Background - There have been numerous studies on smoking habits among
young adults in developed countries. Similar data from developing coun
tries are scanty. Methods - A survey of medical students from one of t
he medical colleges in Pakistan assessed their smoking habits and atti
tudes towards smoking. In June 1993 a coded survey questionnaire was s
ent to each medical student at The Aga Khan Medical University in Kara
chi requesting data on their smoking habits, their attitudes towards s
moking in various areas of the hospital, and their views about passive
smoking and tobacco publicity. Results - Of 324 medical students, 89%
responded of whom 11% were current smokers. The incidence of smoking
was greater among male students than females (17% versus 4%). The aver
age age of initiation of smoking was 17 years and the major influence
was friends. There was an increased awareness of harmful effects of sm
oking among medical students. Almost all felt that passive smoking was
injurious to health. Conclusion - The prevalence of current smokers a
mong Asian medical students was found to be 11%. Females smoked less t
han their male counterparts. There has been an increased awareness of
the hazards of passive smoking among the medical students and most wer
e in favour of legislative actions to discourage tobacco advertising.
