Association of Parkinson’s disease with accelerated bone loss, fractures and mortality in older men: the Osteoporotic Fractures in Men (MrOS) study

Summary Among community-dwelling older men, compared to those without Parkinson’s disease (PD), over approximately 5 years, those with baseline PD had a significantly greater rate of annualized total hip bone loss (−1.1% vs. 0.4%), proportion of incident non-spine fractures (14.9% vs. 7.2%) and mortality (34.8% vs. 9.5%). Introduction The objective of this study was to examine the association of Parkinson’s disease (PD) with bone loss and fractures in older men. Methods This prospective cohort study analyzed data from 5,937 community dwelling men aged ≥65 years at six clinical centers of the Osteoporotic Fractures in Men (MrOS) Study. At baseline and visit two (mean interval 4.6 +/−0.4 SD years), community-diagnosed PD was ascertained by self-report and hip bone mineral density (BMD) was measured using dual energy x-ray absorptiometry (DXA). Incident fractures were self-reported. Fractures and deaths were centrally adjudicated. Results At baseline, 46 (0.8%) men had PD. Age-adjusted mean annualized total hip bone loss was greater in men with vs. those without PD (−1.08% vs. −0.36%, p
