⚡ Quick Summary

A recent study evaluated the relative validity of the Keenoa mobile application, an artificial intelligence-enhanced tool for dietary assessment, against the validated ASA24 platform among adolescents. The findings suggest that Keenoa provides comparable results for energy and macronutrient intakes, while highlighting some discrepancies in micronutrient reporting.

🔍 Key Details

• 👥 Participants: 141 adolescents aged 11-15 years
• 📅 Study Design: Randomized crossover design over three days
• 🛠️ Tools Used: Keenoa mobile app and ASA24 web-based platform
• 📊 Key Metrics: Energy intake, macronutrients, and micronutrients

🔑 Key Takeaways

• 📈 Energy intake reported by Keenoa (1978 ± 425 kcal/d) was similar to ASA24 (1976 ± 451 kcal/d) with no significant difference (P = 0.95).
• 🔍 Macronutrient intakes showed no significant differences between the two tools.
• 📉 Fiber intake was reported higher with Keenoa, while sodium, calcium, and vitamin D were lower (P values < 0.001-0.025).
• 🔗 Deattenuated correlations between tools ranged from r = 0.77 to 1.00 (all p < 0.01).
• 📊 Agreement scores (weighted Cohen κ) ranged from 0.22 to 0.42 (all p < 0.001).
• ✅ Completion rates were higher for Keenoa (85.8%) compared to ASA24 (55.3%) (P < 0.01).
• 🌟 Keenoa may help reduce attrition bias in dietary assessments.
• 🔮 Future validation with objective biomarkers is needed to establish true validity.

📚 Background

Adolescence is a pivotal stage for growth and development, where nutritional choices can significantly influence long-term health outcomes. Traditional dietary assessment methods often fall short when applied to large adolescent populations, necessitating innovative solutions. The advent of mobile applications enhanced by artificial intelligence presents a promising avenue for more accurate and user-friendly dietary tracking.

🗒️ Study

This study was conducted within the framework of the CHILD Cohort Study, involving 141 adolescents aged 11-15 years. Participants were asked to track their food intake using both the Keenoa app and the ASA24 platform over three days, including two weekdays and one weekend day. The aim was to assess the relative validity of Keenoa in comparison to the established ASA24 method.

📈 Results

The results indicated that the Keenoa application demonstrated strong to moderate relative validity against ASA24 for energy, macronutrient, potassium, and iron intakes. However, discrepancies were noted in the reporting of fiber, sodium, calcium, and vitamin D, suggesting that while Keenoa is a reliable tool, it may require further refinement in certain areas.

🌍 Impact and Implications

The findings from this study highlight the potential of the Keenoa mobile application to facilitate dietary assessments among adolescents, thereby improving data collection in nutritional research. By reducing attrition bias and enhancing user engagement, such tools could lead to more accurate dietary data, ultimately informing public health strategies aimed at improving adolescent nutrition and reducing chronic disease risk.

🔮 Conclusion

The Keenoa mobile application represents a significant advancement in dietary assessment technology for adolescents. With its demonstrated validity in tracking dietary intake, it holds promise for future research and public health initiatives. Continued validation efforts, particularly using objective biomarkers, will be essential to fully establish its efficacy and reliability in diverse populations.
