[Low risk of reproductive disorders among female greenhouse workers--safe work conditions or health selection for the light work?].

BACKGROUND

There are two major potential hazards typical of work in greenhouses: hard physical work or exposure to pesticides. The aim of the study was to investigate whether the work in greenhouse during pregnancy have an adverse effect on its outcome (preterm delivery, spontaneous abortion and birth defects).

MATERIALS AND METHODS

The study was performed in a group of 460 women employed in 14 greenhouses involved in growing vegetables and flowers.

RESULTS

The rate of spontaneous abortions was much elbeit insignificantly higher in the women working in greenhouses during pregnancy than in those employed out of them; that applied mostly to the women performing light jobs in greenhouses. An increased risk of preterm delivery and spontaneous abortion was also observed in women performing greenhouse light jobs. No significantly increased risk of birth defects was observed in children born to women working in greenhouses. Neither was there any relationship between exposure to RD or ED pesticides exposure--and the occurrence of preterm delivery, spontaneous abortion and birth defects.

CONCLUSIONS

No higher risk of pathological pregnancy that could be associated with hard physical work and pesticide exposure was observed. This may result from the fact that women themselves select an appropriate kind of job during pregnancy and a possible removal of women with pathological pregnancy from jobs involving pesticide exposure, as well as from the promotion of biological protection. The greenhouse workers should be aware of the two typical hazards found in greenhouses (hard work and exposure to pesticides) and their potential negative effects on the reproduction. The results of this study warrant the need for further study of the effect of pesticide exposure and work load on the pregnancy outcome.
