The Pacific population has been described as youthful, with a median age of 21 years old. The health and wellbeing of young Pacific people is affected by the growing obesity epidemic, particularly as Pacific peoples have the highest prevalence of obesity in New Zealand (68% compared to 33% of the total population). There is no known public health intervention that has proven to be successful, sustainable or culturally relevant. This study aims to develop a Pacific youth health empowerment model and Pacific health research approach. The health model and research approach aims to empower and train Pacific youth as key researchers working collectively as a catalyst of social change within their own communities. The model draws uniquely on the social, cultural and historical factors that impact on the obesogenic environment. This work will contribute important knowledge to international obesity research and promote new ideas advocating obesity policy control.
