Girls were separated into groups determined by the median age (9.5 years) of the sample. ^aNutritional status was derived from body mass index z-scores and related to UK clinical references. ^†Pair-wise comparisons showed that Bangladeshis were significantly different from each group living in the UK, but no other groups were significantly different from each other.
