2.2. Dietary Assessment
AIDS
The child’s diet was assessed at ages 9, 18, 42, and 60 months using a telephone-administered 3-day 24 h recall with parents. Trained nutritionists contacted the parents on three non-consecutive days, including two weekdays and one weekend day. The parents were asked to recall all food and beverages the child had consumed in the previous 24 h; prior to the recall interview, the parents were provided with visual aids to assist with the estimation of portion size. In order to limit bias, the parents were contacted unscheduled (97%). One or two interviews with parents were scheduled for children that spent three days or more with another caregiver (e.g., daycare or grandparent). In case of a scheduled interview, the other caregiver, e.g., daycare or grandparent, was asked to record the child’s food and beverage intake using a purpose-designed food diary and deliver it to the parents; this was used by the parents during the recall interview. Trained researchers coded the data using the 2007 Australian Food and Nutrient Database (AUSNUT) Database [
