[Infant mortality in Brazil and deaths from acute myocardial infarction in the same generation]

Area of Science:

• Cardiovascular epidemiology
• Public health research
• Cancer epidemiology

Context:

• Low birth weight is a significant risk factor for cardiovascular diseases (CVDs), a leading cause of death globally and in Brazil.
• High infant mortality rates are historically linked to low birth weight.
• Brazil presents regional disparities in socioeconomic conditions and historical infant mortality rates.

Purpose:

• To compare mortality rates of acute myocardial infarction (AMI) between Brazil's Northeast and South regions in 2000.
• To investigate potential links between historical infant mortality rates and current AMI mortality.
• To examine regional differences in lung cancer mortality.

Summary:

• Acute myocardial infarction mortality was substantially higher in Southern Brazil (60.8 males, 41.2 females per 100,000) than in the Northeast (26.4 males, 19.2 females per 100,000).
• Lung cancer mortality also showed higher rates in the South compared to the Northeast for both sexes.
• Persistent socioeconomic and infant mortality differences between regions complicated the assessment of low birth weight's impact on AMI mortality.

Impact:

• Highlights significant regional disparities in mortality from major non-communicable diseases within Brazil.
• Underscores the complex interplay of socioeconomic factors, historical health indicators, and current disease burdens.
• Suggests that improvements in quality of life have not fully mitigated the long-term health consequences associated with early life conditions.
