    Abstract: The use of skinfold thickness measurements to evaluate the distribution of subcutaneous adipose tissue and to predict body fat has recognised advantages. However, the different types of skinfold calliper available present limitations that make them unattractive and perhaps less used in daily practice. The purpose of the present study was to evaluate the accuracy and functionality of a new digital skinfold system, the Liposoft 2008+Adipsmeter V0 (LA), for measuring skinfold thickness and determining body fat proportion (%BF). Skinfold thickness measurements made by the LA were compared with those obtained with a Harpenden (H) calliper from two samples of adults ( n 45) and older adults ( n 56) in a university-based cross-sectional study. A comparison was also conducted between estimated %BF from skinfolds and dual-energy X-ray absorptiometry. Bland and Altman plots show that skinfolds measured by the LA and H calliper are in high agreement, with a mean difference of 0·3 (95 % CI − 3·1, 3·4) mm. In regard to the %BF estimated from LA and H skinfolds measurement, the LA produced a similar approximation to dual-energy X-ray absorptiometry %BF, with a mean difference of 0·2 (95 % CI − 0·8, 1·2) %, compared with %BF obtained with the H calliper. The LA system is an accurate instrumentation and represents an innovation in the evaluation of skinfold thickness and body composition based on anthropometric measurement.

    Abstract: To characterise the nutritional status and to identify malnutrition-associated variables of older adults living in Portuguese nursing homes. Design Cross-sectional study. Data on demographic and socio-economic characteristics, self-reported morbidity, eating-related problems, nutritional status, cognitive function, depression symptoms, loneliness feelings and functional status were collected by trained nutritionists through a computer-assisted face-to-face structured interview followed by standardised anthropometric measurements. Logistic regression was used to identify factors associated with being at risk of malnutrition/malnourished. Setting Portuguese nursing homes. Subjects Nationally representative sample of the Portuguese population aged 65 years or over living in nursing homes. Results A total of 1186 individuals (mean age 83·4 years; 72·8 % women) accepted to participate. According to the Mini Nutritional Assessment, 4·8 (95 % CI 3·2, 7·3) % were identified as malnourished and 38·7 (95 % CI 33·5, 44·2) % were at risk of malnutrition. These percentages increased with age and were significantly higher for women. Logistic regression showed (OR; 95 % CI) that older adults reporting no or little appetite (6·5; 2·7, 15·3), those revealing symptoms of depression (2·6; 1·6, 4·2) and those who were more dependent in their daily living activities (4·7; 2·0, 11·1) were also at higher odds of being malnourished or at risk of malnutrition. Conclusions Malnutrition and risk of malnutrition are prevalent among nursing home residents in Portugal. It is crucial to routinely screen for nutritional disorders, as well as risk factors such as symptoms of depression and lower functional status, to prevent and treat malnutrition.

    Abstract: Handgrip strength (HGS) is an indicator of muscle condition and general health wellbeing. Usually, instruments measuring handgrip strength only identify its maximum value. This preliminary study is focused on identifying force vs. time parameters which could contribute to better describe individual strength. They were obtained during a Handgrip strength test of 15 s in a sample group of 94 university students. The tests were conducted with a smart multifunction novel prototype dynamometer, named BodyGrip. Mean values of quantities related to the ability to develop and to maintain strength in percentage of maximum handgrip strength, were extracted from the force vs time profile. Contrary to maximum HGS, such quantities were found to be independent of the participant’s anthropometric characteristics. Individual comparisons based on those quantities are therefore not affected by the anthropometric characteristics. It was possible to identify individuals, differing on the development of HGS. Results suggest that the functionality of the BodyGrip tool enables a more thorough characterization of the time profile of the Handgrip strength that might influence the knowledge of the muscle functions, such as power development and endurance.

    Abstract: Sarcopenia is prevalent in heart failure (HF) patients, contributing to its poor prognosis. Statin use is postulated as a probable risk for developing sarcopenia, but little is known regarding this association in HF patients. This work aims at classifying and characterising sarcopenia and at describing the association of statin use with sarcopenia in a sample of Portuguese HF outpatients. Methods In this cross-sectional study, a sample of 136 HF patients (median age: 59 years, 33.8% women) was recruited from an HF outpatients’ clinic of a University Hospital in Portugal. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People 2. Clinical, nutritional, and dietary data were collected. Results A total of 25 (18.4%) individuals were categorised as sarcopenic, ranging from 12.2% in younger ( 〈  65 years) participants vs. 30.4% in older ones and from 3.3% in men vs. 47.8% in women. Severe sarcopenia accounted for 7.4% of the sample and sarcopenic obesity was identified in 5.1% of the individuals. A total of 65.4% of the participants were statin users. In multivariable analysis (n = 132, 25 sarcopenic), the use of statins was inversely associated with sarcopenia (OR = 0.03; 95% CI = 0.01, 0.30). Each additional age year was associated with a 9% increase in the likelihood of being sarcopenic (OR = 1.09; 95% CI = 1.01, 1.17), and each Kg.m −2 increment in body mass index was associated with a 21% decrease in the likelihood of sarcopenia (OR = 0.79; 95% CI = 0.65, 0.96). The daily use of five or more medicines was also directly associated with sarcopenia (OR = 26.87; 95% CI = 2.01, 359.26). On the other hand, being a man and being physically active were inversely associated with sarcopenia (OR = 0.01; 95% CI = 0.00, 0.07 and OR = 0.09; 95% CI = 0.01, 0.65, respectively). Conclusions Contrary to what was expected, patients medicated with statins were less likely to be sarcopenic. Although this finding deserves further research, we hypothesise that this might be related to the pleiotropic effects of statins on endothelial function, contributing to better neuromuscular fitness.

    Abstract: Guerra, RS, Amaral, TF, Sousa, AS, Fonseca, I, Pichel, F, and Restivo, MT. Comparison of Jamar and Bodygrip dynamometers for handgrip strength measurement. J Strength Cond Res 31(7): 1931–1940, 2017—Studies that compared the agreement between Jamar and other models of dynamometers for handgrip strength (HGS) measurement have exhibited variability in the provided results. The lack of comparability between dynamometers led to the development of the Bodygrip dynamometer. This study aims to examine the reliability of the Bodygrip for HGS measurement, to compare it with the Jamar, and to explore the HGS differences between instruments considering the ergonomic effect of using the Bodygrip with 2 different handles. A cross-sectional study was conducted in free-living ( n = 114, 18–89 years) and inpatient ( n = 50, 65–93 years) volunteers. Nondominant HGS was tested randomly with the Jamar and Bodygrip, the latter using 2 different handles—curved and straight types. Handgrip strength was obtained for each participant under the same conditions. Each individual performed 2 HGS measurements with each dynamometer, and the maximum HGS value was considered for dynamometers comparison. Differences in the maximum HGS value between the 2 devices (Jamar-Bodygrip), intraclass correlation coefficients (ICCs), Bland and Altman plots, and limits of agreement were obtained. Correlation between the highest HGS measurement obtained for the nondominant hand with the Jamar and with the Bodygrip using each handle was excellent (ICCs: 0.93–0.95). Mean differences of −0.5 (limits of agreement: −4.6; 3.5) kgf with the curved handle and of 1.0 (−7.7; 9.7) kgf with the straight handle for the free-living participants were obtained, whereas for inpatients these values were −1.0 (−3.8; 1.9) kgf and 2.1 (−3.3; 7.5) kgf, respectively, for the curved and straight handles. The Bodygrip is comparable to the Jamar in free-living adults and in hospitalized older adults, exhibiting excellent interinstrument reliability. The Bodygrip with the curved handle produces results closer to the Jamar when compared with Bodygrip with the straight handle, which emphasizes the importance of grip handle ergonomics to measurement reliability.

    Abstract: Background and Objective : Handgrip strength is a relevant marker of functional status and is also a component of nutrition assessment. The simplicity of this measurement supports its usefulness as a tool to predict who will likely take longer to hospital discharge. The aim of this study was to quantify the association between sex‐specific handgrip strength at hospital admission and time to discharge alive. We intended to include a group of diverse diagnoses and to compare medical and surgical wards, taking into account the potential confounders’ effect of patients’ characteristics and severity of disease. Subjects and Methods : Prospective study in 2 public acute‐care general hospitals in Porto, Portugal, in 2004. Handgrip strength was evaluated using a handgrip dynamometer in a probability sample of 425 patients from medical and surgical wards. The association between baseline handgrip strength and time to discharge was evaluated using survival analysis with discharge alive as the outcome and deaths and transfers being censored. Results: In medical wards, women with high admission handgrip strength had a very short hospital stay (all had been discharged by the sixth day), and among men, patients with low handgrip strength had a particularly longer stay (approximately 50% were discharged after 15 days of hospitalization). In surgical wards, an increasing length of stay with decreasing handgrip strength quartiles was also observed in both sexes. Conclusions : Lower handgrip strength at hospital admission was associated with a longer time in the hospital, in patients of both sexes, in medical and surgical wards. Although this association was explained in part by age, height, education level, cognitive status, and disease severity, its direction remained unchanged regardless of the aforementioned factors.

    Abstract: The association between nutritional status and gait speed remains unclear. This study described gait speed in older adults and quantified the association between overweight, obesity, undernutrition risk and gait speed. Gait speed as potential indicator of nutritional outcomes was also explored. A cross-sectional analysis was conducted in a population-based sample of 1,500 older adults ≥65 years old. Compared to “normal body mass index” women, odds ratio for a slow gait speed was approximately 2-fold higher in“overweight”, 4-fold higher in “obese” and 6-fold higher in women at “undernutrition risk”. “Undernutrition risk” category resulted from joining “undernutrition risk/undernutrition”. For men, these associations were in the same direction, but the odds ratio estimates halved. In women, identified gait speed cut-offs were 0.87 m/s for “obesity” and 0.79 m/s for “undernutrition risk”. In men, 0.94 m/s is the cut-off in which most older adults were correctly classified relative to “undernutrition risk”. About half of Portuguese older adults presented a gait speed ≤0.8 m/s. Overweight, obesity and undernutrition risk were directly and increasingly associated with slow gait speed, but approximately twice as high in women compared to men. Gait speed revealed potential utility in marking nutritional problems, but further investigation is recommended.

    Abstract: The burden of food insecurity in Portugal, and the socioeconomic and demographic factors that are related to this condition, are unknown. Objective To evaluate the frequency of food insecurity and to identify its associated characteristics in the Portuguese population. Methods Data from 3,552 heads of family respondents of the 2005/06 Portuguese National Health Survey were analyzed in a cross-sectional study. Food insecurity was evaluated with the use of the US Department of Agriculture Household Food Security Survey Module 6-Item Short Form. Chi-square tests and multivariate logistic regression models were conducted. Significance was indicated at p 〈 .05. Results Among the respondents, 16.5% were food insecure and 3.5% had very low food security. The odds of being food insecure were highest for women (OR, 1.51; 95% CI, 1.20 to 1.91), smokers (OR, 1.56; 95% CI, 1.20 to 2.02), younger people (OR, 2.54; 95% CI, 1.69 to 3.80), unemployed people (OR, 3.04; 95% CI, 2.01 to 4.60), those with lower education (OR, 7.98; 95% CI, 4.73 to 13.49), and those with lower income (OR, 6.27; 95% CI, 4.23 to 9.30). Conclusions The present study explored for the first time the burden of food insecurity in Portugal, revealing that it was highly prevalent, affecting one in six Portuguese citizens. Low education and low income were the main factors associated with food insecurity.

    Abstract: The aim of this study was to describe sarcopenia frequency, to identify the factors associated with sarcopenia and undernutrition, and to evaluate their coexistence. Methods A total of 1500 Portuguese older adults aged ≥65 years from the Nutrition UP 65 study were evaluated using a cross‐sectional analysis. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People (EWGSOP)2 guidelines (2018), using anthropometric measures. Undernutrition status was evaluated by Mini‐Nutritional Assessment‐Short Form. Results Sarcopenia frequency was 4.4% (n = 66). Sarcopenia coexists with undernutrition or undernutrition risk in 1.5% of this sample. In the multivariate analysis, sarcopenia was directly associated with age 〉 75 years (odds ratio (OR): 2.14; 95% confidence interval (CI): 1.19–3.84), undernutrition or undernutrition risk (OR: 1.86; 95% CI: 1.01–3.43) and inversely associated with male gender (OR: 0.52; 95% CI: 0.29–0.97), overweight (OR: 0.24; 95% CI: 0.13–0.42) or obesity (OR: 0.02; 95% CI: 0.01–0.09) and moderate alcohol consumption (OR: 0.47; 95% CI: 0.24–0.90). Undernutrition or undernutrition risk was associated with a poor or very poor self‐perception of health status (OR: 3.53; 95% CI: 2.32–5.37), a low physical activity level (OR: 1.74; 95% CI: 1.23–2.47), sarcopenia (OR: 1.85; 95% CI: 1.02–3.36), and being overweight (OR: 0.40; 95% CI: 0.27–0.59) or obese (OR: 0.43; 95% CI: 0.28–0.65). Conclusions The majority of the older adults presented low muscle strength (probable sarcopenia), but only a small number had concomitantly low muscle quantity or quality (sarcopenia). Coexistence between these conditions is low which reinforces the need to assess them both individually during geriatric assessment.
