Antenatal Care Attendance, a Surrogate for Pregnancy Outcome? The Case of Kumasi, Ghana

Antenatal care (ANC) has been shown to influence infant and maternal outcomes. WHO recommends 4 ANC visits for uncomplicated pregnancies. However, pregnant women in Ghana are required to attend 8–13 antenatal visits. We investigated the association of ANC attendance with adverse pregnancy outcomes (defined as low infant birth weight, stillbirth, preterm delivery or small for gestational age). A quantitative cross-sectional study was conducted on 629 women, age 19–48 years who presented for delivery at two selected public hospitals and 16 traditional birth attendants from July to November 2011. Socio-demographic and antenatal information were collected using a structured questionnaire. ANC attendance, medical and obstetric/gynecological history were abstracted from maternal antenatal records. Data were analyzed using Chi square and logistic regression. Twenty-two percent of the women experienced an adverse outcome. Eleven percent of the women attended <4 ANC visits. In an unadjusted model, these women had an increased likelihood of experiencing an adverse outcome (OR 2.27; 95 % CI 1.30–3.94; p = 0.0038). High parity (>5 children) was also associated with adverse birth outcomes. Women screened for syphilis or use of insecticide-treated bed nets had a 40 and 36 % (p = 0.0447 and p = 0.0293) reduced likelihood of experiencing an adverse pregnancy outcome respectively. After adjusting for confounders, attending <4 antenatal visits was associated with adverse pregnancy outcome compared with ≥4 ANC visits (Adjusted OR 2.55; 95 % CI 1.16–5.63; p = 0.0202). Attending <4 antenatal visits and high parity were associated with adverse pregnancy outcomes for uncomplicated pregnancies.
