title: [Insulin resistance in children].
abstract: Insulin resistance is characterized by decreased tissue sensitivity to insulin. The hallmark of insulin resistance is decreased tissue glucose uptake despite normal or elevated insulin concentration. There has been an upward trend in the incidence of insulin resistance in developed countries, although in pediatric population it is difficult to assess. Both genetic and environmental factors play an important role in the etiology of insulin resistance, namely increased diet caloricity and decreased physical activity. Gradually, this leads to adipose tissue build-up. The role of visceral adipose tissue is of particular importance, mainly due to its significant endocrine activity, leading to adverse metabolic effects. The most important consequences of insulin resistance in children include increased incidence of type 2 diabetes, atherogenic dyslipidemia and arterial hypertension, which lead to increased cardiovascular risk. Children with insulin resistance can develop nonalcoholic steatohepatitis and sleep apnea syndrome. In case of female pediatric patients a higher incidence of polycystic ovary syndrome (PCOS) is observed. Furthermore, the authors reviewed opinions on risk factors for insulin resistance, as well as direct and indirect insulin resistance assessment methods. The article presents the principles of primary and secondary prevention of insulin resistance in children, with particular allowance for dietary recommendations and recommendations to increase physical activity, and, in selected cases, current guidelines on pharmacological treatment.
