Childhood adiposity: being male is a potential cardiovascular risk factor

As the earliest atherosclerotic lesions begin during childhood, our aim was to correlate gender-related adiposity to classical cardiovascular risk factors in a group of children.An observational and transversal analysis was carried out in a cohort consisting of 161 children of both sexes, aged 6 to 17 years of age. Waist circumference was correlated to leptin, high-sensitivity C-reactive protein, systolic and diastolic blood pressure, plasma lipids, homeostasis model assessment-insulin resistance, and the left ventricular mass index. After adjusting for age, waist circumference in boys, compared to girls, correlated more strongly and directly to systolic (r = 0.538; p < 0.001) and diastolic blood pressure (ρ = 0.401; p < 0.01), ApoB/ApoA ratio (ρ = 0.515; p < 0.01), high-density lipoprotein cholesterol (r = −0.441; p < 0.001), low-density lipoprotein cholesterol (ρ = 0.280; p < 0.01), triglycerides (ρ = 0.420; p < 0.001), homeostasis model assessment-insulin resistance (ρ = 0.463; p < 0.001), and the left ventricular mass index (ρ = 0.286; p < 0.01). A similar pattern was observed regarding the correlations between leptin, high-sensitivity C-reactive protein, and the above parameters (except between high-sensitivity C-reactive protein and diastolic blood pressure), and also, particularly in boys.
