Plasma retinol and alpha-tocopherol level and growth indices of 7 months old healthy Thai infants in Bangkok.

A cross-sectional study was conducted to measure plasma retinol and alpha-tocopherol status and the growth indices of 66 healthy Thai infants aged about 7 months old. The mean (SD) plasma retinol and alpha-tocopherol level were 1.59(0.31) and 25.40(7.01) micromol/l respectively. For their weight, height, and body mass index, the mean (SD) values were 7.96(0.93) kg, 69.95(2.42) cm, and 16.25(1.43) respectively. There was a remarkable proportion of improper feeding. However there were no correlations between plasma retinol level, plasma alpha-tocopherol level, growth indices and duration of breast milk, formula milk, weaning food feeding except alpha-tocopherol level which positively correlated with duration of breastfeeding.
