| Summary: | Background
Tobacco smoking is a leading cause of preventable
deaths globally. Although tobacco-induced burden has started decreasing in
developed countries, it is continuously increasing in developing countries with
young populations being mostly affected. This study aimed to determine the
prevalence of active and passive smoking among youths in Cameroon.
Methods
This was a cross-sectional study carried-out from May-July 2017 at the University of Yaoundé I, Cameroon. We included any student registered at the University, found at one of the campuses when the investigators visited, and volunteering to participate. Smoking status was classified as never, former (last smoked more than 12 month ago) or current (smoked regularly in the last 12 months). Passive smoking was defined as a regular exposure to tobacco smoke since the last twelve months.
Results
Overall, 949 (54% males) were included in this
study, with a median age of 23 years (interquartile range (IQR) 21-26). The prevalence
of former, current and passive smoking was 3.4% (95% confidence interval (CI):
2.3-4.6), 0.8% (95%CI: 0.2-1.4), and 27.7% (95%CI: 24.9-30.6), respectively. Exposure
to other people's smoke ranged from 1 to 50 hours per week, with a median of 1
hour/week (IQR 1-2). Those who smoked were more likely to be males (odds ratio
(OR) 2.05, 95%CI: 1.03-4.08; p=0.037) and/or hazardous alcohol drinkers (OR 4.93, 95%CI: 2.55-9.52; p< 0.001).
Similarly, males (OR 1.57, 95%CI: 1.18-2.11; p=0.002) and/or hazardous alcohol drinkers
(OR 2.10, 95%CI: 1.55-2.86; p< 0.001) were more at risk of passive
smoking.
Conclusions
Although the prevalence of active smoking seemed low in this
population, almost one-third of students were passive smokers, reflecting a
high burden of tobacco smoking in the general population. Therefore,
regulations towards tobacco consumption should be reinforced in our country.
Specifically, special laws banning and severely punishing smoking in public places
should be voted and adopted.
