Thesis Abstract
The increasing recognition of genetic factors in individual dietary responses underscores the necessity for personalized nutrition interventions; however, existing dietary recommendation systems largely adopt a generalized approach that fails to account for genetic variability, resulting in suboptimal health outcomes. This study aims to develop and evaluate a mobile application that offers personalized dietary recommendations based on users’ genetic data, thereby enhancing nutritional compliance and health management. The specific objectives include (1) designing and implementing a secure, user-friendly mobile app capable of integrating genetic data with dietary preferences, (2) establishing a comprehensive algorithm to generate tailored dietary advice using genomic markers linked to nutrient metabolism, and (3) assessing the app’s usability, accuracy, and potential health benefits among a target population. The research adopts a mixed-methods design, combining quantitative and qualitative approaches to ensure comprehensive evaluation. The population consists of 300 adult individuals aged 25–45 from urban health clinics, recruited through stratified random sampling to ensure demographic diversity. Genetic data collection is facilitated via buccal swab samples analyzed through high-throughput genotyping technology, focusing on variants known to influence nutrient absorption, such as MTHFR and FTO genes. Data on dietary habits and health status are gathered through structured questionnaires and clinical assessments. The app’s algorithm development is grounded in the Health Belief Model and the Precision Nutrition framework, providing theoretical underpinnings for behavior change and tailored interventions. Quantitative data analysis employs descriptive statistics, multiple regression analysis to determine predictors of dietary adherence, and paired t-tests to examine pre- and post-intervention health metrics. The qualitative component involves thematic analysis of user feedback to identify usability issues and user acceptance factors. It is anticipated that the mobile app will demonstrate high usability scores and significant improvement in dietary adherence and relevant health indicators, such as body mass index and serum nutrient levels, among users over a three-month period. The application’s ability to accurately translate genetic data into practical dietary recommendations is expected to substantially enhance dietary compliance, thus advancing personalized nutrition science. This research contributes to the growing body of knowledge by integrating genomic data with mobile health technology, demonstrating the feasibility and effectiveness of genetically tailored dietary guidance within everyday health management. Furthermore, it offers a scalable model for developing personalized nutrition tools applicable in diverse healthcare settings. The main conclusion emphasizes that tailored dietary recommendations based on genetic information delivered through a mobile platform hold substantial promise for improving dietary behaviors and health outcomes. Recommendations include broader validation studies across different population groups, incorporation of additional genetic markers, and integration with electronic health record systems to facilitate personalized interventions at scale. Future research should also explore long-term adherence outcomes and cost-effectiveness analyses to optimize implementation strategies in clinical and community health contexts.
Thesis Overview
This research focuses on creating a mobile application that provides personalized dietary advice based on an individual's genetic information. The idea is that by understanding a person's unique genetic makeup, we can recommend diets that are more effective for their health, metabolic needs, and potential disease risks. This approach recognizes that people respond differently to the same foods, and traditional one-size-fits-all dietary guidelines may not be optimal for everyone. The project aims to address a gap in current nutrition practices where personalization is limited, and genetic data is seldom integrated into dietary recommendations for the general population.
The researcher will first review existing studies on nutrigenomics, which is the science of how genes and nutrition interact. Then, the project will involve designing a mobile app that collects basic health data and genetic information from willing participants. These participants will be recruited from a local community, with an initial target sample size of 200 individuals, ensuring diversity in age, gender, and health status. Data collection will include genetic testing through saliva samples, which will be analyzed using genotyping techniques to identify variants linked to dietary responses. The app will also gather dietary habits, lifestyle, and health data via questionnaires.
The data analyzed will include genetic markers, dietary intake, and health outcomes. Statistical techniques such as regression analysis and clustering will be used to identify patterns and generate personalized recommendations. The study will validate the app's recommendations through feedback and follow-up surveys, looking for improvements in dietary compliance and health markers.
This research is expected to contribute new knowledge on how mobile technology and genetic data can work together to provide tailored dietary advice, making nutrition more precise and individualized. The final aim is to produce a functional prototype of the app that healthcare professionals and individuals can use to improve dietary choices, leading to better health outcomes. The study’s findings could pave the way for wider adoption of genetics-based nutrition guidance in everyday health management.
