Development of the Korean Global Physical Activity Questionnaire: reliability and validity study.

The goal of this study was to develop a Korean version of the Global Physical Activity Questionnaire (K-GPAQ) and to examine its reliability and validity. The English version of the GPAQ was translated to the Korean language (K-GPAQ) via forward-backward translation. Reliability of the K-GPAQ was evaluated using a one-week interval test-retest method with 115 individuals.

The effect of predominant breast-feeding on the risk of obesity in Korean preschool children.

The purpose of this study was to investigate the prevalence of predominant breast-feeding practices based on the criteria given by the World Health Organization and to identify the association between predominant breast-feeding during infancy and the development of obesity during preschool in South Korean children. This study employed a nonexperimental, retrospective study design. Five hundred and twenty-eight preschool children aged three to six years and their mothers were recruited.

Reduced serum total osteocalcin is associated with central obesity in Korean children.

Background: Recently, osteocalcin (OC), an osteoblast-derived hormone, has been suggested as a new link between obesity and insulin resistance in humans. However, few studies regarding the relationship between OC and obesity in Asian children have been published. We investigated the association of OC with adiposity, insulin resistance and metabolic syndrome (MetS) in Korean children.

Low levels of physical activity are associated with increased metabolic syndrome risk factors in korean adults.

Background: Low levels of physical activity (PA) are strongly associated with the development of metabolic syndrome (MetS) and chronic diseases. However, few studies have examined this association in Koreans. The primary purpose of this study was to examine the associations between PA and MetS risks in Korean adults.

The association of adolescent fatness and fitness with risk factors for adult metabolic syndrome: a 22-year follow-up study.

Background: Few studies have been conducted to explore the associations of fatness and fitness during adolescence with risk factors of metabolic syndrome (MetS) during adulthood, particularly in Asians.

Methods: Adolescent anthropometric and fitness data were collected during the participants' high school years (N = 15,896) and their corresponding health examination data from adulthood were taken from the National Health Insurance Corporation (NHIC) in Korea. A total of 1,006 participants (6.

The association between pentraxin 3 and insulin resistance in obese children at baseline and after physical activity intervention.

Background: The role of pentraxin-3 (PTX3) in the development of insulin resistance is still not clear. We aimed to test 1) whether circulating PTX3 levels are associated with insulin resistance and 2) whether changes in PTX3 levels after the physical activity are associated with changes in insulin resistance.

Methods: Fifty-seven overweight or obese children (39 boys, 18 girls; age: 12.

Associations between Fatness, Fitness, IGF and IMT among Obese Korean Male Adolescents.

Background: The purpose of this study was to investigate the association between obesity, fitness levels and cardiovascular (CVD) risk factors, and to identify the correlation between of insulin-like growth factor (IGF)-1, IGF binding protein-3 (IGFBP-3), and carotid intima media thickness (IMT) in Korean adolescents.

Methods: A total of 225 high school males with a mean age of 16.96±0.

Association between Obesity and Physical Fitness, and Hemoglobin A1c Level and Metabolic Syndrome in Korean Adults.

Background: The purpose of the current study was to investigate the association of obesity level, physical fitness level, hemoglobin A1c (HbA1c) level and metabolic syndrome (MetS) risk factors among Korean adults.

Methods: A total of 557 adults (272 males and 285 females) who underwent medical check-up at local hospital were recruited. In addition to regular health check-up, cardiopulmonary fitness, muscular endurance were measured and their association were analyzed.

The Relationship between the Level of Fatness and Fitness during Adolescence and the Risk Factors of Metabolic Disorders in Adulthood.

Background: The purpose of the current study was to investigate the association between the level of obesity and physical fitness (PF) during adolescence and the risk factors of metabolic disorders during adulthood.

Methods: In the current analysis, 3,993 Korean adults (mean age, 38.70 +/- 1.

Reduced serum vaspin concentrations in obese children following short-term intensive lifestyle modification.

Background: Recently, visceral adipose tissue-derived serpin (vaspin) was identified as a potential insulin sensitizing adipokine, however, the factors determining the levels of circulating vaspin levels have not been fully understood. We investigated the association between adiposity, insulin resistance, lipid profiles and inflammatory markers including vaspin levels, and the effects of short-term intensive lifestyle modification on circulating vaspin levels in overweight or obese children.

Methods: A total of 50 (25 boys, 25 girls) overweight or obese children aged 11 to 13 years (average age: 12.

Middle-aged women's awareness of cholesterol as a risk factor: results from a national survey of Korean Middle-aged Women's Health Awareness (KomWHA) study.

Background: Dyslipidemia, a risk factor for cardiovascular disease (CVD), is more prevalent in middle-aged women than in men of the same age in Korea. This study, the first national survey that focused on cholesterol in Korean women, aimed to: (1) assess their awareness and knowledge of cholesterol, (2) evaluate their risk reduction behavior, and (3) examine differences in these variables among geographical regions in Korea.

Methods: A questionnaire survey study was conducted in a randomly selected national sample of 1304 Korean women, aged 40-64 years in 3 geographic regions.

Improved insulin sensitivity and adiponectin level after exercise training in obese Korean youth.

Objective: The objective of this study was to investigate the association among adiposity, insulin resistance, and inflammatory markers [high-sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, and tumor necrosis factor (TNF)-alpha] and adiponectin and to study the effects of exercise training on adiposity, insulin resistance, and inflammatory markers among obese male Korean adolescents.

Research Methods And Procedures: Twenty-six obese and 14 lean age-matched male adolescents were studied. We divided the obese subjects into two groups: obese exercise group (N = 14) and obese control group (N = 12).
