本文对67名接触二甲基甲酰胺(简称DMF)的已婚女工及132名已婚对照女工月经状况调查的结果,发现接触组女工的月经异常发生频率(29.83%)显著高于对照组(16.67%)。按带环与否分层分析的结果,去除带环因素的影响后,接触DMF 女工的月经异常发生频率仍显著高于对照组。月经异常的发生频率有随着接触浓度的增高而增高的趋势。
In this paper, we investigated the monthly menstrual status of 67 women workers exposed to dimethylformamide (DMF) and 132 married women and found that the frequency of menstrual abnormalities (29.83%) in the exposed group was significantly higher than that in the control group 16.67%). According to the results of stratified analysis by band or not, the frequency of menstrual abnormalities exposed to DMF female workers was still significantly higher than that of the control group after removing the influence of banding ring factors. The frequency of abnormal menstruation tends to increase with increasing contact concentration.
