There has been a world-wide increase in the incidence of ectopic pregnancies over the last decades. In Norway about 1,500 women are hospitalized every year because of this potentially lethal condition. Several studies have shown that smoking is one of several risk factors for ectopic pregnancies. We wanted to examine whether such an association could be established in a large Norwegian material.
We analysed data from a cross-sectional questionnaire-based study of 9,237 Norwegian women aged 35-49 years. 61.6% responded.
67.4% of the women were present or previous smokers. 301 (3.3%) had experienced an ectopic pregnancy. We found that smokers had a relative risk of 1.5 (95% CI 1.1-1.9) for ectopic pregnancy compared to non-smokers.
Our results support other studies. Identification of risk factors is important in the prevention of ectopic pregnancies. Smoking is a risk factor for ectopic pregnancy that can be reduced through counselling.
在过去几十年中，全球范围内宫外孕的发病率呈上升趋势。在挪威，每年约有1500名女性因这种潜在的致命疾病而住院。多项研究表明，吸烟是宫外孕的几个危险因素之一。我们想研究在大量挪威人群中是否能证实这种关联。
我们分析了一项基于问卷调查的横断面研究的数据，该研究涉及9237名年龄在35至49岁之间的挪威女性。61.6%的人做出了回应。
67.4%的女性目前吸烟或曾经吸烟。301人（3.3%）曾经历过宫外孕。我们发现，与不吸烟者相比，吸烟者患宫外孕的相对风险为1.5（95%置信区间1.1 - 1.9）。
我们的结果支持其他研究。识别危险因素对预防宫外孕很重要。吸烟是宫外孕的一个危险因素，通过咨询可以降低这一风险。
