Abstract

Background It is not known whether, in children and adolescents with alterations in weight and/or blood pressure (BP), lifestyle modifications are associated with an improvement of early cardiac damage.Methods In a pediatric population referred for excess weight, high BP, or both (n = 278, 10.6 (2.3) years), echocardiography was performed at enrollment and after 15 months of follow-up, during which participants received nonpharmacological treatment, based on correcting unhealthy lifestyles and improving dietary habits. Left ventricular mass was indexed for height (g/m(2.7), LVMI), and an LVMI value higher than or equal to age- and gender-specific 95(th) percentile was the criterion for defining left ventricular hypertrophy (LVH). Multiple linear and logistic regression analyses were carried out to determine associations between changes in BMI and BP z-scores and changes of LVMI values and LVH prevalence, from baseline to follow-up.Results At baseline, 33.1% of study participants were hypertensive, 52.9% obese, and 36.3% had LVH. At follow-up, the prevalence of hypertension, obesity, and LVH was 18.7%, 30.2%, and 22.3%, respectively (p < 0.001 for all). A decrease in LVMI from 37.1 to 35.2 g/m(2.7) (p < 0.001) was observed. Only delta BMI z-score positively related to an improvement of LVMI. Reductions of BMI (OR = 0.22, 95% CI 0.07-0.64) and diastolic BP (OR = 0.64, 95% CI 0.42-0.93) z-scores from baseline to follow-up and family history of hypertension (OR = 0.36, 95% CI 0.16-0.78) were associated with a lower prevalence of LVH.Conclusions In a pediatric population at cardiovascular risk, changing incorrect lifestyle and dietary habits is associated with both reduction of BMI and BP values and regression of early cardiac damage.
