To date, numerous investigations have identified the role of exercise and physical activity in prevention and treatment of Type 2 diabetes and cardiovascular disease (CVD). This review paper analyzed epidemiological findings which investigated the effects of obesity, physical activity participation and the level of fitness levels on prevalence and risk factors of Type 2 diabetes and CVD. These studies showed that not only prevention of obesity, but also participation of physical activity and maintenance of good level of fitness are important to prevent and treat Type 2 diabetes and CVD. In addition, prevention of obesity and improvement of high fitness levels at early ages (childhood and adolescence) are important to prevent the prevalence and incidence of Type 2 diabetes and CVD.

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 +/- 1.69 years) were recruited. The level of body index (BI) and PF were examined during adolescence through high school record, and their health examination data, including systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose (FG), total cholesterol (TC), and current body mass index (BMI) were obtained from National Health Insurance Corporation Data. Gender-specific analyses were administered to compare health exam data across the level of BI, the level of PF, and a mixed level of BI and PF. RESULTS: Most obese males during high school had statistically higher SBP, DBP, FG, and BMI in adulthood, and most obese females had higher BMI, as compared to most lean males or females. Least fit males during high school had statistically higher BMI in adulthood, and least fit females had statistically higher SBP, DBP, FG, TC, and BMI, as compared to most fit males or females. There was a significant relationship between the mixed level of BI and PF and SBP, DBP, TC and current BMI in both genders. CONCLUSION: Maintaining a healthy level of body weight and PF during adolescence is recommended to prevent the development of metabolic diseases in adulthood.

PURPOSE: This study was conducted to investigate dietary habits related to weight reduction and snack intake habits of 4th to 5th grade elementary students located in Jeju-si, Jeju, South Korea. METHODS: The 4(th) and 5(th) grade elementary school students (total n = 234, equally matched numbers of normal weight children and overweight/obese children (n = 117/group)) were surveyed using a questionnaire and a 24-hour dietary recall method in Oct 2015. RESULTS: The percentage of students who experienced reduced food intake to control weight was 26.3% in the normal weight group (NG) and 77.6% in the obese group (OG). Most frequently answered meal for reduced intake was snacks in the NG and dinner in the OG. Percentages of daily calorie intake among subjects were 17.2% for breakfast, 33.8% for lunch, 29.7% for dinner, and 19.3% for snacks. Frequency of snack intake was 2.1 times a week in NG and 1.6 times a week in OG, which showed a statistical difference between body weight groups. Types of snack foods were distinctly different depending on where children consumed them, although no difference was observed between NG and OG. In addition, snack intake level of low energy and nutrient-dense foods was significantly lower in the OG compared to the NG, whereas snack intake level of energy dense and low-nutritive foods was not different between the OG and NG. CONCLUSION: Taken together, snack intake level with consideration of frequency and amount of snack intake showed that children in the OG consumed significantly less low energy and nutrient-dense foods compared to the NG. Therefore, nutritional education for choosing healthy snack foods for children regardless of body weight status is crucial based on family-school links.

Purpose: This study evaluated the nutrition and food intake status among adults in Jeju, Republic of Korea, based on their sociodemographic characteristics and obesity. Methods: Nine hundred and forty-nine adults aged 19 years or older were included based on the 2022 Jeju Nutrition and Physical Activity Survey data. A dietary assessment was conducted using a one-day, 24-hour recall method, and the nutrition status was evaluated using the 2020 Dietary Reference Intakes for Koreans. The sociodemographic status included sex, age, education, and household income, and obesity was defined as a body mass index (BMI) of ≥ 25 kg/m 2 . Results: The mean age of the subjects was 49.8 years, and the overall prevalence of obesity was 48.4% (59.5% for males and 37.2% for females). The top three insufficient nutrients consumed at less than the estimated average requirement were calcium (77.7%), vitamin A (77.3%), and vitamin C (61.3%), while 40.9% of the subjects consumed fat as more than 30% of their total energy intake. The sodium intake was approximately 1.5 times higher than the chronic disease risk reduction intake level. In terms of food groups, the participants consumed more meat (148.2 g/day), seafood (69.0 g/day), potatoes, and starches (41.6 g/day) but consumed fewer vegetables (214.3 g/day) and less dairy (62.0 g/day) than Korean adults. The nutritional status and food intake patterns differed by the sociodemographic status. In addition, the obese group consumed more poultry and beverages than the non-obese group (p < 0.05 for all). Conclusion Adults in Jeju under-consume essential nutrients while over-consuming certain nutrients, such as fat and sodium. The nutritional status also varied according to the sociodemographic characteristics. These findings suggest that sociodemographic factors should be considered carefully when developing nutritional policies and programs to improve the nutritional status and address obesity among adults in Jeju.

BACKGROUND: Physical activity, especially walking is strongly recommended to control blood glucose among type 2 diabetic patients. Furthermore, physical activity is one of the most important tools to prevent secondary diabetes complications among type 2 diabetic patients such as retinopathy, nephropathy, neuropathy etc. The purpose of the study was to examine the association between the level of walking and physical activity and glucose control among Korean adults with type 2 diabetes. METHODS: A total of 250 patients with type 2 diabetes (98 males and 152 females) were recruited (mean age = 62.1 +/- 10.2 years) in the current study. The height, weight, waist and hip circumference were measured, and the level of physical activity and total walking hour were measured by physical activity scale for elderly (PASE). High density lipoprotein cholesterol (HDL-C), total cholesterol, triglyceride, fasting glucose and oral glucose tolerance test, creatinine, uric acid, total protein, albumin, hemoglobin A1c were measured. RESULTS: After adjusting for potential covariates such as age, education, occupation income, smoking, and drinking, male patients who spent least time in walking were more likely to have 2 hour serum glucose level in oral glucose tolerance above 200 mg/dL than counterparts who spent most time in walking with age adjusted (Relative Risk (RR) = 11.75, 95% Confidence Interval (CI) = 1.94-71.00). Male patients who were in the least active group were 5.92 time (95% CI = 1.39-25.28) more likely to have 2 hour serum glucose level in oral glucose tolerance over 200 mg/dL than counterparts in the most active group. However, there was no significant finding in females. CONCLUSIONS: The current study showed that physical activity and walking are effective method to maintain glucose tolerance among type 2 diabetic male patients.

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+/-0.23 years participated in this study, and their fatness and fitness levels, fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), blood lipids, IGF-1, IGFBP-3, and IMT were measured. RESULTS: The results showed that total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), fasting insulin, HOMA-IR, IGF-1, and IGFBP-3 levels were significantly higher in the most obese group than in the other two groups (tertiles). Muscular and cardiopulmonary fitness were negatively associated with weight, body mass index (BMI), fat mass, body fat, waist circumference (WC), fasting insulin, HOMA-IR, and IMT. IGF-1 and IGFBP-3 levels were correlated with WC, hip circumference (HC), fasting glucose, TG, HDL-C, fasting insulin, and HOMA-IR. IMT levels were significantly associated with weight, BMI, muscle mass, fat mass, percent body fat, WC, HC, systolic blood pressure, diastolic blood pressure and high-sensitivity C-reactive protein. CONCLUSION: There was a significant association between increased obesity and decreased fitness and HOMA-IR, IGF, and IMT among adolescents.

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. RESULTS: The prevalence of MetS was 31.7% for males and 23.7% for females. Females with the higher muscular endurance had lower waist circumference, triglyceride level, and HbA1c level than those with the lower muscular endurance. Males with the higher level of cardiopulmonary fitness had lower diastolic blood pressure, lower high-sensitivity C-reactive protein level and higher high density lipoprotein cholesterol level than males with the lower level of cardiopulmonary fitness. Females with the higher level of cardiopulmonary fitness had lower body weight, body mass index, systolic blood pressure, and fasting blood glucose level than females with the lower level of cardiopulmonary fitness. Participants with the higher level of adiposity and the lower level of physical fitness were 5.26 times (95% confidence interval [CI], 2.19 to 12.62), 5.71 times (95% CI, 2.23 to 14.60) more likely to have MetS, respectively, in male and female compared to participants who were neither obese nor have the lower level of fitness. CONCLUSION: This study suggests that maintaining a healthy body weight as well as a certain level of fitness is important for the prevention of MetS.
