BACKGROUND-AIM:
This study focuses on Romanian pregnant women and aims to access active and passive smoking among them as well as their correlations and socio-demographic factors influencing these behaviors during different periods of time before and after comprehensive ban of smoking in public places in Romania.

METHODS:
The study was carried out in Cluj-Napoca, a big town from North-West part of Romania, in September-November 2011 (T1) when limited information with regard to lifestyle related behaviors of pregnant women from Romania was available and was repeated in January-March 2016 (T2), just before the implementation of comprehensive ban of smoking in public places in Romania as well as in October-December 2019 (T3) in order to have an evaluation of the evolution during time. It included pregnant women who presented themselves for a medical check-up at general practitioners or the 2 public gynecology clinics from Cluj-Napoca, Romania. The sample consisted of 160 women at T1, 100 women at T2 and 100 women at T3

RESULTS:
At T1 12.5% of women smoked during pregnancy and 8.7% declared smoking in the last month. At T2 both smoking during pregnancy and current smoking increased to 20%, respectively 17%, while at T3 both behaviors decreased to 16% and 12% respectably, but were still a bit higher than at T1. Current smoking was higher among women from rural areas at T1 and among those with lower educational level at T2 and T3. With regard to exposure to passive smoking among smokers, around half were exposed in public places at least once in the last week both at T1 and T2, while at T3 it decreased to one quarter. Moreover, more than 40% were exposed to passive smoking at home at least once in the last week at T1 and T3, while at T2 the percentage was around 70% . Among non-smokers, more than one third were exposed to passive smoking in public places at least once in the last week at T1 and T2, but in 2019 only 7% declared such exposure. The percentage of exposure at home varied between 11%-14% (at T3 and T1) to 20% (at T2). Exposure to passive smoking in public places was higher also among women from rural areas at T1, while lower educational level and younger age was more frequent among those exposed to passive smoking in public places at T2. Exposure to passive smoking in the own house was higher among those with lower educational level at all waves and among participants with lower age of pregnancy at T2 and T3 as well as with lower age at T2.

CONCLUSIONS:
The results call for development, implementation and evaluation of educational programs and measures which stimulate and help healthy lifestyle promotion among pregnant women in Romania, proving at the same time that public health measurements such as comprehensive bans of smoking in public places had a clear impact on Romanian pregnant women.
