Which trimester has the highest reported alcohol use among pregnant women?

The first trimester is recognized for having the highest reported alcohol use among pregnant women based on various studies and surveys. During this period, many women may not yet be aware of their pregnancy, which can lead to unintentional alcohol consumption. Additionally, it is often when women might still engage in pre-pregnancy lifestyle habits without considering their fetal health. Awareness and understanding of the risks associated with alcohol consumption generally increase as the pregnancy progresses, particularly in the later stages when prenatal care is more regularly sought, and education about pregnancy risk factors becomes more prevalent.

Overall, the data highlights that the impulsivity and potential lack of awareness during this initial stage can contribute to higher alcohol use rates compared to later trimesters when the consequences of alcohol consumption are more widely known and understood.
