VITAMIN D STATUS OF AMERICAN ADULTS AGE 18 YEARS AND OLDER

Americans are not reaching sufficient levels of serum 25-Hydroxy Vitamin D3 (25(OH)D3), and some groups are at a higher risk of developing vitamin D deficiency. Having a sufficient level of 25(OH)D3 can help prevent diseases like osteoporosis, certain types of cancers, cardiovascular disease, and hypertension. The data of 7479 American participants 18 years of age and older were derived from the NHANES 2001-2002 and NHANES 2003-2004 surveys. These participants were then analyzed to assess serum 25(OH)D3 levels. The variables used were age, gender, ethnicity, Body Mass Index (BMI), and smoking status. The statistical software, SUDDAN was used to control the weights of the samples, and least square means were calculated to control the confounding factors. This book provides the results for the variables mentioned above.
