Comparing measures of overall and central obesity in relation to cardiometabolic risk factors among US Hispanic/Latino adults.

Abstract

US Hispanics/Latinos have high prevalence of obesity and related comorbidities. We compared overall and central obesity measures in associations with cardiometabolic outcomes among US Hispanics/Latinos. Multivariable regression assessed cross-sectional relationships of six obesity measures with cardiometabolic outcomes among 16,415 Hispanics/Latinos aged 18-74 years. BMI was moderately correlated with waist-to-hip ratio (WHR; women, r = 0.37; men, r = 0.58) and highly correlated with other obesity measures (r ≥ 0.87) (P < 0.0001). All measures of obesity were correlated with unfavorable levels of glycemic traits, blood pressure, and lipids, with similar r-estimates for each obesity measure (P < 0.05). Multivariable-adjusted prevalence ratios (PRs) for diabetes (women, 6.7 [3.9, 11.5]; men, 3.9 [2.2, 6.9]), hypertension (women, 2.4 [1.9, 3.1]; men, 2.5 [1.9, 3.4]), and dyslipidemia (women, 2.1 [1.8, 2.4]; men, 2.2 [1.9, 2.6]) were highest for individuals characterized as overweight/obese (BMI ≥ 25 kg/m(2)) and with abnormal WHR (women ≥0.85; men, ≥0.90), compared with those with normal BMI and WHR (P < 0.0001). Among normal-weight individuals, abnormal WHR was associated with increased cardiometabolic condition prevalence (P < 0.05), particularly diabetes (women, PR = 4.0 [2.2, 7.1]; men, PR = 3.0 [1.6, 5.7]). Obesity measures were associated with cardiometabolic risk factors to a similar degree in US Hispanics/Latinos. WHR is useful to identify individuals with normal BMI at increased cardiometabolic risk.
