There is little evidence to support the general assumption that dietary carotenoids can improve vitamin A status. We investigated in Bogor District, West Java, Indonesia, the effect of an additional daily portion of dark-green leafy vegetables on vitamin A and iron status in women with low haemoglobin concentrations (< 130 g/L) who were breastfeeding a(More)
Nutritional anaemia, thought to be caused by iron deficiency, affects 50-70% of pregnant women in the developing world. The influence of vitamin 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(More)
Although vitamin A deficiency in children seems to increase susceptibility to infection and community trials have shown that vitamin A supplementation can reduce childhood mortality from infectious diseases, the underlying biological mechanisms are largely unknown. We conducted a randomised, double-masked, placebo-controlled clinical trial among children in(More)
Administration of 100,000 IU vitamin A at the time of measles immunisation is currently recommended for infants in developing countries. However, the safety and value of giving vitamin A, a potent immune enhancer, with live measles virus vaccines are unknown. We conducted a randomised, double-blind, placebo-controlled clinical trial in Indonesia to evaluate(More)
Iodine deficiency is a major cause of impaired mental development, goitre, and cretinism in many parts of the world. Because existing immunization programmes can be used to deliver oral iodized oil (OIO) to infants at risk, it was important to know whether OIO could adversely affect the antibody response to vaccines, such as trivalent oral poliovirus(More)
In a controlled trial 69 children with corneal xerophthalmia were given 200 000 IU oil-miscible vitamin A by mouth and a matched group of 45 children were given 100 000 IU water-miscible vitamin A intramuscularly. Both groups received an additional oral dose the next day. There was no detectable difference in the clinical response to the two regimes, even(More)
