Preadolescents, who are in a transitional phase of development, may experience higher exposure to heterosexual interactions while facing higher risks regarding misinformation in sexual knowledge and unsafe engagement in sexual activities. There is a deficiency in the availability of qualified educators and age-appropriate teaching materials for sexuality education in China.
We implemented an animation-based comprehensive sexuality education package among preadolescents aged 9 to 12 years from eight schools in Anhui, China. The first round of intervention included 1,835 participants, lasting 2 months from September to November 2020. A total of 374 participants, accounting for 52% of the intervention group, received a second round of intervention in September 2021. Participants completed immediate follow-up assessment and 1-year follow-up assessment to assess changes in their sexual knowledge, attitudes, and other outcomes. Propensity score matching and difference-in-difference analysis were performed to determine the short- and long-term impacts.
Significant improvements were observed for both sexual knowledge and sexual attitudes in the immediate follow-up. There was no significant effect on pornography-seeking behavior or awareness of experiencing sexual abuse. After 1 year, the effect was sustained for sexual knowledge, but slightly declined for sexual attitudes. The second intervention significantly improved sexual knowledge; however, no significant change in sexual attitudes, pornography-seeking behavior, or awareness of experiencing sexual abuse was observed.
Our comprehensive sexuality education package was effective in improving sexual knowledge both immediately and 1 year after the intervention. Repeated intervention can be an effective strategy for promoting preadolescent health development regarding comprehensive sexuality education.
处于发育过渡阶段的青春期前儿童可能会更多地接触异性互动，同时在性知识错误信息和性活动不安全参与方面面临更高风险。在中国，合格教育工作者的可获得性以及适合年龄的性教育教材都存在不足。
我们在中国安徽八所学校对9至12岁的青春期前儿童实施了基于动画的综合性性教育方案。第一轮干预有1835名参与者，从2020年9月持续到11月，为期2个月。2021年9月，共有374名参与者（占干预组的52%）接受了第二轮干预。参与者完成了即时随访评估和1年随访评估，以评估他们性知识、态度及其他结果的变化。进行倾向得分匹配和差分分析以确定短期和长期影响。
在即时随访中，性知识和性态度均有显著改善。对寻求色情行为或遭受性虐待的认知没有显著影响。1年后，性知识的效果持续存在，但性态度的效果略有下降。第二次干预显著改善了性知识；然而，性态度、寻求色情行为或遭受性虐待的认知没有显著变化。
我们的综合性性教育方案在干预后即时及1年时均有效地改善了性知识。重复干预可能是促进青春期前儿童在综合性性教育方面健康发展的有效策略。
