Abstract Objectives Maternal obesity increases the risk for adverse pregnancy and offspring outcomes; however, with large heterogeneity. We hypothesize that in mothers with obesity, the heterogeneity of offspring adiposity is due to prolonged exposure to excess maternal substrates, namely glucose and triglycerides, which promote fetal fat accretion. The aims of this prospective observational study were to 1) examine the maternal metabolic milieu in pregnant women with metabolically unhealthy obesity, MUO and metabolically healthy obesity, MHO; and 2) identify if these maternal metabolic phenotypes in women with obesity influence infant adiposity. Methods During early pregnancy, 51 women with obesity were classified to have MUO (n = 9) or MHO (n = 13) based on the presence of zero (MHO) or ≥ 2 (MUO) risk factors for metabolic syndrome (SBP > 130 or DBP > 85, HDL < 50 mg/dL, LDL ≥ 100 mg/dL, triglycerides ≥ 150 mg/dL, and glucose ≥ 100 mg/dL). Area under the pregnancy concentration curve (AUC) for glucose and triglycerides, gestational weight gain (GWG), fat accretion, and energy intake and expenditure from early (13–16 wks), mid (24–27 wks) to late (35–37 wks) pregnancy and infant fat mass were compared between groups. Results Compared to women with MHO, women with MUO were not different with respect to maternal BMI, GWG, fat accretion, energy and macronutrient intake, and energy expenditure. In both groups, maternal substrates changed similarly from ∼13 to ∼37 weeks of pregnancy, however MUO resulted in greater pregnancy AUC for glucose (+2169.7 ± 381.5 p < 0.001 mg/dL · day) and triglycerides (+12,210.5 ± 3916.1 mg/dL · day, p < 0.001). The offspring of women with MHO had significantly lower birth weight (−620.8 ± 204.6 g, p = 0.01), body fat percentage (−5.8 ± 2.1%, p = 0.02), and total fat mass (−268.8 ± 88.4 g, p = 0.01). Conclusions Differing obesity phenotypes in pregnancy may explain the heterogeneity of offspring adiposity. Metabolically unhealthy obesity resulted in a more prolonged exposure of fetal fat promoting substrates and increased adiposity at birth. This study identifies a population of women with obesity most in need of prenatal interventions and suggests that obesity phenotypes need to be considered when evaluating intervention effect on offspring outcomes.

Abstract Objectives The objectives of this study were to determine if body composition and nutrient status are dependent on serumosteocalcin concentrations in healthy adults. Methods Adults 20 to 70 years of age completed fasting blood sampling to measure serum ionized calcium concentrations, serum ionized magnesium concentrations, and serum total osteocalcin concentrations. Dual Energy X-Ray Absorptiometry was also completed to measure body composition variables including body mass index (BMI), total fat mass, total fat freemass, total lean mass, android fat, gynoid fat, trunk fat, and visceral adipose tissue. Results A sample of 60 women and 78 men with a median age of 33.0 (21.0) years were categorized into two groups accordingto the median osteocalcin concentration measured: low osteocalcin (12.11 ± 2.72 ng/mL), and high osteocalcin (26.80 ± 9.72 ng/mL). Means, standard deviations, medians and interquartile ranges were calculated and independent t-tests, and Mann Whitney U tests were conducted to determine differences between groups in body composition variables. Total fat mass, total fat percentage, android fat, trunk fat, and trunk fat percentage were all significantly higher, and totalfat free mass, fat free mass percentage, total lean mass, lean mass percentage, serum ionized calcium concentrations, and serum ionized magnesium concentrations were all significantly lower (P < 0.05) in the low osteocalcin groupcompared to the high osteocalcin group. There were no differences (P >0.05) between groups in weight, gynoid fat, visceral adiposity tissue, or visceral adiposity tissue percentage. Conclusions The results of this study provide preliminary evidence that serum osteocalcin concentrations can predict bodycomposition. Interventional studies should consider methods to alter osteocalcin concentrations through vitamin ormineral supplementation as a means to improve body composition in adults.

AbstractThe purpose of this study was to examine body composition of National Collegiate Athletic Association Division I female soccer players by position and season. One hundred seventy-five female athletes were categorized by positions of forward (n=47), midfielder (n=51), defender (n=57), and goalkeeper (n=20). A dual X-ray absorptiometry scan assessed percent body fat, total lean mass, total fat mass, arm and leg lean mass and fat mass, and visceral adipose tissue. Goalkeepers had significantly higher total, arm, and leg lean mass and fat mass compared to all other positions (p<0.05). For seasonal changes, body fat percentage was significantly higher in winter off-season (26.7%) compared to summer off-season (25.7%) and pre-season (25.8%; p<0.01) for all positions. Total and leg lean mass was significantly lower in winter off-season compared to all other seasons, and total lean mass was significantly higher in summer off-season than pre-season (p<0.01). Overall, goalkeepers were significantly different than all other positions. Body fat percentage increased and lean mass decreased in winter off-season indicating potential undesired changes in training and/or nutrition over the break whereas lean mass was the highest in summer off-season potentially reflecting the emphasis on resistance training and increased volume of training.

Abstract The aim of this study was to analyze the association between body composition and performance in the karate specific aerobic test (KSAT). This is a study carried out with thirteen athletes (6 females) with a mean age of 20.7 ± 4.2 years, affiliated to the Pernambuco Federation of Karate Associations, were developing this training routine during the 2018 season. Body mass and height were measured. To measure body composition, the body densitometry method was used by the x-ray double-ray absorptiometry (DEXA) technique. Karate Specific Aerobic Test was used to verify aerobic performance. Association analyzes were performed between body composition variables and KSAT performance using Pearson's correlation test and linear regression. All analyzes adopted a significance of p <0.05. KSAT performance was negatively correlated with total fat mass (r = -0.797; p = 0.001) and fat percentage (r = -0.757; p = 0.003). The linear regression model with the highest explanatory power included total fat and KSAT (adjusted R² = 0.732; p <0.001) exhibited a negative association with total fat (? = -0.21; p <0.001), and the model that included % body fat and KSAT (adjusted R² = 0.708; p = 0.003) were negatively associated with% body fat (? = -22.937; p = 0.001), both adjusted for gender and age. There is a negative association between total fat mass, body fat percentage and karate specific aerobic test performance.

BackgroundPuberty is a period of rapid growth associated with metabolic, hormonal, and body composition changes that can influence risk factors for chronic diseases such as type 2 diabetes.ObjectiveTo evaluate body composition and insulin sensitivity (IS) modifications throughout puberty in a large group of obese Caucasian subjects.MethodsFive hundred and nineteen obese subjects (4–19 years), grouped according to gender and Tanner stage (T), underwent oral glucose tolerance test. Quantitative insulin check index (QUICKI) and ISI were calculated as indexes of IS. In 309 subjects, body composition by dual-energy X-ray absorptiometry, IGF1, adiponectin, and leptin were also evaluated.ResultsBody composition modifications were sexually dimorphic, with girls not modifying fat and lean percentage and fat distribution (P>0.15), and boys decreasing fat percentage and increasing lean percentage and central fat depot (P<0.001) across Ts. IS decreased during mid-puberty and returned to prepubertal levels by the end of puberty. Girls showed lower IS than boys (P<0.01 and =0.03 for QUICKI and ISI respectively). In multivariate analysis factors that negatively influenced IS, independently from T or age, were total fat mass and central fat depot in girls (P<0.05 and <0.01, respectively), total fat and lean mass in boys (P<0.01). IGF1, adiponectin, and leptin were not related to pubertal IS.ConclusionsIn obese Caucasian subjects, further decrease of IS observed during puberty is a transient phenomenon. Factors that independently from T or age influence IS are central fat depot in girls, lean amount in boys, and total fat mass in both sexes.

Obesity is caused by fat accumulation. BMI Z-score is used to classify the different degrees of weight status in children and adolescents. However, this parameter does not always express the true percentage of body fat. Our objective was to determine the degree of agreement between the fat mass percentage measured by DXA and the stratification of weight according to BMI Z-score in the pediatric age group. We designed a descriptive cross-sectional study. The patients were classified as underweight/normal weight with Z-scores between −2 and +0.99, overweight from 1 to 1.99, obese from 2 to 2.99, and very obese ≥3. We included 551 patients (47% girls), with a mean age of 11.5 ± 2.8 years (3.7–18 years). Higher BMI Z-scores were associated with a higher percentage of total fat (p < 0.001). However, there were important overlaps between both parameters, such that the BMI Z-score classified patients with the same percentage of total fat mass as having a different nutritional status classification. In conclusion, the stratification of weight status according to BMI Z-score revealed that 46.7% of patients had a fat percentage that did not correspond to their classification. For a more accurate weight assessment in clinical practice, we recommend combining anthropometric indices with diagnostic tools that better correlate with DXA, such as electrical bioimpedance.

The purpose of this study was to analyze the adiposity profile and the body fat distribution in 56 sub-elite female rugby union players involved in the Spanish National Women’s Rugby Union Championships. The participants included in this study, which was the first to analyze sub-elite players, show thinner skinfolds, lower fat mass, and lesser fat percentage than previously reported for elite female rugby union players. Forwards were heavier and had higher body mass index (BMI) and fat mass, thicker skinfolds, and higher fat percentage than back players. Forwards also possessed significantly greater total fat-free mass than backs. All these differences were applicable only to players under 25 years of age. A negative correlation between age and both abdominal and lower extremity fat was found in forward players but not in the backs. Both Yuhasz and Faulkner equations tended to underestimate fat percentage in comparison to Reilly equation. Although Yuhasz equation provided higher systematic error, random error was lower in comparison to Faulkner equation. This study shows the relevance of analyzing and monitoring adiposity in female rugby union players to optimize adaptation to the sports requirements of different playing positions and age.

Abstract Objectives Maternal obesity is strongly associated with offspring obesity risk. However, studies show that paternal obesity also affects offspring phenotype, especially in males. Programming of the growth hormone (GH) insulin-like growth factor (IGF) axis seems to be an important mechanism in this finding, but evidence regarding this relationship in humans is scarce. The primary purpose of this study was to evaluate associations between maternal and paternal adiposity with that of their offspring. A secondary aim was to investigate associations between paternal adiposity with GH levels in male offspring. Methods Parent-offspring trios (n = 209) from the Glowing study were studied. Percent body fat mass (%FM) was measured using air displacement plethysmography early in pregnancy in parents, and at age 2 weeks in the offspring. Plasma GH levels were measured at birth from umbilical cord blood (n = 31) and at age 2 years (n = 39) in male offspring. Multiple linear regression was used to model infant's %FM (dependent variable) at 2 weeks of age using parental %FM, race, age, IQ, income, delivery method, gestational weight gain, feeding mode, and gestational age (GA) as independent variables. The best fitted models were constructed for girls and boys. Spearman correlations (ρ) between paternal %FM and offspring GH levels were adjusted for maternal %FM. Results Girls (n = 94): Paternal %FM did not associate with female newborn %FM. Instead, maternal %FM (β = 0.12, P = 0.010) and C-section delivery mode (β = 2.56, P = 0.011) had the strongest associations with female newborn %FM. Boys (n = 115): Maternal %FM (β = 0.12, P = 0.006) and GA (β = 1.06, P = 0.003) were positively associated with male newborn %FM, whereas paternal %FM was negatively associated (β = −0.09, P = 0.014) with male offspring adiposity. There was no significant correlation between paternal %FM and GH measured at birth (ρ = 0.19, P = NS) in boys. However, at age 2 years, GH levels in boys decreased with increasing paternal %FM (ρ = −0.40, P = 0.015). Maternal %FM did not correlate with offspring GH level at any age. Conclusions Parental obesity differentially associates with newborn girls’ and boys’ adiposity at age 2 weeks. In line with prior findings in animal models, this preliminary analysis points to programming of the GH/IGF axis in male offspring born to obese fathers.

Abstract Background: Essential amino acids (EAAs) promote the process of regulating muscle synthesis. Thus, whey protein that contains higher amounts of EAA can have a considerable effect on modifying muscle synthesis. However, there is insufficient evidence regarding the effect of soy and whey protein supplementation on body composition. Thus, we sought to perform a meta-analysis of published Randomized Clinical Trials that examined the effect of whey protein supplementation and soy protein supplementation on body composition (lean body mass, fat mass, body mass and body fat percentage) in adults. Methods: We searched PubMed, Scopus, and Google Scholar, up to August 2020, for all relevant published articles assessing soy protein supplementation and whey protein supplementation on body composition parameters. We included all Randomized Clinical Trials that investigated the effect of whey protein supplementation and soy protein supplementation on body composition in adults. Pooled means and standard deviations (SD) were calculated using random-effects models. Subgroup analysis was applied to discern possible sources of heterogeneity. Results: After excluding non-relevant articles, 10 studies, with 596 participants, remained in this study. We found a significant increase in lean body mass after whey protein supplementation weighted mean difference (WMD: 0.91; 95% CI: 0.15, 1.67. P= 0.019). Subgroup analysis, for whey protein, indicated that there was a significant increase in lean body mass in individuals concomitant to exercise (WMD: 1.24; 95% CI: 0.47, 2.00; P= 0.001). There was a significant increase in lean body mass in individuals who received 12 or less weeks of whey protein (WMD: 1.91; 95% CI: 1.18, 2.63; P<0.0001). We observed no significant change between whey protein supplementation and body mass, fat mass, and body fat percentage. We found no significant change between soy protein supplementation and lean body mass, body mass, fat mass, and body fat percentage. Subgroup analysis for soy protein indicated there was a significant increase in lean body mass in individuals who supplemented for 12 or less weeks with soy protein (WMD: 1.48; 95% CI: 1.07, 1.89; P< 0.0001). Conclusion: Whey protein supplementation significantly improved body composition via increases in lean body mass, without influencing fat mass, body mass, and body fat percentage.

AbstractNormal weight obesity (NWO) describes individuals who have a normal weight body mass index (BMI), but have an unhealthy amount of body fat. Based on the life-long habits that develop during college, exploring NWO among a college-aged population may be essential in identifying and preventing obesity that develops in early adulthood. This study aimed to characterize NWO among young adults with normal weight BMI. 94 college students (Mean ± SD: Age: 19.6 ± 1.5 yrs; BMI: 21.9 ± 1.8 kg/m2) enrolled during the Fall semester (Aug-Oct) were assessed for body composition by dual energy X-ray absorptiometry to determine body fat percentage, fat mass, lean mass and trunk fat; lifestyle habits were characterized from validated questionnaires. Mean arterial pressure and metabolic biomarkers [total cholesterol, high density lipoproteins, non-high density lipoproteins, and glucose] were evaluated for cardiometabolic health. NWO was defined using data from the National Health and Nutrition Examination Survey (NHANES) for body fat percentage. Data was analyzed by group (NWO vs NWL) and sex. with independent t-tests to investigate continuous data, and chi-square test of independence for categorical data. Rates of NWO for the total sample were 13.8%. Males (n=30) had a higher rate of NWO (26.7%) compared to females (n=64; 7.8%). NWO individuals had higher fat mass (p=0.024), trunk fat (p<0.001), and larger waist to hip ratio (p<0.001) than normal weight lean. NWO also engaged in less vigorous physical activity (p=0.043). The occurrence of NWO among otherwise healthy college students is evident. Identification of these individuals may be an effective component for obesity prevention and treatment. Determining feasible methods to measure body fat in this population is essential, as BMI may mask obesity in a young adult population.
