留守儿童是近些年在中国新出现的社会群体,其数量急剧增加。离开父母的照顾,留守儿童往往易于遭受由贫穷的生活环境和看护人低的教育水平所引起的营养不足。营养改善对促进农村留守儿童的健康与生长发育具有重要意义。本文就中国农村留守儿童营养改善的主要研究现状进行综述,为今后实施相关干预和卫生政策提供参考依据。 The number of left-behind children is a newly emerging social group in China in recent years, and their number has risen sharply. Leaving their parents’ care, left-behind children are often vulnerable to undernutrition caused by a poor living environment and a low educational level of caregivers. Nutritional improvement is of great importance for promoting the health and growth of left-behind children in rural areas. This review summarizes the current status of the research on the nutrition improvement of left-behind children in rural areas in China, and provides a reference for the implementation of relevant interventions and health policies in the future.
