This study compared health behavior variables for all US households and households with telephones to measure the potential impact of telephone coverage on estimates from telephone surveys.
Data were derived from the 1991 through 1994 version of the National Health Interview Survey.
Ninety-five percent of respondents lived in households with telephones. Differences in health indicators were small (< 1%) in comparisons between all households and those with telephones. Results were similar when only respondents below the poverty level were included.
Telephone noncoverage effects appear to be small, supporting the use of telephone surveys for health risk behavior surveillance with most population groups.
本研究比较了美国家庭总体与有电话家庭的健康行为变量，以衡量电话覆盖情况对电话调查估计结果的潜在影响。
数据来源于1991年至1994年版的《国家健康访谈调查》。
95%的受访者生活在有电话的家庭。所有家庭与有电话家庭之间健康指标的差异很小（<1%）。仅纳入贫困线以下受访者时，结果相似。
电话未覆盖的影响似乎很小，这支持了对大多数人群进行健康风险行为监测时使用电话调查。
