To quantify and describe the distribution and trends of burden of nutritional deficiencies among children under 5 years old in China from 1990 to 2015.
Subnational data of China on children under 5 years old in 33 provinces and autonomous regions, which including 31 mainland regions, Hong Kong and Macao Special Administrative Regions, were extracted from the result of Global Burden of Disease Study 2015(GBD 2015). Based on the method of descriptive epidemiology, we analyzed the prevalence, mortality as well as disability adjusted life year(DALY) rate of nutritional deficiencies among children under 5 years old by sex, time and locations in China, as well as its temporal trend since 1990.
In 2015, the prevalence of nutritional deficiencies among children under 5 years old was 17. 26%, and the DALY rate was 776. 26 person-years per 100000. Compared to 1990, the DALY rate of nutritional deficiencies declined by 71. 42%. The DALY rate of nutritional deficiencies decreased in the past 25 years in Eastern, Central and Western China. Meanwhile, the gap in disease burden between boys and girls declined. Among diseases caused by nutritional deficiencies, burden of protein-energy malnutrition and iron deficiency anemia among children under 5 years old were relatively higher. Compared to 1990, the DALY rate of iron deficiency anemia among children under 5 years old declined by 15. 68%, which was lower than other nutritional deficiencies among children in 2015.
From 1990 to 2015, the disease burden caused by nutritional deficiencies among Chinese children under 5 years old showed downtrend. There were still differences of disease burden distributions between regions and common nutritional deficiencies.
量化并描述1990年至2015年中国5岁以下儿童营养缺乏负担的分布及趋势。
从《2015年全球疾病负担研究》（GBD 2015）结果中提取中国33个省和自治区（包括31个大陆地区、香港和澳门特别行政区）5岁以下儿童的省级以下数据。基于描述性流行病学方法，我们按性别、时间和地点分析了中国5岁以下儿童营养缺乏的患病率、死亡率以及伤残调整生命年（DALY）率，及其自1990年以来的时间趋势。
2015年，5岁以下儿童营养缺乏患病率为17.26%，DALY率为每10万人776.26人年。与1990年相比，营养缺乏的DALY率下降了71.42%。在过去25年中，中国东部、中部和西部营养缺乏的DALY率均有所下降。同时，男孩和女孩之间的疾病负担差距也在缩小。在营养缺乏引起的疾病中，5岁以下儿童蛋白质能量营养不良和缺铁性贫血的负担相对较高。与1990年相比，5岁以下儿童缺铁性贫血的DALY率下降了15.68%，在2015年低于其他儿童营养缺乏症。
1990年至2015年，中国5岁以下儿童营养缺乏所致疾病负担呈下降趋势。地区间疾病负担分布以及常见营养缺乏症仍存在差异。
