The relationship between grip strength and muscle mass (MM), inflammatory biomarkers and physical performance in community-dwelling very old persons

ObjectiveTo examine the relationship between different measures of testosterone and estradiol (E2), muscle mass, muscle strength, and physical performance; and to test whether the association of sex hormone level with muscle strength and physical performance was independent of muscle mass.Design and methodsA cross-sectional survey on 1489 community-dwelling men older than 64 years of age. Serum levels of testosterone and E2were measured by mass spectrometry, and sex hormone-binding globulin (SHBG) levels were measured by immunoradioassay. Muscle mass was examined by dual-energy X-ray absorptiometry and physical performance was assessed by hand-grip strength, gait speed, step length and chair-stand test.ResultsAppendicular skeletal mass (ASM) was positively associated with total testosterone (TT;P<0.001), free testosterone (FT;P<0.001), and total E2(P<0.001) but not with free E2(P=0.102). After adjustment for age, serum SHBG and relative ASM, both TT and FT were significantly associated with grip strength, narrow-walk speed and the composite neuromuscular score. Higher total E2, but not free E2was associated with lower grip strength (P<0.05) after adjustment for age, FT, SHBG and relative ASM.ConclusionsTestosterone level was related to both muscle mass, strength and physical performance. Total E2level, though related to muscle mass positively, affected muscle strength adversely in older men.

Abstract Background Growth and differentiation factor 15 (GDF-15) has been associated with obesity, muscle wasting, and cachexia. The receptor for GDF-15 was recently identified in the brainstem and regulates food intake and metabolism. The relationship of plasma GDF-15 with the age-associated decline of muscle mass and strength, gait speed, and physical performance in adults has not been well characterized. Methods Plasma GDF-15, grip strength, 6-m gait speed, 400-m walking test time, lower extremity physical performance score, appendicular lean mass, and fat mass were measured in 194 healthy adult participants, aged 22–93 years, of the Baltimore Longitudinal Study of Aging. Results Plasma GDF-15 concentrations increased with age (p < .001) and were higher in whites compared with blacks and Asians (p = .04). Adults with higher plasma GDF-15 had slower 6-m gait speed, longer 400-m walking time, and lower physical performance score in multivariable analyses adjusting for age and race. Plasma GDF-15 was not associated with grip strength, appendicular lean mass, or fat mass. Conclusions Elevated plasma GDF-15 is associated with slower gait speed, higher 400-m walking time, and lower physical performance in very healthy community-dwelling adults. The relationship between plasma GDF-15 and sarcopenia-related outcomes may be stronger in the population not selected to be healthy, and this hypothesis should be tested in a representative population.

Usual Gait Speed

Abstract To investigate the relationship between perceived physical and mental fatigability and physical performance in community-dwelling very old adults (≥80 years). We examined the association in one retired community in Beijing including 404 very old adults. Pittsburgh Fatigability Scale (PFS), Chinese version, was used to assess perceived fatigability in physical domain (PFS-P) and mental domain (PFS-M). High fatigability is defined as PFS-P ≥ 15, and PFS-M ≥ 13. Physical performance measures include grip strength, usual gait speed, chair stand and Short Physical Performance Battery (SPPB) test. Women have higher PFS scores (both PFS-P & PFS-M) and higher prevalence of high fatigability than men. After adjusting for sex, usual gait speed and SPPB scores were significantly associated with PFS-P & PFS-M, while grip strength and chair stand performance were significantly associated with PFS-P only. After multivariable adjustment, usual gait speed (B=-3.745, P=0.021) and chair stand performance (B=0.335, P=0.005) were significantly associated with PFS-P, while usual gait speed (B=-2.656, P=0.006) and SPPB scores (B=-0.214, P=0.029) were significantly associated with PFS-M. Perceived physical and mental fatigability is highly prevalent in very older adults and they differ by sex. The significant associations between PFS scores and performance measures suggest that PFS is of potential clinical importance, especially when testing performance measures are not feasible. Utilization of PFS score can assist in identifying target populations who are at risk of reduced physical functions, such as older with depression, older women. Interventions to improve usual gait speed are likely to reduce both perceived physical and mental fatigability.

Abstract Background The sit-to-stand (STS) test has been deployed as surrogate measures of strength or physical performance in sarcopenia diagnosis. This study examines the relationship of two common STS variants – Five Times Sit-to-Stand Test (5TSTS) and 30 s Chair Stand Test (30CST) – with grip strength, muscle mass and functional measures, and their impact on sarcopenia prevalence in community-dwelling older adults. Methods This is a cross-sectional analysis of 887 community-dwelling adults aged ≥50 years. Participants completed a battery of physical fitness tests - 5TSTS, 30CST, grip strength, gait speed, Timed-Up-and-Go (TUG) for dynamic balance and six-minute walk test (6MWT) for cardiorespiratory endurance. Muscle mass was measured using multi-frequency segmental bioelectrical impedance analysis (BIA). We performed correlation analysis between STS performance and other fitness measures and muscle mass, followed by multiple linear regression for the independent determinants of STS performance. Results Mean participant age was 67.3±7 years, with female predominance (72.9%). STS tests exhibited weak correlations with grip strength (30CST, r = 0.290; 5TSTS, r = − 0.242; both p< 0.01), and stronger correlations with gait speed (30CST, r = 0.517; 5TSTS, r = − 0.533; both p< 0.01), endurance (30CST, r = 0.558; 5TSTS, r = − 0.531; both p < 0.01) and dynamic balance (30CST, r = − 0.501; 5TSTS, r = 0.646; both p< 0.01). Muscle mass correlated with grip strength but not STS. In multiple regression analysis, all fitness measures were independently associated with 30CST performance. Performance in both STS tests remained independent of muscle mass. There was no significant difference in prevalence of possible sarcopenia diagnosis using grip strength or STS (30CST, 25.0%; 5TSTS, 22.1%; grip strength, 22.3%; p = 0.276). When both measures are used, prevalence is significantly higher (42.0%; p = 0.276). Prevalence of confirmed sarcopenia with inclusion of muscle mass was significantly lower using STS compared with grip strength (30CST, 4.6%; 5TSTS, 4.1% vs. grip strength, 7.1%; p< 0.05). Conclusion In the sarcopenia construct, STS tests better represents muscle physical performance rather than muscle strength. Different subsets of population with possible sarcopenia are identified depending on the test used. The lack of association of STS performance with muscle mass results in a lower prevalence of confirmed sarcopenia compared with grip strength, but may better reflect changes in muscle quality.

Abstract Background: Both sarcopenia and loss of teeth are associated with aging. The purpose of this study was to investigate potential relationships between tooth loss and sarcopenia and components of sarcopenia, including declining muscle mass, muscle strength, and physical performance, in Chinese suburban community-dwelling older adults.Methods: The subjects were 1494 people over 60 years of age (average age: 71.64 ± 5.97 years；men, n=609) from Chongming District of Shanghai and Hangu District of Tianjin. The Asian Working Group for Sarcopenia (AWGS) criteria were used to define sarcopenia. The three basic diagnostic components of sarcopenia (muscle mass, muscle strength, and physical performance) were assessed using a bioelectrical impedance analyzer, a grip strength test, and a four-meter walk test, respectively. The subjects were divided into groups depending on self-reported loss of teeth. Results: After adjusting for confounding variables, we found no correlation between tooth loss and sarcopenia or muscle mass. However, the walking speed of female participants with at least 10 teeth lost was 0.059 m/s slower than that of participants with fewer than 10 teeth lost (P＜0.001), and grip strength was 1.577 kg lower among male participants with at least 10 teeth lost than among males with fewer than 10 teeth lost (P =0.023).Conclusion: Our results suggest that tooth loss is negatively correlated with muscle strength in males and average walking speed in females. These results are consistent with the importance of good oral hygiene in preventing declines of physical performance in older adults.

Introduction: Reduced tongue pressure is one of the causes of dysphagia. The purpose of this study was to investigate the relationship between dental findings and tongue pressure, and whether prosthetic treatment prevents reduced tongue pressure. Methods: This was a cross-sectional study. Participants were 745 community-dwelling adults and elderly persons in the Goto Islands in Nagasaki, who underwent a health checkup for residents in 2015 and 2016. Data were collected on gender; age; grip strength; hemoglobin; Creatinine (Cr); glycated hemoglobin (HbA1c); history of stroke; smoking, drinking, exercise, and walking habits; number of teeth; wearing of removable dentures; functional units of natural teeth (n-FTUs), fixed prostheses (nif-FTUs), and removable dentures (t-FTUs); and tongue pressure. The associations between each variable and tongue pressure were examined using multiple regression analysis. Next, those with 3 or fewer n-FTUs were selected, and differences in tongue pressure were compared between those with 3 or fewer nif-FTUs and those with 4 or more nif-FTUs, using a propensity score matching method. Results: Male gender, weak grip strength, low HbA1c, no drinking, and a low number of teeth were independent factors significantly associated with lower tongue pressure. Among participants with 3 or fewer n-FTUs, the 43 with 4 or more nif-FTUs showed significantly higher tongue pressure than the 43 with 3 or fewer nif-FTUs after propensity score matching, although the number of t-FTUs was not associated with tongue pressure. Discussion/Conclusion: Tooth loss was significantly associated with lower tongue pressure. It was suggested that fixed prosthesis treatment might prevent the reduction of tongue pressure, but removable dentures did not have such an effect.

Abstract Background Growth differentiation factor 15 (GDF15) has been associated with several age-related disorders, but its associations with functional abilities in community-dwelling older adults are not well studied. Methods The study was a secondary analysis on 1096 community-dwelling older adults (aged 69 to 94 years) recruited from the Multidomain Alzheimer’s Preventive Trial. Plasma GDF15 was measured one year after participants’ enrolment. Annual data of physical performance (grip strength and short physical performance battery [SPPB]) and global cognitive functions (mini-mental state examination [MMSE] and a composite cognitive score) were measured for four years. Adjusted mixed-effects linear models were performed for cross-sectional and longitudinal association analyses. Results A higher GDF15 was cross-sectionally associated with a weaker grip strength (β = -1.1E-03, 95%CI [-2.0E-03, -1.5E-04]), a lower SPPB score (β = -3.1E-04, 95%CI [-5.4E-04, -9.0E-05]) and worse cognitive functions (β = -2.4E-04, 95%CI [-3.3E-04, -1.6E-04] for composite cognitive score; β = -4.0E-04, 95%CI [-6.4E-04, -1.6E-04] for MMSE). Participants with higher GDF15 demonstrated greater longitudinal declines in SPPB (β = -1.0E-04, 95%CI [-1.7E-04, -2.0E-05]) and composite cognitive score (β = -2.0E-05, 95%CI [-4.0E-05, -3.6E-06]). The optimal initial GDF15 cutoff values for identifying participants with minimal clinically significant decline after one year were 2189 pg/mL for SPPB (AUC: 0.580) and 2330 pg/mL for composite cognitive score (AUC: 0.587). Conclusions Plasma GDF15 is cross-sectionally and longitudinally associated with lower-limb physical performance and global cognitive function in older adults. Circulating GDF15 alone has limited capacity of discriminating older adults who will develop clinically significant functional declines.

Abstract Background: Prolonged healthy life expectancy, which is duration without the requirement of any kind of help for activities of daily living (ADL), is essential to ensure a long life with a good quality of living in the community. Further, local residents should understand their health conditions and live consciously to prolong healthy life expectancy. The development of a simple general health indicator is necessary. Both occlusal force and flow-medicated dilation (FMD) which reflects endothelial function are useful tools for understanding the general condition of the elderly. However, few studies have investigated the relationship between occlusal force and endothelial function. In the present study we examined this relationship, occlusal force measurement can be a good indicator of the general condition of the elderly. Methods: In 38 community-dwelling women(aged 76.7 ±5.7 years), we measured occlusal force,　grip strength, endothelial function evaluated by FMD, advanced glycation end products (AGEs). In this study we investigate we investigated the relationship between occlusal force, measurement items, and factors independently related to endothelial dysfunction (FMD<7％). Results: There were significantly correlation between occlusal force and grip strength (r=0.54, p<0.01). Degree of FMD significantly associated with occlusal force (r=0.60, p<0.01) and grip strength (r=0.35, p<0.05) or amount of increased AGEs (r=-0.37, p<0.05). Occlusal force was independently associated with degree of FMD after adjusting for age, AGEs, and grip strength (p < 0.05).Conclusion: There was a significant relationship between occlusal force and FMD. Occlusal force can be an important indicator of endothelial function in community-dwelling elderly. This study may help understanding general health of elderly in community.

Abstract Background Evaluating physical performance could facilitate dementia risk assessment. However, findings differ regarding which type of physical performance best predicts dementia. Objective The objective of this study was to examine the association between physical performance and incidence of dementia in Japanese community-dwelling older adults. Design This was a prospective study of community-dwelling older adults. Methods Of 14,313 invited individuals who were ≥ 65 years old, 5104 agreed to participate from 2011 to 2012, and 4086 (52% women; mean age = 72.0 years) met the criteria. Baseline assessments of the following physical performance indicators were obtained: grip strength, the Five-Times Sit-to-Stand Test, and the Timed “Up & Go” Test. The physical performance level in each test was categorized as C1 (highest), C2 (middle–high), C3 (middle–low), or C4 (lowest) on the basis of sex-stratified quartile values. Incident dementia status was obtained from medical records that were updated monthly. Results During follow-up (mean duration = 42.9 months), there were 243 incident cases of dementia (5.9%). Log-rank test results indicated that a lower physical performance level constituted a significant risk factor for dementia. After adjustment for covariates, Cox proportional hazards models (reference: highest physical performance level [C1]) demonstrated that the Five-Times Sit-to-Stand Test in the group with the lowest physical performance level (hazard ratio = 1.69; 95% CI = 1.10–2.59) was significantly associated with a risk of dementia. Likewise, the Timed “Up & Go” Test in the group with the lowest physical performance level (hazard ratio = 1.54; 95% CI = 1.01–2.35) was significantly associated with a risk of dementia. However, grip strength was not significantly associated with a risk of dementia. Limitations This study was limited by the use of medical record data. Conclusions A lower mobility-related physical performance level was associated with dementia risk. Dementia risk assessment should include an adequate evaluation of physical function.
