Abstract
Objective: To assess the vitamin A and iron status of lactating women.
Design: A population-based cross-sectional descriptive study.
Setting: A semi-arid rural area of Makhaza in Zimbabwe.
Subjects: Two hundred and seven lactating women with babies aged 2–12 months.
Methods: Serum retinol (SR) was measured by HPLC, serum ferritin (SF) by ELIZA, haemoglobin (Hb) by HemoCue and C-reactive protein (CRP) by a turbo metric method. A seven-day recall of consumption of vitamin A containing foods was recorded.
Main outcome measures: Relative dose response (RDR), SR, SF, Hb and CRP.
Results: Dark green leafy vegetables were the main sources of vitamin A; retinol-containing foods and yellow to red fruits and vegetables were rarely consumed. Five women had elevated CRP and these women had lower SR (P<0.001) than the rest. Forty percent of the women had vitamin A deficiency (SR<20 μg/dl), 76% had low liver stores of vitamin A (RDR>20%) while 15 women had both abnormal SR and abnormal RDR. Forty percent had anaemia (Hb<12 g/l) while 12% had iron deficiency (SF<12 μg/dl) and 4% (n=7) had iron deficiency anaemia.
Conclusion: Vitamin A and iron deficiencies are problems of public health significance among the lactating women in the Makhaza area.
Sponsorship: The study was sponsored by Sida through the Sida/Zimbabwe co-operation.
