The Arizona Twin Project is a research project involving the study of twins, both identical and fraternal, and the resilience they develop to physical and mental illnesses later on in life by studying several factors such as home environment, sleeping patterns, lifestyle (academics as well as extra-curricular activities), and eating habits. This project specifically focused on the nutrition and food intake by analyzing data from 3 days of food diaries from 10 families. In order to fully assess nutrition and food intake, a coding system was created to properly analyze the data that was provided in the food diaries by the parents. The coding system was generated from a combination of two of the most accurate coding methods used in nutrition, known as the 24 hour food recall and diary/food record methods. The measures that were coded were: most food group consumed, caloric intake, total fat consumption, total protein consumption, total carbohydrate consumption, total sugar consumption, total fiber consumption, frequency of eating, and homemade versus fast food. Once the nutritional data from all 10 families was coded, the output information was analyzed using SPSS to provide summary and descriptive statistics as well as correlations among the codes, and demographics of the sample.
