Low birth weight: a possible risk factor also for liver diseases in adult life?

Area of Science:

• Perinatal Medicine
• Hepatology
• Developmental Origins of Health and Disease (DOHaD)

Background:

• Birth weight is a critical indicator of infant health and survival, with low birth weight (LBW) associated with various long-term health problems.
• LBW is a known risk factor for metabolic disorders, including atherosclerosis, diabetes mellitus, hypertension, and obesity.
• Limited research exists on the specific link between LBW and liver diseases, despite LBW indicating an unfavorable intrauterine environment.

Purpose of the Study:

• To explore the potential associations between low birth weight and the development of liver diseases in adulthood.
• To review existing evidence supporting a hypothesis linking LBW to liver conditions such as hepatitis, non-alcoholic fatty liver disease, cirrhosis, hepatoblastoma, and hepatocellular carcinoma.
• To note potential associations between LBW, hepatitis vaccination, and pediatric parenteral nutrition.

Main Methods:

• Literature review and evidence synthesis.
• Discussion of epidemiological data and etiological hypotheses.
• Exploration of indirect and direct associations between LBW and liver pathology.

Main Results:

• Low birth weight is associated with a wide range of metabolic and developmental abnormalities.
• Evidence suggests a potential link between LBW and increased risk for various liver diseases in later life.
• Associations between LBW and hepatitis vaccination/pediatric nutrition were also identified.

Conclusions:

• Low birth weight may serve as an indicator for increased susceptibility to liver diseases in adulthood.
• Further investigation is warranted to elucidate the mechanisms connecting LBW, intrauterine conditions, and adult liver health.
• Understanding these links could inform preventative strategies for individuals born with low birth weight.
