BRFSS Refined to Include Data from Cell Phone Users
Refinements to the Behavioral Risk Factor Surveillance System (BRFSS) to include data received from cell phone users facilitates the inclusion of a broader demographic and ultimately provides a better reflection of the nation’s health status.
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).
