Sociodemographic, nutritional and anthropometric factors determining overweight and obesity in an adult moroccan population

BACKGROUND: Knowledge of the determinants of the weight status of a population is important to be considered in actions aimed at improving public health. OBJECTIVE: The aim was to study the sociodemographic, nutritional and anthropometric factors associated with overweight and obesity in an adult Moroccan population. METHODS: This study focused on 507 adult subjects from the Rabat-Salé-Kénitra region in Morocco, according to a validated conceptual and methodological framework. Sociodemographic data were collected using a questionnaire, physical activity (PA) was assessed by the Marshal questionnaire, dietary intakes were estimated by a “dietary history” type survey. Anthropometric parameters were also measured using impedancemetry and a tape measure. RESULTS: The majority of the study population was 20 to 29 years old, females, urban and had an medium socio-economic level (SEL). The population’s dietary intake was high in calories, proteins, carbohydrates, fats, sugars, and sodium; and low in vitamin C, vitamin A, vitamin E, folic acid, iron, calcium and zinc. Univariate analysis revealed that overweight and obesity are associated with the 30–39 yrs age group, average SEL, insufficient PA, high intakes of calories, proteins, carbohydrates and lipids, as well as with high waist circumference and excessive body fat percentage. CONCLUSION: Factors associated with overweight and obesity were identified in the study population, revealing a coexistence of high intakes of energy and macronutrient and low intake of several micronutrients. The prevalence of deficiencies and excesses of these intakes testifys of a double burden of malnutrition in this population. The results are very relevant for guiding nutritional education actions among this population.

Association of osteoporosis with sarcopenia and its components among community-dwelling older Chinese adults with different obesity levels: A cross-sectional study.

We aimed to investigate whether sarcopenia and its components are associated with osteoporosis in community-dwelling older Chinese adults with different obesity levels. This cross-sectional study included 1938 participants (42.1% male) with a mean age of 72.1 ± 5.9 years. The categorization of individuals into various weight categories was based on the Working Group on Obesity in China's criteria, utilizing the body mass index (BMI) as follows: underweight, BMI < 18.5 kg/m2; normal weight, 18.5 ≤ BMI < 24 kg/m2; overweight, 24 ≤ BMI < 28 kg/m2; and obesity, BMI ≥ 28 kg/m2. In this research, the osteoporosis definition put forth by the World Health Organization (bone mineral density T-score less than or equal to -2.5 as assessed by Dual-energy X-ray absorptiometry (DXA)). Sarcopenia was defined according to the diagnostic criteria of the Asian Working Group for Sarcopenia. The prevalence of osteoporosis was highest in the underweight group and gradually decreased with increasing BMI (Underweight: 55.81% vs Normal weight: 45.33% vs Overweight: 33.69% vs Obesity: 22.39). Sarcopenia was associated with elevated odds of osteoporosis in normal-weight subjects independent of potential covariates (OR = 1.70, 95% CI = 1.22-2.35, P = .002). In normal-weight participants, a higher appendicular skeletal muscle mass index (ASMI) was associated with a reduced risk of osteoporosis (OR = 0.56, 95% CI = 0.42-0.74, P < .001). In this study, we found that the prevalence of osteoporosis was highest in the underweight group and gradually decreased with increasing BMI. Sarcopenia, body fat percentage, and ASMI were associated with elevated odds of osteoporosis in normal-weight subjects independent of potential covariates, and higher percent body fat (PBF) was associated with an increased risk of osteoporosis in overweight people, and no such association was found in other weight groups. Different amounts of adipose tissue and muscle mass may alter bone biology. Further longitudinal follow-up studies are required to more accurately assess the risk of osteoporosis and sarcopenia in different weight populations. This cross-sectional study found that the prevalence of osteoporosis was highest in the underweight group and gradually decreased with increasing BMI. Sarcopenia was associated with elevated odds of osteoporosis in normal-weight subjects independent of potential covariates.

정상 체중 비만 성인의 체지방 감량을 위한 한약 처방의 활용: 후향적 차트 리뷰

Objectives Normal weight obesity (NWO) is defined as a normal body weight according to Body Mass Index (BMI) but with a high body fat percentage. NWO is associated with metabolic abnormalities and cardiovascular risk factors, thereby emphasizing the importance of body fat loss. The objective of this study is to evaluate changes in weight and body fat with NWO who were prescribed Korean herbal medicine. Methods A retrospective chart review was conducted for subjects with NWO, within the normal weight range but with over 30% body fat percentage. These subjects were prescribed herbal medicine for a 12-week between March 2021 and May 2023. Weight (kg), body fat mass (kg), body fat percentage (%) and % Fat Free Mass (FFM) loss/weight loss (%FFML) were assessed before and after the period. Reported adverse events were evaluated for severity, causality, and system-organ classes. Results A total of 42 subjects were included (mean±SD, weight 57.38±3.45 kg, body fat percentage 33.65±2.12%). The average weight loss rate was 6.99±3.22% with a reduction of 4.08±1.95 kg, while the body fat loss rate averaged 18.00± 0.08% with a decrease of 3.54±1.73 kg. The average of %FFML was 21.89±0.16%. Most adverse events reported were mild (90.9%) in severity, and the likelihood of events being 'Unlikely' increased from 48.8% to 64.3% as the program progressed. Conclusions The administration of Korean herbal medicine can be considered an appropriate method to alleviate normal weight obesity, without causing serious adverse reactions. Further well-designed controlled trials and clinical studies with the analysis of hematological indicators are needed to validate its efficacy.

Dominant Somatotype Development in Relation to Body Composition and Dietary Macronutrient Intake among High-Performance Athletes in Water, Cycling and Combat Sports

Relevant properties of the somatotype as important indicators can be associated with the body composition characteristics as well as both metabolic and bio-mechanical efficiency of athletes in the sport concerned. The primary aim of this single cross-sectional study was to determine the somatotype profiles in association with body composition and nutritional profiles among Lithuanian elite athletes (n = 189) involved in water, cycling and combat sports. The body composition along with the somatotype profiles and the nutritional status of athletes were evaluated using a battery of multiple frequency (5, 50, 250, 550, and 1000 kHz) bioelectrical impedance analysis (BIA) and a 3-day food record analysis. In terms of the prediction for athletes to be classified as endomorphs, mesomorphs or ectomorphs, the linear discriminant analysis was conducted to assess the grouping of samples. Both the multiple linear regression and multivariate logistic regression statistical analyses were performed to explore the associations between the independent and dependent variables. The central tendency values for the somatotype components of endomorphy, mesomorphy and ectomorphy in athletes playing water, cycling and combat sports were 4.3–4.9–3.4, 4.3–4.8–3.4 and 4.5–5.5–2.9, respectively. The central mesomorph somatotype with a trend towards endomorphy was dominant and varied according to a high muscle-to-fat ratio in elite athletes. Significant (p ≤ 0.001) positive associations between both endomorphy and mesomorphy values and higher body fat percentage as well as lower and upper limb muscle mass were identified. The lower levels of trunk muscle mass were related to athletes’ endomorphy and mesomorphy, too. Furthermore, in the athletes’ sample under analysis, high-level mesomorphs were prone to consume low-carbohydrate (adjusted odd ratio (AOR) 0.5, 95% confidence interval (CI) 0.2; 0.9) and high-protein diets (AOR 2.5, 95% CI 1.1; 5.5). Contrastingly, the elite athletes with a higher expression of endomorphy were on high-carbohydrate (AOR 5.4, 95% CI 1.1; 8.3) and high-fat diets (AOR 4.6, 95% CI 1.5; 7.1) along with insufficient protein diet (AOR 0.3, 95% CI 0.1; 0.9). Finally, whilst nutrition goals as a mediator can play a significant role in undergoing the maintenance of balance between the optimal body composition for athletic performance and the development of an ecto-mesomorphic somatotype, the elite athletes with higher levels of endomorphy value should be aware of lowering the body fat percentage coupled with dietary fat reduction and higher protein intakes. The findings obtained from the study may serve as an antecedent for a more targeted management of the elite athletes’ training process. Somatotyping as an additional assessment method can be successfully deployed in choosing correct coaching techniques, contributing to talent recognition processes or identifying reference morphometric parameters in elite athletes competing in water, cycling and combat sports.

Prevalence and associated factors of locomotive syndrome in young Japanese adults: a cross-sectional study

BackgroundThe onset of locomotive syndrome (LS) precedes that of frailty. Therefore, the first step in extending healthy life expectancy is to implement measures against LS in young adults. The aim of this study was to investigate the prevalence of LS and its associated factors in young adults for early detection and prevention of LS.MethodsThe participants of this study comprised 413 university students specializing in health sciences (192 males and 221 females) with an average age of 19.1 ± 1.2 years. All participants voluntarily participated in the study and reported no serious health problems. The presence or absence of LS was evaluated using the stand-up test, two-step test, and the 25-question Geriatric Locomotive Function Scale. Additionally, musculoskeletal assessment (one-leg standing, squatting, shoulder elevation, and standing forward bend), body composition analysis (weight, body mass index, body fat mass, body fat percentage, skeletal muscle mass index (SMI), and phase angle), handgrip strength test, physical activity assessment, and nutritional assessment were conducted. Sex-stratified analyses were performed, comparing groups with and without LS. Factors associated with LS were explored using binomial logistic regression.ResultsOf the 413 young adults studied, 86 individuals (20.8%) were found to have LS. When stratified by sex, LS was observed to have a considerably higher prevalence in females (55, 24.9%) than in males (31, 16.1%). In males, the notable differences between the groups with and without LS were observed in one-leg standing and phase angle, whereas in females, differences were identified in body fat mass, body fat percentage, SMI, musculoskeletal pain, and handgrip strength. Two types of binomial logistic regression analysis revealed that the inability to perform one-leg standing was associated with LS in males, while the presence of musculoskeletal pain and a high body fat percentage were identified as factors associated with LS in females.ConclusionsOne in five young adults were found to have LS in this study, underscoring the necessity for early intervention and LS health education. Furthermore, effective management of musculoskeletal pain is also crucial.

Evaluation of the relationship between body composition and dietary habits of physically active people with disabilities

Physical activity offers numerous physical and mental health benefits for individuals with disabilities, while nutrition plays a crucial role in maintaining bodily homeostasis. This study aimed to assess the relationship between body composition and dietary habits among physically active people with disabilities. Fifty-five participants aged 16 to 61, including 28 with disabilities and 27 without, were included in the study. The FFQ-6 questionnaire, Tanita body composition analyzer, and Stadiometer were utilized. No significant differences in BMI were observed between the two groups. However, individuals with disabilities showed higher body fat, metabolic age, or pulse values, whereas the control group exhibited higher muscle mass, muscle quality, body type, or bone mass. Participants with disabilities were more likely to consume vegetables (p = 0.004) and animal fats (p = 0.027), while those without disabilities were more inclined to consume fast food, instant products (p = 0.006), sweetened beverages (p < 0.001), and alcohol (p < 0.001). People with disabilities often have a higher percentage of body fat, cautioning against the consumption of processed fruits, dried fruits, fast food, and red meat. Conversely, in non-disabled individuals, frequent consumption of eggs, animal fats, sugar, and sweets is not recommended due to the potential for increased body fat, visceral fat, and higher BMI.

Discriminating factors of body composition characteristics for academic performance in nursing college students: a cross-sectional study

BackgroundPoor body composition may affect health status, and better body composition is often associated with better academic performance. Nursing students face heavy academic and practical pressures, and the relationship between body composition and academic performance in this group is not fully understood.MethodsThis cross-sectional observational study used de-identified student data from a university of technology in southern Taiwan to analyze the correlation between body composition characteristics and academic performance using regression models.ResultsA total of 275 nursing college students were divided into four groups according to academic performance. The group with the lowest academic performance had a lower percentage of body fat (P < 0.05) but a higher percentage of muscle mass (P < 0.05) than the other three groups. Academic performance was positively correlated with percentage of body fat (R = 0.16, P < 0.01) and body age (R = 0.41, P < 0.01), but was negatively correlated with percentage of muscle mass (R = − 0.16, P < 0.01). Percentage of body fat, visceral fat area, and body age were significant discriminators of academic performance (P < 0.05).ConclusionsThe relationship between academic performance and body composition among nursing college students is not straightforward. Contrary to our initial hypothesis, students with higher academic performance tended to have a higher percentage of body fat and a lower percentage of muscle mass. Percentage of body fat, visceral fat area, and body age were significant discriminators of academic performance, indicating that body composition should be considered an important factor in nursing education and practice.

Effects of Partial Knockout of Skeletal Muscle Dynamin-Related Protein 1 on Skeletal Muscle Characteristics in Lean and Obese Mice

Dynamin-related protein 1 (Drp1) is a key regulator of mitochondrial fission and plays an essential role in maintaining skeletal muscle homeostasis. Recent studies reported muscle atrophy in mice when skeletal muscle Drp1 content was reduced. However, whether such atrophic phenotype also exists in diet-induced obese mice remains unknown. We recently reported that reducing skeletal muscle Drp1 resulted in improved whole-body glucose homeostasis and insulin sensitivity in diet-induced obese mice, but not lean healthy mice, suggesting Drp1 may exert divergent effects on physiological phenotypes under different conditions. OBJECTIVE: To determine the effects of partial knockout of skeletal muscle-specific heterozygous Drp1 (mDrp1+/−) on body composition, energy expenditure and skeletal muscle physiology in lean and obese mice. HYPOTHESIS: mDrp1+/− exhibits divergent alterations in physiological characteristics between lean healthy and obese mice. Methods: Tamoxifen-inducible mDrp1+/− mouse model was generated. Nine-week-old male and female mDrp1+/− and wildtype (WT) mice (n=6-8/group) were fed with either a high-fat diet (HFD) or low-fat diet (LFD) for four weeks, received tamoxifen injections, and remained on their respective diet for another four to six weeks. A DXA scan was conducted to measure body composition. Mice were housed in Promethion metabolic cages for 48 hours to measure energy expenditure. Isolated soleus (SOL) and extensor digitorum longus (EDL) muscles were used for assessing muscle cross sectional area (CSA) and contractility. Results: HFD-fed mice had significantly higher percentage of body fat ( p = 0.045) and lower respiratory exchange ratio ( p &lt;0.0001) than LFD-fed mice, regardless of genotype. Regarding skeletal muscle characteristics, SOL from mDrp1+/− mice exhibited larger CSA ( p = 0.052) than WT mice, regardless of diet. However, there were no differences in muscle force or fatigue resistance in SOL between groups. In contrast, EDL muscle isolated from mDrp1+/− mice fed with HFD had greater muscle force than WT mice, but interestingly the force was lower in mDrp1+/−/LFD mice than WT/LFD mice (genotype x diet interaction effect, p = 0.001). Consistently, a significant interaction was found in both twitch and tetanic rate of force development and relaxation rates (genotype x diet interaction effect, p = 0.022, p = 0.033, p = 0.040, and p = 0.020, respectively). There was no difference in EDL muscle CSA between groups. CONCLUSION: Our data suggests that partial knockout of Drp1 in skeletal muscle induced divergent effects on CSA, force production and fatigability between diet induced obese and lean healthy mice.

Childhood obesity's influence on socioeconomic disparities in young adolescents’ mental health

PurposeWe investigated whether socioeconomic inequalities in young adolescents’ mental health are partially due to the unequal distribution of childhood obesity across socioeconomic positions (SEP), i.e. differential exposure, or due to the effect of obesity on mental health being more detrimental among certain SEPs, i.e. differential impact. MethodsWe studied 4660 participants of the Generation R study, a population-based study in the Netherlands. SEP was estimated by mother’s education and household income at age five of the child. We estimated the contribution of the mediating and moderating effects of high body fat percentage to the disparity in mental health. This was done through a four-way decomposition using marginal structural models with inverse probability of treatment weighting. ResultsComparing children with the least to most educated mothers and the lowest to highest household income, the total disparity in emotional problems was 0.98 points (95%CI:0.35–1.63) and 1.68 points (95%CI:1.13–2.19), respectively. Of these total disparities in emotional problems, 0.50 points (95%CI:0.15–0.85) and 0.24 points (95%CI:0.09–0.46) were due to the differential exposure to obesity. Obesity did not contribute to disparities in behavioural problems. ConclusionAddressing the heightened obesity prevalence among children in low SEP families may reduce inequalities in emotional problems in early adolescence.

Investigation and Comparison of Maternal Pre-Pregnancy Body Mass Index Coupled with Gestational Weight Gain on Maternal-Fetal Complications Based on US and Chinese Guidelines: A Retrospective Study.

Compared to Western populations, Chinese and Asians possess distinct genetics, lifestyles, and dietary habits. They tend to have shorter stature, lower Body Mass Index (BMI), and higher body fat percentages than Western populations. The aim of this study was to compare disparities in maternal-fetal outcomes by combining pre-pregnancy BMI and gestational weight gain (GWG) based on distinct US and Chinese guidelines. A total of 2,271 pregnant women who received perinatal care at Fooyin University Hospital from 2016 to 2021 were included. Logistic regression analysis categorized women into twelve groups based on the two criteria to explore the relationships between BMI and GWG, and maternal-fetal outcomes. Among the subjects, only 23.2% and 21.8% women had a normal weight BMI and adequate GWG, based on US and Chinese criteria, respectively. As BMI and GWG increase, the likelihood of developing complications such as gestational diabetes, gestational hypertension or preeclampsia, Cesarean section, and Large for Gestational Age also rises. Conversely, underweight women with excessive GWG exhibited lower risk of preterm birth either by US or Chinese guidelines. Two criteria exhibited similar odds for investigated outcomes, except for gestational hypertension or preeclampsia. Women had more than double the odds of developing gestational hypertension or preeclampsia when using US criteria compared to Chinese criteria. Therefore, it is essential for Asian, especially Chinese women, to be aware of the differences in adverse outcomes such as gestational hypertension or preeclampsia when using US criteria.

Olfactory genes affect major depression in highly educated, emotionally stable, lean women: a bridge between animal models and precision medicine

Most current approaches to establish subgroups of depressed patients for precision medicine aim to rely on biomarkers that require highly specialized assessment. Our present aim was to stratify participants of the UK Biobank cohort based on three readily measurable common independent risk factors, and to investigate depression genomics in each group to discover common and separate biological etiology. Two-step cluster analysis was run separately in males (n = 149,879) and females (n = 174,572), with neuroticism (a tendency to experience negative emotions), body fat percentage, and years spent in education as input variables. Genome-wide association analyses were implemented within each of the resulting clusters, for the lifetime occurrence of either a depressive episode or recurrent depressive disorder as the outcome. Variant-based, gene-based, gene set-based, and tissue-specific gene expression test were applied. Phenotypically distinct clusters with high genetic intercorrelations in depression genomics were found. A two-cluster solution was the best model in each sex with some differences including the less important role of neuroticism in males. In females, in case of a protective pattern of low neuroticism, low body fat percentage, and high level of education, depression was associated with pathways related to olfactory function. While also in females but in a risk pattern of high neuroticism, high body fat percentage, and less years spent in education, depression showed association with complement system genes. Our results, on one hand, indicate that alteration of olfactory pathways, that can be paralleled to the well-known rodent depression models of olfactory bulbectomy, might be a novel target towards precision psychiatry in females with less other risk factors for depression. On the other hand, our results in multi-risk females may provide a special case of immunometabolic depression.

Differences in Anthropometric Measures Based on Sex, Age, and Health Status.

Obesity is a worldwide health problem. We conducted detailed analyses of anthropometric measures in a comprehensive, population-based, current cohort in Germany. In the German National Cohort (NAKO), we analyzed cross-sectional data on body mass index (BMI), waist and hip circumference, subcutaneous (SAT) and visceral adipose tissue (VAT) as measured by ultrasound, and body fat percentage. The data were stratified by sex, age, and self-reported physicians' diagnoses of cardiovascular diseases (CVD), metabolic diseases (MetD), cardiometabolic diseases (CMD), and cancer. Data were available from 204 751 participants (age, 49.9 ± 12.8 years; 50.5% women). Body size measures generally increased with age. Men had a higher BMI, larger waist circumference, and more VAT than women, while women had a larger hip circumference, more SAT, and a higher body fat percentage than men. For example, the mean BMI of participants over age 60 was 28.3 kg/m2 in men and 27.6 kg/m2 in women. CVD, MetD, and CMD were associated with higher anthropometric values, while cancer was not. For example, the mean BMI was 25.3 kg/m2 in healthy women, 29.4 kg/m2 in women with CMD, and 25.4 kg/m2 in women with cancer. Obesity is widespread in Germany, with notable differences between the sexes in anthro - pometric values. Obesity was more common in older participants and those with chronic diseases other than cancer. Elevated values were especially common in multimorbid individuals.

Inflammatory Bowel Disease exercise and diet (IBDeat) habits study: exploring lifestyle habits and cardiometabolic disease risk factors

Patients with inflammatory bowel disease (IBD) have higher risk of developing cardiometabolic diseases due to chronic gut and systemic inflammation which promotes atherogenesis. Adopting healthy lifestyle habits can prevent development of cardiometabolic diseases, but can be challenging for people with IBD. The IBD exercise and diet (IBDeat) habits study describes the lifestyle habits and cardiometabolic disease risk factors of adults with IBD in Aotearoa, New Zealand (NZ).This is a cross-sectional study including adult NZ IBD patients recruited online via Crohn’s and Colitis NZ and Dunedin hospital from 2021 to 2022. An online questionnaire collected demographics, smoking status, comorbidities, medications, disease severity scores, quality of life, physical activity, and dietary intake. The Dunedin cohort had physical measurements taken including anthropometrics, handgrip strength, blood pressure, body composition (bioelectrical impedance), blood nutritional markers, and faecal calprotectin. Data were compared to established reference values and linear regression analysis investigated associations between lifestyle habits and cardiometabolic risk factors. The study received University of Otago ethical approval (reference: H21/135). A total of 213 adults with IBD (54% Crohn’s disease; 46% ulcerative colitis) completed the online questionnaire and a subset of 102 from Dunedin provided physical measurements. Participants characteristics were: median age 37 (IQR 25, 51) years, 71% female, 82% NZ European, 4% smokers, and 1.4% had active IBD. Thirty-five percent of participants had at least one comorbidity and 34% of participants had poor quality of life. Known dietary risk factors associated with cardiometabolic diseases were common: low intakes of vegetables (77%), fruit (51%), fibre (35%) and high intakes of total fat (84%) and saturated fat (98%). Physical activity recommendations were met by 61% of participants and 63% reported barriers to being more active from fatigue (63%) and joint pain (54%). Other cardiometabolic risk factors were common in the Dunedin cohort: high LDL (79%) and total cholesterol (76%), central adiposity (64%), high body fat percentage (44%), high blood pressure (26%), and low handgrip strength (25%). Regression analysis showed that vegetable (per serve) and carbohydrate (per 5% of total daily energy intake (TE)) were associated with 0.22 mmol/L (95%CI 0.43, 0.013) and 0.20 mmol/L (95%CI 0.34, 0.057) lower LDL cholesterol. Discretionary food items were associated with higher LDL cholesterol, 0.11 mmol/L per daily serve (95%CI 0.028, 0.19). A 5% difference in TE intake from carbohydrate was associated with 1.11% (95%CI 2.22%, 0.0038%) lower body fat percentage while protein was associated with 3.1% (95%CI 0.81%, 5.39%) higher body fat percentage. Physical activity had weak associations with cardiometabolic disease risk factors. Adults with IBD have multiple modifiable risk factors for cardiometabolic diseases. Vegetable and carbohydrate intake were associated with lower LDL cholesterol concentration while discretionary food items showed otherwise. Protein intake was associated with higher body fat percentage.

Gender-specific reference values of dynamometric and non-dynamometric trunk performance in individuals with different body fat percentages: A preliminary study.

Trunk muscles maintain steady effort with adequate strength and endurance. When the muscle performance is subpar, it might cause lower back discomfort. No reference for trunk strength and endurance has been established previously. The aim of this study was to determine the normative reference values for dynamometric and non-dynamometric tests in people with various body fat percentages. Two hundred sixty-four participants aged 19-40 years old were recruited in this cross-sectional study. The Siri equation was used to calculate the individuals body fat proportions, which were divided into normal, high, and very high body fat for men and women. The Modified Sorenson's and the Back-Leg-Chest Dynamometric tests were utilized to measure muscular performance. The means of strength in females with normal, high, and very high body fat percentages were 27.39, 25.75, and 25.37 N/m2, respectively. The males in the same category had the means of 56.48, 51.79, and 60.17 N/m2, respectively. The highest mean of endurance in females was in those with normal body fat percentage (42.28), so did males (71.02). Our findings suggest that males had higher trunk muscle strength and endurance than females, and normal-body-fat individuals had the greatest endurance regardless of gender.

Intervention with Purple Okra Pudding and Supplement to Improve Antioxidant Status in Healthy Adults

This research aimed to analyze the potency of purple okra-based products in improving the antioxidant status of healthy adults. Thirty adults with high body fat percentages were allocated into three groups: the first group was treated with 100 g of purple okra pudding/day, the second group was provided with a purple okra extract supplement that contained 3.80 g of extract/day, and the third group was a control group. The intervention was carried out for 28 days. All subjects were exposed to nutrition education, and data on their characteristics, food intake, and physical activity level were collected. The results showed that purple okra pudding and supplement had antioxidant activity of 0.39 and 455.39 mg AEAC/g extract, IC50 of 543.79 and 71.78 ppm, and total phenol of 6.21 and 24.49 mg GAE/g extract, respectively. There were significant differences among subject groups in energy, protein, and fat intake as well as physical activity level. The group treated with purple okra pudding showed a significantly higher ΔSOD after the intervention, most probably due to the role of antioxidants contained in purple okra in upregulating antioxidant defense. In contrary, there was a declining trend of ΔSOD in the group treated with purple okra extract supplement. The different effects observed between the two groups might be due to the different phenol contents between the two intervention products. This study showed that purple okra has the potential as a functional food and health supplement in improving the antioxidant status of healthy adults with high body fat percentages as indicated by a higher change of SOD level (0.08 u/mL) in comparison to the control (-0.07 u/mL).

Exercise Combined with a Low-Calorie Diet Improves Body Composition, Attenuates Muscle Mass Loss, and Regulates Appetite in Adult Women with High Body Fat Percentage but Normal BMI.

The present study aimed to examine the effects of a 500 kcal reduction in daily energy intake alone and in combination with 90 min of moderate-to-vigorous aerobic exercise per week on body weight, body composition, and appetite sensations in young women with normal BMI and abnormal body fat percentage. sixty-six young women with normal BMI and abnormal body fat percentage (21.33 ± 1.20 kg/m2 and 34.32 ± 2.94%) were randomly assigned into three groups: (1) caloric restriction (CR; n = 22), (2) caloric restriction with exercise (CR-EX; n = 22), and (3) control (C; n = 22). Data on anthropometry, blood samples, and subjective appetite sensations pre- and post-intervention were collected. After 4 weeks of intervention, CR and CR-EX groups both reduced body weight, fat percentage, and waist and hip circumferences compared to the C group (p < 0.05). Muscle mass of the CR group was significantly lower than that of the C group (-1.21 ± 0.86 kg vs. -0.27 ± 0.82 kg, p < 0.05), and no significant difference between CR-EX and C groups was observed. For appetite sensations, the subjects of the CR group showed significant increases in change of scores in desire to eat and prospective consumption than that of the C group (p < 0.05), while no significant difference between CR-EX and C groups was observed. A 500 kcal reduction in daily energy intake alone and in combination with 90 min of moderate-to-vigorous aerobic exercise per week could both reduce weight and improve body composition in young adult women with normal BMI and abnormal body fat percentage. More importantly, calorie restriction combined with exercise intervention was superior to calorie restriction alone in improving muscle mass loss and regulating appetite sensations.

Biologically Informed Polygenic Scores for Brain Insulin Receptor Network Are Associated with Cardiometabolic Risk Markers and Diabetes in Women.

To investigate associations between variations in the co-expression-based brain insulin receptor polygenic score and cardiometabolic risk factors and diabetes mellitus. This cross-sectional study included 1,573 participants from the Helsinki Birth Cohort Study. Biologically informed expression-based polygenic risk scores for the insulin receptor gene network were calculated for the hippocampal (hePRS-IR) and the mesocorticolimbic (mePRS-IR) regions. Cardiometabolic markers included body composition, waist circumference, circulating lipids, insulin-like growth factor 1 (IGF-1), and insulin-like growth factor-binding protein 1 and 3 (IGFBP-1 and -3). Glucose and insulin levels were measured during a standardized 2-hour 75 g oral glucose tolerance test and impaired glucose regulation status was defined by the World Health Organization 2019 criteria. Analyzes were adjusted for population stratification, age, smoking, alcohol consumption, socioeconomic status, chronic diseases, birth weight, and leisure-time physical activity. Multinomial logistic regression indicated that one standard deviation increase in hePRS-IR was associated with increased risk of diabetes mellitus in all participants (adjusted relative risk ratio, 1.17; 95% confidence interval, 1.01 to 1.35). In women, higher hePRS-IR was associated with greater waist circumference and higher body fat percentage, levels of glucose, insulin, total cholesterol, low-density lipoprotein cholesterol, triglycerides, apolipoprotein B, insulin, and IGFBP-1 (all P≤0.02). The mePRS-IR was associated with decreased IGF-1 level in women (P=0.02). No associations were detected in men and studied outcomes. hePRS-IR is associated with sex-specific differences in cardiometabolic risk factor profiles including impaired glucose regulation, abnormal metabolic markers, and unfavorable body composition in women.

BackgroundAngelman syndrome (AS) is a rare neurodevelopmental disorder characterized by severe intellectual disability, little to no expressive speech, visual and motor problems, emotional/behavioral challenges, and a tendency towards hyperphagia and weight gain. The characteristics of AS make it difficult to measure these children’s functioning with standard clinical tests. Feasible outcome measures are needed to measure current functioning and change over time, in clinical practice and clinical trials.AimOur first aim is to assess the feasibility of several functional tests. We target domains of neurocognitive functioning and physical growth using the following measurement methods: eye-tracking, functional Near-Infrared Spectroscopy (fNIRS), indirect calorimetry, bio-impedance analysis (BIA), and BOD POD (air-displacement plethysmography). Our second aim is to explore the results of the above measures, in order to better understand the AS phenotype.MethodsThe study sample consisted of 28 children with AS aged 2–18 years. We defined an outcome measure as feasible when (1) at least 70% of participants successfully finished the measurement and (2) at least 60% of those participants had acceptable data quality. Adaptations to the test procedure and reasons for early termination were noted. Parents rated acceptability and importance and were invited to make recommendations to increase feasibility. The results of the measures were explored.ResultsOutcome measures obtained with eye-tracking and BOD POD met the definition of feasibility, while fNIRS, indirect calorimetry, and BIA did not. The most important reasons for early termination of measurements were showing signs of protest, inability to sit still and poor/no calibration (eye-tracking specific). Post-calibration was often applied to obtain valid eye-tracking results. Parents rated the BOD POD als most acceptable and fNIRS as least acceptable for their child. All outcome measures were rated to be important. Exploratory results indicated longer reaction times to high salient visual stimuli (eye-tracking) as well as high body fat percentage (BOD POD).ConclusionsEye-tracking and BOD POD are feasible measurement methods for children with AS. Eye-tracking was successfully used to assess visual orienting functions in the current study and (with some practical adaptations) can potentially be used to assess other outcomes as well. BOD POD was successfully used to examine body composition.Trial registrationRegistered d.d. 23-04-2020 under number ‘NL8550’ in the Dutch Trial Register: https://onderzoekmetmensen.nl/en/trial/23075

Influence of motor capacity of the lower extremity and mobility performance on foot plantar pressures in community-dwelling older women

ObjectivesTo investigate the associations of motor capacity of the lower extremity and mobility performance in daily physical activities with peak foot plantar pressures during walking among older women. MethodsUsing the data collected among 58 community-dwelling older women (68.66 ± 3.85 years), Pearson correlation and multiple linear regression analyses were performed to analyze the associations of motor capacity of the lower extremity (the 30-s chair stand test, the timed one-leg stance with eyes closed, and the Fugl-Meyer assessment of lower extremity), mobility performance in daily physical activities (the average minutes of moderate to vigorous physical activity every day and the metabolic equivalents), and foot plantar pressures (peak force and peak pressure) with the age and body fat percentage as covariates. Results(1) The motor capacity of the lower extremity has higher explanatory power for peak foot plantar pressures compared with the mobility performance in daily physical activities. (2) Higher body fat percentage was positively associated with peak force and pressure, while a lower score on the Fugl-Meyer assessment of lower extremity was negatively associated with both of them. (3) The metabolic equivalents were positively associated with the peak force, while the 30-s chair stand test was negatively associated with it. ConclusionsMobility performance in daily physical activities can be significant predictors for peak foot plantar pressures among older women. The significant predictor variables include the Fugl-Meyer assessment of lower extremity, the 30-s chair stand test, and metabolic equivalents.

Evaluation of body fat percentage in healthy adults with changes in kidney function

Introduction: Obesity is a pathology with multifactorial etiology. A high percentage of body fat favors the development of numerous comorbidities such as chronic kidney disease (CKD). This work aims to evaluate the percentage of fat in healthy adults with changes in kidney function. Methods: the sample consisted of participants of both sexes, aged 18 years or over. Data collection was carried out through a questionnaire with sociodemographic questions and lifestyle habits, and measurement of anthropometric measurements and blood pressure. For statistical analysis, SPSS software version 19.0 was used. Results: The sample consisted of 244 participants, 76.2% (n=186) were female and 23.8% (n=58) were male. The average age was 46.14 ± 15.19 years. 56.6% (n=138) are healthy adults and 43.4% (n=106) have changes in renal function. The variables weight, WC and WC presented higher mean values in the renal group in relation to the group of healthy adults, and the variables age, BMI, WHtR, Cpes, SBP and DBP presented a higher median value. Finally, there was a high prevalence of altered BF% in the renal group in relation to the control (healthy group). Conclusion: based on the results obtained, the importance of monitoring the nutritional status of patients with CKD is confirmed, in order to maintain an adequate nutritional status, control metabolic changes and control the progression of kidney damage, providing a better quality of life for these patients. population.
