Abstract
This article is a review of global health literature, emphasizing the evolution in health terminology in recent decades and noteworthy research areas of global health. This review identifies global inequality and disease-related stigma as key social determinants of health and central problems improving health outcomes. Within global health, there is a growing discourse surrounding health disparities, particularly among the world's most disadvantaged populations. Additionally, the field notes an increase in global health nonprofits, international governmental organizations (IGOs), and regulatory bodies. As such, this paper examines the scope of empirical global health research with consideration of inequality and stigma as well as the role of nongovernmental organizations (NGOs) in health outcomes for the developing world. The review also discusses the role of IGOs and global health regulatory bodies in shaping development and health outcomes. A broad review of literature finds that although chronic noncommunicable diseases (NCDs) are currently the largest cause of poor health in the world's most impoverished nations, these are largely untargeted by NGO efforts, which may exacerbate the state of global inequality. However, the impact that NGOs could have on ameliorating the effects of NCDs remains understudied and is a promising direction for future scholarly efforts.
