This study aimed to learn the nutritional status of vitamin A and D among rural children and adolescents and to explore related dietary and exercise behaviors. A total of 10 counties (cities, districts) from 90 counties (cities, districts) in Zhejiang Province were selected by the method of random cluster sampling. Children and adolescents were investigated and their food and nutrient intake were calculated. The concentration of serum vitamin A in urban area was 0.38 ng\/ml, which was higher than that in rural area (<jats:italic>p<\/jats:italic> &amp;lt; 0.05); while the concentration of serum vitamin D in urban area was 21.25 mg\/L, which was lower than that in rural area (<jats:italic>p<\/jats:italic> &amp;lt; 0.05). The concentration of serum zinc was 101 \u03bcg\/dl in urban area and 107 \u03bcg\/dl in rural area (<jats:italic>p<\/jats:italic> &amp;lt; 0.05). The intake of dietary fiber, calcium, vitamin A, vitamin B1, vitamin B2, and vitamin C was lower than the recommended value. In rural area, the intakes of cereals, tubers and beans, livestock, poultry and meat of children and adolescents were higher than the recommended values; while the intake of vegetables, fruits, eggs, milk, fish and shrimp, soybean and nuts was lower than the recommended value. The intake of edible oil and salt is higher than the recommended value. The time of medium and high intensity exercise time in rural area is more than that in urban area in the age group of 12\u201317 years, while the sitting time is less than that in urban area. Children and adolescents living in rural area should be guided to eat reasonably, and to choose foods with high nutrient density and with low oil, salt and sugar.<\/jats:p>","DOI":"10.3389\/fnut.2022.1088155","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T05:23:22Z","timestamp":1673501002000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Assessment of serum Vit A, D and zinc nutritional status and related dietary and exercise behaviors of children and adolescents in rural and urban area"],"prefix":"10.3389","volume":"9","author":[{"given":"Yan","family":"Zou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-chun","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meng-jie","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danting","family":"Su","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong-hua","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"journal-title":"Malnutrition: it\u2019s about more than hunger.","year":"2017","key":"B1"},{"journal-title":"Micronutrient deficiencies-vitamin A deficiency","year":"2022","key":"B2"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.3390\/nu14153166","article-title":"Vitamin D-related risk factors for maternal morbidity during pregnancy: a systematic review.","volume":"14","author":"Su\u00e1rez-Varela","year":"2022","journal-title":"Nutrients."},{"journal-title":"Vitamin and mineral requirements in human nutrition.","year":"2005","key":"B4"},{"journal-title":"Global prevalence of vitamin a deficiency in populations at risk 1995\u20132005: WHO global database on vitamin A deficiency.","year":"2009","key":"B5"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2021.694106","article-title":"Vitamin A levels among pre-school children of central and Western China.","volume":"9","author":"Chen","year":"2021","journal-title":"Front Public Health."},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.3390\/nu8100610","article-title":"Vitamin D intake and serum 25-hydroxyvitamin D levels in korean adults: analysis of the 2009 Korea national health and nutrition examination survey (KNHANES IV-3) using a newly established vitamin d database.","volume":"8","author":"Yoo","year":"2016","journal-title":"Nutrients."},{"key":"B8","doi-asserted-by":"publisher","first-page":"273","DOI":"10.1016\/j.jped.2020.08.006","article-title":"Vitamin D deficiency in children and adolescents with obesity: a meta-analysis.","volume":"97","author":"Fiamenghi","year":"2021","journal-title":"J Pediatr."},{"key":"B9","doi-asserted-by":"publisher","first-page":"550","DOI":"10.1590\/1806-9282.63.06.550","article-title":"Association between physical activity and vitamin D: a narrative literature review.","volume":"63","author":"Fernandes","year":"2017","journal-title":"Rev Assoc Med Bras."},{"key":"B10","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1146\/annurev-nutr-122019-120635","article-title":"Dietary and physiological effects of zinc on the immune system.","volume":"41","author":"Wessels","year":"2021","journal-title":"Annu Rev Nutr."},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0050568","article-title":"Estimating the global prevalence of zinc deficiency: results based on zinc availability in national food supplies and the prevalence of stunting.","volume":"7","author":"Wessells","year":"2012","journal-title":"PLoS One."},{"journal-title":"Physical status: the use and interpretation of anthropometry; Report of a WHO expert committee.
