A nine-month trial of a text message-based self-management program developed by the National Institute for Health Innovation (NIHI) at the University of Auckland has seen participants with poorly controlled diabetes improve their HbA1c levels over usual care.

The Self-Management Support for Blood Glucose (SMS4BG) program, which provides a tailored package of text messages, has previously been shown to be appreciated by participants and to support them to manage their condition better.
