The information below is designed help readers gain a basic understanding of the problem, the scale of the epidemic in Lane County, and the community level solutions recommended by the U.S. Centers for Disease Control and Prevention (CDC).

Definitions

Obesity: Body Mass Index (BMI) of 30 or higher (BMI ≥30, or ~ 30 lbs. overweight for 5’ 4” person).  A condition in which excess fat has accumulated to the extent that it may negatively impact on one’s health, leading to reduced life expectancy and/or increased health problems.

Body Mass Index (BMI): A measure of an adult’s weight in relation to his or her height, specifically the adult’s weight in kilograms divided by the square of his or her height in meters.

Target Behaviors for Change

The CDC focuses on six target behaviors for the prevention of obesity and other chronic conditions:

  1. Increase physical activity
  2. Increase consumptions of fruits and vegetables
  3. Increase breastfeeding initiation, duration, and exclusivity
  4. Decrease consumption of sugar sweetened beverages
  5. Decrease consumption of high energy dense, nutrient poor, foods
  6. Decrease television viewing

But we know that changing individual behavior, while important, is not enough. The scope of the problem and our limited resources mean we will have greater impact by changing the environments and conditions to make healthy choices easier for everyone.
