摘要

Life habits can influence the aging process. However, there remains a gap in how these factors can associate frailty, independence in activities of daily living, depression and quality of life in older adults. (1) To develop an index to synthesize modifiable lifestyle factors of older adults of middle-income countries; (2) to check the relationship and the association of this index with frailty, independence in daily activities, depression and quality of life. This exploratory, cross-sectional, quantitative study included 192 community-dwelling older adults aged 60 to 96 years (M = 70.66, SD = 7.71), of whom 124 (64.6%) were women. The criteria established for the index, based on the literature, were: (1) smoking, (2) Alcohol consumption, (3) Nutrition, (4) Physical Activity, and (5) Sleep quality. Multi-attribute utility theory was applied to determine the Multicriteria Index (MI) of modifiable lifestyle factors. Pearson’s correlation, simple linear regression, and multivariate analyses were conducted to examine the association between the index and clinical outcomes. The index was correlated and associated with frailty, depression, independence in daily activities and quality of life (p < 0.05). The multivariate linear regression analysis demonstrated that modifiable lifestyle factors associated with a healthy lifestyle were linked to 22% of the variation in higher quality-of-life scores and lower depression scores (p < 0.05). Modifiable lifestyle factors for a healthy lifestyle have a positive factor in contributing to overall quality of life in the aging process and healthy lifestyle habits can promote the health of older adults.
