Drivers of NCDs in South East Asia Region (SEAR)Countries

  In SEAR Countries, globalization, unplanned urbanization, poverty, poor health systems and social inequities are major reasons for Non-Communicable Diseases.

  Wide range of people’s health outcomes and NCDs are influenced by socioeconomic determinants.

Major Socioeconomic Determinants



  Poor health infrastructure

  Social inequities

  Life expectancy

  Urbanization and globalization.

Ageing Population

  Due to epidemiological transition (change in disease patterns from infectious diseases to NCDs) and demographic transition (increased longevity and a rise in the ageing population) NCDs have emerged as a public health problem in this region.

  As a result of marked reduction in infant and child mortality and control of communicable diseases, people are living longer in this region.
