Cardiorespiratory effects of project energize: a whole-of region primary school nutrition and physical activity programme in New Zealand in 2011 and 2015.

The findings from this study support the continuation of the delivery of Project Energize in the Waikato region of New Zealand, as cardiorespiratory fitness scores in 2015, compared to 2011, were improved, particularly for lower SES schools and for Māori children. Ethnically diverse populations, schools with higher deprivation and girls, continue to warrant further attention to help achieve equity.
