[Food consumption patterns and risk of gallstone disease (GD): Case and Control Study in Rosario Argentina.].

Introduction: Nutritional exposure is considered the main environmental influence that contributes to gallstone disease (GD).

Aim: The aim of this study was to determine food intakes patters and estimate risk of GD.

Methods: A nested case-control study was carried out within the framework of a previous screening study conducted on a representative sample in Rosario, Argentina.

A nested case-control study on dietary fat consumption and the risk for gallstone disease.

Background: Gallstone disease (GD) incidence and prevalence rates differ between populations. Diet and lifestyle may be involved in GD development. To our knowledge, no study to date has evaluated quantitative data on diet when studying the relationship between fat consumption levels and GD in an Argentinean population.

[Food intake pattern in a sample of adults with gallbladder disease (GD)].

In Rosario, Argentina, a 20,5% prevalence rate of Gallbladder Disease (GD) was found in a random sample of adults. The aim of this study was to determine the food consumption pattern of subjects with GD nested in that sample for further comparison with the Recommended Dietary Allowances (RDA). Forty-four subjects were interviewed about the food consumption during the five years before their diagnosis, by applying a semi-quantitative food frequency questionnaire (FFQ) and a photographic atlas of standardized portions.

Morphological and demographic associations of biliary symptoms in subjects with gallstones: findings from a population-based survey in Rosario, Argentina.

Background: Gallstone disease is a frequently encountered disorder in subjects living in Rosario. The reasons for the presence or absence of symptoms are unknown.

Aims: To determine associations between biliary symptoms and ultrasonographic features of gallbladder and gallstones.

Epidemiology of gallstone disease in Argentina: prevalences in the general population and European descendants.

To assess gallstone disease prevalence in Argentina, a random sample of the Rosario City population was studied, considering already known associated factors, and analyzing ethnic groups living in the city. A total of 1,173 participants (69% response), both sexes, 20 years and older were studied. Each subject underwent an abdominal ultrasound examination, a blood test, and a standardized questionnaire.
