Sex Differences in the Prevalence of Metabolic Syndrome Based on Leg Strength, Cardiorespiratory Fitness, and Skeletal Muscle Mass in Elderly

Background: Metabolic syndrome (MetS) is characterized by abdominal obesity, high blood glucose, and dyslipidemia. Low fitness, muscle mass, strength increase the risk of MetS. The characteristics these variables are highly interrelated. This cross-sectional study aimed to analyze prevalence MetS combining leg (LSTR), cardiorespiratory fitness (CRF), appendicular skeletal mass (ASM) in elderly men women. Methods: Participants included 1420 persons aged 65–79 years (men: 753, women: 667). An isokinetic dynamometer was used measure LSTR; CRF evaluated measuring maximum oxygen uptake; ASM assessed using bio-impedance analysis. measured CRF, LSTR, were converted relative values dividing body weight grouped into ‘high’ ‘low’ based on median value. diagnosis five criteria: waist circumference, pressure, high-density lipoprotein cholesterol, triglycerides, fasting glucose. diagnosed when participant fulfilled 3 or more criteria, odds ratios (ORs) analyzed logistic regression. Results: 32.1% 30.3% women, respectively. LSTR significantly higher non-MetS group compared those both sexes. OR for 3.6-fold low group, 3.5-fold 2.3-fold than groups. In increased 1.3-fold with 3.7-fold CRF. exhibited a 2.4-fold women combined group. Despite ASM, 3.9-fold Conclusions: relatively decreased Furthermore, despite addition, even if low, metabolic did not high. conclusion, two three increased.
