Regression models were adjusted for weekend, season, child's sex, age at measurement, child's ethnicity, maternal BMI, main respondent's age at the birth of the cohort member, maternal socioeconomic circumstances, main respondent's education, household annual income, cars or vans (regular use), lone parenthood status, number of children in the household, Country by (index of multiple deprivation) interaction and urban/rural indicators.
*These values/increments approximate to one SD of these measures.
BMI, body mass index; FFMI, fat free mass index; FMI, fat mass index; Min, minutes; MVPA, moderate-to-vigorous physical activity; PA, physical activity.
