ABSTRACT
Objectives. To investigate whether lifestyle-only intervention in obese children who maintain or lose a modest amount of weight redistributes parameters of body composition and reverses metabolic abnormalities. Study Design. Clinical, anthropometric, and metabolic parameters were assessed in 111 overweight or obese children (CA of 11.3 ± 2.8 years; 63 females and 48 males), during 8 months of lifestyle intervention. Patients maintained or lost weight (1–5%) (group A; n: 72) or gained weight (group B). Results. Group A patients presented with a decrease in systolic blood pressure (SBP) and diastolic blood pressure (DBP) ( and , resp.), BMI ( ), z-score BMI ( ), waist circumference ( ), fat mass ( ), LDL-C ( ), Tg/HDL-C ratio ( ), fasting and postprandial insulin ( ), and HOMA ( ), while HDL-C ( ) and QUICKI increased ( ). Conversely, group B patients had an increase in BMI ( ), waist circumference ( ), SBP ( ), and in QUICKI ( ), while fat mass ( ), fasting insulin ( ), and HOMA ( ) decreased. Lean mass, DBP, lipid concentrations, fasting and postprandial glucose, postprandial insulin, and ultrasensitive C-reactive protein (CRP) remained stable. Conclusions. Obese children who maintain or lose a modest amount of weight following lifestyle-only intervention tend to redistribute their body fat, decrease blood pressure and lipid levels, and to improve parameters of insulin sensitivity.
