Tsogolo La Thanzi 2 (TLT-2), Malawi, 2015 [Healthy Futures]

Tsogolo la Thanzi (TLT) is a longitudinal study in Balaka, Malawi designed to examine how young people navigate reproduction in an AIDS epidemic. Tsogolo la Thanzi means "Healthy Futures" in Chichewa, Malawi's most widely spoken language. New data is being collected to develop better understandings of the reproductive goals and behavior of young adults in Malawi -- the first cohort to never have experienced life without AIDS. To understand these patterns of family formation in a rapidly changing setting, TLT used a unique approach: an intensive longitudinal design where respondents are interviewed every fourth month at TLT's centralized research center. Data collection began in May of 2009 and was completed in December 2011 (waves 1-8), with an additional Refresher Sample (wave 9) fielded in early 2012 as a form of addressing study attrition and creating the ability to compare the "treatment" effect of survey participation on respondents who participated in waves 1-8. This study contains data collected from a follow-up survey referred to as Tsogolo la Thanzi 2 (TLT-2), which was fielded between June and August of 2015 and created to assess changes on a longer time-horizon. TLT-2 covers many of the same topics found in the original TLT multi-wave project such as: relationships, religion, HIV/AIDS, politics, family composition, mental health, sex and protection, pregnancy, marriage, sexually transmitted diseases, future expectations, school enrollment status, goods purchased/received, and diet. Modules specific to TLT-2 include: conditionalities, technology, and time use.

《健康未来》（Tsogolo la Thanzi，简称TLT）是一项在马拉维巴兰卡地区开展的纵向研究，旨在探究艾滋病疫情背景下年轻人如何应对生育相关议题。Tsogolo la Thanzi在马拉维使用最广泛的奇切瓦语中意为“健康未来”。该研究目前正在采集新数据，以更深入地理解马拉维年轻成年人的生育目标与行为——他们是首批从未经历过无艾滋病时代的人群队列。
为厘清快速变迁环境中的家庭组建模式，TLT采用了独具特色的密集型纵向研究方案：每四个月于TLT的集中研究中心对受访者开展一次访谈。数据采集工作始于2009年5月，至2011年12月完成（共完成8轮调查，即第1至8波）；2012年初额外开展了一轮补充样本调查（第9波），以解决研究失访问题，并可对比分析参与第1至8波调查的受访者所受的调研参与“处理效应”。
本数据集包含2015年6月至8月间开展的追踪调查“Tsogolo la Thanzi 2（TLT-2）”所采集的数据，该调查旨在从更长时间跨度评估相关议题的变化情况。TLT-2涵盖了原始TLT多轮研究项目中的多数核心主题，包括：人际关系、宗教信仰、人类免疫缺陷病毒/获得性免疫缺陷综合征（HIV/AIDS）、政治态度、家庭构成、心理健康、性行为与防护措施、妊娠、婚姻、性传播疾病、未来预期、在校就读状态、物品购置/受赠情况以及饮食状况。TLT-2的专属研究模块则包括：条件性议题、技术应用与时间使用情况。
