Abstract:
OBJECTIVETo determine the risk factors of urinary calculi in Shenzhen for proper interventions.
METHODSA population-based case-control study including 334 urinary calculi cases and 721 controls was carried out. A total number of 34 factors were analyzed using unconditional logistic regression.
RESULTSSeventeen factors were associated with urolithiasis based on the logistic regression analysis. Ten factors entered the last model of the logistic multivariate regression. The more protein consumption (OR = 2.14, 95% CI: 1.71 - 2.69), positive history of first relatives with urolithiasis (OR = 2.61, 95% CI: 1.70 - 4.01), longer outdoor exposure (OR = 1.39, 95% CI: 1.16 - 1.66) and chronic inflammation of urinary system (OR = 4.09, 95% CI: 1.38 - 12.14) were risk factors of urinary calculi. Higher education background (OR = 0.46, 95% CI: 0.29 - 0.73), drinking more water (OR = 0.59, 95% CI: 0.48 - 0.72), drinking more juice (OR = 0.41, 95% CI: 0.18 - 0.94), more milk and milk product consumption (OR = 0.82, 95% CI: 0.68 - 0.99), vegetable (OR = 0.70, 95% CI: 0.55 - 0.91) and fruit consumption (OR = 0.78, 95% CI: 0.64 - 0.94) were protective factors of urolithiasis.
CONCLUSIONDietary habits were the major influencing factors of urinary calculi. Positive history of family with urolithiasis and social-economic factors were also associated with the disease.
