Objective To understand the current situation and influencing factors of knowledge,attitudes,and practice of childhood sexuality education among parents in Xichang city,thus providing a basis for improving the current situation of childhood sexuality education and promoting related work of family sexuality education. Methods Through cluster random sampling,8 kindergartens were selected in Xichang city,Sichuan province.A self-designed questionnaire on parents’ knowledge,attitudes,and practice of childhood sexuality education was used to conduct an anonymous survey on parents of young children who were selected from the kindergartens.The data were analyzed by chi-square test and multivariate Logistic regression model. Results The rates of knowledge awareness,positive attitude,and good practice among the 1 496 parents were 3.9%,32.0%,and 36.6%,respectively,and the overall good rate of knowledge,attitudes,and practice was 22.9%.The results of multivariate Logistic regression analysis showed that parents who were of Han ethnicity (OR=1.73,95%CI=1.17-2.56,P=0.006),whose children were female (OR=2.16,95%CI=1.51-3.11,P=0.019),who believed that sexuality education should be the responsibility of parents (OR=2.42,95%CI=1.57-3.73,P<0.001),who had communicated with family and friends about childhood sexuality education (OR=2.95,95%CI=2.22-3.92,P<0.001),and who had conducted sexuality education for their children themselves (OR=1.81,95%CI=1.37-2.40,P<0.001) had higher overall good rates of knowledge,attitudes,and behavior in childhood sexuality education. Conclusions Parents generally have low rates of knowledge awareness,positive attitudes,and good practice and a low overall good rate of knowledge,attitudes,and practice regarding childhood sexuality education.Relevant departments should attach importance to childhood sexuality education,with a particular focus on parents of ethnic minorities and those who have not carried out childhood sexuality education.They should intensify publicity and training efforts to enhance parents’ level of sexuality education,change their attitudes towards sexuality education,and promote the development of family sexuality education.
