Notes: Model 1 was adjusted for sociodemographic variables (age, site, education), smoking status, physical activity, body mass index, total energy intake, and season. Model 2 was adjusted for variables in Model 1 plus cognition, congestive heart failure, chronic obstructive pulmonary disease, cerebrovascular disease, and levels of creatinine, hemoglobin, and albumin.
SE = standard error; SPPB = short physical performance battery.
