Asociación de un índice de estilos de vida saludable con factores de riesgo cardiovascular en población chilena / Association of a healthy lifestyle index with cardiovascular risk factors in Chileans adults

ABSTRACT

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.
