Health survey data are an important and efficient source of information for policy makers and administrators. But caution is warranted: surveys do not show cause-and-effect relations, and they are no substitute for randomized controlled experimentation in predicting behavior. The variety of surveys--governmental and private--is increasing, and both methodology employed and interpretation of results can be improved in suggested ways.
健康调查数据对于政策制定者和管理人员而言是重要且高效的信息来源。但需谨慎：调查无法显示因果关系，在预测行为方面也不能替代随机对照试验。政府和私人开展的各类调查日益增多，其采用的方法及结果解读都可按建议方式加以改进。
