all coefficients expressed per SD increase in predictor variables: TEE=400 kcal, step count=3002 steps, PASE score=67, active time 59 min, non-sedentary time=112 min. The outcomes variables (Shannon Index, and Inverse Simpson Index) were not standardized. Multivariate models adjusted for age, race, BMI, clinical center, library size, and # of chronic conditions (fall history, hip fracture, myocardial infarction, stroke, congestive heart failure, diabetes, cancer, COPD, rheumatoid arthritis, osteoarthritis, depression, visual impairment, Parkinson’s disease, and Alzheimer’s disease).
