Prevalence of chronic kidney disease in adults with metabolic syndrome

Abstract EN

The burden of chronic kidney disease (CKD) and other non-communicable diseases continues to rise globally, and recent studies suggest that metabolic syndrome (MS) may add to this burden by contributing to the development of CKD.

Given that reports on the prevalence of CKD in patients with MS in this environment are scanty, this study was undertaken with the sole aim of determining the prevalence of CKD in subjects with MS as defined by the International Diabetes Federation (IDF) and the National Cholesterol Education Project Adult Treatment Panel III (NCEP ATP III).

A total of 240 consenting adults (18-70 years) attending the general out-patient clinic of the General Hospital Orica for various ailments were studied.

Subjects were screened for MS as per the above-mentioned criteria.

Estimated GFR (eGFR) was determined with Modification of Diet for Renal Disease (MDRD) formula and CKD was defined as eGFR less than 60 mL/min/1.73 m2.

Data was analyzed using SPSS version 12.0 and Epi info version 4.06d; P <0.05 was considered as significant.

A total of 88 males and 152 females were screened for MS by both criteria.

Eighty-four (35.0%) of 240 subjects had MS as defined by NCEP ATP III, while 85 (35.4%) had MS as defined by the IDF.

The subjects were predominantly females, and mean age was between 54.74 ± 15.30 and 55.60 ± 14.81 years.

Four of the 84 (4.8%) subjects with MS by NCEP ATP III definition had CKD while three of the 85 (3.5%) subjects with MS by IDF definition had CKD.

Among subjects without MS by either definition, the prevalence of CKD was four of 140 (2.9%).

Although the prevalence of CKD was higher among subjects with MS by ATP III compared with those with MS as defined by IDF and subjects without MS, the differences were not statistically significant (X2 = 0.14; P = 0.710).

A comparison of MS subjects without CKD and those with CKD did not show any significant difference in age, waist circumference, body mass index, blood pressure, fasting blood glucose and lipid profile (P > 0.05).

CKD was more common in subjects with MS compared with those without, although the difference was not statistically significant.

The prevalence of CKD in subjects with MS in our study population did not differ significantly when the different MS definitions were employed.
