3. PROBLEM STATEMENT<br />

There is sufficient evidence that tobacco use, in its different forms, is a risk factor for chronic<br />

illnesses such as cardiovascular, respiratory and periodontal diseases; and for cancers of oral<br />

cavity, upper respiratory tract, and other parts of the body. Interventions against tobacco use<br />

need to be instituted in order to reduce the number of smokers in Tanzania and therefore the<br />

risk of chronic diseases. To justify for any intervention on tobacco use, one needs to<br />

determine the magnitude of tobacco use in a given society. In addition, factors that facilitate<br />

people to use tobacco and those that may deter them from tobacco use need to be identified.<br />

At the time of planning the current study, there was insufficient information on use of<br />

different forms of tobacco among secondary school students in Dar es Salaam. The extent on<br />

the level of knowledge of the health effects of tobacco use was also lacking. Similarly, factors<br />

that may influence secondary school students to start using tobacco had not been adequately<br />

investigated in Tanzania. Therefore the study was designed based on the summary of the<br />

possible interactions shown in conceptual framework shown in figure 1.
