Abstract
Objective: The aim of this study was to investigate the importance of nutritional deficiencies and infections in the development of anaemia in pregnant Nepali women.
Design: Case-control study.
Setting: Patan Hospital, Kathmandu, Nepal.
Subjects: A sub-sample (n=479) of all pregnant women (n=2856) coming for their first antenatal visit in a 12 month period, 1994–1995. Women who had already received any micronutrient supplementation (n=82), and those whose serum samples showed macroscopic haemolysis (n=7) were excluded. The remaining women (n=390) were included in the statistical analysis. They were divided into three groups; a non-anaemic control group, haematocrit (Hct)>33% (n=82), and two case-groups: moderately anaemic, Hct 25–33% (n=254), and severely anaemic, Hct<25% (n=54).
Results: We found high prevalences of nutritional deficiencies and intestinal infections, both among cases and controls. The prevalence of low s-ferritin was high, especially among the severely anaemic women (55.6%). In a multiple logistic regression model, the presence of low s-vitamin A, elevated s-C-reactive protein or hookworm infection was associated with a significantly increased risk of severe anaemia. The adjusted odds ratios (95% CI) were 8.38 (1.99, 35.30), 4.91 (1.22, 19.67) and 5.43 (1.20, 24.61), respectively.
Conclusions: In addition to the present routine iron and folate supplementation to pregnant Nepali women, vitamin A supplementation needs to be considered. Prevention and treatment of infections should, together with dietary advice, be emphasized more strongly in the antenatal care.
