RESUMEN
Background: Decision-making in choosing and using maternal health care among different care-seeking options is a complex process influenced by multilevel factors. Existing evidence on maternal health care-seeking behaviour stems primarily from cross-sectional studies with limited information. Therefore, we designed a cohort study to better understand the decision-making process in antenatal care (ANC) seeking. Methods: We conducted this mixed-methods study among pregnant women at <27 weeks of gestation in a poor urban area (n = 1320) and a typical rural area of Bangladesh (n = 1239) whom we followed up till eight weeks after delivery. In view of quantitative methods, we interviewed all enrolled women 5-6 times four weeks apart. For the qualitative approach, we conducted 70 case studies in the urban area and 46 in the rural area by interviewing the participants and their close family members. Results: In the urban area, about one-third of the pregnant women (38.4%) sought ANC at non-governmental organisations, and nearly an equal proportion went to public facilities (36.6%). In both the situations, women preferred facilities with one-stop services at a reasonable cost. In contrast, the lack of readiness in public facilities of the rural area pushed women (77.8%) toward private facilities for ANC. The reputation of the facilities, availability of skilled care providers, diagnostic tests, and ultrasonography services therein were the key influencing factors in the participants' decisions to seek ANC services from specific facilities. Conclusions: The availability of one-stop services was a key factor for participants' choosing of a facility for ANC. For the urban setting, there is a need to establish large public facilities with one-stop service provision in different zones, along with supporting non-governmental organisations in poor areas. For the rural setting, there is an urgent need to strengthen ANC service provision in public facilities at the community- and the sub-district level to redirect women from the private to the public sector to ensure low cost, quality services.
