Abstract:ObjectiveTo analyze health behaviors and correlations with psychological resilience and family function in elderly patients with chronic obstructive pulmonary disease (COPD), and to designate relevant nursing responses. Methods Elderly patients with COPD admitted to the First Affiliated Hospital with Nanjing Medical University from January 2020 to June 2023 were selected as research objects. Health promoting lifestyle scale Ⅱ (HPLP Ⅱ), Connor-Davidson Resilience Scale (CD-RISC) and Family Adaptation Partnership Gowth and Resolve (APGAR) Index were used to evaluate the health behavior, psychological resilience and family function of elderly COPD patients. Pearson correlation coefficient was used to analyze the correlation of HPLP Ⅱ score with CD-RISC score and APGAR score in elderly COPD patients. Multiple linear regression analysis was used to analyze the influencing factors of health behavior in elderly patients with COPD. Results A total of 96 elderly patients with COPD were included in the study. HPLPⅡ score was (79.82±8.43), CD-RISC score was (52.74±6.38) and APGAR score was (6.13±1.46), all indicating a medium level. Pearson correlation analysis showed that HPLP Ⅱ scores were positively correlated with CD-RISC and APGAR scores in elderly COPD patients (P＜0.05). Multiple linear regression analysis showed that CD-RISC score（β′=0.201）, APGAR score（β′=0.219）, age (β′=0.233), marital status (β′=0.199), sleep quality (β′=0.184) and educational level (β′=0.212) were the influencing factors of health behavior in elderly patients with COPD (P＜0.05). Conclusion The health behavior of elderly patients with COPD is related to psychological resilience and family function. Targeted nursing intervention measures should be taken according to relevant influencing factors to improve the health behavior of patients.
