Objective: To compare the change of dietary vitamin A intake between 2002 and 2007 in Jiangsu Province.
Methods: The data from the Nutrition Survey in Jiangsu province in 2002 and the fellow-up survey in 2007 were statistically analyzed with SAS 8.0.
Results: The average intake of retinol equivalent was 766.9 microg/d per reference man in 2007 (776.0 microg for man, 738.8 microg for women, 738.8 microg for urban and 776.0 microg for rural residents), which was higher than that in 2002. The percentage of retinol equivalent intake equal to or higher than RNI was 39.0% in 2007 and 16.1% in 2002. The dietary intake of vitamin A in northern Jiangsu was lower than that in southern Jiangsu and was positively correlated with the income. The dietary retinol equivalent from vegetable and fruits was increased, and from animal foods was decreased in 2007.
Conclusion: The dietary vitamin A intake of residents in Jiangsu was improved in the past 5 years. The dietary vitamin A intake of low income population, women and residents in northern Jiangsu should be improved.
