Data Interpretation IssuesThe survey is conducted using scientific telephone survey methods. Both cell phones and land lines are included. Excluded are adults living in group quarters with a central phone system such as college dormitories, nursing homes, military barracks, and prisons. Results have been weighted to the adult population by age, gender, race, education, marital status, home ownership, telephone source (landline versus cell phone), and county of residence.
Why Is This Important?The percentage of obese adults is an indicator of the overall health and lifestyle of a community. Obesity increases the risk of many diseases and health conditions including heart disease, Type 2 diabetes, cancer, hypertension, stroke, liver and gallbladder disease, respiratory problems, and osteoarthritis. Losing weight and maintaining a healthy weight help to prevent and control these diseases. Being obese also carries significant economic costs due to increased healthcare spending and lost earnings.
