Introduction

  • Omran’s theory
  • Introduction of the 4th stage of epidemiologic transition: maximum point of convergence of life expectancies (85 years) increase due to the achievements in the treatment of cardiovascular diseases
  • Goal of the article: study the exceptions observed since 1960s in the general trend of increasing life expectancy

From Convergence to Divergence

  • Rise of man-made diseases was curbed by efficient policies
  • Revolution in the treatment of cardiovascular diseases
  • After WWII, most countries made huge progress and joined the general trend of convergence of increased life expectancy
  • However, countries in Africa weren’t able to reach a pace of progress sufficient to reduce the gap separating them from developed countries
  • Many countries of tropical Africa are advancing at a much slower pace than other countries with similar life expectancy levels
  • AIDS epidemic triggered a sharp decrease in life expectancy levels in many African countries
  • Exceptions: Sub-Saharan Africa + Eastern Europe

Sub-Saharan Africa: An Unfinished Second Phase

  • None of the countries in Sub-Saharan Africa have been able to catch up with developed countries
  • Some countries had their life expectancy declined over the last 2 decades
  • 2 problems:
    • These countries have failed to make rapid advances in the field of health
    • All progress if any stopped towards the end of the 1980s due to AIDS, the economic crisis, and the reappearance of infectious diseases

Slower Progress than Might Have Been Expected

  • In almost all African countries: infant and child mortality declined significantly at a slow pace
  • Examples: Niger, Ghana
  • In most countries in Sub-Saharan Africa: infant and child mortality did not decrease rapidly
  • Arrival of AIDS: pull many African countries back to life expectancy levels that were prevalent at the beginning of the second transition
  • Impact of wars + political violence, which is frequent in Africa
  • Rwanda’s genocide: reduced life expectancy
  • Second phase of the epidemiologic transition is far from having ended in Africa due to: slowness of health care advances + impact of AIDS

Eastern Europe: The Fourth Phase Has Yet to Begin

Reemergence of the East-West divergence

  • None of the Eastern European countries took part in the health improvements made by most industrialized countries since the 1970s

Specific Eastern Europe trends

  • Countries of the former Soviet Union: male life expectancy underwent a sharp decline and female life expectancy stagnated
  • Life expectancy started to fluctuate in 1985

Atypical Age Patterns

  • Decline of life expectancy in Eastern Europe: linked to the uncommon distortion of the structure of age-specific mortality
  • Excess mortality in the ages 25 and 55 both for male and female

The Importance of Cardiovascular and Man-Made Diseases

  • Eastern countries were unable to curb the increase in mortality due to cardiovascular diseases
  • Mortality related to alcohol consumption
  • Increase in man-made diseases: deteriorated the health situation
