Like me, like you – relative importance of peers and siblings on children’s fast food consumption and screen time but not sports club participation depends on age

N, number of observations of children
P < 0.001 for all
Each child from a sibling pair was randomly assigned to be the target child or sibling
Linear mixed models adjusted for age and sex of the target children, age of the sibling, sex of the sibling pair, birth order, parental education, and country and family ID as random effects
In model 1e the age difference between the sibling is ≤2.7 years. In model 1f the age difference between siblings is > 2.7 years
