Background
Cardiovascular diseases (CVD) are the number one public health challenge of the 21st century. Globally, the disease causes more deaths than any other cause. Unfortunately, many people are not aware of CVDs and its risk factors and because of this the disease burden keeps on rising. Objective of this study was to develop, implement and evaluate the effects of a health education program to improve CVD knowledge, motivation, and behavioral skills among secondary school students in Ghana.
Methods
A parallel single-blind cluster randomized controlled trial was carried out for a period of six-months with baseline and post intervention evaluations. Participants (n=848) were secondary school students of ages of 14-19 years from four schools (clusters) in Brong Ahafo, Ghana. Students in the intervention group received health education intervention whereas those of the control group received no intervention. The intervention included information on cardiovascular diseases and its risk factors, motivation, and behavioral skills modules. At six months, a follow-up data using same questionnaire were collected after the intervention was completed. The generalized linear mixed model (GLMM) was used to assess the overall effects of the intervention.
Results
Of the 848 students, 836 completed the follow-up assessment immediately after six-month. The GLMM showed the intervention was significant in improving 6.85(p<0.001), 0.90(p<0.001), 0.94(p<0.001) higher total CVD knowledge, motivation, and behavioral skills scores respectively for the intervention group when compared to the control group.
Conclusions
The intervention was effective in increasing CVD knowledge, motivation, and behavioral skills of students in the intervention arm of the study. It is recommended that the health education module be implemented into secondary schools education curricula in Ghana to improve CVD knowledge, motivation, and behavioral skills. Equipping students with the IMB will reduce CVD risk factors and prevent the onset of CVDs in future.
