Immigrant Latino parents demonstrated high interactivity with pediatric primary care text messaging intervention

The majority of Latino immigrants have been shown to have a mobile phone. Cellular phones offer a low-cost method of reaching larger populations and have the potential for increased tailoring and interactivity. This supports the development of mHealth interventions to address healthcare disparities in this population. In this study we sought to evaluate the feasibility and acceptability of interactive Spanish-language text messages sent throughout a child's first year of life in a low-income, limited-English proficient (LEP) Latino population to support families in accessing and using pediatric primary care more effectively.

Participants (n=79) received interactive text messages over a period of 12 months as a part of a multi-modal mHealth intervention conducted at an urban academic pediatric primary care practice. Inclusion criteria were: singleton infant <2 months of age, enrollment in public health insurance, parent age >18, parent preferred healthcare language of Spanish, and at least one household cellular phone. Interactive text messages were designed to promote increased healthcare engagement and prompted participant responses through preprogramed algorithms. Text message sequences included clinic appointment reminders, support for obtaining medicine and completing referral appointments, monitoring of illness care needs and use, and parent support program reminders. Descriptive analyses were used to examine text message volume, usability, and participant response to text sequences.

Among participants, mean parent age was 30.1 years (SD: 6.1 years); mean years in the US was 7.5 years (SD: 5.1 years). 63.3% of parents had less than a high school education and 84.8% of parents had possible/high likelihood of limited health literacy. Participants completed the majority of sequences with appointment reminder sequences having the quickest response time. The top quartile of responders completed 88.3% of sequences; lower educational attainment was associated with lower text message sequence completion. Participants rated the program positively, especially the appointment reminders.

LEP Latino parents successfully engaged with interactive Spanish-language text sequences and parent acceptability was high. This study demonstrates feasibility for interventions employing this technology. Text message interventions may be a feasible approach to reduce healthcare disparities and costs for vulnerable populations.
