- OBJECTIVES
The aim of this study was to examine the association of prenatal environmental exposure and pregnancy outcomes.
METHODS
Self-administered questionnaire survey was conducted for pregnant women with gestational age of 16-18 weeks, who visited the outpatient department of Dankook University Hospital from May 1995 to June 1999. Of all 1170 women, 762 women answered the questionnaires and the response rate was 65 %. Among them, 471 cases which has delivered at our hospital were included in this study.
RESULTS
Comparing the environmental risk factors and the pregnancy outcomes, there was an association between delivery of small for gestational age infants and the ingestion of herb medicine and caffeine-containing nutritional beverages. Pregnant women with occupation were more likely exposed to environmental tobacco smoking, to ingestion of nutritional drinks and green teas, to use of video display terminals and to diagnostic radiation.
CONCLUSIONS
We could get precise information from prospectively conducted questionnaire study. It is necessary to extend the study population to verify the influence of prenatal environmental factors on pregnancy outcomes.

- This paper focuses on the origin of the concepts of occupational exposure limit, and traces the history and development of thoughts and regislations of various countries and organizations concerning the founding principles upon which it is based. The concepts of establishing standards for occupational chemicals in workplace air constitute a social consensus or agreement about acceptable levels of occupational hygiene. The level of scientific development of a country and the discussion of experts in the field of occupational health play an important role. The physician in occurational health has to be especially concerned to discover and estimate the risks to anyone particularly susceptible to exposures within the hygienically acceptable conditions.
