Purpose: Regular physical activity is beneficial in reducing disease activity and morbidity in patients with rheumatoid arthritis (RA). The purposes of this study were to examine the levels of regular physical activity and learned helplessness and to identify factors influencing in participation in regular physical activity in RA patients. Methods: This cross-sectional study was conducted with 210 RA patients in a university-affiliated hospital. Participants completed a questionnaire including demographic and disease-related characteristics, physical activity and learned helplessness. Data were analyzed with descriptive statistics, $x^2$ tests, t-tests, and multivariate logistic regression analyses. Results: About 23% of RA patients engaged in at least 30 minutes of regular physical activity per week. Patients with being older (OR=1.09, 95%CI=1.03~1.14), no employment status (OR=0.17, 95% CI=0.07~0.42), and lower levels of learned helplessness (OR=0.58, 95% CI=0.34~0.96) had significantly higher chance of engaging in regular physical activity. Conclusion: In developing nursing interventions to promote regular physical activity in RA patients, their learned helplessness should be considered.

Purpose: The purpose of this study was to identify the influence of physical activity and depression on sleep quality among the young-old and old-old community-dwelling elderly. Methods: Participants were 216 community-dwelling older adults in Korea aged 65 or above. Data were collected using structured questionnaires with face-to-face interviews that included demographic and health-related characteristics, International Physical Activity Questionnaires (IPAQ), the Short Form Geriatric Depression Scale (SGDS) and the Pittsburgh Sleep Quality Index (PSQI). A hierarchical multiple regression was conducted to examine whether physical activity and depression would predict sleep quality under other controlled factors. Results: There were differences in demographic and health-related characteristics, physical activity, and depression by age groups, but not in sleep quality. In the young-old elderly, physical activity (${\beta}=-0.22$, p=.043) and depression (${\beta}=0.31$, p=.002) were significantly associated with sleep quality (F=4.46, p=.001, Adjusted $R^2=.16$). In the old-old elderly, physical activity (${\beta}=-0.29$, p=.001) and depression (${\beta}=0.41$, p<.001) were significantly associated with sleep quality (F=10.79, p<.001, Adjusted $R^2=.29$). Conclusion: These finding highlight physical activity and depression as important contributors to sleep quality in both young-old and old-old elderly.

Purpose: The purpose of this study was to measure the level of expectations regarding aging (ERA) and identify relationship between ERA and physical activity of middle aged adults. Methods: Participants were middle aged adults who resided in the community in three cities in Korea. Data were collected using questionnaires that contained items on individual characteristic, International Physical Activity Questionnaires (IPAQ), and behavior-specific cognitive factors including ERA-12. Hierarchical multiple regression was conducted to examine whether ERA would predict physical activity by controlling other factors. Results: The mean age of the participants was $51.1{\pm}6.9$ years. The mean score for ERA (possible range=0 to 100) was $40.04{\pm}14.31$. More than half of the participants (62.6%) were not engaged in health promoting physical activity. Gender, employment status and exercise confidence were associated with level of physical activity (F=7.14, p<.001, $R^2=.36$). After controlling for individual factors and behavior-specific cognitive factors, ERA was independently related to physical activity (F=7.19, p<.001, $R^2=.38$). Conclusion: The results demonstrate that individuals' belief about aging has effects on physical activity in Korean middle aged adults. Thus, nursing interventions which focused on ERA could help enhance physical activity in middle aged adults.

Purpose: This study was conducted to identify relationships among Yangsaeng, activities of daily living (ADL), and physical activity in the elderly in Korea. Methods: A total of 257 subjects (ranged 60-88 yr of age) was recruited through convenient sampling. Data were collected with a self-reported questionnaire from March 2 through 25, 2009. Collected data were analyzed with SPSS/PC WIN 15.0. Results: The level of Yangsaeng was significantly different according to the level of health recognition (p<.05). The level of ADL was differed significantly according to age, successful aging, cohabitation, and health recognition. Physical activity was also significantly different according to age, educational level, cohabitation, (r=.385; p<.05) and health cognition (p<.05). The level of Yangsaeng was significantly correlated with ADL (r=.448) and physical activity (r=.385; p<.05). Conclusions: These findings help in understanding the health status of community-dwelling elders and suggest that promoting the Yangsaeng can be an effective intervention as a health promotion program for the elderly in Korea.

Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women's Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having healthy eating practices, 34% had moderate eating practices and 37% had poor eating practices based on nutrition guidelines. The study found positive changes in the decreased intake of fast foods (90%), red meat (70%) and increased intake of fruits (85%) and vegetables (78%). Generally, breast cancer survivors with healthy eating practices had better global quality of life, social, emotional, cognitive and role functions. Results showed that only 12 women (12%) met the criteria for regular vigorous exercise, 22% had regular moderate-intensity exercise while the majority (65%) had low-intensity physical activity. Breast cancer survivors with higher level of physical activity had better emotional and cognitive functions. Healthy eating practices and physical activity can improve quality of life of cancer survivors. Health care professionals should promote good dietary habits and physical activity to improve survivor's health and quality of life.

Purpose: This study investigated the muscle activity of the lower trapezius (LT) during three different shoulder flexion exercises. Methods: Twenty-three subjects between 20 and 25 years of age were enrolled. The subjects were asked to perform three different shoulder flexion exercises: 1) shoulder flexion in prone (SFP), 2) shoulder flexion in push-up with a swiss ball (SFPUS) and 3) shoulder flexion in a quadruped position with a swiss ball (SFQPS) in random order. The muscle activity of LT during each shoulder flexion exercise was measured by using surface electromyography. The muscle activity of LT was compared using one-way analysis of variance (ANOVA) and Bonferroni post hoc test among three different shoulder flexion exercises. The statistical significance level was set at α=0.01. Results: The muscle activity of LT was significantly different among three different shoulder flexion exercises (SFP, SFPUS, and SFQPS). The LT muscle activity with SFQPS exercise was greater than SFP and SFPUS exercises (p<0.01). There was no significant difference in LT muscle activity between SFP and SFPUS exercises (p>0.01). Conclusion: The LT muscle activity was greater during SFQPS than SFP and SFPUS. Therefore, SFQPS exercise can be recommended for selectively activation of LT muscle.

Objective: The purpose of this study was to investigate the muscle activity ratio of the lower limb according to changes in straight leg raise (SLR) test angles on hamstring muscle shortening during squat exercises. Design: Randomized controlled trial. Methods: The subjects were 14 healthy adults who were informed of and agreed to the method and purpose of the study. The participants were classified into SLR groups according to two angles (over $80^{\circ}$ or under $80^{\circ}$) assessed using the SLR tests. After training and practicing the wall squat posture to be applied to the experiment, electromyography (EMG) was used to measure changes in muscle activity during the performance of a wall squat. After stretching, a sequence of pre-stretch tests were performed again, and the active and passive SLR tests were also reconducted; thereafter, a wall squat was performed again by attaching EMG electrodes. The EMG results before and after stretching were compared. Results: The muscle activity of the vastus lateralis oblique muscle increased in both groups. The muscle activity of the vastus medialis oblique muscle decreased in over both group. Rectus femorus activity increased in the under 80-degree groups but decreased in the over 80-degree group. The muscle activity of the biceps femoris muscle decreased after stretching in the over 80-degree group and increased in the under 80-degree group, and the semitendinosus muscle activity after stretching was decreased. The quadriceps-to-hamstring muscle (Q:H) ratio before and after stretching between groups showed that the hamstring muscle ratio decreased after stretching in both groups. Conclusions: The results of this study showed that the Q:H ratio before and after stretching between groups was not significantly different.

Purpose: This study was conducted to examine the personal and social environmental factors affecting leisure time physical activity (LTPA) among adults living in rural communities. Methods: A cross-sectional study was conducted with a convenience sample of 282 adults living in three rural towns of Chungcheongbuk province. Leisure time physical activity was assessed through the Korean version of the Global Physical Activity Questionnaire (GPAQ), and social influence and social cohesion of social environment were assessed using reliable and validated measures. Multiple logistic regression analysis was conducted to explore personal and social environmental factors associated with LTPA. Results: The overall prevalence of leisure-time physical activity (LTPA) was 40.0%. Multiple logistic regression analysis showed that LTPA participation was associated with gender (OR=2.60, 95% CI=1.47-4.58), healthy eating (OR=1.15, 95% CI=1.01-1.31), unhealthy eating (OR=0.70, 95% CI=0.53-0.93) and social influence for physical activity (OR=1.11, 95% CI=1.03-1.20). However, social cohesion was not correlated with engaging in LTPA. Conclusion: Both personal and social environmental factors are associated with LPTA among rural adults living in Eup-Myen regions. Interventions to promote LTPA would likely benefit from considering healthy dietary intake and social influence for physical activity.
