Prevalence of cigarette smoking and khat chewing among Aden University medical students and their relationship to BP and body mass index

Abstract EN

To evaluate the smoking and khat chewing habits in male Aden University medical students and correlate them with blood pressure (BP), body mass index (BMI), and year of training, we randomly selected 100 students of different levels of training and measured their BP, height, and weight, and evaluated their cigarette smoking and khat chewing habits.

The mean age of the whole group was 31.8 years.

The mean BMI was 23.24 with a range from 22.6 in the in first year medical students to 24.7 (4.4) in 5 th year medical students (P= 0.127).

The mean SBP, DBP, and MBP were 120.35, 70.47 and 87.1 mmHg, respectively, and did not change over the years of training.

Prevalence of smoking increased from 20% to 40% and khat chewing from 35% to 90% over the 5 years of training (P= 0.0003).

There was a tendency for positive correlation between age and weight, BMI and frequency of khat chewing, and BMI and MBP.

We found high prevalence of smoking and khat chewing among the medical students at Aden University and their prevalence increases with student seniority with no significant changes in BMI, SBP, DBP or MBP.

There was a weak positive correlation between BMI with SBP, MBP and frequency of Khat chewing.
