Abstract
BACKGROUND Little is known about the prevalence, predictors and gender differences in hand grip strength of older adults in Africa. This study aims to investigate social and health differences in hand grip strength among older adults in a national probability sample of older South Africans who participated in the Study of Global Ageing and Adults Health (SAGE wave 1) in 2008. METHODS We conducted a national population-based cross-sectional study with a sample of 3840 men and women aged 50 years or older in South Africa. The questionnaire included socio-demographic characteristics, health variables, and anthropometric measurements. Linear multivariate regression analysis was performed to assess the association of social factors, health variables and grip strength. RESULTS The mean overall hand grip strength was 37.9 kgs for men (mean age 61.1 years, SD = 9.1) and 31.5 kgs for women (mean age 62.0 years, SD = 9.7). In multivariate analysis among men, greater height, not being underweight and lower functional disability was associated with greater grip strength, and among women, greater height, better cognitive functioning, and lower functional disability were associated with greater grip strength. CONCLUSIONS Greater height and lower functional disability were found for both older South African men and women to be significantly associated with grip strength.

Abstract
BACKGROUND Handgrip strength (HGS) is a marker of nutrition status. Many factors are associated with HGS. Age, height, body mass index, number of diagnoses, and number and type of drugs have been shown to modify the association between undernutrition and HGS. Nevertheless, other patient characteristics that could modify this association and its joint modifier effect have not been studied yet. OBJECTIVE To evaluate the association of inpatients' HGS and undernutrition considering the potential modifier effect of cognitive status, functional activity, disease severity, anthropometrics, and other patient characteristics on HGS. METHODS A cross-sectional study was conducted in a university hospital. Sex, age, abbreviated mental test score, functional activity score, Charlson index, number of drugs, Patient-Generated Subjective Global Assessment (PG-SGA) score, body weight, mid-arm muscle circumference, adductor pollicis muscle thickness, body height, wrist circumference, hand length, and palm width were included in a linear regression model to identify independent factors associated with HGS (dependent variable). RESULTS The study sample was composed of 688 inpatients (18-91 years old). All variables included in the model were associated with HGS (β, -0.16 to 0.38; P ≤ .049) and explained 68.5% of HGS. Age, functional activity decline, Charlson index, number of drugs, PG-SGA score, body weight, and wrist circumference had a negative association with HGS. All other studied variables were positively associated with HGS. CONCLUSION Nutrition status evaluated by PG-SGA was still associated with HGS after considering the joint effect of other patient characteristics, which reinforces the value of HGS as an indicator of undernutrition.

Abstract
Handgrip strength is useful for screening the nutritional status of adult population as it is strongly associated with physical disabilities and mortality. Therefore, we aimed to determine the predictors of handgrip strength among adults of a rural community in Malaysia using a cross-sectional study design with multistage sampling. All adults aged 30 years and older from 1250 households were invited to our study. Structured questionnaire on sociodemographic characteristics, medical history, occupation history, lifestyle practices, and measurements, including anthropometry and handgrip strength were taken. There were 2199 respondents with 55.2% females and majority were of Malay ethnicity. Their mean (standard deviation) age was 53.4 (13.2) years. The response rate for handgrip strength was 94.2%. Females had significantly lower handgrip strength than males ( P < .05). In the multiple linear regression models, significant predictors of handgrip strength for males were age, height, job groups, and diabetes, while for females, the significant predictors were age, weight, height, and diabetes.

Abstract
BACKGROUND & AIMS Metabolic disorders and malnutrition are well known conditions reported in patients with liver disease (LD), but the relationship between them are underexplored. So, the aim of this study was to assess the resting energy expenditure (REE) of these patients, identifying the prevalence of hyper- and hypometabolism. In addition, to evaluate whether malnutrition and clinical variables were associated with REE and metabolic disorders. METHODS The REE was measured by indirect calorimetry and predicted by the Harris and Benedict formula (REEHB). Nutritional status was assessed by different methods. The etiology, severity and complications of LD were also evaluated. RESULTS A total of 81 patients were assessed. The measured REE was 1587.5 ± 426.6 kcal. The REE was overestimated by the REEHB (REE:REEHB <0.8) in 7.4% and underestimated (REE:REEHB >1.2) in 24.7% of the patients. The REE was lower in malnourished patients (p < 0.05). However, hyper- and hypometabolism were not associated with nutritional status (p > 0.05). The REE and hypermetabolism were not associated with LD, but hypometabolic patients had a higher prevalence of Child C, and had higher values for MELD, INR and total bilirubin (p < 0.05). After multiple regression analyses, the REE was significantly associated (p < 0.05) with intracellular body water, arm muscle area and serum glucose. Serum glucose was only significantly associated (p < 0.05) with hypermetabolism, and INR with hypometabolism. CONCLUSION Changes in resting metabolism are present but not universal. The hypermetabolism was associated with extrahepatic factors, and hypometabolism with the severity of LD. Under these conditions in the clinical setting, calculated energy requirements using the HB formula should be adjusted.

Abstract
A relationship between weight loss and inflammation has been described in patients with cancer. In the present study, the relationship between subjective global assessment (SGA) and the severity of inflammation, as defined by Glasgow prognostic score (GPS), as well as the relationship of both of these measures with the presence of complications and survival time, was assessed. In addition, we compared the diagnosis given by SGA with parameters of nutritional assessment, such as body mass index, triceps skinfold, midarm circumference (MAC), midarm muscle circumference (MAMC), phase angle (PA), adductor pollicis muscle thickness (APMT), and handgrip strength (HGS). According to the SGA, the nutritional status was associated with the GPS (P < 0.05), and both the SGA and GPS were associated with the presence of complications. However, the GPS [area under the curve (AUC): 0.77, P < 0.05, confidence interval (CI) = 0.580, 0.956] seems to be more accurate in identifying complications than the SGA (AUC: 0.679, P < 0.05, CI = 0.426, 0.931). Only GPS was associated with survival time. Comparing the different nutritional assessment methods with the SGA suggested that the MAC, MAMC, APMT, PA, and HGS parameters may be helpful in differentiating between nourished and malnourished patients, if new cutoffs are adopted.

Abstract
Muscle strength, an independent predictor of metabolic disorders, disability, and mortality, reduces gradually with advancing age. Little is known about the influence of nutritional intervention on muscle strength in middle-aged. The aim of the present study is to examine whether magnesium could improve body composition and muscle strength in middle-aged overweight women. In this double-blinded, placebo-controlled, randomized trial, a total of 74 healthy middle-aged overweight women (25 ≤ BMI ≤ 30 kg/m(2)) received either 250 mg magnesium in the form of magnesium oxide or placebo daily for 8 weeks. Body composition was assessed using Bioelectrical Impedance Analysis (BIA). Handgrip strength and knee extension strength were measured with isometric dynamometry. Functional mobility was assessed using Time Get Up and Go Test (TGUG). A significant increase in mean lean body mass was observed (P = 0.05) accompanied with a significant decrease in fat mass (P = 0.02) solely in the magnesium group at the end of 8 weeks compared to baseline values but the changes did not reach significant as compared to placebo group. Handgrip strength and TGUG improved in the magnesium group compared to baseline but they were not significant compared to placebo. There were no significant differences in increasing knee extension strength in the magnesium group as compared with placebo. Baseline values of serum magnesium and muscle strength of participants did not indicate any influences on response to magnesium supplementation. Our findings indicate that magnesium as magnesium oxide, 250 mg/day, for 8 weeks do not lead to a significant greater gain in muscle strength and function compared to placebo.

Abstract
Malnourished patients with gastrointestinal tumours are at risk for postoperative complications and death. The aim of this study was to determine which nutritional assessment method better predicts outcome. Seventy-four patients, 45 men and 29 women; mean (SD) age of 63 (102) yr (range = 34 to 83), undergoing surgical resections for esophageal (n = 19) gastric (n = 43) and pancreatic (n = 12) tumors were preoperatively assessed by Patient Generated Subjective Global Assessment, anthropometry, and by laboratory sampling. Forty-three (58%) of them were unnourished; 25 Subjective Global Assessment (SGA)-A, 34 SGA-B, and 15 SGA-C cases. Mean (SD) of dominant hand adductor pollicis muscle thickness (DAPM) was 13 (3.5) mm and mean (SD) serum albumin was 3.8 (0.5) g/dL. Mean (SD) hospital staying for patients who complicated and died was 34 (29) days and 23 (13) days for survivors (not significant); SGA-B cases were significantly associated with higher mortality (n = 12, P<0.001). Patients with a mean (SD) DAPM below 10.8 (3.7) mm died more frequently than those with a mean (SD) greater than 14 (3) mm (P < 0.001). None of the methods was significantly related to hospital stay, but receiver operating characteristic curves (95% confidence interval) for PG-SGA and DAPM thickness (0.75 and 0.74) reliably predicted mortality (P<0.001) and these methods may be used as preoperative parameter.

Abstract
The handgrip strength is considered an excellent predictor of morbidity and mortality for acute and long term outcomes. In fact, several studies showed that the reduced handgrip strength is correlated to all-cause mortality in both middle aged and elderly subjects. Nevertheless, defined reference values of handgrip strength are not available, especially from young and healthy populations. The aim of this study was to determine the reference values for handgrip strength from a healthy population of young volunteers. A secondary objective was to derivate a muscle function T score useful for adults and elderly individuals. We enrolled 335 healthy university students (157 men and 178 females) aged 19-25 years. The handgrip strength was measured using a hydraulic hand dynamometer by trained dietitians. The mean handgrip strength value was 27.70 ± 4.3 kg for female and 44.77 ± 6.6 kg for male. We showed statistical difference between sexes. We also found the lower T score in community-dwelling elderly individuals in comparison to the young people. The muscle strength loss is a multi-factorial process influenced by age and hormonal factors. The availability of the reference values in both sexes might open the way to the diffusion of the handgrip strength assessment for more clinical use, and it might be useful to identify people who could benefit from early nutritional or pharmacological programs.

Abstract
Objectives Grip strength has been used as a measure of function in various health-related conditions. Although grip strength is known to be affected by both physical and psychological factors, few studies have looked at those factors comprehensively in a population-based cohort regarding elderly Koreans. The aim of this study was to evaluate potential factors influencing grip strength in elderly Koreans. Methods We evaluated dominant hand grip strengths in 143 men and 123 women older than 65 years who participated in a population-based cohort study, the Korean Longitudinal Study on Health and Aging (KLoSHA). Individuals who had a history of surgery for musculoskeletal disease or trauma in the upper extremity were excluded. Factors assessed for potential association with grip strength were; 1) demographics such as age and gender, 2) body constructs such as height, body mass index (BMI), and bone mineral density (BMD), 3) upper extremity functional status using disabilities of the arm, shoulder and hand (DASH) scores, and 4) mental health status using a depression scale and the short form-36 (SF36) mental health score. Multivariate analyses were performed in order to identify factors independently associated with grip strength. Results Grip strengths of dominant hands in elderly Koreans were found to generally decrease with aging, and were significantly different between men and women, as expected. Multivariate analyses indicated that grip strength was independently associated with age, height and BMI in men (R2 = 21.3%), and age and height (R2 = 19.7%) in women. BMD, upper extremity functional status, or mental health status were not found to be associated with grip strength. Conclusions This study demonstrates that in elderly Koreans, grip strength is mainly influenced by age and height in both men and women, and additionally by BMI in men. BMD or self-reported physical or mental health status was not found to influence grip strength in elderly Koreans. This information may be helpful in future studies using grip strength as a measure of function in elderly Koreans.

Abstract
BACKGROUND Reduced muscle strength is a cardinal feature in cachexia. We investigated whether weight loss is associated differently with muscle strength in men and women in a large cohort of hospitalized patients. METHODS One thousand five hundred hospitalized patients (whereof 718 men, mean age 57.6 ± 16.0 years, mean body mass index (BMI) 24.6 ± 4.8 kg/m²) were included in the study. Non-edematous involuntary weight loss was determined with Subjective Global Assessment; isometric maximal muscle strength was evaluated by hand grip strength. Mid-upper arm circumference and triceps skinfold were used to calculate arm muscle area. Interrelationship between sex and weight loss was evaluated by regression analysis performed with the general linear model (GLM) allowing adjustment for continuous and categorical variables and corrected for age, arm muscle area (AMA), BMI, and diagnosis category (benign/malignant disease) as potentially confounding covariates. RESULTS Both men and women exhibited a significant stepwise decrease of hand grip strength with increasing weight loss. Age, sex, moderate and severe weight loss, BMI, and AMA were significant predictors of hand grip strength. The GLM moreover revealed a significant sex × weight loss effect, since grip strength was similarly decreased in moderate weight loss in men and women when compared to control patients without weight loss (8.5% in men and 10.5% in women, not significant (n.s.)), but the further reduction of grip strength in severe weight loss was significantly different between men and women (10.6% vs. 4.1%, P = 0.033). CONCLUSIONS Our findings indicate sex-specific differences in muscle strength response to weight loss.

Abstract
OBJETIVO: Este estudo teve como objetivo avaliar a associação do estado nutricional com a força muscular de preensão manual e a densidade mineral óssea em idosos do sexo masculino. MÉTODOS: Participaram do estudo 41 idosos do sexo masculino, sendo 20 eutróficos (peso: M=69,6, DP=8,4; índice de massa corporal: M=25,7, DP=2,2) e 21 desnutridos (peso: M=50,9, DP=6,1; índice de massa corporal: M=18,7, DP=1,8), classificados subjetivamente segundo a Mini Avaliação Nutricional. A avaliação antropométrica incluiu peso corporal, altura, circunferência do braço e da panturrilha. A composição corporal foi avaliada pelo método de absorciometria por dupla emissão de Raios X, e a ocorrência de osteoporose foi definida de acordo com os critérios estabelecidos pela Organização Mundial da Saúde. A força muscular foi avaliada pelo dinamômetro de mão. RESULTADOS: O grupo desnutrido apresentou valores expressivamente menores dos parâmetros antropométricos e de com-posição corporal em relação ao grupo eutrófico (p<0,005). Além disso, a ocorrência de osteoporose foi signifi-cativamente maior (p<0,01) no grupo desnutrido em todas as regiões estudadas: colo do fêmur, quadril total e coluna. A força muscular de preensão manual dos idosos desnutridos foi significativamente menor que a dos idosos eutróficos (M=23,1, DP=6,8 e M=30,3, DP=8,4, respectivamente; p<0,005). CONCLUSÃO: A desnutrição está associada à menor força muscular e à diminuição da densidade mineral óssea em idosos do sexo masculino.

INTRODUCTION Protein-calorie malnutrition is a prevalent disorder in chronic renal failure (CRF) and a major risk factor for increased mortality in hemodialysis (HD) patients. Although many methods have been used to assess malnutrition in CRF, the role of adductor pollicis muscle thickness (APMt) is not established yet. AIMS This study aimed to analyze the APMt in HD patients and to investigate the correlation between APMt and conventional anthropometric, laboratory, and bioelectrical impedance markers, as well as its association with mortality/morbidity in a period of 12 months of follow-up. SUBJECTS AND METHODS The study included 143 HD patients from a single facility. After dialysis, the dry weight, height, mid-arm circumference, triceps skinfold thickness, and APMt were measured. Subsequently, the body mass index, percentage of standard body weight, the mid-arm muscle circumference, and the mid-arm muscle area were calculated. Blood counts were performed for hemoglobin, creatinine, and albumin. Patients were also submitted to a single-frequency tetrapolar bioimpedance test for measuring resistance, reactance, phase angle, and percentage of body cell mass. The correlation between APMt and anthropometric, laboratory, and bioelectrical impedance parameters was calculated using Pearson's linear correlation. Multiple linear regression analysis was used to select independent risk factors to death and hospitalizations in 6 and 12 months of follow-up, among parameters selected by univariate analysis. RESULTS Patients were aged 52.2 ± 16.6 years (20 to 83 years) on average, 58% were men, and mean dialysis vintage was 5.27 ± 5.12 years. APMt was 11.85 ± 1.63 mm (men, 12.34 ± 1.53; women, 11.19 ± 1.51; P < .0001). APMt was positively correlated with body mass index (r = 0.37; P < .0001), mid-arm circumference (r = 0.437; P < .0001), mid-arm muscle circumference (r = 0.494; P < .0001), mid-arm muscle area (r = 0.449; P < .0001), percentage of standard body weight (r = 0.355; P = .000), creatinine (r = 0.230; P = .006), albumin (r = 0.207; P = .013), percentage of body cell mass (r = 0.293; P = .000), and phase angle (r = 0.402; P < .0001), and negatively correlated with resistance (r = -0.403; P < .0001). The APMt ≤10.6 mm was associated with a 3.3 times greater risk of hospitalization within 6 months of follow-up (OR = 3.3, 95% CI: 1.13 to 9.66; P = .029) compared with patients with an APMt >10.6 mm. The APMt was not associated with risk of death at 6 and 12 months or hospitalization within 12 months of follow-up. CONCLUSION This is the first study testing APMt as an anthropometric marker in HD patients. The parameter is easy to measure and does not seem to be significantly affected by variations in hydration status. The parameter was significantly correlated with markers reflecting the condition of the muscle compartment, but not with parameters estimating the fat mass. The determination of an APMt cutoff point for malnutrition in patients with CRF and its correlation with morbidity and mortality will require further investigation in clinical studies.

Abstract
OBJECTIVE To examine the association between pain and functional capacity levels. DESIGN [corrected] Cross-sectional study. SETTING University of Granada. SUBJECTS One hundred twenty-three women with fibromyalgia (51.7 ± 7.2 years). OUTCOME MEASURES We measured weight and height, and body mass index (BMI) was calculated. We assessed tender points by pressure pain and functional capacity by means of the 30-second chair stand, handgrip strength, chair sit and reach, back scratch, blind flamingo, 8-ft up and go and 6-minute walk tests. RESULTS We observed an association of tender points count with the chair stand and 6-minute walk tests (r = -0.273, P = 0.004 and r = -0.183, P = 0.046, respectively). These associations became nonsignificant once the analyses were adjusted by weight or BMI. We observed an association of algometer score with the back scratch, chair stand, and 6-minute walk tests (r = 0.238, P = 0.009; r = 0.363, P < 0.001; and r = 0.186, P = 0.043, respectively), which remained after adjusting for weight or BMI, except the association between algometer score and the 6-minute walk test that became nonsignificant once the analyses were adjusted by weight. Prevalence of overweight and obesity was 39.2 and 33.3%, respectively. CONCLUSIONS There is an inverse association of tender points count with the chair stand and distance walked in the 6-minute walk tests, and a positive association of algometer score with the chair stand, distance walked in the 6-minute walk and back scratch tests, yet, weight status seems to play a role in these associations.

Abstract
Existe uma grande variedade de instrumentos utilizados para a avaliação da força de preensão manual. Porém, não existem estudos demonstrando a validade e a confiabilidade da maioria destes instrumentos. O objetivo deste estudo foi avaliar a validade concorrente e a confiabilidade intraexaminador do dinamômetro Saehan hidráulico comparado-o com o dinamômetro Jamar hidráulico. Cem indivíduos sadios (50 homens e 50 mulheres), entre 20 e 50 anos de idade, sem alterações cognitivas, deficiências físicas, disfunções neuromusculares e ortopédicas e história de lesões nos membros superiores, foram testados com os dinamômetros Jamar e Saehan. A validade concorrente entre o dinamômetro Jamar e o dinamômetro Saehan foi excelente para os testes de força de preensão realizados com as mãos direita (r=0,976) e esquerda (r=0,986). A confiabilidade intra-examinador foi excelente tanto para o dinamômetro Jamar (r=0,985 mãos direita e esquerda) quanto para o dinamômetro Saehan (r=0,981 mão direita e r=0,985 mão esquerda). O dinamômetro Saehan é válido, confiável e comparável com o dinamômetro Jamar. Portanto, dados coletados com o dinamômetro Jamar são equivalentes aos dados coletados com o dinamômetro Saehan. Consequentemente, valores de força obtidos por testes com dinamômetro Saehan podem ser comparados com valores de referência de força de preensão que foram obtidos com o dinamômetro Jamar.

Abstract
BACKGROUND & AIMS Among all muscle function tests, measurement of hand grip strength has gained attention as a simple, non-invasive marker of muscle strength of upper extremities, well suitable for clinical use. This review outlines the prognostic relevance of grip strength in various clinical and epidemiologic settings and investigates its suitability as marker of nutritional status in cross-sectional as well as intervention studies. METHODS Studies investigating grip strength as prognostic marker or nutritional parameter in cross-sectional or intervention studies were summarized. RESULTS AND CONCLUSIONS Numerous clinical and epidemiological studies have shown the predictive potential of hand grip strength regarding short and long-term mortality and morbidity. In patients, impaired grip strength is an indicator of increased postoperative complications, increased length of hospitalization, higher rehospitalisation rate and decreased physical status. In elderly in particular, loss of grip strength implies loss of independence. Epidemiological studies have moreover demonstrated that low grip strength in healthy adults predicts increased risk of functional limitations and disability in higher age as well as all-cause mortality. As muscle function reacts early to nutritional deprivation, hand grip strength has also become a popular marker of nutritional status and is increasingly being employed as outcome variable in nutritional intervention studies.

Abstract
Hand grip strength is an inevitable component in the evaluation of rheumatoid arthritis, neuromuscular, preoperative, post operative patients and community dwelling older adults' functional capacity. Hand grip varies greatly with age, gender and the anthropometric measures when measured by hand dynamometer. The influence of above variables on hand grip when measured by modified sphygmomanometer is unknown. Further, the prediction of hand grip from age and anthropometric traits is unknown. 229 subjects (115 males and 114 females) with age 23 ± 2 and 21 ± 2 respectively were included in the study after informed c nsent. Weight and height were obtained using standard techniques. Hand grip was measured using a modified sphygmomanometer. Information regarding physical activity and health status was obtained by interview, clinical screening and stratified. Stepwise multiple regression analysis was sought out for any influence of age, height, weight and Body Mass Index (BMI) on hand grip strength. Grip strength correlated moderate to high with age (r = 0.44, p = 0.00), height (r = 0.57, p = 0.00), weight (r = 0.57, p = 0.00) and BMI (r = 0.29, p = 0.00). The regression model for handgrip strength is Hand grip = -1790.54 + 4.93557 × Age-11.7429 × Weight + 1083.4 × Height + 34.194 × BMI. Age, height and weight are the i portant determinants of the handgrip evaluation. In clinical setting, the influence of age and anthropo etric traits on handgrip shall be borne in mind when measuring handgrip by modified sphygmomanometer in age group of 20-25 year patients.

Abstract
With aging, the incidence of falls and fractures increases. There has during the last decades been secular changes in demographics so that the proportion of elderly increases in society. Hence, there is an increasing need for clinicians to be able to make a solid appraisal of the elderly patient's functional capacity, as to identify individuals with an increased risk to fall. If high risk individuals could be targeted fall preventive strategies might be implemented in specific risk cohorts. This would require reference values for muscle strength tests and functional tests, in order to defined high risk individuals performing inferior. From the MrOS Sweden cohort, 999 subjects aged 70-80 years were evaluated. Muscle strength and functional performance was tested by timed-stands test, 6-m and 20-cm narrow walk tests and Jamar handgrip strength test. Normative data is presented. With increasing age, there was a 10-18% successively decline in performance throughout the entire age span. This study provides reference values for handgrip strength and functional muscle tests in 70-80 years old men. The decline in the test values with increasing age, infer the use of age-specific normative data when using these tests both in clinical and research settings.

Abstract
OBJECTIVE Investigate whether the right adductor pollicis muscle thickness is a reliable method to evaluate the nutritional status of surgical patients and whether it correlates or not correlate to other anthropometric, biochemical, and clinical parameters. METHODS Cross-sectional study evaluating 87 patients candidates to major operations of the gastrointestinal tract. All were submitted to global subjective evaluation, traditional anthropometry (arm circumpherence ; triceps skin fold; and arm muscle circumpherence, serum albumin, lymphocytes and measurement of in both hands. RESULTS The mean right adductor pollicis muscle thickness in dominant hand was 12,64 +/- 3,19 mm and in non-dominant hand (EMAPND) 12,23 +/- 2,9 mm. Sensitivity was 72,37% for left adductor pollicis muscle and 77,33% for left adductor pollicis muscle thickness being the cut-offs given by the ROC curve (13,4 and 13,1mm respectively). Specificity was 100% for both hands. There was a significantly correlation (P<0.01) for right adductor pollicis muscle thickness with all anthropometric parameters. The mean value for normal individuals was significantly greater (P<0.001) than for mild malnourished which was greater (p<0.05) when compared to patients with severe malnutrition. CONCLUSION right adductor pollicis muscle thickness is a low-cost, reliable, and trustworthy method to assess nutritional status that can be easily and safety used in clinical practice for surgical patients.

Abstract
BACKGROUND Organised crime and political violence (OPV) and human rights violations have marred Bangladesh history since 1971. Little is known about the consequences for the oppressed population. This study describes the patterns of OPV and human rights violations in a disturbed area of Bangladesh and assesses the physical, emotional and social functioning of victims. METHODS A total of 236 of selected participants in a household survey in Meherpur district were recruited for a detailed study. Interviews and physical examinations were used to obtain information about history of torture and other cruel, inhuman or degrading treatment or punishment (TCIDTP), and about injuries, pain frequency and intensity. Handgrip strength and standing balance performance were measured. The "WHO-5 Well-being" scale was used to assess the subjective emotional well-being of study participants. RESULTS The majority of the reported cases of TCIDTP occurred in 2000-2008, 51% of incidents occurred during winter; 32.0% between 20:00 and midnight. Police involvement was reported in 75% of cases. Incidents took place at victims' homes (46.7%), or at the police station, military camp, in custody or in prison (21.9%). Participants experienced 1-10 TCIDTP methods and reported 0-6 injury locations on their bodies; 77.5% reported having at least two injuries. Less than half of the participants were able to stand on one leg for 30 seconds. Only 7.5% of males aged 25-44 had handgrip strength in both hands exceeding average values for healthy people at the same age. Over 85% of participants scored low (<13) on the 25-point "WHO-5 Well-being" scale. The number of years since the TCIDTP event, pain frequency, the need to quit a job to take care of an injured family member, political involvement, personal conflicts and the fear of neighbourhood violence strongly affected emotional well-being. Good emotional well-being correlated with increased political and social participation. CONCLUSION A detailed picture of characteristics of the victimisation is presented. The participants showed poor emotional well-being and reduced physical capacity. The results indicated that the simple and rapid method of assessment used here is a promising tool that could be used to monitor the quality and outcome of rehabilitation.

Abstract
O objetivo deste estudo foi avaliar os valores normais da força de preensão manual do membro superior dominante (FPM-D) e não dominante (FPM-ND) em sujeitos de meia idade e idosos assintomáticos e elaborar equações de referência para a predição da FPM. Foram investigados 54 voluntários (51,9% homens) com idade >50 anos, medindo-se massa corporal, estatura e perimetria do braço direito e esquerdo, e calculando-se o índice de massa corporal. A FPM-D e FPM -ND foram avaliadas por dinamometria mecânica. O índice de atividade física habitual (IAF) foi avaliado pelo questionário de Baecke. A FPM-D foi superior à FPM-ND em ambos os sexos e em todas as idades (p<0,05). Foram encontradas correlações significativas entre a FPM e idade, estatura, massa corporal e perimetria do braço. As melhores equações de referência foram as seguintes: FPM-Dkgf =39,996 - (0,382 x idade anos)+(0,174 x peso kg)+(13,628 x sexo homens=1;mulheres=0) (R²ajustado=0,677); e FPM-NDkgf=44,968- (0,420 x idade anos)+(0,110 x peso kg)+(9,274 x sexo homens=1;mulheres=0) (R²ajustado=0,546) A diferença consistente entre a FPM-D e FPM-ND torna necessário o uso de dados normativos específicos para cada mão. Atributos simples de serem obtidos, tais como idade, estatura, massa corporal, perimetria do braço e sexo, podem pois prever adequadamente os valores esperados da FPM para adultos e idosos assintomáticos.

Abstract
INTRODUCTION The impedance vector produced by an alternating current in the bioimpedance analysis can be seen as a standardised test of cellular mass and function since reactance is believed to reflect the mass and integrity of cell membranes. This study investigated the association between resistance and reactance normalised for height (R/H and Xc/H), and muscle function as assessed by hand grip strength. METHODS 363 patients (172 male, 191 female) from Berlin and Copenhagen were included in the analysis. Whole body impedance was determined by BIA 2000M (Berlin) or EFG2.0 (Copenhagen). Hand grip strength was measured with Digimax electronic hand dynamometer (Berlin) or Jamar dynamometer (Copenhagen). The general linear model was used to assess the association between R/H, Xc/H and hand grip strength. RESULTS We observed a significant association between the impedance parameters R/H and Xc/H and hand grip strength after adjusting for confounding variables (hand grip strength= -36.9 - 0.063 x R/H + 0.573 x Xc/H + 40.7 x Height + 0.115 x Weight - 0.09 x Age + 3.41 (gender=male) + 1.87 (Centre Berlin); Weight: P=0.04, all other coefficients: P<0.0005. r(2)=0.708). CONCLUSIONS The impedance parameters R/H and Xc/H are related to hand grip strength and might therefore be used as a cooperation-independent method to reproducibly assess muscle function.
