目的：描述家庭视黄醇和类胡萝卜素的摄入量以及决定其摄入量的社会经济因素。主题：分析中使用了总共1001个家庭（农村地区771个，城市地区230个）的数据。被访者为家庭食品制造者。类胡萝卜素摄入量农村为4178（3154）μ g/人/天，城市为4208（3408）μ g/人/天，视黄醇摄入量农村为101（275）μ g/人/天，城市为201（470）μ g/人/天。多变量分析表明，与少于三个成员的家庭相比，四个或更多成员的家庭中的受试者消耗约700 μ g类胡萝卜素。家庭支出较高（第四个四分位数）的家庭比支出较低（第一个四分位数）的家庭多摄入约100 mg视黄醇/d。结论：植物性食物来源的类胡萝卜素是居民维生素A摄入的主要来源，家庭支出和家庭规模是其主要决定因素。食品强化和饮食多样化，特别强调促进动物性食品的消费，应该是克服越南维生素A缺乏症的关键战略。
Objective: To describe the household intakes of retinol and carotenoids and social economic factors determining their intakes.Subjects: Data on a total of 1001 households (771 in rural areas and 230 in urban areas) were used in the analyses. Interviewed person was household food preparer.Results: Mean (s.d.) intake of carotenoids was 4178 (3154) mu g/capita/day in rural and 4208 (3408) mu g/capita/day in urban areas and intake of retinol was 101 (275) mu g/capita/day in rural and 201 (470) mu g/capita/day in urban areas. Multivariate analyses show that the subjects in households with four or more members consume about 700 mu g carotenoids less compared to households with less than three members. Households with a higher expenditure (fourth quartile) consumed about 100 mg retinol/day more than those with a lower expenditure (first quartile).Conclusion: Carotenoids from plant food sources is the main source of vitamin A intake of the population and its main determinants are household expenditure and size of household. Food fortification and dietary diversification with special emphasis on promotion of consumption of animal foods should be key strategies for overcoming vitamin A deficiency in Vietnam.
