Trial aims and objectives
The main aim is to assess the clinical and cost-effectiveness
of the 12-month childhood obesity prevention intervention
programme, developed and refined in the BEACHeS study,
using usual practice in primary schools as the comparator.
Intervention effects will be examined at 3 and 18 months
post-intervention completion. Cost-effectiveness of the
intervention will be assessed from a societal perspective.
In addition, differences in intermediate and final outcomes
will be explored by sex, ethnicity, socioeconomic status
and weight status. We will also use a variety of methods to
describe the implementation of, and adherence to, intervention
components [17].
