Age and sex-adjusted SDS were calculated by comparison with the WHO 2006 growth standard up to age 5 years and the WHO 2007 growth reference from age 5+ years.
UK data were adjusted for survey design; hence, SE and not SD are reported.
ABIS, All Babies in South East Sweden Study; BMI, body mass index; MCS, millennium cohort study; NCGSS, National Children Growth Standard Survey; SDS, SD score.
