Higher Level of Obesity Is Associated with Intensive Personal Care Assistance in the Nursing Home.

The study looked at residents at one point in time, so it cannot show that obesity caused more assistance needs. BMI from height and weight may be less accurate in older adults with short stature. Residents younger than 65 were excluded, so findings may not apply to them. Activities that did not occur or were done by nonfacility staff were excluded, which may understate some assistance patterns. The data did not capture how long assistance took or whether more than two staff were needed, so the study cannot estimate extra nursing hours or exact staffing burden. Some mobility activities showed no association before adjustment; the association emerged after accounting for dementia and cognition, suggesting confounding is important.

The study reports NIH extramural research support. One author holds stock of unknown value in PointRight, an information services company for long-term and post-acute care, was a founder but divested much equity and left the board, and receives compensation in the $20,000-40,000-per-year range from HRC Manor Care and NaviHealth. The other authors declared no relevant conflicts.

Do not read the higher two-person assistance rates as proof that obesity causes greater staffing need. The study is cross-sectional, and it did not measure how much time staff spent or whether more than two people were needed.
