Something as simple as a text message can help people with diabetes control their condition.
Researchers at the University of Colorado sent text messages to patients receiving diabetes care at a community health center in Denver.
Three times a week for three months, participants were asked for blood sugar readings and they got reminders for doctor appointments.
Nearly 80 percent of the patients in the study responded to more than half the messages they received. Two-thirds provided blood sugar readings to researchers after receiving a reminder.
Participants said the program made them feel accountable for their health — it gave them social support, and it made them more aware of health information.
The study concludes that cell-phone text messaging may improve chronic disease management support beyond the clinic setting.
