title: Design, baseline results of Irbid longitudinal, school-based smoking study.
abstract: OBJECTIVE
  To compare patterns of water pipe and cigarette smoking in an eastern Mediterranean country.
  
  
  METHODS
  In 2008, 1781 out of 1877 seventh graders enrolled in 19 randomly selected schools in Irbid, Jordan, were surveyed.
  
  
  RESULTS
  Experimentation with and  current water pipe smoking were more prevalent than cigarette smoking (boys: 38.7% vs 26.8%; 20.2% vs 9.0%, girls: 21.2% vs 9.5%; and 7.5% vs 2.3%, P<0.05 for all). Parent- and peer-smoking correlated more strongly with water pipe than with cigarette smoking.
  
  
  CONCLUSIONS
  Water-pipe  smoking is more prevalent than cigarette smoking at this early age.
