Women diagnosed with Gestational Diabetes Mellitus (GDM) experience complications that can affect them or their infant. One-half of women with GDM are likely to develop Type 2 Diabetes Mellitus later in life. Creating healthy meals during a pregnancy involves moderating carbohydrate (CHO) intake to 175 grams for normal fetus development using CHO counting and CHO exchanges. Meal quality including total CHO content, can be determined using the Nutrition Facts Label (NFL), but this may be a challenge if pregnant women are not familiar with the NFL. They may have to limit food purchases to foods that stay within their budget and not choose high sugar foods. In 2016, the U.S. Food & Drug Administration announced that the NFL would be updated with a listing of ‘added sugars’ which is helpful in identifying foods with extra sugar. The purpose of this directed project was to create a healthy eating guidebook for low-income women in the United States who have GDM. Objectives were that the guidebook would be easy to read and understand, educate pregnant women about the NFL, and focus on calories, carbohydrates, and added sugars. Content validity was evaluated by five Registered Dietitian Nutritionists. Usability was evaluated by six Long Beach, California women who had or were at risk for GDM and participants in the Women, Infants, and Children program. Results of the pre/post evaluations for content, functionality, layout and design of the guidebook and future application of the final guidebook will be presented.
