Background: This study was conducted to determine the relationship between lifestyle behavior and quality of life (QoL) among cancer survivors in Korea. Materials and Methods: Data for a total of 471 (173 men, 298 women) cancer survivors (CS) over 40 years old were obtained from the database of the $4^{th}$ Korean National Health and Nutrition Examination Survey (KNHANES IV). An identical number of subjects of the same age, sex, and education who had no restrictions in physical activity were randomly selected from the database and represented the control group (CG). Drinking, smoking, and exercise behavior were assessed. Results: The number of heavy drinkers was lower in CS (9.4%) than in CG (15.8%) (p<0.01); similarly, there were fewer smokers in CS (9.1%) than in CG (14.0%) (p<0.05). The percentage of individuals engaging in vigorous, moderate, and low-intensity exercise did not differ between CS (13.6%, 14.7%, and 50.0%) and CG (14.3%, 13.4%, and 49.7%, respectively). No differences in Euro QoL Questionnaire 5-Dimensional Classification (EQ-5D) scores on both drinking and smoking behaviors were noted. Compared to the non-exercisers, the low-intensity exercisers in CG ($0.91{\pm}0.10$ vs. $0.94{\pm}0.09$), vigorous-intensity exercisers in CS ($0.84{\pm}0.62$ vs. $0.91{\pm}0.11$), and low-intensity exercisers in CS ($0.82{\pm}0.22$ vs. $0.88{\pm}0.13$) scored higher on the EQ-5D. Conclusions: Although cancer survivors practiced more conscious health behavior in drinking and smoking, their engagement in exercise did not differ from that of non-cancer survivors. Since exercise engagement increases QoL in general, implementation of an educational program that promotes exercise engagement in cancer survivors may be required.

The purpose of this study was to evaluate the prevalence of obesity, dietary habits, and nutritional status by age among low-income women, using data from the fourth Korea National Health and Nutrition Examination Survey (2007~2009). Subjects were 8,356 women aged 20 and over. The subjects were classified into four groups by age. Dietary data from 24-hr recall methods were used to analyze nutritional status. The prevalence of obesity in the 50~64 years age group was significantly higher than those of the other age groups. Among age groups, malnutrition was the highest in the 65-and-over age group. It appears that women in the 20~29 and 65-and-over age groups were the highest nutritional risk. The percentage of carbohydrates in total energy intake was higher and the percentages of protein and fat were lower in the 65-and-over age group than other groups. Frequency of skipping breakfast was lower in women aged 65-and-over, and moderate physical activity significantly decreased with increasing age. Awareness of dietary guidelines was higher in women aged 30~49 years than other groups, whereas it was lower in those aged 65-and-over years. Adherence to dietary guidelines of 'eating a variety of foods from each food group' was significantly lower in women aged 65-and-over years than those of other groups. However adherence to dietary guidelines of 'eating breakfast everyday with a pleasant mind' was significantly lower in women aged 20~29 years than those of other groups. Therefore, this study shows that low income women have various nutritional problems by age group, and we should support a tailored approach to improve their nutritional status.

Over the last few decades, the rates of pediatric obesity have more than doubled regardless of sociodemographic categorization, and despite these rates plateauing in recent years there continues to be an increase in the severity of obesity in children and adolescents. This review will discuss the pediatric obesity mediated cardiovascular disease (CVD) risk factors such as attenuated levels of satiety and energy metabolism hormones, insulin resistance, vascular endothelial dysfunction, and arterial stiffness. Additionally, early intervention to combat pediatric obesity is critical as obesity has been suggested to track into adulthood, and these obese children and adolescents are at an increased risk of early mortality. Current suggested strategies to combat pediatric obesity are modifying diet, limiting sedentary behavior, and increasing physical activity. The effects of exercise intervention on metabolic hormones such as leptin and adiponectin, insulin sensitivity/resistance, and body fat in obese children and adolescents will be discussed along with the exercise modality, intensity, and duration. Specifically, this review will focus on the differential effects of aerobic exercise, resistance training, and combined exercise on the cardiovascular risks in pediatric obesity. This review outlines the evidence that exercise intervention is a beneficial therapeutic strategy to reduce the risk factors for CVD and the ideal exercise prescription to combat pediatric obesity should contain both muscle strengthening and aerobic components with an emphasis on fat mass reduction and long-term adherence.

Objectives: Reduced glucose utilization in the main parts of the brain involved in memory is a major cause of Alzheimer's disease, in which ketone bodies are used as the only and effective alternative energy source of glucose. This study examined the effects of a low-carbohydrate and high-fat (LCHF) diet supplemented with a ketogenic nutrition drink on cognitive function and physical activity in the elderly at high risk for dementia. Methods: The participants of this study were 28 healthy elderly aged 60-91 years showing a high risk factor of dementia or whose Korean Mini-Mental State Examination (K-MMSE) score was less than 24 points. Over 3 weeks, the case group was given an LCHF diet with nutrition drinks consisting of a ketone/non-ketone ratio of 1.73:1, whereas the control group consumed well-balanced nutrition drinks while maintaining a normal diet. After 3 weeks, K-MMSE, body composition, urine ketone bodies, and physical ability were all evaluated. Results: Urine ketone bodies of all case group subjects were positive, and K-MMSE score was significantly elevated in the case group only (p=0.021). Weight and BMI were elevated in the control group only (p<0.05). Grip strength was elevated in all subjects (p<0.01), and measurements of gait speed and one leg balance were improved only in the case group (p<0.05). Conclusions: We suggest that adherence to the LCHF diet supplemented with a ketogenic drink could possibly influence cognitive and physical function in the elderly with a high risk factor for dementia. Further, we confirmed the applicability of this dietary intervention in the elderly based on its lack of any side effects or changes in nutritional status.

Background: Qigong is highly favoured among Asian breast cancer survivors for enhancing health. This study examined the hypothesis that quality of life (QoL) in the Qigong group is better than the placebo (aerobic) or usual care group. Materials and Methods: A total of 197 participants were randomly assigned to either the 8-week Kuala Lumpur Qigong Trial or control groups in 2010-2011. Measurement taken at baseline and post-intervention included QoL, distress and fatigue. Analysis of covariance (ANCOVA) and Kruskal Wallis were used to examine for differences between groups in the measurements. Results: There were 95 consenting participants in this 8week trial. The adherence rates were 63% for Qigong and 65% for the placebo group. The Qigong group showed significant marginal improvement in Quality of life scores compared to placebo (mean difference=7.3 unit; p=0.036), compared to usual care (mean difference=6.7 unit; p=0.048) on Functional Assessment Cancer Therapy-Breast measure. There were no significant changes between the placebo and usual care groups in fatigue or distress at post intervention (8-week). Conclusions: Cancer survivors who participated in the Qigong intervention showed slightly better QOL. Follow up studies are greatly needed to evaluate which subgroups may best benefit from Qigong. With a steep rise of cancer survivors, there is an urgent need to explore and engage more cultural means of physical activity to fight side effects of treatment and for cancer control in developing countries.

본 연구는 불소 미방출 치면열구전색제 $Concise^{TM}$에 제조한 생체활성 유리 나노입자(bioactive glass nano particles: BGn)를 0.5, 1.0, 2.0 wt%를 첨가하여 새로운 치면열구전색제를 조성하고 세균부착실험을 통한 세균부착 억제 효과와 물성을 평가 하였다. 물흡수도와 용해도는 ISO 4049(2009) 규격에 맞추어 직경 10 mm, 두께 2 mm 시편을 제작하여 무게를 측정하여 산출하였으며 세균부착효과는 S. mutans, S. aureus, E. coli 3개의 균주를 이용하여 평가하였다. 실험 결과 물흡수도는 BGn 첨가가 증가할수록 높은 값을 보였으며 용해도는 첨가될수록 낮은 용해도를 보였다(p<0.05). 세균부착실험 결과 대조군 $Concise^{TM}$과 비교하여 BGn을 첨가한 S. mutans 실험군에서 다소 낮은 부착 양상을 보였으나 통계적 유의한 차이는 나타나지 않았으나, S. aureus 실험군과 E.coli 실험군에서는 통계적 유의한 차이를 보였다(p<0.05). 이는 BGn의 세균부착 억제 효과가 있음을 입증한 것이라 사료된다. 향후 BGn 첨가양에 따른 효율성과 폭 넓은 물성 연구가 필요할 것으로 사료된다.
