Summary

Updated gallstone disease risk factors include higher body mass index, parity greater than two, breast-feeding, oral contraceptive use, and family history. Age and female sex were not significant risk factors in this study.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Epidemiology

Background:

  • Established risk factors for gallstone disease require updated evaluation.
  • Advancements in ultrasound technology and laparoscopic surgery necessitate re-examination of risk factors.
  • Understanding current risk factors is crucial for disease prevention and management.

Purpose of the Study:

  • To identify and validate contemporary risk factors for gallstone disease.
  • To compare risk factor prevalence between patients with and without gallstones.
  • To assess the influence of modern medical advancements on gallstone disease etiology.

Main Methods:

  • A comparative study involving two groups: gallstone patients (n=100) and a control group (n=107).
  • Ultrasound was used to diagnose gallstones.

  • Patient data including body mass index, parity, breast-feeding history, oral contraceptive use, and family history were collected and analyzed.

    • Main Results:

    • Significant risk factors identified: higher body mass index (p=0.013), parity > 2 (p=0.000001), breast-feeding (p=0.03), oral contraceptive use (p=0.0005), and family history of gallbladder surgery (p=0.02).
    • Age and female sex were not found to be significant risk factors, potentially due to selection bias.
    • The surgery group exhibited higher prevalence in all identified risk factors compared to the control group.

    Conclusions:

    • Body mass index, parity > 2, breast-feeding, oral contraceptive use, and family history are confirmed as significant risk factors for gallstone disease.
    • Age and female sex may not be independent risk factors, likely influenced by study selection bias.
    • These findings provide an updated understanding of gallstone disease etiology, relevant for clinical practice and public health initiatives.
