A Case-Control Study On Urinary Calculi And Dietary Factors

Research background: Urolthiasis is one of uninary system common diseases, isone kindis complex, the multi- causes of disease disease, is factorcombinedaction the and so on geographical environment, diet custom as wellasheredity background result. Anderson to the global 11 different areas and thenational mealsstructure investigations, thought the diet structure is a baselinewhich in any society the stone recurs, other factors are playing in thisfoundation the promotion or the suppression role. Good sends to 30～50 year-oldyoung adults crowd. The western nation formation rate 500 examples/100,000 people,our country formationrate is 101 examples/100,000 people, in recent years theformationrate assumed the trend of escalation. Although in extracorporeal shockwave lithotripsy(ESWL), the surgical operation and so on the many kinds of methodsmay treat the urolthiasis, but it recurring rate is high (in for 2-7 yearrecurringrate is in 22.6％-51％,10 years is 80％). The people since thought themodern times the social nutritions tructure change has been the main reason whichthe urolthiasis incidence rate and recurring rate elevates. But in the uropoiesisis in stone pathogenesis many factors, many are the natural environment factorwhich the people at present with difficulty controls, like climate, sunshine,water quality, sex, hereditary feature and so on; But the suitable adjustment dietstructure and the habits and customs quite are on the other hand easy to achieve.Objective: Through the epidemiology research, discovers each kind of diet thedangerous factor, the dangerous factor which the exploration urotthiasis arises,prevents for the crowd provides the preliminary basis.Methods: Selects the Guangdong Province traditional Chinese medicine hospitalin March, 2006-December, 2006 in extracorporeal shock wave lithotripsy center159 examples patients same time to be hospitalized for case of illnessgroup,,141in this courtyard surgery in urology department the non-stone patient is the comparison group, uses compares the research based on hospital urolthiasis dietdangerous factor crowd Case control study. The concrete method is uses theself-made examination table by the special investigator to inquire investigationobject for year each kind of liquid daily takes in the situation, each kind ofhost, the nonstaple food usually takes in the situation, and inquires it usuallymeals taste, as well as family main cooking oil type. Uses the unconditionlogistic regression to carry on the analysis to 16 variables, and the unionspecialized knowledge gives the analysis.Results:Urolthiasis case of illness group and the comparison group allocatedproportion condition is balanced may compare. In Sixteen factors thirteen wereassociated with urolithiasis based on the uncondition logistic regressionanalysis, finally six factors entered the last model of the uncondition logisticmultivariate regression. They may incorporate into three kinds, namely thepotable water, the diet custom, the nutrient take in. Frequently drinks thenutritious soup(OR=3.61, 1.70～4.01), more intake of animal protein(OR=1.73,1.71～2.69) were risk factors of urinary calculi, frequently drinks the fruitjuice(OR=0.31, 0.18～0.94), drinks the weak tea(OR=0.46, 0.29～0.73),frequently drinks the dairy products (OR=0.69, 0.68～0.99), drinking more waterdaily (OR=0.67, 0.64～0.94)were protective factors of urolithiasis.Conclusion: Results indicated that dietary and nutritional factors wereimportant risk actors to the etiology of urinary calculi.
