Filter by:Assessment of dietary intake in large, free-living populations is inherently challenging due to the complex nature of human diet. Advancements in traditional methods of dietary assessment (i.e., web-based dietary recalls or records) have aimed at improving data accuracy while reducing participant burden. Further utilizing food recognition technologies to capture real-time food intake may aid in overcoming limitations of existing methods. Keenoa, an artificial intelligence-enhanced, image-assisted tool, is a newly designed mobile application that may facilitate collection of dietary data. Primarily, the investigators will assess acceptability and usability of Keenoa compared with the traditional, web-based Automatic Self-Administered 24-Hour (ASA24) Dietary Assessment Tool in the Framingham Heart Study Third Generation-based cohorts at examination 4. The investigators will also determine the proportion of participants who complete all three days of dietary assessment, either through Keenoa or ASA24. Further, the investigators will relate dietary determinants of glycemic variability (e.g., percent carbohydrate, fiber intake, etc.), obtained from each dietary assessment tool, to the continuous glucose monitor (CGM)-derived outcomes. With a randomized block design, this study will take place as part of the Framingham Heart Study (FHS) glucose study (R01 DK129305). Currently participants from the Third Generation-based cohorts are asked at their fourth examination to wear Dexcom G6 Pro continuous glucose monitor on either their arm or abdomen for a duration of at least 4 days. During this time, participants are asked to complete 3 consecutive days of dietary record through ASA24. For this trial, the investigators will randomize the dietary assessment tool weekly between ASA24 and Keenoa, therefore, depending on the week of administration, participants will be randomized to either a 3 days dietary record via ASA24 or a 3-day dietary record through Keenoa. This trial will last a total of 6 weeks.
This is a randomized controlled trial, aiming to investigate whether a time-restricted eating (TRE) can reduce the incidence of gestational diabetes mellitus (GDM) in high-risk pregnant women. Investigators intend to conduct a 3-month randomized controlled study to compare the effects of 10-hour TRE and habitual eating time on GDM under the same energy intake.
A cross-sectional study representative of the Polish population of children aged 5 months to 6 years conducted in the cross-sectional study model, the main objective of which is to assess the nutritional value of the diet of children aged from 5 months to 6 years with regard to the basic macronutrients: protein (P), fat (F), carbohydrates (C). The study will include: dietary interviews, which will include the Food Frequency Questionnaire questionnaire (FFQ) and a 3-day food diary, as well as anthropometric measurements. The study will involve 1,000 children who will be selected by a random draw based on government database. The survey will be conducted by trained field interviewers - training will be provided by a dietician and an anthropologist. The study also included validation of the FFQ questionnaire.
The goal of this trial is to assess the effect on the quality of life (QoL) of recommending a fat-free diet versus a balanced WHO diet in symptomatic patients with gallstones and in patients undergoing cholecystectomy for gallstone disease. The main question it aims to answer is: • Is balanced WHO diet as good as low-fat diet in terms of patient reported outcomes when gallstone disease is managed non-operatively (RADIGAL-1) or cholecystectomy is performed (RADIGAL-2)? A validated QoL questionnaire (Gastrointestinal Quality of Life Index - GIQLI) will be administered both at baseline and during follow-up. Analysis of covariance with ordinary least squares estimation will be applied to estimate between-group differences in GIQLI scores at 3 months (primary endpoint). Patient adherence and the disease-related symptoms occurrence or hospitalizations will also be appraised (secondary endpoint). Participants presenting with biliary colic or acute cholecystitis (RADIGAL-1) or undergoing cholecystectomy for gallstones (RADIGAL-2) will: - be randomly assigned to recommending either a fat-free or a balanced WHO diet . - be contacted via phone call to complete the GIQLI questionnaire and document overall adherence to the diets and secondary outcome events. This trial examines the impact of diet on adverse events in gallstone disease, representing the first randomized study to focus on this aspect.
With funding from the United States Department of Agriculture (USDA), the Tufts University's Friedman School of Nutrition Science and Policy will be implementing a new, health and wellbeing program for Head Start educators at ABCD Head Start Centers in the greater Boston area. The purpose of this study is to evaluate the combined impact of a health and wellness program and behavior change guides. The evaluation will focus on ABCD Head Start educators as the study population. Tufts University's Friedman School of Nutrition Science and Policy is responsible for implementing and evaluating this new intervention through surveys and analysis of administrative (health and wellness App) data. A paper and pencil survey will be used to gather information on dietary, physical activity, and sleep behaviors. The surveys will also include a module on satisfaction with the health and wellness App and Guides. Survey data will be combined with the administrative data about App utilization.
Lay language summary: Women are younger and menstruating about monthly ("pre-menopausal") often have fluctuations in the food they eat ("dietary intake") across the menstrual cycle. However, relationships between food intake and appetite, metabolism, body composition (i.e., the proportion of muscle and fat), physical activity and premenstrual symptoms have not been reported. This study will measure appetite and food intake in laboratory and usual life settings in healthy pre-menopausal women in two hormonally different parts of the menstrual cycle. Data on ovarian hormones, metabolism, body composition, physical activity and premenstrual symptoms will also be collected to assess their potential relationship with food intake.
The study aims to explore how dietary habits affect oral health in children with autism. By examining a cross-section of the autistic paediatric population, the research seeks to identify patterns or specific dietary preferences that may contribute to or mitigate oral health issues. This observational study does not intervene in participants' diets but observes existing habits and their oral health outcomes, aiming to provide insights that could guide better dietary recommendations and oral health practices for children with autism.
The goal of this clinical trial is to evaluate cardiometabolic and inflammatory parameters in kidney transplant recipients after transitioning to a plant-based diet (PBD). The main aims of the study are as follows: - To test the feasibility of transiting renal allograft recipients who are > 3 months post-transplant to a PBD - To study the effect of a PBD on cardiometabolic parameters in kidney transplant recipients - To assess the effect of a PBD on peripheral blood Th17/Treg ratio and systemic inflammation in kidney transplant recipients Participants will be asked to: - Complete a 2-week investigator-designed PBD transition program - Follow a PBD for a minimum of 16 weeks - Consent for blood draws, urine samples, and fecal samples along with physical exams - Complete intermittent food frequency questionnaires and quality of life questionnaires - Periodically meet with investigators and other study participants Researchers will compare baseline measurements with future measurements for each participant.
The present study is testing spermidine treatment in elderly patients with coronary artery disease. The study is a randomized, double-blind, placebo-controlled, two-armed, parallel-group, single centre, clinical study.
This study will evaluate a newly developed multimodal health intervention including dietary approach to stop hypertension (DASH) diet, exercise (Ex), and medication adherence (MA) using motivational interviewing (MI) counselling (DASH-Ex MAMI) for hypertensive Jordanian adults in primary care settings.
