  1. Gallstone disease in high-altitude Peruvian rural populations.

    Article - En anglais

    Objective 

    Cholelithiasis is a common problem in hospitals of the Peruvian Andes ; however, its prevalence in Andean communities is unknown.

    To estimate the prevalence of gallstone disease in this locale, we conducted a cross-sectional community study in three high-altitude Peruvian rural villages (i.e.,>3000 m above sea level).

    Methods 

    We examined 911 volunteers>15 yr of age from three villages for gallstone disease by history and ultrasonography.

    Risk factors for gallstone disease were examined in 382 volunteers from one village.

    Results 

    The age-adjusted prevalence of gallstone disease ranged from 4-10% in men and from 18-20% in women.

    Women had significantly higher age-adjusted prevalence rates than did men.

    The prevalence of gallstone disease increased significantly with age and decreased significantly with alcohol consumption.

    Although not statistically significant, we found a positive association between gallstone disease and body mass index.

    Conclusion 

    The results of this study indicate that gallstone disease, commonly perceived as a disease of the developed world, is also a common problem in high-altitude Peruvian communities.
