The objective of this study was to identify major occupational factors that were significantly correlated with back pain in pregnant women working in higher education, health care and service areas. A total of 73 working pregnant women were surveyed using questionnaires specifically designed for evaluating correlations between occupational factors and severity of back pain; 37 women were interviewed at both 20 and 34 weeks of pregnancy, 17 at 20 weeks only, and 19 were interviewed at 34 weeks only. "Rest breaks allowed" and "job autonomy" were negatively correlated with severity of back pain at 20 weeks of pregnancy. "Staying in a confined area" and "having restricted space" were positively correlated with severity of back pain at 34 weeks of pregnancy. The study suggests that allowing pregnant women to take more rest breaks and to have more job autonomy may reduce the severity of back pain during early pregnancy, and that allowing movement outside the working area and providing less restricted space may reduce back pain during late pregnancy.
本研究的目的是确定与在高等教育、医疗保健和服务领域工作的孕妇背痛显著相关的主要职业因素。使用专门设计的问卷对73名在职孕妇进行了调查，以评估职业因素与背痛严重程度之间的相关性；37名妇女在怀孕20周和34周时接受了访谈，17名仅在怀孕20周时接受了访谈，19名仅在怀孕34周时接受了访谈。“允许休息”和“工作自主性”与怀孕20周时的背痛严重程度呈负相关。“待在封闭区域”和“空间受限”与怀孕34周时的背痛严重程度呈正相关。该研究表明，允许孕妇多休息并给予更多工作自主性可能会减轻怀孕早期的背痛严重程度，而允许在工作区域外活动并提供限制较少的空间可能会减轻怀孕后期的背痛。
