Filter by:The primary aim of this study is to reduce household food waste and improve individual nutrition. This will be achieved using the FoodImageTM smartphone app 1, a novel method for measuring household food acquisition, food intake, and food waste decisions, to assess the efficacy of a smart intervention that targets food waste reduction and diet quality improvement. The intervention is designed to improve nutrition by offsetting intake of less nutritious foods with increased fresh fruit and vegetable (FV) intake while simultaneously reducing household food waste via strategies tailored to participating households.
With this study, researchers want to conduct ambulatory studies in which people (healthy, with T2D, or at-risk of T2D) will consume a variety of pre-set and conventional meals in free-living conditions while wearing one or more continuous glucose monitors (CGMs) and, to assess physical activity, a smart watch. With data from these devices, researchers will develop algorithms that can predict the content of a meal.
The prevalence of obesity is one of the main public health problems worldwide, reaching 18% among young people between 5 and 19 years of age in 2016. One possibility of effective treatment can be the Mediterranean diet (MD). Therefore, it is proposed to carry out a nutritional intervention based on this diet to more effectively reduce obesity in adolescents. The main purpose of this multicentre study is to assess whether an energy-restricted Mediterranean-style diet (MD) intervention including healthy products from the Mediterranean basin (mixed nuts, pomegranate and hummus) and sourdough bread is more effective against obesity and associated CVD risk factors than a conventional low-fat diet carrying out a multicentre nutritional and clinical intervention study specifically targeting obese/overweight adolescents (13-17y) from different Mediterranean countries; all combined with an educational web-application designed to encourage healthy behaviours. It is a multicenter, randomized, controlled intervention study conducted with adolescents with obesity/overweight ≥90 percentile who do not suffer from any chronic disease. 240 subjects will be recruited from three Mediterranean countries: Italy (Parma), Portugal (Coimbra) and Spain (Reus), specifically 80 participants per country, 40 adolescents as an intervention group and 40 as a control group, in Reus. The intervention study is scheduled to begin in January 2021. The intervention group will receive a diet based on the characteristics of MD, and will be reinforced with satisfying and healthy Mediterranean foods such as sourdough bread (2 servings of 50-60g / day), squeezed pomegranate (4 servings of 200ml / week), hummus/chickpeas (2 portions of chickpeas of 150-200g / week, one in hummus format) and mixed nuts (4 servings of 30g / week); and the control group will receive a recommended diet based on the consumption of low-fat foods. A caloric restriction of 20% of the total energy requirements will be applied to both groups in adolescents with BMI ≥95 percentile (obesity) and a caloric restriction <20% of the total energy requirements will be applied in adolescents with BMI ≥90 to <95th percentile according to overweight (gender/age / physical activity). The diet will be applied for 4 months in both groups. Adolescents from both groups will be given a motivational interview and will be provided with an educational website that will be used during the intervention, through which they will learn.
The purpose of this project is to study the molecular and metabolic profiles in human plasma, urine and microbiome composition following the consumption of broccoli sprouts.
Health behaviour applications (also referred to as "apps") have the potential to provide several advantages for motivating behaviour change for health and well-being. Finding ways to increase and sustain health promoting behaviour changes has been a challenge during health app development. Gamification, which is the use of game elements in a non-game situation, shows promise and has proven effective in many fields. However, key questions remain concerning how to use gamification in apps to modify health behaviour, especially to support adherence to dietary pattern recommendations. To investigate and summarize the current evidence, a systematic review of the totality of evidence from clinical trials and observational studies will be conducted to capture and distinguish the types of gamification strategies that may be most effective in improving and sustaining health promoting behaviours to inform future health behaviour app development.
It is a prospective randomized trial on 218 subjects, 109 for each arms. The purpose of this trial is to compare very low calorie diet and metabolic surgery induced weight loss and its maintenance.
The CHEER study takes advantage of a natural experiment happening in South Carolina (SC). The South Carolina Department of Social Services implemented new healthy eating and physical activity standards through a state-wide policy for family child care homes that participate in the ABC Grow Healthy program. Thus, CHEER is a quasi-experimental, two-group, pre-test/post-test design study.
This study will compare a new weight loss program that focuses on a healthy eating pattern, with WW™ (formally Weight Watchers), an effective and widely available weight loss program. Study researchers have developed an adapted version of the Mediterranean eating pattern to be more acceptable and realistic for southerners; this adapted version is known as "Med-South." Those who take part in the study will be randomly assigned to either the Med-South weight loss program or WW™. Both programs will last for 2 years with measurement visits at the start of the study and at 4-, 12- and 24-month follow-up. While the primary outcome measured by the trial will be weight loss at 24 months, researchers will collect other data which may show additional health benefits of the Med-South diet. The study team will measure blood markers of inflammation, which are known to improve with better diet quality. Researchers will also measure participants' skin carotenoid levels, which increase with greater fruit and vegetable consumption. The study will be conducted within 2 regional catchment areas (n=360 participants) representing a diverse spectrum of patients and settings. Patients with a BMI ≥ 30 kg/m^2 will be enrolled and randomized to intervention or augmented usual care. To assure adequate subgroup representation, ≥ 40% of the sample will have diabetes, ≥ 40% will be male, and ≥ 40% will be African American. The intervention will be delivered in 3 phases over 24 months by research staff: Phase I (4 months) focuses on adopting a Med-style dietary pattern; Phase II (8 months) on weight loss; and Phase III (12 months) on weight loss maintenance. Outcomes will be assessed at 4, 12, and 24 months. The primary outcome is weight loss at 24 months. Secondary outcomes include change in physiologic, behavioral, and psychosocial measures. Researchers will also assess implementation cost and the incremental cost-effectiveness of the intervention relative to the augmented usual care group.
The prevalence of adolescent behaviors that can lead to obesity are alarming, and reduced life expectancy is the future of America's youth if behavioral changes are not implemented to improve health and reduce the obesity burden. Researchers have argued that health literacy is a precursor to health knowledge and is necessary for translating knowledge about healthy choices into behavior, with low health literacy being associated with reduced preventive health behaviors in adults. Given the lack of health literacy-specific interventions addressing adolescents' obesogenic behaviors, the purpose of this study is to examine the preliminary effectiveness of adding a health literacy module to an obesity prevention intervention that addresses adolescents' obesogenic behaviors.
