Effect of Nurse-Led PMTCT Health Education on HIV Disclosure among HIV-Positive Women in Mombasa County: A quasi-experimental study

Abstract

Background: This study investigated the impact of nurse-led PMTCT (Prevention of Mother-toChild Transmission) health education on enhancing HIV status disclosure among HIVpositive women in Mombasa County, Kenya. HIV status disclosure is crucial for the prevention of mother-to-child transmission and the overall well-being of affected individuals and their families.

Methods: A quasi-experimental design was employed, with participants divided into an intervention group of 107 receiving nurse-led PMTCT health education and a control group of 107 receiving standard care. Demographic information, knowledge, attitudes, and practices related to HIV status disclosure were collected at baseline and post-intervention phases. Descriptive statistics were computed and a chi-square test was used to compare the level of self-disclosure of HIV status to sexual partners across the groups. Difference in differences (DID) analysis was used to evaluate the effectiveness of the intervention. Results: The study initially found that at baseline, 60.4% of HIV-positive women in the control group did not disclose their status to sexual partners, compared to 55.4% in the intervention group. However, there was no significant difference between the two groups at this stage. In the end-line survey, the control group had 64% non-disclosure, while the intervention group showed a significant improvement, with only 20% not disclosing. Chi-square analysis revealed a substantial difference (p < 0.001) in disclosure rates between the intervention and control groups. Additionally, a Difference-in-Differences (DID) analysis indicated a significant improvement in self-disclosure (23.1% net intervention effect, p < 0.0001). Overall, the nurse-led health education intervention notably increased HIV status disclosure among HIV-positive women in selected Mombasa County health facilities.

Conclusion: Nurse-led PMTCT education enhances HIV disclosure in Mombasa County, improving PMTCT outcomes and curbing mother-to-child transmission. Tailored interventions are vital in addressing HIV challenges in diverse contexts.
