Odds ratios with 95% confidence intervals are presented

Models are weighted and adjusted for age, race, number of years of school, smoking status, comorbidities, physical activity status. Overall model also adjusts for sex; There were n=3831 with non-positive weights or weights=0 that dropped out of the model

ADL – activities of daily living; BMI: Body mass index; GS: Grip Strength; IADL – instrumental activities of daily living; PL – physical limitations GS cutoffs men<26kg; women <16kg; GS/BMI men <1.0; women <0.56
