Loss to follow up of pregnant women with HIV and infant HIV outcomes in the prevention of maternal to child transmission of HIV programme in two high-burden provinces in Papua New Guinea: a retrospective clinical audit.

INTRODUCTION: Despite early adoption of the WHO guidelines to deliver lifelong antiretroviral (ARV) regimen to pregnant women on HIV diagnosis, the HIV prevention of mother to child transmission programme in Papua New Guinea remains suboptimal. An unacceptable number of babies are infected with HIV and mothers not retained in treatment. This study aimed to describe the characteristics of this programme and to investigate the factors associated with programme performance outcomes. METHODS: We conducted a retrospective analysis of clinical records of HIV-positive pregnant women at two hospitals providing prevention of mother to child transmission services. All women enrolled in the prevention of mother to child transmission programme during the study period (June 2012-June 2015) were eligible for inclusion. Using logistic regression, we examined the factors associated with maternal loss to follow-up (LTFU) before birth and before infant registration in a paediatric ARV programme. RESULTS: 763 of women had records eligible for inclusion. Demographic and clinical differences existed between women at the two sites. Almost half (45.1%) of the women knew their HIV-positive status prior to the current pregnancy. Multivariate analysis showed that women more likely to be LTFU by the time of birth were younger (adjusted OR (AOR)=2.92, 95% CI 1.16 to 7.63), were newly diagnosed with HIV in the current/most recent pregnancy (AOR=3.50, 95% CI 1.62 to 7.59) and were in an HIV serodiscordant relationship (AOR=2.94, 95% CI 1.11 to 7.84). Factors associated with maternal LTFU before infant registration included being primipara at the time of enrolment (AOR=3.13, 95% CI 1.44 to 6.80) and being newly diagnosed in that current/most recent pregnancy (AOR=2.49, 95% CI 1.31 to 4.73). 6.6% (50 of 763) of exposed infants had a positive HIV DNA test. CONCLUSIONS: Our study highlighted predictors of LTFU among women. Understanding these correlates at different stages of the programme offers important insights for targets and timing of greater support for retention in care.

Youth-centred research to help prevent and mitigate the adverse health and social impacts of pregnancy amongst young Papua New Guineans.

Despite persistent international attention, adolescent pregnancy remains a major public health concern in low- and middle-income countries, like Papua New Guinea (PNG), where health inequities related to social and cultural norms, gender power imbalance, education and socio-economic deprivation affect young and unmarried women in particular. In PNG - where there is high adolescent fertility, high early childbearing and high maternal mortality ratio, and evidence of high rates of unintended pregnancy and abortion among young women - adolescent pregnancy is a policy priority. Yet there are no youth-specific sexual, reproductive and maternal health services or community-based outreach programmes. There is limited in-depth qualitative data on young women's and young men's experiences of pregnancy, the social contexts within which these pregnancies occur, young people's contraception practices and experiences with existing sexual, reproductive and maternal health services. These issues inhibit the design and delivery of youth-friendly health services and outreach support programmes that could prevent or mitigate adverse health and social outcomes associated with adolescent pregnancy. In this commentary article, we propose the need for novel youth-centred research to inform the development of policies, health services and outreach programmes that pay honest and respectful attention to young people's lived experiences of pregnancy. Whilst we focus on the situation in PNG, these ideas are relevant to diverse low resource settings where the harmful impacts of health inequities among young people persist and are particularly detrimental.
