“…For example, previous research has revealed that a temporal, bidirectional association exists for HGS and cognitive function. 94,95 Similarly, a longitudinal, bidirectional association may exist between HGS and metabolic diseases such as diabetes. 96,97 Such findings indicate that when paralleling associations exist, losses of function in one factor could lead to losses in the other.…”

What are the association patterns between handgrip strength and adverse health conditions? A topical review

Measures of handgrip strength can be used to conveniently assess overall muscle strength capacity. Although stand-alone measures of handgrip strength provide robust health information, the clinical meaningfulness to determine prevention and treatment options for weakness remains limited because the etiology of muscle weakness remains unclear. Moreover, clinical outcomes associated with handgrip strength are wide-ranging. Therefore, disentangling how handgrip strength is associated with health conditions that are metabolically or neurologically driven may improve our understanding of the factors linked to handgrip strength. The purpose of this topical review was to highlight and summarize evidence examining the associations of handgrip strength with certain health outcomes that are metabolically and neurologically driven. From this perusal of the literature, we posit that stand-alone handgrip strength be considered an umbrella assessment of the body systems that contribute to strength capacity, and a panoptic measurement of muscle strength that is representative of overall health status, not a specific health condition. Recommendations for future strength capacity–related research are also provided.

“…In a Korean longitudinal study [5] with elderly women over 65 years of age, HGS was associated with a reduced risk of cognitive impairment in obese women, but not in non-obese women. And in another longitudinal Korean aging study [29], which assessed the relationship between HGS and the cognitive function, a significant bidirectional relationship was observed between these variables; and the authors suggested that this should be better elucidated in further investigations. HGS could also be used in the assessment of cognitive status, and the strength capacity and cognitive function could parallel each other [30], where the functionality loss in one factor, could predict the loss of functionality in the other, as shown in that study conducted with elderly Americans [30].…”

To evaluate the contribution of handgrip strength (HGS) in outpatient care for elderly patients with Alzheimer's disease (AD). Crosssectional study, with AD patients, >65 years of age, who underwent cognitive, nutritional and HGS assessment, International Physical Activity Questionnaire (IPAQ-SF) and Disability Assessment in Dementia (DAD). The data were compared to a similar control group (CG) composed of 51 elderly people, with p <0.05. The 43 elderly people with AD exhibited lower HGS scores when compared to the CG (13.4±8.2 vs 17.5±8.0; p=0.008, Mann-Whitney). There was no difference in HGS according to the severity of dementia, cognitive aspects, the IPAQ-SF and in the activities of daily living in the DAD. Higher HGS values were associated with males and younger age. There was a correlation with some anthropometric indicators. HGS was significantly lower in elderly people with AD. In Alzheimer's disease, higher HGS values were associated with males, younger age and some anthropometric indicators I.

“…We assessed cognitive impairment using the Korean version of the Mini-Mental State Examination (K-MMSE), a brief but reasonably accurate measure of cognitive function which has been previously shown to have sensitivity/specificity rates of above 90% (Folstein, Folstein, and McHugh 1975). Keeping in line with prior studies, we considered those who scored below 24 points (out of a possible 30 points) as cognitively impaired (Kim et al 2019; Lyu and Kim 2016). This categorization was systematically validated for use in the Korean context (Kang, Na, and Hahn 1997) and has been widely adopted in prior research (Choi et al 2016; Kim et al 2017, 2019).…”

Productive Activities and Risk of Cognitive Impairment and Depression: Does the Association Vary by Gender?

We examine how labor together with social participation protects against cognitive impairment and depression, with a focus on gender differences. Data are drawn from four waves of the Korean Longitudinal Study of Aging (2006–2012). Both paid work and unpaid work are considered labor participation. Social participation includes the frequency of participation in formal social institutions, religious groups, grandparenting, and interactions with family and friends. Using growth curve models, we find that social and labor participation are independently associated with outcomes and effects vary by gender. Religious group activity was beneficial only for women, whereas inability to work was detrimental for men only. Informal social gatherings and labor participation, paid or unpaid, were beneficial for both genders. Findings on gender differences highlight how social identities can shape social roles and confine activity space, and productive engagement, affecting outcomes for mental health in later life.
