Determination of clinical parameters
We collected basic information from all subjects (age, birth weight, height, and weight) and calculated the BMI using height and weight. We also interviewed the parents of the children to collect information on maternal age, gestational age, delivery mode, feeding patterns, maternal educational level, maternal smoking history, maternal drinking history, paternal educational level, paternal smoking history, and paternal drinking history. Children in the C-ASD group were assessed with the CARS and ABC. All children were evaluated with CEBQ.
