摘要
目的基于潜类别增长模型分析男男性行为者HIV检测自我效能的变化趋势。方法于2019年8月至2021年5月,在山东省招募404名男男性行为(MSM)人群并进行1年的随访研究,采用个体干预(微信及随访问卷中推送干预图片和视频)与社区干预(朋友圈转发、微信群分享讨论HIV检测相关信息),测量其HIV检测自我效能水平,并采用潜类别增长模型(LCGM)分析HIV检测自我效能的长期发展趋势,并分析发展趋势的影响因素。结果404名MSM年龄为(28.25±8.95)岁,最大58岁,最小18岁;基线和4次随访的HIV检测自我效能得分M(Q_(1),Q_(3))分别为18.00(17.00,21.00)、19.00(18.00,22.00)、19.00(18.00,22.00)、19.00(18.00,22.00)、19.00(18.00,22.00)。自由估计的两分类LCGM模型分析结果显示,MSM的HIV检测自我效能发展趋势可分为两类,分别是“干预反应组”[255名(63.1%)]和“干预无反应组”[149名(36.9%)],“干预反应组”的MSM人群HIV检测自我效能水平较高,且随时间先上升后下降;而“干预无反应组”水平较低且较为稳定。多因素logistic回归分析结果显示,以学生MSM人群为参照组,商业或服务业、无业或失业的MSM的OR值分别为0.261(95%CI:0.108~0.633)和0.186(95%CI:0.057~0.610)。结论MSM人群在干预条件下的HIV检测自我效能变化趋势存在群体异质性,职业可能是影响因素。
Objective To analyze the trajectories of HIV testing self-efficacy among men who have sex with men(MSM)based on latent class growth model.Methods From August 2019 to May 2021,404 MSM were recruited in Shandong Province and subjected to a 1-year follow-up study with individual intervention(pushing intervention pictures and videos in WeChat and follow-up questionnaires)and community intervention(forwarding to friends and sharing and discussing HIV testing-related information in WeChat groups).The level of HIV testing self-efficacy among MSM was measured.The long-term trend of HIV testing self-efficacy was analyzed using the latent class growth model(LCGM),and the influencing factors of the trend were analyzed.Results A total of 404 MSM were(28.25±8.95)years old,with the oldest being 58 and the youngest being 18.The scores of HIV testing self-efficacy M(Q_(1),Q_(3))at baseline and 4 follow-ups were 18.00(17.00,21.00),19.00(18.00,22.00),19.00(18.00,22.00),19.00(18.00,22.00)and 19.00(18.00,22.00).The results of the freely estimated two-category LCGM model showed that the trend of HIV testing self-efficacy among MSM could be divided into two classes,"intervention response group"[255(63.1%)]and"intervention non-response group"[149(36.9%)].The former had a higher level of HIV testing self-efficacy which tended to increase at first and then decrease over time,while the latter had a lower and more stable level.The results of the multifactorial logistic regression analysis showed that the OR values of MSM in business or service and jobless or unemployed were 0.261(95%CI:0.108-0.633)and 0.186(95%CI:0.057-0.610),respectively,using the students as the reference group.Conclusion There is a group heterogeneity in the trend of HIV testing self-efficacy in the intervention conditions among MSM,and occupation may be an influencing factor.
