Data from: Classification of the trajectory of changes in food intake in special nursing home for oldest-old in the 6 months before death: a secondary analysis

This dataset is derived from a secondary analysis of a retrospective cohort study conducted in 2024. Participants included those who were aged 65 or older, had stayed in a special nursing home for more than six months before death, were able to take oral intake, and died in the nursing home. Exclusion criteria included deaths outside the nursing home and inability to take oral intake during the study period.The nursing homes were managed by three organizations across different regions in Japan. Data were collected from electronic care files maintained by the nursing homes. The food intake data, visually assessed by care providers, are recorded on a scale of 1 to 10 for each meal component. The average weekly food intake for the 24 weeks leading up to each resident’s death was calculated.
