寿命表法分析二硫化碳对作业女工妊娠概率的影响

LIFE TABLE ANALYSEING THE EFFECTS OF EARBON DISULPHIDE ON PREGNANCY PROBABILITY

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＝ ０．０００４）；接触组女工平均妊娠时间为 ４．５３月经周期，对照组女工平均妊娠时间为３．３７ 月经周期（Ｐ＝ ０．００２１）。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 作业女工获得一次临床可识别妊娠的概率明显降低。

Objective For the effects of carbon disulphide (CS 2) on pregnancy probability.Method Using life table analysises calculated the probabilities of pregnancy and unpregnancy in each menstral cycles of women after stoping use contraceptive and wanting to have a baby.Result 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=0.0004).The average meastral cycles offered by life table in exposed group was 4.35 cycles while 3.37 in control group (χ 2=9.48,P=0.0021).Conclusion It was shown that the abilities of getting a clinically recognized pregnancy were sharply descended in women occupationally exposed to CS 2.
