Impact of educational intervention on knowledge and awareness of TB among secondary school students in The Gambia
Abstract
Objectives: Health education and awareness campaigns about tuberculosis (TB) can empower adolescents on different aspects of the disease and its management, resulting in early and appropriate care seeking behavior through their advocacy in the community. We assessed the impact of educational intervention on knowledge and awareness about TB among adolescents in the greater Banjul area of The Gambia where approximately 70% of national TB cases are notified.
Materials and Methods: A school-based, interventional analytical study, and interactive educational workshop was conducted among grade 12 students of the Methodist Academy Secondary School in Bakau, Banjul The Gambia. The workshop activities included illustrative demonstrations using posters, flipcharts, infographics, and games to convey TB messages in six domains: (1) Basic knowledge; (2) symptoms; (3) risk factors (4) modes of transmission; (5) treatment; and (6) care and support. Structured questionnaires were used to assess changes in the student’s knowledge and awareness about TB in the six domains before and after the workshop. Data were analyzed using proportional percentages, mean (95% CI) and differences standard error (SE) and student paired t-test.
Results: Ninety-six students participated in the workshop out of which 92 (96%) students completed both pre- and post-test questionnaires. Sixty-eight percent of the students were females and 58% were from the science stream of the grade 12 students who participated in our workshop. The mean difference and SE between the pre- and post-workshop test scores in the six domains were: basic knowledge: +1.4 (0.2; P < 0.0001); symptoms: +1.5 (0.2; P < 0.0001); risk factors: +3.1 (0.3; P < 0.0001); modes of transmission: +1.2 (0.2; P < 0.0001); treatment: +0.8 (0.1; P < 0.0001); and care and support of TB: +0.5 (0.1; P = 0.0001).
Conclusion: This school-based educational interactive workshop significantly improved the knowledge and awareness of the students especially in understanding the causative agent and risk factors of TB disease. We recommend exposure of students to TB educational activities as part of the school curriculum. The knowledge acquired in this workshop is likely to have impact on the wider community and should be assessed in future follow-up studies to determine if it impacts positively on views held within the wider community.
