The equitable provision of healthcare entails the distribution of resources and other processes to overcome health inequality. The concept of heath equity suggests that differences in social and economic backgrounds of people affect their ability to lead the lives they choose to live. Following a review of what is known about health equity, social determinants of health equity and the role of mobile health, this paper investigates the relationship between mHealth, social inequalities in life expectancy and in education on Human Development and Health and Wellbeing. The analysis discovers a significant relationship between mHealth, social inequalities in human development and health outcomes. These findings have important implications for the use of mHealth applications to achieve health equity. The contribution of this paper is in understanding the role of social inequalities in and mHealth in enabling people to bring about improvements in the lives they lead and in their health outcomes.
