Teachers have an important responsibility in tobacco control given that they are highly respected in their communities as they influence the evolution for each aspect of life [8,9]. It has been recognised that teachers are important role models for students, Bicalutamide Kalumid conveyors of tobacco prevention curricula and key opinion leaders for school tobacco control policies [9,10]. In addition, teachers have daily interaction with students and thus represent an influential group in tobacco smoking control. However, this potential can be limited if teachers use tobacco especially in the presence of students in school premises [10]. The results of a study carried out in Nairobi, Kenya to determine the prevalence

and risk factors of smoking among secondary school students indicated that, smoking among students started very early in their life due to the smoking habits of their parents at home and teachers at school

[11]. Similar results were found in the study conducted to assess the influence of smoking and tombak (local smokeless tobacco) dipping by parents, teachers and friends on cigarette smoking and tombak dipping by school going Sudanese adolescents [12]. Despite the important role of teachers on tobacco smoking control, few studies have been conducted to investigate tobacco smoking behaviours of school teachers. As far as the authors of this study could ascertain, no study on

tobacco smoking has been conducted among teachers in Botswana. The aim of this study was, therefore, to investigate and report on the prevalence of tobacco smoking among teachers in Botswana. Methods As part of a larger descriptive cross sectional study of occupational health issues, 3 100 school teachers in Botswana were surveyed. The study was approved by the University of Newcastle Human Research Ethics Committee and Botswana Ministry of Education and Skills Development. From seven education regions, 107 primary and 57secondary schools were randomly selected. All school teachers in those schools were invited to take part Brefeldin_A in the study. Permission to conduct the research in the selected schools was sought from school heads. Informed consent of teachers was implied by completing and returning the questionnaire. Data was collected from August to December 2012 by means of an anonymous, self-reporting questionnaire. Tobacco smoking variables were constructed to estimate cigarette smoking prevalence, and proportions of ex-smokers and those who have never smoked. Data was also collected on the number of cigarettes smoked daily and number of years since quitting to smoke. SPSS 20.0 was used to analyse the collected data. Pearson’s chi-square tests were used to determine statistical associations with smoking. Results An overall response rate of 56.3% was obtained in this study.
