A community-based seroepidemiologic survey on Taenia solium cysticercosis in humans was carried out in Shandong Province, China. Blood specimens from 2,898 residents were collected and examined for anti-cysticercus antibody. Information on demographic and potential risk factors was obtained using a standardized questionnaire. The overall seroprevalence of cysticercosis was 3.2%. Seropositivity tended to increase with age ranging from 1.8% in children under 6 years of age to 5.7% in those over 60 years old. Distance between village residence and the town of the community was negatively associated with seropositivity (Chi-square for trend test p = 0.02). Multivariate logistic regression analysis identified four risk factors for cysticercosis infection in the community: defecating indiscriminately (OR = 1.35, 95% CI 1.01-1.81), being unable to identify diseased pork (OR = 4.09, 95% CI 1.53-10.97), raising pigs (OR = 1.36, 95% CI 1.09-1.69), and more than 60 years old (OR = 1.49, 95% CI 1.10-2.02. These findings have implications for developing appropriate strategies for the control of Taenia solium cysticercosis in the community.
