Filter by:The prevalence of overweight and lifestyle related diseases such as cardiovascular disease (CVD) and type 2 diabetes (T2D) is increasing world wide. The metabolic syndrome (MeS) is a condition characterized by abdominal obesity, high blood lipids, high blood pressure and elevated blood sugar. MeS is associated with an increased risk of developing CVD and T2D. Dietary fibers and whey protein have independently shown beneficial effects on several of these risk factors in previous studies. Whey protein is furthermore seen to show positive effects on bone turnover. The purpose of this trial is to investigate whether an increased intake of dietary fibers and whey protein (separately or combined) over a period of 12 weeks will affect the risk markers of MeS and bone turnover in abdominally obese subjects. A total of 80 people with abdominal obesity will be included. The design is a randomized, double blinded, controlled dietary intervention trial. Subjects are assigned to one of four experimental groups. Each group are provided with test products containing either high or low whey protein and high or low dietary fibers to replace part of their regular diet. The subjects are instructed in how to incorporate the test products in their habitual diets in order to maintain weight stability. The primary outcome is postprandial lipaemia (PPL) - an independent risk factor of developing CVD. PPL is estimated by performing a standardized high fat meal test during which postprandial level of triglycerides is measured. The authors hypothesize that a diet of high content of whey protein and high dietary fiber during 12 weeks will induce a reduction in PPL.
Aging has been associated with reduced bioavailability of nitric oxide (NO) and endothelial dysfunction. Beetroot consumption, a nitrate-rich food, has been associated with increased NO bioconversion, which may promote beneficial effects on vascular health. The present study evaluated the effects of a beetroot-based nutritional gel (BG) on vascular function, arterial stiffness and blood pressure in the elderly at cardiometabolic risk. Twenty elderly individuals were submitted to BG and nitrate-depleted gel (PLA) interventions. Brachial flow-mediated dilation (FMD), blood flow velocity (BFV), peak wave velocity (PWVβ), augmentation index (AI), stiffness parameter (β), pressure-strain elasticity modulus (Ep), arterial compliance (AC), muscle oxygenation and function were measured 90 min after interventions. Urinary nitrate, nitrite, systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were measured at baseline, 90 min and 150 min after interventions.
The purpose of the WorkACTIVE-P study is to assess the outcome of an innovative multi-component intervention focused on increasing energy expenditure and re-balancing the disrupted energy balance equation of sedentary workplaces with an ultimate target of reducing workers' abdominal obesity.
To evaluate the effectiveness of acupuncture therapy combined with healthy education for patients with abdominal obesity.
Abdominal obesity and its metabolic consequences, particularly type 2 diabetes, require personalized nutritional monitoring. Today, it is not always possible to provide patients with appropriate care to both, the diet plan, physical activity, stress and sleep management. Emerging data have shown the effectiveness of remote support (e- coaching), in order to increase the level of physical activity and reducing calorie intake which causes weight loss similar to that obtained during a face to face consultation. Compared to a food survey conducted by a dietician, the dietary survey MXS computer software showed similar results on the collection of nutritional data. Furthermore, users preferred this method of remote collection compared to direct interview. The investigators recently developed a tool for e-coaching combining this computerized dietary survey and education and support modules on diet and physical activity (MXS- health program) for the patients. The aim of the investigators' study is to compare efficacy of this new software vs usual care.
In the Belly Fat study, the effects of two different caloric-restricted diets on metabolic health will be examined in male and female subjects with increased abdominal adiposity (BMI >27 kg/m2). Metabolic health is defined as health of the primary metabolic organs the liver, gut and the adipose tissue, examined in a static state as well as after the application of a challenge test. The diets are equally caloric-restricted, but differ in nutrient composition. It is hypothesized that one of the two diets causes a larger improvement in organ health and reduction in liver fat.
Currently, the incidence of obesity and obesity-related disorders is reaching epidemic proportions, which entails an increasing burden for health care systems. The association of obesity with other risk factors for type 2 diabetes mellitus and cardiovascular disease, such as insulin resistance and hypertension, is often referred to as the metabolic syndrome. During recent years, salt-sensitivity of blood pressure has emerged as an additional cardiovascular risk factor that is related to obesity and other key components of the metabolic syndrome. The underlying pathophysiological mechanisms of these interrelationships are complex and incompletely elucidated. Microvascular dysfunction has been proposed as a link between insulin resistance and hypertension in obese individuals. In addition, impairment of microvascular function was found to be associated with salt-sensitivity of blood pressure. Increased aldosterone levels, as observed in obese individuals, might be a cause of microvascular dysfunction-induced salt-sensitivity and insulin resistance. Aldosterone not only gives rise to sodium-retention in the distal tubule of the kidney, but was also found to impair endothelial function and thus lower NO-availability, which is characteristic of microvascular dysfunction. In addition, elevated aldosterone levels are associated with both hypertension and insulin resistance, which is illustrated in patients with primary aldosteronism, but also in the general population. The investigators hypothesize that increased aldosterone levels in obese individuals lead to impairment of microvascular function through reduction of NO-availability. This microvascular dysfunction is suggested to play a central role in the pathogenesis of salt-sensitive hypertension and insulin resistance.
People who originate from the Indian subcontinent known as South Asians are the fastest growing group of non-white Canadians. They suffer an excess prevalence of abdominal obesity, type 2 diabetes and heart disease. They also develop these risk factors at significantly lower body weight and at younger ages compared to people of European origin. The purpose of SAHARA (South Asian HeArt Risk Assessment) Trial, is to recruit 330 South Asians from Ontario (Principal Investigator: Dr. Sonia Anand) and British Columbia (Co-investigator: Dr. Scott Lear), who use the internet, email and other multimedia devices. Among these participants, the investigators will compare the effectiveness of a 12-month interactive multi-media health behaviour intervention to usual care in reducing cardiac risk factors. This intervention enables participants to set their health goals and provides health messaging and feedback designed to improve their smoking, dietary habits and physical activity. In addition, the investigators will test if knowledge of genetic risk for heart attack influences behaviour change and their heart health risk factor profile. The information generated from SAHARA will enable individuals, physicians, health professionals, and policy makers to develop risk factor modification programs to prevent cardiovascular disease in this high-risk group.
The aim of this study is to develop an intervention that will produce a sustained improvement in physical activity and chronic stress as a means to slow the menopause-related accumulation of visceral adipose tissue in mid-life women.
Obesity is strongly associated with risk of cardiovascular disease (CVD). Data increasingly suggest that visceral adipose tissue (VAT) accumulation -- or increased abdominal fat -- is particularly deleterious to cardiovascular health, but further study is needed to test this idea. Increased abdominal fat may also be associated with lower secretion of a hormone called growth hormone (GH), which helps the body burn fat. The current study aims to carefully characterize relationships between abdominal fat and CVD. In addition, by using a medication called growth hormone releasing hormone, which is a strategy to reduce abdominal fat, the investigators will test the hypothesis that abdominal fat contributes uniquely to increased arterial inflammation. In the first part of this study, the investigators will investigate both lean (healthy weight) individuals and individuals with increased abdominal fat. The investigators will study their body composition, cardiovascular risk measures, insulin sensitivity, and growth hormone dynamics, with the hypothesis that abdominal fat, independent of general obesity, will be strongly associated with arterial wall thickening and atherosclerotic inflammation. The investigators will assess arterial wall thickness, plaque morphology, and atherosclerotic inflammation, and the investigators will determine associations between these variables and regional fat accumulation, with particular attention to abdominal fat. The second, treatment part of the study will be only for individuals with increased abdominal fat who are found to have low growth hormone secretion. In that part of the study, the investigators will test the effects of a growth hormone releasing hormone (GHRH) analogue to reduce abdominal fat and, consequently, reduce arterial inflammation. The investigators hypothesize that abdominal fat reduction, independent of changes in growth hormone, will reduce arterial inflammation and arterial wall thickness.
