Use of Text Messaging and Facebook Groups to Support the Healthy Children, Strong Families 2 Healthy Lifestyle Intervention for American Indian Families

BACKGROUND: Few obesity interventions have been developed for American Indian (AI) families despite the disproportionate risk of obesity experienced within AI communities. The emergence of mobile technologies to enhance intervention delivery could particularly benefit AI communities, many of which are hard to reach and underserved. OBJECTIVES: This study aimed to assess the use and perceptions of text messaging and Facebook to support delivery of the Healthy Children, Strong Families 2 (HCSF2) mailed healthy lifestyle/obesity prevention intervention and discuss lessons learned regarding intervention support via these platforms among AI participants. METHODS: From among AI families with young children (ages 2–5 y), 450 adult-child dyads were recruited from 5 rural and urban communities for a year-long intervention. Intervention content was delivered by mail and supported by text messaging and optional Facebook groups. Participants provided feedback on text message and Facebook components post-intervention, and Facebook analytic data were tracked. RESULTS: Self-report feedback indicated high satisfaction with both text messaging and Facebook, with tangible content (e.g., recipes, physical activity ideas) cited as most useful. Overall, participants reported higher satisfaction with and perceived efficacy of Facebook content compared with text messaging. Analytic data indicate the optional HCSF2 Facebook groups were joined by 67.8% of adult participants. Among those who joined, 78.4% viewed, 50.8% “liked,” and 22.6% commented on ≥1 post. Engagement levels differed by urban-rural status, with more urban participants “liking” (P = 0.01) and commenting on posts (P = 0.01). Of note, nearly one-third of participants reported changing phone numbers during the intervention. CONCLUSIONS: This study demonstrates high satisfaction regarding mobile delivery of HCSF2 intervention support components. Best practices and challenges in utilizing different mobile technologies to promote wellness among AI families are discussed, with particular focus on urban-rural differences. Future mobile-based interventions should consider the context of unstable technology maintenance, especially in low-resource communities. This work is part of the HCSF2 trial, which is registered at clinicaltrials.gov (NCT01776255).
