The prevalence of substance abuse in women who become pregnant is similar to that of the general population, resulting in a high fetal exposure rate during the most vulnerable period regarding neurodevelopment and organogenesis. The present study was intended to assess the level of prenatal exposure to tobacco, alcohol or illicit drugs in the city of Málaga (Spain). It was designed as a cross-sectional study, and based on the anonymous self-reports of participants. A total of 451 pregnant women were recruited in the first, second or third trimester. The prevalence in each of the quarters respectively was 21.2%, 18.5% and 13.3% for smoking, 40.7%, 23.1% and 17.1% for alcohol and 4.8%, 1.9% and 1.2% for cannabis. We also found that a higher educational level was associated with a lower consumption of tobacco (RR 0.659 [0.537-0.810] p<0.0001) and greater exposure to alcohol (RR 1.87 [1.30-2.69] p<0.0007). These results, particularly in regard to alcohol intake, are sufficiently alarming to alert obstetric care providers about the need to implement preventive measures.
The prevalence of alcohol intake in women who become pregnant is similar to that found in the general population, especially in cases of unplanned pregnancies. Consequently, foetal exposure is high during the period of maximum vulnerability. The present study was carried out to determine the prenatal level of exposure to alcohol in Málaga, a Mediterranean region whose economy is based on the touristic sector (Costa del Sol). A cross-sectional, observational design was used to investigate the consumption of alcohol during pregnancy, based on a self-reporting questionnaire. A total of 451 women in the first, second or third trimesters of pregnancy were recruited. Consumption prevalences in each trimester were 40.7%, 25.5% and 17.1%. A higher educational level was associated with greater exposure to alcohol (risk ratio, 1.87 [1.30-2.69]). These results should alert the providers of obstetric care in touristic areas to the need for the adoption of adequate preventive measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
