The prevalence of obesity has increased greatly in the last 30 years. Intensified urban landscapes have created environments that facilitate rising obesity rates. The level of unhealthy food consumption and physical activity accessibility has become imbalanced within the built and social environments of individuals. The term obesogenic environment has been used to describe the increased exposure to obesity, based on the characteristics of the surrounding environment. Previous academic literature has attempted to measure the contribution of obesogenic environment exposure to obesity health outcomes. The key aim of this research is to measure the correlation between obesogenic environments and BMI outcomes of New Zealand school children aged 5-14. Part 1 of this research method considered all children aged 5-14 sampled in the New Zealand Health Survey (NZHS) 2013/2014. Linear regression analysis was used to determine the correlation between BMI and selected NZHS participant responses; the key analysis in part 1 was the correlation between BMI and participants mode of transport to and from school. Part 2 of this research method focused on the New Zealand city of Hamilton. The research method used NZHS data to measure participant exposure to obesogenic environments based on the health responses given by participants. Geospatial network analysis was used to determine the NZHS participant’s home, route and school environments. Obesogenic environment exposure was defined by the Hamilton food and physical environment attributes contained within euclidean buffer zones created around the participant’s home, route and school environment. Linear regression analysis was then used to determine the geospatial correlation between the participant’s environment exposure and BMI outcomes. The results of this research method suggest that participant’s exposure to obesogenic environments did not contribute to obesity health outcomes, based on the lack of statistical evidence provided by the linear regression analysis.
