Description

The Behavioral Risk Factor Surveillance System (BRFSS) is an annual statewide telephone surveillance system designed by the Centers for Disease Control and Prevention (CDC). BRFSS monitors modifiable risk behaviors and other factors contributing to the leading causes of morbidity and mortality in the population. New York State's BRFSS sample represents the non-institutionalized adult household population, aged 18 years and older. Although the overall number of respondents in the BRFSS is more than sufficiently large for statistical inference purposes, subgroup analyses can lead to estimates that are unreliable. Interpreting and reporting weighted numbers that are based on a small, unweighted number of respondents can mislead the reader into believing that a given finding is much more precise than it actually is. The BRFSS follows a rule of not reporting or interpreting percentages based upon a denominator of fewer than 50 respondents (unweighted sample). Both a csv and sas data files are available.

Notes
Notes
Researchers agree to: 1. Use the data for statistical reporting and analysis only; 2. Make no attempt to re-identify survey respondents by any means including but not limited to linking the data with any other data set that may provide the ability to identify a participant in the survey; 3. Produce data tables such that survey respondents' confidentiality is protected; 4. Include a disclaimer that credits any analyses, interpretations, or conclusions reached to the author and not to either NYSDOH or BRFSS, reference the website, year analyzed and date of the download; 5. Use appropriate statistical software capable of analyzing complex sample survey data, for example SUDAAN, STATA, SAS; 6. Suppress reporting of information in instances when reliability of the estimates should be considered: One-half confidence interval is greater than 10, for asymmetric confidence intervals both the lower and upper intervals exceed 10, There are fewer than 50 observations in the denominator or less than 6 in the numerator , or Relative standard error (RSE) is greater than .30
