Relationship Between Maternal Alcohol Exposure During Pregnancy and ADHD in Their Elementary and Middle School Aged Offspring

Background and Objectives ： This study was designed to evaluate the relationship between maternal alcohol exposure and ADHD in their elementary and middle school aged off-spring in Pusan, Korea. Materials and Methods ： Students from two elementary schools and one middle school in Pusan were selected. Questionnaires were distributed to their mothers. Maternal alcohol exposure during pregnancy was investi-gated using a questionnaire including questions regarding their drinking behavior during pregnancy. The presence of ADHD in their offspring was measured using the Korean ver-sion of DuPaul ADHD Rating Scale (K-ARS). Results ： Questionnaires were distributed to 1,060 mothers, including 660 mothers of elementary school students and 400 mothers of middle school students. A total of 927 mothers completed the questionnaires, including 625 mothers of elementary school students and 302 mothers of middle school students. The overall response rate was 87.5%. The response rate in mothers of elementary school students and mothers of middle school students was 94.7% and 75.5%, respectively. The number of offspring whose total score of K-ARS was 19 or more was significantly larger in mothers who drank during pregnancy (p=0.005), particularly, in elementary school students (p=0.015), compared to that in mothers who did not drink during preganacy. Conclusion : Our results suggest that maternal alcohol exposure during pregnancy is related to ADHD in their offspring. Therefore, the risk of maternal alcohol exposure during pregnancy needs to be emphasized.
