Prevalence of anaemia and its associated factors among lactating mothers in eastern Sudan: a cross-sectional study

Background Lactating mothers are susceptible to anaemia. Little published data are available on lactational anaemia in Africa, including Sudan. This study was conducted to assess the prevalence of and associated factors for anaemia among lactating mothers in eastern Sudan. Methods A cross-sectional study was conducted and sociodemographic and clinical characteristics were gathered through a questionnaire. Results A total of 650 lactating mothers were included in the analysis. Their median age and parity were 28.0 y (interquartile range [IQR] 23.7-32.0) and 3.0 (IQR 2.0-4.0), respectively. Haemoglobin (Hb) levels ranged from 7.0 to 15.0 g/dL (median 11.2 [IQR 10.4-12.0]). Of the 650 lactating mothers, 442 (68.0%) had anaemia (Hb <12.0 g/dL). In multivariate analysis, lactating mothers with education less than the secondary level (adjusted odds ratio [AOR] 1.58 [95% confidence interval {CI} 1.05 to 2.37]) and lactating mothers who underwent caesarean delivery (AOR 1.74 [95% CI 1.17 to 2.58]) had a higher probability of being anaemic. Employment was associated to a lower frequency of anaemia (AOR 0.39 [95% CI 0.20 to 0.79]). Conclusions This study showed a high prevalence of anaemia among lactating mothers. Public health intervention activities designed towards education would be helpful to reduce anaemia.
