Abstract: In many countries around worldwide, mobile health technology is increasingly being used and it may be a convenient and cost-effective way to support healthy behaviors for preventive health care.

In-depth interviews were conducted among ten participants of those who improved any behavior or metabolic risk factors of non-communicable disease (NCDs) and who did not change after the intervention.
