Quartile range (footnoted) and medians for PA min/d same as in Table 2. Model 1: mean±SE adjusted for accelerometer wear‐time, age, race‐ethnicity, education, smoking, alcohol, age at menopause, and SPPB score. Model 2: mean±SE adjusted for above plus BMI (except for BMI and waist models). BMI indicates body mass index; CRP, C‐reactive protein; MVPA, moderate‐to‐vigorous physical activity; PA, physical activity; SPPB, short physical performance battery.
