Abstract
BACKGROUND Muscular function, such as handgrip strength, has been suggested as an associated factor for cognitive impairment. This study investigated the association between temporal change in handgrip strength and cognitive function using longitudinal, nationwide data from Korean older adults. METHODS Our study used data from the Korean Longitudinal Study of Aging (KLoSA). The analysis covered 6696 participants who had taken the handgrip strength test and Mini-Mental State Examination (MMSE) from 2006 to 2018. We adopted general estimating equations to assess the temporal effect of handgrip strength change on cognitive function. RESULTS After adjusting for covariates, we observed an association between handgrip strength and low MMSE scores (β = - 0.3142 in men, β = - 0.2685 in women). Handgrip strength as a continuous variable was positively correlated with MMSE scores after adjustment (β = 0.0293 in men, β = 0.0347 in women). The group with decreased handgrip strength over time also showed greater odds for mild cognitive impairment (OR = 1.23, 95%CI = 1.05-1.27 in men, OR = 1.15, 95%CI = 1.05-1.27 in women) and dementia (OR = 1.393, 95%CI = 1.18-1.65 in men, OR = 1.19, 95%CI = 1.08-1.32 in women). CONCLUSIONS This study identified the relationship between handgrip strength change and cognitive function among South Korean adults. According to our large, longitudinal sample, decreasing handgrip strength was associated with decline in cognitive function.

Low fat mass index outperforms handgrip weakness and GLIM-defined malnutrition in predicting cancer survival: Derivation of cutoff values and joint analysis in an observational cohort. Clin Nutr 2021; 41:153-164. [PMID: 34883304 DOI: 10.1016/j.clnu.2021.11.026] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 11/17/2021] [Accepted: 11/22/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND & AIMS The optimal thresholds to define a survival-related low fat mass index (FMI) in Asian oncology populations remains largely unknown. This study sought to derive the sex-specific FMI cutoffs and analyze the independent and joint associations of a low FMI, handgrip weakness, and the Global Leadership Initiative on Malnutrition (GLIM)-defined malnutrition with cancer survival. METHODS We performed a multicenter cohort study including 2376 patients with cancer. The FMI was measured by bioelectrical impedance analysis and the best thresholds were determined using an optimal stratification (OS) method. Low handgrip strength (HGS) and malnutrition were defined based on the Asian Working Group for Sarcopenia 2019 framework and the GLIM, respectively. The associations of a low FMI, handgrip weakness and malnutrition with survival were estimated independently and jointly by calculating multivariable-adjusted hazard ratios (HRs). RESULTS The study enrolled 1303 women and 1073 men with a mean age of 57.7 years and a median follow-up of 1267 days. The OS-defined FMI cutoffs were <5 kg/m2 in women and <7.7 kg/m2 in men. A low FMI, low HGS and malnutrition were identified in 1188 (50%), 1106 (46.5%) and 910 (38.3%) patients, respectively. A low FMI was adversely associated with the nutritional status, physical performance, quality of life and hospitalization costs. A low FMI (HR = 1.50, 95%CI = 1.16 to 1.92) and malnutrition (HR = 1.31, 95%CI = 1.08 to 1.59) were independently associated with mortality. Overall, the FMI plus GLIM-defined malnutrition showed the maximal joint prognostic impact, and patients with a combined low FMI and malnutrition had the worst survival (HR = 1.93, 95%CI = 1.48 to 2.52). CONCLUSIONS Low FMI-indicated fat depletion outperforms and strengthens the prognostic value of handgrip weakness and GLIM-defined malnutrition for cancer survival. These findings indicate the importance of including fat mass assessment during routine cancer care to help guide strategies to optimize survival outcomes.

Abstract
OBJECTIVE To evaluate the associations of sarcopenia, handgrip strength and calf circumference with cognitive impairment among Chinese older adults. METHODS Totally 2,525 older adults were recruited from the Healthy Aging and Biomarkers Cohort Study. Cognitive impairment was assessed by the Chinese Mini-Mental State Examination. Handgrip strength was calculated from the means of the right and left hand values. Calf circumference was measured at the site of maximum circumference of the non-dominant leg. The formula developed by Ishii was used to define sarcopenia. Multiple logistic regression was performed to evaluate the associations of sarcopenia, handgrip strength, and calf circumference with cognitive impairment. RESULTS The prevalence of cognitive impairment was 34.36%. The adjusted odds ratio ( OR) for cognitive impairment in individuals with sarcopenia was 2.55 [95% confidence interval (95% CI): 1.86-3.50]. Compared with individuals in the first quartile (Q 1) of calf circumference, the adjusted ORs in the second, third, and fourth quartiles (Q 2, Q 3, and Q 4) were 0.75 (95% CI: 0.58-0.96), 0.59 (95% CI: 0.44-0.79), and 0.62 (95% CI: 0.45-0.8), respectively. Compared with individuals in Q 1 of handgrip strength, the adjusted ORs for Q 2, Q 3, and Q 4 were 0.49 (95% CI: 0.38-0.62), 0.31 (95% CI: 0.23-0.41), and 0.30 (95% CI: 0.21-0.44), respectively. CONCLUSION Sarcopenia, identified by low handgrip strength and low calf circumference, was positively associated with cognitive impairment.

Abstract
OBJECTIVE Current evidence on the relationship between decreased handgrip strength and depression risk is controversial, and there is limited study focus on the potential bidirectional associations between them. We aim to explore their bidirectional relationships. METHODS This study used panel data from the Health and Retirement Study involving 17,713 aging Americans (≥50 years old) who participated in at least 2 waves. Smedley spring-type hand-held dynamometer was used to assess the handgrip strength. Depression was evaluated by the 8-item Center for Epidemiologic Studies-Depression (CESD) scale. Time-lagged general estimating equations (GEE) were used to assess the bidirectional association between handgrip strength and the depression risk. RESULTS In the fully adjusted model, every 5 kg decreased handgrip strength was associated with a 6% (95%CI: 3%-9%) increased risk of depression. Compared with non-weakness participants, those with weakness had a higher depression risk (OR = 1.22, 95%CI: 1.09-1.36). Conversely, depression might associate with a 0.33 kg (95% CI: 0.09-0.56) decrease in handgrip strength and increased the risk of weakness by 18% (95% CI: 6%-33%). In addition, the results remained stable in the stratified analyses by gender and sex. Interestingly, the above-mentioned associations were also observed in overweight and obese participants. CONCLUSIONS The present study found bidirectional associations between handgrip strength and depression risk. Our results indicated early interventions for depression and handgrip strength might achieve reciprocal benefits over time.

Abstract
Background The first objective of this study was to determine the relationship between muscle strength or physical performance and mortality, and the second objective was to show the relationship of Geriatric Nutritional Risk Index (GNRI) to muscle strength and physical performance decline. Methods We examined handgrip, the 5-times chair stand test, and GNRI in 635 maintenance hemodialysis patients and followed up for 72 months. Predictors for all-cause death were examined using Kaplan-Meier analysis and Cox proportional analysis. The relationship between possible sarcopenia and nutritional disorder (GNRI) was constructed receiver operating characteristic (ROC) curve. We used the Youden index to determine the optimal cutoff points for GNRI. Results The multivariate Cox proportional hazard analysis revealed that the GNRI did not show any significance, although handgrip (HR 3.61, 95% CI 1.70–7.68, p < 0.001) and the 5-times chair stand test (HR 1.71 95% CI 1.01–2.90, p = 0.045) were significant predictors for mortality. On the evaluation of possible sarcopenia by handgrip strength, the area under curve (AUC) on ROC curve analysis were 0.68 (95% CI 0.64–0.72), and 5-chair stand, the AUC on ROC were 0.55 (95% CI 0.51–0.60). The cut-off value for the GNRI discriminating those at possible sarcopenia by handgrip strength based on the Youden index was 91.5. Conclusions Our study suggests that the handgrip strength test of the AWGS 2019 sarcopenia consensus was a simple and useful tool to predict mortality in chronic hemodialysis patients. Furthermore, GNRI assessment can be a useful tool for screening before assessing possible sarcopenia when it is difficult to perform SARC-F to all patients.

Abstract
Background The operational definition of sarcopenia has been updated (EWGSOP2) and apply different cut-off points compared to previous criteria (EWGSOP1). Therefore, we aim to compare the sarcopenia prevalence and the association with mortality and dependence in activities of daily living using the 2010 (EWGSOP1 and 2019 (EWGSOP2 operational definition, applying cut-offs at two levels using T-scores. Methods Two birth cohorts, 70 and 85-years-old (n = 884 and n = 157, respectively), were assessed cross-sectionally (57% women). Low grip strength, low muscle mass and slow gait speed were defined below − 2.0 and − 2.5 SD from a young reference population (T-score). Muscle mass was defined as appendicular lean soft tissue index by DXA. The EWGSOP1 and EWGSOP2 were applied and compared with McNemar tests and Cohen’s kappa. All-cause mortality was analyzed with the Cox-proportional hazard model. Results Sarcopenia prevalence was 1.4–7.8% in 70-year-olds and 42–62% in 85 years-old’s, depending on diagnostic criteria. Overall, the prevalence of sarcopenia was 0.9–1.0 percentage points lower using the EWGSOP2 compared to EWGSOP1 when applying uniform T-score cut-offs (P < 0.005). The prevalence was doubled (15.0 vs. 7.5%) using the − 2.0 vs. -2.5 T-scores with EWGSOP2 in the whole sample. The increase in prevalence when changing the cut-offs was 5.7% (P < 0.001) in the 70-year-olds and 17.8% (P < 0.001) in the 85-year-olds (EWGSP2). Sarcopenia with cut-offs at − 2.5 T-score was associated with increased mortality (hazard ratio 2.4–2.8, P < 0.05) but not at T-score − 2.0. Conclusions The prevalence of sarcopenia was higher in 85-year-olds compared to 70-year-olds. Overall, the differences between the EWGSOP1 and EWGSOP2 classifications are small. Meaningful differences between EWGSOP1 and 2 in the 85-year-olds could not be ruled out. Prevalence was more dependent on cut-offs than on the operational definition.

Abstract
OBJECTIVES To examine factors relating to both sexual inactivity and sexual dysfunction in midlife Singaporean women. STUDY DESIGN Sociodemographic, medical/lifestyle factors, physical activity, BMI, handgrip strength (HGS) and physical performance data collected from healthy Chinese, Indian, and Malay women, aged 45-69 years, attending gynaecology clinics. MAIN OUTCOME MEASURES Sexual inactivity and sexual dysfunction (defined as total score ≤ 26.55) assessed using the Female Sexual Function Index (FSFI). RESULTS 1048 women completed the FSFI. Mean (±SD) age was 56.2 (±6.2). Sexual inactivity was reported by 43.2% and was positively associated with older age [55-64 years (aOR 2.0, 95% CI 1.3-3.0) and ≥65 years (aOR 2.5, 95% CI 1.2-5.1)], younger menarche (aOR 1.8, 95% CI 1.3-2.5), lowest education (aOR 2.1, 95% CI 1.2-3.6), lowest income (aOR 1.8, 95% CI 1.1-2.8), unmarried (aOR 4.0, 95% CI 2.6-6.4), nulliparity (aOR 1.9, 95% CI 1.1-3.4), and BMI <18.5 kg/m2 (aOR 2.7, 95% CI 1.3-5.6). Among the sexually active, sexual dysfunction was identified in 70.3%. Sexual dysfunction was positively associated with menopause ≥10 years (aOR 2.4, 95% CI 1.1-5.0), nulliparity (aOR 3.0, 95% CI 1.1-9.8), moderate/severe vaginal dryness (aOR 13.8, 95% CI 4.8-38.7) and HGS <18 kg (aOR 1.9, 95% CI 1.1-3.2) and negatively associated with use of menopausal hormone therapy (aOR 0.3, 95% CI 0.1-0.6). CONCLUSION This, the largest Singaporean sexual function study, is the first to include physical performance in a healthy population. Most were sexually active but reported dysfunction. Novel associations included underweight BMI with sexual inactivity and weaker HGS and Malay ethnicity with greater and less sexual dysfunction, respectively.

Abstract
OBJECTIVE This study aimed to evaluate the nutritional status and handgrip strength (HS) in patients with Parkinson's disease (PD). METHODOLOGY This is a cross-sectional study with outpatients in two treatment centers in the state of Pernambuco. Sociodemographic data, body mass index (BMI), waist circumference (WC), and calf circumference (CC) were collected. Body fat (BF) was assessed using electrical bioimpedance. Dynapenia was assessed using HS and dynapenic obesity was defined as very high WC associated with low HS. The Hoehn-Yahr scale was used for the staging of PD and the disease's severity was assessed by the Unified Parkinson's Disease Rating Scale (UPDRS). RESULTS The results showed that 77.2% were elderly, which were at II and III stages of UPDRS scale. Overweight and obesity were present in 44.3% and 27.8%. Dynapenia was found in 50.6%. A negative correlation was observed between HS with age, UPDRS II and III, and BF percentage. Dynapenic obesity in men was lower 37.5% compared to women 63.6%. CONCLUSION It is relevant to identify the functional capacity such as dynapenia and also the nutritional status in people living with neurodegenerative diseases of early onset, such as PD, so it is possible to develop strategies in prevention and treatment that can improve these conditions, considering its negative impact in PD.

Abstract
PURPOSE Geriatric nutritional risk index (GNRI) is one of the new tools to determine nutritional status in the elderly. This study assessed the association between GNRI and muscular strength through handgrip strength (HGS) in patients undergoing hemodialysis. METHODS This cross-sectional analytical study assessed 110 hemodialysis patients at Guilan, North of Iran, (mean age of 70.3 ± 6.93), 57 men and 53 women through simple random sampling. Demographic characteristics, GNRI, and HGS of patients were determined. Data were analyzed using descriptive and inferential statistics, including independent t test, AVOVA, Pearson correlation, and linear multiple regression tests. RESULTS The mean values of the GNRI and HGS were 93.90 ± 11.06 and 14.82 ± 3.72, respectively. Finally, it was identified that there is a direct and significant association between GNRI and HGS (p = 0.001, r = 0.734). Linear multiple regression showed that GNRI is an independent predictor of HGS (Adj.R2 = 0.67, βGNRI = 8.13). CONCLUSION GNRI can be used as a predictor of muscular strength in hemodialysis patients.

Abstract
The present study aimed to investigate the effects of traditional resistance training compared to elastic tubes training on bioimpedance vector patterns, body composition, and strength in older women. Thirty-eight older women (age 68.7 ± 6.9 years, body mass index 28.8 ± 7.2 kg/m2) were randomly assigned to perform traditional resistance or elastic tubes training three times per week for 12 weeks. Body composition was assessed by dual energy X-ray absorptiometry and bioelectrical impedance vector analysis. In addition, handgrip strength was measured using a dynamometer. Only the participants who followed the 12-week traditional resistance training program significantly (p < 0.05) decreased fat mass (ES: -0.69) and extracellular water (ES: -1.06), and increased total body water (ES: 0.49), intracellular water (ES: 1.11), body cell mass (ES: 0.82), muscle mass (ES: 0.94), and phase angle (ES: 0.99), while no change occurred in the elastic tubes training group. Furthermore, a vector leftward displacement (ES: 1.11) into the resistance-reactance graph was found only after the traditional resistance training program. The handgrip strength increased for both traditional and elastic tubes training groups (ES: 0.64, ES: 0.71, respectively). Traditional resistance training improved body composition and strength in the older women group, while training using elastic tubes was effective only for the latter. The present outcomes encourage the use of systematic resistance training to counteract the effects of aging in older women.

Abstract
Previous reports of an association between handgrip strength (HGS) and the risk of hypertension have utilized cross-sectional designs. We aimed to assess the prospective association between HGS and hypertension risk in a general population. Handgrip strength was assessed at baseline in 463 Finnish men and women aged 61-73 years. Handgrip strength was normalized (HGS/body weight2/3). After 16 years median follow-up, 110 hypertension cases occurred. Comparing the extreme tertiles of normalized HGS, the multivariable adjusted hazard ratio (95% CI) for hypertension was 0.63 (0.38-1.04). Previous evidence of associations may have been driven by study design limitations such as lack of temporality.

Abstract
BACKGROUND Metabolic syndrome (MetS) may adversely influence muscle strength. However, the relationship remains poorly understood in China, despite its large older population and the high prevalence of MetS. OBJECTIVES We aimed to investigate the association between MetS and muscle weakness among older Chinese. METHODS We included 2,418 older adults who completed the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study (CHARLS) and had normal handgrip strength at baseline. Data were analyzed using descriptive statistics and logistic regressions. RESULTS Baseline MetS was associated with increased risks for incident muscle weakness (OR = 1.35, 95% CI: 1.08-1.67). Among all the MetS components, baseline central obesity component was predictive of muscle weakness. The association between MetS and declined muscle strength existed in men but not women. CONCLUSION There was an increased risk of muscle strength decline associated with MetS, which was more prominent in men.

Abstract
To investigate the relationship between handgrip strength (HGs) features, evaluated with an innovative cylindrical-shaped grip device, and demographic, anthropometric and clinical variables, in patients with rheumatoid arthritis (RA). Consecutive RA patients were prospectively enrolled for this cross-sectional study. For each patient were collected demographic, anthropometric, clinical data related to disease activity. HGs was assessed in terms of area under the force–time curve (AUC-FeT), peak grip force and time to reach the curve plateau. The correlations between the variables were studied with the Spearman’s rho correlation coefficient. The receiver operating characteristic (ROC) curve analysis was used to test the discriminant accuracy of HGs features in identifying patients in moderate/high disease activity. A multivariate analysis was performed to estimate the contribution of covariates on the AUC-FeT. A significant correlation was found among AUC-FeT, age, Simplified Disease Activity Index (SDAI), Ultrasound-Clinical Arthritis Activity (US-CLARA) (all at p < 0.0001), and body mass index (BMI) (p = 0.0001). Any correlation was found between HGs and radiographic damage. The discriminatory power of AUC-FeT was good [area under-ROC curve = 0.810 (95% CI 0.746–0.864)]. Variables significantly associated with AUC-FeT in multivariate analysis were age (p = 0.0006), BMI (p = 0.012), gender (p = 0.004), SDAI (p = 0.047) and US-CLARA (p = 0.023). HGs is negatively influenced by demographic (gender and age), anthropometric (BMI), and disease activity variables (SDAI and US-CLARA). These findings highlight the role of HGs in RA patients' functional impairment and disability.

Lower muscular strength is associated with smaller left and right chambers and lower cardiac mass in the general population - The Sedentary's Heart. Prog Cardiovasc Dis 2021; 68:36-51. [PMID: 34562438 DOI: 10.1016/j.pcad.2021.09.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 09/13/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND The cardiac muscle has the ability to adapt to different loading conditions. We analyzed the associations of the age-related decreasing handgrip strength (HGS), a marker of muscular fitness, on cardiac structure and function in a community-based sample. METHODS We performed cross-sectional analyses of 4646 subjects (2554 women; 55.0%) aged 20 to 93 years from two independent cohorts of the Study of Health in Pomerania (SHIP-2 and SHIP-TREND-0). We analyzed the associations of HGS with structural and functional left and right ventricular (LV and RV) and left atrial (LA) parameters as determined by echocardiography and magnetic resonance imaging (MRI) as well with log-transformed NT-proBNP values using multivariable-adjusted linear regression models. RESULTS MRI data showed that a 1 kg lower HGS was associated with a 0.40 mL (95% confidence interval: 0.26 to 0.54; p < 0.001) lower LV end-diastolic volume, a 0.011 mm (0.005 to 0.018; p = 0.001) lower LV wall-thickness, a 0.59 g (0.43 to 0.75; p < 0.001) lower LV mass, a 0.58 mL/beat (0.43 to 0.74; p < 0.001) lower LV stroke volume, a 0.03 L/min (0.02 to 0.04; p < 0.001) lower LV cardiac output, a 0.48 mL (0.27 to 0.68; p < 0.001) lower LA end-diastolic volume, and a 1.02 mL (0.71 to 1.32) lower RV end-diastolic volume. Similar findings were observed for echocardiographic parameters. Moreover, lower HGS was associated with higher echocardiographic LV diastolic stiffness and NT-proBNP levels. CONCLUSIONS In this large population-based sample, lower muscular fitness as assessed by HGS was associated with lower LV wall thickness and mass as well as with smaller chamber size, stroke volume and cardiac output of the LV, LA and RV. Moreover, HGS was inversely related to LV diastolic stiffness and NT-proBNP values. These outcomes might demonstrate the effects of an aging-related decrease in physical activity and lower muscular fitness on the heart - "the sedentary's heart".

BMC Geriatr 2021; 21:513. [PMID: 34563124 PMCID: PMC8466740 DOI: 10.1186/s12877-021-02470-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Accepted: 09/10/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND It is unclear whether visual and hearing acuity are independently or synergistically associated with muscle strength. We aimed to examine the associations of visual and self-reported hearing acuity with low handgrip strength and the additive interaction between visual and hearing acuity on low handgrip strength in people over 60 years. METHOD Data of 3,075 individuals aged over 60 years from the 2017 and 2018 Korea National Health and Nutrition Examination Survey were used for this cross-sectional study. Low handgrip strength was defined based on the 20th percentile of the study population (< 30.4 kg for male and < 17.7 kg for female). Visual and self-reported hearing acuity were each divided into three categories: good, moderate, and impaired. Multiple logistic regression and relative excess risk due to interaction (RERI) were performed. RESULTS Of the 3,075 participants, 993 (32.3 %) demonstrated low handgrip strength. Low handgrip strength was more prevalent in participants with moderate (adjusted odds ratio [AOR] = 1.54, 95 % confidence interval [CI] = 1.12-2.12) and impaired visual acuity (AOR = 2.00, 95 % CI = 1.34-2.96). Both moderate and impaired self-reported hearing acuity were significantly associated with low handgrip strength (moderate: AOR = 1.25, 95 % CI = 1.01-1.55; impaired: AOR = 1.66, 95 % CI = 1.15-2.38). The more severe the sensory function decline, the higher the association with muscle weakness. Moreover, combined sensory impairments were associated with deteriorating low handgrip strength (AOR = 8.38), with significantly strong additive interactions (RERI = 2.61, 95 % CI = 2.52-2.70). CONCLUSIONS Awareness is needed regarding the risk of reduced muscle strength in individuals with moderate and impaired sensory function. Older people with sensory function decline in clinical settings may benefit from programs such as exercise prescription to prevent muscle weakness.

Abstract
BACKGROUND Plasma amyloid-beta (Aβ), neurofilament light chain (NfL), and progranulin (PGRN) have been related to multiple neurodegenerative conditions that might affect physical performance. The aim of this study was to explore the relationship between these plasma neurodegenerative markers and physical performance among community-dwelling older adults. METHODS Five hundred and seven older adults (aged 76 ± 5 years) previously recruited in the Multidomain Alzheimer's Preventive Trial, and had received blood and physical performance tests, were included in this study. Plasma Aβ (Aβ 42/Aβ 40 ratio), NfL, and PGRN levels were measured. Physical performance was assessed by handgrip strength and the Short Physical Performance Battery (combining gait speed, chair stands, and balance tests). Physical performance measured at the same time point and after the blood tests were used. Mixed-effect linear models were performed with age, sex, allocation to Multidomain Alzheimer's Preventive Trial group, body mass index, and Mini-Mental State Examination score as covariates. RESULTS The mean values of Aβ 42/Aβ 40 ratio, NfL, and PGRN were 0.11, 84.06 pg/mL, and 45.43 ng/mL, respectively. At the cross-sectional level, higher plasma NfL was associated with a lower Short Physical Performance Battery score (β = -0.004, 95% CI [-0.007, -0.001]). At the longitudinal level, higher PGRN levels were associated with decreasing handgrip strength over time (β = -0.02, 95% CI [-0.04, -0.007]). All the other associations were statistically nonsignificant. CONCLUSION Our findings suggest the possibility of using plasma NfL and PGRN as markers of physical performance in older adults.

Abstract
BACKGROUND & AIMS The use of handgrip strength (HGS) as a proxy of nutritional status in sick children has not been studied. This study created HGS centile charts in healthy children and explored the utility of HGS z-scores as markers of body composition and screening of malnutrition risk in sick children. METHODS Data from 535 healthy children aged 5-16 years were used for the development of HGS centiles adjusted either for age or height. In 595 sick children, relationships between HGS z-scores with body composition, malnutrition risk (Paediatric Yorkhill Malnutrition Score-PYMS), length of hospital stay (LOS) and biomarkers of disease severity were explored. The use of HGS z-score to identify sick children in need of further dietetic assessment was investigated. RESULTS Children scoring at high malnutrition risk with PYMS had lower HGS z-scores for age (by 0.51 SD, p < 0.001) and height (by 0.46 SD, p = 0.001) than those who scored low. A HGS z-score at cut-offs of -0.81 SD and -1.2 SD for age and height, respectively, was predictive of need for dietetic intervention in sick children with sensitivity of 79% and 70% and specificity of 56% and 69%, respectively. HGS z-scores were predictive of fat free mass (FFM) in sick and healthy (all p < 0.001) children, while fat mass was not. HGS z-scores were inversely related with plasma CRP (rho, age: -0.21; height: -0.23, both p = 0.001). HGS was not predictive of LOS. CONCLUSION HGS is predictive of FFM, could compliment assessment of malnutrition risk, and may help identify children for further dietetic intervention on admission to hospital.

Abstract
The present study aimed to determine whether certain diets lower the risk of low muscle strength in patients with autosomal dominant polycystic kidney disease (ADPKD). In this cross-sectional study, outpatient ADPKD patients were enrolled from a tertiary care hospital. Muscle strength was assessed on the basis of handgrip strength (HGS), and dietary pattern indices were calculated using dietary intake data. Among the 68 participants included in this study, 19 (27.9%) had low HGS. Cystatin C concentrations were significantly higher in all participants, and in women in the low compared to the normal HGS group in the unadjusted analyses (P = 0.004). Among analyzed dietary pattern indices, the Dietary Approaches to Stop Hypertension (DASH) score was lower, for all participants and men, in the low compared to the normal HGS group (P < 0.05). Especially, the component score for whole grains of the DASH score was significantly lower in men in the low compared to the normal HGS group in unadjusted analyses. The DASH score was positively correlated with HGS in men (r = 0.387, P = 0.046). In addition, logistic regression analysis showed that the DASH score was negatively associated with low HGS, for all participants (odds ratio = 0.851, P = 0.049) and men (odds ratio = 0.716, P = 0.043), after adjusting for age, sex, and body weight. These findings suggest that the DASH dietary pattern may promote the preservation of muscle strength in ADPKD patients. The DASH diet can be considered as a nutritional strategy to maintain muscle strength and prevent sarcopenia in ADPKD patients.

Abstract
Objective Previous studies have shown that relative handgrip strength, handgrip measure divided by body mass index (BMI), affects the future onset of diabetes and prediabetes. However, fat free mass (FFM) has been suggested to adjust for this effect better than BMI. In this study, we examined applicability of models that adjusted handgrip-diabetes relationship with either BMI or FFM. Results Of 1940 participants (56.2% male, average (SD) age, 57.2 [11.2] years), 267 (13.8%) had diabetes (DM) and 912 (47.0%) had prediabetes (pre-DM). The average handgrip measure for men was 40.0 kg (tertile measures, 37.4 kg and 42.5 kg) and for women 24.2 kg (tertile measures, 22.6 kg and 25.7 kg). Among both sexes, the percentage of people unaffected by DM or pre-DM was highest in the strong handgrip group and lowest in the weak handgrip group. Analysis using binary logistic models showed that an increase in handgrip measure was associated with a decrease in the chance of having either pre-DM or DM. This effect was detected by both BMI models and FFM models, even after adjustment for medical and lifestyle factors. Either or both should be used depending on the research aims, setting and methods.

Abstract
UNLABELLED Few studies have examined the association between handgrip strength and BMD in specific subgroups. Therefore, we examined the associations of handgrip strength with BMD aged ≥ 40 years and found that handgrip strength is associated with BMD which is independent of BMI, physical activity, and other potential confounders. PURPOSE Previous studies have revealed that handgrip strength is a measure of muscular fitness and is associated with fracture and bone mineral density (BMD) in adolescents and adults, with conflicting results. In addition, few studies have examined the association between handgrip strength in predefined subgroups such as sex, age, and physical activity in a whole population. METHODS We examined the associations of handgrip strength with BMD in 2720 adults (1359 men and 1361 women) aged ≥ 40 years (mean age, 58.6 ± 11.8 years) from the National Health and Nutrition Examination Survey (NHANES) 2013-2014. NHANES collects data via household interviews and direct standardized physical examinations conducted in specially equipped mobile examination centers. The date of final data collection was 2014 and the present data analysis was conducted in January to February 2020. RESULTS Handgrip strength was significantly associated with total femur (r = 0.482, P < 0.001) and femoral neck BMD (r = 0.427, P < 0.001) among all participants, respectively. After adjustment for age, sex, race, body mass index (BMI), physical activity, smoking, history of diabetes, history of hypertension, and history of high cholesterol, each unit (1 SD) of BMI-adjusted handgrip strength was positively associated with 0.026 g/cm2 increase in total femur BMD (P < 0.001) and 0.027 g/cm2 increase in femoral neck BMD (P < 0.001). There was a significant increasing trend in total femur and femoral BMD as handgrip strength increased from the lowest quartile to the highest quartile (P for trend < 0.001). For subgroup analysis, there were no significant interaction effects of handgrip strength with BMD between predefined subgroups (all P > 0.05). CONCLUSIONS High level of handgrip strength is associated with increased BMD. The association is independent of BMI, physical activity, and other potential confounders.

Abstract
Background This study aimed to explore the level and changes in handgrip strength among preclinical Alzheimer’s disease (AD) and AD patients and to evaluate the association between handgrip strength and cognitive function. Methods A total of 1431 participants from the memory clinic of Shanghai JiaoTong University Affiliated Sixth People’s Hospital and community were enrolled in the final analysis, including 596 AD, 288 mild cognitive impairment (MCI), and 547 normal individuals (NC). All participants received a comprehensive neuropsychological assessment. Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment-Basic (MoCA-BC), and the Chinese version of Addenbrooke’s Cognitive Examination III (ACE-III-CV) were used as cognitive tests. The receiver operating characteristic curve (ROC) was plotted to assess the power of handgrip strength as a screening measure to discriminate AD and MCI. Results The results showed that handgrip strength in the MCI group was significantly lower than that of NC group, and the AD group had a further decline (both P < 0.01). Multivariate logistic regression was performed with the handgrip strength quartiles, and the results showed that the ORs of AD for increasing levels of handgrip strength were 1.00, 0.58 (0.46–0.78), 0.51 (0.36–0.73), and 0.50 (0.35–0.68), showing a decreasing trend (Pfor trend < 0.01). The ROC curve demonstrated that the handgrip strength cutoff points for the identification of AD were 16.8 and 20.7 kg among the female participants above and under 70 yrs and 24.4 and 33.3 kg for the male participants above and under 70 yrs, respectively. Similarly, for the identification of MCI, cutoff points were 17.5 and 21.9 kg for females above 70 yrs and under 70 yrs, and 25.8 and 36.2 kg for males above 70 yrs and under 70 yrs, respectively. Conclusions Our study provided the further knowledge on the relationship between noncognitive features and cognition in populations with differing cognitive status, revealed that the stronger handgrip strength was associated with better performances on cognitive function. It can be speculated that handgrip strength can help early recognition of Chinese AD patients.

Abstract
BACKGROUND Grip strength is an essential component of physical fitness. The objective of this study was to develop normative handgrip strength data for Iranian healthy boys and girls comparing their handgrip strength with international reference values. METHODS Handgrip strength was measured in 2637 healthy children/adolescents (1391 boys and 1246 girls), aged 7-18 years, using a standard adjustable Jamar hand dynamometer (Model 5030 J1, Sammons Preston Rolyan, Bolingbrook, IL, USA). Body mass (kg) and stature (cm) were measured and body mass index was computed in kg/m2. The sample was stratified by gender, age, and hand preference. RESULTS Handgrip strength increased with age and was considerably higher in boys than in girls for all age groups (p < 0.001). Grip strength had a parallel and linear growth for both genders until the age of about 11 years and showed a steeper upward slope in boys than in girls thereafter. The findings of the current investigation were significantly different from those of the previously published normative data, especially for boys over the age of 12 years and girls in the age range of 7-18 years (p < 0.001). This difference was mainly in such a way that the Iranians had lower handgrip strength. CONCLUSIONS The differences between present results and those of similar available in the literature in this field emphasize the significant role of using normative data specific to a particular population in research or clinical settings.

Abstract
BACKGROUND Diabetes is a major concern for the global health burden. This study aimed to investigate the relationship between handgrip strength (HGS) and the risk of new-onset diabetes and to compare the predictive abilities between relative HGS and dominant HGS. METHODS This longitudinal study used data from the Survey of Health, Ageing and Retirement in Europe (SHARE), including 66,100 European participants aged 50 years or older free of diabetes at baseline. The Cox proportional hazard model was used to analyze the relationship between HGS and diabetes, and the Harrell's C index, net reclassification index (NRI), and integrated discrimination improvement (IDI) were calculated to evaluate the predictive abilities of different HGS expressions. RESULTS There were 5,661 diabetes events occurred during follow-up. Compared with individuals with lowest quartiles, the hazard ratios (95 % confidence intervals) of the 2nd-4th quartiles were 0.88 (0.81-0.94), 0.82 (0.76-0.89) and 0.85 (0.78-0.93) for dominant HGS, and 0.95 (0.88-1.02), 0.82 (0.76-0.89) and 0.60 (0.54-0.67) for relative HGS. After adding dominant HGS to an office-based risk score (including age, gender, body mass index, smoking, and hypertension), the incremental values of the Harrell's C index, NRI, IDI of relative HGS were all slightly higher than those of dominant HGS in both training and validation sets. CONCLUSIONS Our findings supported that HGS was an independent predictor of new-onset diabetes in the middle-aged and older European population. Moreover, relative HGS exhibited a slightly higher predictive ability than dominant HGS.

Abstract
Background Low handgrip strength (HGS) is independently associated with a higher exacerbation risk in stable chronic obstructive pulmonary disease (COPD); however, the relationship between HGS while being admitted for COPD exacerbation and further exacerbation risk after discharge remains unclear. Methods We enrolled patients admitted for COPD exacerbation between January 2018 and June 2019. HGS tests were done within 3 days after admission. The primary endpoint was exacerbations within 12 months after the index admission, which needed emergency room visits or hospital admission. We analyzed the relationships among demographics, HGS, pulmonary function parameters, and acute exacerbation events. Results Among 43 enrolled patients, 31 (72.1%) participants (HGSw) had HGS weakness (22.1 ± 4.1 kg). The other 12 (27.9%) participants (non-HGSw) had the strength of handgrips 33.7 ± 3.1 kg. HGSw group showed a significantly higher rate of emergency room visits within 6, 9, and 12 months after the index admission than non-HGSw group (0.81 ± 1.30 vs. 0.08 ± 0.29, p = 0.045; 1.26 ± 1.59 vs. 0.17 ± 0.38, P = 0.019; 1.48 ± 1.86 vs. 0.25 ± 0.62, P = 0.027, respectively). There was a trend to have higher admission rate within 9 and 12 months in HGSw group, which did not achieve statistical significance (0.77 ± 1.38 vs. 0.08 ± 0.29, P = 0.064; 0.94 ± 1.56 vs. 0.08 ± 0.29, P = 0.062, respectively). Conclusions HGS weakness measured upon admission for COPD exacerbation was associated with a higher risk of exacerbation in the next year.
