摘要：Background and Objective: Current efforts to overcome hypertension have been predominantly based on medical treatment. Nutritional education and local food use are still limited in efforts to lower blood pressure . This study was conducted to analyze the effect of nutritional education intervention and the provision of chayote on changes in blood pressure of pre-diabetic high school teachers. Methodology: This research study is an experiment consisting of a sample of high school teachers (SMA) with pre-diabetes in Palu city. The number of subjects per group was 25 people and they were categorized as the following: Group I = Intervention of instant chayote, Group II = Nutrition education intervention and Group III = Nutrition education intervention and provision of chayote. Systolic and diastolic blood pressure was measured before and after intervention. Data analysis were performed using pairwise t-test and Wallis crucial test and significance was considered at p<0.05. Results: Change in the mean and standard deviation of systolic blood pressure after intervention with instant infusion of chayote was 15.24±10.54 mm Hg (p = 0.00), after nutrition education intervention was 3.12±12.34 mm Hg (p = 0.190) and intervention in combination of nutrition education and instant chayote were 14.48±12.00 (p = 0.00). The change in diastolic blood pressure after intervention with the administration of siam gourd was 11.24±8.29 mm Hg (p = 0.00), nutritional education intervention was 1.88±10.33 mm Hg (p = 0.253) and intervention in combination of nutritional education and chayote was 6.84±11.76 mm Hg (p = 0.005). Conclusion: Instant chayote interventions combined with nutritional education may significantly decrease systolic and diastolic blood pressure s in pre-diabetic high school teachers.
