Abstract Background: The hip abductor muscles, primarily the gluteus medius, play an important role in stabilizing the pelvis during gait. Gluteus medius weakness is associated with biomechanical changes and musculoskeletal disorders. Obese individuals can have great difficulty maintaining abductor muscular function due to being overweight and possibly experiencing a decrease in muscle mass. However, it is still unclear whether the musculature of obese individuals can compensate for these changes. Therefore, the aim of this study was to compare gluteus medius strength between obese and normal-weight individuals using a digital hand-held dynamometer.Methods: Twenty-five obese (BMI > 35 kg/m2) participants were matched for sex, age, and height with normal-weight individuals. Gluteus medius strength was measured by a single examiner using a belt-stabilized hand-held digital dynamometer placed on the knee of the individuals positioned in lateral decubitus. Three measurements were recorded with rest intervals, and only the highest value measured for each limb was used for analysis. The differences between pairs were calculated, and the normality of the data was assessed using the Shapiro-Wilk test (p < 0.05). The matrices of the variables were standardized and analysed using principal component analysis (PCA).Results: For the strength variables (Newtons) on both sides, no significant differences were detected between the groups (p > 0.05). However, significant differences were detected in these variables between the groups (p < 0.05) when the measurements were normalized to body weight (Newtons/kilograms). PCA indicated that both the absolute and normalized values of strength are lower in obese than in normal-weight individuals.Conclusions: These findings indicate that obese individuals have the same or less strength (PCA) to move more mass, which may suggest a relative weakness that induces functional limitations.Trial registration: The study was approved by the UNIOESTE Human Research Ethics Committee (#1.180.202) in July 2015.

Abstract Background The hip abductor muscles play an important role in stabilizing the pelvis during gait, its main function being performed by the gluteus medius. Gluteus medius insufficiency is associated with biomechanical alterations and musculoskeletal disorders. Due to overweight and a possible muscle mass decrease, maintaining the abductor muscular function can be a great challenge for obese. However, it is still unclear whether the musculature of obese individuals manages to compensate for these alterations. Therefore, the aim of this study was to compare the gluteus medius strength between obese and normal weight individuals using a digital hand-held dynamometer. Methods Twenty-five obese (body mass index > 35 kg / m 2 ) participated in the study, being matched in gender, age, and height with normal weight individuals. The gluteus medius strength was measured by a single examiner using a belt-stabilized hand-held digital dynamometer on the knee of individuals positioned in lateral decubitus. Three measurements were recorded with rest intervals, considering only the highest value measured for each limb for analysis. The difference between pairs was calculated and the data distribution pattern was assessed using the Shapiro-Wilk test (p < 0.05), and the matrices of the variables were standardized and analyzed using the principal component analysis (PCA). Results For the strength variables (Newtons) on both sides, no statistical differences were detected between groups (p > 0.05). However, statistical differences were detected in these variables between groups (p < 0.05) when normalizing the measurements in relation to individuals' weight (Newtons / kilograms). The PCA indicates that both strength in absolute values and normalized by weight are reduced in obese individuals. Conclusions These findings indicate that obese individuals have the same or lower strength (PCA) to move more mass, which may suggest a relative weakness that induces functional limitation.

AbstractObjective:Dietary patterns have been pointed out as useful diet quality indicators, but evidence about their relationship to metabolic phenotypes is still scarce. Thus, the present study aimed to verify the relationship between dietary patterns and metabolic phenotypes in Brazilian adults.Design:Cross-sectional study. A food consumption frequency questionnaire assessed food consumption profiles. Metabolic phenotypes were defined based on the criteria of the National Health and Nutrition Examination Survey: overweight or normal weight and metabolically healthy (MHOW and MHNW) or unhealthy (MUOW and MUNW). Dietary patterns were established through exploratory factor analysis and principal component analysis. The associations were tested using multinomial logistic regression.Setting:Viçosa, Minas Gerais, Brazil.Participants:Individuals (n 896) aged 20–59 years of both sexes, selected using probabilistic sampling.Results:Three dietary patterns were identified: Unhealthy pattern (alcoholic beverages, oils and fats, condiments, soda and juice, sugars and sweets, snacks, and meat and derivatives), Traditional pattern (culinary preparations, beans, milk and dairy products, and coffee and tea) and Healthy pattern (vegetables and fruits, whole grains, chicken and fish, and skimmed milk). Unhealthy pattern was positively associated with the MHOW and MUOW phenotypes in the fourth quartile (OR = 1·84; 95 % CI 1·06, 3·22) and in the third (OR = 1·94; 95 % CI 1·11, 3·39) and fourth (OR = 2·56; 95 % CI 1·41, 4·64) quartiles of consumption, respectively. Healthy pattern was also associated with these phenotypes.Conclusions:Both the pattern comprising energy-dense foods and the healthier pattern were associated with overweight phenotypes among Brazilian adults.

AbstractThe reduced (GSH)-to-oxidized (GSSG) glutathione ratio represents a dynamic balance between oxidants and antioxidants. However, redox status in adolescents with obesity and anemia has not been investigated. This study investigated the association of erythrocyte GSH redox status (GSH, GSH:GSSG ratio, and glutathione peroxidase [GPx] activity) with anemia and adiposity in adolescents. This case–control study nested in a cross-sectional study enrolled 524 adolescents (268 boys; 256 girls). The prevalence of anemia in overweight and obesity (OWOB) was 5.2% in boys and 11.7% in girls. The GSH:GSSG ratio and GPx activity were significantly higher in girls than in boys (p < 0.001), in anemic than in non-anemic subjects (p < 0.001), and in OWOB than in normal-weight subjects (p < 0.001). Similarly, significantly higher GSH: GSSG level (p < 0.001) and GPx activity (p < 0.001) were found in subjects with 90th percentile waist circumference than in those with < 90th percentile. GPx and GSH:GSSG were positively associated with anemia after adjusting for age, sex, and body mass index (adjusted odds ratio, adjOR [95% confidence interval, CI] 2.18 [1.44–3.29]) or tertiles (adjOR [95% CI], T3 = 2.49 [1.03–6.01]). A similar association was noted for GSH and GPx. A compensatory increased redox defense mechanism exists in anemia and obesity among adolescents without metabolic disturbances.

IntroductionClinical teaching visits (CTVs) are formative workplace-based assessments that involve a senior general practitioner (GP) observing a clinical practice session of a general practice registrar (specialist vocational GP trainee). These visits constitute a key part of Australian GP training. Despite being mandatory and resource-intensive, there is a paucity of evidence regarding the content and educational utility of CTVs. This study aims to establish the content and educational utility of CTVs across varying practice settings within Australia, as perceived by registrars and their assessors (‘CT visitors’). In addition, this study aims to establish registrar, CT visitor and practice factors associated with CTV content and perceived CTV utility ratings.Methods and analysisThis study will collect data prospectively using online questionnaires completed soon after incident CTVs. Participants will be registrars and CT visitors of CTVs conducted from March 2020 to January 2021. The setting is three Regional Training Organisations across four Australian states and territories (encompassing 37% of Australian GP registrars).Outcome factors will be a number of specified CTV content elements occurring during the CTV as well as participants’ perceptions of CTV utility, which will be analysed using univariate and multivariable regression.Ethics and disseminationEthics approval has been granted by the University of Newcastle Human Research Ethics Committee, approval number H-2020-0037. Study findings are planned to be disseminated via conference presentation, peer-reviewed journals, educational practice translational workshops and the GP Synergy research subwebsite.

Background: Environmental contamination with elevated levels of copper (Cu), cobalt (Co), iron (Fe), zinc (Zn), lead (Pb), chromium (Cr6+), cadmium (Cd), and nickel (Ni)—all states of which are found in Uganda—raises health risk to the public. Pb, Cr6+, Cd, and Ni for instance are generally considered nonessential to cellular functions, notwithstanding the importance of the oxidative state of the metals in bioavailability. As such, we aimed in this study (i) to evaluate heavy metal concentrations in four vegetables from a typical open-air market in Uganda, (ii) to assess the safety of consuming these vegetables against the World Health Organization (WHO) recommended limits of heavy metals consumption, and (iii) to formulate a model of estimated daily intake (EDI) among consumers in the country. Methods: This was a cross-sectional study conducted in five georeferenced markets of Bushenyi district in January 2020. Amaranthus, cabbages, scarlet eggplants, and tomatoes were collected from open markets, processed, and analyzed by atomic absorption spectrometry. Modeled EDI, principal component (PCA) and cluster analysis (CA) were conducted to identify relationships in the samples. Results: The levels of essential elements in the four vegetables were found to fall from Co > Cu > Fe > Zn. Those of non-essential metals were significantly higher and followed the pattern Cd > Cr > Pb > Ni. The highest EDI values were those of Cu in scarlet eggplants, Zn in amaranthus, Fe in amaranthus, Co in amaranthus, Pb in cabbages, total Cr in scarlet eggplant, Cd in cabbages and tomatoes, and Ni in cabbages. In comparison to international limits, EDIs for Zn, Cu, Co and Fe were low while Ni in cabbages were high. PCA showed high variations in scarlet eggplant and amaranthus. The study vegetables were found to be related with each other, not according to the location of the markets from where they were obtained, but according to their species by CA. Conclusion: The presence of non-essential elements above WHO limits raises policy challenges for the consumption and marketing of vegetables in the study area. Furthermore, low EDIs of essential elements in the vegetables create demand for nutritious foods to promote healthy communities.

Background:This survey aims to assess the prevalence of physical activity among adult Lebanese, and to report the relationship between sociodemographic variables and physical activity behavior, highlighting the correlates discouraging people to carry out physical activity.Methods:A cross-sectional study using an anonymous self-reported questionnaire was conducted on 346 adults from four Lebanese districts. Demographic characteristics, physical activity, smoking status, alcohol consumption, and medical history were obtained.Results:Prevalence of physical activity among Lebanese adults was 55.5% (192/346). Age, BMI, marital status, medical history, occupation, educational level, and smoking were significantly associated with physical activity (P < .05). Inactive obese participants were about three times more likely to report hypertension and diabetes than inactive normal weight participants (P = .013). BMI was significantly higher among inactive participants (P = .014).Conclusion:Physical activity among Lebanese adults was comparable to other populations. Married, non–office workers, and smokers were the main correlates of physical inactivity in Lebanese adulthood.
