title: [Study on the epidemiology and risk factors of renal calculi in special economic zone of Shenzhen city].
abstract: OBJECTIVE
  To study the epidemiological characters and risk factors of renal calculi in Shenzhen for future intervention.
  
  
  METHODS
  Risk factors of renal calculi were analyzed by factor analysis and linear structural relation model, followed by fitting and evaluating the model.
  
  
  RESULTS
  The prevalence rates of renal calculi were 8.00% and 5.12% in males and females. The results of LISEREL showed that the total effect of age and sex affecting the development of renal calculi was 0.4614, with directly effect 0.3600 and indirect 0.1014. The direct effects of blood uric acid, blood calcium and body mass index, blood cholesterol, blood sugar were 0.3400 and 0.3200 respectively. The indirect effect of education, exercise and dietary habit affected the development of renal calculi through index of biochemistry and obesity, were -0.0416 and 0.1882.
  
  
  CONCLUSIONS
  Sex, age, obesity and high blood cholesterol, high blood sugar, high blood uric acid, high blood calcium were the direct influencing factors to renal calculi. At the same time, education, exercise and dietary habit were also associated with the disease.
