Mental Health and Handgrip Strength Among Older Adults: A Nationwide Study

Handgrip strength is used as an important indicator of health in older adults. We aimed to explore the association between stress, depression, and suicidal ideation and handgrip strength among older adults. We conducted this cross-sectional study involving 1254 individuals (aged ≥65 years), using data from the 2015 Korean National Health and Nutrition Examination Survey VI. We used logistic regression analysis to examine associations between handgrip strength and mental health. Among mental health factors, a significant difference was noted between stress and handgrip strength among the older adults. After adjusting for confounding factors, the odd ratio (OR) of stress among older adults with low handgrip strength was statistically significant in Models 1 (1.61 (95% CI: 1.01–2.57)) and 2 (1.59 (95% CI: 1.01–2.52)) but not in Model 3 (1.52 (95% CI: .96–2.43)). No significant association was found between depression or suicidal ideation and handgrip strength. The risk of stress was 1.59-1.61 times higher in older adults with low handgrip strength, compared to that in older adults with normal handgrip strength. It is necessary to develop strategies aimed at managing stress among older adults with low handgrip strength and educating them about the importance of handgrip strength and exercises that increase handgrip strength.

Sex-Associated Differences in the Handgrip Strength of Elderly Individuals

This study aimed to identify sex-specific factors associated with handgrip strength in elderly individuals. The analysis cohort comprised 1,197 men and 1,384 women aged ≥65 years. In men, factors associated with low handgrip strength included advanced age; low body mass index; low frequency of performing flexibility exercises; limited self-care ability (which is a measure of the health-related quality of life); and the presence of diabetes, stroke, or osteoporosis (R² = 0.285, F = 7.52, p < .001). In women, the factors included advanced age, low body mass index, low frequency of performing muscle strengthening exercises, stress, and osteoarthritis (R² = 0.225, F = 4.17, p < .001). Effective health-promoting interventions for elderly individuals require the development of individualized programs that enhance handgrip strength while considering sex-related factors.

Quality of life and subjective health status according to handgrip strength in the elderly: a cross-sectional study

OBJECTIVES

The purpose of this cross-sectional study was to examine potential associations between handgrip strength and health-related quality of life, or subjective health status, in the elderly.

METHOD

We performed secondary data analysis on 2377 elderly individuals aged >65 years. Raw data from the Korea National Health and Nutrition Examination Survey VI (2014-2015), were drawn from a representative national sample.

RESULTS

Of those aged ≥65 years or older, 25.4% had low handgrip strength. After adjusting for confounding variables, the odds ratios of elderly individuals with low handgrip strength were 1.30 (95% confidence interval [CI]: 1.00-1.69) for mobility, 2.18 (95% CI: 1.47-3.22) for self-care, 1.70 (95% CI: 1.30-2.23) for usual activities, 1.30 (95% CI: 1.01-1.67) for pain/discomfort, 1.03 (95% CI: 0.74-1.44) for anxiety/depression, 1.44 (95% CI: 1.10-1.87) for the EQ-5D index, and 1.37 (95% CI: 1.08-1.73) for subjective health status.

CONCLUSION

Health-related quality of life and subjective health status differ according to handgrip strength. Therefore, handgrip strength should be addressed to improve quality of life in elderly individuals. Elderly individuals require exercise education and adequate nutritional intake to increase handgrip strength.
