NCT03369496
Social networks, social capital, i.e., network-accessed resources, and neighbourhood environments have been shown associated with a range of health behaviours and conditions, including obesity, physical activity, nutrition, and mental health. Research on social capital and health in Montreal has shown the importance of network social capital for a person's subjective health status, sense of control, self-reported physical activity, and obesity. Research has also shown high social capital to reduce health service use, mental health service use, and improve the management of chronic illnesses. Despite advances in the understanding of social capital and its link to health and health service use, most research on social capital is cross sectional and is unable to identify the causal pathways linking social networks and capital to health and health care use. Longitudinal research would strengthen the evidence base for designing interventions to prevent or delay the use of health services, particularly in older adults. This research has three main objectives: (1) transform the original sample of Montreal Neighbourhood Networks and Healthy Aging (MoNNET-HA) households (n=2707) into a panel study, (2) link the MoNNET-HA participant data to their Quebec Health Insurance Registry (Régie de l'assurance maladie (RAMQ)) information, and (3) assess the feasibility of extending the MoNNET-HA panel by one wave to include participant's core network members. Unique about the original MoNNET-HA sample is that it purposefully oversampled older adults (\> 64 years old) but remains representative of Montreal adults at various ages and income levels. In addition, MoNNET-HA data is integrated into a GIS database which allows researchers to examine the effects of neighbourhood environmental characteristics on health. By linking MoNNET-HA data to RAMQ, researchers will be able to examine patterns of diagnosed health conditions, (e.g., fractures, depression), pharmaceutical use and adherence, and formal health care use over time. Transforming the cross-sectional study into a panel study would also allow researchers to examine longitudinally the dynamics of health and health care utilization among Panel participants over the life course, and the causal pathways linking neighbourhoods and networks to health and health care use.
NCT02810041
Overweight and obesity are public health problems worldwide. Even though heredity may be one of the causes the diseases, the vast majority of cases is rather linked to a sedentary lifestyle associated or not with a low-variety, high-calorie diet. Many diets and slimming methods propose low-calorie meals or physical exercise, and the consequences of these are sometimes negative with advancing age (muscle wasting). Certain studies have shown the efficacy of foods with antioxidant properties on the reduction of blood pressure, Low Density Lipoprotein (LDL)-cholesterol and weight or on the distribution of fat mass-lean mass. The investigators put forward the hypothesis that the daily consumption of two yoghurts containing XXS, a mixture of natural polyphenolic compounds -rich in quercetin- from plant extracts, could lead to weight loss, a better fat mass-lean mass distribution and an improvement in markers of oxidative stress in overweight persons aged 50 to 65 years.
NCT03650790
The complement C1q tumor necrosis factor-associated protein-9 (CTRP-9), which is responsible for regulating cardiovascular and metabolic functions, increases vascular relaxation by pathway dependent on AMPK / endothelial nitric oxide synthesis (eNOS). The aim of this study was to investigate CTRP-9 levels in pregnant women with preeclampsia.
NCT03097237
The overall aim of this study is to investigate whether a diet rich in rye fiber from wholegrain rye, compared to refined wheat, as part of a hypocaloric diet leads to larger weight loss and lower body fat content after 12 weeks of intervention. Furthermore the study will investigate the effect on appetite as a potential underlying mechanism for differences in weight loss and body fat reduction.
NCT03657927
Along with the technological advances in medicine, videolaryngoscope is the most commonly preferred technique for intubation of expected difficult airway management such as morbidly obese patients. In this prospective controlled clinical study, the purpose is to compare C-MAC videolaryngoscope and McGrath MAC videolaryngoscope in respect to duration of intubation, haemodynamic response, and complications related intubation of morbidly obese patients undergoing bariatric surgery.
NCT03721536
Low-flow anesthesia has been used for years with positive results, but its effects on hemodynamic parameters and oxygenation are not clearly known in high-risk morbidly obese patients who are prone to pulmonary dysfunction related to the obesity. Therefore, this prospective randomized study aimed to compare the effects of low-flow (0.75 L/min) and normal-flow (1.5 L/min) anesthesia on hemodynamic parameters and oxygenation in morbidly obese patients undergoing laparoscopic bariatric surgery.
NCT02746939
The study is designed to examine whether curriculum, designed in partnership with teachers at Moreland Elementary school in West St. Paul and Mayo Clinic InSciEd Out scientists, is able to influence the behavior and health literacy of students. This information will be collected in surveys before and after the students are given the curriculum during the school day.
NCT02148692
Postoperative respiratory failure, particularly after surgery under general anesthesia, adds to the morbidity and mortality of surgical patients. Anesthesiologists inconsistently use positive end-expiratory pressure (PEEP) and recruitment maneuvers in the hope that this may improve oxygenation and protect against postoperative pulmonary complications (PPCs), especially in obese patients. While anesthesiologists tend to use PEEP higher than in non-obese patients. While it is uncertain whether a strategy that uses higher levels of PEEP with recruitment maneuvers truly prevents PPCs in these patients, use of higher levels of PEEP with recruitment maneuvers could compromise intra-operative hemodynamics. The investigators aim to compare a ventilation strategy using higher levels of PEEP with recruitment maneuvers with one using lower levels of PEEP without recruitment maneuvers in obese patients at an intermediate-to-high risk for PPCs. We hypothesize that an intra-operative ventilation strategy using higher levels of PEEP and recruitment maneuvers, as compared to ventilation with lower levels of PEEP without recruitment maneuvers, prevents PPCs in obese patients at an intermediate-to-high risk for PPC.
NCT01231074
Recent but limited short term studies have shown that Metformin can slow down weight gain in obese children and in children with psychotropic-induced weight gain, two distinct pediatric populations that are at risk for obesity related co-morbid conditions. The purpose of this study is to conduct a long term prospective pilot cohort study to investigate the use of Metformin to prevent or decrease weight gain in two cohorts of children: 1) children with psychotropic induced weight gain on Metformin and 2) children with BMI above the 95th percentile on Metformin. Both study populations will be enrolled in a lifestyle weight management program
NCT03215641
This study evaluates the role of personal activity trackers to help improve weight loss or weight maintenance for children and their parents enrolled in a comprehensive weight loss program.
NCT01907399
There is a link between activation of the immune response inducing chronic inflammation and both obesity and type 2 diabetes. To date, however, the cause(s) of this inflammation, the mechanisms of the inflammatory cascade and the type of cells involved are not completely known. The aim of our project is to study the principal cell types involved in the immune response from a quantitative and functional point of view in obese diabetic patients versus obese non-diabetic patients and healthy subjects who are neither diabetic nor obese. Despite possible inter-individual heterogeneity of immune cells, the fact that this work will be carried out by an accredited team with considerable expertise in the study of almost all the different types of immune cells will probably make it possible to know whether cell dysfunction and inflammation are associated with obesity or rather linked to insulin resistance. This study will be completed later by a second study on cell infiltration in adipose tissues in the 3 groups defined above. Better understanding of the physiopathology and especially the mechanisms and type of cells involved in obesity-related inflammation could quickly lead to the development of appropriate therapies that could act specifically on the cells involved and thus preclude the onset of complications.
NCT02571387
The purpose of this study is to evaluate the efficacy of a daily 12-month computerized mindfulness-based intervention in obese patients diagnosed with Binge Eating Disorder (BED) on: impulsive eating, motivation toward exercise, and weight loss.
NCT03009825
The purpose of this study is to investigate the associations between lifetime exposure to traumatic events, emotion regulation strategies, and eating pathology of patients with obesity.
NCT02861703
Obesity presents serious psychological and physical consequences for breast cancer survivors, including diminished quality of life, poorer prognosis and increased mortality. As such, there is a great need to develop strategies for these women to maintain optimal body weight. Diet and exercise have been shown to lead to successful weight loss among this population but these effects are seldom sustained, plausibly because these efforts alone overlook less obvious, but equally important, psychosocial factors that can interfere with prolonged progress. This study will implement a group-based intervention addressing diet and exercise along with other psychosocial issues related to survivorship such as depression, fatigue, body image and social support. Based on the growing popularity and benefits of computer-based health care, including convenience and anonymity, this intervention will also be offered online, representing the first of its kind. It is hypothesized that the intervention will be feasible to implement and acceptable to its participants. It is also hypothesized that the intervention will yield meaningful and sustained changes in body weight, body mass index, waist circumference (primary outcomes), as well as mental well-being, quality of life, and body image (secondary outcomes). This research has the ability to improve the long-term health of breast cancer survivors by incorporating psychosocial interventions into standard medical care practices and has the potential to increase accessibility of these services using online technology.
NCT02626819
Compared to the general public, a higher percentage of Veterans are obese or overweight with a weight-related medical condition. The VA currently offers an effective weight management program called MOVE!, but the majority of eligible patients do not attend. Veterans see their primary care providers (PCPs) very frequently, making it an important place to receive information on weight management. However, PCPs often fail to discuss weight management with patients, so interventions are needed to encourage weight management counseling within the team-based care model used in primary care at the VA. Investigators used focus groups, interviews, and other research methods to develop the MOVE! Toward Your Goals (MTG) intervention. This intervention combines online tools, counseling by a health coach, and the team-based care model to deliver weight management information to patients. Investigators will conduct a randomized controlled trial of 320 Veteran patients and their providers at two VA sites (Manhattan and Brooklyn campuses, New York Harbor Healthcare System) to study the impact of the 12-month MTG intervention when compared to Enhanced Usual Care. Veterans in the MTG intervention arm will take the MTG tool, receive personalized weight management materials, health coach counseling, and go to their scheduled primary care (PC) visit. After the initial visit, MTG-arm Veterans will receive follow up telephone coaching over 12 months. All Veterans will attend follow-up visits at 3, 6 and 12 months to assess body mass index, diet and physical activity, and goal attainment. The objectives of this study are to: (a) test the impact of the MTG intervention on weight and behavior changes; (b) identify predictors of weight loss in Veterans who use goal setting techniques; and (c) determine the impact of the MTG intervention on primary care team obesity-related counseling practices and attitudes.
NCT03283644
This study investigates the chronic long-term health condition of obesity and its effect on neutrophil function and the inflammatory response
NCT01237041
Background: \- Overweight and obese children and adults often have lower levels of growth hormone in the blood. Regulation of growth hormone may be tied to weight and free fatty acids in the blood. Current tests of growth hormone (such as those used when evaluating the heights of children who are markedly shorter than other children of comparable age) may be affected by other factors, including obesity. Researchers are interested in evaluating the levels of growth hormone and free fatty acids in the blood of children between 7 and 14 years of age who weigh more than children of a comparable age, or who are shorter than other children of a comparable age and have been recommended for growth hormone testing as part of an evaluation for their height. Objectives: \- To determine the effect of changes in free fatty acids in the blood on changes in growth hormone secretion in overweight or shorter children and young adolescents. Eligibility: \- Children and adolescents between 7 and 14 years of age who weigh more than or are shorter than other children of a comparable age and do not have any medical illnesses. Design: * Participants will have two study visits, one of which will be a half day screening visit in the outpatient clinic and one of which will require 2 nights as an inpatient at the National Institutes of Health Clinical Center. * Participants should not eat or drink anything except water after 10 PM the night before or on the morning of the screening visit. * At the screening visit, participants will have a physical examination and medical history, provide blood and urine samples, have an oral glucose tolerance test (to check blood sugar levels), and have an x-ray of the left hand to check bone age. * The inpatient study visit will involve a physical examination and medical history, a full x-ray scan to study body fat and muscle, frequent blood tests throughout the visit, and various medications to stimulate growth hormone production and lower levels of free fatty acids in the blood.
NCT02160847
The purpose of this study is to help overweight or obese children to maintain or reduce their body mass index (BMI) through the home-based parent training program the investigators developed called DRIVE. The investigators hypothesize that children from families that receive the DRIVE program will show greater maintenance or improvement in their BMIs than families who do not receive DRIVE.
