The aim of the present study was to investigate the independent and joint associations among muscle strength (MS) and obesity with blood pressure, atherosclerosis, and laboratory markers. This was a cross-sectional study comprising a representative sample of 642 adults (men: 44.9%, 39.9 ± 11.2 years; women: 55.1%, 39.3 ± 11.1 years) from Florianópolis, Brazil. MS was assessed by handgrip strength. Obesity was defined as a Body Mass Index (BMI) ≥30.0 kg/m² and a waist circumference ≥80.0 cm in women and ≥90.0 cm in men. Clinical variables included systolic (SBP) and diastolic blood pressure (DBP), C-reactive protein (CRP), lipids, glucose metabolism markers and carotid intima-media thickness (IMT). Linear regression models stratified by sex and adjusted for confounders were used. Higher MS levels were related to lower CRP (up to 0.59 times lower), triglycerides (up to 0.33 times lower), HOMA-IR (up to 0.35 times lower), and higher HDL cholesterol (up to 5.2 mg/dL) levels among men. Among women, higher MS levels were related to lower SBP and DBP (up to -10.2 mmHg), CRP (up to 0.56 times lower), HOMA-IR (up to 0.27 times lower) and IMT (up to -4.8 × 10-2 mm). In addition, MS was inversely related to triglycerides and HOMA-IR among obese men, inversely related to CRP among obese men and women, and inversely associated to DBP only among obese women. This population-based study corroborates findings from clinical studies suggesting that even among individuals with obesity, higher MS might help adults to reduce cardiometabolic risk. HighlightsMuscle strength levels were directly associated with better prognosis in relation to cardiometabolic variables in individuals with or without abdominal obesity.Among men with abdominal obesity, to have higher values of muscle strength were associated with lower values of diastolic blood pressure, C-reactive protein, triglycerides, cholesterol and HOMA-IR.Higher muscle strength levels were inversely associated with C-reactive protein among women with abdominal obesity; Higher muscle strength might help adults to reduce cardiometabolic risk.
