To evaluate the effectiveness of AIDS intervention programs on men aged 50 or over and having had non-marital sexual behavior. A community-based intervention/experimental and based on individual level study was adopted. Stratified sampling method was used. 12 townships/streets in Fuyang district of Hangzhou were identified as intervention or control group (six research sites each). All of the subjects in the township (street) were included. The inclusion criteria of study objects would include men aged 50 or older who reported having unmarried sex in the last year. Estimated sample size was 290, with each 145 in the intervention group and the control group. All the intervention group participants were provided with a total of 4 intervention-related items (knowledge and education on AIDS prevention, information radiation and behavioral change, broadcast expert lectures), every 3 months, for 12 month, the main evaluation indicators would include: incidence of non-marital sex and commercial sex in the last year, condom use when having non-marital sex in the last episode. A total of 312 subjects were recruited. 300 of them completed the baseline study while 284 of them completed the follow-up survey. Among the subjects who had undergone the baseline study, the average age was (65.58±7.89), 71.33 were married or cohabiting with someone, 52.00 having had primary school education. After the implementation of intervention programs, the incidence of non-marital sex dropped to 59.42 (82/138) and the incidence of commercial sex dropped from 79.73 (118/148) to 55.07 (76/138). Condom use rate in the last non-marital sexual contact increased from 19.59 (29/148) to 51.22 (42/82). In the control group, the incidence of non-marital sex in the year before dropped to 74.66 (109/146) and the incidence of commercial sex dropped from 91.45 (139/152) to 72.60 (106/146). Rates of condom use during the last non-marital sexual contact dropped from 32.89 (50/152) to 31.19 (34/109). Statistically, there were significant differences appeared between the two groups on the incidence of non-marital sex in the past year ((2)=7.48, =0.008), the incidence of commercial sex in the last year ((2)=9.47, =0.003) and the rate of condom use in the last sex experience ((2)=7.83, =0.007). Results from this intervention study showed that: in the intervention group, both the incidence rates of non-marital or commercial sex had reduced, together with the increase of condom use in non-marital sex in the last sexual experience. Intervention strategies that involving knowledge and education on AIDS prevention, information radiation and behavioral change, broadcasting lectures by experts . were all proved effective.
评估艾滋病干预项目对50岁及以上有非婚性行为男性的效果。采用基于社区的干预/实验性个体水平研究。使用分层抽样方法。杭州市富阳区12个乡镇/街道被确定为干预组或对照组（各6个研究点）。纳入该乡镇（街道）的所有对象。研究对象的纳入标准为年龄在50岁及以上且报告去年有过非婚性行为的男性。估计样本量为290，干预组和对照组各145名。为干预组所有参与者总共提供4项与干预相关的内容（艾滋病预防知识与教育、信息传播及行为改变、播放专家讲座），每3个月一次，共12个月，主要评估指标包括：去年非婚性行为和商业性行为的发生率、最近一次非婚性行为时避孕套的使用情况。共招募了312名受试者。其中300名完成了基线研究，284名完成了随访调查。在接受基线研究的受试者中，平均年龄为（65.58±7.89）岁，71.33%已婚或与他人同居，52.00%接受过小学教育。干预项目实施后，非婚性行为发生率降至59.42%（82/138），商业性行为发生率从79.73%（118/148）降至55.07%（76/138）。最近一次非婚性接触时避孕套使用率从19.59%（29/148）增至51.22%（42/82）。在对照组中，前一年非婚性行为发生率降至74.66%（109/146），商业性行为发生率从91.45%（139/152）降至72.60%（106/146）。最近一次非婚性接触时避孕套使用率从32.89%（50/152）降至31.19%（34/109）。统计学上，两组在去年非婚性行为发生率（(2)=7.48，=0.008）、去年商业性行为发生率（(2)=9.47，=0.003）以及最近一次性行为时避孕套使用率（(2)=7.83，=0.007）方面存在显著差异。该干预研究结果表明：在干预组中，非婚性行为和商业性行为的发生率均有所降低，同时最近一次性行为中在非婚性行为时避孕套的使用有所增加。涉及艾滋病预防知识与教育、信息传播及行为改变、专家讲座播放等干预策略均被证明是有效的。
