Prospective associations between hand grip strength and subsequent depressive symptoms in men and women aged 50 years and older: insights from the Survey of Health, Aging, and Retirement in Europe.

ABSTRACT:

Introduction

In previous cross-sectional and longitudinal studies, depressive symptoms have been associated with lower hand grip strength (HGS), which is a convenient measure of overall muscular strength and serves as a marker of poor health. Most studies have considered low sample sizes or highly selective patient cohorts.

Methods

We studied the association between depressive symptoms (EURO-D) and HGS in three waves from the cross-national panel dataset Survey of Health, Aging, and Retirement in Europe (SHARE). Linear regressions and Generalized Estimating Equations (GEE) were conducted to determine factors associated with depressive symptoms and investigate whether HGS predicts future depressive symptoms.

Results

Cross-sectional HGS explained 7.0% (Wave 4), 5.7% (Wave 5), and 6.4% (Wave 6) of the EURO-D variance. In the GEE, we analyzed people without depression in Wave 4 (N = 39,572). HGS predicted future EURO-D (B = -0.21, OR = 0.979, 95%CI (0.979, 0.980), p < 0.001) and remained a significant predictor of future depressive symptoms after adjustment for age, sex, psychosocial and physical covariates.

Discussion

Muscle strength is a known marker for physical health, but a relation with mental health has also been proposed previously. This study confirmed the link between HGS and depressive symptoms in men and women aged ≥50 years in a large longitudinal dataset. Further research is required to understand the mechanisms behind this link to determine whether HGS can serve as a specific marker of depressive symptomology, or whether they coexist due to common underlying disease processes.

Project description:In the scientific literature, there is much evidence of a relationship between age and dexterity, where increased age is related to slower, less nimble and less smooth, less coordinated and less controlled performances. While some suggest that the relationship is a direct consequence of reduced muscle strength associated to increased age, there is a lack of research that has systematically investigated the relationships between age, strength and hand dexterity. Therefore, the aim of this study was to examine the associations between age, grip strength and dexterity. 107 adults (range 18-93 years) completed a series of hand dexterity tasks (i.e. steadiness, line tracking, aiming, and tapping) and a test of maximal grip strength. We performed three phases of analyses. Firstly, we evaluated the simple relationships between pairs of variables; replicating the existing literature; and found significant relationships of increased age and reduced strength; increased age and reduced dexterity, and; reduced strength and reduced dexterity. Secondly, we used standard Multiple Regression (MR) models to determine which of the age and strength factors accounted for the greater variance in dexterity. The results showed that both age and strength made significant contributions to the data variance, but that age explained more of the variance in steadiness and line tracking dexterity, whereas strength explained more of the variance in aiming and tapping dexterity. In a third phase of analysis, we used MR analyses to show an interaction between age and strength on steadiness hand dexterity. Simple Slopes post-hoc analyses showed that the interaction was explained by the middle to older aged adults showing a relationship between reduced strength and reduced hand steadiness, whereas younger aged adults showed no relationship between strength and steadiness hand dexterity. The results are discussed in terms of how age and grip strength predict different types of hand dexterity in adults.

Project description:Mechanical loading by muscles elicits anabolic responses from bone, thus age-related declines in muscle strength may contribute to bone fragility in older adults. We used high-resolution peripheral quantitative computed tomography (HR-pQCT) to determine the association between grip strength and distal radius bone density, size, morphology, and microarchitecture, as well as bone strength estimated by micro-finite element analysis (μFEA), among older men and women. Participants included 508 men and 651 women participating in the Framingham Offspring Study with grip strength measured in 2011-2014 and HR-pQCT scanning in 2012-2015. Separately for men and women, analysis of covariance was used to compare HR-pQCT measures among grip strength quartiles and to test for linear trends, adjusting for age, height, weight, smoking, and physical activity. Mean age was 70 years (range, 50-95 years), and men had higher mean grip strength than the women (37 kg vs. 21 kg). Bone strength estimated by μFEA-calculated failure load was higher with greater grip strength in both men (p < 0.01) and women (p = 0.04). Higher grip strength was associated with larger cross-sectional area in both men and women (p < 0.01), with differences in area of 6% and 11% between the lowest to highest grip strength quartiles in men and women, respectively. Cortical thickness was positively associated with grip strength among men only (p = 0.03). Grip strength was not associated with volumetric BMD (vBMD) in men. Conversely, there was a trend for lower total vBMD with higher grip strength among women (p = 0.02), though pairwise comparisons did not reveal any statistically significant differences in total vBMD among grip strength quartiles. Bone microarchitecture (cortical porosity, trabecular thickness, trabecular number) was not associated with grip strength in either men or women. Our findings suggest that the positive association between hand grip strength and distal radius bone strength may be driven primarily by bone size. © 2021 The Authors.

Project description:Background:Hand grip strength (HGS) is gaining the attention of researchers and clinicians, including geriatricians as a readily available, inexpensive, and useful measure of muscle strength. Objective:To identify the indicators of abnormal HGS as measured by a Jamar handheld dynamometer in community-dwelling Egyptian senior citizens. Study Design:The study was approved by the relevant ethical committee. This cross-sectional study included 200 randomly selected older adults of both sexes who attended geriatric and internal medicine outpatient clinics. Informed consent was obtained, and comprehensive geriatric assessment was performed, including assessment of the health-related quality of life by the 12-Item Short-Form Health Survey (SF-12). Measurement:HGS was measured, and values of 20 kg or less in females and 30 kg or less in males were considered abnormal. Statistical Methods:IBM SPSS statistics v25.0 was used for data analysis. Data were expressed as the mean ± SD for quantitative parametric measures and as the number and percentage for categorical data. Student's t-test, the chi-squared test, the diagnostic validity test, and multiple logistic regression analysis were performed. The ROC (receiver operating characteristic) curve was constructed, and the AUC (area under the curve) was also calculated. Results:The subjects' ages ranged from 60 to 95 years with a mean age of 69 ± SD 7.1 years. The sample consisted of 117 females (58.5%) and 83 males (41.5%). The chi-squared test showed that abnormal findings for grip strength were significantly more common among females than males (67.7% vs 32.3%). Student's t-test showed that both height and weight were significantly lower among subjects with abnormal than normal HGS, while body mass index (BMI) showed a non-significant difference. Stepwise multiple logistic regression analysis showed that there was no actual relationship between sex and abnormality of HGS. Conclusion:The best indicators of abnormal HGS were found to be a general health score below 25 points on the SF-12 and a height of less than 178 cm. As the values of general health and height decrease below those cut-off points, HGS decreases as well, and vice versa.
