Prospective relationship between baseline (2003–2005) RI and the risk of developing obesity at follow-up (2007–2009) among participants who were not obese at baseline in the MrOS Study.

Abbreviations: CI = confidence interval; MrOS = The Osteoporotic Fractures in Men Study; OR = odds ratio; RI = rhythm index. Model I: adjusted for baseline age and site.

Model II: additionally adjusted for race, education, smoking status, and alcohol use at baseline.

N and % were calculated based on participants in each quartile of the RI and OR and 95% CI were calculated as per 0.1 increase in RI.
