Efficacy of a Persian Herbal Remedy and Electroacupuncture on Metabolic Profiles and Anthropometric Parameters in Women with Polycystic Ovary Syndrome: A Randomized Controlled Trial.

Background: The most prevalent endocrine disorder in women of reproductive age is polycystic ovary syndrome (PCOS). The purpose of this study was to evaluate the efficaciousness of a Persian herbal remedy, as well as electroacupuncture and the combination of them on metabolic profiles and anthropometric parameters in these patients. Materials and Methods: Eighty overweight women with PCOS were randomly divided into four groups. All of them received metformin 1000 mg and the second group received 5 g of herbal medicine per day (main components: Foeniculum vulgare, Urtica dioica, and Daucus carota), the third group were subjected to 20 electroacupuncture sessions, and the fourth group received both therapies. Results: After 12 weeks, the body fat and body mass index decreased the most in the herbal medicine+electroacupuncture group, and waist to hip ratio decreased the most in the electroacupuncture group. A significant decrease was also observed in fasting insulin, homeostasis model assessment of insulin resistance. A significant increase was seen in the quantitative insulin sensitivity check index in all intervention groups, but there was no noteworthy difference in these parameters in the control group. Total cholesterol and low-density lipoprotein cholesterol decreased significantly in the electroacupuncture groups and herbal medicine+electroacupuncture. Also, a significant decrease was observed in triglycerides, aspartate aminotransferase, and alanine aminotransferase in the herbal medicine groups and herbal medicine+electroacupuncture. Conclusion: It is advisable to use this herbal remedy and electroacupuncture for better treatment of metabolic complications and overweight problems in these patients.

Effects of exercise training at lactate threshold and detraining for 12 weeks on body composition, aerobic performance, and stress related variables in obese women.

The purpose of this study was to investigate the effect of diet plus exercise training and detraining for 12 weeks on body composition, aerobic performance, and stress-related variables in obese women. Twenty-five women in their 20s-40s with 30% body fat and body mass indices above 25 kg/m2 were divided into HRLT (heart rate at lactate threshold) and HRLT + 5% groups. Dietary intervention of 70% recommended dietary allowance (RDA) and exercise treatment composed of aerobic exercises on a bicycle (30 min) and treadmill (30 min) were then performed. These interventions were performed three times a week for 12 weeks. Dietary intake was significantly decreased, while daily activity significantly increased within the 12-week intervention period, and this effect was sustained after 12 weeks of detraining. Exercise training based on dietary intake and daily activity presented a significantly decreased weight and % body fat, improvement of aerobic performance, and a significant increase in heart rate variability (HRV) (e.g., average of all RR intervals and the square root mean squared differences of successive RR intervals) as stress-related variables. It was also confirmed that the improvement of body composition and stress-related variables were maintained even after detraining. Our results suggest that 70% RDA of dietary intervention and exercise training corresponding to HRLT and HRLT + 5% for 12 weeks were effective in improving body composition and aerobic performance, and relieving stress. In particular, enhanced HRV persisted for up to 12 weeks after the end of exercise training in obese women.

Association of predicted lean body mass and fat mass with cardiovascular events in patients with type 2 diabetes mellitus.

Previous studies have found that predicted fat mass and lean body mass may act differently on adverse events. However, the cardiovascular prognostic value of lean body mass and fat mass in patients with type 2 diabetes mellitus (T2DM) has not yet been investigated. We sought to investigate the relation between predicted lean body mass or fat mass and the risk of cardiovascular disease in patients with T2DM. We conducted a post hoc analysis of data from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study to investigate the relation between the predicted lean body mass or fat mass and major adverse cardiovascular events in patients with T2DM. We used sex-specific quartiles of predicted lean body mass index (BMI; kg/m2) and fat mass index (kg/m2). We defined a major adverse cardiovascular event as a composite of nonfatal myocardial infarction, nonfatal stroke or death from cardiovascular causes. After a mean follow-up period of 8.8 years, we found that a major cardiovascular event occurred in 1801 of 10 251 patients (17.8%). Predicted lean BMI was not associated with major cardiovascular events (p = 0.34). Compared with patients in the first quartile (incidence rate 16.4%; 17.2%, 17.5% and 19.8% for the second, third and four quartiles, respectively) of predicted fat mass index, those in the fourth quartile had a hazard ratio of 1.53 (95% confidence interval 1.23-1.91). In patients with T2DM, we found that predicted fat mass had a strong positive association with a higher risk of a major adverse cardiovascular event. Increasing lean body mass did not have a protective role. Trial registration: ClinicalTrials.gov., no. NCT00000620.

Relations Between Frequency and Volume of Leisure-Time Physical Activity and Body Composition in Police Officers

ABSTRACTPurpose: Leisure-time physical activity (LTPA) has always been very important for the maintenance and improvement of body composition. Thus, the aim of this study was to examine if the frequency and volume of LTPA (F-LTPA and V-LTPA) were related to indices of body composition in police officers. Method: A physical activity questionnaire was used to collect data from 346 male police officers regarding their F-LTPA and V-LTPA. They were divided into four groups relative to the frequency, and four groups relative to the volume of LTPA, labeled as inactive, seldom active, moderately active and very active for each LTPA indicator. Percent body fat (PBF), skeletal muscle mass (PSMM), skeletal muscle mass index (SMMI) and body fat mass index (BFMI) were assessed. Correlation analyses investigated associations and multivariate analysis of variance analysed the differences between body composition and LTPA, with significance set at p < .05. Results: The F-LTPA correlated (p < .001) to PBF (r = −0.306), BFMI (r = −0.289), PSMM (r = 0.309) and SMMI (r = −0.138, p = .010). The V-LTPA correlated (p < .001) to PBF (r = −0.370), BFMI (r = −0.348), PSMM (r = 0.311), and SMMI (r = −0.106, p = .049). The differences that occurred between more and less active police officers, whereby those who were very active had lower values of PBF and BFMI and higher values of PSMM and SMMI regardless of the frequency and volume of LTPA. PBF and PSMM were more affected by LTPA than SMMI and BFMI. Conclusions: F-LTPA and V-LTPA were considered important for police officers, whereby F-LTPA was related to muscle and V-LTPA to fat parameters of body composition.

Body weight, body composition and survival after 1 year: follow-up of a nutritional intervention trial in allo-HSCT recipients

The role of body weight change in survival among recipients of hematopoietic stem-cell transplantation is controversial. We assessed the effect of optimizing energy and protein intake on 1-year survival, body weight and body composition, and the effect of body weight and body composition on 1-year survival in 117 patients (57 intervention, 60 control) in a randomized controlled trial. Cox regression was used to study effects of the intervention, weight and body composition on death, relapse, and nonrelapse mortality (NRM). We found no significant effect of intervention versus control on death hazard ratio (HR) 1.05, 95% confidence interval (CI) 0.54−2.04, p = 0.88), relapse (HR 1.15, 95% CI 0.48−2.27, p = 0.75), and NRM (HR 0.95, 95% CI 0.39−2.28, p = 0.90). Body weight, fat-free mass index, body fat mass index and total body water changed over time (p < 0.001), similarly in both groups (0.17 ≤ p ≤ 0.98). In multivariable analyses adjusted for group, gender and age, HRs and 95% CIs per one kilo increase in weight were 1.03 (1.01−1.06) and 1.04 (1.01−1.08) for death and NRM after 1 year (p ≤ 0.02), respectively, and 1.08 (1.01−1.15) for relapse after 3 months (p = 0.02). In conclusion, weight gain is possibly due to fluid retention and is an indicator of a complication in HSCT, rather than a marker of improved nutritional status.

Alanine Aminotransferase and Body Composition in Obese Men and Women.

There is a known relationship between serum alanine aminotransferase (ALT) and obesity in humans, but the mechanism(s) are not clarified. This study investigated the associations between serum ALT and body composition in an overweight and obese population. The results are based on data from a previous randomized controlled trial treating obesity with vitamin D3. A sample of 448 overweight and obese individuals underwent dual-energy X-ray absorptiometry (DEXA) and measured serum ALT along with supplementary blood samples at study baseline. Body fat mass and lean mass indexes were calculated by dividing total body fat/lean weight (kg) by body height squared (kg/m2). ALT correlated with body mass index (BMI) in men but not women (r = 0.33, P < 0.0001 vs. r = 0.06, P = 0.29). In men, serum ALT correlated positively with fat mass index (r = 0.23, P = 0.004) and lean mass index (r = 0.32, P < 0.0001). In women, ALT correlated with lean mass index (r = 0.13, P = 0.031) but not fat mass index (r = 0.003, P = 0.96). In a multivariate model adjusted for age and fat mass index, a 1-unit increase in lean mass index associated with a 0.37 U/L higher ALT in the male subgroup (95% CI 0.024 to 0.040, P < 0.0001). In conclusion, serum ALT was associated with body fat mass index in men and with lean mass index in men and women in an overweight and obese population. The findings also demonstrate a gender difference in the role of fat.

Geographical differences in osteoporosis, obesity, and sarcopenia related traits in white American cohorts

It has been reported that geographical variation influences bone mineral density (BMD), obesity, and sarcopenia related traits in other countries. However, there is lack of similar studies in the US population. In this study, we compared data from three US study cohorts to evaluate geographical variations of BMD and body composition. BMD, fat mass and lean mass were collected from Dual-energy X-ray absorptiometry machine. ANCOVA and Chi-square tests were used to compare the differences between BMDs, obesity and sarcopenia related traits from different regional sites (Omaha, Kansas City and Baton Rouge/New Orleans). Eta-squared was used to measure the effect sizes of these differences. A total of 11,315 Caucasians from our previous three study cohorts were compared. There was no significant geographical difference in BMD for males or females under the criteria of p-values < 0.05 and effect size η2 > 0.01. There were significant geographical differences with medium effect size (p-value < 0.001, 0.01 < η2 < 0.14) for whole body fat mass percentage and index of low muscle mass. For Caucasians in the United States, there is no significant geographical effect found on BMD. The obesity and sarcopenia related traits are significantly different between the three study cohorts.

Body Composition of Children in the Pre-pubertal and Early-pubertal Period: Are There Some Age-related and Intersexual Differences?

The aim of the presented study was to assess changes in body composition and intersexual differences among children at pre-pubertal and early-pubertal age. The research was designed as a non-randomized cross-section study. The screened sample consisted of 136 girls and 212 boys assigned into three groups according to their age. Body composition was measured using a direct segmental multi-frequency bioelectrical impedance analysis (DSM-BIA). To examine the association between obesity and selected health-related parameters, Kruskal-Wallis ANOVA and Eta2 were used. For evaluation of intersexual differences, Mann-Whitney U-test was used. The presented article is the part of VEGA 1/0840/17 project. From the perspective of age, neither in the group of girls nor boys we recorded any differences in indicators of body composition, namely in body fat mass index, body fat percentage and, in addition, in the group of girls in the waist to hip ratio parameter.

The relationship between anthropometric measures and cardiometabolic health in shift work: findings from the Atlantic PATH Cohort Study.

To evaluate the relationship between anthropometric measures and cardiometabolic health in shift workers compared to non-shift workers. A population health study was conducted with 4155 shift workers and 8258 non-shift workers from the Atlantic Partnership for Tomorrow's Health (PATH) cohort. Linear and logistic regression models were used to assess the differences in anthropometric measures (body adiposity) and self-reported cardiometabolic disease outcomes (obesity, diabetes, and cardiovascular disease) between shift workers and non-shift workers. There was a significant increased risk of cardiovascular disease, obesity, and diabetes among shift workers compared to matched controls despite higher levels of physical activity and lower levels of sedentary behaviour. Shift workers were 17% more likely to be obese (95% CI 7-27) and 27% more likely to have diabetes (95% CI 8-51). The strength of this association was demonstrated by also controlling for body mass index and fat mass index. Shift work is associated with obesity, cardiovascular disease, and diabetes despite higher levels of physical activity and lower levels of sedentary behaviour. The association between shift work and cardiometabolic health was independent of body mass index for cardiovascular disease and diabetes, and independent of fat mass index for diabetes.

Indexes of adiposity and body composition in the prediction of metabolic syndrome in obese children and adolescents: Which is the best?

Background and aimThere is no agreement about which index of adiposity and/or body composition is the most accurate in identifying the metabolic syndrome (METS). The aim of our study was to compare the accuracy of the different indexes in order to recognize the most reliable. Methods and resultsWe evaluated 1332 obese children and adolescents (778 females and 554 males), aged 14.4 ± 1.8 yrs, Body Mass Index (BMI) standard deviation scores (SDS) 2.99 ± 0.55, followed at the Istituto Auxologico Italiano, a tertiary center for childhood obesity. For each subject the following indexes were assessed: BMI, BMI SDS, Fat-Free Mass Index (FFMI), Fat Mass Index (FMI), Tri-Ponderal Mass Index (TMI), Waist-to-Height ratio (WtHR) and a new one, the Body Mass Fat Index (BMFI), which normalizes the BMI for percentage of body fat and the waist circumference. Thereafter we calculated for each index a threshold value for age and sex, in order to compare their accuracy, sensitivity and specificity in identifying the METS. There was a good correlation among indexes (p < 0.0001 for all). However, when the area under the curve (AUC) was compared, some of them, in particular the BMFI and the BMI, performed better than the other ones, although the differences were small. ConclusionsBMI, which neither considers body composition nor fat distribution, performs as good as other indexes, and should therefore be the preferred one, also because of the easiness of its calculation.

Prognostic value of body composition on recurrence and survival of advanced-stage head and neck cancer

BackgroundHead and neck squamous cell carcinoma (HNSCC) is commonly associated with a high risk of malnutrition and sarcopenia, related to adverse clinical outcomes. This study evaluated the prognostic values of body composition on recurrence and survival in patients with advanced-stage HNSCC. MethodsThis study prospectively enrolled 258 consecutive patients with definitive treatments for advanced-stage HNSCC. For the determination of sarcopenia, the cross-sectional area of the skeletal muscles (SMs) was measured at the level of the third lumbar vertebra on the computed tomography images of whole-body 18F-fluorodeoxyglucose positron-emission tomography/computed tomography before and after treatments. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify the prognostic factors of disease-free survival (DFS) and overall survival (OS). ResultsPretreatment and post-treatment diminished SM masses (sarcopenia) were found in 17 (6.6%) and 32 (12.4%) of 258 included patients, respectively. All values of body composition, SM index, visceral fat area, lean body mass, fat mass and body mass index significantly decreased after treatment (all P < 0.05). Multivariable analyses showed that age, Charlson comorbidity index, pretreatment and post-treatment sarcopenia, pretreatment hypoalbuminaemia, p16 status and tumour site remained the independent variables predictive of DFS and OS outcomes (all P < 0.05). Patients with sarcopenia before or after treatment had about threefold increased risk of overall recurrence or death. ConclusionDiminished SM mass may predict recurrence and survival after definitive treatments in patients with advanced-stage HNSCC.

A Cross-Sectional Evaluation of Wellness in New York City Community-Dwelling Seniors (P01-035-19)

ObjectivesThe older adult population is increasing worldwide, placing significant burden on healthcare and support systems. Meeting nutrition and physical activity guidelines is critical to maintain health and quality of life (QOL). The objective of this study was to assess nutrition, swallowing, body composition, and physical function in community-dwelling seniors (CDSs) and describe the prevalence of poor status. MethodsCDSs (n = 54; 42 female; age = 80.1 ± 6.7; body mass index [BMI] = 25.2 ± 4.1 kg/m2) participated in a wellness visit to assess a) nutrition (Dietary Screening Tool [DST], an instrument that identifies nutritional risk), b) swallowing (90 ml water swallow challenge; EAT-10 swallowing screening tool) c) body composition (waist circumference; calf circumference; body fat mass index [BFMI]; fat-free mass index [FFMI]), and d) physical function (SARC-F, a five item sarcopenia screener; Short Physical Performance Battery [SPPB], testing balance, gait speed, and sit to stand). Height was measured using a portable stadiometer; weight with a Seca digital scale. Waist and calf circumferences were measured in triplicate. Body composition was assessed via bioelectrical impedance analysis using the Quad Scan 4000 multifrequency analyzer (BodyStat). BFMI (fat mass, kg/[height, m]2) and FFMI (fat-free mass, kg/[height, m]2) were determined. ResultsThe DST revealed that 11(20.4%) and 35(64.8%) of the CDSs were “at risk” and “possible risk” for poor nutritional status, respectively. Although the EAT-10 documented swallowing difficulties in 5(9.3%) of the CDSs, 12 (22.2%) failed the 90 ml water swallow challenge, consistent with risk of swallowing impairment. Excess adiposity was found in 31(57.4%) using waist circumference and 30(55.6%) using BFMI. Low muscle mass, captured by FFMI, was found in 35(64.8%) of the CDSs. Calf circumference values revealed malnutrition in 3(5.6%) of the CDSs. Six (11.1%) of the CDSs had SARC-F scores associated with poor physical function indicating significant muscle loss in aging. Similarly, SPPB results revealed 14(25.9%) had poor lower extremity physical function. ConclusionsCDSs exhibit impairments in these measures of wellness, placing their health and QOL at risk. Research examining the impact of lifestyle interventions on these measures is needed. Funding SourcesNone

Early life socioeconomic status moderates associations between objective sleep and weight-related indicators in middle childhood

ObjectivesThis study tested whether early socioeconomic status moderated links between objective and subjective sleep and weight indicators during middle childhood. DesignThe study design was cross-sectional but included data from earlier assessment points in the study. SettingData were collected from families across the state of Arizona. ParticipantsParticipants were 382 children recruited from birth records (49.5% female; Mage = 8.47 years; 56.5% European American; 25.1% Latino; 25% living at or below the poverty line). MeasurementsAssessments included socioeconomic status at 12 months of age, and sleep and weight indicators at 8 years. ResultsLonger sleep durations predicted lower body mass index and decreased odds of being overweight/obese across all children, regardless of socioeconomic background. For children from low socioeconomic backgrounds, longer sleep duration predicted lower percent body fat, greater efficiency predicted lower percent body fat and body mass index and smaller waist circumference, and more sleep problems predicted larger waist circumference. For children from low socioeconomic backgrounds, greater sleep duration and efficiency also predicted the lowest odds of being overweight/obese, and more sleep problems predicted the greatest odds of being overweight/obese. ConclusionsEarly life may be a sensitive period that sets the stage for stronger links between sleep and weight indicators in middle childhood. Findings offer important information regarding the protective role of sleep in the promotion of health, as well as the negative consequences that may be stronger for children who experienced low early-life socioeconomic status.

Effects of different exercise training programs on body composition: A randomized control trial.

We aimed to investigate the effects of different exercise training programs on body composition parameters in sedentary middle-aged adults. A total of 89 middle-aged adults (53.5±4.9years old; ~53% women) participated in the FIT-AGEING study. A 12-week randomized controlled trial was performed with a parallel group design. The participants were randomly assigned to (a) a concurrent training based on physical activity recommendation from the World Health Organization group (PAR group), (b) a high-intensity interval training group (HIIT group), and (c) a high-intensity interval training group adding whole-body electromyostimulation group (WB-EMS group). A significant decrease of fat body mass, fat body mass index, and visceral adipose tissue was observed in all training modalities compared to the control group (all P≤0.001). There was a significant increase in lean body mass in the HIIT group as well as in the WB-EMS group compared to the control group and the PAR group (all P≤0.044), whereas an increment of lean body mass index was only observed in the WB-EMS group compared to the control group and the PAR group (all P≤0.042). A significant increase of bone mineral content was observed in the WB-EMS group compared to the control group (P=0.015), while no changes were found in the PAR group and in the HIIT group compared to the control group (all P≥0.2). Our findings suggest that PAR, HIIT, and WB-EMS can be used as a strategy to improve body composition parameters, obtaining slightly better results with the application of WB-EMS.

Fat and fat-free mass of healthy Swedish children show tracking during early life, but there are differences.

Obesity may start early in life. We investigated relationships between size and body composition variables in infancy and at 4years of age using valid estimates of body composition. The results were compared to those obtained when body mass index (BMI) was used to estimate body fatness at 4years. Using air displacement plethysmography, size, fat mass and fat-free mass were studied, between 2007 and 2015, in 253 full-term healthy Swedish children at 1week, 12weeks and 4years of age. Positive associations between variables in infancy and at 4years were found at 1 and 12weeks for weight, height, BMI, fat-free mass and fat-free mass index (p≤0.002) and for fat mass, per cent body fat and fat mass index (p≤0.04) at 12weeks. Fat mass gained during infancy correlated positively (p≤0.031) with per cent fat mass, fat mass index and BMI, all at 4years. In girls, gains in fat-free mass during infancy correlated with BMI (p=0.0005) at 4years. The results provide information regarding body composition trajectories during early life and demonstrate limitations of BMI as a proxy for body fatness when relating early weight gain to variables, relevant for later obesity risk.

Rural‐Urban Disparities in Total Physical Activity, Body Composition, and Related Health Indicators: An Atlantic PATH Study

To describe and compare the sociodemographic and lifestyle characteristics of urban and rural residents in Atlantic Canada. Cross-sectional analyses of baseline data from the Atlantic Partnership for Tomorrow's Health cohort were conducted. Specifically, 17,054 adults (35-69 years) who provided sociodemographic characteristics, measures of obesity, and a record of chronic disease and health behaviors were included in the analyses. Multiple linear regression and logistic regression models were used to calculate the multivariable-adjusted beta coefficients (β), odds ratios (OR), and related 95% confidence intervals (CI). After adjusting for age, sex, and province, when compared to urban participants, rural residents were significantly more likely to: be classified as very active (OR: 1.19, CI: 1.11-1.27), be obese (OR: 1.13, 1.05-1.21), to present with abdominal obesity (OR: 1.08, CI: 1.01-1.15), and have a higher body fat percentage (β: 0.40, CI: 0.12-0.68) and fat mass index (β: 0.32, CI: 0.19-0.46). Rural residents were significantly less likely to be regular or habitual drinkers (OR: 0.83, CI: 0.78-0.89). Significant differences remained after further adjustment for confounding sociodemographic, lifestyle, and health characteristics. No significant differences in smoking behavior, fruit and vegetable intake, multimorbidity, or waist circumference were found. As expected, obesity prevalence was higher in rural Atlantic Canadians. In contrast to much of the existing literature, we found that rural participants were more likely to report higher levels of total physical activity and lower alcohol consumption. Findings suggest that novel obesity prevention strategies may be needed for rural populations.

Changes of body composition, physical fitness, and blood variables according to the short-term weight reduction in college ssireum athletes.

The purpose of the study was to investigate the influence of short-term weight loss on body shape, physical fitness, and blood variables in college ssireum (one of the Korean traditional martial art) athletes. Six college ssireum athletes participated as subjects. The weight loss program includes 50% of limited diet, 5.5 hr of physical and skill training. Body composition such as weight, body fat, muscle mass, and body mass index (BMI) was determined. Fitness test such as shuttle run, sit-up, trunk extension test, grip test, sitting reach test, and side step test was measured. Blood variables such as total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein, glucose, reactive oxygen species (ROS), malondialdehyde (MDA), and superoxide dismutase (SOD) were checked before and after the short-term weight reduction. The results revealed significant decrease in body composition such as weight, body fat, muscle mass, and BMI. Fitness test also showed significant decrease in sit-up, trunk extension test, and grip test. The results demonstrated positive significant change in side step test, shuttle run, and sitting reach test. The results of blood variables showed significant decrease in total cholesterol, LDL, glucose and SOD. In contrast, MDA revealed significant increase and no significant change was found in ROS. Finally, it is assumed that a proposal of weight loss without decrease of muscle mass, muscle force, and muscle endurance is necessary because of the negative effects on muscle force and muscle endurance which should be used during actual games.

Diet Quality Is an Indicator of Disease Risk Factors in Hispanic College Freshmen

BackgroundNo studies have assessed the relationship between diet quality, using the Healthy Eating Index (HEI), and adiposity, physical activity, and metabolic disease risk factors in a Hispanic college population. ObjectiveTo assess associations between diet quality and adiposity, metabolic health, and physical activity levels in a Hispanic college freshman population. DesignThis was a cross-sectional study. Measurements were obtained during a 4-hour in-person visit and included demographic information via questionnaire, height, weight, waist circumference, body mass index, body fat via BodPod, hepatic fat, visceral adipose tissue (VAT) and subcutaneous adipose tissue via magnetic resonance imaging, glucose, insulin, homeostatic model assessment of insulin resistance (HOMA-IR), and lipids via blood draw from fasting subjects, physical activity (ie, step counts per day and time spent in different intensity levels) via 7-day accelerometry, and dietary intake via three to four 24-hour dietary recalls. Dietary quality was calculated using the HEI-2015. Participants/settingHispanic college freshmen (n=92), 18 to 19 years, 49% male, who were enrolled at University of Texas at Austin from 2014 to 2015. Main outcome measuresMain outcome measures were diet quality and adiposity, metabolic health, and physical activity levels. Statistical analyses performedLinear regressions determined if dietary quality is related to adiposity, metabolic, and physical activity outcomes. A priori covariates included sex, body fat, and body mass index percentile (for metabolic models), and moderate and vigorous physical activity (MVPA, for adiposity and metabolic models). ResultsThe average HEI-2015 total score was 54.9±13.4. A 1-point increase in HEI score was associated with 1.5 mL lower VAT (P=0.013); 8 minutes per day higher light activity (P=0.008), and 107 more step counts per day (P=0.002); and 0.10 μg/mL lower insulin (P=0.046) and 0.5 U lower HOMA-IR (P<0.001). ConclusionResults suggest that small improvements in diet quality may be positively associated with a reduction in metabolic disease risk, during a critical time period in a young person’s life.

Multidisciplinary obesity treatment program improved health-related quality of life and positively correlated with anthropometric and body composition but not with cardiorespiratory fitness parameters in adolescents.

The aim of the present study was to verify the effects of a 16-week multidisciplinary obesity treatment program (MOTP) on health-related quality of life (HRQoL) in adolescents with weight excess. In addition, we verified a possible association between changes on HRQoL and anthropometric, body composition, and cardiorespiratory fitness (CRF) parameters. Two hundred four adolescents aged from 15 to 18years were distributed in control group (CG) and intervention group (IG). They underwent a 16-week MOTP composed by nutritional, psychological, and health-related physical activity group sessions. Moreover, they performed physical exercise sessions three times per week during the whole 16-week program. Data on HRQoL, body composition, CRF and anthropometry were collected using standard protocols and validated questionnaires. The MOTP promoted significant enhancements in all HRQoL domains, except for the school domain in IG. Furthermore, positive correlations between HRQoL and body weight (BW), body fat (BF), waist circumference (WC), and body mass index (BMI) z-score were verified. Higher scores of HRQoL might be achieved by improving these variables. The 16-week MOTP was effective to improve HRQoL in adolescents with weight excess. This improvement has a positive correlation with enhancements in BW, BMI z-score, WC, and BF. Nevertheless, these findings have not reached a consensus on literature and still need to be further enlightened.
