寿命表法分析二硫化碳对作业女工妊娠概率的影响

The effects of carbon disulphide on pregnancy probability by life table analysis

目的 探讨二硫化碳 (CS2 )对作业女工妊娠概率的影响。方法 用寿命表法 ,分析欲要生育女工每个月经周期的受孕概率及未受孕率。结果 接触组女工未受孕概率明显高于对照组 (P =0 0 0 0 4) ;接触组女工平均受孕时间为4 5 3个月经周期 ,对照组女工平均受孕时间为 3 37个月经周期 (P =0 0 0 2 1)。结论 接触组女工每个月经周期的妊娠概率明显低于对照组 ;CS2

Objective To study the effects of carbon disuphide (CS 2)on pregnant probability. Methods Using life table analysis, to calculate the probabilities of pregnancy and unpreganacy in each menstral cycles of women after contraceptive stoppage with baby desire. Results The probability of pregnancy in exposed group was lower than that in the control and the probability of unpregnancy in exposed group was higher than that in control. There were significant difference between two groups (χ 2=12.66, P=0.000 4 ). The average cycles for getting successful pregnancy offered by life table in exposed group was 4.53 cycles while 3.37 in control group(χ 2=9.48, P =0.002 1). Conclusion It was shown that the abilities of getting a clinically recognized pregnancy were sharply descended in women occupationally exposed to CS 2.
