About
The purpose of this study is to test the efficacy of an innovative, culturally relevant, community-based peer group intervention to increase young rural Malawian women's preconception behaviors to optimize their reproductive health. The study uses a longitudinal, two group (two-arm) design with a delayed control group.
Full description
Maintaining optimal reproductive health in the context of high HIV prevalence is a serious dilemma facing young women in Malawi and other high HIV prevalence countries. Optimal reproductive health requires practicing preconception behaviors to promote overall health including avoiding HIV infection. These healthy preconception behaviors include: practicing safer sex (abstaining or using condoms) to prevent sexually transmitted infections (STIs), including HIV infection; obtaining treatment for STIs; maintaining good health habits such as diet, exercise and avoiding substance use; using an effective family planning method to prevent unintended pregnancy; and having an HIV test periodically and with the partner when conception is intended. However the Malawi Demographic and Health Survey provides evidence that few women ages 15-20 in Malawi currently practice these healthy preconception behaviors. Currently, no programs in Malawi offer an integrated approach to optimal reproductive health.
To fill this gap, this study developed an innovative, culturally relevant, community-based peer group intervention to increase young rural Malawian women's preconception behaviors to optimize their reproductive health. The intervention is called Mzanga Samala Moyo Wako ([Mzanga] Sharing Responsibility for Pregnancy Planning and HIV Prevention). Mzanga builds on the investigators' previous research in Malawi, which tested a culturally relevant HIV prevention peer group intervention that changed HIV prevention-related knowledge, attitudes, and safer sex behaviors for rural adults and adolescents. This study integrated that prior HIV prevention content with new content on maintaining health, family planning, and preconception HIV testing.
The purpose of this study is to test Mzanga's efficacy using a longitudinal, two group (two arm) design: intervention group and delayed control group. Because Mzanga is expected to diffuse widely, we randomize at the community rather than the individual level. Eighteen geographically separate rural communities stratified by size and distance from the main paved road and then randomly assigned to Mzanga or the delayed control condition. We implement Mzanga in 9 waves. A final sample of 345 per group after attrition provides adequate power (80%) to detect small-to-medium effects. After baseline data collection, the Mzanga group receives the eight-session intervention. Outcomes are measured at 9 months post-baseline (6 months post-intervention), followed by a booster session for the Mzanga group, and final evaluation at 15 months post-baseline. After the 15-month data collection, Mzanga is offered to the delayed control group.
The study aims and hypotheses are:
Aim 1. To test the efficacy of the Mzanga intervention for improving reproductive health outcome mediating and behavioral variables for Malawian rural young women at 9 and 15 months post-baseline.
H1.Controlling for baseline differences and group effects, compared to the delayed control group, the intervention group will show more positive mediating and behavioral outcomes:
- Practice safer sex,
- Obtain prompt treatment for STI symptoms;
- Maintain good health habits (diet, exercise, substance use);
- Use an effective family planning method except when pregnancy is intended;
- Have an HIV test periodically, with partner when conception is intended; and
- More positive scores for the mediating variables of knowledge, attitudes, perceived norms, self-efficacy, and intentions for each of these behaviors.
Aim 2. To test a theoretical model of the mechanisms through which the Mzanga intervention changes preconception health behaviors of young women in rural Malawi.
H2. Mzanga's effects on healthy preconception behaviors (a-e above) will be mediated by knowledge, attitudes, perceived norms, self-efficacy, and intention scores.
