Abstract:
This study estimated the number of Korean adults aged 50 years or more with osteoarthritis (OA) based on the data from fifth Korea National Health and Nutrition Examination Survey (K-NHANES). We analyzed the knee X-ray finding and symptom questionnaire data obtained from the fifth K-NHANES conducted in 2010. The number of Korean adults aged 50 years or more with radiographic OA (those who had grade II or higher Kellgren-Lawrence score for OA) and symptomatic OA (those who had grade II or higher Kellgren-Lawrence score for OA and knee pain) were estimated using surveyfreq procedure of the SAS statistical package. It was estimated that there were 5,294,073 (proportion, 37.8%; 95% confidence interval, 4,739,995 to 5,848,150) patients with radiographic OA and 2,003,471 (proportion, 14.3%; 95% confidence interval, 1,693,239 to 2,313,703) patients with symptomatic OA among 14,010,367 Korean adults aged 50 years or more in 2010. This study has a limitation that symptomatic OA based on only the self report of symptom questionnaire. So, it is important that the physician do a physical examination to diagnose OA. Also, further efforts to investigate large-scale prospective studies are needed.
