The present study is a detailed evaluation of age at smoking initiation among university male students in Kuwait based on a random sample of 664 students selected from all students during 1993, The Acturial Life Table analysis revealed that almost one tenth of the students initiated cigarette smoking between ages 16 and 17 with the rate of initiation increasing rapidly thereafter and reaching 30% by age 20 and almost 50% by the time they celebrate their 24th birthday.

The most important environmental risk factor positively associated for smoking initiation was observed to be the history of smoking among siblings with a relative risk of 1.4. Compared to students of medicine and engineering, the students of other faculties revealed a higher risk in smoking initiation with an RR=1.77 for sciences and commerce and 1.61 for other faculties (arts, law, education and Islamic studies).

The analysis revealed a rising generation trend in cigarette smoking.

There is a need for reduction of this trend among young adults in Kuwait and throughout other countries in the region.
