title: Khat chewing habit among school students of Jazan region, Saudi Arabia.
abstract: BACKGROUND
  The use of Khat leaves (Catha edulis) in Jazan, southwest of KSA, is prevalent among all segments of the population.
  
  
  OBJECTIVE
  This study was conducted to assess the prevalence and predictors of Khat chewing among intermediate and secondary school students of Jazan region.
  
  
  METHODS
  A cross-sectional survey was conducted in late 2011 in Jazan region. A random sample of 3923 students was selected from 72 intermediate and upper secondary schools representing the different educational sectors of the region. A structured self-administered questionnaire was used for data collection. Descriptive statistics, a chi-squared test and logistic regression were performed to examine the prevalence, associations and predictors of Khat chewing.
  
  
  RESULTS
  The overall Khat chewing prevalence among students was 20.5% (95% C.I.: 19.27-21.79). The prevalence was significantly higher among males, at 33.1% (95% CI: 31.16-35.08), than among females 4.3% (95% C.I.: 3.39-5.31) ( P <0.001). Univariate analysis revealed that gender, age, academic performance, friends' smoking and Khat chewing, and students' smoking status were associated with a significantly high risk of Khat chewing ( P <0.001 for all). The multivariate logistic regression analysis suggested that the most important independent predictors of Khat chewing among the students in our sample were students' smoking status (OR = 13.02, P <0.001), friends' use of Khat (OR = 5.65, P <0.001), gender (OR = 4.62, P <0.001), and friend's use of tobacco (OR = 1.43, P <0.001).
  
  
  CONCLUSIONS
  A significant percentage of students chew Khat. The abuse of Khat is significantly associated with gender, peer influence, and cigarette smoking. Intervention programs are needed to create awareness among school students and to reduce the prevalence of the habit and its unfavorable consequences.
