Background: Widely spread throughout the world, folate and iron deficiencies are risk factors for many diseases. However, contrary to iron deficiency and anemia, which have been documented in depth, the prevalence of folate deficiency among women has not been well-studied. Objective: The aim of this study is to determine the prevalence of folate deficiency and anemia and their association among Senegalese women of reproductive age. Methods: A national cross-sectional survey using a stratified 2-stage cluster sampling was conducted. Data were collected from 1012 women (aged 15-49 years). Plasma folate and hemoglobin (Hb), as well as protein markers of subclinical infections, were equally measured. Results: The mean folate concentration was 8.50 nmol/L (8.16-8.85 nmol/L), and 54.8% of the women were folate deficient (<10 nmol/L). Plasma folate concentration of rural women (7.27 nmol/L [6.89-7.68 nmol/L]) and urban women (10.45 nmol/L [9.88-11.05 nmol/L]) was significantly different (P < .0001), the highest concentration being observed in women living in Dakar, the capital of Senegal. The breastfeeding women showed lower plasma folate concentration compared to nonbreastfeeding ones: 6.97 nmol/L (6.37-7.63 nmol/L) versus 9.03 nmol/L (8.61-9.46 nmol/L). Overall, 27% of the women were suffering from inflammation/infections. Mean Hb concentration was 116.86 (1.18) g/L, and 47.63% of the women involved in the study were anemic (pregnant women Hb <110 g/L; nonpregnant Hb <120 g/L). Also, a positive and significant correlation was found between plasma folate and Hb concentrations (r = .07; P = .0167). Conclusions: This study showed a high prevalence of folate deficiency and anemia among Senegalese women (15-49 years), particularly those living in rural settings and breastfeeding women.
