9, 10, 11 and 12 However, in a recently published meta-analysis
on education and health, based on nutritional interventions and physical activity with obese children, the results see more indicated that the interventions showed good results concerning blood pressure control and decrease in waist measurements, but some did not show a positive response regarding the prevention of childhood obesity.13 In search for solutions to prevent obesity in childhood and adolescence, the self-care stimulus is emphasized; for that, it is necessary to develop tools that are easily applicable in children, which will be directed to verifying what knowledge they have regarding healthy habits and foods that are healthy for the pediatric population. There are currently several tools that provide valid measures of food and nutrient Epacadostat order consumption. However, some children have difficulties in completing some of the tools, due to cognitive problems. Therefore, brief and easily-applicable tools can contribute to the development of preventive
strategies and to the evaluation of the effectiveness of intervention programs. Considering these facts, this study aimed to develop a questionnaire on the knowledge of healthy habits and risk factors for cardiovascular disease, and assess its validity and reproducibility. The tool was developed in five stages: literature review, selection of variables, expert evaluation, pilot study, and evaluation of Tryptophan synthase psychometric properties. The literature review was the base for the tool development, with the identification of studies on knowledge regarding healthy habits and risk factors for cardiovascular disease.9, 10 and 14 The tool was constructed in collaboration with health professionals (a pediatric cardiologist, an educational psychologist, a nurse, a nutritionist, and a physical educator). The first version was sent to three experts in the areas of nursing and education who have extensive experience in maternal and child health, so they could assess
the relevance of the items, the language, and the measurement scales used, and provide suggestions for the incorporation of other items. Subsequently, the pilot study was performed with 38 students who did not participate in the final study. All were elementary school students from public schools in Porto Alegre. The questionnaire was applied in different ways, in order to determine the best technique for performing the data collection. During the questionnaire application, students were instructed to ask for the researcher’s help when they had difficulty in understanding the questions. In case of doubt, the researcher talked to the student, clarified the doubt, and wrote down the question number on the tool, as well as the student’s doubt, for possible reformulations.
