固定效应模型对知情选择政策影响的再验证——以已婚育龄个体避孕措施选择的变化为例

利用固定效应模型对1988-2001年全国计划生育/生殖健康调查数据进行了再次分析,以量化考察知情选择政策对中国已婚育龄个体避孕措施选择的影响。研究发现,知情选择与已婚育龄个体避孕措施选择的变化之间呈现一定的因果关联。知情选择导致了育龄个体避孕措施选择的改变,表现为短效自控型避孕措施选择的可能性随着知情选择的开展在逐步升高,而长效医控型避孕措施选择的可能性在逐步降低。     

Effects of Brief Messages About Antiretroviral Therapy and Condom Use Benefits Among Black and Latino MSM in Three U.S. Cities

This pilot study examined effects of HIV prevention messages about self and partner benefits of antiretroviral therapy (ART) and condom effectiveness on increased intentions for behavior change. Data were from Messages4Men, a study examining prevention messages among 320 HIV-positive and 605 HIV-negative Black and Latino MSM. Men completed a computer-based assessment after message exposure, and multivariable models controlled for risky sex and demographics. A majority of HIV-positive men reported increased intentions for ART use; 22% reported partner benefit information was new. HIV-positive men with a detectable viral load had significantly greater adjusted odds of reporting intentions for ART use. Over half of HIV-negative MSM reported ART benefit information was new, and 88% reported increased intentions to discuss ART use with infected partners. Black MSM anticipated they would increase condom use in response to the self and partner benefit messages. Tailored messages on benefits of ART are needed for MSM.
