Physical impairment was measured using the Medical Outcomes Score-Physical Functioning (MOS-PF), which is equivalent to items from the physical functioning scale of the SF-36 health survey (none/minor=score of 75–100; moderate=score of 50–74; and severe=score of <50). Percentage missing: physical activity=1.05%; physical functioning=10.47%; smoking status=0.30%.
