There are a number of limits to this study. The use of zip code centroid to determine a good kid’s https://datingranking.net/local-hookup/charlottetown/ quarters and fast-food socket could lead to slight miscalculations in the means to access dimensions.

As this is an enthusiastic observational investigation, it is hard to draw causal inferences regarding studies, therefore, the results is limited to connectivity ranging from activities. One of several problems with observational education is the fact off confounding. In our investigation i managed getting deprivation and you will gender, but inability in order to effectively handle for other affects could lead to confounding, by which apparent relationships with the environmental components being mentioned try, in reality, on account of public or cultural facts or other ecological situations. 39 Eg, some research has discover a link anywhere between pounds position and you may supply so you’re able to green area. forty Additionally, the model didn’t take into account ethnicity, although it is famous any particular one ethnic minority organizations was known to get more vulnerable so you can developing obesity. 41 Research has shown you to timely-dining sites be much more commonplace in components that have highest concentrations out-of ethnic fraction organizations when comparing to Caucasian. 19 In the end, it has also been found your dining ecosystem beyond one out of timely-restaurants retailers (i.e. supermarkets) is generally a contributing basis to a lot of restaurants consumption. 42
