Abstract: Objective To explore the status of functional physical fitness of elderly community patients with chronic diseases, and analyze its influencing factors. Methods A multi‐stage stratified sampling was used to randomly select communities in Chaoyang District, Beijing from September to December 2022, and at least 220 elderly patients with chronic diseases were recruited from the selected communities as research objects to carry out senior fitness test （SFT）, and questionnaire survey was adopted to collect their basic information, disease status, physical exercise, and other information. Descriptive analysis method was used to analyze the functional physical fitness of elderly patients with chronic diseases, and univariate and multivariate analysis methods were used to analyze the factors affecting the functional physical fitness. Results A total of 651 elderly patients with chronic diseases were recruited, of them 294 were poor in physical fitness, with an incidence rate of 45.16%. Multivariate logistic regression analysis showed that age （OR=4.035, 11.811）, overweight or obesity （BMI≥24.0 kg/m²） （OR=2.517）, limb pain （OR=2.032）, chronic respiratory disease combined with bone disease （OR=2.550）, and lack of physical exercise （OR=3.888） were independent risk factors for poor physical fitness in elderly patients with chronic diseases. Conclusions Elderly patients with chronic diseases have poor functional physical fitness, so physical exercise should be strengthened for the elderly, overweight or obesity, body pain, and other high‐risk groups, actively treat the underlying diseases, and give targeted intervention measures and guidance suggestions.
