The aim of the study was to prove that there is a strong need among the smoking population for the antismoking telephone helpline, and to describe the structure and dynamics of calls to the Call-center. Basic data on socio-demographic characteristics, smoking habits, and reasons for calling the Center were collected during telephone conversations with smokers. The data were entered into previously prepared tables. Statistical analysis included 7,452 telephone calls; most calls were received from persons aged 26-45 years (34%), followed by 19-24 (24%) and 45-60 (19%) age groups. There was no statistically significant difference in the number of calls between men and women (54% vs. 46%, respectively). Most callers consumed on average 20 cigarettes per day. The most frequent reason for calling was to get on how to stop smoking, whereas seeking information on professional literature was the least frequent reason for calling among our respondents. Four-fifths of persons making a call to the Center started smoking when they were between 16 and 20 years of age. We can conclude that there was a need for this type of intervention due to its accessibility and potentially wide coverage of interested users.
