      abstract = {Back pain is a prevalent and costly ailment for older  Americans, with significant personal and population  level  impact. Low serum 25-hydroxyvitamin D [25(OH) vitamin D]  levels are common and are  hypothesized to contribute to  musculoskeletal pain. Cross-sectional studies have  indicated an association  between vitamin D deficiency and  increased back pain but there is a paucity of robust  prospective cohort  studies representing this topic in the  literature, particularly in men.   This prospective cohort  study was performed in a random sample of 1608 U.S. men  from the  Osteoporotic Fractures in Men Study (MrOS) all of  whom were at least 65 years of age and community-  dwelling.},
