¹SES-Index: Components included net family income (dividing the sum of net income through the sum of the family’s members’ weighting), maternal education, and parental employment, each component can take values up to seven, and the total SES-Index ranges between 3 and 21 and is categorized as follows: low: 3–8, medium: 9–14, high: 15–21
*16 of 191 children were missing data from the parental survey
