 You will also receive a food poster and survey guide after your first study visit. You will use these to participate in 2 unscheduled telephone interviews within the next month. Each interview will take about 30 minutes. At the beginning of the interview, the interviewer will ask if the time is convenient for you, or if you need to reschedule the call for another time when you are available. During these interviews, you will be asked questions about your health and your diet and exercise behaviors.
