Background: Definitions of childhood and adolescent hypertension (HTN) do not precisely elucidate the relationship between HTN and cardiovascular outcomes. Carotid intima-media thickness (CIMT), as a substitute for cardiovascular outcomes, enables the early identification of cardiovascular events throughout early adulthood.
Purpose: This study aimed to compare the ability of childhood HTN definitions to predict a high CIMT in early adulthood. Methods:... |
Background: Exclusive breastfeeding (EBF) provides numerous health benefits to children. However, the EBF rate is unsatisfactory among young mothers because they often experience difficulties. Thus, interventions during the postnatal period are imperative to encouraging EBF practices in these populations. Postnatal care (PNC) should be delivered appropriately to ensure a positive postnatal experience; however, there has been little discussion of evidence... |
· We suggest offering long-term macrolides to children with noncystic fibrosis bronchiectasis with frequent exacerbations (conditional recommendation, moderate quality of evidence). · We do not recommend the routine use of mucolytic agents, inhaled corticosteroids, or nonsteroidal anti-inflammatory drugs to prevent exacerbation of bronchiectasis in children (inconclusive, very low quality of evidence). · We recommend the use of nebulized hypertonic saline to prevent exacerbations and improve the lung function of children with noncystic fibrosis bronchiectasis (weak recommendation, moderate quality of evidence). |
· Dietary macronutrient modifications affect the body composition of and metabolic markers in children and adolescents. · Hypocaloric diets, regardless of macronutrient composition, are reportedly effective for weight loss in obese children. · Future interventional studies with meta-analyses that include Korean children and adolescents are needed to provide basic information applicable to this population. |
In Korea, several national cross-sectional surveys monitor the diet, nutritional status, and health status of children. This continual dedicated national surveillance system contributes to the identification of nutritional and health issues, establishment of public health policies, and development of nutrition recommendations. This paper provides recent information about the Korea National Health and Nutrition Examination Survey and the Korean Youth Risk... |
Atrioventricular nodal reentry tachycardia (AVNRT) is less common in pediatric patients than in adult patients. Thus, data for pediatric AVNRT patients are insufficient. Hence, we aimed to analyze the patient characteristics, treatment, and any recurrences in pediatric AVNRT patients. We reviewed the records of 50 pediatric AVNRT patients who had undergone radiofrequency catheter ablation (RFCA) between January 1998 and December 2016... |
Severe aplastic anemia (SAA) is a life-threatening disorder for which allogeneic hematopoietic stem cell transplantation (HSCT) is the current available curative treatment. HSCT from matched sibling donors (MSDs) is the preferred therapy for children with acquired SAA. For patients who lack MSDs, immunosuppressive therapy (IST) is widely accepted as a first-line treatment before considering HCT from an unrelated donor (URD).... |
Osteosarcoma is the most frequent primary bone tumor. Advances in combination chemotherapy and surgical technique have greatly improved the survival of patients with osteosarcoma. In Korea, improvements in osteosarcoma treatment have been made over the past two decades. The 5-year event-free survival rate of Korean children and adolescents with localized disease is 64.6%, comparable to that of American or European... |

However, data on the normal CPET values for Korean children and adolescents are lacking. The aim of this study was to provide reference data for CPET variables in children and adolescents. From August 2006 to... |
During the adolescent period, they experience rapid physical, emotional, cognitive developments while they establish their lifestyle and habitual routines that strongly influence adult health and life. Recent rapid economic growth in Korea, and the earlier onset of physical, sexual, and psychological maturation of adolescents, has resulted in changes in the health status of adolescents from many years ago. Risk-taking behaviors... |
Increasing numbers of children and adolescents prefer undertaking physical exercise to overcome overweight or obesity. Children and adolescents are in the growth stage and require adequate nutrient supply. More calories and nutrients are required especially when they are engaged in physical exercise. Exercise is the only means to increase lean body mass and decrease body fat, but adequate nutrient supply... |
Childhood obesity has rapidly increased in Korea during the past 20–30 years. Approximately 1 of 10 children and adolescents is obese. Appropriate prevention and intervention measures urgently need. Obesity prevention starts early in life, i.e., obesity prevention and education begins during the period of fetal development in utero. Behavioral changes are the most positively reflected during pregnancy. Infants should be... |
Vitamin D is an important fat-soluble vitamin that functions as a prohormone and affects bone mineralization and calcium homeostasis. Vitamin D deficiency causesboth musculoskeletal manifestations, including rickets, and extra-musculoskeletal symptoms. Because vitamin D is naturally present in only some foods, intake of daily foods cannot meet the dietary reference intake for vitamin D. Sunlight is the main source of vitamin... |

Purpose : Obesity is associated with insulin resistance. Insulin resistance and the presence of pro-inflammatory mediators are thought to cause a state of vascular endothelial dysfunction, an abnormal lipid profile, hypertension, and vascular inflammation. These chronic inflammatory responses, which are characterized by abnormal cytokine production, lead to activation of a pro-inflammatory signaling pathway. Leptin is an important mediator of inflammatory... |
Type 1 diabetes mellitus (T1DM) develops in genetically susceptible individuals as a result of progressive autoimmune destruction of beta cells. There is a large global variation in incidence among children aged 0-14 years. The incidence of T1DM in Korea is very low. The latest survey in Korea was conducted in 2001 by the Korean Society of Pediatrics to analyze ... |
The prevalence of obesity in Korean children is estimated to be around 10%, and has increased significantly over the past 20 years. Metabolic syndrome, which includes central obesity, glucose intolerance, insulin resistance, dyslipidemia, and hypertension, is a well documented risk factor for cardiovascular diseases, but there is no general consensus concerning its definition for children. In this study, ablut 30-40%... |
Since the tuberculosis (TB) in adolescents has unique clinical characteristics, special attention should be paid to this age group. Adolescents are more susceptible to developing TB disease and more likely to have cavitary pulmonary disease. Also, adolescent patients with TB more frequently present with extrapulmonary disease. We report three adolescents with active pulmonary and/or intestinal TB: one had pulmonary and... |
Purpose : Pulse wave velocity(PWV) and ankle brachial index(ABI) are not only noninvasive methods used to assess arterial stiffness in adults, but also useful, simple ways to estimate the severity of hypertension, end stage renal disease and atherosclerosis in adults. But there are few studies on PWV and ABI in adolescents and children. In this study, hypertensive adolescents were compared... |
Headaches are common in children and become more common and increase in frequency during adolescence. There are various causes of headaches. The majority of cases are considered as primary and include migraine and tension headaches. The rational evaluation of headache begins with careful history.
