Abstract
Research is limited regarding nutritional knowledge and behaviors and glycemic control in adolescents with type 1 diabetes (T1D) and comparisons of nutrition knowledge and behaviors in adolescents with newly diagnosed and established T1D. This study contrasted adolescents with newly diagnosed and established T1D, using a Nutrition Knowledge Score, 24-hour dietary recall, body mass index, and hemoglobin A1c. Fifty adolescents were enrolled, 25 with newly diagnosed T1D and 25 with established T1D. Nutrition knowledge increased and correlated with lower hemoglobin A1c, showing that nutrition knowledge improves after diagnosis and affects glycemic control.
