RESUMO
Paracetamol is the most commonly used over-the-counter drug in pregnancy. It is generally considered to be safe, but prolonged antenatal exposure has been associated with offspring short- and long-term morbidity. Our aim was to describe the pattern of paracetamol use with a focus on frequent ingestion (more than once a week), 3 months before and in early pregnancy. In this cohort, 8650 pregnant women responded to a web-based clinical questionnaire that included questions about drug use. Paracetamol was the most used drug before and in early pregnancy (35.2% and 6.5% of respondents, respectively). The proportion of frequent users decreased from 3.9% before to 0.9% in early pregnancy. Frequent paracetamol use was associated with smoking, co-morbidities, body mass index ≥ 25 kg/m(2), unplanned pregnancy, no education and inability to understand Danish. A significant decrease in the proportion of women with any paracetamol use in early pregnancy was noted after access to large packs was restricted by legislation.

OBJECTIVE: The risk of fetal death increases steeply after 42 gestational weeks. Since 2009, Denmark has had a more proactive policy including prevention of prolonged pregnancy, and early intervention in women with diabetes, preeclampsia, high body mass index and of a higher age group. The aim of this study was to describe the development in fetal deaths with this more proactive birth induction practice, and to identify and quantify contributing factors for this development. DESIGN: National cohort study. SETTING: Denmark. PARTICIPANTS: Delivering women in Denmark, 1 January 2000 to 31 December 2012. OUTCOME MEASURES: Stillbirths per 1000 women at risk (prospective risk of stillbirth) and per 1000 newborn from 37 and 40 gestational weeks, respectively, through the study period. RESULTS: During the study period, 829,165 children were live born and 3770 (0.45%) stillborn. Induction of labour increased from 12.4% in year 2000 to 25.1% in 2012 (p<0.001), and the percentage of children born at or after 42â weeks decreased from 8.0% to 1.5% (p<0.001). Through the same period, the prospective risk of stillbirth after 37â weeks fell from 0.70 to 0.41/1000 ongoing pregnancies (p<0.001), and from 2.4 to 1.4/1000 newborn (p<0.001). The regression analysis confirmed the inverse association between year of birth and risk of stillbirth. The lowest risk was observed in the years 2011-2012 as compared with years 2000-2002 with a fully adjusted HR of 0.69 (95% CI 0.57 to 0.83). The general earlier induction, the focused earlier induction of women with body mass index >30, twins, and of women above 40â years and a halving of smoking pregnant women were all independent contributing factors for the decrease. CONCLUSIONS: A gradually more proactive and differential earlier labour induction practice is likely to have mainly been responsible for the substantial reduction in stillbirths in Denmark.
