Prevalence, Aetiology, Maternal and Neonatal Outcome of Term Mothers with Anaemia, Presenting to a Tertiary Care Unit for Confinement in Sri Lanka

Objective: To describe the proportion of women presenting with undiagnosed anaemia at confinement and to explore associations between anaemia and socio economic factors, dietary pattern and compare maternal and neonatal outcome among term mothers with anaemia compared to non-anaemic pregnant women at a tertiary care centre in Sri Lanka. Method: A comparative cross-sectional study was performed by recruiting anaemic and non-anaemic term mothers who delivered at the Teaching Hospital Peradeniya during the period March 2018-March 2019. Pregnant mothers whose haemoglobin level was less than 10.5 g/dl were considered as anaemic and compared with the mothers whose haemoglobin level was above this level. With written consent, demographic data, etiological factors, maternal and neonatal outcomes of term mothers were evaluated by an interview and blood samples were withdrawn to carry out anaemia related investigations. Results: Among 2854 pregnancies, a total of 234 (8.19%) term pregnant mothers were anaemic and they were and compared with 199 non-anaemic mothers. Out of the anaemic mothers (Hb < 105 g/l), 133 (56.76%) had moderate anaemia, 100 (42.79%) had mild anaemia and 1 mother (0.45%) had severe anaemia. Low monthly family income was significantly associated with the incidence of anaemia. Anaemia was also associated with low weekly consumption of red meat (OR 8.994; 95% CI, 5.74 - 14.09, p < 0.05) and high weekly tea intake (OR 0.217; 95% CI 0.144 - 0.327, p < 0.05). Among anaemic mothers, 215 (67.44%) had low serum ferritin (<30 ng/mL) while most of them were diagnosed with iron deficiency anaemia (58.24%) (n = 113) based on haemoglobin. Most anaemic mothers had undergone elective caesarean section (46.26%) while vaginal deliveries (33.33%) were common among non-anamic group. Conclusions: A moderate prevalence of anaemia among term pregnant women in Peradeniya, Sri Lanka was observed and was associated with low socio economic status, low consumption of tea and poor nutrition lacking in red meat.
