Fitzgibbon and colleagues published two reports based on
their Hip-Hop to Health Jr. intervention study, with contrasting
results. In a predominantly Black group of children
(Fitzgibbon et al. 2005), no differences from the control
group were seen immediately after the 14 week intervention
(essentially 10 min moderate to vigorous movement performed
3 times per week). However, 1 and 2 years later,
children who had participated in the intervention displayed
smaller changes in BMI and BMI-Z scores, compared with
the controls. In contrast, in a population where Latino children
predominated, those exposed to the same intervention
did not differ from their control peers on any of the adiposity-related
outcomes, either immediately after the programme
or after 1 or 2 years of follow-up (Fitzgibbon et
al. 2006).
