Is waist-to-height ratio a better predictor of hypertension and type 2 diabetes than body mass index and waist circumference in the Chilean population?
Objective: The aim of this study was to identify which anthropometric measurement (body mass index [BMI], waist circumference [WC], or waist-to-height ratio [WHtR]) is a better predictor of type 2 diabetes and hypertension in the Chilean population. Methods: The study included 13 044 participants (59.7% women) from the Chilean National Health Surveys conducted in 2003, 2009-2010, and 2016-2017. BMI, WC, and WHtR were the anthropometric measurements evaluated. Hypertension was defined as systolic blood pressure ≥140 mm Hg and diastolic blood pressure -90 mm Hg or on medication for hypertension. Diabetes was defined as fasting glucose -7 mmol/L or on medication for diabetes. The receiver operating characteristics (ROC) curve and the area under curve (AUC) were computed to derive the specificity and sensitivity using a bootstrapping approach. Results: Compared with BMI and WC, WHtR was the anthropometric measurement with the highest AUC curve in both sexes for hypertension (AUC for women: 0.70; 95% confidence interval [CI], 0.67-0.73; AUC for men: 0.71; 95% CI, 0.69-0.74) and diabetes (AUC for women: 0.71; 95% CI, 0.66-0.77; AUC for men: 0.71; 95% CI, 0.67-0.76). The sex-specific cutoff points of WHtR to predict hypertension were 0.59 and 0.55 for women and men, respectively. Those used to predict diabetes were 0.60 and 0.58 for women and men, respectively. Conclusion: WHtR was a better predictor of hypertension and diabetes than BMI and WC in Chile. The definition of cutoff points specific for the Chilean population could be implemented in future screening programs aiming to identify high-risk individuals.
Asociación de un índice de estilos de vida saludable con factores de riesgo cardiovascular en población chilena
Background: Healthy lifestyles are associated with a better metabolic and cardiovascular health profile. Aim: To investigate the association between a lifestyle score and cardiovascular risk in Chilean adults. Material and Methods: A healthy lifestyle score was derived for 2,774 participants in the Chilean National Health Survey 2009-2010 and based on seven modifiable behaviors (salt intake, fruit and vegetable intake, alcohol consumption, sleep duration, smoking, physical activity and sedentary behaviors). A high score represented a healthier lifestyle whereas a low score represents an unhealthy lifestyle. The association between the lifestyle score and cardiovascular risk factors (obesity, hypertension, diabetes, dyslipidemia and metabolic syndrome), was explored using logistic regression models. Results: One quartile increment in the healthy lifestyle score was associated with a lower risk for obesity (Odds ratio (OR): 0.82 [95% confidence intervals (CI): 0.75 to 0.90], p < 0.01), central obesity (OR: 0.88 [95% CI: 0.81 to 0.96], p < 0.01), diabetes (OR: 0.84 [95% CI: 0.75 to 0.95], p < 0.04) and dyslipidemia (OR: 0.90 [95% CI: 0.83 to 0.98], p = 0.01). These results were independent of major confounding factors. Conclusions: The adherence to a healthy lifestyle is associated with lower cardiovascular risk.
Menopausia y factores de riesgo cardiovascular en mujeres chilenas
Background: Menopause exposes women to an increased cardiovascular risk. Aim: To determine the association between menopause and cardiovascular risk factors in Chilean adult women using data from the National Health Survey (NHS) 2016-2017. Material and Methods: Data from 2,139 women over 40 years of age participating in the NHS 2016-2017, with information about menopause and cardiovascular risk factors was used. Expansion factors were applied to this sample, obtaining an expanded sample of 3,733,191 participants. Laboratory values (blood glucose, triglycerides, HDL and total cholesterol) and anthropometric measurements (body weight, height and waist circumference) were analyzed. The presence of hypertension, diabetes, and metabolic syndrome (MetS) were also recorded. Results: Sixty seven percent of surveyed women were menopausal and had higher systolic blood pressure than non-menopausal participants. Menopause was significantly associated with hypertension (Odds ratio (OR): 2.43 [95% confidence intervals (CI): 1.71; 3.45], p < 0.01) and diabetes (OR: 2.05 [95% CI: 1.32; 3.19], p < 0.01). However, no association was observed with obesity, abdominal obesity or MetS. Conclusions: In these women, a positive association was identified between menopause and hypertension as well as diabetes.
