The 2013 BRFSS
is based on 491,000 interviews conducted
across all 50 states, the District of Columbia, Puerto Rico, and Guam. The
2013 data on health risk behaviors, clinical preventive health practices, and
health care access (primarily related to chronic disease and injury) come from
a representative sample of non-institutionalized adults aged 18 years and
older in each state.
The 2013 BRFSS data continue to reflect the
changes initially made in 2011 in weighting methodology (raking) and the
addition of cell phone-only respondents. The data allow for state-to-state
and state-to-nationwide comparisons, and the state-specific data provide a
sound basis for developing and evaluating public health programs, including
programs targeted to reduce disparities in addressing health risks.
