Abstract The phase angle (AF) obtained by electrical bioimpedance (BIE) analyzes the muscle composition by establishing the amount of water and electrolytes as indicators of cell size, number, and integrity, as essential body composition axes to determine training objectives and states of Health. Objective To determine the relationship between AF and maximum force (FM) and explosive (FME) in soccer players from Bogotá-Colombia. Methods Cross-sectional study of correlational scope. 86 players were selected (age: 18.67 ± 2.9 years; height: 1.73 ± 0.070 m; weight: 66.58 ± 9.94 kg) team members: Fortaleza, Tigres, Juventus, and Dinhos. The following were evaluated: body composition using InBody® 770; FM using T-Force® and FME (SJ) with optogait®. Results AF 6,46 ±0,58, FM in squats 614,4N ±262,28, maximum squat power 326,34W ±182,16 and maximum jump power SJ 649,7W ±117. There was a statistically significant relationship between musculoskeletal mass (0.598 p = 0.000),% body fat mass (-0.458 p = 0.000), peak FM (0.639 p = 0.000), maximum peak power (0.569 p = 0.000), maximum jump power (-0.636 p = 0.000) and AF. AF is associated with variables of body composition and muscle strength, making it an instrument that could help predict physiological behavior in soccer players and the general population. It shows correlations and markers applicable to sports and clinical diagnosis that will allow generating health promotion programs. Key messages The AF is constituted as an easily accessible marker for nutritional health and functional profile in athletes. AF is associated with variables of body composition and muscle strength, making it an instrument that could help predict physiological behavior in soccer players and the general population.

Abstract In the present cross-sectional study of 403 independently living elderly men, we tested the hypothesis that the decreases in bone mass, body composition, and muscle strength with age are related to the fall in circulating endogenous testosterone (T) and estrogen concentrations. We compared various measures of the level of bioactive androgen and estrogen to which tissues are exposed. After exclusion of subjects with severe mobility problems and signs of dementia, 403 healthy men (age, 73–94 yr) were randomly selected from a population-based sample. Total T (TT), free T (FT), estrone (E1), estradiol (E2), and sex hormone-binding globulin (SHBG) were determined by RIA. Levels of non-SHBG-bound T (non-SHBG-T), FT (calc-FT), the TT/SHBG ratio, non-SHBG-bound E2, and free E2 were calculated. Physical characteristics of aging included muscle strength measured using dynamometry, total body bone mineral density (BMD), hip BMD, and body composition, including lean mass and fat mass, measured by dual-energy x-ray absorptiometry. In this population of healthy elderly men, calc-FT, non-SHBG-T, E1, and E2 (total, free, and non-SHBG bound) decreased significantly with age. T (total and non-SHBG-T) was positively related with muscle strength and total body BMD (for non-SHBG-T, respectively, β = 1.93 ± 0.52, P < 0.001 and β = 0.011 ± 0.002, P < 0.001). An inverse association existed between T and fat mass (β = −0.53 ± 0.15, P < 0.001). Non-SHBG-T and calc-FT were more strongly related to muscle strength, BMD, and fat mass than TT and were also significantly related to hip BMD. E1 and E2 were both positively, independently associated with BMD (for E2, β = 0.21 ± 0.08, P < 0.01). Non-SHBG-bound E2 was slightly strongly related to BMD than total E2. The positive relation between T and BMD was independent of E2. E1 and E2 were not related with muscle strength or body composition. In summary, bioavailable T, E1, total E2, and bioavailable E2 all decrease with age in healthy old men. In this cross-sectional study in healthy elderly men, non-SHBG-bound T seems to be the best parameter for serum levels of bioactive T, which seems to play a direct role in the various physiological changes that occur during aging. A positive relation with muscle strength and BMD and a negative relation with fat mass was found. In addition, both serum E1 and E2 seem to play a role in the age-related bone loss in elderly men, although the cross-sectional nature of the study precludes a definitive conclusion. Non-SHBG-bound E2 seems to be the best parameter of serum bioactive E2 in describing its positive relation with BMD.

Abstract Background and Aims Gait speed is a predictor of disability, mobility limitation and mortality. Buchner et al. the first to observe a non-linear relationship between leg strength and normal gait speed. This relationship was explained as small changes in physiological capacity. The objective of this study is to assess the relationship between gait speed and body composition in haemodialysis. Method Cross-sectional study in 40 subjects with CKD in hospital haemodialysis, 70.5±13.03 years, 62.5% male. 40% Diabetic Nephropathy, 10% Glomerulopathies, 7.5% Nephroangiosclerosis, 2.5% Chronic Tubule-Interstitial Nephropathies, 32.5% Unknown, 2.5% Others. 35% arteriovenous fistula, 10% arteriovenous graft, 55% central venous catheter. Haemodialysis type: 40% High Flux, 45% Online postdilutional Haemodiafiltration, 10% Acetate Free Biofiltration. Gait seed was measured on the middle day of the week, predialysis. Body composition was estimated by monofrecuency bioimpedance measurement (50 KHz) on the middle day of the week, posthemodiálisis. Statistical analysis was performed with SPSS 13.0. Results Average gait speed 0.6±0.38 m/s, median 0.65 (IQR 0.18) m/s, range (0, 1.23) m/s. The prevalence of a gait speed less than or equal to 0.8 m/s was 67.5%, while 32.5% of the patients presented a gait speed less than or equal to 0.8 m/s. Gait speed was lower among diabetics (0.77±0.3 vs 0.46±0.39, p=0.0074). A positive and significant correlation was observed between gait speed and phase angle. No correlation was observed between gait speed and body fat. A positive linear relationship or dependence was observed between gait speed and muscle mass and cell mass. In relation to body water, a negative linear relationship is observed with the EW/IW ratio. Table 1. Conclusion There is a dependent relationship between gait speed and diabetes in haemodialysis patients. The decrease of the phase angle, the increase of the ratio EW/IW changes with the decrease the cell mass index are inversely related to the gait speed in haemodialysis patients. These items and the gait speed, which provide information on the state of vulnerability of the patient, could be markers of frailty.

The purpose of the present study was to determine the association between health-related physical fitness (HRPF) performance and perceived happiness status among adults in Taiwan. A cross-sectional study was conducted, and data derived from the National Physical Fitness Survey in Taiwan 2014–2015 were reviewed. The participants included 27,930 men and 30,885 women, aged 23 to 64 years. Each participant completed a standardized, structured questionnaire and underwent anthropometric variable and HRPF measurements. The happiness outcome of an individual was obtained using the questionnaire, and the results were stratified into happy (very happy, quite happy, and fair) and unhappy (unhappy and not at all happy) groups for perceived happiness status. HRPF measurements were evaluated using cardiorespiratory endurance (3 min step test), muscle strength and endurance (1 min sit-up test), flexibility (sit-and-reach test), and body composition (body mass index (BMI) and waist-to-hip ratio). To determine the existence of a dose–response relationship between HRPF component levels and happiness status, four quartiles of HRPF components were analyzed using multiple logistic regression models. Multiple logistic regression results indicated that with the worst performance level of HRPF components as a baseline, significant associations were observed for the sit-and-reach test (third level: OR = 1.24, 95% CI: 1.02–1.49) and BMI (second level: OR = 0.78, 95% CI: 0.64–0.95) among men. For women, significant associations were observed for the 1 min sit-up test (second level: OR = 1.28, 95% CI: 1.03–1.60; third level: OR = 1.32, 95% CI: 1.04–1.67; fourth (the best) level: OR = 1.48, 95% CI: 1.12–1.95) and BMI (third level: OR = 0.73, 95% CI: 0.58–0.92). The current study suggested that higher values in flexibility and body composition, happiness-related factors, potentially improve the occurrence of happiness among men. Moreover, this positive effect of higher values of muscle strength, endurance, and BMI was observed for the occurrence of happiness in women. However, the relevant mechanism underlying this phenomenon must be further explored.

Willingness To Use

BACKGROUND Traditionally, patients wishing to obtain their prescription medications have had to present themselves physically at pharmacy counters and collect their medications via face-to-face interactions with pharmacy staff. Prescription in Locker Box (PILBOX) is a new innovation which allows patients and their caregivers to collect their medication asynchronously, 24/7 at their convenience, from medication lockers instead of from pharmacy staff and at any time convenient to them instead of being restricted to pharmacy operating hours. OBJECTIVE This study aimed to determine the willingness by patients/caregivers to use this new innovation and factors that affect their willingness. METHODS This prospective cross-sectional study was conducted over 2 months at 2 public primary healthcare centres in Singapore. Patients or caregivers who were at least 21 yo and turned up at the pharmacies to collect medications were administered a self-developed 3-part questionnaire face-to-face by trained study team members, if they gave their consent to participate in the study. RESULTS A total of 222 participants completed the study. About 40% of them participants were willing to use the PILBOX to collect their medications. Amongst the participants who were keen to use the PILBOX service, slightly more than half (i.e. 52.8%) of them were willing to pay for the PILBOX service. The participants felt that the ease of use (3.46±1.21 i.e. mean of ranking score ± standard deviation) of the PILBOX was the most important factor that would affect their willingness to use the medication pick up service. This was followed by “waiting time” (3.37±1.33), cost of using the medication pick up service (2.96±1.44) and 24/7 accessibility (2.62±1.35). This study also found that age (p=0.006), language literacy (p=0.000), education level (p=0.000), working status (p=0.011) and personal monthly income (p=0.009) were factors that affected the willingness of the patients or caregivers to use the PILBOX. CONCLUSIONS Patients and caregivers are keen to use PILBOX to collect their medications for its convenience and the opportunity to save time, if it is easy to use and not costly.

BACKGROUNDRecent evidence suggests a role for hormonal factors in the aetiology of asthma.METHODSData from a large study of women selected from the general population were used to relate treatment with oral hormonal contraceptives (OCP) and postmenopausal hormone replacement therapy (HRT) to the following asthma indicators: self-reported asthma, wheezing, cough at exertion, and use of medication for asthma. The study sample comprised 1536 premenopausal and 3016 postmenopausal women who participated in the third round of the Copenhagen City Heart Study in 1991–4. A total of 377 women were taking OCP (24.5% of premenopausal women) and 458 were on HRT (15.2% of postmenopausal women).RESULTSIn premenopausal women 4.8% reported having asthma. The prevalence of self-reported asthma, wheeze, use of asthma medication, and cough at exertion was not significantly related to use of OCP. In postmenopausal women the prevalence of self-reported asthma was 6.2%. A weak but consistent association was observed between HRT and self-reported asthma (OR 1.42 (95% CI 0.95 to 2.12)), wheeze (OR 1.29 (95% CI 1.02 to 1.64)), cough at exertion (OR 1.34 (95% CI 1.01 to 1.77)), and use of asthma medication (OR 1.45 (95% CI 0.97 to 2.18)).CONCLUSIONSIn this study of the general population no relationship was found between the use of OCP and asthma. Although an association was observed between HRT and asthma and asthma-like symptoms, this was relatively weak and it is concluded that there is no necessity to change present prescription practice.
