China is rapidly moving toward an aging society with a large population; however, evidence on the epidemiological trends in nutritional deficiency among the Chinese elderly is limited. Data on the incidence of nutritional deficiency among Chinese adults aged 65 years or above from 1990 to 2019 were extracted from the Global Burden of Disease 2019 database. We used the joinpoint regression method to estimate the average annual percentage change (AAPC) and to describe trend patterns. Age, period, and cohort effects were determined using age\u2013period\u2013cohort models. From 1990 to 2019, the incidence of vitamin A deficiency and iodine deficiency among Chinese older adults decreased from 1784.12 and 8.20 to 304.27 and 7.26 per 100,000, with AAPCs of \u22120.41 (\u22120.44, \u22120.38)% and \u22125.86 (\u22126.29, \u22125.43)%, respectively. A continually increasing trend was seen for incidence rates of protein-energy malnutrition, from 1342.02 to 2275.87 per 100,000 person-years, with an AAPC of 1.70 (1.40, 2.01)%. These trends were more pronounced among men than women. A strong age effect and birth cohort effect were present. Specifically, the population that was older or born later had a lower incidence of deficiencies in vitamin A and iodine but a higher incidence of protein-energy malnutrition. The results show a substantial reduction in vitamin A and iodine deficiencies among the Chinese elderly, and health policies and public awareness are needed to address the burden of protein-energy malnutrition in this population.<\/jats:p>","DOI":"10.3390\/nu14235008","type":"journal-article","created":{"date-parts":[[2022,11,25]],"date-time":"2022-11-25T03:00:13Z","timestamp":1669345213000},"page":"5008","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Temporal Trends in Incidence of Nutritional Deficiency among Older Adults in China: A Secondary Analysis of the Global Burden of Disease Study 1990\u20132019"],"prefix":"10.3390","volume":"14","author":[{"given":"Linqi","family":"Xiao","sequence":"first","affiliation":[{"name":"Hospital Management Institute of Wuhan University, Zhongnan Hospital of Wuhan University, Wuhan 430071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jialin","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine, School of Health Sciences, Wuhan University, Wuhan 430071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Likai","family":"Lin","sequence":"additional","affiliation":[{"name":"Hospital Management Institute of Wuhan University, Zhongnan Hospital of Wuhan University, Wuhan 430071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Han","sequence":"additional","affiliation":[{"name":"Hospital Management Institute of Wuhan University, Zhongnan Hospital of Wuhan University, Wuhan 430071, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,25]]},"reference":[{"key":"ref_1","unstructured":"National Bureau of Statistics of China (2022, September 01).
