Active clinical trials for "Overweight"

The primary objective of MEDEA is to compare the effect of a personalised telephone-based health education weight loss program based on motivational coaching, exercise and diet versus a standard health educational program control on fatigue of overweight or obese BC patients (as measured by the EORTC QLQ C30 (Aaronson et al. 1993; Sprangers et al. 1996))

According to statistics from the European Association for the Study of Obesity (EASO), taking into account the definition of overweight and obesity recommended by the International Obesity Task Fort (IOTF), the prevalence of overweight (including obesity) in European children aged 7 to 17 years is 16-22% and the prevalence of obesity is 4-6%. Some review studies3 and meta-analysis4,5 have reported an inverse relationship between dairy products consumption and the prevalence or incidence of overweight and obesity. However, some methodological issues arise from these analyses. For instance, the combination of studies with different exposures (e.g. full fat milk, total milk) in the total dairy product analysis. Moreover, since the publication of the lasts meta-analysis in 2016, new epidemiological studies evaluating the association between dairy product consumption and overweight or obesity risk have been published. Objective The aim of this work is to systematically review and assess the associations between total dairy consumption and its different subtypes with the prevalence and incidence of overweight and obesity in children and adolescents.

The main purpose of the clinical trial is to determine the health impact of a dietary intervention known as time-restricted eating (TRE) in patients with metabolic syndrome (defined as the presence of elevated fasting plasma glucose and two or more of the following criteria: increased waist circumference, elevated fasting plasma triglycerides, reduced high-density lipoprotein-cholesterol, elevated blood pressure) and self-reported dietary intake of ≥14 hours per day. Participants will reduce the amount of time they eat to 10 hours per day over a 12-week monitored intervention followed by a 12-week self-directed intervention and will log their dietary intake using a smartphone application (myCircadianClock (mCC) app). Glucose homeostasis (blood glucose levels will be monitored continuously for 2 weeks at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention using a continuous glucose monitor), and other metabolic, neuroendocrine, inflammatory and oxidative stress/antioxidant defense biomarkers, body weight and composition, blood pressure, heart rate, sleep and activity (using mCC app), personal sense of wellness and dietary timing (using health questionnaires) will be evaluated at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention.

The COVID-19 lockdown has represented an unedited model of increased metabolic risk in all age groups, due to negative changes in dietary habits, physical activity, lifestyle. These effects have been generally explored at a population level in distinct age groups. Potential intra-familial, specific effects in adults and children sharing the same socio-economic, cultural level and living habits have been scarcely explored. The investigators aimed to extend the previous observations concerning anthropometric data at the intra-familial level. In particular, The investigators prospectively characterized the variations in lifestyle habits and related outcomes over a 2 two months COVID-19 lockdown period, exploring both parents and their children. A cohort of 149 couple parent/children were prospectively enrolled. By a validated questionnaire The investigators explored changes of Body Mass Index (BMI) and individual lifestyle during a 2-month lockdown.

The investigators hypothesize that compared to the provision of population-based lifestyle advice, providing DNA-based lifestyle advice via personalized nutrigenomics testing (PNT) to two distinct patient populations (Family Health Team patients receiving a lifestyle counselling intervention and transplant recipients) will lead to greater reductions in percent body fat. In addition, it will motivate them to adopt healthier dietary and physical activity habits through changes in attitudes and/or subjective norms and/or behavioural control, lead to greater fat loss (kg), increased percent lean mass and therefore improve health and quality of life outcomes for both patient populations. In addition, it is hypothesized that dietary strategies related to the intake of one or more dietary components of interest will mitigate post-transplant weight gain associated with three SNPs of interest. This is a randomized clinical intervention trial involving a total of four groups of patients (n = 400). The two main patient groups include overweight or obese, stable transplant recipients and overweight or obese patients who are attending group counselling sessions at the East Elgin Family Health Team. Within these two main groups, there will be two sub-groups. Patients will be randomized to receive either PNT or standard nutrition intervention (SNI). Baseline data will be conducted consisting of a food frequency questionnaire and three-day food records using a validated multiple pass method. Bioelectrical Impedance Analysis (BIA) will be conducted to assess body composition and to derive percent body fat and lean mass. Weight and height will be measured using a weigh scale and stadiometer. Attitudes, subjective norms and behavioural control will be assessed using a Theory of Planned Behaviour Questionnaire. Those patients randomized to the PNT group will be instructed on a tailored nutrition care plan and physical activity recommendations based on their individual genetic profile. At the same time, the SNI group will be instructed on general nutrition and physical activity recommendations for weight loss, which include the use of dietary strategies from the standard tool ('Just the Basics') used by registered dietitians for transplant patients and the GLB program for patients attending the East Elgin Family Health Team sessions. Monthly email reminders or phone calls (depending on patient preference) will be sent to transplant recipients as a reminder of their nutrition and physical activity plan. Reminders of nutrition and physical activity goals for the Family Health Team participants are incorporated into the GLB program. Three months, six months and twelve months after baseline data collection and individual nutrition interventions, baseline data will be repeated. After the study is complete, participants in the SNI group will be offered a nutrigenomics report and consultation with a registered dietitian. A paired t-test or repeated measures ANOVA will be used to assess within group change from baseline to each follow-up time point for: BMI, body fat, lean mass, and dietary intake. A repeated measures ANOVA will be used to test between group differences from baseline to each follow-up time point for: BMI, body fat, lean mass, and dietary intake. If significant mean differences are detected, a Tukey's post hoc test will be used to compare differences by group. Statistical significance will be determined by P < 0.05. General linear regression models will be used to assess interactions between each genotype of interest and each dietary component of interest on BMI and body composition from baseline to each follow-up time point.

1.Objective The investigators aim to determine the effect of brisk walking prescription (> 10000 steps, > five days, per week) on body components and metabolic risk factors among patients with overweight/obesity. The objectives are as follow: The body components changes before/after the brisk walking prescription (> 10000 steps, > five days per week) intervention in overweight/obesity population; The metabolic risk factors changes before/after the brisk walking prescription (<10000 steps or <five days per week) intervention in overweight/obesity population 2.Study design This study is a prospective 4-month follow-up scheme in which patients were treated with the following intervention: > 10000 steps, > five days, per week. For individual follow-up, body components and metabolic risk factors will be tested before and after the study. Every participants will be followed up in community visits every month. 3. Statistical analysis Statistical analysis will be performed using SPSS 16.0 version package (SPSS Inc., Chicago, IL.). Numerical data will be presented as mean ± standard deviation for normal distribution or otherwise median (interquartile range). Two-sided independent t-test is adopted for between-group comparison on end-points with normal distribution, otherwise non-parametric test. Row-Column table will be analyzed through chi-square test. P<0.05 is taken as statistical significant.

The effect of overweight and obesity on IVF outcomes is still questionable. The purpose of this study was to determine if overweight/obesity in women with PCOS were associated with an adverse IVF outcome compared to those with normal weight. Design: Retrospective cohort study.

The main aim of this study is to evaluate the bioavailability of blackberry juice anthocyanins, with or without ethanol, in normal weight and overweight/obese adults.

There are an increasing number of individuals in the United States with obesity, and this is a major health concern with links to many chronic diseases. Impairments in protein metabolism with obesity may disrupt muscle function and modify the dietary protein requirements in obese individuals. Further, overweight and obese type 2 diabetics exhibit dramatically reduced skeletal muscle mass compared with lean, healthy controls. Surprisingly, the influence of being overweight or obese on this decline in muscle mass remains understudied, despite clear evidence that similar metabolic impairments typically exist in these populations prior to the development of overt diabetes. Protein ingestion provides the amino acid building blocks to synthesize and repair muscle proteins in adults. Previous research has shown that the muscle protein synthetic response to food ingestion may be reduced in overweight/obese adults. However, this research provided the 'free' amino acids in small portions every 15 min during the postprandial period. In free living conditions, however, it is more common to consume protein dense foods in single portions. Currently, there is no information available on how eating protein rich foods affects muscle protein synthesis in overweight and obese adults. This proposed research will fill this research gap by being the first study to compare the muscle protein synthetic response to the ingestion of a meal-like amount of high quality protein in lean, overweight and obese adults. The objective of this study is to determine the muscle protein synthetic response after the consumption of 35g pork protein in lean, overweight and obese adults. In order to assess this objective the researchers propose to use primed continuous infusion of L-[ring-13C6] phenylalanine to measure muscle protein synthesis rates after the consumption of dietary protein. In a parallel design the researchers will study 13 obese (BMI 30-39.9 kg/m2) participants, 13 overweight (BMI 25-29.9 kg/m2), and 13 age-matched lean controls (BMI 18-24.9 kg/m2) between the ages of 20 and 45 years. All subjects will be sedentary and weight stable for the previous 6 months. On the test day, subjects will remain sedentary for the determination of muscle protein synthesis in both the fasted state and after consumption of the protein meal. Blood and muscle sampling will occur on the test day.

This study tests whether different physical activity patterns are linked an individual's genes.
