Objective: Infection by the protozoan parasite Toxoplasma gondii is generally prevalent in animals and humans worldwide. However, little is known about T. gondii infection among children in China. Thus, the present study was conducted to detect the seroprevalence of T. gondii infection and estimate associated risk factors among children in eastern China. Methods: A cross-sectional study of 1500 children from three cities (Changchun, Qingdao, Weihai) was conducted between May 2013 and July 2014 to estimate the seroprevalence and potential risk factors associated with acquiring T. gondii infection in children in China. Demographic and blood samples were collected, and anti-T. gondii IgG and IgM antibodies were measured by ELISA. Results: The mean age of the 1500 children participating in the study was 9.03 years (range 1-18). The overall seroprevalence of Toxoplasma infection was 15.13%, of which 13.13% were positive for only antiToxoplasma IgG antibodies, 3.13% were positive for both anti-Toxoplasma IgG and IgM antibodies and 2.00% were IgM positive and IgG negative. Moreover, raising cats at home (OR=1.94, 95% CI=1.288-2.912, P=0.002) and hand washing habits (OR=0.38, 95% CI=0.230-0.635, P
