[Study on the prevalence of metabolic syndrome among diabetic population]

To observe the prevalence of metabolic syndrome (MS) among people with diabetes.

9 275 diabetic patients (FPG was ≥7.0 mmol/L or FPG < 7.0 mmol/L but diagnosed as diabetes or having history of diabetes, or were under hypoglycemic agents treatment) of 101 510 employees of Kailuan group who took physical check-up between 2006 and 2007, were recruited to take part in this study. Using the latest defined diagnostic criteria on MS from the 2010 hypertension guidelines, prevalence of MS among the population was analyzed, according to age and gender. Multiple logistic regression analysis was used to test the relevant factors of MS.

There were 6 105 cases with MS among the population with the prevalence as 65.8% (female:70.0%, male:64.9%). Stratified by age and gender, the prevalence rates of MS among young-age group, middle-age group and elderly group were 59.7%, 66.0% and 68.8%, respectively. The prevalence in males among the three groups was 61.4%, 64.9% and 67.0% , respectively. The prevalence rates in females among the three groups were 50.3%, 70.7% and 78.8%, respectively. Stratified by age and gender, the prevalence of waist abnormal in female was the highest (100.0%) in the youth group that with MS. However, the prevalence of dyslipidemia appeared the highest (86.3%) in males. In the elderly group with MS, the prevalence of abnormal blood pressure was the highest in both males and females, up to 96.0%. Results from multi-factor logistic regression analysis showed that cigarette smoking would increase the risk of developing MS in the youth group (OR = 1.89, 95%CI:1.09-3.28) and the risk of developing MS of man was lower than women in the middle-aged group (OR = 0.77, 95% CI:0.67-0.89; OR = 0.48, 95% CI:0.35-0.66).

In the diabetic population, MS prevalence in female appeared to be higher than in males. The prevalence of MS tended to increase with age. Cigarette smoking could increase the risk of MS in the youth group.
