Filter by:Folate and vitamin B12 deficiencies are associated with various health issues, including anemia, cardiovascular disease, depression, and birth defects. Accurate and objective estimates of dietary intake are necessary to assess any effects of nutritional status in epidemiologic studies. This study aims to develop and validate a three-month semi-quantitative food frequency questionnaire for the assessment of dietary intake of folic acid and vitamin B12, against four*two multiple-pass 24-hr dietary recall among teenage girls in South Ethiopia
It is estimated that 2.3 million Taiwanese have diabetes and there is a 44% increased rate among young adults and adolescents. Poor dietary habits and sedentary lifestyle are the major risk factors for type 2 diabetes. The growing availability of smartphones has boosted the development of new technologies that incorporate the use of digital food photography as health promotion and individualized nutrition care. Digital health technology is also used to prevent and treat diabetes with good degree of successes in the short term but the long term effect remains unknown. The broad aim of this study is to evaluate the effectiveness of digital technology eHealth care for diabetic patients. A total of 300 diabetic patients will be recruited from Diabetes Shared Care Network and community care center in Taiwan and follow up 12 months. A simple randomization by computer system will be used to randomly allocate subjects into 2 groups: control group and eHealth care. The control group (n=100) of diabetic patients will receive conventional health and nutrition education from state registered dietitian. The eHealth care group (n=200) of diabetic patients will receive a 10 mins of food portion size nutrition education using " 3D/AR MetaFood platform" and is required to record their consume meal by food image once a week using Taiwan FoodAPP. Patients in the eHealth group will receive instant feedback from the nutritionists or artificial intelligence (AI) for the information of glycemic index (GI) and glycemic load (GL), and educational video related to healthy eating or how to select GI/GL food. Anthropometry, and baseline questionnaires will be collected at baseline. Blood biochemistry (e.g. HbA1c) and body weight will be collected at baseline, 3, 6, 9, and 12 months. The collected food image data will be used for AI training to identify the relationship between the patient's diet and blood glucose changes over time.
The burden of non-communicable diseases (NCDs) in Rwanda is adding to the health burden in the country which is facing the nutritional transition and the double burden of malnutrition. Diet is an established risk factor in NCDs, hence the importance to assess accurately the changes in dietary habits occurring in the population. The objective is to develop and validate a food frequency questionnaire in Rwanda.
The primary aim of this small study is to test the validity of the Remote Food Photography Method and an updated SmartIntake app in a sample of adolescents. The investigators will test the validity (accuracy) of the method/app at estimating energy intake in free-living conditions over approximately three days compared to doubly labeled water. This is a small study that has low statistical power, but will provide important data nonetheless and inform future research.
The study will assess the accuracy of food capture methods using a novel mobile application. This will be done by comparing the energy and nutrient content of reported foods against those of foods actually consumed (i.e., reported vs actual). Two methods of using the application will be tested: 1. During each eating occasion to report foods and amounts consumed 2. By taking photographs of every food consumed, using the camera functionality of the mobile application and using the application the following day (according to the availability of the study subjects) to report foods and amounts consumed. This is to be consistent with the concept of a 24-hour dietary recall. One group will use a standard 24-hour dietary recall method.
The purpose of this study is to evaluate the influence of dietary restraint, social desirability, and food type on the accuracy of dietary intake reported during a 24-hour recall.
