title: Influence of Family Smoking Habits and Passive Smoking on Smoking Status Among Belgrade University Students.
abstract: BACKGROUND
  There are many factors that affect smoking behavior.
  
  
  OBJECTIVE
  The aim of our study was to identify the most important risk factors related to smoking in the sample population of students at the University of Belgrade with a special emphasize on the family role.
  
  
  METHODS
  The cross-sectional study was conducted in a population of 2,000 students of the Belgrade University. Four faculties (Medicine, Geography, Economics, and Electrical Engineering) from which the students participating in this research were chosen by the method of random choice, conducted in the period April-June 2010.
  
  
  RESULTS
  Independent risk factors for smoking in students, assessed by multivariate logistic regression analysis, included: repeating a year (odds ratio (OR) = 1.67, p < .001), the number of hours spent in the rooms where others smoke (OR = 2.86, p < .001), brother smoker (OR = 1.88, p < .001), sister smoker (OR = 2.33, p < .001), knowledge about the association between smoking and lung cancer (OR = 0.31, p < .001), and depression (OR = 1.02, p = .013).
  
  
  CONCLUSIONS
  Bearing in mind the influence of siblings, prevention, and intervention efforts should be focused more on family members than on the broader social environment. The results also indicate the need to develop a conscience on a healthy life style and to educate people to enhance and improve their health control.
