Study on the Satisfaction of Users With Nutrition Apps in South Africa

Introduction: Nutrition-related apps are increasingly significant for promoting healthy eating. Given South Africa's high prevalence of obesity and non-communicable diseases, including cardiovascular diseases and diabetes, evaluating users’ perceptions of the effectiveness of these apps is crucial. Methods: In 2019, a quantitative descriptive survey was conducted with 150 Johannesburg residents aged 18–38, focusing on Millennials and Generation Z. Participants used a nutrition-related app and completed a self-administered electronic questionnaire via Google Forms. The survey assessed socio-demographic characteristics, behaviour change and user experience with the app using a 5-point Likert scale. Data were analysed using SPSS version 27. Results: The sample was diverse, with 56% female and 44% male, predominantly aged 18–23 years (40%). The ethnic breakdown was 47.3% Black, 22.7% White and 30% coloured, Indian and Asian. Income levels varied, with 30% earning between R5000 and R15,000 per month. Approximately 69% of participants reported increased motivation and knowledge about healthy eating due to the app. However, up to 25% observed no change in their perceptions of diet-related health risks or others’ eating habits. Feedback indicated that the apps were generally easy to use, convenient and helpful, though some users found them less exciting. Conclusion: Although this study was conducted only in Johannesburg, it already reveals that nutrition-related apps show promise for improving healthy eating habits among a digitally engaged population in South Africa. Their user-friendly design and broad accessibility suggest potential for continued use and impact. Future research should focus on enhancing user engagement and excitement to maximize the benefits of these digital health tools.
