Project Summary The goal of this research is to inform the development of adolescent health programs through understanding the development and trajectories of empowerment over the course of adolescence, among girls and boys, and quantifying how this process influences sexual and reproductive health behaviors and outcomes. The proposed project will use four waves of longitudinal data, collected annually from a sample of 2,842 adolescents, aged 10-14 years at enrollment, in Kinshasa, Democratic Republic of Congo. Learnings from this research will inform interventions designed to improve empowerment and affect long-term health trajectories of adolescents as they transition into adulthood. The specific aims are: 1. Establish how agency evolves over time for boys and girls. Using each sub-scale of agency (Freedom of Movement, Voice, Decision-Making) and a combined agency score across all domains, we will conduct latent growth curve modeling to assess how individual scores change over time and explore how these trajectories differ by gender. 2. Identify significant socio-ecological factors (opportunity structures) that influence trajectories, by gender. We will use latent growth curve modeling to explore the effect of time varying socio- ecological factors (including individual, family, peer, and neighborhood factors) that predict changes in total agency and within each agency sub-scale to assess how opportunity structures influence the development of agency over time. 3. Assess the association of agency in very young adolescence with sexual and reproductive health behaviors in later adolescence. We will use Cox Proportional Hazard models to assess the relationship of each domain of agency with age at sexual debut and logistic regression to evaluate contraceptive behavior, and volitional sex, assessing the effect of both baseline levels of agency and change over time in its impact on sexual and reproductive health behaviors. The study is a secondary data analysis of longitudinal data from the Global Early Adolescent Study. Aims 1 and 2 will employ stratified latent growth curve models to explore how three previously validated measures of agency change over time and by gender. Aim 3 will employ Cox Proportional Hazards models and multivariable logistic regression models to estimate the relationship between empowerment and key sexual and reproductive health behaviors and outcomes.

项目摘要 这项研究的目的是通过理解来告知青少年健康计划的发展 在青春期，男孩和男孩中，赋权的发展和轨迹，以及 量化此过程如何影响性和生殖健康行为和结果。这 拟议的项目将使用四波纵向数据，每年从2,842的样本中收集 刚果民主共和国金沙萨（Kinshasa）入学10至14岁的青少年。从中学习 研究将为旨在提高赋权和影响长期健康轨迹的干预措施提供信息 青少年过渡到成年时。 具体目的是： 1。建立代理商如何随着时间的流逝而演变为男孩和女孩。使用每个代理商 （运动自由，声音，决策）以及在所有领域的合并代理分数，我们 将进行潜在的增长曲线建模，以评估个体得分如何随时间变化而 探索这些轨迹如何因性别而异。 2。确定影响轨迹的重要社会生态因素（机会结构）， 由性别。我们将使用潜在的增长曲线建模来探索时间变化的社会效果 生态因素（包括个人，家庭，同伴和邻里因素）预测变化 全部代理机构和每个代理商中的尺度，以评估机会结构如何影响 随着时间的推移发展代理。 3。评估非常年轻的青春期代理人与性和生殖的关联 青春期后期的健康行为。我们将使用COX比例危害模型来评估 代理商的每个领域与年龄在性亮相和逻辑回归中的关系以评估 避孕行为和自愿性，评估了基准代理水平和 随着时间的推移对性和生殖健康行为的影响随着时间的变化。 该研究是全球早期青少年研究的纵向数据的二级数据分析。目标1 2将采用分层的潜在生长曲线模型来探讨三个先前验证的措施如何 代理商会随着时间和性别而改变。 AIM 3将采用COX比例危害模型，并且 多变量逻辑回归模型，以估计赋权与关键性关系之间的关系 以及生殖健康行为和结果。
