Quality of life and physical activity in prefrail individuals over 70 years in primary care

Abstract

Background: Frailty is an increasing problem among the elderly people and it is more frequent in women. Physical activity improves either the function and quality of life. Given the diferences reported by the literature about the quality of life perception and the physical activity practice between men and women, the aim of this study is to analyze the association between health related quality of life (HRQoL) and physical activity in a pre-frail population and to study its relationship with gender.

Methods: Descriptive study in pre-frail individuals over 70 years old assigned to twelve primary care health centers carried out between 2018 Jun and 2020 March in Madrid. The studied variables were registered by clinical interview: Physical activity (Yale), HRQoL (EQ-5D-3L), sociodemographic and clinical variables (comorbidity, depression and pain). Descriptive analysis and multiple linear regression for the whole population and stratified by gender, using the quality of life as dependent variable.

Results: The study involved 206 pre-frail individuals (152 women) wih an average age of 78 years. Women had less comorbidity (32.3% versus 55.6%) but more pain (60.5% versus 44.4%) than men. The median of physical activity was 40 points (55.9% of that score was attributable to relaxed walk). HRQoL was 0.74 in utility score and 68 in the EQ-VAS. No differences were found by gender. To walk more than 5 hours a week was found associated with better quality of life by EQ-5D utility score (0.08, IC95%: 0.03 to 0.14), and by EQ-VAS score (5.38, IC95%: 0.25 to 10.51). 

Conclusions: Physical activity was associated to better quality of life in a pre-frail population of individuals older than 70 years old.
