*Total n=15 039.
†Child weight status based on ethnic-adjusted BMI and categorised according to UK90 clinical reference standard.
‡Parental weight status was categorised using BMI calculated from parental self-reported weight and height as follows: ‘underweight’ (BMI <18.5 kg/m²), ‘healthy weight’ (≥18.5 to <25 kg/m²), ‘overweight’ (≥25 to <30 kg/m²) or ‘obese’ (≥30 kg/m²), except for South Asian adults where ‘overweight’ is ≥23 to <27.5 kg/m² and ‘obese’ is ≥27.5 kg/m².
§Ethnic background of the child was obtained from parental report at the first MCS interview and categorised using UK 2011 Census categories.
