Resumen
Objective
This study investigated the individual and combined association of walking pace and grip strength with all-cause mortality in Chilean adults.
Study design 8813 participants (54.6 % women) from the MAUCO population-based cohort were included in this prospective study.
Main outcome measures
Individual and combined associations of grip strength (normal or low grip) and walking pace (normal or slow walking) with all-cause mortality were investigated using Cox proportional-hazard models. Analyses were adjusted for sociodemographic, lifestyle, and health-related factors.
Results
Over a median follow-up of 4.74 years, 151 and 206 participants included in the analyses of walking pace and grip strength died. Individuals with low grip strength had a risk of dying 2.40 times (95 % CI: 1.64 to 3.51) higher than their counterparts with normal grip strength. Similar results were identified for slow walkers (HR: 1.77 [95 % CI: 1.25 to 2.50]). When the two factors were combined and the associations investigated, individuals with normal walking pace but with low grip strength had a higher risk of all-cause mortality than those with normal walking pace and normal grip strength (HR: 3.56 [95 % CI: 1.99 to 6.36]). The associations remained even after including a 1- and 2-year landmark period in the nalyses.
Conclusions
Slow walking pace and low grip strength were associated with a higher risk of mortality (both in isolation and combined). These factors might be early markers of all-cause mortality, and should be measured more frequently in middle-aged and older adults in clinical practice.
