Background/Objective: In Wales, approximately one in eight 45 year olds are obese. The aim of this cross-sectional study was to examine the association between childhood obesity and modifiable population level risk factors, after accounting for deprivation.
Methods: A review of the literature identified population level risk factors including: a healthy childcare setting; the local food environment; accessible open space, community safety and crime. Data for the risk factors were matched by each of the twenty-two Local Authorities in Wales to each child in the Wales Childhood Measurement Programme (20122017) (n=129, 893, mean age 5.0 years, standard deviation 0.4 years). Multivariable logistic regression was used to identify associations with childhood obesity.
Results: After adjusting for deprivation, significant associations were found between childhood obesity and percentage of land available as accessible open space OR 0.981 (95% CI: 0.973 to 0.989) P<0.001) and density of fast food outlets OR 1.002 (95% CI: 1.001 to 1.004, P=0.001). No other population level risk factors were related to childhood obesity.
Conclusion: This cross-sectional study found a decreased odds of obesity in areas with more accessible open space and an increased odds of obesity in areas with a higher density of fast food outlets per 100,000 population.
