Association between changes in working status and hand-grip strength among Korean middle-aged and older adults: a longitudinal panel study

Abstract

We investigated the association between working status changes and hand-grip strength (HGS) among middle-aged and older Korean adults using data from the 2006–2018 Korean Longitudinal Study of Aging. After excluding those with less than normal HGS in the baseline year, newly added panels, and missing values, 3843 participants (2106 men; 1737 women) were finally included. After adjusting for potential confounders, we used a 2-year lagged multivariable generalized estimating equation model to examine this association longitudinally. Men who quit working or who continued to be non-working were more likely to have lower HGS than those who continued to work (working → non-working, adjusted odds ratio [OR]: 1.47, 95% confidence interval [CI] 1.26–1.70; non-working → non-working, adjusted OR: 1.52, 95% CI 1.34–1.72). Compared to women who continued to work, the other three groups showed high ORs with low HGS (working → non-working, adjusted OR: 1.19, 95% CI 1.01–1.40; non-working → working, adjusted OR: 1.18, 95% CI 0.98–1.42; non-working → non-working, adjusted OR: 1.38, 95% CI 1.22–1.56). Middle-aged and older adults whose working status changed to non-working were at higher risk of reduced HGS than others and required muscular strength training interventions to improve HGS and prevent sarcopenia.

Examining factors contributing to the socioeconomic inequalities in handgrip strength among older adults in India: a decomposition analysis

“…In their study on older Indonesians, Pengpid and Peltzer observed a statistically significant positive link between education and HGS among men 15 . Likewise, the Arokiasamy et al found a significant and positive association between education and wealth and HGS among older adults in India 12 ; and, in another study among older Koreans, researchers found that those who transitioned from working to non-working status reported an increased risk of weak HGS 17 .…”

Investigating the Influence of Working Status Changes on Physical Activity and Non-Communicable Diseases in Korean Middle-Aged and Older Adults: Insights from a Longitudinal Panel Study

“…Within the spectrum of age demographics, individuals classi ed as middle-aged and older adults undergo more frequent alterations in their employment status compared to their younger counterparts. This phenomenon can be ascribed to various factors, including retirement, career transitions, or other employment-related factors, all of which have implications for healthrelated outcomes [17]. The repercussions of such uctuations wield a profound impact on their overall lives and well-being, rendering them potentially more responsive to variations in work status as they progress with age.…”

A Metamaterial Computational Multi‐Sensor of Grip‐Strength Properties with Point‐of‐Care Human‐Computer Interaction

“…[4,8,9] For instance, the middle-aged and older adults who switch from working to non-working status are at a higher risk of reduced grip strength than others and require muscle strength training interventions to improve grip strength and prevent sarcopenia. [37] Future neurorehabilitation therapies also focus on the competence to precisely control the decline in grip strength and the improvement of movement quality to some extent. [38] Exergames inherently involve cognitive training and even simple exergames without explicit cognitive demands essentially require cognitive processing.…”
