摘　　要：目的利用微信公众号对存在艾滋病风险行为的大众人群开展艾滋病健康教育并进行效果及可行性评价。方法将2021年4月通过线上招募并完成基线调查的四川省内存在易感染艾滋病风险行为的大众人群作为调查对象,最终成功入组719人,随机分为干预组(465人)以及对照组(254人)。所有入组者均接受“常规健康教育”;干预组还需接受基于风险感知干预策略的“精准干预”。在第1个月和第6个月对入组者进行线上问卷随访。运用χ^(2)检验和logistic回归模型分析非婚和不安全性行为变化的影响因素。结果第1个月和第6个月随访的应答比例分别为67.45%和79.83%。多因素logistic回归分析显示,性取向为非异性是干预后仍发生不安全性行为的危险因素(2次随访的OR值分别为3.639和2.733),干预组较之对照组发生不安全性行为的风险更低(2次随访的OR值分别为0.531和0.644);在控制了性别、性取向、婚姻状况等影响因素后,接受干预对减少近1个月非婚性行为频次有一定的积极作用,干预后第1个月随访时,接受干预的保护作用更明显(2次随访的OR值分别为0.333和0.536)。结论以提高风险感知为目的的“精准干预”在减少不安全性行为和非婚性行为频次方面的效果优于常规健康教育。Objective To evaluate the effects and feasibility of using WeChat public platform to carry out HIV health education for the general public with HIV risk behaviors.Methods The general public with risk behaviors in Sichuan susceptible to HIV infection who were recruited online and completed the baseline survey in April 2021 were selected as the survey subjects.719 people were successfully enrolled and randomly divided into the intervention group(465 people)and the control group(254 people).All enrolled participants received“routine health education”.The intervention group additionally received“precise intervention”based on risk perception intervention strategies.Participants were followed up with online questionnaires at the 1st and 6th months.Theχ^(2)test and logistic regression were used to analyze the influencing factors of changes in non-marital and unsafe sexual behaviors.Results The response rates at 1-month and 6-month follow-ups were 67.45%and 79.83%,respectively.Multivariate logistic regression analysis showed that non-heterosexual sexual orientation was a risk factor for unsafe sex after the intervention(OR values obtained at two follow-up visits were 3.639 and 2.733,respectively),and the risk of having unsafe sex in the intervention group was lower than the control group(OR values obtained at two follow-up visits were 0.531 and 0.644,respectively).After controlling for factors such as gender,sexual orientation,marital status,and other influencing factors,receiving intervention had a positive effect on reducing the frequency of non-marital sex in the past 1 month.The protective effect of the intervention was more pronounced at follow-up at the first month after the intervention(OR of 0.333 and 0.536 at two followups,respectively).Conclusions The effect of“precision intervention”aimed at improving risk perception in reducing the frequency of unsafe sex and non-marital sex is better than conventional health education.
