  1. Sleep duration groups for older adult ≥65 years were defined as follow: Short-sleep group < 7 h, Normal-sleep group 7–8 h, Long-sleep group > 9 h
  2. aAdjusted model: Overweight analysis controlled for age, sex, race, marital status, and education level, while obese analysis adjusted for age, sex, race, marital status, education level, total number of family members, and number of children aged ≤5 years
