The question of drinking alcohol and child development can raise strong emotion. Does drinking alcohol during pregnancy have any impact on child development? What about smoking during pregnancy? These are very important questions.
I. The Study
The study involved 1,006 children. It began during the prenatal period. That is, from between 22 and 25 weeks of pregnancy. What would be the effects of drinking and/or smoking during pregnancy? Specifically, on children’s motor and cognitive skills?
Negrão and colleagues evaluated the infants at birth. They then reevaluated them during their second year of life. To do so, they used sub-scales of the Bayley Scales of Infant and Toddler Development (Bayley-III). Those measured gross motor, fine motor, and cognitive skills.
The researchers placed mothers into one of the following categories. It was based on their behavior during pregnancy.
- Neither drinking nor smoking (NC).
- Drinking, or alcohol consumption, but not smoking (AC).
- Smoking tobacco (tobacco “consumption”) but not drinking (TC).
- Doing both (ACTC).
Researchers also analyzed separately alcohol (AC) and tobacco use (TC). Again, it was in comparison to the NC group. They found that neither was associated with either delayed motor or cognitive skills.
