Updated epidemiologic study of urolithiasis in Turkey II: role of metabolic syndrome components on urolithiasis.
The components of metabolic syndrome, such as obesity, hypertension, and diabetes, are thought to be associated with urolithiasis. However, there are few large-scale studies that have examined the association between metabolic syndrome and urolithiasis, which prompted us to study and evaluate the relationship between metabolic syndrome components and urolithiasis in a nationwide survey, using the cross-sectional study conducted by a professional investigation company, with 2,468 enrolled participants, aged between 18 and 70 years, from 33 provinces in Turkey. Participants were interviewed face-to-face by medical faculty students. Participants with a history of urolithiasis (Group 1) were compared with participants without a history of urolithiasis (Group 2) in terms of hypertension, diabetes, body-mass index (BMI), waist size, and trouser size using Chi-square and odds ratio tests. Of the 2,468 participants, 274 (11.1%) reported a history of urinary stone disease diagnosed by a physician. The percentage of participants with hypertension along with urolithiasis was significantly higher than that in participants without urolithiasis (16.9 and 34.3%, p 0.000, OR 3.0). The percentage of participants with diabetes in groups 1 and 2 was 14.2 and 9%, respectively (p 0.001, OR 1.83). The mean BMI was 27.2 and 25.2, respectively (p 0.01). Participants with a BMI >30 had a 2.2-fold increased risk of having urolithiasis. The mean waist size was significantly greater in participants with urolithiasis (p 0.000). Those with a waist size >100 cm had a 1.87-fold increased risk of having urolithiasis. The mean trouser size was also significantly larger in those participants who were stone formers (p 0.003). The results indicate that metabolic syndrome components are important factors in the development of urolithiasis.
