Abstract
Objectives
To investigate the prevalence and incidence rates of sarcopenia in Japanese community-dwelling people according to the criteria of the Asian Working Group for Sarcopenia 2019 recommendations, using a large-scale population-based cohort over a 10-year follow-up period.
Design
Prospective cohort study.
Setting and Participants
This study was conducted using data from the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study. In total, 1551 participants (521 men and 1030 women; mean age, 65.8 years) from the second ROAD survey (2008–2-10) were included in this study.
Methods
The participants from the second survey were followed-up at 4, 7, and 10 years. Skeletal muscle mass, handgrip strength, and walking speed were assessed. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 criteria. The incidence of sarcopenia was calculated using the person-year method. Cox proportional hazard model was used to assess risk factors for incident sarcopenia.
Results
The prevalence of sarcopenia was 8.1% (8.8% in men and 7.7% in women), and the prevalence of severe sarcopenia was 2.9% (2.7% in men and 3.1% in women). The incidence rates of sarcopenia were 17.8 per 1000 and 14.5 per 1000 person-years in men and women, respectively. Additionally, the incidence rates of severe sarcopenia were 6.4 per 1000 and 4.2 per 1000 person-years in men and women, respectively. The significant risk factors for the incidence of sarcopenia were age [+1 year; hazard ratio (HR), 1.10; 95% CI, 1.08-1.12] and body mass index (−1 kg/m2; HR, 1.27; 95% CI, 1.20-1.35). The significant risk factors for the incidence of severe sarcopenia were age (+1 year; HR, 1.18; 95% CI, 1.14-1.22) and body mass index (−1 kg/m2; HR, 1.21; 95% CI, 1.10-1.33).
Conclusions and Implications
The prevalence and incidence rates of sarcopenia in Japan were clarified in this study.
