Age at first establishment of chronic hepatitis B virus infection and hepatocellular carcinoma risk : a birth order study.
It is frequently assumed that the risk of hepatocellular carcinoma related to hepatitis B virus is higher when chronic hepatitis B virus infection is acquired early in life.
This hypothesis has never been directly evaluated.
However, firstborn and secondborn children are exposed to common infections after their school enrollment, whereas later-born children are exposed much earlier, through their older siblings.
The authors analyzed sibship size and birth order data from a large case-control study of patients admitted to Athens, Greece, hospitals between April 1976 and October 1984.
