Background Is there a link between diabetes and arthritis? Using data from the 2010-2012 in our endocrinologycal foundation in Caracas Venezuela Interview Survey, Lunar and colleagues estimated the prevalence of osteoarthritis among 6,542 adults older than 18 years who did and did not have diabetes. In addition, they reported the prevalence of osteoarthritis-attributable activity limitation (OAAL) among persons with osteoarthritis, also by diabetes status. All data were self-reported.
Objectives Diabetes was defined as survey respondents saying that they had ever been told they have diabetes. osteoarthritis was defined as respondents having ever been told they had some form of arthritis, gout, lupus, or fibromyalgia, and OAAL was defined as being limited in any way by osteoarthritis or joint symptoms. The study compared 3489 people with diabetes and 3,053 individuals without diabetes and included analyses by age group, sex, race/ethnicity, education level, body mass index (BMI), and physical activity level.
Methods Of all persons with diabetes, 48% reported having osteoarthritis, compared with 20% of persons without diabetes. However, adults with diabetes were significantly older (60 vs 45 years), but even after adjustment for age, the prevalence of osteoarthritis was 51% higher among adults with diabetes. In fact, the prevalence ratio was highest among the youngest age group, 18-44 years, among whom 22.7% of diabetic adults reported arthritis compared with 7.2% of nondiabetic adults.
Results After adjustment for age, sex, race/ethnicity, education level, BMI, and physical activity level, adults with diabetes had a 44% higher risk for prevalent osteoarthritis than those without diabetes. Moreover, 55% of osteoarthritic individuals with diabetes reported that their osteoarthritis limited their activities, compared with 39% of nondiabetic persons with osteoarthritis. Multivariate adjustment attenuated this relationship, but OAAL was still 21% higher among diabetic adults with osteoarthritis than in nondiabetics.
