This study looked at national data to see how many mothers in the United States reported smoking cigarettes at any time during their pregnancy in the year 2020. The research focused on the percentage of births where the mother said she had smoked. The study did not report the actual number or percentage of mothers who smoked, nor did it compare them to mothers who did not smoke. The study was observational, meaning it simply described what was reported in the data for that year. It did not follow mothers over time or examine the health of their babies. Because the results were not reported, we cannot draw any conclusions from this specific study about smoking rates. The main reason to be careful is that this summary only tells us a study was done on this topic for 2020, but it does not share what was found. Readers should know that smoking during pregnancy is a known health concern, but this particular analysis does not provide new numbers or trends. Realistically, this serves as a reminder that researchers track this information, but we would need the actual results to understand the situation.

This observational study analyzed data from mothers who gave birth in the United States in 2020. The exposure of interest was self-reported smoking cigarettes at any time during pregnancy. The primary outcome was the percentage of births to mothers with this reported exposure.
The main result for the percentage of births to mothers who reported smoking during pregnancy was not reported in the provided data. No effect sizes, absolute numbers, p-values, or confidence intervals were available. The direction of any association or comparison was also not reported.
No safety, tolerability, or adverse event data related to the smoking exposure were reported. Key limitations include the reliance on self-reported data for smoking status and the absence of reported comparator data or specific prevalence rates. The study's funding sources and potential conflicts of interest were not reported.
For clinical practice, this report offers a descriptive look at maternal smoking exposure in a recent U.S. birth cohort. However, the lack of reported prevalence figures limits its direct utility. Clinicians should continue to counsel patients against smoking during pregnancy based on the well-established body of evidence linking it to adverse outcomes.
