The main diet survey (called the ASA24) will ask you to report what you ate and drank over the previous day.  This is the survey you will be asked to complete a few times over the year.  It will ask you to report all foods and drinks for your meals and snacks, as well as any supplements (e.g., vitamins), as well as what time you ate/drank, where you consumed them (e.g., home, restaurant), and a few other questions.  The survey may also ask you a few extra questions to help prompt reporting of things people sometimes forget, like adding toppings to sandwiches and salads.   

The main activity survey (called the ACT24) will ask you to report what activities you did over the previous day.  This is the other survey you will be asked to complete a few times over the year (in addition to the diet one described above).  It will ask you to choose activities that reflect what you did for all hours of your day, such as sleeping, getting ready in the morning, getting to work, and so on.  It will ask you some additional questions depending on the activity, such as how much of the activity was spent sitting vs. standing, and the level of exertion (e.g., for activities like sports).   

The last set of diet and activity surveys will ask you about your diet and activities for the past year.  The diet survey (called the CDHQ-III) will ask you how often you ate or drank certain foods and drinks, and how much you usually ate/drank them.  The activity survey (called the PYTPAQ) will ask you to report the activities you engaged in (e.g., work, snowshoeing, gardening), how often and for how long you did the activities (e.g., gardening for 4h per day, 1 day per week in the summer, for 4 months), and the level of exertion (e.g.,  didn’t increase your heart rate, or caused your heart rate to increase a lot).
