不同强度干预对建筑工人艾滋病、性病知识的影响

目的]了解不同强度干预措施对建筑工人艾滋病、性病知晓率的影响,为有效开展建筑工地艾滋病、性病预防干预工作提供依据。方法]选择上海市徐汇区6个工地的620名工人进行面对面问卷调查,并在不同的建筑工地分别施加不同强度的干预措施,观察工人艾滋病性病相关知识的变化情况。结果]高、中、低度干预组两次随访艾滋病、性病相关知识水平都有明显上升;HIV传播途径的知晓率较高,非HIV传播途径的知晓率较低,但后者干预后知识增长速度远远快于前者;艾滋病传播途径知识得分变化趋势为低度干预组缓慢升高、中度干预组升高后速度趋缓、高度干预组快速升高后保持较高水平。结论]建筑工人的艾滋病、性病知识水平得到显著提高;干预措施强度越高,近期效果越明显;高度干预措施远期效果明显,而低度和中度干预措施远期效果相近;三种不同强度的干预方式对预防艾滋病、性病均效果良好,在实际工作中可视具体条件选定干预措施;本研究的经验可为相似人群的研究提供参考和借鉴。

Influence of Different Intensity Interventions on Knowledge of AIDS and STD among Construction Workers

Objective] To investigate the influence on the knowledge of aquired immune deficiency syndrome（AIDS）/ sexually transmitted diseases（STD） among construction workers after receiving different intensity intervention measures and to provide evidence for implementing AIDS/STD prevention and intervention more effectively.Methods] A face-to-face questionnaire survey was conducted among 620 construction workers randomly selected from 6 sites in Xuhui District of Shanghai.Meanwhile different intensity intervention measures were delivered,and the changes of AIDS/STD knowledge were evaluated.Results] AIDS/STD knowledge among construction workers in high-,mid-and low-intervention groups increased obviously in 2 follow-up visits.The awareness rate of HIV transmission routes was higher than that of non-transmission routes,but the latter increased faster than the former.The trends of the knowledge score of HIV transmission routes increased slowly in low-intervention group,increased and then slowed down in mid-intervention group,and increased quickly and then kept steady in high-intervention group.Conclusion] AIDS/STD knowledge among construction workers has increased obviously after receiving intervention measures.The stronger the intervention measure is,the more obvious the recent effect is.The long-term effects of high level intervention are more obvious and those of the other two are near.These three different intensity intervention measures have all functioned well on AIDS/STD prevention,and can be used depending on specific working conditions.Our study can provide reference to other studies on similar populations.
