Associations between upper limb flexibility and all-cause mortality in the oldest-old.

ABSTRACT:

Background

Upper limb flexibility (ULF) is a simple and feasible measure of physical function in long-lived population. This study aimed to explore the association of ULF with all-cause mortality in community-dwelling oldest-old in China.

Methods

A total of 21 861 older adults aged ≥80 years were enrolled from five waves of the Chinese Longitudinal Healthy Longevity Survey. The assessment of ULF at baseline involved three objective physical tasks (touching the root of the neck, touching the lower back, and raising arms vertically). All participants were followed up until 2018, during which survival information was collected. Cox proportional hazards regression model was used to analyse the association between ULF and all-cause mortality. Demographic characteristics, health b
