Brief Summary

The goal of this clinical trial is to learn if the "Smart Nurse" artificial intelligence-supported mobile application improves nutrition, exercise, and sleep behaviors in high school students aged 14-18 years. The main questions it aimed to answer are:

• Did the "Smart Nurse" app improve healthy nutrition and exercise behaviors in adolescents?
• Did the "Smart Nurse" app improve sleep quality in adolescents?
• Did the "Smart Nurse" app lower body mass index (BMI) and waist circumference in adolescents? Researchers compared participants who used the "Smart Nurse" app to participants who did not use the app to see if the app improved health behaviors. Participants:
• Used the "Smart Nurse" mobile app every day for 12 weeks
• Recorded their daily meals, physical activity, and sleep time in the app
• Received personalized health messages based on their data
• Completed health surveys and body measurements at the beginning and end of the study

Outcome Measures

Primary Outcomes (1)

• Nutrition-Exercise Behavior Scale (NEBS) Subscale Scores

  Change in four subscale scores of the Nutrition-Exercise Behavior Scale (NEBS): healthy nutrition-exercise behavior, unhealthy nutrition-exercise behavior, psychological/dependent eating behavior, and meal regularity. Higher scores on healthy nutrition-exercise and meal regularity subscales indicate better behaviors. Higher scores on unhealthy nutrition-exercise and psychological eating subscales indicate worse behaviors.

Interventions

Smart Nurse Mobile Application BEHAVIORAL

An artificial intelligence-supported mobile health application designed for adolescents. Participants recorded their daily nutritional intake, physical activity steps, and sleep duration in the application every day for 12 weeks. The AI module analyzed the entered data according to international health guidelines (WHO Physical Activity Guidelines 2020, Turkey Nutrition Guidelines, National Sleep Foundation recommendations) and generated personalized nursing guidance messages. The application included four modules: nutrition tracking, exercise tracking, sleep tracking, and AI-based feedback.
