Dietary Vitamin A Intake of Chinese Middle Age and Elderly Adults in 9 Provinces from 1991 to 2009
摘要
Abstract
[Objective] To investigate dietary vitamin A intake status among Chinese middle age and elderly adults in 9 provinces in 2009 and the trends from 1991 to 2009. [Method] Aduhs aged 50-79 years old from China Health and Nutrition Survey (CHNS), from 1991 to 2009 were selected. Average intake of dietary retinol, carotene and total vitamin A were defined as key variables of vitamin A status. Vi- tamin A intake at different gender, age and area levels in 2009, and change trends from 1989 to 2009 by areas were analyzed. Trends of the ratio of retinol to total vitamin A and percents of vitamin A to RNI were also demonstrated. In 2009, average intake of dietary vitamin A, carotene and retinal were 602. 4 p~g RE/d, 1 570. 6 p.g/d and 373.8 p~g/d, respectively. Male had higher intake than females, while in- take in city and suburban were higher than those in town and village. Intake of vitamin A and carotene decreased slightly with floatation frem 1991 to 2009, while that of retinol increased since 1993. The ratio of retinol to vitamin A increased yearly, which in city, suburban, town and village increased from 62. 8% , 59. 4% , 60. 9% and 56. 9% in 1991 to 70. 9% , 73. 1% , 67. 0% and 68. 1% in 2009, respectively. However, adults in suburban and village had higher ratio of retinol to vitamin A than those in city and town. The percentage of population with dietary vita- min A intake above RNI briefly decreased from 30. 3% in 1991 to 28. 4% in 2009, while the percentage of population with dietary vitamin A in- take more than 40% RNI, 60% RNI, 80% RNI increased from 14. 6% , 12. 0% and 10. 0% in 1991 to 17. 7% , 13. 9% and I 1.4% in 2009. [Conclusion] Dietary vitamin A intake among Chinese middle age and elderly adults decreased slightly with floatation from 1991 to 2009, while that of retinol increased. However, it needs more attention to the lower vitamin A intake in town and village areas.关键词
