Improved knowledge and practices among end-users of mother-to-child transmission of HIV prevention services in rural Zimbabwe

To evaluate the influence of a prevention of mother-to-child transmission of HIV advocacy and mobilization campaign on awareness and knowledge levels within the community. We used a knowledge, attitudes and practices survey to collect baseline data in November 2002 and again in July 2004 for evaluation purposes. A total of 351 women attending healthcare services were interviewed each time. The proportion of women aware of the service increased from 48.0% in 2002 to 82.8% in 2004 (OR = 4.9, 95% CI 3.3-7.3, P = 0.001). Exclusive breastfeeding was identified as a mother-to-child transmission risk factor by 27.1% in 2002 and by 55.8% of respondents in 2004 (OR = 2.9, CI 2.1-4.2, P = 0.001). Although most interviewees agreed that the prevention of sexual transmission of HIV was the best strategy for prevention of mother-to-child transmission of HIV (88.3% in 2002 and 96.4% in 2004), few reported having ever used a male condom (24.8% in 2002 vs. 29.8% in 2004, P = 0.16). Prevention of mother-to-child transmission of HIV strategies at both individual and community level were still insufficiently understood and applied. Targeted educational messages and communication for social change need to be combined. Knowledge, attitudes and practices surveys can be used to monitor programme progress.
