Abstract: Objective To investigate the prevalence and associated factors of comorbidity among hypertension, diabetes, and dyslipidemia in adults in Fukang City, and to analyze the relationship with health-related behaviors, so as to provide an evidence base for the development and optimization of integrated management policies for these conditions. Methods A cross-sectional study was conducted utilizing data from the 2023 Adult Chronic Disease and Risk Factor Survey in Fukang City. Association rule mining was employed to analyze the influential factors of comorbidity among hypertension, diabetes, and dyslipidemia. Results The study included 2 941 adults. The standardized prevalence rates for hypertension, diabetes, and dyslipidemia were 13.86%, 7.24%, and 26.78%, respectively, with males exhibiting significantly higher rates than females (all P<0.01). The standardized prevalence of comorbidity involving these three conditions was 9.14%. Specifically, the standardized rates for comorbidities were 3.98% for hypertension with dyslipidemia, 1.68% for diabetes with dyslipidemia, 1.18% for diabetes with hypertension, and 0.77% for the coexistence of all three conditions. With a minimum support threshold of 3% and a confidence threshold of 10%, association rule analysis revealed the following high-lift rules: for males, a strong association existed with {excessive red meat consumption, sedentary behavior} (Confidence = 20.34%);for females, the strongest association was with {inadequate or excessive sleep duration} (Confidence = 11.36%). Among different age cohorts, the 45 to <60 age group was associated with {current smoking} (Confidence = 23.04%), whereas the ≥60 age group was linked to {excessive red meat consumption, insufficient physical activity} (Confidence = 23.96%). Conclusion The comorbidity of hypertension, diabetes, and dyslipidemia is prevalent among adults in Fukang City. Excessive red meat consumption, sedentary behavior, and insufficient physical activity were identified as common risk factors. These factors warrant significant attention in the implementation of integrated management strategies for these cardiometabolic conditions.
