Despite the large sample size and diversity of facilities surveyed, a number of limitations to our study exist.
In Pennsylvania, population density, intersection density, diversity of facilities, and certain types of facility density inside obesity clusters were significantly lower compared to areas outside the clusters.
The majority of the built environment variables, including population density, intersection density, diversity of facilities, and most facility densities, were consistently higher compared to outside of clusters.
Eleven objective built environment variables were created using ArcGIS 9.3 software (ESRI, Redland, CA) and employed methods described more fully in earlier work [ 42]: population density, intersection density, diversity of facilities, and eight facility density variables.
A 2006 InfoUSA™ facility database, containing North American Industrial Classification System (NAICS) codes and longitude and latitude for each facility [ 48] was used to create the diversity of facilities and facility density variables within each buffer.
Using five categories of facilities (food, retail, services, cultural/educational, and physical activity), diversity of facilities was calculated with an entropy formula [ 49, 50] that estimates the mixture of facility types.
For instance, the greater diversity of the facilities in Kenya in terms of size and scope of services may be reflective of the local markets in which they compete, and may also be one reason for the somewhat greater value placed on branding in Kenya.
In California and Massachusetts, population density, intersection density, and diversity and density of facilities in two higher physical activity clusters were significantly greater than in neighborhoods outside of clusters.
Nerd tourists can now access a diversity of museums, launch facilities and geek-friendly attractions without driving farther than a few hours from Dulles International.
Therefore, study settings were purposively selected to demonstrate the effectiveness of the CCSAS Multimedia Training Tool in a diversity of humanitarian settings, health facility levels, and geographical regions.
Clearly, one in which there were small class sizes, contented and well-paid teachers, a range and diversity of well-taught subjects and facilities suited to the job of engaging young enquiring minds.
