RESUMEN
Objective@#To investigate the prevalence and influencing factors of comorbidity of chronic diseases among hypertensive patients with uncontrolled blood pressure in Huzhou City, so as to provide insights into community hypertension control. @*Methods@#Hypertensive patients with uncontrolled blood pressure at ages of 35 to 74 years were sampled using a cluster random sampling method from 5 districts (counties) of Huzhou City. Participants' demographics, living behaviors, and development of chronic diseases were collected using questionnaires, and the height, body weight, waist circumference and blood pressure were measured. Blood glucose, blood lipid and other biochemical parameters were detected, and the number and combination of comorbidity of chronic diseases were descriptively analyzed. Factors affecting the comorbidity of chronic diseases were identified using a multivariable ordinal logistic regression model.@*Results@# A total of 1 215 respondents were included, with a mean age of (60.83±7.76) years, and including 652 men (53.66%) and 563 women (46.34%). The prevalence of dyslipidemia, diabetes, hyperuricemia and cardiac encephalopathy was 45.10%, 30.95%, 23.05% and 5.10%, respectively. The prevalence of comorbidity of chronic diseases was 69.22% among respondents, and there were 497 respondents with one comorbidity (40.91%), 272 with two comorbidities (22.39%) and 72 with three and more comorbidities (5.93%). Hypertension+dyslipidemia (20.74%), hypertension+diabetes+dyslipidemia (9.96%) and hypertension+diabetes+dyslipidemia+hyperuricemia (4.36%) were predominant comorbid combinations. Multivariable ordinal logistic regression analysis showed that participants with overweight (OR=1.782, 95%CI: 1.390-2.286), obesity (OR=2.411, 95%CI: 1.802-3.222), grade 2 hypertension (OR=1.438, 95%CI: 1.077-1.919) had a higher risk of multiple comorbidities than those with normal body mass index and controlled blood pressure, and women (OR=0.563, 95%CI: 0.456-0.696) had a lower risk of multiple comorbidities than men. @*Conclusions@#The prevalence of comorbidity of chronic diseases was 69.22% among community hypertensive patients with uncontrolled blood pressure in Huzhou City, and the comorbidity of chronic diseases mainly included dyslipidemia and diabetes. Men, overweight, obesity and hypertension resulted in a high risk of comorbidity of chronic diseases.
