Abstract

Objective: National body fatness (BF) data for English South Asian and Black children use BMI, which provides inaccurate ethnic comparisons. BF levels and time trends in the English National Child Measurement Programme (NCMP) between 2007 and 2013 were assessed by using ethnic‐specific adjusted BMI (aBMI) for South Asian and Black children. / Methods: Analyses were based on 3,195,323 children aged 4 to 5 years and 2,962,673 children aged 10 to 11 years. aBMI values for South Asian and Black children (relating to BF as in White children) were derived independently. Mean aBMI levels and 5‐year aBMI changes were obtained by using linear regression. / Results: In the 2007‐2008 NCMP, mean aBMIs in 10‐ to 11‐year‐old children (boys, girls) were higher in South Asian children (20.1, 19.9 kg/m2) and Black girls, but not in Black boys (18.4, 19.2 kg/m2) when compared with White children (18.6, 19.0 kg/m2; all P < 0.001). Mean 5‐year changes (boys, girls) were higher in South Asian children (0.16, 0.32 kg/m2 per 5 y; both P < 0.001) and Black boys but not girls (0.13, 0.15 kg/m2 per 5 y; P = 0.01, P = 0.41) compared with White children (0.02, 0.11 kg/m2 per 5 y). Ethnic differences at 4 to 5 years were similar. Unadjusted BMI showed similar 5‐year changes but different mean BMI patterns. / Conclusions: BF levels were higher in South Asian children than in other groups in 2007 and diverged from those in White children until 2013, a pattern not apparent from unadjusted BMI data.
