The prevalence of comorbidities and the metabolic control status in patients with diabetes mellitus in Guangdong Province of China: a cross‐sectional study

Background Diabetes mellitus (DM) is a highly prevalent chronic disease worldwide and is frequently accompanied by comorbidities such as hypertension and dyslipidemia, which substantially impair patients’ quality of life and clinical prognosis. This study aimed to determine the prevalence of comorbidities (hypertension, dyslipidemia), evaluate metabolic control status (blood glucose, blood pressure [BP], lipids), and identify predictors of poor metabolic attainment among patients with DM in Guangdong Province, China, thereby providing evidence to inform targeted management strategies. Methods A cross-sectional study conducted from 2018 to 2020 enrolled 1575 patients with DM from the China National Diabetic Chronic Complications Study Cohort, recruiting participants across four geographically distinct regions of Guangdong Province. Data were collected through questionnaires, physical examinations, and laboratory assessments. The metabolic targets were defined as glycosylated hemoglobin (HbA1c)
