Background: Interests between pain and frailty have been increasing in aging or aged societies. This study aimed to identify the prevalence of pain and frailty and to find the influence of pain on frailty. Methods: Subjects were selected with aged 65 yr or older among pooled Korea Health Panel data from 2009 to 2013. The prevalence of pain was determined by combining some pain and extreme pain and also, frailty was defined when subjects had at least one of the following 6-domain frailty: physical inactivity, mobility reduction, dependence of daily life, depression, multimorbidity, and disability. Results: The prevalence of pain and frailty was 56.1% and 59.8%. It was significantly higher in female (66.1% and 65.2%) and the oldest-old (69.4% and 71.8%). After adjusting for gender, age group, spouse, illiteracy, and economic activity, odds ratios of frailty for some pain and extreme pain were 2.8 (95% CI 2.6-3.0) and 10.5 (95% CI 8.0-13.8) in total subjects. The odds ratios of each 6-domain frailty for some and extreme pain were also significant. Among them, mobility reduction was 5.1 (95% CI 4.5-5.8) and 16.5 (95% CI 13.6-20.1), and dependence of daily life was 3.9 (95% CI 3.5-4.5) and 12.4 (95% CI 10.2-15.1). Conclusion: Among the elderly, prevalence of frailty (59.8%) was somewhat higher than that of pain (56.1%). Female and oldest-old had higher prevalence of pain and frailty. In addition, some pain and extreme pain had a decisive influence on frailty and each 6-domain frailty. Therefore, pain control is essential to prevent or manage frailty.
