Thresholds of handgrip strength for all-cause mortality in patients with chronic kidney disease: a secondary systematic review with dose-response meta-analysis. Ren Fail 2024; 46:2305855. [PMID: 38247440 PMCID: PMC10810645 DOI: 10.1080/0886022x.2024.2305855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 01/10/2024] [Indexed: 01/23/2024] Open
Abstract
BACKGROUND Although handgrip strength is associated with all-cause mortality in patients with chronic kidney disease (CKD), whether this relationship is dose-related is unknown. Therefore, we examined dose-response relationships between handgrip strength and all-cause mortality in CKD patients based on previous studies by meta-analysis. METHODS Data sources included three electronic databases (PubMed, Web of Science, and Embase) from inception through October 2023. The included cohort was a CKD population not limited to disease stage, and their handgrip strength was objectively measured. Two researchers independently screened studies, extracted data, and assessed the risk of bias. We utilized estimates of handgrip strength categories using robust-error meta-regression (REMR), pooled study-specific estimates, and established dose-response relationships. Outcomes of interest included only all-cause mortality. RESULTS A total of 18 studies with 4810 participants (aged 47-71 years) were included. REMR modeling showed a U-shaped trend of association between handgrip strength and all-cause mortality in patients with CKD. Higher handgrip strength values, from 10 kg to approximately 28 kg, were associated with lower mortality risk. After that, the risk of death increased slightly. CONCLUSION A U-shaped association exists between handgrip strength and all-cause mortality risk in CKD patients. Future studies with quantitative measurements for each CKD stage will help to determine precise relative risk estimates between handgrip strength and mortality risk in patients with different stages of CKD.

J Affect Disord 2024; 363:401-408. [PMID: 39029688 DOI: 10.1016/j.jad.2024.07.120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 06/30/2024] [Accepted: 07/16/2024] [Indexed: 07/21/2024]
Abstract
BACKGROUND Handgrip strength (HGS) weakness and asymmetry were recently reported to be associated with age-related health conditions. However, little is known about their combined effects on depression. We aimed to explore the joint association of HGS asymmetry and weakness with depressive symptoms in Chinese middle and older aged population. METHODS 8700 participants aged ≥45 years were enrolled from China Health and Retirement Longitudinal Study (2015-2018). HGS weakness was determined as maximal HGS < 28 kg in males and <18 kg in females. HGS asymmetry was measured by HGS ratio and was defined using two different rules. Specifically, HGS ratio < 0.90 or >1.10 (10 % rule) and <0.80 or >1.20 (20 % rule) were considered as asymmetry. Participants were classified into four groups: normal and symmetric HGS, asymmetry only, weakness only, and both weakness and asymmetry. Depressive symptoms were assessed by the 10-item Center for Epidemiologic Studies Depression Scale, with scores ≥12 defined as depression. The logistic regression and multiple linear regression models were conducted to estimate the associations between HGS status and depressive symptoms. RESULTS The three-year incidence of depression was 19.2 %. After adjusting for covariates, compared to normal and symmetric HGS, participants with both HGS asymmetry and weakness showed the greatest risk of incident depression (10 % rule: OR 1.55, 95 % CI 1.19-2.02; 20 % rule: OR 1.71, 95 % CI 1.16-2.50). The coexistence of asymmetry and weakness was related to a significant increase in depression score (10 % rule: β 0.96, 95 % CI 0.38-1.54; 20 % rule: β 0.94, 95 % CI 0.08-1.81). The complete case analysis supported the results, and the associations were not modified by age, sex, and hand dominance. LIMITATIONS Depressive assessment was based on self-reported screening instrument. CONCLUSIONS The presence of both HGS asymmetry and weakness was associated with a higher risk of depression. Examining HGS asymmetry along with weakness may aid in identifying individuals at risk of depression to enable early interventions.

Handgrip strength and mortality in a cohort of kidney failure patients: Comparative analysis of different normalization methods. Nutrition 2024; 125:112470. [PMID: 38788512 DOI: 10.1016/j.nut.2024.112470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 04/01/2024] [Accepted: 04/14/2024] [Indexed: 05/26/2024]
Abstract
OBJECTIVES Reduced handgrip strength (HGS) is associated with adverse clinical outcomes. We analyzed and compared associations of HGS with mortality risk in dialysis patients, using different normalization methods of HGS. METHODS HGS and clinical and laboratory parameters were measured in a cohort of 446 incident dialysis patients (median age 56 y, 62% men). The area under the receiver operating characteristic curve (AUROC) was used to compare different normalization methods of HGS as predictors of mortality: absolute HGS in kilograms; HGS normalized to height, weight, or body mass index; and HGS of a reference population of sex-matched controls (percentage of the mean HGS value [HGS%]). Multivariate linear regression analysis was used to assess HGS predictors. Competing risk regression analysis was used to evaluate 5-year all-cause mortality risk. Differences in survival time between HGS% tertiles were quantitated by analyzing the restricted mean survival time. RESULTS The AUROC for HGS% was higher than the AUROCs for absolute or normalized HGS values. Compared with the high HGS% tertile, low HGS% (subdistribution hazard ratio [sHR] = 2.36; 95% CI, 1.19-3.70) and middle HGS% (sHR = 1.79; 95% CI, 1.12-2.74) tertiles were independently associated with higher all-cause mortality and those with high HGS% tertile survived on average 7.95 mo (95% CI, 3.61-12.28) and 18.99 mo (95% CI, 14.42-23.57) longer compared with middle and low HGS% tertile, respectively. CONCLUSIONS HGS% was a strong predictor of all-cause mortality risk in incident dialysis patients and a better discriminator of survival than absolute HGS or HGS normalized to body size dimensions.

Abstract
OBJECTIVE The aim of this study was to investigate the combined effect of handgrip strength (HGS) and obesity phenotype on the risk of stroke in Chinese middle-aged and elderly people. METHODS The data was used from the China Health and Retirement Longitudinal Study (CHARLS). Middle-aged and older adults who participated in surveys between 2011 and 2018 were included in the study. They were divided into 4 different types of obesity phenotypes based on obesity and metabolic status: metabolically healthy non-overweight/obesity (MHNO), metabolically healthy overweight/obesity (MHO), metabolically abnormal non-overweight/obesity (MANO), and metabolically abnormal overweight/obesity (MAO). The HGS level was divided into low and high groups according to the median values. Cox proportional risk regression model was used to analyze the joint effect of HGS and obesity phenotype on the risk of stroke among participants. RESULTS A total of 7904 participants aged 58.89±9.08 years were included in this study. After adjusting for potential confounders, high HGS&MHO (HR=1.86, 95 % CI=1.12-3.09), high HGS&MANO (HR=2.01, 95 %CI=1.42-2.86), high HGS&MAO (HR=2.01, 95 % CI=1.37-2.93), low HGS&MHNO (HR=1.57, 95 % CI=1.00-2.46), low HGS&MHO (HR=2.09, 95 % CI=1.29-3.38), low HGS&MANO (HR=2.02, 95 % CI=1.35-3.03), and low HGS&MAO (HR=2.48, 95 % CI=1.72-3.58) group had significantly higher risks of stroke than the high HGS&MHNO group. CONCLUSION The coexistence of metabolically unhealthy and low HGS can synergistically increase the risk of stroke in Chinese middle-aged and elderly people.

Predictors of the onset of low handgrip strength in Europe: a longitudinal study of 42,183 older adults from 15 countries. Aging Clin Exp Res 2024; 36:162. [PMID: 39110364 PMCID: PMC11306649 DOI: 10.1007/s40520-024-02800-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 06/25/2024] [Indexed: 08/10/2024]
Abstract
OBJECTIVES A low handgrip strength (HGS) is a significant risk factor for multiple diseases. However, most relevant studies investigate the complications of a low HGS, while the risk potential of causative factors of low HGS remain poorly characterized. METHODS We investigated the potentials of quality of life, depression, dyslipidaemia, diabetes mellitus, cancer, Alzheimer's disease, stroke, frailty, and difficulties performing daily activities in predicting low HGS (≤ 27 kg for men, ≤ 16 kg for women) in European older adults aged 50 or above from 15 countries (n = 42,183). All data was collected from four successive waves of survey of health, ageing, and retirement in Europe (SHARE) conducted between 2013 and 2020. Logistic models are applied, and estimated effects are presented as odds ratios and probabilities. RESULTS Collectively, 3016 participants (men; n = 1395; 7.38%, women; n = 1621, 6.97%) developed low HGS during the 6.5 years study period. After adjusting for covariables, we identified an advancing age (1.6-48.1% points higher risk of low HGS), male gender (1.0%-point higher risk of low HGS), lower quality of life (1.6%-point higher), and stroke (1.5%-points) as significant risk factors for low HGS. We also found a dose-dependent association of Euro-D depression scores with the risk of low HGS, as the higher scores were associated with between 0.6- and 2.3%-points higher risk of developing low HGS than participants without depression. Among physical performance indicators, difficulty climbing stairs (2.0%-points higher low HGS risk) or rising from a chair (0.7%-points) were significantly associated with developing low HGS. Lastly, frailty (0.9%-points higher risk of low HGS) and the fear of falling down (1.6%-points higher risk) also increased the risk of developing low HGS. CONCLUSION Altogether, we report several risk factors for developing low HGS. Our observations may help evaluating and monitoring high-risk population for developing low HGS in pre-clinical settings.

Association of dietary patterns with sarcopenia in adults aged 50 years and older. Eur J Nutr 2024; 63:1651-1662. [PMID: 38568294 PMCID: PMC11329607 DOI: 10.1007/s00394-024-03370-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 03/01/2024] [Indexed: 08/18/2024]
Abstract
PURPOSE Although numerous studies have investigated the impact of dietary factors on the prevention of decreased muscle mass and function, limited research has examined the relationship between dietary patterns and sarcopenia. This study aimed to assess the associations between dietary patterns, and sarcopenia, muscle strength, and mass in adults following a Mediterranean diet residing in southern Italian cities. METHODS This cross-sectional study utilized data from an existing database, comprising 528 individuals aged 50 years or older who underwent health-screening tests at the Clinical Nutrition Unit of the "R.Dulbecco" University Hospital. Strength was assessed through handgrip strength, and appendicular skeletal muscle mass was estimated using bioelectrical impedance analysis. Dietary intake information was collected through a food frequency questionnaire linked to the MetaDieta 3.0.1 nutrient composition database. Principal Component Analysis, a statistical technique identifying underlying relationships among different nutrients, was employed to determine dietary patterns. Multinomial logistic regression analysis was conducted to estimate the odds ratio for sarcopenia or low handgrip strength in relation to the lowest tertile of dietary pattern adherence compared to the highest adherence. RESULTS The participants had a mean age of 61 ± 8 years. Four dietary patterns were identified, with only the Western and Mediterranean patterns showing correlations with handgrip strength and appendicular skeletal muscle mass. However, only the Mediterranean pattern exhibited a correlation with sarcopenia (r = - 0.17, p = 0.02). The highest tertile of adherence to the Mediterranean dietary pattern demonstrated significantly higher handgrip strength compared to the lowest tertile (III Tertile: 28.3 ± 0.5 kg vs I Tertile: 26.3 ± 0.5 kg; p = 0.01). Furthermore, even after adjustment, the highest tertile of adherence to the Mediterranean pattern showed a significantly lower prevalence of sarcopenia than the lowest adherence tertile (4% vs 16%, p = 0.04). The lowest adherence to the Mediterranean dietary pattern was associated with increased odds of having low muscle strength (OR = 2.38; p = 0.03; 95%CI = 1.05-5.37) and sarcopenia (OR = 9.69; p = 0.0295; %CI = 1.41-66.29). CONCLUSION A high adherence to the Mediterranean dietary pattern, characterized by increased consumption of legumes, cereals, fruits, vegetables, and limited amounts of meat, fish, and eggs, is positively associated with handgrip strength and appendicular skeletal muscle mass. The highest adherence to this dietary model is associated with the lowest odds of low muscle strength and sarcopenia. Despite the changes brought about by urbanization in southern Italy compared to the past, our findings continue to affirm the superior benefits of the Mediterranean diet in postponing the onset of frailty among older adults when compared to other dietary patterns that are rich in animal foods.

Abstract
BACKGROUND There is a lack of consensus about the operationalization of vitality, which is one of the intrinsic capacity (IC) domains. In particular, no study has investigated whether cardiorespiratory fitness (CRF) can be considered a vitality indicator. OBJECTIVE To examine whether vitality is the upstream domain of IC, and establish the validity of CRF as a vitality indicator, using maximal oxygen consumption (VO2 max) as a representative. METHODS 561 older adults from a longitudinal cohort study were included. Variables under consideration were VO2 max, other IC domains, instrumental activities of daily living (IADL), and handgrip strength, which was considered an already validated indicator of vitality. Using handgrip strength as the reference point, path analyses were performed to examine whether VO2 max followed a similar hierarchical structure in predicting change in IADL difficulty through other IC domains. RESULTS The mean age of the participants was 75.5 years. The path model in which vitality was measured by VO2 max demonstrated adequate fit, which was similar to the model in which vitality was measured by handgrip strength. Regarding the path coefficients, the model using VO2 max demonstrated significant total and indirect effects. Notably, the indirect effect was due to the locomotor domain (standardized coefficient = -0.148, p < .001), but not the cognitive or psychological domain. CONCLUSION Vitality is the upstream domain of IC. VO2 max can be considered an indicator to operationalize the vitality concept.

Abstract
OBJECTIVE It is important to individualize nutrition therapy and to identify whether certain patient groups benefit from a specific intervention such as oral nutritional supplements (ONS). This study investigated whether patients with weak handgrip strength (HGS) benefit better from ONS administration in the Medication Pass Nutritional Supplement Program (MEDPass) mode regarding the individual coverage of energy and protein requirements throughout their hospitalization. METHODS A secondary analysis of the intention-to-treat data set of the randomized controlled MEDPass trial was conducted. Weak HGS was defined as <27 kg for men and <16 kg for women. Linear mixed-effect models adjusted for the stratification factors energy density of ONS and nutritional risk screening 2002 score were used to address the aim of the study. RESULTS We included 188 participants. Energy and protein coverage did not differ between the patients with weak or normal HGS depending on ONS administration mode (P = 0.084, P = 0.108). Patients with weak HGS and MEDPass administration mode tended to have the lowest energy and protein coverage (estimated mean, 77.2%; 95% confidence interval [CI], 69.3%-85% and estimated mean, 95.1%; 95% CI, 85.3%-105%, respectively). Patients with weak HGS and conventional ONS administration had the highest energy and protein coverage (estimated mean, 90%; 95% CI, 82.8%-97.2% and estimated mean, 110.2%; 95% CI, 101.3%-119%, respectively). CONCLUSION No clear recommendations regarding the mode of ONS administration depending on HGS can be made. In clinical practice, appetite and satiety in patients with weak HGS should be monitored, and the ONS administration mode should be adjusted accordingly.

Abstract
AIMS Patients with chronic obstructive pulmonary disease (COPD) frequently exhibit an inability to maintain postural balance. However, the contribution of increased intestinal permeability or leaky gut to the postural imbalance in COPD is not known. METHODS We measured plasma zonulin, a marker of leaky gut, with relevance to postural balance in male controls (n = 70) and patients with mild (n = 67), moderate (n = 66), and severe (n = 58) COPD. We employed a short physical performance battery to evaluate postural balance in supine, tandem, and semi-tandem positions. We also measured handgrip strength (HGS), gait speed, plasma c-reactive proteins (CRP), and 8-isoprostanes as potential mechanistic connections between postural imbalance and leaky gut. RESULTS COPD patients demonstrated higher plasma zonulin, CRP, and 8-isoprostanes levels and lower balance, HGS, and gait speed than controls (all p < 0.05). These findings were more robust in patients with moderate and severe than mild COPD. In addition, plasma zonulin exhibited significant potential in diagnosing poor balance, low HGS, and gait speed in COPD patients (all p < 0.05). We also found significant correlations of plasma zonulin with CRP and 8-isoprostanes, providing heightened inflammation and oxidative stress as mechanistic connections between leaky gut and postural imbalance. CONCLUSION Plasma zonulin may be helpful in evaluating postural imbalance in COPD patients. Repairing intestinal leaks can be a therapeutic target to improve postural control in COPD.

Abstract
BACKGROUND Cardiometabolic multimorbidity (CM) is emerging as a global health challenge. This study investigated the potential impact of muscle strength on the risk of CM in middle-aged and older Chinese adults. METHODS In total, 7610 participants were identified from the China Health and Retirement Longitudinal Study (CHARLS). Muscle strength was measured by absolute, relative grip strength (normalized for body mass index) and chair-rising time which were classified into three categories according to tertiles stratified by gender. Cox proportional hazards models were adopted to evaluate the effect of muscle strength on CM. RESULTS During follow-up, 235(3.76%) participants from none cardiometabolic diseases (CMD), 140 (19.23%) from diabetes, 119 (21.17%) from heart disease, and 22 (30.56%) from stroke progressed to CM. In participants who had low relative grip strength, CM was more likely to occur in individuals with heart disease at baseline (HR: 1.89, 95%CIs: 1.10 to 3.23). Those with high chair-rising time had a higher risk of CM than those with low chair-rising time in the individuals with diabetes (HR: 1.85, 95%CIs:1.20 to 2.86) and with heart disease (HR: 1.67, 95%CIs:1.04 to 2.70). However, we did not observe an association between muscle strength and CM in participants without CMD or with stroke at baseline. CONCLUSIONS In Chinese middle-aged and older adults, low relative grip strength was associated with a higher risk of CM in individuals with heart disease, while high chair-rising time was associated with a higher risk of CM in individuals with diabetes or heart disease.

Abstract
OBJECTIVES Metformin is an anti-diabetic drug with protective effects on skeletal muscle and physical capacity. However, the relevant mechanisms of action on skeletal muscle remain poorly understood. We investigated the potential contribution of neuromuscular junction (NMJ) degradation to skeletal muscle and physical capacity in geriatric men taking metformin. METHOD We recruited geriatric men for placebo (Age=73.1 ± 4.2 years, n = 70) and metformin (Age=70.1 ± 4.5 years, n = 62) groups. The patients in the metformin group received 1700 mg of metformin twice a day for 16 weeks. We measured plasma c-terminal agrin-fragment-22 (CAF22) and neurofilament light chain (NfL) as markers of neuromuscular junction (NMJ) degradation and neurodegeneration, respectively, with relevance to handgrip strength (HGS) and short physical performance battery (SPPB; a marker of physical capacity) in older adults taking metformin. These findings were associated with reduced oxidative stress in the metformin group. RESULTS At baseline, both groups had similar HGS, gait speed, SPPB scores, and plasma biochemistry. Metformin improved HGS, gait speed, and cumulative SPPB scores in geriatric men (all p < 0.05). Metformin also reduced plasma CAF22 and NfL levels when compared to baseline. Similar observations were not found in the placebo group. Correlation analysis revealed significant correlations of plasma CAF22 with HGS, gait speed, and cumulative SPPB scores in the metformin group. These observations were associated with reduced oxidative stress in the metformin group. CONCLUSION Altogether, the restorative effects of metformin on skeletal muscle and physical capacity involve NMJ stabilization. Our data is clinically relevant for geriatric men with functional disabilities.

Abstract
We investigated the risk factors for hip fracture in 48,533 European older adults for 8 years from 2013 onward. We identified female gender, age above 80, low handgrip strength, and depression as significant risk factors for hip fracture. Our findings may help identify high-risk populations for hip fractures in pre-clinical settings. OBJECTIVES Hip fracture is a major cause of functional disability, mortality, and health costs. However, the identification and characterization of its causative factors remain poor. METHODS We investigated demography, handgrip strength (HGS), depression, and multiple age-associated comorbidities for predicting future hip fracture in individuals aged 50 or above from 15 European countries (n = 48,533). All participants were evaluated from 2013 to 2020 using four successive waves of the Survey of Health, Aging, and Retirement in Europe (SHARE). RESULTS Altogether, 1130 participants developed hip fractures during the study period. We identified female gender, an advancing age from quinquagenarians onward, and a poor socioeconomic status as critical risk factors for future hip fracture. Having mobility difficulty, a low HGS (< 27 kg in men, < 16 kg in women) and higher scores on Euro-D depression scales were also significant risk factors for hip fracture. Summated scales of hypertension, diabetes mellitus, cancer, Alzheimer's disease, and stroke did not appear as risk factors. CONCLUSION Collectively, we report advancing age, female gender, low HGS, and depression as independent risk factors for hip fracture. Our findings are useful in identifying high-risk populations for hip fractures in pre-clinical settings before rigorous evaluation and treatment in clinics.

Kakehi S, Wakabayashi H, Isono E, Takemura R, Sato Y, Otsuka Y, Nagai T, Nishioka S, Momosaki R. Association between sarcopenia and urinary dysfunction in patients with dysphagia. Arch Gerontol Geriatr 2024; 127:105577. [PMID: 39032316 DOI: 10.1016/j.archger.2024.105577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 06/29/2024] [Accepted: 07/13/2024] [Indexed: 07/23/2024]
Abstract
INTRODUCTION The objective was to determine the relationship between sarcopenia and urinary dysfunction in patients with dysphagia. MATERIAL AND METHODS A cross-sectional study was conducted on 460 Japanese Sarcopenic Dysphagia Database participants. Urinary dysfunction was defined as either urinary incontinence or urethral catheter use. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia 2019 criteria. Univariate and multivariate analyses assessed the association between urinary dysfunction and sarcopenia, calf circumference (CC), handgrip strength (HGS), and Barthel Index (BI). Logistic regression analysis was performed for urinary dysfunction adjusted for age, sex, setting, and CCI in addition to BI and HGS or CC or sarcopenia (model 1) or FILS and BI (model 2). RESULTS The mean age was 80.8 ± 10.5 years and urinary dysfunction in 137 participants. Urinary dysfunction was not associated with sarcopenia (123 versus 281, p = 0.440) but was associated with CC (27.4 ± 4.2 versus 28.5 ± 3.9, p = 0.009), HGS (9.7 ± 7.9 versus 14.4 ± 9.3, p < 0.001), and BI (19.9 ± 0.3 versus 20.3 ± 0.2, p < 0.001). Logistic regression analysis showed urinary dysfunction was associated with HGS (OR: 0.968, CI: 0.938, 0.998) and BI (OR: 0.955, CI: 0.943, 0.966). The cutoff was 19 kg for men (sensitivity 0.786, specificity 0.56, Area Under Curve (AUC) 0.689) and 6.1 kg for women (sensitivity 0.493, specificity 0.774, AUC 0.639) in HGS and 27.5 points in BI (sensitivity 0.781, specificity 0.604, AUC 0.740). CONCLUSION Sarcopenia was not associated with urinary dysfunction. However, HGS and BI were related to urinary dysfunction.

Son J, Sung P. A Reciprocal Relationship between Formal and Informal Social Engagement and Handgrip Strength of Older Adults in South Korea. Gerontology 2024:1-15. [PMID: 39008957 DOI: 10.1159/000540344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 07/09/2024] [Indexed: 07/17/2024] Open
Abstract
INTRODUCTION The relationship between social engagement and handgrip strength has been underexplored. Further, no prior research examined a plausible reciprocal association between them. METHODS The study employed the seven waves of data (2006-2018) from the Korean Longitudinal Study of Aging (KLoSA) survey (7,927 respondents, mean age: 59 years old at wave 1 [71 years old at wave 7], women: 58%). It used ML-SEM, a cross-lagged panel model with fixed effects fitted by structural equation modeling with maximum likelihood estimation. In particular, the ML-SEM examined whether a reciprocal relationship existed between formal social engagement (number of association memberships and frequency of organizational activities)/informal social engagement (frequency of contact with familiar persons) and handgrip strength (the average of the four dynamometer measurements). RESULTS The empirical analyses identified a systematic reciprocal association between formal social engagement and handgrip strength. Specifically, formal social engagement was positively associated with handgrip strength over time (the number of association memberships standardized coefficient: 0.012*, the frequency of organizational activities standardized coefficient: 0.022***). Conversely, handgrip strength was positively related to the number of memberships (the handgrip strength standardized coefficient: 0.025*) and the frequency of organizational activities (the handgrip strength standardized coefficient: 0.042**). CONCLUSION The study thus supports the social causation proposition that formal social engagement in and through diverse associations may be positively associated with handgrip strength. It also validates the health selection argument that handgrip strength may increase the likelihood of formal social engagement.

Abstract
PURPOSE This study investigates the association between handgrip strength, walking pace, and the incidence of degenerative cervical myelopathy (DCM) using the UK Biobank dataset. METHODS We analyzed data from 364,716 UK Biobank participants without prior neurological conditions. Handgrip strength was measured with a dynamometer, and walking pace was self-reported. Cox proportional hazards models assessed hazard ratios (HRs) and 95% confidence intervals (CIs) for DCM development. RESULTS The cohort, with an average age of 56.2 years (SD, 8.1) and 47.4% male, was followed for a median of 12.6 years. During this period, 3,993 participants (1.1%) developed DCM. A significant inverse correlation was found between handgrip strength and DCM incidence (P for trend < 0.001), with decreasing HRs for DCM across quartiles of increasing grip strength: HRs were 0.70 (95% CI: 0.64-0.76), 0.62 (95% CI: 0.57-0.68), and 0.59 (95% CI: 0.54-0.66) for the second, third, and fourth quartiles, respectively. Participants with average or brisk walking paces had a lower DCM risk (HR, 0.55; 95% CI: 0.50-0.61 and HR, 0.48; 95% CI: 0.43-0.54) compared to slow walkers. The greatest risk reduction was in those with both higher handgrip strength and faster pace (HR, 0.39; 95% CI: 0.34-0.44). CONCLUSIONS Handgrip strength and walking pace are inversely associated with DCM incidence, suggesting their potential as cost-effective screening tools for identifying individuals at risk for DCM.

Abstract
INTRODUCTION Loss of muscle mass and the accumulation of visceral fat are known risk factors for the deterioration of glycemic control in type 2 diabetes mellitus. This study looked at the effects of such factors on glycemic control in Japanese patients with type 2 diabetes mellitus in the form of handgrip strength (HGS) and waist circumference (WC). MATERIALS AND METHODS In this prospective, observational study, 233 patients with type 2 diabetes mellitus and a HbA1c level of ≥7.0% were followed for around 1 year, during which time they were studied for an understanding of the association between handgrip strength, waist circumference, and glycemic control (HbA1c <7.0%). Hazard ratios (HRs) and 95% confidence intervals (CIs) for glycemic control improvement by Cox hazards models were analyzed for handgrip strength and waist circumference. RESULTS Compared with the low tertile, patients in the middle and high tertiles of handgrip strength when adjustment was carried out for waist circumference were 2.117 (1.142-3.924) and 4.670 (2.526-8.632), respectively. The HRs of patients in the middle and high tertiles of WC when adjustment was made for HGS were 0.442 (0.269-0.725) and 0.339 (0.191-0.604), respectively. Within the low, middle, and high HGS tertiles, the HRs for WC were 0.863 (0.797-0.934), 0.940 (0.899-0.982), and 1.009 (0.984-1.035), respectively, although the HRs for HGS within each WC tertile remained significant. CONCLUSIONS Handgrip strength and waist circumference demonstrated independent associations for glycemic control, but the effect of waist circumference appeared to be at least partially canceled out by increased handgrip strength. The data suggest that handgrip strength might help to mitigate the negative impact of waist circumference on glycemic control.

Association of added sugar intake and its forms and sources with handgrip strength decline among middle-aged and older adults: A prospective cohort study. Clin Nutr 2024; 43:1609-1617. [PMID: 38781671 DOI: 10.1016/j.clnu.2024.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 03/01/2024] [Accepted: 04/01/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE The consumption of added sugar has increased rapidly in recent years. Limited knowledge exists regarding the association between added sugar intake and muscle strength, although the latter is a predictor of physical disability in older adults. This study aimed to investigate the association between added sugar intake and longitudinal changes in handgrip strength among middle-aged and elderly Chinese adults. METHODS This prospective cohort study included 5298 adults aged 40 years and older (62.6% men) from the TCLSIH (Tianjin Chronic Low-grade Systemic Inflammation and Health) cohort study. Added sugar intake was obtained through a frequency questionnaire containing 100 items of food. Handgrip strength is measured annually using a handheld digital dynamometer. Multivariate linear regression models were used to examine the association between added sugars intake and the annual changes in handgrip strength and weight-adjusted handgrip strength. RESULTS In the fully adjusted model, the annual change in handgrip strength for one unit increase in total added sugar, solid added sugar, and liquid added sugar intake was -0.0353 kg, (95% confidence intervals (CI) -0.000148, -0.0000164; P = 0.01), -0.0348 kg (95% CI: -0.000227, -0.0000269; P = 0.01) and -0.0189 kg (95% CI -0.000187, 0.0000338; P = 0.17), respectively. Added sugar from bread and biscuits sources were remarkably associated with a decline in handgrip strength (β = -0.0498; 95%CI -0.00281, -0.000787) and (β = -0.0459; 95%CI 0.00158, 0.00733) (P < 0.01). CONCLUSIONS Our data suggest that the higher the intake of solid added sugars, but not liquid sugars, were associated with the declined handgrip strength in the Chinese middle-aged and elderly population. In addition, the consumption of added sugars from bread and biscuits sources was also associated with a decline in grip strength.

Abstract
OBJECTIVES Evaluate associations between triceps braqui muscle ultrasound measures (TB US) and handgrip strength (HGS), and the sensibility of TB US for low HGS in non-dialysis-dependent chronic kidney disease (nd-CKD) patients. PARTICIPANTS AND METHODS This pilot, cross-sectional, and exploratory study evaluated TB cross-sectional images from A-mode US and processed by FIJI-Image J to obtain muscle thickness (MT), echogenicity (EI), cross-sectional area (CSA), pennation angle (PA), and fascicle length (Lf) associating them with absolute HGS by simple and, multiple linear regression. The HGS was normalized to body mass index (BMI) and separated into low HGS (HGS/BMI≤10p according to sex and age) and adequate HGS (HGS/BMI>10p) groups. The body composition was from multifrequency bioimpedance. ROC analysis verified the TB US diagnostic accuracy to low HGS. RESULTS Were included 42 (21M/21F) adults with 65.5 (60-70) y median age, 47.22% in 3b CKD stage. The low HGS group (45.23%) showed a higher fat mass (FM), TB muscle medium head's PA, and EI than adequate HGS (p<0.05). In crude model, a pixels increase in EI was associated with a 0.452kgf HGS reduction (p=0.019); adjusted for sex, age, and FM, a one-unit increase in EI was associated with a 0.510kgf HGS reduction (p=0.011). The EI also showed moderate diagnostic accuracy (AUC=0.730; CI 95%=0.589; 0.919) to low HGS and a sensitivity of 86.9% (cutoff≥13.52 pixels). CONCLUSION In nd-CKD patients, of all measurements from US, the EI was the most associated with HGS, and the only one sensitive to low HGS diagnosis.

Abstract
Although vitamin C is one of the most important antioxidants, its effect on muscle quality is not fully understood. Therefore, we hypothesized that low dietary vitamin C intake is associated with low muscle strength. To test the hypothesis, a single 24-h dietary recall and handgrip strength test of 10,883 younger adults 19-64 y and 3,961 older adults ≥65 y from the seventh Korea National Health and Examination Survey (KNHANES VII 2016-2018) was analyzed by multivariable linear and logistic regression models, and low muscle strength was defined as handgrip strength <28 kg for men and <18 kg for women. Approximately 15.5% of Korean adults met the recommended intake of dietary vitamin C, and those with higher dietary vitamin C intake had higher total energy and protein intake. After adjusting for confounding variables, including age, body mass index, total energy intake, household income, alcohol consumption, smoking, resistance exercise, medical condition, and dietary intake of protein, vitamin E, and β-carotene, dietary vitamin C was correlated with maximal handgrip strength in younger women 19-64 y (β = 0.002; SE = 0.001; P-value = .026) and older women ≥65 y (β = 0.005; SE = 0.002; P-value = .013). Among older women ≥65 y, those in the lowest quartile of dietary vitamin C intake had a higher risk of low muscle strength compared to those in the highest quartile after adjustment of confounding factors (odds ratio, 2.16; 95% confidence interval, 1.49-3.15). These results imply that adequate dietary vitamin C intake may reduce the risk of sarcopenia in older Korean women.

Abstract
BACKGROUND Age-associated muscle decline, termed sarcopenia, is a common systemic effect of chronic obstructive pulmonary disease (COPD). Circulating Neurofilament light chain (NfL) levels reflect neuronal degradation and may be relevant to sarcopenia phenotype. However, such an association in COPD patients remains elusive. METHODS We investigated male, 60-76 years old controls (n = 50) and COPD patients (n = 139) for plasma NfL levels in relation to sarcopenia and physical capacity markers. We measured handgrip strength (HGS), body composition, and short physical performance battery (SPPB) to evaluate sarcopenia and physical capacity. RESULTS COPD patients had higher plasma NfL and lower HGS and SPPB performance than controls. Plasma NfL levels demonstrated negative associations with HGS and gait speed in COPD patients (all p < 0.05). Further, NfL levels were negatively associated with total SPPB scores in controls and patients with advanced COPD (p < 0.05). Plasma NfL also demonstrated an acceptable accuracy in diagnosing sarcopenia in controls (AUC = 0.757, p < 0.05) and COPD (AUC = 0.806, p < 0.05) patients. CONCLUSION Collectively, plasma NfL may be helpful in evaluating sarcopenia phenotype and physical capacity in geriatric patients with COPD.

Abstract
BACKGROUND Muscular strength and muscle mass are considered key factors for healthy ageing. Modification of body composition and redistribution of adipose tissue has been described in advanced age. Muscle strength has an important predictive role for health outcomes. However, little is known regarding the relationship between muscle strength and epicardial fat. METHODS AND MATERIALS In a cohort of healthy adults following physical capacity evaluations, anthropometric measurements, handgrip strength (HGS), echocardiography and bioimpedance analysis (BIA) were performed. Kruskal-Wallis test, Spearman's correlation and regression analysis adjusted for confounders were applied. RESULTS A total population of 226 adults, age range 18-83 years, were included. Epicardial fat thickness resulted significantly associated with age p < 0.001, HGS (p < 0.001). Regression analysis adjusted for confounders revealed an independent relationship between handgrip strength and epicardial fat thickness: regression coefficient: -1.34; R2 = 0.27 and p = 0.044. CONCLUSIONS The relationship between epicardial fat and muscle strength is inverse and independent. Implementation of HGS measurement may be useful for the identification of subjects with excessive epicardial fat and cardiovascular risk. Measurement of epicardial fat could be helpful in the early detection of physical decline associated to ageing.

Abstract
Soft drink consumption has become a highly controversial public health issue. Given the pattern of consumption in China, sugar-sweetened beverage is the main type of soft drink consumed. Due to containing high levels of fructose, a soft drink may have a deleterious effect on handgrip strength (HGS) due to oxidative stress, inflammation and insulin resistance. However, few studies show an association between soft drink consumption and HGS in adults. We aimed to investigate the association between soft drink consumption and longitudinal changes in HGS among a Chinese adult population. A longitudinal population-based cohort study (5-year follow-up, median: 3·66 years) was conducted in Tianjin, China. A total of 11 125 participants (56·7 % men) were enrolled. HGS was measured using a handheld digital dynamometer. Soft drink consumption (mainly sugar-containing carbonated beverages) was measured at baseline using a validated FFQ. ANCOVA was used to evaluate the association between soft drink consumption and annual change in HGS or weight-adjusted HGS. After adjusting for multiple confounding factors, the least square means (95 % CI) of annual change in HGS across soft drink consumption frequencies were -0·70 (-2·49, 1·09) for rarely drinks, -0·82 (-2·62, 0·97) for < 1 cup/week and -0·86 (-2·66, 0·93) for ≥ 1 cup/week (Pfor trend < 0·05). Likewise, a similar association was observed between soft drink consumption and annual change in weight-adjusted HGS. The results indicate that higher soft drink consumption was associated with faster HGS decline in Chinese adults.

Abstract
The purpose of this study was to compare single- and multi-frequency bioimpedance (BIA) devices against dual-energy X-ray absorptiometry (DXA) for appendicular lean mass (ALM) and muscle quality index (MQI) metrics in Hispanic adults. One hundred thirty-one Hispanic adults (18-55 years) participated in this study. ALM was measured with single-frequency bioimpedance analysis (SFBIA), multi-frequency bioimpedance analysis (MFBIA) and DXA. ALMTOTAL (left arm + right arm + left leg + right leg) and ALMARMS (left arm + right arm) were computed for all three devices. Handgrip strength (HGS) was measured using a dynamometer. The average HGS was used for all MQI models (highest left hand + highest right hand)/2. MQIARMS was defined as the ratio between HGS and ALMARMS. MQITOTAL was established as the ratio between HGS and ALMTOTAL. SFBIA and MFBIA had strong correlations with DXA for all ALM and MQI metrics (Lin's concordance correlation coefficient values ranged from 0·86 (MQIMFBIA-ARMS) to 0·97 (Arms LMSFBIA); all P < 0·001). Equivalence testing varied between methods (e.g. SFBIA v. DXA) when examining the different metrics (i.e. ALMTOTAL, ALMARMS, MQITOTAL and MQIARMS). MQIARMS was the only metric that did not differ from the line of identity and had no proportional bias when comparing all the devices against each other. The current study findings demonstrate good overall agreement between SFBIA, MFBIA and DXA for ALMTOTAL and ALMARMS in a Hispanic population. However, SFBIA and MFBIA have better agreement with DXA when used to compute MQIARMS than MQITOTAL.

Abstract
PURPOSE Current handgrip strength (HGS) protocols employ a variety of criteria, affecting the assessment of asymmetric HGS. The impact of these different criteria on fall prediction is understudied. This study was devised to compare the relative performance of average and maximum HGS asymmetry criteria as tools to predict fall incidence among middle-aged or older adults in China. METHODS 9627 Chinese adults 50 + years of age who were participants in the China Health and Retirement Longitudinal Study (2013-2015 waves) were evaluated. The measurement of HGS was achieved based on either the maximum recorded value (HGSmax) or the average (HGSave), and these values were employed for the calculation of HGS asymmetry. Fall incidence over a 2-year period was evaluated based on self-reported data. Logistic regression analyses were utilized to determine the predictive performance of HGSmax asymmetry or HGSave asymmetry when gaging 2-year fall risk. RESULTS Significant differences in overall rates of HGS asymmetry and the rates of subdivisions thereof were observed when comparing the HGSmax and HGSave criteria, with moderate consistency (kappa = 0.599, p < 0.001). Over the 2-year follow-up period, 1743 fall incidents were recorded. Adjusted logistic regression models indicated that only HGSmax asymmetry > 30.0% was significantly related to fall risk (p = 0.034, odds ratio = 1.36, 95% confidence interval: 1.02-1.81). CONCLUSION These findings highlight the importance of HGS criteria in detecting HGS asymmetry, and suggest that HGSmax is a more robust criterion for predicting fall risk among Chinese adults 50 + years of age.

Abstract
BACKGROUND Population-based evidence on the relationship between dynapenic abdominal obesity and depressive symptoms is rare. We aimed to prospectively investigate the relationship between dynapenic abdominal obesity and depressive symptoms among middle-aged and older Chinese adults. METHODS A total of 9322 participants free of depressive symptoms in the China Health and Retirement Longitudinal Study were included. The participants were divided into four groups: non-dynapenic/non-abdominal obesity (ND/NAO), non-dynapenic/abdominal obesity (ND/AO), dynapenic/non-abdominal obesity (D/NAO) and dynapenic/abdominal obesity (D/AO) according to the sex-specific grip strength (<28 kg for men and <18 kg for women) and waist circumference (≥85 cm for men and ≥80 cm for women) that in line with the Chinese criteria. Depressive symptoms was defined as a score of ≥12 for the 10-item Center for Epidemiological Studies Depression Scale. Logistic regression model was used to explore the association between dynapenic abdominal obesity and depressive symptoms. RESULTS After an approximately 3-year of follow-up, 1810 participants (19.4 %) developed depressive symptoms. The multivariable-adjusted odds ratio for the D/AO versus ND/NAO was 1.61 (95 % CI: 1.31-1.98) for depressive symptoms. In addition, this relationship was more profound in participants aged<60 years (OR = 2.27, 95 % CI: 1.60-3.22) than participants aged ≥60 (OR = 1.36, 95 % CI: 1.05-1.77; P-interaction = 0.04). However, dynapenic obesity (defined by body mass index) was not linked to depressive symptoms. LIMITATIONS Causal link and residual confounding were not addressed because of the observational study design. CONCLUSIONS Dynapenic abdominal obesity was associated with an increased risk of depressive symptoms, especially among those aged<60 years.
