Can the gap in Aboriginal outcomes be explained by DOHaD.

Area of Science:

• Public Health
• Developmental Biology
• Indigenous Health

Background:

• Significant health disparities exist between Aboriginal and Torres Strait Islander People and non-Aboriginal Australians.
• Aboriginal babies face higher rates of low birth weight and growth restriction, indicating potential intrauterine challenges.
• The Developmental Origins of Health and Disease (DOHaD) hypothesis links early life environment to later non-communicable disease risk.

Purpose of the Study:

• To explore the role of DOHaD in understanding health disadvantages experienced by Aboriginal Australians.
• To review literature associating fetal growth (as a proxy for intrauterine environment) with offspring health outcomes.
• To provide insights into health disparities between Indigenous and non-Indigenous children.

Main Methods:

• This study is a narrative review of existing literature.
• It focuses on the association between fetal growth and perinatal health, early development, and childhood education.
• The review examines the impact of the intrauterine environment and developmental programming.

Main Results:

• The literature largely supports the DOHaD hypothesis in the context of Aboriginal Australians.
• Diminished fetal growth is linked to adverse outcomes in offspring, including perinatal health and developmental issues.
• Understanding these links can illuminate pathways to persistent health disadvantages.

Conclusions:

• The DOHaD hypothesis offers a valuable framework for understanding health disparities in Aboriginal Australians.
• Implications extend to policy-making for Indigenous populations globally facing similar disadvantages.
• Further research into the intrauterine environment's role is crucial for improving Indigenous child health outcomes.
