DIABETES DATA AND TRENDS HELP |
National surveillance data
National surveillance data allows you to view and monitor the trends and complications of diabetes, such as prevalence, hospitalization, duration of diabetes, etc. in the US over time.
You can access national surveillance data from the homepage, or by clicking the National Surveillance Data option on the navigation bar.
You can monitor the following trends:
- Prevalence
- Incidence and Age at Diagnosis
- Duration of Diabetes
- Treating Diabetes (insulin and oral medication use)
- Diabetes Complications
- Hospitalization
- Preventive Care Practices
- Risk Factors for Complications
- Health Status and Disability
| Viewing information |
When you select a trend to view, for example Prevalence, the system displays a list showing the different ways for viewing the data. For Prevalence, data can be displayed by number of persons, percentage by age, percentage by sex, percentage by race, ethnicity, and sex, etc. When you select a view, the system displays a page that displays the data. The page is divided into the following sections. The system also displays the data sources at the bottom of the page. |
| Viewing graphs |
The Diabetes and Data Trends system uses different types of graphs to depict data. For greater accuracy, the system also displays a table below the graph, thereby removing any guesswork while reading the graph. National surveillance data is displayed using the following different types of graphs. Graph/Chart Type 1 This is a bar graph used to depict differences among similar things.
Graph/Chart Type 2 The horizontal bar chart is used to show differences among similar things, but usually for a series with long labels.
Graph/Chart Type 3 The Line Chart is used for direct comparison and to demonstrate changes over time. The Line Chart is the best way to show multiple trends over a period of time.
Graph/Chart Type 4 This type of graph is used to depict mean and median data.
Graph/Chart Type 5 This is a color-coded bar graph used to depict different data for one entity, for example the prevalence of diabetes among three different age groups in men.
