“…Gallstone prevalence equals to 50% or more among women was found for American Indians in USA,54 and Mapuche Indians in Chile,55 both populations presenting very high GC incidence rates. Other areas reporting high or medium prevalence of gallstones were identified in South America (Chile,55 Argentina,56 Mexico,57 Peru58 and Bolivia59), in Eastern and Western Europe (Austria,60 France,61 Norway,60 Finland,62 the UK,63 Sweden,64 Poland60 and Romania65) and in Australia 66.
