Effects of the Waya Intervention on Marital Satisfaction and HIV Risk Behaviors in Western Kenya: A Pre-Post Study Design.

Poor marital satisfaction is associated with high-risk sexual behavior and HIV transmission. We tested whether a counselor-led couple education and counseling intervention dubbed Waya (paternal aunt) would improve marital satisfaction and reduce HIV risk behavior among married couples in Kisumu County, western Kenya. In a pre-post design, we enrolled 60 heterosexual married couples at high risk for HIV to undergo five 1-h couple education and counseling sessions over 56 days. We collected self-reported data on marital satisfaction, the number of sex partners, and condom use with extramarital partners at pre- and post-intervention visits. We used Wilcoxon and McNemar tests to examine the association of our intervention with marital relationship satisfaction and reduction in HIV risk sexual behavior. The intervention was associated with marital relationship satisfaction score improvement from a median of 5 (interquartile range [IQR], 4-5) to 6 (IQR, 6-7) among men and 4 (IQR, 3-5) to 6 (IQR, 5-6) among women (p < .01). The intervention was also associated with reducing HIV risk sexual behaviors depicted by a reduction in the number of sex partners in the past one month and an increase in consistent extramarital condom use. The number of sex partners reduced from a median of 2 (IQR, 1-2) to 1 (IQR, 1-2) and consistent extramarital condom use increased from 4% at baseline to 56% among men. Our intervention was associated with improvements in marital relationship satisfaction and reductions in HIV high-risk behaviors necessary for achieving epidemic control in HIV hotspots such as fishing communities in western Kenya.
