Behavioral risk factor (BRF) telephone surveys were conducted by 28 states and the District of Columbia from April 1981 through October 1983 to obtain baseline prevalence estimates for risk factors associated with the leading causes of death among adults. A supplemental survey was conducted to cover the remaining states (except Hawaii) in order to provide individual states with national-level data for comparison purposes. The complex sampling designs and variable sampling rates among state surveys required the computation of sample weights before estimates on a national level could be made. Estimates from the combined individual surveys are similar to those obtained from more expensive in-person interviews. The BRF national prevalence estimate of chronic heavier drinking is 8.7 percent, equivalent to the 1979 National Institute on Alcoholism and Alcohol Abuse (NIAAA) estimate of 9 percent. The BRF estimate of 31.5 percent for current smokers compares closely with the 32.6 percent estimated by the 1980 Health Interview Survey. Despite recognized technical limitations, this type of telephone survey can be a practical and affordable source of information both for initially gathering prevalence data and for monitoring trends in the prevalence of behavioral risk factors of public health concern.
1981年4月至1983年10月期间，28个州和哥伦比亚特区开展了行为危险因素（BRF）电话调查，以获取与成年人主要死因相关的危险因素的基线患病率估计值。为了向各个州提供国家级数据以供比较，还对其余州（夏威夷除外）进行了补充调查。由于各州调查的抽样设计复杂且抽样率各不相同，因此在得出全国层面的估计值之前，需要计算样本权重。综合各项单独调查得出的估计值与通过更昂贵的面对面访谈得出的估计值相似。BRF对慢性重度饮酒的全国患病率估计为8.7%，与1979年美国国立酒精滥用与酒精中毒研究所（NIAAA）9%的估计值相当。BRF对当前吸烟者的估计患病率为31.5%，与1980年健康访谈调查估计的32.6%非常接近。尽管存在公认的技术局限性，但这种电话调查对于初步收集患病率数据以及监测公共卫生关注的行为危险因素患病率趋势而言，可能是一种实用且经济的信息来源。
