May 17, 2021 updated by: Divine Darlington Logo, Ghana Health Services

Development and Assessment of a Teacher-led Intervention in Preventing Tobacco Use Among Junior High Students in the Upper East Region of Ghana: A Cluster Randomized Controlled Trial

The main purpose of this experimental study is to compare the existing health education program for School Health and Education Program (SHEP) in the Junior High Schools with a new health education model (Smart-Kids') for the prevention of smoking initiation and to improve the quit rate among students in Upper East Region of Ghana. The intervention will be based on the Theory of Triadic Influences (TTI) which involves the cultural environment in which adolescents mature, their immediate social situation, and intrapersonal differences. These three factors impact through different mediating variables, such as attitudes, normative beliefs, and self-efficacy, which eventually affect smoking intentions and smoking behavior as the outcome measures. The study design is a cluster randomized control trial. After baseline assessment, the investigators will randomize schools to receive the new health education for three months whiles the comparator (control group) will continue with the usual health education. The investigators will conduct a post-intervention assessment using the same questionnaire with unique identity codes linking each participant to their baseline assessments immediately at the end of the intervention. Final assessment will be done approximately three months after the intervention. The investigators will assess and compare the effectiveness of the new health model to the normal health promotion programs (SHEP).

The investigators hypothesized that there will be no significant differences observed between the new teacher-led health education program (the Smart-Kids Program) and the existing SHEP coordinator-led in preventing smoking uptake among the youth.

Alternatively, the new teacher-led health education program would facilitate the effects of the program on outcomes. on four key primary endpoints as follows:

  • H1: The intervention study will result in a 30% reduction in smoking uptake
  • H2: The intervention study will result in a 10% reduction in smokers
  • H3. The intervention will increase knowledge of the harmful effects of tobacco use by 50%
  • H4. The intervention will increase the willingness to quit smoking by 10% among smokers

Study Overview

Detailed Description

Protecting adolescents against smoking initiation is a critical strategy for public health. It is a crucial strategy because it lessens tobacco-related disease burden on public health and importantly protects adolescents from becoming a smoker. Globally, almost 25 million and 13 million of the youth aged 13 to 15 years old currently smoke cigarettes and smokeless tobacco respectively.

Cigarette smoking during childhood and adolescence causes significant health problems, including respiratory illnesses, decreased physical fitness, and potential effects on lung growth and function. Of concern, every day about 80,000 to 100,000 children and adolescents initiate smoking, most of them in developing countries. Furthermore, among 1000 youth who smoke today, close to 500 will ultimately die of tobacco-related diseases.

In line with the global trends, Ghanaian youth smoking behavior is not too different from that of developed countries however, Ghana is considered to be at the beginning of the tobacco epidemic. Ghana having seen continuous reductions in tobacco use in the four rounds of the Global Youth Tobacco Survey (GYTS) conducted, the country still has close to one in ten youth continue to use a tobacco product. It is also, worth noting that, in addition to cigarette use, the youth are now into using other forms of tobacco products such as shisha, electronic cigarettes, and smokeless tobacco with higher usage among girls.

Significance of the study Prevention of tobacco use among the youth in a school setting is considered the most feasible and appropriate strategy for reducing tobacco consumption. The strategy, therefore, is intended to influence a large number of the youth not to start or/and assist to quit tobacco use. The intervention will prevent tobacco use, and provide the knowledge before transitioning to middle age, where they may be confronted with risky behaviors, such as tobacco use.

The intervention is primarily intended to lead to a reduction in smoking uptake and improve quit rate among the youth, and also increase knowledge about the harmful effects of tobacco use. The program is designed to effect positive behavior, self-efficacy, attitudinal change, and refrain from the use of harmful substances such as tobacco. In all these, the effects of the intervention may translate into a reduction in public health and medical costs associated with tobacco-related diseases.

Objective:

The primary objective of the study is to design, test, and implement a novel strategy for smoking prevention among youth in the Upper East Region Specifically;

  1. Evaluate the existing SHEP program on smoking prevention
  2. Identify risk factors for smoking
  3. Based on the above, design a novel strategy (Teacher-led) for prevention of smoking uptake and improved quit rate
  4. Compare smoking rate within the intervention group and the control group
  5. Make recommendations for policy action

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: The intervention Arm
This arm will receive the novel intervention package for a period of three months to prevent smoking initiation and increase quit rate. The intervention will consist of 4 lessons which will be taught for about one hour each day. This will be segmented into two broad areas as knowledge and skill development. Under the knowledge-based program, participants will be taught, the global challenge of tobacco and tobacco products, correcting the erroneous impression about tobacco, the media and advertisement, and the harmful effects of smoking. The skill development program teaches about refusal skills (self-esteem, interpersonal relationship skills, and problem-solving skills). The participants will understand the tobacco advertising and marketing strategies; peer influence, and skills for resisting influences to smoke.
The intervention is designed for all students, including never-smokers and students at high risk for smoking. Therefore, some contents are intended to influence those high-risk youth within the larger student audience by targeting the stages of the smoking acquisition process including, preparation, initiation, experimentation, regular use, and addiction (Mayhew et al., 2000). The intervention is also focused on addressing risk factors for smoking initiation and continue use (Hansen et al., 2015; So & Yeo, 2015). These risk factors are, therefore, grouped into four major groups namely; personal factors, behavioral factors, environmental factors and sociodemographic factors
Active Comparator: The Control Arm
The control arm will not receive novel intervention program but will continue with the usual School Health and Education program (SHEP) however, at the end of the intervention, all the materials will be sent to the control arm to also benefit from the lessons.
The SHEP is the usual health and education program been done in all schools, and also has tobacco control component. This is will be used as the control for the intervention.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Behavioral Change
Time Frame: Immediately after intervention
Behavior change from baseline at 3 months. The Glover-Nilsson Smoking Behavioral Questionnaire (GN-SBQ) will be used to assess smoking behavioral change. The GN-SBQ is an 11-item, to evaluate the effect of behaviors associated with smoking. A higher score indicates favorable behavioral change towards tobacco use whiles a lower score shows unfavorable behavior change.
