Behavioral Risk Factor Surveillance Survey: 2019

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.

行为风险因素监测系统（BRFSS）系由疾病控制与预防中心（CDC）设计的一项年度全州范围的电话监测系统。该系统旨在监测可改变的风险行为及其他导致人群中常见疾病和死亡的主要原因。纽约州的BRFSS样本代表了非机构化成年家庭人口，年龄在18岁及以上。尽管BRFSS的受访者总数对于统计推断而言已足够庞大，但子群体分析可能导致不可靠的估计。基于少量未加权受访者计算出的加权数值的解释和报告可能会误导读者，使他们误以为某一发现比实际情况更为精确。BRFSS遵循一项原则，即不报告或解释基于少于50名受访者（未加权样本）的百分比。csv和sas数据文件均可用。如需更多信息，请访问http://www.health.ny.gov/statistics/brfss/。
