Purpose: The purpose of the study is to investigate the degree of fatigue and its related factors in patients with breast cancer. Method: The subjects of this study consisted of 62 breast cancer patients receiving chemotherapy. The Revised Piper Fatigue Scale, Disruption of Usual Activity Scale, Linear Analogue Self Assessment Scale and Self-Care Diary Scale were employed to measure fatigue, disruption of usual activity, mood state and physical symptom respectively. Collected data were analyzed using SPSS-PC to obtain summary statistics for the descriptive analysis, Pearson Correlation, and Stepwise Multiple Regression. Result: The results are as follows. 1. The mean score of the degree of fatigue was 4.82 points indicating moderate level. 2. The mean score of the degree of disruption of usual activity, mood state and physical symptom were 2.66, 5.00, and 4.69 points. 3. Fatigue of the subjects was significantly correlated with disruption of usual activity(r=.517, p<.01), mood state(r=.420, p<.01) and physical symptom(r=.463, p<.01). 4. With the result of stepwise multiple regression, disruption of usual activity, mood state and physical symptom being the three variables which could explain fatigue by 39.1%. The results of this study suggest that comprehensive intervention strategy for fatigue should be developed to maintain quality of life during and following chemotherapy considering these factors.

Objectives : The physical activity of Korean adolescents and its distribution based on social characteristics have not yet been fully assessed. This study intends to reveal the distribution of physical activity by its subgroups and offer possible explanatory variables. Methods : The 3rd Korea Youth Risk Behavior Web-based Survey was analyzed for this study. The appropriateness of physical activity was defined by Korea s Health Plan 2010 and physical inactivity was assessed independently. Family affluence scale, parents education levels, subjective economic status, grade, and school location were considered explanatory variables. All statistical analysis was conducted using SAS ver. 9.1. Results : The proportion of participants engaging in vigorous physical activity was high in males (41.6%), at a low grade (38.5%), within the high family affluence scale group (35.5%). The distribution of participants engaging in moderate physical activity showed similar patterns, but the overall proportion was lower (9.8%). Low family affluence and students with lower subjective economic status reported a higher prevalence of physical inactivity. In multiple logistic regression analysis for physical activity, significant factors included family affluence scale (p<0.05). For physical inactivity, family affluence scale, parents education levels, and subjective economic status were included as significant factors (p<0.05). Conclusions : The results suggest that the physical activity and inactivity of adolescents may be affected by socioeconomic variables, such as family affluence scale. This implies the need to take proper measures to address these socio-economic inequalities.

Objectives: This study aims to assess the relationships between individual, social and physical environmental correlates and physical activity (PA) and sedentary behavior (SB) in Korean children. Methods: A total of 1,134 elementary school students (512 boys, $5^{th}$ and $6^{th}$ graders) in Seoul participated in the survey including self-reported moderate and vigorous intensity PA and SB as well as demographic and psychological correlates. These data were matched them with school- and community-level environmental data from the government sources. The relationships of the multilevel correlates with PA and SE were analyzed using gender-specific hierarchical regression analysis. Results: Boys were more active than girls, but there was no gender difference in SB. Students with higher levels of self-efficacy were more likely to participate in moderate and vigorous PA. There were gender-specific associations between social and physical environments correlates and PA. Boys with higher levels of self-esteem and self-efficacy were less likely to involve in SB. Girls in the $6^{th}$ grade were more likely to involve in SB. Conclusions: In order to encourage PA and discourage SB in children, school- and community-level environmental support should be considered along with programs to improve self-efficacy and self-esteem.

Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.

Despite well-known benefits of physical activity for older adults, most older adults remain significantly underactive. The purpose of this study was to examine the effects of an inclusive, choice-based physical activity promotion program to increase lifetime physical activity levels of seniors on physical activity & health-related quality of life outcomes in older adults. The physical activity promotion program guided participants to choose activities that took into account their health, preferences, and abilities. It offered information on ways for them to exercise safely, motivate themselves, overcome barriers, and develop a balanced exercise regimen. A six-month comparison-group trial was conducted with older adults in community senior center. Changes in self-reported physical activity & health-related quality of life(SF-36) by group & within group were evaluated using t-test. Of 30 subjects, 22(73%) completed the trial. Subjects were aged 63 to 75 years(mean=$68.36{\pm}4.02$); 86% were female. The intervention group increased estimated caloric expenditure by 1975 calories/week in moderate intensity activities(MET${\geq}3.0$; p=.008), and by 2312 calories/week in physical activities of any intensity(p=.005). Between-group analyses showed that the changes were significantly different in both measures(p=0.17; p=032). The intervention group also significantly better scores on general health perception(p=.031) & vitality(p=.002). Individually tailored programs to encourage lifestyle changes in seniors may be effective and applicable to health care and community settings.

Purpose: The purpose of this study was to review the effects of physical activity on musculoskeletal outcomes in older Koreans. Methods: Experimental studies were retrieved from the search engines (PubMed, CINAHL, PsycINFO, Cochrane, RISS, KISS, and KoreaMed). The selected studies for analysis were 27 articles of musculoskeletal outcomes (gait, muscle strength, flexibility, balance, grip strength, endurance, body fat, and weight) from 515 articles. Results: The most common type of physical activity was a resistance exercise. There were significant improvements in gait (71.4%), muscle strength (86.7%), flexibility (63.6%), balance (72.2%), grip strength (71.4%), endurance (71.4%), body fat (57.1%), and weight (28.6%). The activity programs that apply over 150 minutes a week showed greater improvement of 69.5% than 65.0% from those did not meet the guidelines totally. Conclusion: Based on the review, we conclude that regular physical activity in the elderly may improve the musculoskeletal outcomes. To be more effective programs, it is necessary to meet the guidelines of 150 minutes a week or 30 minutes of moderate-intensity activities on 5 days per week for the elderly.

Objectives: Cardiovascular disease is a major cause of death in the elderly in Korea. Increased arterial stiffness is linked to risk of cardiovascular disease and mortality. The purpose of this study was to investigate the relationship between arterial stiffness and physical activity in the elderly. Methods: A total of 209 older adults (110 men and 99 women) participated in this study. Arterial stiffness of subjects such as brachial-ankle pulse wave velocity (baPWV) and ankle brachial pressure index (ABI) was measured using a non-invasive vascular screening device (VP-1000 Plus, Omron, Kyoto, Japan). The interviewed Korean version of the international physical activity questionnaire short form (IPAQ-SF) was used to evaluate subject's physical activity level and classify subjects as active or inactive group based on the time spent doing moderate to vigorous physical activity (MVPA). Results: The mean age of total subjects was 75.3 ± 5.6 years. There was no significant difference in sex distribution between the active group (39.7%) and inactive group (60.3%). The baPWV (1,758.1 ± 375.2 cm/sec) of the active group was significantly lower than that (1,969.7 ± 372.3 cm/sec) of the inactive group (P < 0.05). There was a significant inverse association between time spent in MVPA and baPWV (r = -0.245, P < 0.01). Conclusions: This study suggests that physical activity programs for older adults are needed to prevent arteriosclerosis.

Objectives: This study aimed to investigate arterial stiffness index, physical activity, and food and nutrient intake in middle-aged adults over 40 years when the incidence of cardiovascular disease begins to increase. Methods: This study included 106 subjects (48 males and 58 females) aged between 40 and 64 years. The arterial stiffness index (brachial-ankle pulse wave velocity [baPWV], and ankle-brachial index [ABI]) were measured using a blood pressure pulse wave testing device. Physical activity was assessed using the Korean version of the Global Physical Activity Questionnaire, and food and nutrient intake was calculated using the Food Frequency Questionnaire. Results: The mean age of the subjects was 54.4 years. Although the ABI of the subjects was within the normal range, they were divided into tertiles to compare physical activity and food and nutrient intake. In males, the time spent on moderate to vigorous physical activity (MVPA) was significantly higher in T3 (600.6 min/week) than in T1 (304.4 min/week). In females, the time spent in sedentary behavior was significantly lower in T3 (294.5 min/week) than in T1 (472.1 min/week). In addition, the frequency of fish consumption was significantly higher in T3 (1.27 frequency/day) than in T1 (0.64 frequency/day) in females. Polyunsaturated fatty acid (PUFA) and ω-3 fatty acid intake, adjusted for energy intake, were significantly positively correlated with ABI (r = 0.200 and r = 0.218, respectively). Conclusions: High MVPA (in males), low sedentary behavior (in females), and PUFA and ω-3 fatty acid intake through fish consumption may be associated with low peripheral artery stiffness. Therefore, arteriosclerosis can be prevented through physical activity and proper dietary therapy.

In the present work we investigated the effect of regular physical exercise on the activities of erythrocyte antioxidant enzyme, plasma total radical-trapping antioxidant potential(TRAP) and plasma level of lipid peroxidation(malondialdehyde, MDA) in 64 healthy male, aged 34-67 years. The study population were divided in two groups: small amount of exerciser(exercise time less than 10min/d) and moderate amount of exerciser(exercise time more than 20min/d) according to their physical exercise habits measured by a questionnaire. Erythrocyte superoxide dismutase(SOD), glutathione peroxidase(GSH-Px) and catalase(CAT), plasma TRAP, as well as plasma MDA were determined. Erythrocyte GSH-Px and plasma TRAP were higher in moderate amount of exercisers than those in small amount of exercisers by 17% and 26%, respectively. No significant differences were observed in erythrocyte SOD, CAT and plasma MDA between the two groups. Mean exercise time was positively correlated with the erythrocyte GSH-Px activity and plasma TRAP significantly. The results would sugest that regular moderate exercise enhances antioxidant defences against reactive oxygen species and may increase the likelihood of a healthier life span.
