In a British population cigarette smoking during pregnancy increased the late fetal plus neonatal mortality rate by 28% and reduced birth weight by 170 g, and these differences persist even after allowing for a number of "mediating" maternal and social variables. A change in smoking habit by the end of the fourth month of pregnancy places a mother in the risk category appropriate to her changed habit. This evidence should have important implications for health education aimed at getting pregnant mothers to give up smoking.
在英国人群中,孕期吸烟使胎儿晚期及新生儿死亡率增加了28%,出生体重减轻了170克,即使考虑了一些“中介”性的母亲和社会变量,这些差异依然存在。在怀孕第四个月末改变吸烟习惯会使母亲处于与其改变后的习惯相应的风险类别中。这一证据对于旨在让怀孕母亲戒烟的健康教育应具有重要意义。
