MONDAY, Feb. 8 (HealthDay News) -- Consuming two or more soft drinks per week may be associated with a higher risk of pancreatic cancer in middle-aged and elderly Chinese individuals, although results from previous studies in primarily Caucasian populations have been mixed, according to a study in the February issue of Cancer Epidemiology, Biomarkers & Prevention.
Noting that sugary soft drinks can expose the pancreas to high insulin levels that may lead to cancer, Noel T. Mueller, of the Georgetown University Medical Center in Washington, D.C., and colleagues assessed the consumption of soft drinks and juice and the risk of pancreatic cancer in 60,524 Chinese men and women in Singapore (mean age, 57.1 years).
After up to 14 years of follow-up, the researchers recorded 140 cases of pancreatic cancer. After adjusting for potential confounding factors, individuals who consumed two or more soft drinks per week compared with no soft drinks had a significantly higher risk of pancreatic cancer (hazard ratio, 1.87). There was no significant association found between juice consumption and pancreatic cancer.
"Regular consumption of soft drinks may play an independent role in the development of pancreatic cancer," the authors conclude.
