D. Suharno et al., SUPPLEMENTATION WITH VITAMIN-A AND IRON FOR NUTRITIONAL ANEMIA IN PREGNANT-WOMEN IN WEST-JAVA, INDONESIA, Lancet, 342(8883), 1993, pp. 1325-1328
Nutritional anaemia, thought to be caused by iron deficiency, affects
50-70% of pregnant women in the developing world. The influence of vit
amin A and iron supplementation was studied in anaemic pregnant women
in West Java, in a randomised, double-masked, placebo-controlled field
trial. 251 women aged 17-35 years, parity 0-4, gestation 16-24 weeks,
and haemoglobin between 80 and 109 g/L were randomly allocated to fou
r groups: vitamin A (2.4 mg retinol) and placebo iron tablets; iron (6
0 mg elemental iron) and placebo vitamin A; vitamin A and iron; or bot
h placebos, all daily for 8 weeks. Maximum haemoglobin was achieved wi
th both vitamin A and iron supplementation (12.78 g/L, 95% CI 10.86 to
14.70), with one-third of the response attributable to vitamin A (3.6
8 g/L, 2.03 to 5.33) and two-thirds to iron (7.71 g/L, 5.97 to 9.45).
After supplementation, the proportion of women who became non-anaemic
was 35% in the vitamin-A-supplemented group, 68% in the iron-supplemen
ted group, 97% in the group supplemented with both, and 16% in the pla
cebo group. Improvement in vitamin A status may contribute to the cont
rol of anaemic pregnant women.
