  1. All linear mixed models are adjusted for age, physical activity (Physical Activity Scale for the Elderly Score), smoking status, Charlson co-morbidity score, education, race, cohort type (incidence, progression, control). Referent category is the neither dynapenia nor obesity group. Time-dependent co-variates are included in time x group interaction. LLDI was only available at 4-year follow-up thereby no time interaction term model was considered for this outcome measure
  2. Dyn dynapenia, Obes Obesity, β beta-coefficient of regression model, SE standard errors, LLDI late-life functional and disability index, MCS mental component score, PCS physical component score, SF short form
