Led by researchers at Harvard-affiliated  Brigham and Womens Hospital, the observational study included nearly 100,000 postmenopausal women from the Womens Health Initiative. Participants were followed for a median of more than 20 years.

 

Researchers looked at self-reported liver cancer incidence and death due to chronic liver diseases such as fibrosis, cirrhosis, or chronic hepatitis, which were further verified by medical records or the National Death Index.

 

A total of 98,786 postmenopausal women were included in the final analyses. The 6.8 per cent of women who consumed one or more sugar-sweetened beverages daily had an 85 per cent higher risk of liver cancer and 68 per cent higher risk of chronic liver disease mortality compared to those who had fewer than three sugar-sweetened beverages per month.

 

“To our knowledge, this is the first study to report an association between sugar-sweetened beverage intake and chronic liver disease mortality,” said first author Longgang Zhao of Brighams Channing Division of Network Medicine.

 

“Zhao is a postdoctoral researcher who works with senior author Xuehong Zhang in the Channing Division.

“Our findings, if confirmed, may pave the way to a public health strategy to reduce the risk of liver disease based on data from a large and geographically diverse cohort.”

 

The authors note that the study was observational, and causality cannot be inferred and relied on self-reported responses about intake, sugar content and outcomes.

 

More studies are needed to validate this risk association and determine why sugary drinks appeared to increase the risk of liver cancer and disease.

 

Furthermore, more research is needed to elucidate the potential mechanisms by integrating genetics, preclinical and experimental studies, and -omics data.
