    摘要:

    基于中国营养和健康调查(CHNS)和2019年实地调研数据,采用直接估计法,从膳食多样性、总热量、蛋白质与脂肪供热比四个指标检验农村居民收入与农业生产类型和营养的关系。研究表明:总收入对膳食多样性、热量、蛋白质供热比、脂肪供热比均呈正相关;随着农业收入占家庭总收入比重的增加,居民膳食多样性指数和营养指标均下降;种植业生产收入占家庭农业收入比重与膳食多样性指数、脂肪供热比成反比,与蛋白质供热比成正比;渔业生产收入比重与热量成正比;果蔬业生产收入比重与热量成反比,与蛋白质供热比成正比。促进农村居民总收入增长,拓展非农收入空间,并辅以营养知识普及和消费政策引导是今后一个时期内改善农村居民营养状况的着力点。

    Abstract:

    We used panel data of China Health and Nutrition Survey to examine the impacts of income and agricultural production categories on rural residents’ nutrition intake in terms of their dietary diversity,calorie intake,shares of calorie from protein and fat.Combined with field research data in 2019,this paper provided an in-depth analysis of the nutritional status of rural residents in China.The results showed that total income is positively related to dietary diversity,calorie,and shares of calorie from protein and fat.Worse nutrition has been found in the agricultural income dominant families compared to those non-agricultural income dominant.The proportion of crop income is negatively related to dietary diversity,share of calorie from fat,and positively related to share of calorie from protein.Caloric intake is positively related to Fishery income.Gardening income is negatively related to caloric intake while positively related to share of calorie from protein.Therefore,in addition to various nutrition knowledge and the guidance of consumption policies,it is also significant to increase rural residents’ overall income and expand their non-agricultural employment in an effort to improve their nutrition and health.
