Background. Increased carotid intima-media thickness (cIMT) is considered a marker of early-onset atherosclerosis and it seems to predict cardiovascular events both in obese and diabetic subjects. We aimed to evaluate early signs of atherosclerosis and investigate for predisposing factors in children and adolescents affected by type 1 diabetes (T1DM) or obesity, comparing them with healthy controls.

Methods. Out of 71 enrolled subjects (mean age 12.8 ± 2.3 years), 26 had T1DM and 24 were obese, while 21 age- and sex-matched subjects acted as controls. cIMT was measured using standardized methods. Serum glucose, insulin, cholesterol, triglycerides and C-reactive protein levels were evaluated. An oral glucose tolerance test (OGTT) was performed in obese subjects.

Results. Diabetic and obese individuals showed higher cIMT mean values than healthy controls (p<0.005). cIMT of the three examined segments correlated positively with fasting glucose levels and negatively with units of insulin/kg/day administered in T1DM individuals. A positive correlation between insulin levels (basal and after oral glucose load) and cIMT of common, internal and external carotid artery was found in obese subjects (p<0.03). High density cholesterol levels represented a protective factor for cIMT in this latter group of the study population.

Conclusions. Our findings show that cIMT correlates with high insulin levels (a sign of insulin resistance) in obese patients and with high fasting glucose levels (a sign of relative insulin deficiency) in T1DM subjects, confirming the need of reducing hyperinsulinism and monitoring blood glucose levels in these subjects to prevent atherosclerosis.

Keywords: carotid intima-media thickness, atherosclerosis, type 1 diabetes, obesity, children.


Type 1 diabetes (T1DM) and obesity are main risk factors for cardiovascular events [1, 2]. In particular, young adults with T1DM have an increased risk of early asymptomatic atherosclerosis and consequent cardiovascular morbidity and mortality [3-5]. Similarly, childhood obesity has been reported associated with biochemical and inflammatory factors that affect vascular endothelial function and that might confer a premature atherogenicity [6]. Moreover, the insulin resistance, key feature of obesity, metabolic syndrome and type 2 diabetes, results in an array of metabolic and vascular events which finally promote the development of atherosclerosis [7]. The atherosclerotic process starts in childhood and proceeds silently over a long period of time before clinical manifestations [4]. Carotid artery intima-media thickness (cIMT) is considered a significant predictive marker of generalized atherosclerosis because of its correlation with coronary artery disease and it may predict future cardiovascular events in adults [4]. It is also recommended by the American Heart Association as a noninvasive imaging parameter for detecting atherosclerosis [8, 9]. Previous studies reported an increase of cIMT in children with hypercholesterolemia as compared to controls [10]. However, data on this marker in obese children and in children and adolescents with T1DM have yielded conflicting results [11-18].

This study aimed to evaluate the presence of early signs of atherosclerosis and seek for predisposing factors in a group of T1DM children and adolescents treated with intensive insulin protocols and in a group of obese subjects.

Patients and Methods

We enrolled 71 subjects (mean age 12.86 ± 2.38 years) who attended our outpatients Unit of Pediatric Endocrinology. Out of them, 24 were obese (12 males, Body Mass Index -BMI for age and sex >95th centile), 26 subjects had T1DM (12 males, mean HbA1C 8.2 %), with onset of the disease at the age of 2.9 ± 0.2 years, and 21 (11 males, BMI <85th centile) were healthy controls recruited from relatives of our medical staff. All diabetic patients were on treatment with insulin injections 4 times/day, including three meal doses of insulin lispro and one dose of insulin glargine at bedtime. The subjects with clinical, biochemical and instrumental signs of heart disease or family history of hypertension or dyslipidemia were excluded.

A written informed consent was obtained from children's parents or their legal guardians. All the procedures used were in accordance with the guidelines of the Helsinki Declaration on Human Experimentation.

All patients underwent a general clinical examination, anthropometric measurements (height in cm, weight in kg, BMI expressed in kg/m2) using Italian growth charts [19], and assessment of the pubertal and genital stage, according to Tanner criteria [20]. Both systolic (SBP) and diastolic blood pressure (DBP) were measured in all patients [21], while waist circumference was assessed only in obese subjects [22]. Blood glucose, insulin, total cholesterol (TC), high (HDL) and low (LDL) density lipoprotein cholesterol, triglycerides (TG) and C-reactive protein (CRP) were measured after overnight fasting in all subjects; fructosamine and HbA1C were assessed in diabetics. Values of TC, LDL, HDL and TG were considered in the normal range if within the 5th and the 95th percentile [23]. An oral glucose (1.75 g/kg) tolerance test (OGTT) was performed in obese subjects recording basal levels of blood glucose and insulin and after 120 min.

B-mode high resolution ultrasonography (US) was performed with a PHILIPS HDI 5000 Sono CT US scanner, equipped with a linear transducer L 12-5, using a frequency of 18 MHz suitable to study vascular walls. Participants were examined in the supine position with the head turning slightly to both sides. After identifying the bulb, longitudinal images of the common carotid artery and of the two traits that it generates (internal and external carotid) were obtained by combined B-mode imaging and color Doppler. The far wall was scanned and the resolution box was used to magnify this segment, 10-20 mm proximally to the carotid bulb, where were focused all measurements. Several images were acquired by using an anterior oblique angle (30° from midline) and a lateral one (100° from midline) [24]. The cIMT of the far wall was measured during end diastole (R-wave of the electrocardiogram). Three scans on both sides were selected, and nine (3×3) measurements of maximum far wall IMT were averaged; thus, the conclusive mean cIMT of each patient was calculated from a total of 18 measurements.

We defined the cIMT as thickened when ≥ 0.45 mm in children younger than 10 years or if it was ≥ 0.55 mm in children older than 10 years and younger than 18 years [25-28].

Statistical analysis

Statistical analysis was performed using SPSS Software for Windows (version 15, Chicago, IL, USA). Data are expressed as means, standard deviations and percentages. Comparisons between groups or within the same group were made using the Kruskal-Wallis and the Wilcoxon-Mann-Whitney U non parametric tests, respectively. Spearman rho correlation analysis and multiple regression models were used to include cardiovascular risk factors. A p value <0.05 was considered statistically significant.


Clinical features of the study population are shown in Table 1.

Age, height and stage of pubertal development did not differ significantly within the three studied groups, while, as expected, obese subjects had increased weight and BMI values compared to T1DM patients and controls. SBP and DBP were higher in obese and diabetics than in healthy subjects (p<0.015 and p<0.002, respectively). A positive correlation between SBP and BMI was found in obese individuals (rho=0.26; p<0.02) (data not shown).

Among T1DM patients, 77% of them had blood glucose concentration greater than 180 mg/dl, 54% had HbA1C greater or equal to 8%, and 73% had fructosamine levels greater than 300 µmol/L; TC, HDL, LDL cholesterol, TG and CRP values were in the normal range. The levels of LDL cholesterol and TG were increased in 4.2% and 12.5% of the obese subjects, respectively. Their TG values were significantly higher compared to both diabetics and controls (p<0.001). All obese patients had normal glucose tolerance with basal hyperinsulinemia (32.2 ± 14.2 μU/ml) and after glucose loading (141.2 ± 56.54 μU/ml).

cIMT values resulted higher in obese subjects than in diabetics (p<0.05), and in both these groups compared to controls (p<0.007 and p<0.02, respectively) (Fig.1). Diabetic subjects showed a positive correlation between cIMT of the three studied segments and fasting blood glucose levels (rho=0.47, p<0.05). cIMT tended also to be negatively correlated with the units/kg/day of insulin administered in the same group of subjects (rho=-0.29, p=0.05). The mean cIMT values were also significantly higher among diabetic boys than age-matched healthy control subjects (0.51 ± 0.05 vs 0.49 ± 0.05; p<0.02). No association between cIMT and age of diabetes onset was observed in this study.

We found a positive correlation between insulin levels (basal and after oral glucose load) and cIMT of common, internal and external carotid artery in the obese (rho=0.47, p<0.03). Furthermore, the obese boys had higher mean cIMT value than girls (0.52 ± 0.03 vs 0.51 ± 0.04; p<0.05) and the mean cIMT was significantly higher among obese boys than age-matched healthy control subjects (0.52 ± 0.03 vs 0.46 ± 0.05; p<0.01), but not among obese girls. cIMT values were also higher in subjects during puberty than at the prepubertal age (T1DM vs obese vs controls: 0.51 ± 0.05 vs 0.52 ± 0.04 vs 0.46 ± 0.05; p<0.005). The overall measurement of cIMT was also significantly different within studied groups stratifying the analysis by height: individuals less than 150cm of height had higher values of c-IMT, compared to controls, than taller subjects (0.53 ± 0.03 vs 0.52 ± 0.04 vs 0.47 ± 0.05; p<0.04). Figure 2 shows the distribution of c-IMT values within the study groups in pubertal age males with height less than 150 cm (0.52 ± 0.02 vs 0.51 ± 0.05 vs 0.46 ± 0.03; p<0.02).

The multiple regression analysis performed in the obese group, selecting SBP, DBP, TC, HDL and TG as independent variables and cIMT as the dependent variable, showed that HDL cholesterol represented a protective factor for the thickening of cIMT (OR=0.58 with a 95% confidence interval of 0.31-0.73, p=0.04), while the other analyzed parameters did not seem to affect cIMT in this group of subjects.

In this study we identified subclinical atherosclerosis in T1DM patients and obese subjects as indicated by their significantly higher cIMT (mainly in boys) compared to that of healthy controls. Our results suggest that the common pathogenetic factor involved in endothelial damage in obese and T1DM children and adolescents seems to be a reduced insulin function (insulin deficiency in diabetics and insulin resistance in obese patients, respectively). Insulin acts by modulating the release of vasodilator substances, such as nitric oxide and prostaglandins, from vascular endothelium, by both stimulating and inhibiting the sympathetic nervous system and by protecting smooth muscle cells in blood vessel from apoptosis induced by oxidative stress [29]. Thus the vasodilatory and antioxidant effects of insulin are depressed in case of insulin deficiency (i.e. type 1 diabetes) and insulin resistance (i.e. obesity) conditions.

It is well documented that cIMT correlates with coronary atherosclerosis [4], and that it represents an independent predictor of future cardiovascular events [9]. It also well correlates with parameters of invasive examination tools, such as coronary angiography and intravascular ultrasound [4, 30].

Studies on increased cIMT in children and adolescents affected with obesity, T1DM, dyslipidemia, hypertension and chronic renal failure, compared to healthy controls, have yielded conflicting results [31, 32]. The different conclusions may be explained by the non-homogenous populations studied and by the variety of ultrasound methods used. Although in our study obese individuals showed only slightly elevated mean cIMT compared to subjects with T1DM, a significant high number of diabetic and obese patients had cIMT above the normal range, indicating that these patients showed early signs of atherosclerosis development compared with healthy controls.

The degree and duration of hyperglycemia has been associated with macrovascular complications and increased cardiovascular risk in adults and preadolescent children with T1DM [5, 33-36]. In the present study no association between cIMT and HbA1C at the time of visit (a marker of glycemic control) was observed in diabetic subjects. However, the positive correlation between cIMT (especially of the left common carotid intima) and fasting blood glucose suggests that accumulation of glycation end products, as a consequence of not optimal insulin therapy, increases oxidative stress and the subsequent cell damage. This hypothesis is also confirmed by the negative correlation, even if not statistically significant, between the values of cIMT and the units of insulin daily administered. In obese individuals, the positive correlation between basal and after oral glucose load insulin levels and cIMT shows that insulin resistance causes an imbalance of vascular homeostasis mechanisms responsible for the endothelial damage and dysfunction [29, 37].

Previous studies have shown that cIMT is negatively correlated with HDL cholesterol levels and positively related with LDL levels, confirming that dyslipidemia has a prominent role in the pathogenesis of endothelial dysfunction with progression to atherosclerosis [6, 38, 39]. In line with data reported in literature, HDL cholesterol values represent a protective factor for cIMT in our obese population. On the other hand, although increased cIMT has been documented in children with daytime hypertension, as well as in those with nocturnal hypertension and T1DM [25, 40], in our study population no association between conventional cardiovascular risk factors, such as blood pressure or LDL cholesterol and cIMT was found. This could be explained by the short duration of the disease at the time of examination, and the young age of the study population.

The gender-related difference in cIMT measurements observed in our study (higher prevalence of atherosclerosis and cardiovascular disease among males compared to females) is in line with data reported in literature on the general population of children and adolescents [33, 34]. Furthermore, our obese subjects showed a higher value of cIMT during puberty than that recorded in those at the prepubertal age. This could be explained by the change of insulin sensitivity for increased activity of the growth hormone axis (GH)-IGF1, which worsens the condition of insulin resistance during puberty. Furthermore, recently Skilton and colleagues have positively correlated cIMT with height in non-diabetic children aged 8-years [41], while in this study we have observed that diabetic children with high risk for increased cIMT are likely males at pubertal age less than 150 cm tall (Figure 2). Additional study in selected groups of children should be carried-out to get more conclusive results.

In conclusion, we found that diabetic and obese children present (as adults) an endothelial damage, confirmed by increased cIMT values. Our results point out the importance of identifying children with the highest risk for cardiovascular heart disease using noninvasive studies, even if more studies on wider populations are warranted to confirm the findings. We also observed that there is a positive correlation between high levels of basal and after oral loading glucose insulin levels (a sign of insulin resistance) and increased cIMT in obese, as well as between high fasting blood glucose levels (a sign of relative insulin deficiency) and cIMT in T1DM patients. Thus it is necessary to normalize blood glucose values by optimizing insulin therapy in diabetic subjects, and to reduce hyperinsulinism by weight loss and physical activity in obese subjects, in order to prevent future cardiovascular risks.
