Table 3 The relative importance of peer and sibling behavior for all children, and stratified by target children’s sex, sibling pair sex and age difference between siblings

From: 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

 Fast food consumption (frequency/week)Screen time duration (hours/week)Sports club duration (hours/week)

  1. N, number of observations of children
  2. P < 0.001 for all
  3. Each child from a sibling pair was randomly assigned to be the target child or sibling
  4. 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
  5. 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
