[Show abstract][Hide abstract] ABSTRACT: This paper describes the experiences and concerns of women participating in a short-term AZT intervention feasibility study to prevent mother-to-child HIV transmission at three sites in India. The study used qualitative methods to examine the experiences of 31 women during late pregnancy, delivery and at post-natal visits. It also elicited the perspectives of 19 healthcare providers. Frequent visits required during late-pregnancy and the post-natal period presented concerns for the women in the study. Women's understanding of the long-term implications of participating in the intervention study was poor, and living with uncertainty about the HIV status of the newborn was a major concern. The provision of psychosocial support is essential in future intervention studies and should be incorporated on an ongoing basis. Networking with women-centred support groups may be helpful in enabling women to gain the long-term benefits of this type of intervention.
