Introduction:

Smoking is one of the main preventable Public Health problems in the world. In Tucumán there is no information about specific groups such as pregnant women. The objective of this study was to estimate the prevalence of smoking in pregnant women and its determining factors in Tucumán.

Methods:

The target population were pregnant women who attended the selected institutions. The “lme4” library of the R software was used. Bivariate analysis was performed using the Chi-square or Fisher test as appropriate. Logistic regression was used to determine the variables with association.

Results:

The lifetime prevalence of smoking was 41.5%. 25.3% of women were smokers when they found out they were pregnant, 86.2% of them quit smoking at some point during their pregnancy. The educational level of the pregnant woman and her partner, the household rules and not being aware of the damage produced by smoking were some of the variables associated with being smokers.

Conclusions:

In this study, smoking prevalence in pregnant women was reported to be 25%. It also presents determining factors in specific population groups about which there is scarce information in our area.
