Inclusion criteria

Inclusion criteria: Elderly female patients with proximal femoral fractures who were discharged from a convalescent rehabilitation hospital and for whom data on post-discharge nutritional intake and readmission are available.

Exclusion criteria

Exclusion criteria: Participants meeting any of the following criteria will be excluded: (1) Missing data on post-discharge nutritional intake (2) Inability to confirm readmission status (3) Death during the follow-up period (4) Presence of severe comorbidities (e.g., malignant tumors, severe heart failure, or severe renal failure) that may substantially affect nutritional intake or the risk of readmission

Design outcomes

Primary

Measure	Time frame
Incidence of readmission within two years after discharge, defined as hospitalization due to fracture or fracture-related complications. Assessments will be conducted at 6, 12, and 18 months after discharge, and readmission status will be confirmed during the follow-up period up to 24 months.	—

Secondary

Measure	Time frame
Changes and between-group comparisons at 6, 12, 18, and 24 months after discharge in the following variables: (1) Nutrient intake (energy, protein, fat, carbohydrates, calcium, magnesium, zinc, vitamin D, vitamin K, vitamin C, and salt equivalent) (2) Body composition (muscle mass, skeletal muscle mass, body fat percentage, and skeletal muscle index) (3) Biochemical parameters (e.g., serum albumin) (4) Food group intake (grains, seafood, meat, vegetables, fruits, etc.)	—
