Determinants of antenatal care use in nine sub-Saharan African countries: a statistical analysis of cross-sectional data from Demographic and Health Surveys

Abstract

Objective To explore the factors associated with antenatal care (ANC) visits. Design A secondary data analysis from cross-sectional studies was conducted. Setting Sub-Saharan Africa. Participants 56 002 women aged 15–49 years in Ghana (3224), Kenya (10 981), Malawi (9541), Namibia (2286), Rwanda (4416), Senegal (6552), Tanzania (5536), Uganda (7979) and Zambia (5487) were analysed. Outcomes 4 + ANC visits. Results Overall, 55.52% (95% CI: 55.11% to 55.93%) of women made 4 + ANC visits. The highest 4 + ANC visits were in Ghana (85.6%) and Namibia (78.9%), and the lowest were in Senegal (45.3%) and Rwanda (44.5%). Young women 15–19 years had the lowest uptake of 4 + ANC visits. Multivariable analysis indicated that the odds of 4 + ANC visits were 14% lower among women from rural areas compared with those living in towns (adjusted OR (AOR) 0.86; 95% CI: 0.81 to 0.91). This difference was significant in Kenya, Malawi, Senegal and Zambia. However, in Zambia, the odds of 4 + ANC visits were 48% higher (AOR 1.48; 95% CI: 1.2 to 1.82) among women from rural compared with urban areas. Women with higher educational level had more than twofold higher odds of 4 + ANC visits in seven of the nine countries, and was significant in Kenya, Malawi, Rwanda and Zambia. Compared with the poorest household wealth category, odds of 4 + ANC visits increased by 12%, 18%, 32% and 41% for every 20% variation on the wealth quantile. Women in their first-time pregnancy had higher odds of 4 + ANC visits compared with others across all countries, and women who had access to media at least once a week had a 22% higher probability of 4 + ANC visits than women who had no access to media (AOR 1.22, 95% CI: 1.15 to 1.29). Conclusion The number of ANC visits was considered to be inadequate with substantial variation among the studied countries. Comprehensive interventions on scaling uptake of ANC are needed among the low-performing countries. Particular attention should be given to women of low economic status and from rural areas.
