Socioeconomic Status And Risk Of Cardiovascular Disease In 20 Low-Income, Middle-Income, And High-Income Countries: The Prospective Urban Rural Epidemiologic (Pure) Study, Annika Rosengren, Andrew Smyth, Sumathy Rangarajan, Chinthanie Ramasundarahettige, Shrikant I. Bangdiwala, Khalid F. Alhabib, Alvaro Avezum, Kristina Bengtsson Boström, Jephat Chifamba, Romaina Iqbal

Community Health Sciences

Background: Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status-wealth and education-differ among high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management.
Methods: In this large-scale prospective cohort …

Health Systems Readiness For Adopting Mhealth Interventions For Addressing Non-Communicable Diseases In Low- And Middle-Income Countries: A Current Debate, Anam Shahil Feroz, Muhammad Masood Kadir, Sarah Saleem

Community Health Sciences

In low-and-middle-income countries, epidemiologic transition is taking place very rapidly from communicable diseases to non-communicable diseases. NCDs mortality rates are increasing faster and nearly 80% of NCDs deaths occur in LMICs. Existing weak health systems of LMICs are undergoing a devastating human and economic toll as a result of increasing treatment costs and losses to productivity from NCDs. At the same time, the increasing penetration of mobile phone technology and the spread of cellular network and infrastructure have led to the introduction of the mHealth field. While mHealth field offers a great promise to prevent and control non-communicable diseases in …
