Investigators from the University of Texas Medical Branch conducted an analysis of the 2012 Wave of the Mexican Health and Aging Study to determine the association of obesity with serum 25-hydroxyvitamin D in 1,772 older Mexican adults aged 50 years and older. They found that obese or overweight older Mexican adults had lower serum 25(OH)D concentrations than normal weight adults.
Mexico is currently undergoing an epidemiologic disease (communicable to non-communicable) and demographic transition (young to aging adults) with increasing obesity rates. Similarly, vitamin D has garnered significant attention in the scientific and public health community, with an estimated one billion individuals were reported as currently being either insufficient or deficient worldwide. However, vitamin D estimates among older Mexican adults and the role of obesity in vitamin D is unknown. In a sample of 1,772 older Mexican adults, representative of older adults residing in Mexico, older adults who were either overweight or obese were found to have significantly low serum 25(OH)D concentrations. This is the first study to investigation this relationship in Older Mexican adults. The study findings provide evidence for public health professionals and policy makers to address the obesity and vitamin D deficiency/insufficiency epidemics in Mexico, by regular screening of vitamin D concentrations in older adults, specifically targeting those who are obese or overweight.
The study was conducted using the 2012 Wave of the Mexican Health and Aging Study (funded by National Institute on Aging), and led by Dr. S Phani Veeranki, an Assistant Professor in the Department of Preventive Medicine and Community Health at UTMB. Other co-authors include Ms. Jacqueline Avila (a graduate student), Dr. Victoria Rontoyanni (postdoctoral fellow), Ms. Sapna Kaul and Ms. Rebeca Wong.
