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 cognitive status, congestive heart failure, chronic obstructive pulmonary disease, cerebrovascular disease, and levels of creatinine, hemoglobin, and albumin.

^*PTH tertiles: 1st ≤17.70 ng/L; 2nd 17.80–28.00 ng/L; 3rd ≥28.10 ng/L.

SE = standard error; SPPB = short physical performance battery; PTH = parathyroid hormone.
