Abstract
OBJECTIVES: Carotid intima-media thickness (CIMT) is a surrogate marker of subclinical atherosclerosis and a
predictor of cardiovascular events. Few studies in Africa have evaluated CIMT and its associations in people with
type 2 diabetes mellitus. This study measured CIMT in a sample of mainly black South African patients with type 2
diabetes mellitus, and evaluated the association of demographic and clinical risk factors with CIMT.
DESIGN: Cross-sectional study.
SETTING: Kafalong Hospital, a large community hospital in Pretoria that mainly serves an urban black community.
SUBJECTS: Patients with type 2 diabetes mellitus.
OUTCOME MEASURES: We evaluated clinical, biochemical and CIMT ultrasound measurements in a standardised
fashion.
RESULTS: In 185 patients, the univariate significant predictors of mean far-wall CIMT were age [beta 0.007 (standard
error 0.001)], systolic blood pressure [beta 0.001 (standard error 0.000)] and inverse serum creatinine [beta -8.15
(standard error 3.23)]. Low-density lipoprotein cholesterol, apolipoprotein A-1, apolipoprotein B:A-1 ratio and
apolipoprotein B:A-1 ratio > 1.2 all had p-values below 0.1, but above 0.05. Age had the largest R-squared (20%).
The multivariate models did not explain more of the variation in CIMT than did age alone.
CONCLUSION: Lipid parameters were related to CIMT in our study population. However, this did not reach statistical
significance in this relatively small sample, and lipids added very little to the variability of CIMT compared with age
alone.
