To assess the intake of thiamine, riboflavin and niacin and estimate the association between the adequacy of intake of those three B-vitamins and risk factors among older Chinese adults.
A total of 3222 adults aged 65 and above with completed dietary data were derived from the 2015 survey of China Nutritional Transition Cohort Study 2015. The total subjects. Dietary data was recorded by three consecutive days with 24-hour recalls. The intake of those three B-vitamins were assessed by comparing with Chinese dietary thiamine, riboflavin and niacin reference intakes. The food sources of three vitamins were analyzed. Multivariate Logistic regression was used to estimate adjusted odds ratios for factors associated with the inadequacy of intake of those three vitamins.
The median daily intake of thiamine, riboflavin and niacin was 0. 8, 0. 7 and 12. 8 mg in males, and 0. 7, 0. 6 and 10. 9 mg in females, respectively. Adults aged 80 and above and living in the southern regions were more likely to have inadequate thiamine intake than adults aged 65-79 and living in northern regions, respectively. Adults had inadequate intake of riboflavin were more likely to be living in a village and adults with lower education levels than adults living in a city and adults with higher education levels. In males, adults had inadequate intake of niacin were more likely to be 80 years and above, with lower education levels, living in the northern regions, living in a village and with the lowest income. In females, adults had inadequate intake of niacin were more likely to be with lower education, living in northern regions and living in a village.
About 80% adults were at the risk of the inadequate intake of thiamine and riboflavin in China. Age, education, income, regions and areas of residence were associated with the intake of thiamine, riboflavin and niacin.
评估硫胺素、核黄素和烟酸的摄入量，并估计中国老年成年人这三种B族维生素摄入充足程度与风险因素之间的关联。
共有3222名65岁及以上且饮食数据完整的成年人来自2015年中国营养转型队列研究调查。通过连续三天的24小时膳食回顾记录饮食数据。通过与中国膳食硫胺素、核黄素和烟酸参考摄入量进行比较来评估这三种B族维生素的摄入量。分析了三种维生素的食物来源。采用多因素Logistic回归估计与这三种维生素摄入不足相关因素的调整比值比。
男性硫胺素、核黄素和烟酸的日均摄入量中位数分别为0.8、0.7和12.8毫克，女性分别为0.7、0.6和10.9毫克。80岁及以上的成年人以及居住在南方地区的成年人分别比65 - 79岁的成年人以及居住在北方地区的成年人更有可能硫胺素摄入不足。核黄素摄入不足的成年人比居住在城市且教育水平较高的成年人更有可能居住在农村且教育水平较低。在男性中，烟酸摄入不足的成年人更有可能年龄在80岁及以上、教育水平较低、居住在北方地区、居住在农村且收入最低。在女性中，烟酸摄入不足的成年人更有可能教育水平较低、居住在北方地区且居住在农村。
在中国，约80%的成年人存在硫胺素和核黄素摄入不足的风险。年龄、教育程度、收入、地区和居住区域与硫胺素、核黄素和烟酸的摄入量有关。
