" I…Tell Her Not to Take Medicines ": Understanding Engagement in the Prevention of Mother to Child Transmission (PMTCT) Care Continuum through the Socio-Ecological Model.

With ten percent of the world's children living with Human Immunodeficiency Virus (HIV/ AIDS) in India, achieving elimination of parent/mother to-child transmission (EPTCT/EMTCT) is far away. Timely initiation and optimal adherence to the prevention of parent/mother to child transmission (PPTCT/PMTCT) may reduce new paediatric HIV infections to zero. This qualitative study applies the Socio-ecological Model (SEM) to understand country, region and context-specific factors influencing mothers' engagement in the PMTCT care continuum. Maximum variation sampling and saturation tenets determined the sample size. An in-depth interview guide based on SEM "a priori" and emerging themes captured narratives of the parental dyad. The translated and transcribed audio records were coded by direct content analysis method, both manually and with Atlas Ti software. The coding reports were discussed for consensus and final analysis. Male partner, peers, community health workers (CHWs), hope for healthy baby, knowledge about HIV and preventive services, free anti-retroviral therapy, transportation and the early infant diagnosis (EID) tool influenced PMTCT care continuum. Testing and referral policies of the private sector facilitated internalized or self-stigma. Future interventions should seek to develop pregnant women's support system by engaging male partners, peers, and CHWs. Strategies addressing private sector and community awareness about freely available HIV prevention and care programs may enable optimal PMTCT utilization.
