Objective To explore the epidemiological status and related factors for comorbidities of osteoarthritis (OA) among adult residents in Beijing. Methods Based on the medical records of all designated medical institutes in Beijing from 2015 to 2017, relevant data of adult OA patients were collected, and the prevalence of major comorbidities such as type 2 diabetes, depression, hypertension and dyslipidemia in this population was statistically described and analyzed, and the differences among populations with different sociodemographic characteristics were compared. Results A total of 3 048 304 adult OA patients were included, with a mean age of 58.2±14.5 years, and females accounting for 62.2%. 79.8% of the subjects had at least 1 comorbidity, with the males (82.6%) having a higher prevalence than the females (78.1%). The prevalence of OA comorbidities was increased with age and statistically significant among different age groups (P < 0.05). The prevalence in the patients living in the rural areas (82.7%) was higher than that in urban areas (78.8%). The top 4 most common comorbidities were hypertension (68.0%), dyslipidemia (63.8%), type 2 diabetes (36.3%), and depression (8.2%). The males were more likely to suffer from hypertension, dyslipidemia and type 2 diabetes, while the females from depression. The proportion of OA patients with 1, 2, 3 or more kinds of comorbidities was 17.7%, 30.7%, 31.4% respectively. The risk factors for OA comorbidities included: male (OR=1.15, 95%CI: 1.14~1.16), ≥55 years old (OR=1.07, 95%CI: 1.07~1.07), living in rural areas (OR=1.66, 95%CI: 1.64~1.67), and taking manual labor (OR=1.02, 95%CI: 1.01~1.02). Conclusion The adult OA patients in Beijing have relatively high prevalences of comorbidities, including dyslipidemia, hypertension, type 2 diabetes and other diseases. More attention should be paid to the middle-aged and elderly patients and those in rural areas.
