Infant Human Immunodeficiency Virus-free Survival in the Era of Universal Antiretroviral Therapy for Pregnant and Breastfeeding Women: A Community-based Cohort Study From Rural Zambia.

ABSTRACT: BACKGROUND:Lifelong antiretroviral therapy (ART) is now recommended for all human immunodeficiency virus (HIV)-infected pregnant and breastfeeding women; however, few have described overall infant outcomes in this new era for the prevention of mother-to-child HIV transmission (PMTCT). METHODS:As part of an assessment of PMTCT program impact, we enrolled a prospective cohort study in 4 predominantly rural districts in Zambia. HIV-infected mothers and their newborns (?30 days old) were recruited and followed at 6 weeks, 6 months and 12 months postpartum; infant specimens were tested via HIV DNA polymerase chain reaction. In Kaplan-Meier analyses, we estimated overall infant HIV-free survival and then stratified by district, community and maternal ART use. We investigated the relationship between community-level 12-month, self-reported maternal ART use and infant HIV-free survival via linear regression. RESULTS:From June 2014 to November 2015, we enrolled 827 mother-infant pairs in 33 communities. At 12 months, small proportions of infants had died (2.8%), were HIV-infected (3.0%) or were lost to follow-up (4.3%). Overall, infant HIV-free survival was 99.0% [95% confidence interval (CI): 98.0%-99.5%] at 6 weeks, 97.5% (95% CI: 96.1%-98.4%) at 6 months and 96.3% (95% CI: 94.8%-97.4%) at 12 months. Women reporting ART use at enrollment had higher infant HIV-free survival than those who did not (97.4% vs. 89.0%, P = 0.01). Differences were noted at the district and site levels (P = 0.01). In community-level analysis, no relationship was observed between 12-month infant HIV-free survival and self-reported maternal ART use (P = 0.65). CONCLUSION:Although encouraging, these findings highlight the need for rigorous monitoring and evaluation of PMTCT services at the population level.

Project description:BACKGROUND:Breastfeeding provides health benefits to both women and children. The rationale behind an individual woman's decision to breastfeed or not can depend on several factors, either independently or in combination. The aim of the current study was to explore attitudes towards breastfeeding among pregnant women in Sweden who intend to breastfeed. METHODS:Eleven mothers-to-be, one of whom had previous breastfeeding experience, participated in the study. The women were interviewed either by telephone or face-to-face during late pregnancy, with the aim of exploring their attitudes towards breastfeeding. A semi-structured interview-guide was used, and the transcripts of the interviews were analyzed using thematic analysis. The social ecological model of health is the theory-based framework underpinning this study. The model provides a comprehensive approach to understanding the factors that influence breastfeeding intention. RESULTS:When interviewed during pregnancy, women described breastfeeding as a balancing act between societal norms and personal desires. The women perceived a societal pressure to breastfeed, however it was accompanied by boundaries and mixed messages. This perceived pressure was balanced by their own knowledge of breastfeeding, in particular their knowledge of other women's experience of breastfeeding. When envisioning their future breastfeeding, the women made uncertain and preliminary plans, and negotiated the benefits and drawbacks of breastfeeding. There was a wish for individual breastfeeding support and information. CONCLUSIONS:Pregnant Swedish women perceive their future breastfeeding as a balancing act between societal norms and personal desires. These findings suggest that while discussing breastfeeding during pregnancy, it could be of interest to collect information from pregnant women on their knowledge of breastfeeding and from where they have gained this knowledge, since stories from family and friends may make them question their own capacity to breastfeed. A thorough review of the woman's experiences and attitudes of breastfeeding is important in order to offer the best evidence-based breastfeeding support. TRIAL REGISTRATION:Ethical approval for the study was obtained from the Regional Ethical Review Board in Uppsala (Dnr: 2017/256).
