Tsogolo la Thanzi (TLT) was designed to study how young adults navigate sexual relationships and childbearing during a generalized HIV epidemic. TLT began in 2009 with a population-representative sample of 1,505 women and 574 men between the ages of 15 and 25 living in Balaka, southern Malawi, where regional adult HIV prevalence then stood at 15 percent. The first phase (2009-11) included a series of eight interviews, spaced four months apart. During this time, women's romantic and sexual partners enrolled in the study on an ongoing basis. A refresher sample of 315 women was added in 2012. Seventy-eight percent of respondents were re-interviewed in the second phase of TLT (2015), which consisted of follow-up interviews approximately 3.5 years after the previous interview (ages 21-31). At each wave, detailed information about fertility intentions and behaviors, relationships, sexual behavior, health, and a range of sociodemographic and economic traits was gathered by means of face-to-face surveys. Biomarkers for HIV and pregnancy were also collected. Distinguishing features include: a population-representative sample, closely spaced data collection, dyadic data on couples over time, and an experimental approach to HIV testing and counseling. Data are available through restricted data-user agreements managed by Data Sharing for Demographic Research (DSDR) at the University of Michigan.
Tsogolo la Thanzi（TLT）旨在研究在普遍存在 HIV 流行的情况下，年轻人如何处理性关系和生育问题。TLT 于 2009 年开始，在马拉维南部巴拉卡地区对年龄在 15 至 25 岁之间的 1505 名女性和 574 名男性进行了具有代表性的人口抽样调查，当时该地区成年人 HIV 流行率为 15%。第一阶段（2009-11 年）包括八次间隔四个月的访谈。在此期间，女性的浪漫伴侣和性伴侣不断加入研究。2012 年又增加了 315 名女性的刷新样本。在 TLT 的第二阶段（2015 年），78%的受访者接受了重新访谈，该阶段的随访访谈在之前的访谈之后大约 3.5 年进行（年龄 21-31 岁）。在每一波中，通过面对面调查收集了有关生育意愿和行为、关系、性行为、健康以及一系列社会人口和经济特征的详细信息。还收集了 HIV 和妊娠的生物标志物。其特点包括：具有代表性的人口抽样、紧密间隔的数据收集、关于夫妻随时间变化的对偶数据，以及对 HIV 检测和咨询的实验方法。数据可通过密歇根大学的人口研究数据共享（DSDR）管理的受限数据用户协议获得。
