Effect of Tai Chi and Multimodal Exercise in Overweight and Obese Women

Obesity is a health problem that results from the interaction of genetic, socio-economic, and socio-cultural factors, leading to excessive accumulation of body fat that harms the body and poses a risk to health. Excess weight and obesity negatively affect the musculoskeletal system, leading to limitations associated with physical functionality. In overweight and obese individuals, the musculoskeletal system experiences increased stress on bones, joints, and soft tissues. This causes balance and gait disorders, frequently leading to injuries from falls. Regular exercise is known to play a significant role in regulating energy balance, reducing the risk of obesity-related health problems, and decreasing the morbidity and mortality associated with these problems. However, while the literature shows numerous weight-focused studies on excess weight and obesity, intervention and comparative studies aimed at improving balance ability as a primary goal affecting an individual's physical mobility are limited. Furthermore, studies examining the effects of tai chi and multimodal exercise training on overweight and obese individuals are also limited. In the present study, it is aimed to examine the effects of a 10-week Tai Chi and Multimodal exercise program on balance in overweight and obese women, and to compare the effectiveness of Tai Chi and Multimodal exercises. The results of this study can guide the development of exercise programs to be used in the treatment of obesity and provide a scientific basis for creating more effective and sustainable rehabilitation strategies in the long term.

A Study to Evaluate the Efficacy and Safety of DA-302168S Tablets in Overweight/Obese Subjects

It is a multicenter, randomized, double-blind, placebo-controlled phase II clinical trial to evaluate the safety and efficacy of DA-302168S tablets in overweight and obese adults.

TREAT to Improve Cardiometabolic Health

Over half of American adults have overweight or obesity and are at high risk of developing type 2 diabetes and cardiovascular diseases. Although caloric restriction has many health benefits, it is difficult to sustain overtime for most people. Time restricted eating (TRE), a novel type of intermittent fasting, facilitates adherence to the intervention and results in weight loss and improvement of metabolism. The investigators propose to examine the efficacy of self-monitoring and TRE (10-h/d) vs. self-monitoring and habitual prolonged eating duration (HABIT) (13 hours/d) on weight loss and body composition, metabolic function and circadian biology, in metabolically unhealthy adults aged 50 to 75 y old, with overweight or obesity. The investigators hypothesize that TRE, compared to habitual long duration of eating, will decrease cardiovascular risk burden.

WB-EMS Effects on Cardiometabolic Risk Factors

From the age of 50 onwards, there is a disproportionate decline in muscle strength, mass and function, which can be prevented or at least delayed by physical training. Unfortunately, many training programmes are very time-consuming and strenuous and are therefore not carried out consistently. Whole-body electromyostimulation (WB-EMS), a technology in which all major muscle groups are stimulated with an adjusted stimulation level, could be a time-effective and joint-friendly alternative. However, there are some contraindications to the widespread use of this technology, which are particularly common in middle-aged and elderly people. For example, high blood pressure, which affects more than half of men over the age of 50 in Germany, is considered a contraindication for WB-EMS training. However, this assessment is not very reliable; at least, acute WB-EMS application does not lead to an increase in blood pressure. In addition, there are no study results available for long-term WB-EMS application in people with high blood pressure. The present study particularly investigate whether and to what extent several weeks of WB-EMS training has an effect on resting blood pressure in people with mild blood pressure. Additionally, the effect of WB-EMS on other cardiometabolic risk factors and physical function will be addressed.

Postprandial Inflammation and Nuts (PIN) in Older Adults

The aging population is rapidly increasing, and it is important to identify dietary factors that can prevent disease and promote health in this group. Legumes, such as peanuts, are a plant-based food high in protein and unsaturated fat making this a healthy choice, but are not consumed frequently enough in older adults. Studies have shown that regular nut consumption is associated with lower adiposity and reduced weight gain and inflammation. Given these findings, this study will examine the postprandial effects of meals with 2 levels of saturated fatty acids (SFA) on metabolic endotoxemia, inflammation and satiety, using a randomized cross-over design. The low SFA meal includes peanuts that are high in monounsaturated fatty acids (MUFA) and this will be compared to a high SFA meal. The results of this study have the potential to provide valuable insights into the role of peanuts in promoting health and preventing disease in at-risk older adults.

AI-Driven Metabolic Cohort in Overweight/Obese Chinese Adults

The goal of this observational cohort study is to delineate the five-year dynamic trajectories of metabolic phenotypes in Chinese adults with overweight or obesity, with or without type 2 diabetes, focusing on transition rates from metabolically healthy overweight/obesity to unhealthy overweight/obesity or to type 2 diabetes, as well as the incidence and progression of diabetic complications and cardiovascular events in those with type 2 diabetes and overweight/obesity. Researchers will compare three phenotype groups, namely metabolically healthy overweight/obesity, metabolically unhealthy overweight/obesity, and type 2 diabetes with overweight/obesity, to assess differences in metabolic parameter changes, complication rates, and cardiovascular risk. Participants will use a digital health management platform for data upload and lifestyle support, and will complete comprehensive health assessments at baseline, at 2.5 years, and at 5 years, along with annual light follow-ups.

PRE-Pregnancy Weight Loss And the Reducing Effect on CHILDhood Overweight - Copenhagen

The study is a single site parallel randomized controlled study. The study will be assessing the effect of approximately 10% weight loss intervention vs a control group among healthy females/couples where the prospective mother is overweight or obese (BMI 27-45 kg/m\^2) and between 18-38 years. The investigators will recruit a total of 240 healthy females/couples who will be randomized 1:1 to either intervention or control, stratified according to maternal pre-pregnancy BMI. The overall objective is to test whether a comprehensive pre-conceptional parental weight loss intervention effectively reduces the risk of offspring overweight and adiposity and its complications compared to a control group. The investigators hypothesize that parental weight loss intervention, initiated before conception, will facilitate lower parental insulin resistance, inflammation, body weight and adiposity, incretin responses compared to usual care. For the offspring the investigators hypothesize that the intervention will reduce adverse pregnancy outcomes with a reduction in offspring neonatal adiposity, reduced risk of being born large for gestational age (LGA) and with lower BMI z-score at 12 months.

A Trial to Learn How Safe AZD9550 Monotherapy and Combined With AZD6234 is in People With or Without Type 2 Diabetes Who Are Living With Obesity and Overweight

AZD9550, previously being developed for the treatment NASH, is a dual GCG and GLP-1 receptor agonist. AZD9550 is now being developed in combination with AZD6234, a SARA, for the treatment of overweight and obesity and its associated co-morbidities. Co-administration of AZD9550 and AZD6234 is currently being evaluated in participants living with obesity and overweight without T2DM in an ongoing Phase 2b study. The purpose of this study is to investigate the safety, tolerability, and effects of increasing doses of AZD9550 monotherapy in overweight and obese participants aged 18 through 65 years living with or without T2DM, and to investigate how AZD9550 is absorbed, distributed, and eliminated from the body (Parts A-D). In addition, the study will investigate the safety and tolerability of co-administration of AZD9550 and AZD6234 in participants living with T2DM with obesity or overweight aged 18 through 75 years (Part E), and safety and tolerability for different titration regimens for AZD9550 in participants living with obesity, but without T2DM, aged 18 through 75 years (Part F).

Each site builds on thriving community partnerships, which have been instrumental in enhancing trust, community capacity, and readiness to reduce health disparities.

Healthy Mothers-Healthy Children Nutrition

Using a randomized two-group, repeated measures experimental design, the goal of the proposed study is to investigate the efficacy of a 12-week nutrition and exercise education, physical activity, coping skills training, and home-based physical activity intervention in Hispanic women and their 3-5 year old children and 6 months of continued monthly contact to help overweight and obese Hispanic mothers improve adiposity, weight, health behaviors, and self-efficacy and their 3-5 year old children improve their adiposity and weight gain trajectory and health behaviors.

The Fibre Full Study

This study will systematically investigate the effects of a diet with decreased energy density, reduced glycaemic index, and significantly increased dietary fibre, on post-prandial glycaemic response, satiety, gastrointestinal tolerability and gut microbiota composition and function in individuals with excess body weight (Body Mass Index (BMI) 25-35kg/m2). Hypothesis: The investigators hypothesise that a diet enriched in fibre will be beneficial to post-prandial glycaemic response, well tolerated and satiating, as compared to the standard Western-style diet.

Prognostic Value of SII and SIRI in Obesity-Related Metabolic Complications

This observational study aims to evaluate the diagnostic and prognostic value of the systemic immune-inflammatory index (SII) and the systemic inflammation response index (SIRI) in individuals with overweight or obesity. The study will assess their association with obesity status, metabolic complications, lifestyle patterns, dietary indices, and established inflammatory biomarkers. Participants will undergo anthropometric assessment, laboratory testing, dietary evaluation, and follow-up for response to different obesity treatment modalities over 3 years. The study intends to determine whether SII and SIRI can serve as clinically useful predictors of metabolic risk and treatment outcomes of obesity.

Pregnancy Exercise Mode Effect on Childhood Obesity

The overall objective of this proposal is to conduct a longitudinal prospective study of overweight/obese (OW/OB) pregnant women and their offspring to determine which prenatal exercise mode will have the greatest impact on maternal and infant cardiometabolic health. This information may lead to clinical practice recommendations that improve childhood health. This randomized controlled trial will recruit 284 OW/OB pregnant women randomized to an exercise intervention (aerobic (AE), resistance (RE), or aerobic+resistance exercise (AERE)) or to no exercise; their infants will be measured at 1, 6, and 12 months of age. This design will test our central hypothesis that AERE and RE training during pregnancy will improve maternal and offspring cardiometabolic outcomes to a greater extent than AE alone. This hypothesis will be tested with two specific aims: Aim 1. Determine the influence of different exercise modes during OW/OB pregnancy on infant cardiometabolic health and growth trajectories. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve offspring neuromotor and cardiometabolic measures at 1, 6, and 12 months postpartum (e.g. decreased %body fat, BMI z-score, heart rate \[HR\], non-HDL, and C-Reactive Protein (CRP); increased insulin sensitivity) compared to infants of OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving infant measures. Aim 2. Determine the most effective exercise mode in OW/OB pregnancy on improving maternal cardiometabolic health outcomes. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve both maternal cardiometabolic health measures (e.g. decreased BMI z-score, non-HDL, % body fat, HR, weight gain) across pregnancy (16-36 weeks' gestation) and overall pregnancy outcomes (e.g. lower incidence of gestational diabetes, pre-eclampsia, hypertension during gestation) compared to OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving maternal health measures, with the AERE group having the highest compliance. The proposed study will be the first to provide an understanding of the influence of maternal exercise modes on the cardiometabolic health and growth trajectories of offspring who are at increased risk due to maternal OW/OB. This work will have a significant impact on reducing the cycle of OB, potentially providing the earliest and most efficacious intervention to decrease or prevent OB in the next generation.

ABUNDANCE of A NATURAL ODOUR in HUMAN CEREBROSPINAL FLUID AFTER OLFACTORY EXPOSURE - the OLFO-Brain Study

The goal of this clinical trial is to investigate the abundance of a natural odour in human cerebrospinal fluid in obese and lean participants after inhalation thereof. Participants will undergo blood sample collection and inhalation of either a natural odour or placebo through an inhaler in addition to a liquor puncture prescribed in standard of care context.

Cottonseed Oil Dose Response

Adding cottonseed oil to the diet has been shown to improve cholesterol profiles and other markers of chronic disease risk in both healthy and at-risk adults. However, CSO has only been tested in the context of high-fat diets. The goal of this clinical trial is to learn about the health effects of lower amounts of cottonseed oil (CSO) added to the diet in adults at increased risk for cardiovascular disease. The main questions it aims to answer are: * How do different amounts of CSO in the diet affect fasting cholesterol profiles and markers of liver function? * How do different amounts of CSO in the diet affect fasting and post-meal markers of lipid metabolism (i.e. triglycerides) and glycemic control (i.e. blood sugar and insulin)? * How do different amounts of CSO in the diet affect fasting and post-meal markers of chronic disease risk factors such as oxidative stress, inflammation, coagulation potential, and appetite control? Participants will be asked to: * Consume provided breakfast shakes and snacks daily for 28-days. * Attend three weekly short visits for fasting blood draws, body measurements, and collect the next week of study materials. * Attend two longer (5.5 h) testing visits which include eating a standardized breakfast meal and having blood drawn periodically before and after breakfast. Researchers will compare CSO LOW, CSO MID, CSO HIGH, and Control groups (receiving a mixture of oils) to see if lower doses of CSO in the diet impart the same health benefits as previously shown with high doses of CSO.

Dose Response Effects of Pecan Consumption

The bioactive compounds contained in tree nuts have been shown to beneficially affect cardiometabolic health outcomes. Pecans contain more total phenols, sterols, and flavonoids than any other tree nut. They also are a rich source of polyunsaturated fatty acids (PUFAs), fiber, vitamin A, vitamin E, folic acid, calcium, magnesium, phosphorus, potassium, and zinc. These bioactive components in pecans are likely the reason for the previously documented improvements in cardiometabolic health. The specific aims of this study are to: * Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on fasting and postprandial blood lipids. * Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on plasma markers associated with overall health. * Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on subjective and physiologic postprandial measures of hunger and satiety. Participants will be asked to: * Consume pecans daily for 28 days or maintain their current habitual diet. * Attend three short weekly visits for fasting blood craws, body measurements, and collect their next week's supply of study materials. * Attend two longer (5 h) testing visits which include consuming a standard breakfast meal and having their blood drawn periodically before and after breakfast. Researchers will compare pecan LOW, pecan MID, pecan HIGH, and the Control group to examine the physiologic effects of incorporating various dosages of pecans into one's diet.

A Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of HRS9531 Injection in Adolescents With Obesity

The aim of this trial is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of HRS9531 injection compared with placebo in adolescents with obesity

Childhood Obesity - Prevention of Diabetes Through Changed Eating Patterns

The main purpose of the present study is to perform a 10 weeks dietary intervention study with a follow-up for 52 weeks in children from 7-14 years of age with overweight or obesity. In a caloric restricted and increased physical activity setting the control group will consume a low-moderate protein (15E%/day) diet whereas the intervention group will consume a higher protein (25E%/day) diet. Secondary, the investigators want to investigate the effect of frequent follow-up after the intervention, and the overall effect of the lifestyle camp. Compared to the low-moderate protein diet, the investigators hypothesis that a diet with higher consumption of protein-containing foods will more effectively induce weight loss (a reduction in BMI-SDS) or weight maintenance in children with overweight or obesity, and improve quality of life, and risk factors for type 2 diabetes.

Lille Study for Childhood Health Promotion

Obesity could be avoided but once declared it become a chronic disease with numerous health complications, including cardiovascular and metabolic diseases, cancers, and finally a loss of life expectancy. Considering that after the age of 6 years old, half of the obese children will become obese adults, the WHO has been declared childhood obesity prevention as a health priority area. Large-scale prevention of obesity is challenging and it would be more efficient to proceed to early identification of high risks children to implement personalized prevention. The ELIPSE study main objective is to evaluate the efficacy of personalized multidisciplinary care to reduce the BMI of overweight or obese children. A 2 years educational program will be evaluated at short and longer terms (after a 12 months follow-up), and its benefits will also be assessed based on comparison with a historical control group. Along with efficacy evaluation, scientific objectives were designed to investigate clinical, genetic, social, and behavioural risk factors and to analyse potential correlations between these factors and a predisposition to overweight or obesity. Moreover, advanced analyses will be performed to decipher the impact of diverse risk profiles on the efficacy of the educational program. The motive of the ELIPSE study is to promote the health and well-being of children and their families to tackle the health burden represented by childhood overweight and obesity. Combined with innovative scientific objectives, this study ambitions to develop more efficient and more personalized preventive care methods.

Dietary Oils to Sustain Energy Study

The research study is an intervention and feasibility crossover design pilot study designed to assess if consuming 3 study foods made with either soybean oil or palm oil per day for 4 weeks can alter whole blood, plasma and erythrocyte fatty acids and body weight in overweight/obese adults. Additionally, the study will assess the adherence to consuming 3 study foods per day for 4 weeks and to assess if participant remain unaware of (or masked to) which study food group (soybean oil vs palm oil) they are consuming.

Solutions for Hunger And Regulating Eating

The objective of this proposed study is to collect efficacy data on ROC+ compared to an active comparator (AC) and to Behavioral Weight Loss (BWL) for participants who are high in Food Responsiveness.

Timing Exercise Training as Strategy to Improve Insulin Sensitivity and Substrate Metabolism in Men and Woman With Pre-diabetes

n a retrospective analysis of an exercise training program performed either in the morning or afternoon, we found that the afternoon training group improved their peripheral insulin sensitivity and fasting plasma glucose levels to a greater extent than the morning group. However, underlying mechanisms are unclear. The primary study endpoint is nocturnal glucose levels measured by a continuous glucose monitor (CGM).

Healthy Lifestyle Before and During Pregnancy to Prevent Childhood Obesity - the PRE-STORK-trial

Introduction: The prevalence of childhood overweight and obesity has risen from just 4% in 1975 to more than 18% in 2016. Little is known about adiposity of the infant, but it positively associates to the mother's BMI. Globally, the prevalence of overweight has tripled since 1975 and is now affecting one of three Danish women at the time of pregnancy. However, despite increasing awareness of obesity and accumulating evidence of its health consequences limited effect of intervention in childhood obesity exists. Maternal obesity before conception, an excessive increase in body weight during pregnancy and physical inactivity are some of the risk factors suspected of infant adiposity. Lifestyle interventions during pregnancy have shown limited or no effect in the offspring. Therefore, renewed effort to improve the prevention of childhood obesity is warranted. Methods and analysis: This is a randomized, parallel group, tailored, multifactorial lifestyle intervention trial in women (age 18 to 38 years) with overweight or obesity (BMI 27 to 42 kg/m2) seeking pregnancy. The women are randomized 1:1 to either the lifestyle or standard of care group. The lifestyle intervention is initiated prior to pregnancy. The lifestyle intervention is set off with a low-calorie diet for 8 weeks and throughout the intervention period (prior to and during pregnancy) participants follow an intervention containing exercise according to the World Health Organization guidelines, healthy diet and mentorship to maintain healthy weight before and during pregnancy.The primary outcome is the difference in neonatal adiposity measured at birth. Finally, a child and family cohort will be established to follow the children throughout childhood for healthy weight development. The study will provide evidence of effects from pre-conception-initiated intervention and have the potential to improve health and quality of life for children. Ethics and dissemination: The trial has been approved by the ethical committee of the Capital Region of Denmark (H-22011403) The trial will be conducted in agreement with the Declaration of Helsinki and monitored to follow the guidelines for good clinical practice. Results will be submitted for publication in international peer-reviewed scientific journals.
