the infection rate of 5.1%. The results of probit estimated analysis suggested that the effects of 4 factors on soil?transmitted nematode infections were significant(all P val? ues were less than 0.05), namely the number of sib, educational level of mother, drinking unboiled water and raising livestock and poultry. Among the factors above,the educational level of mother could reduce the probability of infection(ME= -0.074), while the number of sib,drinking unboiled water and raising livestock and poultry could increase the probability of the infections(with ME of 0.028, -0.112 and 0.080,respectively) . Conclusions Soil?transmitted nematode infection rates are still in a high level for children in southwest poor areas of China,with Ascaris lumbricoides as a priority. The changes of children’ s bad health habits, raising livestock and poultry habits,and implementing the health education about parasitic diseases in mothers would be of great significance for the prevention and control of soil?transmitted nematodiasis.
