Background: An estimated 96% of registered refugees in Iran are Afghan. Almost half of them are young women at the reproductive age. The adequate maternity care is crucial for healthy pregnancy. There is limited knowledge regarding the access and adequacy of maternity care among Afghan women in Iran. The reports from ministry of health (MOH) implicates higher prevalence of perinatal complication in Afghan population. This mainly attributed to the inadequate prenatal care in during pregnancy. Therefore, this paper explores the access and potential barriers to prenatal care among Afghan women in Iran.Methods: Using purposive convenient sampling, thirty pregnant Afghan women were recruited at three community health centers with the highest number of Afghan visitors in Tehran, the capital city of Iran. Data were collected through face-to-face interviews in Persian language using an interview guide. The interviewers were two bilingual Afghan graduate midwifery students. Each interview lasted for an hour. The interviews were transcribed into original language (Persian) and analyzed using content analysis. The MAXQD v.10 software was used in data analysis. The main themes were extracted grouping the similar codes and categories after careful consideration and consensus between the researchers.Results: The financial constraints and lack of affordable health insurance with adequate coverage of prenatal care services, particularly the diagnostic and screening tests, were the most frequent reported obstacles by Afghan women. In addition, personnel behavior, transportation issues, stigma and discrimination, cultural concerns, legal and immigration issues were also mentioned as the source of disappointment and inadequate utilization of such services.Conclusions: The findings of present study emphasize the necessity of available and most importantly, affordable prenatal care for Afghan women in Iran. Providing an affordable health insurance with adequate coverage of prenatal and delivery services, could reduce the financial burden, facilitate the access, and ensure the maternal and child health in this vulnerable population. The issues of fear and concern of deportation must be removed for at least illegal Afghan mothers to ensure their access to maternity care and improve the health of both mother and offspring.
