Using Geographical Convergence of Obesity, Cardiovascular Disease, and Type 2 Diabetes at the Neighborhood Level to Inform Policy and Practice

PEER REVIEWED

Four versions of a map of western Adelaide are shown. The map is divided into 490 regions. On the first map, mean BMI is shown for each region in 4 categories: 24.0 to 27.8, 27.9 to 29.6, 29.7 to 31.4, and 31.5 to 36.0. Most of the regions are in the higher categories, but the lowest categories are mostly in the west. The second map shows the percentage of CVD event diagnosis in 4 categories: 0 to 2.78%, 2.79% to 7.58%, 7.59% to 15.38%, and 15.39% to 50.00%. The regions in the highest category are in the east. The third map shows the percentage of type 2 diabetes in 4 categories: 0 to 5.26%, 5.27% to 12.00%; 12.01% to 21.74%, and 21.75% to 44.4%. The regions in the highest category are also in the east. The fourth map shows socioeconomic status in 3 categories: high, moderate, and low. The regions in the high category are mostly in the west and south, while the regions in the low category are concentrated in the northeast.

Three versions of a map of western Adelaide are shown, one for BMI, one for CVD, and one for type 2 diabetes. The map is divided into 490 regions; each region is shown as either having no significant difference for BMI, CVD, or type 2 diabetes or having a hot spot or cold spot at either 90%, 95%, or 99% confidence. The first map shows BMI hot spots mostly in the northern section and cold spots in the west and southwest. The second map shows cold spots concentrated in the southwest and hot spots mostly in the east. The third map shows type 2 diabetes hots spots concentrated in the central-eastern area and cold spots in the southwest and southeast.
