Behavior Risk Factor Surveillance System

The BRFSS telephone survey has been traditionally done with people using land lines. However, in recent years, an increasing number of people are only using cell/mobile phones. CDC recognized the need to include cell phone users in our survey in order to obtain data that better represents the diverse populations in our society (nation).

Because BRFSS has expanded and improved the way we gather and process information, new data cannot be accurately compared to previous findings line by line (point by point).

However, as we move forward, the survey results will better reflect the health status of the people of the United States.
