This study examined the effects of comorbid medical conditions (heart disease, pulmonary disease, hypertension and obesity) on the association of radiographic knee osteoarthritis (OA) with long-term difficulty in physical function. Data are from the National Health and Nutrition Examination Survey, 1971-1975 (NHANES I), a prospective epidemiologic cohort study, and the NHANES Epidemiologic Follow-up Study, 1982-1984 (NHEFS) and included 4059 persons who were 45-74 years old and participated in the detailed examination component of NHANES I. Knee OA was ascertained by anterior-posterior bilateral radiographs of the knee and self-report of knee pain, heart and pulmonary disease by self report of disease or symptoms, and hypertension and obesity by blood pressure and weight measurements. The presence of symptomatic knee OA at NHANES I was associated with reported difficulty at NHEFS 1982-84 in functions which used the lower extremity (ambulation and transfer). The presence of coexistent chronic conditions, particularly heart disease, pulmonary disease and obesity, increased the likelihood of subsequent disability. These findings suggest that knee OA is associated with long-term physical disability, and that the presence of coexistent chronic disease may increase the amount of long-term disability from knee OA.

The purpose of the study is to evaluate influences of the introduction of 30% co-payments on potential visit behavior using a questionnaire in order to determine whether "employment state of the spouse" and "number of dependent children", as indicators of economic backgrounds, affect visits to physicians in a health insurance society. The subjects were 1,674 insured consisting of 1,165 males and 509 females, who underwent a regular health examination in July 2002, in a health insurance society. In the survey, they were asked whether the subject "will reduce" or "will not reduce" visits to physicians due to the increase in co-payments in the health insurance system scheduled in 2003. Multivariate analyses showed that "employment state of the spouse" was significantly related to the reduction in visits for myocardial infarction or stroke, cancer or heart disease, and hypertension and diabetes mellitus. Concerning "number of dependent children", it was related to the risk of reducing visits to physicians for myocardial infarction or stroke, trauma or fracture, cancer or heart disease, and low back pain or knee pain. Finally, upper limit expenditures of co-payments of physicians to visits due to hypertension and diabetes mellitus were related to "number of dependent children". The study results suggest that "employment state of the spouse" and "number of dependent children" are significant factors to affect potential visits to physicians after the introduction of 30% co-payments.

Knee osteoarthritis is the most common chronic joint disorder in elderly people. However, a population-based, longitudinal study on health-related quality of life in knee osteoarthritis has not been conducted in Japan. We studied 333 women aged 50 years and older at baseline, with 8 to 9 years of follow-up. Anteroposterior weight-bearing knee radiographs were obtained at baseline and graded according to the Kellgren-Lawrence criteria. Definite osteoarthritis was defined as Kellgren-Lawrence grade 2 or higher in at least 1 joint. At baseline, all participants were asked if they had knee pain and comorbidities (heart disease, lung disease, stroke, or diabetes mellitus). Height (m), weight (kg), and chair stand time were measured. At follow-up, quality of life in knee osteoarthritis was evaluated using the Japanese Knee Osteoarthritis Measure score. Multiple linear regression analysis showed that age, knee osteoarthritis, knee pain, comorbidity, and increasing chair stand time were independently related to subsequent health-related quality of life. These findings suggest that treating knee osteoarthritis and comorbidities, managing pain, and optimizing lower extremity muscle strength may be effective targets for intervention.
