Objectives: To evaluate the relationship between the frequency of self-declared status regarding smoking in a group of pregnant women from Mures county, Romania and the high levels of Salivary Cotinine (SC) like biomarkers.
Material and methods: It was conducted a retrospective study among 230 pregnant women presented for prenatal care at 50 General Practitioners cabinets in Mures county, Romania, in 2015. Data were collected with a validated questionnaire which included age, level of education, socioeconomic status and ethnicity, also the self-reported smoking status. The Salivary Cotinine level was evaluated using NicAlert Saliva test kits.
Results: Using salivary test we identified a high prevalence of involuntary exposure to cigarette smoke among both non-smokers and those who quit smoking before pregnancy. Also we registered pregnant women that although declared smoking cessation before pregnancy their salivary Cotinine levels were high, almost like to an active smoker, probably because of second-hand exposure or because they didn’t say the truth about their habit.
Conclusions: We underline the importance of implementing more efficient community interventions among this vulnerable group in order to reduce the frequency of smoking and sustain quitting.
