Influence of educational level on the prevalence of risk behaviors during the perinatal period.

The objective of this work was to assess changes during pregnancy and after childbirth in diet, consumption of tobacco, electronic cigarettes, cannabis, alcohol use and exposure to environmental tobacco smoke depending on the mother's educational level.A cross-sectional study was carried out whose target population was 18,822 Galician women aged 18-49 who gave birth between September 2015 and August 2016, and their 19,204 live-born children. A descriptive analysis was performed, and the prevalence of different behaviors was estimated at three time points - pre-pregnancy, pregnancy and after childbirth - depending on the mother's educational level. Percentages of change were calculated.Information was obtained from 6,436 women. Regardless of the educational level, during pregnancy there was an improvement in the different lifestyles. In the first months after childbirth, lifestyles worsened, except for exposure to environmental tobacco smoke and the use of electronic cigarettes. Most of the risk behaviors showed a gradient depending on the educational level; thus, the lower the educational level, the higher the prevalence of risk behaviors.In general, during pregnancy all women adopted healthier lifestyles that they abandoned in the months following childbirth. Women with a lower level of education showed a higher prevalence of risk behaviors, both in the period prior to pregnancy, as well as during pregnancy and after childbirth.
