[Association between healthy lifestyle and risk of rehospitalization in male or female patients with chronic heart failure].

ABSTRACT

Objective: To explore the association between healthy lifestyle and risk of rehospitalization in male or female patients with chronic heart failure (CHF). Methods: Discharged patients with CHF of Henan Provincial People's Hospital Collaboration Hospital were recruited in our study from January 1,2017 to December 31, 2018. The basic information of patients were collected through the electronic medical record system,the questionnaires were used to collect the related influencing factors. Healthy lifestyle includes 4 items, namely non-smoking, moderate exercise, healthy body mass index (BMI) and reasonable diet.Multivariate logistic regression was used to analyze the association between healthy lifestyle and the risk of rehospitalization of CHF patients of different genders. Results: A total of 2 697 patients with CHF were enrolled in this study, including 1 308 male patients(621 rehospitalizations,687 controls)and 1 389 female patients(684 rehospitalizations,705 controls).Among male patients, there was no significant difference in age, residence, marital status, education level, average monthly income, and medical insurance between the rehospitalization group and the control group (all P>0.05). Among female patients, there was no significant difference in age, residence, marital status, education level, average monthly income, and medical insurance between the rehospitalization group and the control group (all P>0.05). Whether in male or female patients with CHF, we found that patients with 4 healthy lifestyles were associated with reduced risk of rehospitalization male patients OR=0.34, 95%CI 0.11-0.99, P=0.002,female patients OR=0.27, 95%CI 0.13-0.79, P=0.012. A combination of non-smoking and any other 2 healthy lifestyles was associated with reduced risk of rehospitalization male patients with no smoking, moderate exercise, healthy BMI, OR=0.32, 95%CI 0.11-0.99, P=0.043; female patients OR=0.28, 95%CI 0.12-0.93, P=0.032;male patients with no smoking, moderate exercise, reasonable diet OR=0.42, 95%CI 0.24-0.98, P=0.044,female patients OR=0.40, 95%CI 0.12-0.94, P=0.031;male patients with no smoking, healthy BMI, reasonable diet OR=0.31, 95%CI 0.21-0.92, P=0.039,female patients OR=0.27,95%CI 0.11-0.87, P=0.014. In female patients with CHF, the combination of non-smoking and moderate sports was associated with reduced risk of hospitalization (OR=0.23, 95%CI 0.19-0.97, P=0.038), while no similar results were seen in male patients (OR=0.65, 95%CI 0.33-1.84, P=0.315). Conclusion: Healthy lifestyle is associated with reduced risk of rehospitalization in patients with CHF, and the related healthy lifestyle and its combination may differ between male and female patients.
