Mobile phones are a promising way to communicate health information to low-income populations, according to a new study from the Brown School at Washington University in St. Louis. The findings came from a survey of nearly 2,000 callers to United Way 2-1-1 Missouri, which connects callers to social services. Nearly three-fourths of those sampled owned a mobile phone, and most used their phones for text messaging. “It appears feasible to use mobile technology for health information and interventions in diverse low-income populations,” wrote the study’s lead author, Dr. Jason Purnell, assistant professor at the Brown School. “The 2-1-1 system may be a promising partner in national efforts to address health disparities.” The results of the study were published online November 7 in the American Journal of Health Promotion.
