Association between cardiovascular disease risk and sarcopenia in community-dwelling Japanese older adults.

Aim: Sarcopenia's high prevalence in older adults with cardiovascular disease (CVD) suggests that the risk of comorbidity in sarcopenia might also be increased during the at-risk phase of CVD. However, the relationship between CVD risk and sarcopenia has not been elucidated. Therefore, the purpose of this cross-sectional study was to investigate the association between CVD risk and sarcopenia in community-dwelling Japanese older adults.

Methods: The participants in this cross-sectional study included 14 923 community-dwelling Japanese older adults (mean age 73.2 ± 5.6 years). The present study estimated the CVD risk using the revised World Health Organization risk chart, and classified CVD risk into "low" (<10%) and "mid-high" (≥10%). Assessments of sarcopenia, muscle mass, muscle strength and gait speed were measured based on the clinical definitions.

Results: Among the participants, 654 people (4.4%) had sarcopenia, and 4857 (32.6%) had CVD mid-high risk. A multiple logistic model showed that the CVD mid-high risk was associated with sarcopenia (odds ratio [OR] 1.55, 95% confidence interval [CI] 1.28-1.89). In addition, CVD mid-high risk was associated with low muscle mass (OR 1.74, 95% CI 1.50-2.01), low muscle strength (OR 1.25, 95% CI 1.14-1.37) and slow gait speed (OR 1.17, 95% CI 1.07-1.27) in the adjusted model.

Conclusions: Among community-dwelling older adults, high or moderate CVD risk was associated with an increased risk of sarcopenia. Our findings could help identify older adults with a future high risk for sarcopenia. Geriatr Gerontol Int 2024; ••: ••-••.
