Background: Obesity is the main risk factor for essential hypertension (EH) in childhood. The O.Si.Me. study (Obesity and Metabolic Syndrome in children and adolescents) evaluated the prevalence of metabolic syndrome (MetS) and its constitutive traits in a sample of obese children and adolescents living in Campania, southern Italy. Patients and methods: Four hundred and fifteen children and adolescents consecutively referred to the National Health Service participating Outpatient Clinics for minor health problems and found to have a Body Mass Index (BMI) Z-score > 2.0 were enrolled in the study. The entire sample was screened for MetS, which was defined as the presence of at least 2 of the following alterations in addition to obesity: fasting hyperglycemia, low levels of high-density lipoproteins cholesterol, hypertriglyceridemia, and EH. The present analysis evaluated the clinical characteristics of the O.Si.Me subgroup of EH participants (systolic and/or diastolic BP ≥ 95 th percentile for age, gender and height) as compared with normotensive participants. Results: The prevalence of EH in the O.Si.Me population was 23.6 % (98/415, 48M and 50F.) and two-thirds of the EH participants met the MetS diagnostic criteria. The EH participants featured serum insulin and HOMA-IR levels significantly higher compared with normotensive ones (11.6±0.6 vs. 9.5±0.4 μIU/ml, p = 0.014; 2.6±0.1 vs. 2.2±0.1, p = 0.028 for insulin and HOMA-IR, respectively). These differences were common to boys and girls and remained significant after correction for age, pubertal stage, body weight, length, BMI, gestational age at birth, duration of breastfeeding and anthropometric parental parameters. Accordingly, children and adolescents with EH had a a relative risk of being insulin resistant (defined as a HOMA-IR ≥2.5) significantly greater compared to those without. Moreover, they exhibited higher serum creatinine levels (53.8±7.1 vs. 35.4±6.8 μmol/l, p=0.025) accounting for gender and body weight. Conclusions: More than a quarter of obese children and adolescents meet the diagnostic criteria for EH in the Campania region in southern Italy. These obese boys and girls have an increased prevalence of insulin resistance and apparently an initial reduction in renal function compared with obese children and adolescents with normal BP.

Study Results

BACKGROUND: In the past several decades, the increasing frequency of overweight and obese children and adolescents in the world has become a public health problem. It has contributed significantly to the already high tide of diabetes, cardiovascular and cerebrovascular diseases.AIM: To investigate the frequency of insulin resistance and to evaluate the metabolic profile of insulin resistant and non-insulin resistant obese children and adolescents.SUBJECTS AND METHODS: The study included 96 (45 boys, 51 girls) obese children and adolescents aged     4-17 years old (10.50 ± 2.87 years). Only participants with Body Mass Index ≥ 95 percentile were included.  We analysed sera for fasting insulin levels (FI), fasting serum triglycerides (TG), total serum cholesterol (TC), fasting plasma glucose (FPG) and plasma glucose 2 hours after the performance of the oral glucose tolerance test        (2-h G). Homeostatic model assessment for insulin resistance (HOMA-IR) index was calculated as fasting insulin concentration (microunits per millilitre) x fasting glucose concentration (millimolar)/22.5. The value of HOMA-IR above 3.16 was used as a cut-off value for both genders.RESULTS: Insulin resistance was determined in 58.33% of study participants. Insulin resistant participants had significantly higher level of 2-h G (p = 0.02), FI level (p = 0.000) as well as TG levels (p = 0.01), compared to non-insulin resistant group. Strikingly, 70.73% of the pubertal adolescents were insulin resistant in comparison to 49.09% of the preadolescents (p = 0.03). Significantly higher percentage of insulin-resistant participants were girls (p = 0.009). Moreover, a higher percentage of the girls (70.59%) than boys (44.44%) had HOMA-IR above 3.16 and had elevated FI levels (70.59% vs 48.89%). The difference in the frequency of insulin resistance among obese versus severely obese children and adolescents was not significant (p = 0.73, p > 0.05). Our study results also showed positive, but weak, correlation of HOMA-IR with age, FPG, TG and BMI of the participants (p < 0.05).CONCLUSION: Higher percentage of insulin-resistant participants was of female gender and was adolescents. In general, insulin resistant obese children and adolescents tend to have a worse metabolic profile in comparison to individuals without insulin resistance. It is of note that the highest insulin resistance was also linked with the highest concentrations of triglycerides.

AbstractTo assess the prevalence of metabolic syndrome (MS) in obese children and adolescents in Serbia.The study group consisted of 254 subjects (148 female and 106 male), aged 4.6–18.9 years with diet-induced obesity (body mass index ≥95th percentile). Presence of MS using the International Diabetes Federation definition was assessed in all subjects, as well as oral glucose tolerance test and insulin resistance indices.Overall prevalence of MS in all subjects aged ≥10 years was 31.2%, namely, 28.7% in children aged 10 to <16 years and 40.5% in adolescents ≥16 years. When adjusted for age, gender and pubertal development, higher degree of obesity was a strong predictor of MS. Multivariate analysis showed that taller subjects and those with higher degree of insulin resistance were at significantly higher risk of MS, independent of the degree of obesity.High prevalence of MS emphasizes the need for prevention and treatment of childhood obesity.
