Summary
Gallstone disease risk factors show overweight as a significant risk and alcohol consumption as a protective factor. Higher parity and older age at first birth also increase gallstone risk in women.
Area of Science:
- Gastroenterology
- Epidemiology
- Public Health
Background:
- Cholelithiasis (gallstones) is a common condition with multifactorial etiology.
- Identifying modifiable risk factors is crucial for prevention strategies.
Purpose of the Study:
- To investigate risk factors for surgically treated gallstone disease in a Northern Italian population.
- To identify both risk and protective factors for cholelithiasis.
Main Methods:
- A case-control study design was employed.
- 195 surgical gallstone disease cases and 1122 controls were analyzed.
- Multivariate analysis adjusted for potential confounding factors.
Main Results:
- Increased body mass index (BMI) significantly correlated with higher gallstone risk.
- Higher alcohol consumption showed a protective effect against gallstones.
- For females, increased parity and older age at first birth were associated with elevated risk.
Conclusions:
- Overweight and obesity are identified as significant risk factors for cholelithiasis.
- Alcohol consumption appears to be a protective factor.
- Reproductive factors in women influence gallstone disease risk.
