Abstract:
Objective To investigate the current situation of hypertension in community-dwelling patients with diabetes and to analyze its influencing factors, guide personalized health management for patients with diabetes. Methods A total of 2 591 health records of diabetes patients registered at the Fangzhuang Community Health Service Center in Fengtai District, Beijing, from January 2023 to January 2024, were included in a cross-sectional survey. Based on random forest model and LASSO regression, the influencing factors associated with hypertension in patients with diabetes were explored. Results The prevalence of comorbid hypertension in community-dwelling patients with diabetes was 87.42% (2 265 people). The results of random forest algorithm showed that the lowest error was observed when the lambda (λ) value was 0.003 9, corresponding to eight key influencing factors. The were TG/HDL-C, estimated glomerular filtration rate (eGFR), BMI, fasting blood glucose, age, duration of diabetes, systolic blood pressure, and education background. The results of the multivariate stepwise regression analysis indicated that eGFR (OR=0.980, 95% CI: 0.969-0.990), TG/HDL-C (OR=1.083, 95% CI: 1.022-1.147), BMI (24-28 group: OR=1.469, 95% CI: 1.140-1.893; >28 group: OR=2.340, 95% CI: 1.561-3.509), age (>75 years group: OR=1.844, 95% CI: 1.125-3.021), and systolic blood pressure (OR=1.053, 95% CI: 1.031-1.076) were influencing factors of comorbid hypertension in diabetic patients (P < 0.05). Conclusion The prevalence of hypertension was notably high among community-dwelling patients with diabetes. Elevated TG/HDL-C ratio, reduced eGFR, older age, and obesity were significantly associated with increased risk of hypertension. Effective management should include regular monitoring of TG/HDL-C levels, assessment of renal function, and personalized interventions focused on glycemic control, weight management, and health education tailored to the patient' s age and body mass index. This approach can help reduce the risk of hypertension in diabetic patients, decrease their long-term cardiovascular disease burden, and facilitate an upstream shift diabetes management.
