ABSTRACT: OBJECTIVE: To identify correlates of anaemia during the first trimester of pregnancy among 366 urban South Indian pregnant women. DESIGN: Cross-sectional study evaluating demographic, socio-economic, anthropometric and dietary intake data on haematological outcomes. SETTING: A government maternity health-care centre catering predominantly to the needs of pregnant women from the lower socio-economic strata of urban Bangalore. SUBJECTS: Pregnant women (n 366) aged ≥18 and ≤40 years, who registered for antenatal screening at ≤14 weeks of gestation. RESULTS: Mean age was 22·6 (sd 3·4) years, mean BMI was 20·4 (sd 3·3) kg/m2 and 236 (64·5 %) of the pregnant women were primiparous. The prevalence of anaemia (Hb <11·0 g/dl) was 30·3 % and of microcytic anaemia (anaemia with mean corpuscular volume <80 fl) 20·2 %. Mean dietary intakes of energy, Ca, Fe and folate were well below the Indian RDA. In multivariable log-binomial regression analysis, anaemia was independently associated with high dietary intakes of Ca (relative risk; 95 % CI: 1·79; 1·16, 2·76) and P (1·96; 1·31, 2·96) and high intake of meat, fish and poultry (1·94; 1·29, 2·91). CONCLUSIONS: Low dietary intake of multiple micronutrients, but higher intakes of nutrients that inhibit Fe absorption such as Ca and P, may help explain high rates of maternal anaemia in India.
