Objective To investigate nutritional status of serum vitamin A among children aged 0-3 years in Hainan Province and factors associated with it,so as to provide scientific evidence to address vitamin A deficiency problem.Methods Stratified random sampling method was used to recruit 461 children aged 0-3 years who underwent health checkups at township health centers in 5 cities and counties in Hainan Province as study subjects.High-performance liquid chromatography was used to assess serum vitamin A levels,while information of the children's demographic and feeding characteristics were collected.The serum vitamin A levels and vitamin A deficiency of children with different characteristics were analyzed and compared.Results There were 276 males and 185 females.The average serum vitamin A levels was(369.12±134.81)ng/mL,with a marginal deficiency rate of 24.73%and a deficiency rate of 9.33%.There was no difference in the serum vitamin A levels between different gender(P>0.05),while the differences between children of different age groups were statistically significant(P<0.05).The highest marginal deficiency rate(45.98%)and the deficiency rate(22.99%)were in the 0-<6 months age group,and the marginal deficiency rate and the deficiency rate decreased with months(r=-0.414,P<0.05).Urban children had higher serum vitamin A levels and lower marginal deficiency and deficiency rates than those of rural children(P<0.05).Children who had fruit and vitamin A supplements intake daily had higher serum vitamin A levels and lower marginal deficiency and deficiency rates than those whose intake frequency≤6 times/week(P<0.05).Stratified regression analysis showed that fruit intake interpreted 2.10%of the variation in vitamin A nutritional status after controlling for demographic variables.Conclusion Vitamin A deficiency among children aged 0-3 years in Hainan Province is a mild public health issue.Monitoring should be enhanced,and timely vitamin A supplements intake and balanced diet should be the main intervention strategies.
