Demographic, Dietary, and Lifestyle Determinants of Vitamin D Status in the US Population: National Health and Nutrition Examination Survey, 2005-2006

摘要: DEMOGRAPHIC, DIETARY, AND LIFESTYLE DETERMINANTS OF VITAMIN D STATUS IN THE U.S. POPULATION: NATIONAL HEALTH NUTRITION EXAMINATION SURVEY, 2005-2006 by SHALINI PATEL Background: Determinants of vitamin status are interest when studying the epidemiology disease in population groups because is now recognized to decrease risk diseases such as osteoporosis, cancer, and cardiovascular disease. Understanding modifiable determinants important for managing deficiency at individual level addressing this issue level. Objective: The objective study was evaluate associations between serum (deficiency insufficiency) distinct demographic, dietary, lifestyle characteristics adults United States using a large, nationally representative sample survey, National Health Nutrition Examination Survey (NHANES) 2005-2006. Methods: consisted 2340 aged 20-59 who had 25(OH)D measured completed various questionnaires concerning dietary intake other factors. Multivariate logistic regression used estimate odds ratio (OR) deficiency, insufficiency, sufficiency based on characteristics. Statistical significance set α < 0.05. Results: prevalence higher obese than underweight normal weight (50.9% ± 4.57 vs. 29.3% 3.57), reported no sunburns ≥ 3 (49.9% 3.82 18.0% 3.07), use sun protective measures regularly do not (48.4% 3.93 27.0% 3.75). increased decreased. Non-Hispanic black were significantly more likely be deficient (OR = 45.27, 95% CI 17.27118.64) insufficient 9.37, 3.43-25.61) non-Hispanic white adults. Significant positive found several characteristics, namely obesity 7.43, 4.33-12.77), physical inactivity 1.63, 1.03-2.58) poor 2.34, 1.44-3.81), non-supplement or supplement with low amount 1.75, 1.05-2.89), activities that exposure sunlight (from OR 2.97, 2.14-4.13 5.30, 3.17-8.85). Conclusion: results demonstrate obesity, inactivity, D, increases U.S Future studies needed investigate whether supplementation, exposure, D-fortified foods efficient correcting insufficiency among these groups.
