Physical inactivity may an important outcome in the prognosis of breast cancer. Physical activity levels decrease significantly for breast cancer patients following the treatment and remain low after oncology treatment is completed. The aim of this study was to determine physical activity levels and to examine associations among physical activity, comorbidity, functional capacity, peripheral muscle strength, and psychosocial status in breast cancer patients. Forty breast cancer survivors were included in this study. Demographic and clinical characteristics were recorded. Physical activity was assessed with a short form of the International Physical Activity Questionnaire (IPAQ). We defined comorbid diseases according to the Charlson Comorbidity Index (CCI). Functional capacity was evaluated with a six-minute walk test (6MWT). Peripheral muscle strength was measured for quadriceps femoris muscle with a hand-held dynamometer. Psychosocial status was measured with the Hospital Anxiety Depression Scale (HADS). Forty percent of patients were inactive. The IPAQ total score was significantly related with quadriceps muscle strength (r=0.492; p<0.001) and HADS depression score (r=0.341; p<0.05). Marked correlations were also observed between IPAQ walking score and quadriceps muscle strength (r=0.449; p<0.001), HADS depression score (r=0.341; p<0.05), and CCI (r=-0.433; p<0.001). The CCI score was also markedly associated with quadriceps muscle strength (r=-0.413; p<0.001). 6MWT distance was not significantly correlated with any of the parameters. Regression analyses revealed that psychosocial status and peripheral muscle strength were significant predictors of physical activity estimated with the IPAQ short form and when combined, they explained 35% of the variance. Comorbidities, peripheral muscle strength and psychosocial status partially explain the variability of physical activity level in breast cancer survivors. These results suggest that physical inactivity contributes to worsening health in breast cancer survivors.

Objectives: This study performed to verify Korea National Health and Examination Survey(KNHAES) to monitor recommended physical activity(PA) and to propose an monitoring tools for evidence-based PA projects. Methods: The characteristics of the Global Physical Activity Questionnaire(GPAQ) and its reliability and validity were overviewed based on the current scientific evidence in the field of PA. Relevant articles were identified through multiple sources including PubMed, Science Direct, Scopus, CINAHL, ASP, RISS4U, and KISS. Results: The GPAQ has strong points over the Short Form of International Physical Activity Questionnaire(IPAQ-SF) as a monitoring tool to meet recommended PA levels for three domains separately and reflecting a better understanding about walking. Its reliability and validity also were reported as acceptable in existing studies overall. Some limitations of this questionnaire, however, need to be addressed to improve its quality. Conclusions: For monitoring of evidenced-based physical activity projects, we considered that it is able to be provided an opportunity for in-depth discussion among academic experts and policy-makers about the necessity of complements for KNHAES and applying new tools, and it could be the basis for development of physical activity monitoring tool in the future.

The purpose of this study was to investigate the dietary behavior, health-related lifestyles and nutrient intake status of college students according to physical activity levels. The physical activity levels were measured using the Korean version of the International Physical Activity Questionnaire (IPAQ) short form. The subjects of this study were 438 college students (243 males and 195 females) in Incheon area and were divided by gender and by physical activity levels, which included low, moderate and high physical activity groups. The average age of male and female students were 23.7 and 21.0 years old, respectively. The prevalence of the low physical activity group was 11.5% for males and 30.8% for females and that of the high physical activity group was 38.7% for males and 22.6% for females. According to the criteria for obesity in Asia-Pacific region, 39.1% of the males and 64.1% of the female students investigated were in the normal range of BMI and 30.9% of the males and 4.6% of the female students were in the obesity category. However, percent of body fat in the female students was significantly higher than that of the male students. The soft lean mass of the high physical activity group was higher compared to the other groups. In the low physical activity group, frequency of “eating out” was lower compared to the other groups. The average consumption of energy was 74.4% for males and 80.1% for females of the estimated energy requirement (EER). The mean intakes of vitamin C, vitamin B2, folic acid and Ca were 67.3%, 84%, 52.7% and 36.7% for males and 64.8%, 99.9%, 51.1% and 40.1% for females of recommended intake (RI), respectively. Therefore, it was necessary for obesity prevention as well as health promotion to increase physical activity and to eat an adequate, balanced diet in female college students.

Background: The aim of this study was to examine the association between physical activity and periodontitis in the Korean population. Methods: This study utilized data from 9,191 participants of the Korea National Health and Nutrition Examination Survey. Periodontitis was defined as a CPI score of 3 or 4. Physical activity was assessed by the trained interviewer using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). IPAQ-SF is composed of vigorous physical activity, moderate physical activity, and walking activity. Multivariable logistic regression analyses and stratified analyses by obesity were performed. All analyses were conducted separately for males and females. Results: Females who engaged in vigorous and moderate physical activity had a 28% (OR = 0.72, 95% CI = 0.54 - 0.95) and 34% (OR = 0.66, 95% CI = 0.44 - 0.98) lower risk of periodontitis, respectively. In obese females, moderate physical activity in obese had a 65% lower risk of periodontitis (OR = 0.35, 95% CI = 0.18 - 0.67). Conclusions: Our findings suggest that moderate-intensity physical activity was inversely associated with a lower risk of periodontitis. In obese females, moderate physical activity had an independent inverse association with periodontitis.

Purpose: The purpose of this study was to examine the effects of a daily life-based physical activity enhancement program performed by middle-aged women at risk for cardiovascular disease. Methods: This study used a randomized control group pretest-posttest design. Middle-aged women aged 45 to 64 were recruited from two outpatient cardiology departments, and randomly assigned to an experimental group (n=28) and a control group (n=30). For the experimental group, after providing one-on-one counseling and education, we provided customized text messages to motivate them in daily life. To monitor the practice of physical activity, they also used an exercise diary and mobile pedometer for 12 weeks. Subjects' physical activities (MET-min/week) were measured using the International Physical Activity Questionnaire (IPAQ). Their physiological data were obtained by blood tests using a portable analyzer, and the data were analyzed using the SPSS 21.0/WIN program. Results: There were significant differences in exercise self-efficacy, health behavior, IPAQ score, body fat, body muscle, and fasting blood sugar between the two groups. However, there were no significant differences in total cholesterol, hemoglobin A1c, high-density lipoprotein cholesterol, and waist-to-hip ratio. Conclusion: Strengthening physical activity in daily life without being limited by cost burden and time and space constraints. Therefore, it is essential to motivate middle-aged women at risk for cardiovascular disease to practice activities that are easily performed in their daily lives.

Based on the their BMI, normal was 67.2%, underweight was 5.4%, overweight was 17.8%, and obesity was 9.6%. The normal rates of male and female were 57.7% vs. 78.7%. The results of BSQ were indicated 48.2% of participants was dissatisfied, and the rates of male and female were 22.9% vs. 82.3%. The results of EAT-26 showed that 20.2% of participants had abnormal eating attitude, and the rates of male and female were 7.3% vs. 37.4%. 99% of participants was physically active. All variables were statistically different between gender. There was positive correlation between body image and eating attitude in male and female students, and BMI was correlated with body image and eating attitude in male students. However, physical activity was no relationship with other variables. In conclusion, physical education students had high rate of dissatisfied in body image and rate of abnormal eating attitude. In addition, the higher dissatisfied in body image was the more abnormal eating attitude. Therefore, the proper education about weight management and change of social awareness may be needed.

Purpose: The purpose of this study was to examine the effects of a walking program for office workers in terms of social cognitive theory, walking activities and physiological indexes. Methods: A nonequivalent control group pretest-posttest design was used. The sample consisted of 50 office workers who were identified as having low levels of physical activity according to the International Physical Activity Questionnaire (IPAQ Research Committee, 2005). The participants were recruited from two companies in Seoul. Of the 50 participants, 26 were assigned to the non-equivalent experimental group and 24 to the control group. The walking program consisted of six didactic sessions via e-mail, two individual telecoaching sessions and three support group meetings over ten weeks. Data were analyzed using SPSS 17.0 program. Results: The non-equivalent experimental group reported significantly higher posttest scores in walking activities and adhering to the walking protocol than the control group. There were no differences in reported self-efficacy, outcome expectations, body mass index and blood pressure between the two groups. Conclusion: These findings indicate that a walking program based on social cognitive theory is effective in increasing physical activities for office workers.
