Main research areas


Bettina Ewers has worked with clinical and epidemiological nutrition research and development in relation to chronic diseases for several years with particular focus on the effect on nutritional interventions in relation to patients with kidney disease and diabetes. During the last 15 years she has been responsible for several dietary projects including two large cross-sectional studies and two randomized controlled trials, one study with a cross-over design and one study with a parallel group study design as well as several clinical quality assurance projects with special focus on evaluating the impact of dietitian-led interventions. In addition, she has been responsible for two studies where new tools for assessment of dietary intake and dietary skills in patients with type 1- and type 2- diabetes have been developed and validated including a web-based diabetes-specific food frequency questionnaire and two web-based photographic questionnaires for assessment of patients’ skills in identifying high-carbohydrate foods in the diet and accurate carbohydrate portion size estimation, which are important learning objectives in basic carbohydrate counting. Her special areas of interest are research and development generating better evidence for the effect of dietary treatment by dietitians on self-management, health-related behavior and clinical important outcomes in patients with diabetes supporting new approaches for nutritional education and management, which is easy to translate into practice and incorporate into the daily life by patients as well as new methods for evaluating lifestyle intervention programs.


Current research

  • Dietary habits and adherence to dietary recommendations in patients with type 1 and type 2 diabetes as compared to the general population in Denmark based on dietary data from a cross-sectional study including patients with diabetes and the Danish National Survey of Dietary Habits and Physical Activity (2011-13).
  • The BCC Studies - Effects of basic carbohydrate counting (BCC) versus standard outpatient nutritional education: Two randomized controlled trials focusing on HbA1c in patients with type 1 and type 2 diabetes.
  • Dietary food preferences, coronary morbidity and total mortality in the general population: Longitudinal observational results from the Copenhagen General Population Study.
