You may complete the questionnaire online using the web site address (Click here), username and password provided in the invitation letter and/or by site staff. Alternatively, scannable paper forms may be provided if preferred. In either case, your responses to the questionnaire will be secure and anonymous, and no identifiable information will be present. The questionnaire will collect data pertaining to your general information (i.e., age, gender, race, employment, etc.), health conditions, pregnancy history, sleeping ability, body shape and other body characteristics, foods you eat, and physical activity. All of this information is necessary in order to fully evaluate the many lifestyle and health factors. Your care and attention to providing complete and accurate information will assist us in learning more about parental and child health.
