Serum vitamin A concentrations and growth in children and adolescents in Gansu Province, China.
The association between serum vitamin A concentration and growth was assessed in a random sample of 650 children aged 0-14 years and 143 adolescents aged 15-19 years from the four prefectures of Jiayuguan, Linxia, Lanzhou and Tianshui in Gansu Province, China. Serum vitamin A concentrations were measured using a high performance liquid chromatograph. Height and weight were measured with standard methods. The results show that serum vitamin A concentration appeared to be the lowest in the age group 5-9 years which was only 0.28 mg/mL (95% confidence interval [CI]: 0.27-0.30) in males and 0.30 mg/mL (95% CI: 0.28-0.32) in females; and then it gradually increased with age. There was no statistically significant difference between males and females in any of the age groups. There were statistically significant correlations between vitamin A and weight (r = 0.37; P <0.001) and body mass index (r = 0.26; P < 0.001). This study suggests that serum vitamin A concentrations in children and adolescents may affect child growth. Concerted efforts to improve vitamin A status from a very early age become increasingly important if vitamin A has a genuine impact on child growth.
