Longitudinal Interaction Between APOA5 -1131T>C and Overweight Accelerates Arterial Stiffness
Overweight and ObesityThe aim of this study is to evaluate whether the longitudinal interaction between APOA5 -1131C variants and overweight could accelerate age-related increases in arterial stiffness and circulating triglycerides in healthy subjects.
Im(Proving) the CSA Model
Overweight and ObesityNutrition Poor1 moreIn 1986, The Pioneer Valley in Western Massachusetts was home to one of the first two community supported agriculture (CSA) businesses in the USA. In 2014, there were 6,200 CSAs across the states, and today, in the Pioneer Valley alone, there are sixty CSAs. As with many parts of the United States, there are too many CSAs competing for the same pool of middle and upper-class customers. In his research at the University of Massachusetts in 2014, Mark Paul stated CSA farms are trapped in a lose-lose conundrum in which the farmers are not making enough money for a living wage, while simultaneously CSA shares are too expensive for many community members. The central challenge facing the CSA model moving forward is to provide fair compensation to farmers and farm workers, while making shares available at prices that can attract more members of the community. "(Im)Proving the CSA Model" proposes to increase consumption of and access to local products AND to develop new market opportunities for farms by opening the CSA membership base nationwide to low-income consumers and more price conscious middle class consumers. The investigators will do this by researching and documenting the health benefits of belonging to a CSA program. The investigators expect the resulting data to justify insurance-provided cash "wellness" benefits for CSA participation, much like those currently provided for gym membership. A wellness benefit will provide the financial incentive necessary to open CSA programs to lower- and middle-income consumers. The two-year research study intends to demonstrate that enrolling community health center patients in a Community Supported Agriculture (CSA) program is feasible and leads to dietary improvements that would be expected to offer clinical benefits in larger scale studies over longer timeframes. To maximize the knowledge gained from participation in this study, the investigators will measure several self-reported, laboratory, and clinical outcomes, but the primary purpose of this study is to provide pilot data for the model. To test this the investigators will implement a randomized controlled clinical trial design, with individual-level randomization of 120 participants, assigned in 1:1 ratio to receipt of a CSA membership (goal: 60 participants) or enhanced usual care (goal: 60 participants).
Specificities of the Eccentric Exercise: Energy Expenditure and Nature of Oxidized Substrates
OverweightHealthy1 moreMain objective of this clinical trial is to compare the oxidation rates of main carbohydrate and lipid substrates during exercises carried out in eccentric dynamic pedaling mode on a cycloergometer compared to concentric exercises (classic pedaling) at the same oxygen consumption (VO2). The hypothesis is that lipid oxidation during an eccentric exercise is higher than lipid oxidation during a concentric exercise, done in humans at the capacity of 30% of VO2max.
Hypertension in High School Students
Hypertension in AdolescenceAdolescent OverweightHypertension and obesity in the young population are major risk factors for renal and cardiovascular events, which could arise in adulthood. A candidate-gene approach will be applied in a cohort observational study, in which investigators will collect data from high school adolescent students. Participants underwent anthropometric and blood pressure measurements, as well as saliva and urine sample collection for genomic DNA extraction and renal function evaluation, respectively. Candidate genes previously implicated in salt-sensitive hypertension in adults will be tested to verify impact on blood pressure (BP) also among adolescents. Since inflammatory mechanisms may be involved in pathophysiology of hypertension and in endothelial dysfunction and atherosclerosis through reactive oxygen species, the baseline urinary excretion of inflammatory and oxidative stress markers in a subgroup of adolescents stratified according to ADD1 (alpha adducin) rs4961 genotypes will be assessed.
BMI Development and Risk of Overweight and Obesity in Children
Health BehaviorChild Obesity1 moreThe goal of this observational study is to investigate differences in attained BMI and the proportion of overweight/obesity at school entrance in children who attended kindergartens actively delivering a community-based health promotion and obesity prevention intervention compared to children who attended usual care kindergartens. Further questions it aims to answer are: Explore the prevalence of attainted overweight/obesity in children at six years of age, who attended kindergartens delivering intervention compared with usual care kindergartens. Explore the development of obesity, overweight and normal weight in children from three-, four- to six years of age, who attended kindergartens delivering intervention.

The Effects of Puberty and Weight on Sugar Metabolism in Children
OverweightLeanness1 moreOur goal is to investigate how hormones that control blood sugar, hunger, and stomach emptying change with puberty and being overweight. These substances change with a meal. For this, we need to compare lean and overweight children. We need to study them before and during puberty. All children in the study will be tested before and after a liquid meal.
Diet and Well-being of Young Danish Children Born by Obese Mothers
GrowthOverweight2 moreThe overall aim is to provide a detailed description of growth, development and risk factors for later disease, especially obesity and metabolic disease in infants born by obese mothers and to compare them with a group of infants born by mothers without any restriction in prepregnancy BMI (SKOT I).
Explorative Assessment of Biomarkers in Overweight and Obese Subjects
PrediabetesThe rationale for this trial is to apply a simple and minimally strenuous pre-screening approach prior to performing more extensive trial-specific screening and baseline-characterization activities in the resulting pre-selected population of subjects.
Validation of Hand Held Indirect Calorimeter in Overweight and Obese Patients
ObesityThe purpose of this study is to determine, in a group of overweight or obese volunteers, if a handheld indirect calorimeter can accurately measures oxygen consumption to determine resting metabolic rate compared to a portable indirect calorimeter.
