The aim of the present study was to examine the prevalence of sarcopenia in Chinese suburb-dwelling patients with cardiovascular risk factors and compared sarcopenia and sarcopenia components between subjects with and without cardiovascular risk factors.
This study was conducted on 766 Chinese suburb-dwelling subjects (488 patients with cardiovascular risk factors) who were examined using bioelectrical impedance analysis. Prevalence of sarcopenia was using Asian Working Group for Sarcopenia (AWGS) criteria. Furthermore, multiple logistic regression analysis was used to examine the effects of cardiovascular risk factors on sarcopenia and sarcopenia components.
The total prevalence of sarcopenia was 11.3% in patients with cardiovascular risk factors; prevalence was 7.4% and 35.8% in patients with cardiovascular risk factors aged 60-74 and ≥75, respectively. After adjustments for confounders (age, gender, BMI, smoking, drinking and physical activity), cardiovascular risk factors was independently associated with sarcopenia (OR=2.75, 95% CI=1.50-5.05). Among the individual components of sarcopenia, low gait speed (OR=2.70, 95% CI=1.10-6.67), but not low grip strength (OR=1.02, 95% CI=0.99-1. 05) and low muscle mass (OR=1.01, 95% CI=0.98-1.03) was associated with cardiovascular risk factors after multivariable adjustments.
The AWGS criterion is useful for defining sarcopenia and our data suggest that the prevalence of sarcopenia in Chinese suburb-dwelling patients with cardiovascular risk factors is high. Moreover, we find that cardiovascular risk factors were independently associated with sarcopenia. These characteristics may contribute to low gait speed in suburb-dwelling populations with cardiovascular risk factors.
