Abstract

Abstract

Objective To assess the nutritional status of vitamin A among adults of ethnic minority groups native to Yunnan Province, and provide scientific evidence for healthy eating promotions. Methods Between 2016 and 2020, 841 adults were randomly sampled from seven ethnic minority groups according to the sex and age composition in the 6^thnational census. The serum retinol level was determined using high-performance liquid chromatography （HLCP）, and judged by the WHO criteria. Vitamin A intake was calculated through a dietary survey and judged by reference to the dietary guidelines. Results The median serum vitamin A concentration was 0.55 mg/L （ranging from 0.44 to 0.68 mg/L） and significant differences were found in sex, race, education and income levels （all P < 0.05）. The prevalence of vitamin A deficiency and marginal deficiencies were 0.7% and 3.7%, respectively. The median of dietary vitamin A intake was 406.0 μg retinol equivalents （RE） and 67.0% of the subjects consumed less vitamin A than the Chinese Estimated Average Requirement （EAR）. The major food sources of vitamin A were dark vegetables, eggs, light vegetables and meat, accounting for 86.6% of total vitamin A intake. Conclusion The serum vitamin A concentration is relatively good in the population, whereas inadequate vitamin A intake remains a problem, especially for certain ethnic groups, older and poor adults.
