Muscle Strength Assessed by Handgrip Strength Moderates the Relationship Between Overweight and Obesity With Cardiometabolic Risk Markers Among Adults and Older Adults.

Abstract

Background and aims: Few population-based studies have studied whether muscle strength (MS) levels influence the relationship between cardiometabolic markers with excess body weight. We investigate the possible moderator role of MS in the relationship between overweight and obesity with cardiometabolic markers. Methods: Cross-sectional analysis using data from two studies in Florianópolis, Brazil (EpiFloripa Adult Cohort Study, n = 862, 39.3 ± 11.4 years; EpiFloripa Aging Cohort Study, n = 1,197, 69.7 ± 7.1 years). MS was assessed by handgrip strength. Body mass index (BMI) was classified as overweight or obesity (BMI 25.0-29.9 or ≥30.0 kg/m2, respectively). Cardiometabolic markers included systolic (SBP) and diastolic blood pressure (DBP), C-reactive protein (CRP), lipids, glucose markers, and carotid intima-media thickness (CIMT). Linear regression models stratified by age groups (adults: <60 years; older adults: ≥60 years) and adjusted for confounders were used. Results: Compared to those with a normal BMI, overweight and obesity were related to higher SBP, DBP, lnCRP, ln triglycerides, fasting glucose (FG), and glicated hemoglobin (HbA1c), and inversely associated with HDL-C among adults and older adults (p value < .05 for all). Additionally, BMI was positively associated with LDL-C and CIMT only among adults (p value < .05). Among adults and older adults, elevated MS attenuated the adverse relationship between excess body weight with FG and HbA1c. Conclusion: Higher MS might help adults and older adults with overweight or obesity reduce their cardiovascular risk by keeping their FG and HbA1c at the same levels of those with a normal BMI.
