The association between social development and population health: a cross-sectional study across countries of different economic growth

Abstract

Background Social Determinants of Health (SDH) are important in explaining why some countries enjoy better health than others. This empirical study highlights controversies in the literature on the relationship between socioeconomic development and health, and investigates how the relationship might vary in countries with different economic growth. Methods The sample consists of 172 countries, and recent cross-sectional data was collected from the World Bank’s “Data Bank”. Population health was proxied with life expectancy, infant mortality and under-five mortality, and sociooeconomic conditions were expressed with GNI/capita, unemployment rate, poverty, Gini index, educational attainment, public spending on health and physician density. Countries were categorized into three groups as low / lower middle-, upper middle- and high-income according to World Bank thresholds. Ordinary least squares regression was used to model the relationships. Results The association between socioeconomic conditions and health differed between countries of different economic development. Poverty, educational attainment, income inequality, and physician density were the strongest contributors to health. Higher economic development had a stronger relationship with health in richer countries, and government commitment to health care in poorer ones. Conclusion Based on evidence from studies such as this one, researchers and policymakers globally could commit to acting together on SDH, and to aligning resources from different sectors to formulate interventions aiming to improve population health.

Non-communicable diseases and the prospects of integrated behavioral health in India: current status and future directions

“…Poor neighborhood conditions, such as poor-quality housing, low-quality schooling, higher unemployment, and lack of safety, are associated with a higher risk of physical and mental health issues (Hernandez et al ., 2006; Mancini, 2021). A study suggested that the association between social determinants and health disparity across countries contributed to poverty, income inequality, educational attainment, and physician density (Kontodimopoulos, 2022). These disparities are even evident within countries and regions.…”

Impacts of cash transfer and “cash plus” programs on self- perceived stress in Africa: Evidence from Ghana, Malawi, and Tanzania

“…In Africa specifically, the number of CTs has tripled between 2000 and 2015 and are currently being implemented in 40 out of 48 countries ( World Bank Group, 2015 ). While the primary objective of cash transfers is poverty reduction and poverty-related outcomes, such as improved food security, there has been increased interest in examining secondary impacts on outcomes such as mental health, given poverty's potential role in the production of poor health outcomes ( Galea et al, 2011 ; Kontodimopoulos, 2022 ; Lim et al, 2012 ).…”
