Question: What is the overall effect of obesity interventions among Korean children and what affects their effectiveness? Finding: Interventions were strongly favored over controls. Interventions including at least one physical activity component were significantly better than those that did not. Sex, age, baseline weight category, intervention duration, and the number of intervention components were not significant. Meaning: Future obesity interventions for Korean children must seek to include physical activity components. |
∙ Because childhood lipid concentrations continue into adulthood, early evaluation and treatment are needed, but dyslipidemia awareness is low. ∙ For the prevention and treatment of dyslipidemia in childhood and adolescence, a major risk factor for cardiovascular disease in adulthood, lifestyle modifications, appropriate exercise, and drug treatment are required. ∙ A large-scale study of the prevalence and therapeutic effects of dyslipidemia in children and adolescents in Korea is needed. |

The risk factors and pathogenesis of developmental dysplasia of the hip (DDH) are unclear. Moreover, no universal screening method can entirely eliminate the risk of DDH. However, its incidence is significant and its early detection is critical for improving patient prognosis. Although the ideal evaluation time and risk factors, especially for premature infants, are unclear, the necessity for DDH screening programs for term and preterm infants is emerging. |
· Evidence shows that patients with type 1 diabetes have been severely affected by coronavirus disease 2019 (COVID-19) in various ways. · Although there is no reliable evidence that COVID-19 worsens or induces diabetes, it can impair β-cell insulin secretion and glucose control by inducing inflammation and cytokine production. · A study is needed of the short- and long-term relationship between diabetes and COVID-19 in the Korean pediatric population. |
