In this study, the authors analyzed the association between video display terminal (VDT) use before and during the three trimesters of pregnancy and risk of small-for-gestational-age (SGA) birth in a case-control study. The cases for this study were 555 women who delivered SGA births. The controls were 1966 women who gave birth at term to healthy infants of normal weight. In terms of the length of exposure, the odds ratios (OR) of SGA birth were 1.2 for less than one hour and 1.3 for between two and 20 hours per week. For higher usage (more than 20 hours per week), the OR was 1.2 (95% CI: [Confidence Interval] 0.9-1.7). The authors conclude that this study does not show any association between VDT use and risk of SGA birth.
在这项研究中，作者在一项病例对照研究中分析了孕期前三个月及孕期使用视频显示终端（VDT）与小于胎龄儿（SGA）出生风险之间的关联。该研究的病例为555名分娩出小于胎龄儿的女性。对照为1966名足月分娩出体重正常健康婴儿的女性。就暴露时长而言，每周使用VDT少于1小时的小于胎龄儿出生的比值比（OR）为1.2，每周使用2至20小时的OR为1.3。对于更高的使用量（每周超过20小时），OR为1.2（95%置信区间：[置信区间]0.9 - 1.7）。作者得出结论，这项研究未显示出VDT使用与小于胎龄儿出生风险之间存在任何关联。
