This paper examines the ability of three indicators to detect changes in women's vitamin A status.
Serum retinol concentration, milk vitamin A concentration, and milk vitamin A per gram milk fat were used to assess the vitamin A status of mildly deficient Indonesian women before and after supplementation in a randomized intervention trial.
Choice of indicator made a fourfold difference in the sample size required to measure a statistically significant change in vitamin A status.
Milk vitamin A per gram milk fat was the best indicator of response, milk vitamin A concentration was intermediate, and serum retinol concentration performed most poorly.
Serum retinol concentration was equally responsive across the range of vitamin A status in this population.
