title: Prevalence of smoking among Karachi population.
abstract: OBJECTIVE
  To determine the prevalence of smoking in Karachi population and compare it with previous studies to see if any change has occurred in this addiction.
  
  
  METHODS
  Cross sectional survey in 5 districts of Karachi, using a questionnaire.
  
  
  METHODS
  Apparently healthy subjects from 25 areas covering 5 districts of Karachi were interviewed regarding their smoking habits, ethnic origin, socioeconomic strata and the education level. Two modes of interview were adopted, one was a house to house and the other was interview at public places.
  
  
  RESULTS
  Previous studies showed a 21-32.3% prevalence of smoking which is almost similar to 32.7% seen in this study. In the present study highest frequency of smoking was seen in college going male students belonging to 21-25 years while in females majority were graduates belonging to 26-30 years age group. The age at which most cases acquired this habit was between 15-25 years and in majority it was introduced by friends. Although most knew that smoking was hazardous for health and many cases did make an attempt to quit but very few were able to get rid of this addiction.
  
  
  CONCLUSIONS
  Over the past few decades not much change has been seen in the frequency of smoking in our population. Stronger anti smoking campaigns using press and other media are required to improve public awareness.
