An SMS Text Message-Based Type 2 Diabetes Prevention Program for Hispanic Adolescents With Obesity: Qualitative Co-Design Process

Communicating physical activity messages with adolescents: what works? A scoping review with stakeholder consultation

BACKGROUND

Global levels of adolescents' physical inactivity are cause for concern, despite the well-documented health benefits of physical activity (PA). Addressing the messaging of PA is one approach to improve PA knowledge. While increased knowledge does not necessarily lead to behavior change, physically active students have better knowledge of the health benefits of PA. Recently, researchers have highlighted the need for an effective communication strategy for PA messages. This review aimed to summarize the state of the available evidence about the operationalization of communicating PA messages, the evaluation, and effectiveness of PA messages.

METHODS

The Levac six steps and Joanna Briggs Institute methodological guidance for scoping reviews were followed. Five databases were searched up until April 8th 2024. Both title and abstract and full-text screening were piloted whereby 10% of the total articles were double-screened and the remainder were completed by CG. Data were extracted and a data-based convergent synthesis design was used following qualitative synthesis methods. Finally, a consultation with key stakeholders was held to confirm the findings concerning practical relevance.

RESULTS

A total of 19,412 articles were identified from searches, 94 full texts were included in the final analysis, corresponding to 80 individual studies. The evidence confirms that there are many factors to consider when communicating PA messages and evaluating their effectiveness. Inconsistencies exist regarding the timing and frequency of message delivery and the evaluation of effective communication. When communicating PA with adolescents, messages commonly focus on the benefits of PA and strategies to overcome barriers and are commonly delivered in the school setting by researchers or school stakeholders i.e. teachers, peers. Messages should be concise, positively framed, support adolescent autonomy, and utilize different messaging platforms and techniques to avoid staleness.

CONCLUSIONS

There is a lack of a standardized approach to communicating PA messages with adolescents making evaluation and comparison challenging. Future research should focus on developing guidance to facilitate the effective communication of PA messages with adolescents.

Advancing Type 2 Diabetes Prevention through Text-Messaging Interventions: A Narrative Review

PURPOSE OF REVIEW

Text-messaging interventions effectively prevent and manage numerous health conditions. This scoping review evaluates recent literature on text-messaging interventions focused on diabetes prevention, highlighting their development, associated outcomes, reach, and potential sustainability.

RECENT FINDINGS

A total of 28 studies met eligibility criteria and were included in this review. Text-messaging was often used as a primary intervention method, focusing on promoting weight loss through physical activity and dietary changes. Studies also explored hybrid approaches integrating text-messaging with in-person sessions or other digital platforms. Intervention development involved multi-phase content creation, often leveraging established diabetes prevention curricula. Studies generally reported high feasibility and acceptability, although effectiveness was mixed. Cost-effectiveness comparisons favored text-messaging over traditional in-person programs. Implementation strategies aligned interventions with existing healthcare workflows, facilitating scalability and integration into routine care practices. Text-messaging interventions demonstrate considerable promise but require further refinement to ensure their effectiveness, particularly in enhancing participant engagement to ensure effectiveness and sustainability. Future research should focus on refining intervention content, integrating interactive features, and expanding cost-effectiveness evaluations to support broader implementation in real-world settings.

Feasibility of Fit24, a Digital Diabetes Prevention Program for Hispanic Adolescents: Qualitative Evaluation Study

BACKGROUND

Digital health interventions are promising for reaching and engaging high-risk youth in disease prevention opportunities; however, few digital prevention interventions have been developed for Hispanic youth, limiting our knowledge of these strategies among this population.

OBJECTIVE

This study qualitatively assessed the feasibility and acceptability of Fit24, a 12-week goal-setting intervention that uses a Fitbit watch (Fitbit Inc) and theoretically grounded SMS text messages to promote physical activity and sleep among Hispanic adolescents (aged between 14 and 16 years) with obesity.

METHODS

After completing the intervention, a subsample of youth (N=15) participated in an in-depth interview. We categorized the themes into dimensions based on participant perspectives using the Practical, Robust Implementation, and Sustainability Model (PRISM) framework.

RESULTS

Participants shared positive perceptions of wearing the Fitbit and receiving SMS text messages. Youth were highly engaged in monitoring their behaviors and perceived increased activity and sleep. Almost all youth organically received social support from a peer or family member and suggested the use of a group chat or team challenge for integrating peers into future interventions. However, most youth also expressed the need to take personal responsibility for the change in their behavior. Barriers that impacted the feasibility of the study included the skin-irritating material on the Fitbit watch band and environmental barriers (eg, lack of resources and school schedules), that limited participation in activity suggestions. Additionally, sync issues with the Fitbit limited the transmission of data, leading to inaccurate feedback.

CONCLUSIONS

Fit24 is a promising approach for engaging Hispanic youth in a diabetes prevention program. Strategies are needed to address technical issues with the Fitbit and environmental issues such as message timing. While integrating peer social support may be desired by some, peer support strategies should be mindful of youth's desire to foster personal motivation for behavior change. Findings from this study will inform future diabetes prevention trials of Fit24 and other digital health interventions for high-risk pediatric populations.
