Kenya (2009): HIV/AIDS TRaC study evaluating condom use among youth aged 15-24 years in Kenya. Round Five.

The condom social marketing project is the largest component of the broader PSI/Kenya HIV/AIDS program with ultimate goal of reducing HIV prevalence rates among 15-24 year old youth. The program implements health education and behavior change communications that promote the benefits of abstinence and condom use, with emphasis on correct and consistent condom use among sexually active youth. Though varying strategies were applied to achieve the objectives of the intervention, this paper presen ts an assessment of the effectiveness of the most recent branded mass media campaign \"Trust the natural part of love\" in increasing opportunity, ability and motivation related perceptions and subsequently, condom use. This evaluation is based on five cross sectional survey rounds conducted in all provinces of Kenya except North Eastern. A baseline survey was carried out in 2001, and successive rounds in 2003, 2005, 2007, and 2009. A stratified, multi-cluster PPS sampling methodology was utilized to gather data at the household level in both urban and rural areas of Kenya.避孕套社会营销项目是PSI/肯尼亚艾滋病综合项目的核心组成部分，其终极目标为降低15至24岁青年群体的艾滋病病毒（HIV）现患率。本项目开展健康宣教与行为改变传播活动，宣传禁欲与使用避孕套的益处，重点强调性活跃青年需正确且持续地使用避孕套。尽管本干预项目采用了多种策略以达成既定目标，但本文针对最新的品牌化大众媒体宣传活动“信任爱情的本真面向”（"Trust the natural part of love"）展开效果评估，旨在考察其在提升机会感知、能力感知与动机感知等相关认知，以及后续避孕套使用行为方面的有效性。本次评估基于肯尼亚除东北省之外所有省份开展的五轮横断面调查，其中2001年完成基线调查，后续分别于2003、2005、2007及2009年完成四轮随访调查。研究采用分层整群按规模比例抽样（PPS, Probability Proportional to Size）方法，在肯尼亚城乡地区的家庭层面收集数据。
