ABSTRACT

SUMMARY: The handgrip strength is used as a means of individual's health prediction during life. It is used as an indicator of the nutrition status, bone fragility, presence of sarcopenia and it correlates with certain diseases and clinical complications. The research goal was to analyze the results of the hand dynamometry test, based on the chronological and biological age, and to offer normative and referent standards about children and adolescents from the Republic of North Macedonia. The study was conducted on a sample of 4031 respondents of both sexes at the age 6-14 years. In order to achieve the research goals, the measured characteristics were of the weight, height, sitting height and handgrip strength. The body mass index and biological maturity values (APHV) were obtained by using formulas. On the basis of the obtained results, it can be concluded that statistically significant differences in handgrip strength are established between the boys and girls of all age categories. Also, statistically significant differences between boys and girls are established in the hand dynamometry test of all APHV levels. In general, the use of the APHV allows a better categorization of the performance of the studied children and adolescents. With boys, the correlation between the chronological age and test was 68 %, and with girls - 77 %. The normative referent standards of the hand dynamometry test are presented in percentiles for both sexes. Thye hand dynamometry test's results during childhood and adolescence should be analyzed and interpret on the basis of biological age, and not on the chronological age. These tools can help specialists who work with children and adolescents in ethnic and epidemiological context.


La fuerza de prensión se utiliza como medio para predecir la salud del individuo durante la vida. Se utiliza como indicador del estado nutricional, fragilidad ósea, presencia de sarcopenia y se correlaciona con determinadas enfermedades y complicaciones clínicas. El objetivo de la investigación fue analizar los resultados de la prueba de dinamometría manual, con base en la edad cronológica y biológica, y ofrecer estándares normativos y referentes sobre niños y adolescentes de la República de Macedonia del Norte. El estudio se realizó en una muestra de 4031 encuestados de ambos sexos con edades comprendidas entre 6 y 14 años. Para lograr los objetivos de la investigación, las características medidas fueron el peso, la altura, la altura al sentarse y la fuerza de prensión. El índice de masa corporal y los valores de madurez biológica (APHV) se obtuvieron mediante fórmulas. Sobre la base de los resultados obtenidos, se puede concluir que se establecen diferencias estadísticamente significativas en la fuerza de prensión manual entre niños y niñas de todas las categorías de edad. Asimismo, se establecen diferencias estadísticamente significativas entre niños y niñas en la prueba de dinamometría manual de todos los niveles APHV. En general, el uso del APHV permite una mejor categorización del desempeño de los niños y adolescentes estudiados. En los niños, la correlación entre la edad cronológica y la prueba fue del 68 %, y en las niñas, del 77 %. Los estándares normativos referentes de la prueba de dinamometría manual se presentan en percentiles para ambos sexos. Los resultados de la prueba de dinamometría manual durante la infancia y la adolescencia deben analizarse e interpretarse en función de la edad biológica y no de la edad cronológica. Estas herramientas pueden ayudar a los especialistas que trabajan con niños y adolescentes en un contexto étnico y epidemiológico.

ABSTRACT

OBJECTIVE@#This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength.@*METHODS@#We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.@*RESULTS@#In the multimetal linear regression, Cu (β = -2.119), As (β = -1.318), Sr (β = -2.480), Ba (β = 0.781), Fe (β = 1.130) and Mn (β = -0.404) were significantly correlated with grip strength ( P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95% confidence interval: -1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn ( P interactions of 0.003 and 0.018, respectively).@*CONCLUSION@#In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

ABSTRACT

ABSTRACT Muscle weakness has been associated to insulin resistance and metabolic syndrome in the general population. However, it is still unclear whether this association is maintained in older adults. This study investigated correlations between low handgrip strength (HGS) and metabolic syndrome, or some of its components, in older adults through a systematic review of the literature. Searches were conducted in the Virtual Health Library Regional Portal, Scopus, Cochrane, Embase, MEDLINE/PubMed, SciELO, and Web of Science databases for relevant studies investigating muscle weakness (measured by hand dynamometer) and metabolic syndrome or its components in older adult populations, published up to September 2023. From the 2050 references initially identified, 20 studies, comprising a total of 31,264 older adults of both genders, completely met the inclusion/exclusion criteria. Eighteen studies showed that lower HGS was associated with metabolic syndrome or some of its risk factors, such as abdominal obesity, hyperglycemia, insulin resistance, dyslipidemia, or high blood pressure. Two studies found that older men with high blood pressure had increased HGS. Most studies included in this systematic review revealed a significant correlation between reduced HGS and metabolic syndrome or some of its components, especially abdominal obesity and insulin resistance. We conclude that below-average HGS can be associated with metabolic syndrome in older adults.

ABSTRACT

Abstract Introduction: Monitoring the functional capacity of older adults is fundamental, and Handgrip Strength (HGS) is a consolidated marker of functional status in this age group. This study aimed to develop equations for predicting HGS in community-dwelling older adults in Primary Health Care (PHC). Methods: It is a cross-sectional study conducted with 316 older adults, in which a Multiple Linear Regression (MLR) was performed for the right hand (R-HGS) and left hand (L-HGS). The variables sex, age, weight, knee height (KH), arm circumference (AC), triceps skinfold (TSF), and calf circumference (CC) were considered predictors because they were easily obtained in PHC and significantly related to HGS. Results: In the final models, the variables sex, age, and KH together explained more than 50 % of the HGS variation. There was agreement between the estimated and measured HGS measurements, both for right and left side. Conclusions: It is concluded that the variability of HGS can be explained by age, sex, and KH, which are parameters simple and routinely used to evaluate older adults.


Resumen Introducción: El monitoreo de la capacidad funcional de adultos mayores es fundamental, y la Fuerza de Prensión Manual (FPM) es un buen indicador de la condición física en este grupo de edad. El objetivo de este estudio fue elaborar ecuaciones de predicción de la FPM en una comunidad de personas adultas mayores en la Atención Primaria de Salud (APS). Métodos: estudio transversal realizado con 316 personas adultas mayores, en el cual se desarrolló una Regresión Linear Múltiple (RLM) para la mano derecha (FPMd) e izquierda (FPMi). Las variables sexo, edad, peso, altura de la rodilla (AR), circunferencia del brazo (CB), pliegue cutáneo tricipital (PCT) y circunferencia de la pantorrilla (CP) fueron consideradas predictoras, pues son fácilmente obtenidas en la APS y significativamente relacionadas con la FPM. Resultados: las variables sexo, edad y AR en conjunto explicaron más del 50% de la variación de la FPM. Hubo concordancia entre las medidas de la FPM estimada y la medida real, tanto en la mano derecha cuanto en la mano izquierda. Conclusión: La variabilidad de la FPM puede ser explicada por la edad, sexo y AJ, parámetros simples y comúnmente utilizados en las evaluaciones de salud de personas adultas mayores.

ABSTRACT

El diagnóstico por bioimpedancia (BIA) y el ángulo de fase (AnF), como indicador, permiten monitorear el estado físico, de salud y nutricional en adultos mayores. El objetivo de este estudio fue establecer la relación entre la condición física y valores de fase angular por bioimpedancia en un grupo de adultos mayores sedentarios. Participaron voluntariamente 24 adultos mayores sedentarios (21 mujeres y 3 hombres). A cada participante se les midió bioimpedancia, fuerza de presión manual y test de 6 minutos del Senior Fitness Test (SFT). Posteriormente se analizaron los resultados, correlacionando el ángulo de fase (AnF) y condición física cardiorrespiratoria según sexo y el AnF con la fuerza de presión manual. El 71% presentó una media de AnF por debajo de la referencia (4,5º ± 0,4), específicamente, el 67% de los hombres y el 62% de las mujeres. La correlación entre AnF y capacidad física cardiorrespiratoria arrojó un valor de R2= 0,50; p<0,0001. La asociación entre AnF y fuerza de presión manual fue de R2=0,35; p=0,0023. Se encontró una relación significativa entre una prueba de condición física cardiorrespiratoria y AnF y entre la fuerza de presión manual y AnF. Es de importancia clínica incluir parámetros objetivos de valoración celular en adultos mayores como el AnF.


The diagnosis by bioimpedance (BIA) and the phase angle (PhA) are indicators, that allow monitoring of the physical health and nutritional status of older adults. The objective of this study was to establish the relationship between physical fitness and phase angle values by bioimpedance in a group of sedentary older adults. 24 elderly sedentary volunteers participated (21 women and 3 men). Each participant underwent bioimpedance, manual dynamometry, and the 6-minute Senior Fitness Test (SFT). Subsequently, the results were analyzed, making a correlation between PhA and cardiorespiratory physical condition, another between PhA and cardiorespiratory physical condition according to sex and finally an association between PhA and handgrip strength. R71% presented a PhA mean below the reference (4.5º ± 0.4), specifically 67% of men and 62% of women. The correlation between PhA and cardiorespiratory fitness showed a value of R2= 0.50; p<0.0001. The association between PhA and handgrip strength was R2=0.35; p=0.0023. A significant relationship was found between a cardiorespiratory fitness test and PhA and between handgrip strength and PhA. It is of clinical importance to include objective cellular assessment parameters in older adults such as PhA.

ABSTRACT

Abstract The study aims to investigate the independent association of muscle mass (MM) and bone mineral content (BMC) in the performance of the handgrip strength (HGS) test and whether there is effect modification by sex and age. In 12,491 participants from the ELSA-Brasil we estimated the associations between MM, BMC and HGS using linear regression models. All the analyses were performed for total population, also stratified for sex and age. For total population an interaction term was included between each explanatory variable of interest with sex and age to verify the presence of effect modification. We observed that the higher quintiles of MM and BMC were associated to an increasing in the mean of HGS compared to the first quintile, with greater magnitudes in men compared to women, also adults compared to elderly. When we estimated the independent effect of each exposure of interest, MM showed stronger effect in HGS in women, men and adults then BMC. In conclusion, we observed that higher amounts of MM and BMC are associated with higher HGS, regardless of sociodemographic characteristics, health conditions and lifestyle, with this effect being greater in men and adults.


Resumo O estudo tem como objetivo investigar a associação independente da massa muscular (MM) e conteúdo mineral ósseo (CMO) na realização do teste de força de preensão manual (FPM) e se há modificação do efeito por sexo e idade. Em 12.491 participantes do ELSA-Brasil estimamos as associações entre MM, CMO e FPM usando modelos de regressão linear. Todas as análises foram realizadas para a população total, também estratificada por sexo e idade. Para a população total foi incluído um termo de interação entre cada variável explicativa de interesse com sexo e idade para verificar a presença de modificação de efeito. Observamos que os maiores quintis de MM e BMC estiveram associados a um aumento na média da FPM em relação ao primeiro quintil, com maiores magnitudes em homens em relação a mulheres, também em adultos em relação a idosos. Quando estimamos o efeito independente de cada exposição de interesse, MM mostrou efeito mais forte na FPM em mulheres, homens e adultos do que BMC. Em conclusão, observamos que maiores quantidades de MM e BMC estão associadas a maior FPM, independentemente das características sociodemográficas, condições de saúde e estilo de vida, sendo esse efeito maior em homens e adultos.

ABSTRACT

Introdução: a Força de Preensão Manual (FPM) é um indicador de saúde e funcionalidade do idoso, que diminui com o passar do tempo, impactada por aspectos como mudanças na composição corporal. Objetivo: investigar a associação entre o Ângulo de Fase Padronizado (AFP) e FPM em idosos comunitários da Atenção Primária à Saúde (APS). Metodologia: estudo transversal, com pessoas de 60 anos ou mais, atendidos na APS. A variável dependente foi a FPM medida com dinamômetro e a independente principal foi o AFP com base no sexo e faixa etária, calculado a partir do ângulo de fase obtido pela bioimpedância. Foi realizada a regressão logística com entrada por bloco, sendo incluídas no modelo as variáveis que apresentaram associação com nível crítico menor do que 10%. Resultados: dos 296 indivíduos avaliados, 28,0% exibiram baixa FPM e 15,9% apresentaram AFP < ­ 1,65°. As variáveis inseridas no modelo final de regressão logística, juntamente com o AFP, foram sexo, faixa etária, Índice de Massa Corporal (IMC) e Circunferência da Panturrilha (CP). A análise mostrou que o AFP < ­ 1,65° aumenta a chance do idoso apresentar baixa FPM, tanto na análise sem ajuste (OR = 2,71; IC 95% 1,43-5,15), quanto no modelo final (OR = 2,35; IC 95% 1,14-4,87). Conclusão: o AFP mostrou-se associado à FPM, independentemente da interação com sexo, faixa etária, IMC e CP. A sua utilização pode contribuir na avaliação de idosos, especialmente quando a aferição da FPM não for possível.


Introduction: Handgrip Strength (HGS) is an indicator of health and functionality of the older adults, which decreases over time, impacted by aspects including changes in body composition. Objective: to investigate the association between the Standardized Phase Angle (SPA ) and HGS in community-dwelling older adults in Primary Health Care (PHC). Methodology: cross-sectional study, with people aged 60 or over, assisted in the PHC. The dependent variable was the HGS measured using a dynamometer. The main independent variable was the SPA based on gender and age range, calculated from the phase angle obtained by bioimpedance. Block-by-block logistic regression was performed, including variables that were associated with a critical level lower than 10% in the model. Results: of the 296 individuals assessed, 28.0% had low HGS and 15.9% had SPA < ­ 1.65°. The variables inserted in the final logistic regression model, together with the SPA , were gender, age group, Body Mass Index (BMI) and Calf Circumference (CC). The analysis showed that SPA < ­ 1.65° increases the chance of the older adults having low HGS, both in the unadjusted analysis (OR = 2.71; 95% CI 1.43-5.15) and in the final model (OR = 2.35; 95%CI 1.14-4.87). Conclusion: the SPA was associated with HGS, regardless of the interaction with sex, age group, BMI and CC. Its use can contribute to the evaluation of the older adults, especially when HGS measurement is not possible.

ABSTRACT

ObjectiveTo obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia (AWGS2019), and to further explore the association between sarcopenia and metabolic syndrome (MS). MethodsA total of 1 438 middle-aged and elderly people (aged≥50 years) in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey, physical examination and laboratory test. Skeletal muscle mass,grip strength and 4 m walking speed were used to represent muscle mass, muscle strength and body function, respectively. Bioelectrical impedance analysis (BIA) was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019, the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders. ResultsThere were 194 patients with sarcopenia, with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group (40.45%) and non-sarcopenia group (38.92%), while the prevalence of MS in female sarcopenia group (39.04%) was higher than that in non-sarcopenia group (27.56%). Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia, the risk of MS in male sarcopenia group was higher (OR=2.11,95%CI: 1.15‒3.88 ). ConclusionSarcopenia increases the risk of MS in middle-aged and elderly people, with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.

ABSTRACT

Background: Handgrip strength is the maximum force produced during a maximal voluntary contraction (MVC) handgrip strength (HGS). The handgrip dynamometer is used to work out upper-body muscles, particularly those in the forearm and hand. HGS is frequently used as an objective measure of upper extremity functional integrity. HGS is a physiological characteristic influenced by a variety of parameters such as gender, age, and body size. Aims and Objectives: The objective of th study was to assess and compare HGS in healthy first-phase male and female medical subjects. Materials and Methods: In a cross-sectional research, 250 healthy 1st-year medical students between the ages of 17 and 20 participated. Maximum HGS was measured using a handgrip dynamometer. The grip strength of the dominant hand was assessed 3 times at minute intervals, as suggested by the American Society of Hand Therapists, with the higher value (in kg) reflecting the maximal HGS for each. Results: In comparison to female subjects (Mean: 31.87 kg), HGS in male subjects (Mean: 41.85 Kg) was statistically significant (P < 0.001). There was a statistically significant difference in height, weight, and body mass index between men and women, despite the fact that there was no statistically significant difference in mean age. Conclusion: Male individuals had stronger grips than female ones. The purpose of this study is to provide a baseline of normative data (control values) among a sample cohort of GMC Jammu medical students. This study, however, was confined to medical students between the ages of 17 and 20. We believe that diverse age groups should be studied.

ABSTRACT

Resumo: Trata-se de estudo quantitativo transversal cujo objetivo foi analisar a correlação entre funcionalidade e força de preensão manual e a condição de fragilidade física em idosos da atenção primária à saúde. Participaram 389 idosos (=60 anos) de ambos os sexos, cadastrados em uma Unidade Básica de Saúde de Curitiba, Paraná. A coleta de dados ocorreu de janeiro a novembro de 2019, foi precedida pela aplicação do miniexame do estado mental, seguida dos questionários sociodemográfico e clínico, escala da medida de independência funcional (MIF) e avaliação da fragilidade física. Os dados foram organizados no programa Microsoft Excel® 2007 e analisados no software R CORE TEAM, mediante estatística descritiva, análises bivariadas (p<0,05), testes de Kruskal-Wallis, Dunn, qui-quadrado e Spearman. Dos 389 idosos, 34 (8,7%) eram frágeis, 186 (47,8%) pré-frágeis, 169 (43,5%) não frágeis, 255 (65,6%) do sexo feminino e 186 (47,8%) na faixa etária entre 60 e 69 anos. A FPM reduzida foi identificada em 82 (21%) idosos e distribuída entre 27 (79,5%) frágeis e 55 (29,5%) pré-frágeis. Houve correlação significativa entre funcionalidade e força de preensão manual segundo à condição de fragilidade física (Pˆ= 0,330; p=<0,001). A média da FPM foi maior no grupo de idosos não frágeis (28,9 Kgf), comparada aos pré-frágeis (24,6 Kgf) e frágeis (17,1 Kgf). A pontuação média da funcionalidade (MIF) foi maior no grupo de idosos não frágeis (122,1 pontos) em relação aos pré-frágeis (120,6pontos) e frágeis (114,2 pontos). Quanto à tarefa da MIF "controle de urina", observou-se elevada frequência idosos frágeis completamente dependentes (n=9; 26,4%) e pré-frágeis moderadamente dependentes (n=52; 27,9%). Para a tarefa "interação social" observou-se expressiva frequência de idosos frágeis moderadamente dependentes(n=12; 35,3%). Para a tarefa "resolução de problemas" evidenciou-se a mesma frequência (n=7; 20,6%) de idosos frágeis completamente dependentes e moderadamente dependentes. Na avaliação da tarefa "memória" destacaram-se os pré-frágeis moderadamente dependentes (n=26; 14%). A correlação entre funcionalidade (MIF) e FPM se mostrou fraca, positiva e significativa entre os idosos da amostra investigada (Pˆ= 0,330; p=<0,001), entre os não frágeis (Pˆ= 0,252;p=<0,001) e entre os pré-frágeis (Pˆ= 0,236; p=0,001). O desempenho nas tarefas "controle de urina" e "subir e descer escadas" correlacionou-se significativamente à FPM (p=<0,005) entre os idosos pré-frágeis. Destacam-se, com maior coeficiente de correlação com a FPM, as tarefas "controle de urina" para os idosos não frágeis (Pˆ=0,309) e "subir e descer escadas" para os pré-frágeis (Pˆ=0,222). Já a tarefa "resolução de problemas" correlacionou-se à FPM entre os idosos pré-frágeis (p=<0,004) e frágeis (p=<0,017), sendo entre esses o maior coeficiente de correlação (Pˆ= 0,408). Verifica-se ainda a correlação entre a tarefa "expressão verbal e não verbal" e a FPM para o grupo de idosos frágeis (p=<0,025; Pˆ= 0,383). Conclui-se que houve correlação positiva entre funcionalidade e FPM entre os idosos não frágeis e pré-frágeis, indicando que quanto maior a FPM, melhor é o desempenho funcional. Destacam-se resultados expressivos para a prática clínica de enfermagem gerontológica, que podem subsidiar estratégias preventivas voltadas à manutenção da FPM e da funcionalidade, principalmente entre os idosos não frágeis e pré-frágeis.


Abstract: This is a cross-sectional quantitative study whose objective was to analyze the correlation between functionality and handgrip strength and the condition of physical frailty in elderly people in primary health care. Participants were 389 elderly people (=60 years) of both sexes, registered at a Basic Health Unit in Curitiba, Paraná. Data collection took place from January to November 2019, was preceded by the application of the mini-mental state exam, followed by sociodemographic and clinical questionnaires, functional independence measure scale (FIM), and assessment of physical frailty. Data were organized in Microsoft Excel® 2007 program and analyzed in R CORE TEAM software, using descriptive statistics, bivariate analyzes (p<0.05), Kruskal-Wallis, Dunn, chi-square, and Spearman tests. Of the 389 elderly, 34 (8.7%) were frail, 186 (47.8%) were pre-frail, 169 (43.5%) were non-frail, 255 (65.6%) were female and 186 (47.8%) in the age group between 60 and 69 years. Reduced HGS was identified in 82 (21%) elderly and distributed among 27 (79.5%) frail and 55 (29.5%) pre-frail. There was a significant correlation between functionality and handgrip strength according to the condition of physical frailty (Pˆ=0.330; p=<0.001). The average HGS was higher in the group of non-frail elderly (28.9 Kgf), compared to pre-frail (24.6 Kgf) and frail (17.1 Kgf). The mean functionality score (MIF) was higher in the group of non-frail elderly (122.1 points) compared to pre-frail (120.6 points) and frail (114.2 points). As for the FIM task "urine control", a high frequency of completely dependent frail elderly (n=9; 26.4%) and moderately dependent pre-frail (n=52; 27.9%) was observed. For the "social interaction" task, there was a significant frequency of moderately dependent frail elderly was observed (n=12; 35.3%). For the "problem solving" task, the same frequency (n=7; 20.6%) of completely dependent and moderately dependent frail elderly individuals was observed. In the evaluation of the "memory" task, the moderately dependent pre-frail stood out (n=26; 14%). The correlation between functionality (MIF) and HGS was weak, positive, and significant among the elderly in the investigated sample (Pˆ= 0.330; p=<0.001), among the nonfrail (Pˆ=0.252; p=<0.001) and among the elderly. pre-fragile (Pˆ= 0.236; p=0.001). The performance in the tasks "urine control" and "going up and down stairs" was significantly correlated with HGS (p=<0.005) among the pre-frail elderly. The tasks "urine control" for the non-frail elderly (Pˆ=0.309) and "going up and down stairs" for the pre-frail stand out, with the highest correlation coefficient with HGS (Pˆ=0.222). The "problem solving" task was correlated with HGS among pre-frail (p=<0.004) and frail (p=<0.017) elderly, with the highest correlation coefficient (Pˆ=0.408) among these. There is also a correlation between the task "verbal and non-verbal expression" and HGS for the frail elderly group (p=<0.025; Pˆ=0.383). It was concluded that there was a positive correlation between functionality and HGS among the non-frail and pre-frail elderly, indicating that the higher the HGS, the better the functional performance. Significant results for the clinical practice of gerontological nursing stand out, which can support preventive strategies aimed at maintaining HGS and functionality, especially among non-frail and pre-frail elderly people.

ABSTRACT

@#Introduction: Handgrip strength is a crucial biomarker of aging. Poor handgrip strength among hospitalized elderly increases the risk of health complications leading to a higher risk of hospital readmissions and mortality. This study aimed to determine handgrip strength among hospitalized elderly in Klang Valley hospitals alongside its associated factors. Methods: A total of 57 subjects were recruited for this study. Face-to-face interviews and physical assessments were conducted to obtain data on sociodemographic factors, medical background, anthropometry assessments and biochemical markers level. Dietary intake was obtained through two days of 24-hour dietary recall while tools such as Global Oral Health Assessment Index (GOHAI) and Mini Nutrition Assessment- Short Form (MNA-SF) were used to assess perception towards oral health and malnutrition risk, respectively. Reference value from the Asian Working Group of Sarcopenia (2014) was used to compare handgrip strength. Results: 94.7% of the subjects were found to have low handgrip strength with a mean value of 8.28 + 6.92 kg/force. Factors including age (r=- 0.370, p=0.005), educational level (r=0.471, p=<0.0005), perception towards oral health (r=0.370, p=0.005) and energy intake (r=0.367, p=0.005) were significantly associated with handgrip strength. Meanwhile, other variables were not significantly associated. Conclusion: The majority of the subjects had poor handgrip strength. Factors such as age, educational level, perception towards oral health and energy intake were significantly associated with handgrip strength while the rest were non-significantly associated. Thus, more research and intervention strategies should be done to improve handgrip strength among hospitalized elderly to achieve a healthy aging nation.

ABSTRACT

As a screening tool for detecting latent pre-locomotive syndrome (latent pre-LS) in women over the age of 40, measuring handgrip strength with a cut-off value of 26 kg was proposed in a previous report. However, this screening method missed 22% of latent pre-LS. It would be beneficial to screen almost persons with latent pre-LS in community pharmacies. In this study, it was investigated whether screening using the combination of measuring handgrip strength and the questionnaire, “Loco-check,” which was proposed by the Japanese Orthopaedic Association, improved the detection of latent pre-LS in the same group mentioned above. Combining only one of the “Loco-check” questions, “I cannot put on a pair of socks while standing on one leg,” with the measurement of handgrip strength with the cut-off value of 26 kg, the detection of latent pre-LS was increased to 90.2%. The odds ratio was 9.72 in logistic regression analysis. Using the combination of the measurement of handgrip strength and the response to one question is both rapid and convenient. Therefore, in this study, this screening combination is proposed to be a useful tool in community pharmacies for detecting early latent pre-LS.

ABSTRACT

Objective:The aim of this study was to explore the associations of muscle size and density with handgrip strength(HGS)and the Timed Up and Go(TUG)test.Methods:Totally 301 participants living in the Xinjiekou community near Beijing Jishuitan Hospital were recruited for CT imaging of the hip and a 1-cm slice of the mid-thigh.The cross-sectional area and density of the gluteus maximus and the mid-thigh muscles were estimated by the Osirix viewer based on CT images.HGS and TUG were also performed in these subjects.Logistic regression analysis was used to evaluate the correlations of muscle density and size with TUG and grip strength.Results:In women, after adjustment for age and BMI, the density of the gluteus maximus was negatively correlated with TUG( P trend=0.0366), while the size of the gluteus maximus and the mid-thigh muscles was not correlated with TUG.In men, the density or size of these muscles was not correlated with TUG.After adjustment for age and BMI, the density of the gluteus maximus was positively correlated with grip strength( P trend=0.0334)and the size of the mid-thigh muscles was also positively correlated with grip strength( P trend=0.0155)in men, but they were not correlated with grip strength in women. Conclusions:There were sex differences in the relationship between muscle size or density and grip strength or timed up and go.The density of the gluteus maximus is associated with muscle strength and physical performance while the size of the mid-thigh muscles is correlated with muscle strength.

ABSTRACT

Abstract Objective To describe postural balance, handgrip strength and mobility in children and adolescents with different types of osteogenesis imperfecta. Methods Cross-sectional study. Fifty selected subjects diagnosed with types I (n = 11), III (n = 21), and IV (n = 18), followed up at Brazilian reference center for osteogenesis imperfecta in the Midwest region, aged 2-21 years (9.2 ± 5.0), were enrolled in this study. Children and adolescents were evaluated for postural balance in the upright position with eyes-open and eyes-closed conditions, handgrip strength and the mobility domain (Pediatric Dysfunction Assessment Inventory). Data normality and difference between groups was verified. Results Handgrip strength was significantly lower in people with type III of osteogenesis imperfecta when compared to the osteogenesis imperfecta types I and IV, and to the age-specific reference data. Center of pressure length and mean velocity in the condition with eyes closed were worse compared to the open-eyes condition for children and adolescents with type I of osteogenesis imperfecta. There were worse results in the mobility domain for the participants classified with the most severe type of osteogenesis imperfecta. Conclusions It was observed that the severity of the osteogenesis imperfecta disease affected handgrip strength and locomotor function assessed by the mobility domain. Comparing osteogenesis imperfecta types, the higher the severity of osteogenesis imperfecta, the lower the handgrip strength. These results can contribute to new strategies of treatment focused on improving functional capacity and quality of life in people with osteogenesis imperfecta.

ABSTRACT

Abstract Aims: Motocross consists of two races of 30 min with a break in between. Recovery between races is paramount to performance, this study aimed to compare the effects of active and passive recovery between motocross races on riding performance. Methods: Thirteen elite and non-elite racers performed two races of 30 min with 1 h break, twice with two-week interval. Between the races active (20 min ergometer cycling at 60% of HRmax) or passive recovery (no activity) were executed in a randomized order. Lap times, heart rate during riding, blood lactate, reaction time, handgrip strength, upper back pull strength, counter movement jump height, and medicine ball throw distance were measured before and after both races. Serum creatine kinase enzyme activity and strength tests were assessed also 24 h after the races. Results: No statistically significant differences were observed in any variables between protocols. A significant drop in handgrip strength was found post-race values (p < 0.001). Post-racing creatine kinase values were above resting levels. Conclusion: These results do not support the use of active recovery in between motocross races for restoration of neuromuscular or riding performance. Motocross seems to cause some exercise-induced muscle damage; thus, some rest is required to recover homeostasis.

ABSTRACT

Abstract Objective The present study aimed to investigate the physical performance of handgrip strength (HGS) in women with polycystic ovary syndrome (PCOS). Methods A case-control study that included 70 women with PCOS and 93 agematched healthy women aged between 18 and 47 years with body mass index (BMI) between 18 Kg/m2-39.9 Kg/m2. The serum levels of total testosterone, androstenedione, insulin, estradiol, thyroid-stimulating hormone (TSH), prolactin, sex hormonebinding globulin (SHBG), and 17-hydroxyprogesterone (17-OHP) were measured. The free androgen index (FAI) and the homeostatic model assessment of insulin resistance (HOMA-IR) were calculated. The body composition regions of interest (ROIs) were assessed by dual-energy X-ray absorptiometry (DXA), and the handgrip strength (HGS) was evaluated for both the dominant and the non-dominant hands with a manual Sammons Preston (Bolingbrook, IL, US) bulb dynamometer. Results Women with PCOS had high serum levels of total testosterone (p < 0.01), androstenedione (p = 0.03), and insulin (p < 0.01), as well as high FAI (p < 0.01) and HOMA-IR (p = 0.01) scores. Compared with the non-PCOS group, the PCOS group had greater total lean mass in the dominant hand (p < 0.03) and greater HGS in both the dominant and the non-dominant hands (p < 0.01). The HGS was correlated with lean mass (p < 0.01). Conclusion Women with PCOS have greater HGS. This may be associated with age and BMI, and it may be related to lean mass. In addition, the dominance effect on muscle mass may influence the physical performance regarding HGS in women with PCOS.


Resumo Objetivo O objetivo deste estudo foi avaliar a força de preensão manual (FPM) em mulheres com síndrome dos ovários policísticos (SOP). Métodos Estudo de caso-controle que incluiu 70 mulheres com SOP e 93 mulheres saudáveis comidade entre 18 e 47 anos e índice demassa corporal (IMC) de 18 Kg/m2 a 39.9 Kg/m2. Foram dosados os níveis séricos de testosterona total, androstenediona, insulina, estradiol, hormônio estimulador da tireoide (HET), prolactina, globulina de ligação ao hormônio sexual (GLHS), e 17-hidroxiprogesterona (17-OHP). Foram calculados o índice de androgênio livre (IAL) e a avaliação do modelo homeostático da resistência à insulina (AMH-RI). As regiões de interesse (RIs) da composição corporal foram avaliadas por absorciometria de raios-x de dupla energia (ARDE), e a força de preensão manual (FPM) das mãos dominante e não dominante foi avaliada com um dinamômetro manual Sammons Preston (Bolingbrook, IL, EUA). Resultados Mulheres com SOP apresentaram níveis séricos elevados de testosterona total (p < 0.01), androstenediona (p = 0.03), e insulina (P < 0.01), assim como valores altos no IAL (p < 0.01) e no AMH-RI (p = 0.01). Comparado ao grupo controle, o grupo SOP apresentou maior massa magra total na mão dominante (p < 0.03) e maior FPM emambas asmãos (p < 0.01). A FPM foi correlacionada coma massamuscularmagra (p <0.01). Conclusão Mulheres com SOP têm maior FPM, que pode estar associada à idade, ao IMC, e à massa magra. Além disso, o efeito de dominância na massa muscular pode influenciar o desempenho físico na força de preensão manual em mulheres com SOP.

ABSTRACT

Objetivo. Analizar la asociación entre la fuerza de prensión manual relativa (FPMR) y la masa grasa (MG), controlando el posible efecto del estado de madurez.Metodología. Se estudiaron niños y adolescentes de ambos sexos con un rango de edad de ≥ 7,5 a ≤ 15,49 años. Se evaluó la FPMR mediante un dinamómetro hidráulico manual. El porcentaje de MG se evaluó mediante la absorciometría de rayos X de doble energía. Para analizar las diferencias por sexo y grupo etario y entre los niños normopesos y obesos en los niveles de FPMR, se utilizó el análisis de covarianza. Se consideraron como covariable los años de pico de velocidad de crecimiento (estado de madurez). Para analizar la asociación entre los niveles de FPMR y MG, se utilizó la correlación parcial, controlando el año de pico de velocidad de crecimiento.Resultados. Participaron 1685 escolares (731 mujeres y 954 varones). Fueron conformados 4 grupos de edad (7,5-9,4 años; 9,5-11,4 años; 11,5-13,4 años y 13,5-15,4 años). La FPMR aumentó con la edad en ambos sexos. Los valores de MG fueron elevados en todos los grupos etarios. No hubo diferencias en los grupos 3 y 4 en las niñas y en el grupo 4 de los niños. Los niños clasificados como peso normal presentaron significativamente mayor FPMR que los obesos. Se observó una asociación negativa entre FPMR y MG.Conclusión. Se demostró que la FPMR estaba negativamente asociada con la MG, tras controlar el efecto del estado de madurez


Objective. To analyze the association between relative handgrip strength (RHGS) and fat mass (FM) after controlling for the potential effect of maturity status.Methodology. Both male and female children and adolescents aged ≥ 7.5 to ≤ 15.49 years were studied. RHGS was assessed using a hydraulic hand dynamometer. FM percentage was established using a dual-energy X-ray absorptiometry. Age and sex differences in RHGS levels between normal weight and obese participants were studied with an analysis of covariance. A covariate was years from peak height velocity (maturity status). The association between RHGS and FM levels was analyzed using a partial correlation and controlling for age at peak height velocity.Results. A total of 1685 students (731 girls and 954 boys) participated. Four age groups were established (7.5-9.4 years, 9.5-11.4 years, 11.5-13.4 years, and 13.5-15.4 years). RHGS increased with age in both males and females. FM values were high in all age groups. No differences were observed in groups 3 and 4 among girls or in group 4 among boys. Participants classified as normal weight showed a significantly higher RHGS than their obese peers. A negative association was noted between RHGS and FM.Conclusion. RHGS was shown to be negatively associated with FM after controlling for the effect of maturity status
