TRIAL DESCRIPTION
Public title Effectiveness of Health Education Methods on Adolescents’ Susceptibility to Tobacco Uptake – Cluster-Randomised Control Trial
Official scientific title Susceptibility of Adolescents to Tobacco Use and the Relative Effectiveness of Health Education Methods – A Cluster-Randomized Control Trial
Brief summary describing the background and objectives of the trial Background: Tobacco use is associated with high mortality and morbidity; Killing more than half of its users. It is also worrisome that over 80% of the smokers reside in Low and Middle-Income Countries (LMICs). Tobacco use has attained the level of an epidemic in many LMICs. The epidemic is sustained by the addition of many youths and adolescents to the population of tobacco users, with more than 2,800 adolescents initiated daily. Tobacco use causes numerous oral and general health problems. The nicotine content is highly addictive and adversely affect brain development, which is still ongoing in adolescence. Despite all the tobacco control efforts, the prevalence of tobacco use continues to increase in Africa. This is mainly due to focus on getting smokers to quit, and neglect of preventing tobacco uptake by adolescents. Tobacco cessation programs have thus yielded little or no success because of the addictive effect of tobacco. It is imperative to shift attention to preventing non-smokers, especially adolescents, who are susceptible to tobacco smoking, from taking up the habit. Although different avenues are available to prevent adolescents from initiating tobacco uptake, the school has given promising outcomes. Different school-based tobacco prevention interventions have been evaluated with successes in preventing adolescents from initiating tobacco uptake in developed countries. It is, however, unknown, which of these methods is most appropriate for low resource settings like Nigeria. A country like Nigeria, lacking in both human (health professionals) and financial resources, needs to adopt an intervention method that is not only effective but also sustainable. The objective of the study: To compare the effectiveness of dentist-led lecture and self-directed learning methods of health education on school-going adolescents’ susceptibility to tobacco use in Ibadan, Oyo State, Nigeria.

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group Self directed method of learning Two sessions 45 minutes All the selected students in this group will be given at least two customized notebooks. Information on the constituents, oral and general health effects of tobacco use, as well as messages depicting benefits of quitting tobacco use will be presented graphically and in writing on the front and back cover pages of the notebooks. Posters with similar information as the notebooks will be pasted on the walls of the classrooms of the selected students. The posters and notebooks will be distributed about the same time that the researcher is conducting the first round of training sessions to those in group 1. The researcher will be responsible for the distribution of the notebooks and posters, but the researcher will not initiate any discussions with the students. The selected students per school will be assembled in the hall for about 30 minutes, like the dentist-led group. The reason is to guarantee a protected time for the students during which they could study/focus on the educational materials. The protected time will also ensure that the main difference between the two groups will be the lecture by the researcher. The participants will not be prevented from asking one another questions, but no tobacco-related questions will be answered by the researcher. Follow-up session of the intervention: Like in group 1, after the first session, there will be one follow-up session, which will also take place after two weeks. During the follow-up visit, the researcher will give the study participants another set of customized notebooks, and replace any poster that may be damaged or missing from the classroom walls. 360
Control Group Dentistled health education lectures One session 45 minutes Participants in this intervention group will receive health education lectures conducted by a trained dentist (researcher). The participants will receive one session of lectures. The period for the training sessions will be discussed with the school principal, such that periods, where all the students will be free of classwork, will be chosen. The training session will last for about 45 minutes and will involve the delivery of the lecture (35 minutes) and questions and answers (10 minutes). The lecture will cover the following areas as contained in the standardized manual: constituents and types of tobacco products (smoked and smokeless), the adverse oral and general health effects of tobacco use, and clarifications on the common erroneous perceptions about the use of tobacco among adolescents. 360 Active-Treatment of Control Group
Control Group Control Nil Nil In the control group, baseline data will be collected. This will be followed by health education on tooth cleaning and other personal hygiene practices that will be given to the study participants. The session will follow the same approach as the intervention groups, with the only difference being the content (tobacco-related messages) and the absence of tobacco-customized notebooks and posters. After the final data collection, a session of tobacco-related health education will be given to the study participants, along with one customized notebook with tobacco-related information. Follow-up sessions of the health talk: There will be no follow-up training visit for this group. Although, they be followed up till the end of the study, and two further surveys (immediate post-intervention and final surveys) would be conducted as with the intervention groups. 360 Placebo
