Tsogolo La Thanzi (TLT): Ninth Wave, Malawi, 2012 [Healthy Futures]

Résumé 0

Tsogolo la Thanzi (TLT) is a longitudinal study in Balaka, Malawi designed by Jenny Trinitapoli and Sara Yeatman 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. The TLT research team has collected data to better understand the reproductive goals and behavior of young adults in Malawi. This is the first cohort to never have experienced life without AIDS. To understand these patterns of family formation in a rapidly changing setting, TLT used the following 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). In addition, a Refresher Sample (wave 9) was fielded in early 2012 as a form of addressing study attrition but also to create the ability to compare the "treatment" effect of survey participation on respondents who participated in waves 1-8. The Refresher Sample includes 315 women who were sampled but not enrolled at wave 1 (baseline), and thus only entered the study in 2012. Furthermore, to assess changes on a longer time-horizon, a follow-up survey referred to as TLT-2 was fielded between June and August of 2016 which includes all baseline and comparison sample women, plus all men ever-interviewed for the study. Each of waves 1-8 are comprised of three data files: women, random men, and male partners. However, wave 9 includes only a sample of women who did not enroll in baseline (N=315). Topics covered across all waves include 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. Of the occasional modules, those included at wave 9 [Refresher Sample] are: background, residency and migration, travel and parent information. Otherwise, the comparison sample is more similar to the baseline wave, relative to other rounds of data collection.
