Abstract

Introduction: Lifestyle-related habits have a strong influence on morbidity and mortality world- wide. This study investigates the association between a multidimensional healthy lifestyle score and all-cause mortality risk, including in the score some less-studied lifestyle-related factors. Methods: Participants (n=20,094) of the Seguimiento Universidad de Navarra cohort were fol- lowed up from 1999 to 2018. The analysis was conducted in 2019. A 10-point healthy lifestyle score previously associated with a lower risk of major cardiovascular events was applied, assigning 1 point to each of the following items: never smoking, moderate-to-high physical activity, moderate-to-high Mediterranean diet adherence, healthy BMI, moderate alcohol consumption, avoidance of binge drinking, low TV exposure, short afternoon nap, time spent with friends, and working ≥40 hours per week. Results: During a median follow-up of 10.8 years, 407 deaths were documented. In the multivari- able adjusted analysis, the highest category of adherence to the score (7−10 points) showed a 60% lower risk of all-cause mortality than the lowest category (0−3 points) (hazard ratio=0.40, 95% CI=0.27, 0.60, p<0.001 for trend). In analyses of the healthy lifestyle score as a continuous variable, for each additional point in the score, a 18% relatively lower risk of all-cause mortality was observed (adjusted hazard ratio=0.82, 95% CI=0.76, 0.88). Conclusions: Adherence to a healthy lifestyle score, including some less-studied lifestyle-related factors, was longitudinally associated with a substantially lower mortality rate in a Mediterranean cohort. Comprehensive health promotion should be a public health priority. Am J Prev Med 2020;59(2):e59−e67. © 2020 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.
