Knowledge, practice and attitudes of primary school children towards healthy diet in Dikgale Village, Limpopo Province, South Africa

Abstract

The aim of this study was to investigate knowledge, attitudes and practices of primary school children towards healthy diet in Dikgale Village, Limpopo Province, South Africa. This study was an intervention study at eight primary schools in Dikgale Village. The study used both qualitative and quantitative research where mixed methods research design. A total of 324 participants consisting of Grades 6 and 7 males and females was purposively selected. These participants were divided into experiment and control group after pre-test but before the intervention. This study used a 27-item questionnaire which covered, knowledge on healthy diet, attitudes, practices, subjective norm and self-efficacy questions as well as focus group interviews. The main findings of the study comprise the following: (i) Learners in the experiment condition did not reflect more health-related practices (F(1.315)=0.20; p>887), i.e., when considering co-variables and changes in health attitude, subjective norm and self-efficacy; and (ii) After intervention, there was a significant increase (F(1.315)=115.72; p<0.001) in health-related knowledge on the experiment group, i.e., when considering co-variables and changes in health attitude, subjective norm and self-efficacy. In addition to this significant increase, 58.3% of the differences between both groups seemed related to the intervention with regard to changes in knowledge acquisition. However, there was no significant increase on both health knowledge and health practices on the control group. The results suggested that, even if there can be changes in knowledge due to intervention, healthy practices may be difficult to change mainly because knowledge alone cannot decrease the prevalence of health-related conditions. As a result, this study suggest that the curriculum should cover Food knowledge practice so as to persuade learners to practice healthy diet. Also, School Management Teams (SMTs) and School Governing Bodies (SGBs) should play their role in emphasizing the importance of Food-Based Dietary Guidelines in schools. Future interventions are therefore encouraged to include a moderate intensity intervention by trained professionals and feasibility of involving educators, SGBs and SMTs, particularly in policy adherence. Therefore, this study proposed a healthy food intervention strategy incorporating the Theory of Planned Behaviour in order to justify the knowledge, attitude and practices of children in healthy diet. Intervention should adopt the Training Partnership Model wherein children, parents, educators are trained by health professional on adherence to healthy diet.
