title: LOWER SERUM 25-HYDROXYVITAMIN D IS ASSOCIATED WITH OBESITY BUT NOT COMMON CHRONIC CONDITIONS: AN OBSERVATIONAL STUDY OF AFRICAN AMERICAN AND CAUCASIAN MALE VETERANS.
abstract: OBJECTIVE
  The study examined whether vitamin D insufficiency is a predictor of prevalent and/or incident common chronic conditions in African American men (AAM) and Caucasian American men (CAM).
  
  
  METHODS
  A total of 1,017 men were recruited at an urban VA medical center and followed prospectively for a mean of 5.4 years. Prevalent and incident chronic conditions evaluated were: obesity, type 2 diabetes, cancer, depression, dementia, and cardiovascular disease (CVD, including coronary artery disease [CAD], cerebrovascular accident [CVA], and congestive heart failure [CHF]). Univariate and multivariate regressions were performed to examine the association between 25-hydroxyvitamin D (25[OH]D) and these chronic illnesses.
  
  
  RESULTS
  This analysis was limited to 955 men (65.5% AAM, 27.2% CAM, 6.4% Hispanic) who had at least 1 year of follow-up (range, 1.0 to 7.1 years). Univariate analysis of the entire group showed that 25(OH)D correlated negatively with body mass index (BMI). There was no correlation between 25(OH)D and prevalent CVD (including separate analyses for CAD, CVA, and CHF), cancer, depression, dementia, all-cause mortality, or incident cancer, CAD, or CVA. Independent predictors of prevalent common conditions included increasing age, BMI, smoking, alcohol and polysubstance use, but not 25(OH)D levels.
  
  
  CONCLUSIONS
  The study does not support previously suggested associations of low vitamin D levels with prevalent common chronic conditions or increased risk for cancer, CAD, and CVA in a population of men with high burden of chronic disease. The finding that smoking and alcohol and polysubstance use are predictors of chronic conditions is an important reminder for addressing these risks during patient encounters.
  
  
  BACKGROUND
  AAM = African American men BMI = body mass index CAD = coronary artery disease CAM = Caucasian American men CHF = congestive heart failure CI = confidence interval CVA = cerebrovascular accident CVD = cardiovascular disease HTN = hypertension OR = odds ratio T2DM = type 2 diabetes mellitus VAMC = Veteran Administration Medical Center 25(OH)D = 25-hydroxyvitamin D.
