“…The only Spanish study that examined the evolution of consumption among expectant mothers described a declining trend throughout the territory (Martínez‐Frías et al., ). Other European countries (Kesmodel et al., ; Strandberg‐Larsen et al., ), together with the United States (Cil, ) and Australia (Callinan and Ferris, ; Cameron et al., ), have also experienced similar rapid declines.…”

Background Even small amounts of alcohol consumed during pregnancy can have adverse effects on the embryo and the fetus. We estimated how alcohol intake among pregnant women in Spain changed between 1980 and 2014, and identified factors associated with alcohol use. Methods Data came from the Spanish Collaborative Study of Congenital Malformations (ECEMC). The sample includes ECEMC′s control mothers, 40,268 pregnant women from all regions of Spain. We classified alcohol consumption during pregnancy into 3 categories: no consumption; sporadic consumption of small amounts of alcohol; and regular consumption, or sporadic but in large quantities including drunkenness. Independent variables included sociodemographic factors, planned/unplanned pregnancy, maternal chronic diseases, gestational diabetes, and tobacco and illegal drug use during pregnancy. Trend analyses were performed using data from 1980 to 2014. The multinomial logistic regression models designed to identify associated factors differentiated between 2 periods: 1994 to 2004 and 2005 to 2014. Results Prevalence of alcohol consumption declined from 29.6% (95% CI: 27.1 to 32.2) in 1980 to 5.4% (95% CI: 3.7 to 7.6) in 2014, mostly due to the reduction in regular intake. This decline was especially acute between 1980 and 1994. Sporadic and regular consumption increased among women working outside the home, born outside Spain, those whose pregnancy was unplanned, and those reporting using tobacco or other drugs. Comparing 1994 to 2004 versus 2005 to 2014, a stronger association was observed between regular alcohol consumption and tobacco consumption in the latter period (interaction p = 0.003). Conclusions Alcohol consumption among expectant mothers has declined substantially in the last 35 years. However, it is worth highlighting the significant and substantial associations between alcohol use and consumption of tobacco, which have become stronger in the most recent years.

“…About 10% of the world female population consumes alcohol during pregnancy, a proportion that reaches 25% among European women (Popova et al., ). However, trends in several industrialized countries reveal a significant reduction in consumption (Callinan and Ferris, ; Kesmodel et al., ; Waterman et al., ).…”

“…Healthcare professionals did not inform the pregnant women sufficiently, as documented in this and other studies (Kesmodel and Kesmodel, ; Kesmodel et al., ). It is also important to note that alcohol consumption among pregnant women is decreasing in Denmark (Danish Health Authority, ; Kesmodel et al., ). There has been a constant reduction in the proportion of pregnant women drinking alcohol from approximately 1999 until 2013 (Kesmodel et al., ).…”

Background: In 1997, The Danish Health Authority recommended that "it is safest not to drink alcohol when you are pregnant," and in 1999 expanded recommendations. There are only a few studies evaluating the possible change of average alcohol consumption following changes in national recommendations, and no studies have been found comparing the changes in pregnant women's attitudes toward alcohol consumption during pregnancy. We aimed to evaluate the changes in drinking pattern, and knowledge about and attitudes toward alcohol consumption during pregnancy before and after the change of national recommendations.Methods: This is a cross-sectional interview study with a representative sample of 1,418 woman attending antenatal care at the beginning of their second trimester in Aarhus, Denmark, in the year 2000, and a comparable sample of 439 pregnant women from 1998 in Aarhus. Participants were interviewed about their average alcohol consumption, binge drinking, and attitudes toward and knowledge about alcohol consumption during pregnancy. Data collection procedures and questions were identical for both samples.Results: There were no differences between the 2 samples in terms of average alcohol consumption before (p = 0.19) and during (p = 0.45) pregnancy, and binge drinking in early pregnancy (p = 0.47). Attitudes toward and knowledge about alcohol in pregnancy did not change either (p > 0.5). Women's knowledge about guidelines was less precise in 2000 (p < 0.001). Worse knowledge was associated with younger age considering both samples (OR = 2.63, 95% CI: 1.63 to 4.26). Most pregnant women reported that they had not been informed or advised about alcohol consumption during pregnancy, but they would like to be advised by their healthcare professionals.Conclusions: After the changes in the national guidelines about alcohol consumption during pregnancy, there were no changes in behavior, attitudes, and knowledge of pregnant women. This would indicate that healthcare specialists should be encouraged to initiate a conversation about alcohol consumption during the first antenatal visit.

Association of light-to-moderate alcohol drinking in pregnancy with preterm birth and birth weight: elucidating bias by pooling data from nine European cohorts

Women who drink light-to-moderately during pregnancy have been observed to have lower risk of unfavourable pregnancy outcomes than abstainers. This has been suggested to be a result of bias. In a pooled sample, including 193 747 live-born singletons from nine European cohorts, we examined the associations between light-to-moderate drinking and preterm birth, birth weight, and small-for-gestational age in term born children (term SGA). To address potential sources of bias, we compared the associations from the total sample with a sub-sample restricted to first-time pregnant women who conceived within six months of trying, and examined whether the associations varied across calendar time. In the total sample, drinking up to around six drinks per week as compared to abstaining was associated with lower risk of preterm birth, whereas no significant associations were found for birth weight or term SGA. Drinking six or more drinks per week was associated with lower birth weight and higher risk of term SGA, but no increased risk of preterm birth. The analyses restricted to women without reproductive experience revealed similar results. Before 2000 approximately half of pregnant women drank alcohol. This decreased to 39% in 2000-2004, and 14% in 2005-2011. Before 2000, every additional drink was associated with reduced mean birth weight, whereas in 2005-2011, the mean birth weight increased with increasing intake. The period-specific associations between low-to-moderate drinking and birth weight, which also were observed for term SGA, are indicative of bias. It is impossible to distinguish if the bias is attributable to unmeasured confounding, which change over time or cohort heterogeneity.

Time trends in alcohol intake in early pregnancy and official recommendations in Denmark, 1998–2013

Abstract: The decline in the proportion of pregnant women consuming alcohol occurred independently of official recommendations. Increasing national and international awareness may partly explain the changes.
