[Results of a controlled randomized study on prevention of smoking habit in adolescents].

We describe the results of a randomized controlled study on the efficacy of a smoking prevention program based on behavioral methods (Waterloo Smoking Prevention Program 1, adapted). 792 children of 12-13 years of age from the Health District of Rozzano (MI) were the study base. The program was delivered directly by voluntary teachers during school classes.

[Protocol and feasibility of a randomized controlled study on preventing the smoking habit in adolescents].

As no similar study has been conducted in Italy, the Local Health District (USL) of Rozzano (Milano), decided to carry on a randomized controlled trial on the efficacy of a Smoking Prevention Program. In this article we describe study protocol and give data related to program steps already carried out. A team of four MDs involved in school health and a Health Research consultant were in charge for the study.
