本病例对照研究的目的是评估怀孕期间的职业条件是否与早产（PTD）有关。在采取合法的预防措施（退出工作或重新分配工作）后工作条件发生变化的妇女也与工作条件未发生变化的妇女进行了比较。病例（n = 1,242）和对照（n = 4,513）选自加拿大魁北克省1997年1月至1999年3月间单胎分娩的43,898名妇女。他们在交货后接受了电话采访。结果显示，PTD与每天至少3小时的高要求姿势，全身振动，高工作压力合并低或中等社会支持，以及由9种职业条件组成的累积指数有关。PTD的调整优势比从1.0增加到2.0 (p趋势< 0.0001)，而非常PTD的调整优势比从1.0增加到2.7 (
The objective of this case-control study was to evaluate whether occupational conditions during pregnancy are associated with preterm delivery (PTD). Women whose work conditions changed following the use of a legally justified preventive measure (withdrawal from work or job reassignment) were also compared with those whose work conditions did not change. Cases (n = 1,242) and controls (n = 4,513) were selected from 43,898 women who had single livebirths between January 1997 and March 1999 in Quebec, Canada. They were interviewed by telephone after delivery. Results showed association of PTD with demanding posture for at least 3 hours per day, whole-body vibrations, high job strain combined with low or moderate social support, and a cumulative index composed of nine occupational conditions. The adjusted odds ratio increased from 1.0 to 2.0 for PTD (P-trend < 0.0001) and from 1.0 to 2.7 for very PTD (
