Culturally tailored smartphone apps are needed for weight control, especially for Hispanic and Brazilian Americans. Developing these evidence-based tools can improve diet, physical activity, and reduce obesity rates.
Area of Science:
- Public Health
- Health Informatics
- Behavioral Science
Background:
- Obesity affects 35% of US adults, projected to rise by 50% by 2030.
- Smartphone applications offer a low-cost method for disseminating weight control information.
- A gap exists in research-tested smartphone apps for weight control among culturally diverse populations.
Purpose of the Study:
- Highlight the need for culturally tailored smartphone apps for weight control.
- Provide recommendations for future research in this area.
- Examine specific needs for Hispanic and Brazilian Americans.
Main Methods:
- Commentary discussing the current landscape of weight control apps.
- Identification of characteristic dietary patterns and app absence for Hispanic Americans.
- Assessment of needs for Brazilian Americans, including Portuguese speakers.
Main Results:
- Smartphone apps show potential for improving diet, nutrition, physical activity, and reducing obesity.
- Few randomized controlled trials exist for stand-alone weight loss apps focusing on self-monitoring.
- No published studies address apps for weight loss in Hispanic or Brazilian Americans.
Conclusions:
- Low-cost, effective e-Health interventions are crucial for promoting healthy lifestyles in diverse populations.
- Weight loss apps should utilize evidence-based, behaviorally-theorized approaches.
- Further research is needed for culturally tailored, accessible weight loss strategies, particularly for non-English speakers and varying health literacy levels.
