Correlation between metabolic syndrome and colorectal adenomatous polyps in middle- and old-aged patients

AIM: To explore the correlation between metabolic syndrome (MS) and colorectal adenomatous polyps (CAP) in middle- and old-aged patients.

METHODS: The clinical data for 114 middle- and old-aged patients who were hospitalized at our hospital from January 2007 to October 2010 were retrospectively analyzed. They were divided into two groups: patients with CAP (CAP group, n = 64) and those without CAP (control group, n = 50). Blood glucose, blood lipids, blood pressure, body mass, height, and blood uric acid were compared between the two groups. MS was diagnosed according to the criteria proposed by the Chinese Diabetes Society. Univariate and multivariate analyses were performed.

RESULTS: Patients with CAP had significantly higher rates of MS, high blood pressure, abnormal blood glucose and abnormal blood lipids than controls (35.9% vs 8.0%, 67.2% vs 44%, 28.1% vs 6.0%, 48.4% vs 30.0%, all P < 0.05). Although there was no significant difference in body mass index (BMI) between the two groups, the prevalence of high BMI had a tendency to rise in the CAP group (39% vs 24%, P < 0.1). No significant difference was noted in the prevalence of hyperuricemia between the two groups. CAP was significantly correlated with MS and abnormal blood glucose (OR = 4.878, 4.094, both P < 0.05).

CONCLUSION: Patients with MS or diabetes are associated with a higher risk of CAP. MS and abnormal blood glucose may be independent risk factors for CAP in middle- and old-aged patients.
