Summary

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.

Study Purpose

The Tsogolo La Thanzi project surveyed females about their reproductive behavior in Balaka, Malawi. The TLT project sought to determine prevalence of STDs (sexually transmitted diseases), characteristics of respondents' pregnancies, and marriage and family history. The study additionally interviewed the male partners of these women and also random men of the same age, asking both groups similar questions.

Study Design

Tsogolo La Thanzi (TLT) is an ongoing longitudinal study of young Malawians living within 7-kilometer radius of Balaka. The data was collected during face-to-face interviews from a simple random sample.

This particular study is a follow-up to the original TLT multi-wave project.

Sample

Of the original 'core sample' from TLT, 1200 women and 407 men were reinterviewed in 2015. An additional 253 women from the refresher sample that immediately followed wave 8 were also re-interviewed in 2015, for a total of 1453 women in the TLT-2 dataset. Again in this phase of the study, women were given tokens to share with their sexual and romantic partners, allowing these men to enroll in the study. Male partners from TLT were only included in TLT-2 if they were still in a relationship with a female respondent (N=311). Women recruited 262 new, current male partners using tokens (total N=573).

Women and male partners who appear in both the TLT and TLT-2 datasets can be followed longitudinally across study phases using a single, unique identifier (RESPID). Respondent identifiers are coded to indicate to which part of the sample the respondent belongs. Random men who were enrolled as part of the core sample in 2009 have RESPIDs that begin with "5". Male partners enrolled during waves 1-8 of TLT were assigned RESPIDs that begin with "6". Male partners who enrolled for the first time in TLT-2 have RESPIDs that begins with "7".
