Description
Summary:Summary Context While the prevalence of vitamin D deficiency is well described in various populations, limited data are available regarding longitudinal variation in serum 25‐hydroxyvitamin D concentrations. Objectives To evaluate the temporal trends in serum 25(OH)D, prevalence of vitamin D deficiency and factors influencing these trends. Participants, Design and Setting: Adults enrolled in the Dallas Heart Study, a longitudinal, probability‐based, multiethnic, population study in Dallas, Texas, USA. Main Outcome Measures Prevalence of vitamin D deficiency and predictors of change in serum 25(OH)D. Results A total of 2045 participants had serum 25(OH)D measured on two occasions (2000‐2002 and 2007‐2009) at a median interval of 7 years. Serum 25(OH)D decreased (42.7‐39.4 nmol/L, P
