Population-based reference values of handgrip strength and functional tests of muscle strength and balance in men aged 70–80 years

AbstractPurposeDecline of the sensory and motor systems in older people negatively affects postural control. This increases the risk of falls, which is dangerous for older people in long-term care. Being aware of the quality of postural control and the factors affecting it among elderly people, is crucial in implementing an effective fall-prevention program. This study aimed to measure postural control and the demographic, health-related, and functional factors presumed to be correlated with it among nursing home residents. Another aim was to find valid screening tools based on these factors.Materials and methodsSeventy one nursing home residents were included. Postural control was measured using the Berg Balance Scale. Grip strength, the 30-s chair stand test, and the Timed Up and Go test were used to measure global muscle strength, and functional mobility, respectively. The results of these functional tests were dichotomized using age-specific reference values.ResultsPostural control was significantly worse in those who did not reach the age-specific reference values in any of the three functional tests. Effect sizes were large for functional mobility and medium for muscle strength. Multimorbidity and gender had no effect on postural control in our sample.ConclusionsAmong nursing home residents, postural control is related to functional mobility and muscle strength. Thus, routine testing of these skills among elderly people is an important task of the physiotherapist.

Abstract Background Muscle deterioration is a hallmark of aging and sleep may play a role in the development of sarcopenia. Population-based studies including objective evaluation of sleep characteristics and disorders may provide evidence of how sleep affects muscle function across adulthood. We aimed to evaluate associations of sleep characteristics with handgrip strength in a population-based cohort study. Methods Participants of the HypnoLaus study (Lausanne, Switzerland) aged >40 years were cross-sectionally evaluated through questionnaires and PSG. Muscle strength was assessed by hand dynamometer and low muscle strength (LMS) was defined according to the criteria for sarcopenia (<27 kg for men, <16 kg for women). Multivariate logistic regression analysis controlling for potential confounders wereapplied. Results 1902 participants (mean [SD] age, 57.4 [10.5] years; 968 [50.9%] female) were enrolled. LMS was detected in 95 (5.0%) participants. After controlling for sociodemographic characteristics, lifestyle factors, and comorbidities, objectively measured long sleep duration (>8h) was independently associated with LMS (OR=2.41, 95%CI=1.36–4.27). Subjective measures of sleep duration and quality, excessive daytime sleepiness, and other sleep characteristics obtained by PSG were not associated with LMS. Conclusions Objectively measured long sleep duration rather than short sleep duration was associated with LMS in a population-based study including participants aged >40 years. Self-reported sleep duration was not associated with LMS. The findings suggest long sleep duration measured by PSG is a potential risk factor for sarcopenia and should be considered as a target in preventive and therapeutic strategies against the development of muscle health decline observed with aging.

Positive Effect

Sarcopenia is a major problem occurring in the aging population. Based on previous research, music appears to have a positive influence on many aspects of life, including physical performance. This led to the question of whether listening to self-selected favorite music could improve peripheral muscle strength in older people. In this crossover study, community-dwelling people aged 65 and older were included. All participants performed handgrip strength measurements in three different circumstances: while listening to their favorite music, their most disliked music, and no music at all. As the primary outcome measurement, the within-person differences in maximum handgrip strength between the three music conditions were analyzed. A total of 153 participants (aged 73.0 ± 6 years) were included. Listening to favorite music resulted in an increase in maximum handgrip strength of +0.87 kgf (0.54–1.21, p < 0.001) compared to no music, and of +0.97 kgf (0.56–1.37, p < 0.001) compared to least favorite music. Thus, listening to favorite music has a positive effect on handgrip strength in older people. Apart from its implications for scientific grip strength measurements, this effect may be used as a fun and innocent stimulant in rehabilitation and workout classes with seniors, which could be further tested in a range of older people.

Study Population

Background: Long-term associations between type 2 diabetes, prediabetes, and muscle strength are obscure in older adults. The aim of this study was to examine type 2 diabetes as a predictor of handgrip strength decline during an 11-year follow-up among men and women aged 55 years. Methods: We used Finnish population-based Health 2000 Survey and its follow-up measurements in 2011. The study population consisted of 1,200 individuals, aged 55–86 years at baseline. Baseline fasting glucose level or use of diabetes medication was used to categorize the participants into diabetes (≥7.0 mmol/L), prediabetes (≥6.1 mmol/L but <7.0 mmol/L), and nondiabetes (<6.1 mmol/L) groups. Handgrip strength was measured at baseline and during 11-year follow-up. Results: Mean handgrip strength at baseline did not differ between diabetes groups in men or women. Among men during the 11-year follow-up, decline in muscle strength was significantly greater among diabetes group (−131.5 Newtons [N], 95% confidence interval (CI) −182.7 to −80.4) than nondiabetes group (−98.9 N, 95% CI −139.5 to −58.3) after adjusting for age, education, lifestyle factors, chronic conditions, and diabetes status at follow-up. Among women, muscle strength decline did not differ between diabetes, prediabetes, or nondiabetes groups after adjusting for all potential covariates, the results being −45.0 N (95% CI −73.2 to −16.7), −29.4 N (95% CI −59.7 to 0.9), and −42.3 N (95% CI −70.5 to −14.1), respectively. Conclusions: The presence of type 2 diabetes was associated with greater muscle strength decline among older men but not among older women.

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.

Alcoholic Fatty Liver Disease

Although low socioeconomic status (SES) and decreased muscle strength have been found to be associated with the risk factors of non-alcoholic fatty liver disease (NAFLD), including insulin resistance, obesity, and metabolic syndrome, the associations among SES, muscle strength, and NAFLD are still unclear. We aimed to investigate the combined effect of SES and relative handgrip strength (HGS) on the risk of NAFLD in middle-aged adults. Data from 5272 middle-aged adults who participated in the Korea National Health and Nutrition Examination Surveys (KNHANES) from 2014–2018 were analyzed. NAFLD was defined using the hepatic steatosis index (HSI) > 36 and the comprehensive NAFLD score (CNS) ≥ 40 in the absence of other causes of liver disease. SES was based on a self-reported questionnaire. Overall, individuals with low SES (odds ratio (OR) = 1.703, 95% confidence interval (CI): 1.424–2.037, p < 0.001) or low HGS (OR = 12.161, 95% CI: 9.548–15.488, p < 0.001) had a significantly higher risk of NAFLD. The joint association analysis showed that a low SES combined with a low HGS (OR = 2.479, 95% CI: 1.351–4.549, p = 0.003) further significantly increased the risk of NAFLD when adjusted for all the covariates, compared with individuals with a high SES and a high HGS (OR = 1). The current findings suggest that both low SES and low HGS were independently and synergistically associated with an increased risk of NAFLD in middle-aged Korean adults.

AbstractHandgrip strength (HGS) is used as a biomarker for the state of health of older people, but the number of research publications containing the normative values of HGS in older adult populations is limited. The aim of the study was to define reference values and factors associated with HGS in older adults living in southeastern Poland. A cross-sectional study including 405 participants aged 65 and older was conducted. Handgrip strength for the dominant hand was assessed by the average of three trials using a JAMAR dynamometer. The sample was categorized into the following age groups: 65–69 years, 70–74 years, 75–79 years, 80–84 years, 85 and over. The average HGS was 19.98 kg (16.91 kg for women and 26.19 kg for men). There was a decrease in handgrip strength across the age range in both sexes. The average handgrip strength of the older people was 17.97 kg (14.47 kg for women and 25.66 kg for men) for those aged 80–85 and 16.68 kg (13.51 kg for women and 21.77 kg for men) in the group over 85 years old. In both sexes, marital status was an independent factor associated with reduced handgrip strength. In conclusion, this study described, for the first time, handgrip strength values for the southeastern Polish population aged ≥ 65 years according to age and gender.
