Introduction:
Prenatal exposure to tobacco is associated with a wide range of adverse health outcomes In children ¹. At the Paediatric Environmental Health Specialty Unit (PEHSU) in Catalonia (Spain), pregnant women and their partners receive a paediatric environmental health visit (“Green Page”) in which the environmental nurse screens for several environmental risk factors, including smoking. Smokers (both pregnant women and their partners) are invited to participate in a cessation programme based on a motivational interview by the environmental nurse and access to free smoking-cessation medication subsidized by the local hospital ².

Material and Methods:
Longitudinal study. Total sample; N=154 (n=77 pregnant women and n=77 partners). Data were collected using the “Green Page”. Variables included smoking status, joint intervention of pregnant women and their partners or separate intervention, pharmacological treatment for smoking cessation, and follow-up time of the intervention. A descriptive analysis of education level, age, economic level, and country of origin was performed. A bivariate analysis was conducted using Pearson's chi-squared test, and statistical differences were established at a p-value of <0.05, with values presented as odds ratios.

Results:
Mean age of pregnant women = 31.23 (SD 5.5). About pregnant, 48.8% dropped out of the intervention, 32.5% decreased their consumption and 18.60% quit smoking. In the case of partners, 60.37% dropped out of the intervention, 15.09% decreased their consumption and 24.52% quit smoking. The results showed a positive effect if the pregnant’s partner did not smoke: in these cases, none abandoned the intervention. If both members of the couple smoked and underwent the intervention together, both quit smoking (100%).

Conclusions:
Health education during pregnancy should include the partner. Offering the intervention together and free treatment to both increases the chances for the pregnant women and their partners to quit smoking.
