Risk factors of subclinical atherosclerosis in obesity and overweight

To examine the relationship of carotid intima-media thickness with weight-gain, overweight and obesity..

The experimental, analytical study was conducted at the CF University Hospital, Cluj-Napoca, Romania, from 2012 to 2014, and comprised randomly selected in patients from the Medical Ward. The patients were divided into normal-weight subjects in Group I and overweight and obese subjects in Group II Intimate-media thickness was measured by carotid Doppler ultrasound. Data was analysed using SPSS 13.

Of the 111 subjects, Group I had 27(%) and Group II had 84(%) subjects. Mean carotid intimamedia thickness was significantly greater (p<0.001) in Group II compared to Group I, especially in those with metabolic syndrome (p<0.001) and higher high-sensitivity C reactive protein (p<0.05). With the exception of Group II where there was a direct correlation (p<0.05) between triglycerides and intimamedia thickness, and an inverse correlation (p<0.05) between high-density lipoprotein and intimamedia thickness, no significant correlations were recorded (p>0.05).

Intima-media thickness was found to be increased in asymptomatic overweight and obese subjects, significantly higher in those with associated metabolic syndrome and high levels of highsensitivity C-reactive protein, as an indication of the presence of early, subclinical atherosclerosis.
