Correlates of antenatal care usage among adolescent mothers in Nigeria: a pooled data analysis.

This study examined selected correlates of timing and frequency of antenatal care visits among adolescent mothers aged 15-19 in Nigeria. Data from the women's recode dataset of the Nigeria Demographic and Health Surveys between 2003 and 2018 were pooled, with a sample size of 4,775. Multivariate data analysis was carried out using binary logistic regression. It was found that being educated (aOR = 1.54; CI = 1.14-2.08; aOR = 1.64; CI = 1.11-2.42); higher wealth status (aOR = 1.88; CI = 1.45-2.43; aOR = 1.92; CI = 1.33-2.76); contributing to health decision-making (aOR = 1.44, CI = 1.15-1.81); having an educated partner (aOR = 1.73; CI = 1.31-2.30; aOR = 2.44; CI = 1.84-3.25); and living in the South West region (aOR = 3.68; CI = 1.72-7.87) were associated with higher complete antenatal care utilization. Having difficulty getting permission to go to the health facility (aOR = 0.75, CI = 0.57-0.99) and with the distance to the health facility (aOR = 0.61, CI = 0.49-0.75) were associated with lower likelihood of ANCU. Respondents with secondary and higher education were more likely to start ANC early (aOR = 1.57, CI = 1.05-2.34), but Muslim mothers (aOR = 0.61, CI = 0.40-0.32) and those living in the North West (aOR = 0.43, CI = 0.26-0.71), South-South (aOR = 0.30, CI = 0.17-0.53) and South West (aOR = 0.29, CI = 0.12-0.69) were less likely to begin ANC early. Therefore, interventions to increase antenatal care must be region-specific, and focus attention on lower status adolescent mothers with less autonomy.
