Development and Preliminary Feasibility of iByte4Health: A Mobile Health (mHealth) Pediatric Obesity Prevention Intervention to Engage Parents with Low-Income of Children 2-9 Years.

This research describes the development and preliminary feasibility of iByte4Health, a mobile health (mHealth) obesity prevention intervention designed for parents with a low-income of children 2-9 years of age. Study 1 ( = 36) presents findings from formative work used to develop the program. Study 2 ( = 23) presents a 2-week proof-of-concept feasibility testing of iByte4Health, including participant acceptability, utilization, and engagement. Based on Study 1, iByte4Health was designed as a text-messaging program, targeting barriers and challenges identified by parents of young children for six key obesity prevention behaviors: (1) snacking; (2) physical activity; (3) sleep; (4) sugary drinks; (5) fruit and vegetable intake; and (6) healthy cooking at home. In Study 2, participants demonstrated high program retention (95.7% at follow-up) and acceptability (90.9% reported liking or loving the program). Users were engaged with the program; 87.0% responded to at least one self-monitoring text message; 90.9% found the videos and linked content to be helpful or extremely helpful; 86.4% found text messages helpful or extremely helpful. iByte4Health is a community-informed, evidenced-based program that holds promise for obesity prevention efforts, especially for those families at the increased risk of obesity and related disparities. Future work is warranted to test the efficacy of the program.
