Acompañamiento Nutricional con prototipo de chatbot en población con hipertensión y promoción de dieta DASH

Abstract

CONDITION FOR PROJECT PUBLICATION. The combination of personalized nutritional support and technology represents an innovative strategy to improve adaptability to the DASH diet in people with hypertension. To evaluate its effectiveness, an experimental, longitudinal, and mixed-method study was designed with 40 volunteers, divided into a study group and a control group, with a two-month intervention. The study group received continuous nutritional support based on coaching principles and access to the NutriSmart application with a chatbot, while the control group only received traditional nutritional guidance. Changes in body composition, blood pressure, and adaptability to the DASH diet were assessed using a nutrient scoring scale. The results show a significant improvement in blood pressure and greater adaptability to the DASH diet in the study group. Systolic blood pressure decreased by 8.56 mmHg in the study group, whereas in the control group, it only decreased by 5.63 mmHg. Additionally, 22.2% of the study group participants achieved high adaptability to the diet, compared to none in the control group, satisfaction level of 72% among the respondents, highlighting features such as pressure tracking, micronutrient visualization, and the link to WhatsApp to contact the nutritionist for specific questions It is concluded that the integration of technology and nutritional support enhances adaptability to the DASH diet and promotes hypertension control.
