title: [Verification of smoking habits in group studies by anamnesis or determination of serum thiocyanate level?].
abstract: In an unselected series of 336 patients of our clinic for occupational diseases a standardized questionnaire on respiratory symptoms and measurements of lung function (spirometry, body plethysmography, flow-volume-curve) were used to study the relations of these results to smoking habits evaluated by questionnaire or thiocyanate level. Statistical elaboration revealed closer connections between anamnestic data on smoking habits and respiratory impairment than between the latter and thiocyanate level. In conclusion anamnestic data on smoking habits are more reliable than thiocyanate measurements in occupational field studies.
