title: [Prevalence of cholelithiasis in El Real-Gandia].
abstract: The aim of this study was to know the prevalence of cholelithiasis (C) in the El Real-Gandia (Spain) as well as the degree of the response of the population. Health examinations were performed in 1,803 adults from El Real (2,000 inhabitants) and Gandia (54,000 inhabitants) using abdominal echography as the screening technique. Cholelithiasis was defined as the presence of biliary lithiasis (BL) or previous cholecystectomy (PC). Of 1,268 (70.3%) participants in the study, C was found in 126 cases (BL in 102 and P in 24) representing a standardized prevalence of around 15% in women and 5% in men. Cholelithiasis was more frequent in females (13.8%) than in males (5.7%) (p < 0.001) increasing linearly with age (p < 0.005). The proportion of PC was significantly higher in women (23.9%) than in men (5.9%) (p < 0.05) and in Gandia (34.4%) than in El Real (13.8%) (p < 0.02). The prevalence of biliary mud and polyps was of 0.3% and 1.1%, respectively. Working obligations (35.4%) and fear of hospitals (22.4%) were the most frequent causes for no response (NR). Males with more than primary a school education originating from outside the Valencian community (VC) were significantly associated with NR in multivariant analysis.
