The effectiveness of interventions to involve men living with HIV positive pregnant women in low-income countries: a systematic review of the literature.

backgroundMale involvement (MI) along the continuum of HIV healthcare services has been promoted as a critical intervention in low-income countries and represents one of the reasons for dropout and low retention of women along the cascade of care. The present review aims to identify interventions adopted to improve MI across Antenatal Clinics (ANCs).

methodsFor this systematic review, we searched electronic databases, including Scopus, PubMed, Web of Science (from 2008 to 2018) in English language. We included all interventions explicitly aimed at involving partners in pregnant women's HIV continuum of care and we excluded studies performed in developed countries, not involving pregnant women. We followed the PRISMA checklist.

resultsWe identified a total of 1694 records and excluded 1651 after duplicates were removed and abstract eligibility assessments were performed. Forty-three full-text articles were screened, but only 12 studies were included. Recurrent intermediate outcomes were antenatal partner attendance rate and male HIV testing. We subdivided articles according to the type of intervention: single intervention (7) and multiple interventions (5). Among single interventions, two studies evaluated the use of an invitation letter sent via women to encourage male attendance to the ANC. Four Randomized Controlled Trials (RCTs) compared the invitation card (standard of care, SC) to word of mouth, information letter, home visit and invitation card plus partner tracing. The partner attendance rate was lower in SC than in the intervention arm in three RCTs: information letter (14.2% vs 16.2%), home-visit (39% vs 87%) and invitation card plus partner tracing (52% vs 74%). Home visit strategies seemed the most effective. One study evaluated words of encouragement adopted to trigger women to invite their partners. Among multiple interventions, the most effective strategies in terms of male attendance included health promotion through education and healthcare worker development. These interventions were more likely to be effective in promoting MI than single interventions.

conclusionsFrom the review emerges the importance of male involvement in HIV cascade for pregnant women in countries with a significant HIV incidence and the need to define more precise indicators for measuring MI.
