Background: Work Ability Index (WAI) is a well-known and valid self-report tool that has been widely used in various studies to identify and avoid early retirement and work-related disability. Nevertheless, very few studies have been carried out to evaluate work ability in Iran. We aimed to investigate the WAI and the effect of work-related stress on it among Iranian workers. Methods: A cross-sectional, descriptive and analytic study was carried out among 449 workers from five working sectors in three big cities of Iran. Work ability and work-related stress were measured using the Persian version of WAI and the Persian version of Health and Safety Executive Stress Indicator Tool. Results: More than a third of the workers surveyed (34.70%) did not have an appropriate level of work ability (WAI < 37). There was a significant correlation between subscales of work-related stress and the mean score of WAI. Furthermore, the variables of body mass index, sleep quality, exercise activity, job tenure, and three subscales of work-related stress including demands, supervisor support, and role were significant predictors of WAI. Conclusion: According to the results of this study, the interventional programs must be focused on improving supervisors support, eliminating ambiguity and conflicts in the role of workers in their job and organization, reducing job demands, improving sleep quality, and increasing exercise activity.

Purpose: The purpose of the study was to identify the relationship between obesity and bone mineral density in middle aged women. Methods: A cross-sectional survey design was utilized with a check list and physiological measurements. A total of 827 convenient samples were recruited from women who lived in the community. Bone mineral density was measured by T-score using the pixi method of Lumar on the left heel. Descriptive statistics and pearson correlation coefficient were utilized for data analysis. Results: Most were assessed as having normal weight(37.9%) or obese (57.4%) by BMI. Only 32% was assessed as having normal bone mineral density, while 40.3% had osteopenia, and 27.7% as osteoporosis. The BMI scores were significantly related to age, and episodes of fractures. Those with lower bone mineral density reported significantly more episodes of fractures and chronic disease. The T scores of Bone mineral density were significantly correlated with the scores of BMI (r= .126, p< .001). Conclusion: There is a strong need to develop intervention programs for this age group to manage bone mineral density loss to prevent occurrences of osteoporosis, and episodes of fracture.

Purpose: This study aimed to identify differences in contraception behavior and related factors between unmarried female and male. Methods: A cross-sectional survey design with a convenient sampling was used. From Seoul, 107 women and 96 men were recruited. A structured questionnaire was self-administered from July 14, 2008 to September 2, 2008. Results: The average ages of women and men were 26.9 and 27.8 years old, respectively. Fiftysix percent of women and 85.4% of men have experienced sexual intercourse. There were no differences between female and male in attitude toward contraception, subjective norm, and contraception behavior, while female had higher score of self-efficacy for contraception (p=.02) and intention of contraception (p=.02). There was positive correlation with subjective norm (r=.22, p<.05), self-efficacy (r=.53, p<.01) in male and attitude (r=.32, p<.05), selfefficacy (r=49, p<.01) in female. According to the result of multiple regression, the significant factor of contraception behavior was self-efficacy for both female (${\beta}$=.49, p=.00) and male (${\beta}$=.53, p=.00). Conclusion: To improve contraception behavior for unmarried female and male, it is necessary to develop proper sex education program to enhance self-efficacy for contraception. Adjusted education program by this result will contribute to increase sexual health for female and male.

Background: This study compared nutritional parameters in hemodialysis (HD) subjects and controls using bioimpedance analysis (BIA) and investigated how BIA components changed before and after HD. Methods: This cross-sectional study included 147 subjects on maintenance HD from two hospitals and 298 propensity score-matched controls from one healthcare center. BIA was performed pre- and post-HD at mid-week dialysis sessions. Results: Extracellular water/total body water (ECW/TBW) and waist-hip ratio were higher in the HD patients; the other variables were higher in the control group. The cardiothoracic ratio correlated best with overhydration (r = 0.425, P < 0.01) in HD subjects. Blood pressure, hemoglobin, creatinine, and uric acid positively correlated with the lean tissue index in controls; however, most of these nutritional markers did not show significant correlations in HD subjects. Normal hydrated weight was predicted to be higher in the pre-HD than post-HD measurements. Predicted ultrafiltration (UF) volume difference based on pre- and post-HD ECW/TBW and measured UF volume difference showed a close correlation ($r^2=0.924$, P < 0.01). Remarkably, the leg phase angle increased in the post-HD period. Conclusion: The estimated normal hydrated weight using ECW/TBW can be a good marker for determining dry weight. HD subjects had higher ECW/TBW but most nutritional indices were inferior to those of controls. It was possible to predict UF volume differences using BIA, but the post-HD increase in leg phase angle, a nutritional marker, must be interpreted with caution.

Purpose: This study aimed to identify the maternal functioning and related factors among early postpartum women. Methods: In this cross-sectional study, 243 women recruited from three women's hospitals. Participants completed a structured questionnaire in on-line or off-line between 6 and 12 weeks postpartum. Data were analyzed using descriptive statistics, the t-test, analysis of variance, Pearson correlation coefficients, and stepwise multiple regression with SPSS for Windows ver. 25.0. Results: The mean score for the maternal functioning was 73.28±16.78 out of 120 points. Maternal functioning was associated with postpartum depression (r=-.57 p<.001), and spousal and family support (r=.54, p<.001). According to the stepwise multiple regression, postpartum depression (β=-0.43, p<.001), spouse and family support (β=0.39, p<.001), employment (β=0.12, p=.012) and delivery method (β=-0.10 p=.026) had a significant relationship with the maternal functioning among postpartum women. These variables had an explanatory power of 49.0% for maternal functioning. Conclusion: It is necessary to develop and implement a maternal intervention program focused on alleviating postpartum depression and improving spouse and family support. This study will be the starting point for various studies by identifying the maternal functioning of postpartum women for the first time in Korea.

Purpose: The purpose of this study was to identify nursing students' knowledge and attitude toward advance directives and factors influencing the attitude. Methods: A cross-sectional survey design was used and 196 nursing students participated in the study. Data were collected from July 1 to August 30, 2018 using a structured questionnaire which included biomedical ethics, awareness of good death, knowledge and attitude toward advance directives. Data were analyzed using SPSS/WIN 25.0 program with descriptive statistics, t-test, ANOVA, correlation, and multiple regression. Results: The mean score of biomedical ethics, awareness of good death, knowledge and attitude toward advance directives were $2.88{\pm}0.59$, $3.18{\pm}0.48$, $7.68{\pm}31.32$, $31.00{\pm}3.09$. Factors influencing the attitude toward advance directives were awareness of good death (${\beta}=.28$, p<.001), intention of writing their advance directives (${\beta}=.19$, p=.006), the knowledge related to advance directives (${\beta}=.15$, p=.029). A total of 14% of attitude toward advance directives was explained by awareness of good death, the knowledge related to advance directives, and ntention of writing their advance directives. Conclusion: The findings of the study indicate that it is necessary to provide a systemic education program regarding advance directives for nursing students in order to provide knowledge related to advance directives and to help them establish positive attitudes toward advance directives.

Objective: We analyzed the association between regional weather and temporal changes on the daily occurrence of trauma emergencies and their severity. Methods: In this cross-sectional prospective study, we investigated daily atmospheric patterns in trauma episodes in 1,344 patients in Cheongju city, South Korea, from January 2016 to December 2016 and analyzed the association of trauma occurrence and Injury Severity Scores (ISS) with weather conditions on a daily scale. Results: The mean age of trauma patients was $53.0{\pm}23.8years$ and average ISS was $9.0{\pm}2.0$. Incidence of trauma was positively correlated with average temperature (r=0.512, P<0.001) and atmospheric pressure (r=0.332, P=0.010) and negatively correlated with air pollutants (particulate matter less than $2.5{\mu}m^3$ [PM2.5], r=-0.629, P<0.001; particulate matter less than $10{\mu}m^3$ [PM10], r=-0.679, P<0.001). ISS was not significantly correlated with climate parameters and air pollutants, and variability was observed in the frequency and severity of trauma by time of day (highest occurrence, 16-20 pm; highest ISS, 4-8 am), day of the week (highest occurrence and highest ISS, Saturday), month of the year (highest occurrence, July; highest ISS, November), and season (highest incidence, summer; highest ISS, autumn). Conclusion: The study shows a positive relationship between trauma occurrence and specific weather conditions, such as atmospheric temperature and pressure. There was a negative relationship between concentrations of PM2.5 or PM10, and trauma occurrence. However, no correlation was observed between weather conditions or the concentrations of air pollutants and ISS. In addition, seasonal, circaseptan, and circadian variations exist in trauma occurrence and severity. Thus, we suggest that evaluation of a larger, population-based data set is needed to further investigate and confirm these relationships.

Purpose: The purpose of this study was to investigate the association of job stress and health promotion behaviors with the quality of life in female riot police officers. Methods: A cross-sectional design was adopted, and a convenience sample of 182 female riot police officers from 5 Metropolitan Police Agencies in South Korea. All participants completed a self-administered survey questionnaire that assessed job stress, health promotion behavior, and quality of life in May 2018. The collected data were analyzed using t-test, analysis of variance, and correlation and multiple linear regression analyses, all of which were executed using SPSS/WIN 23.0 and STATA 13.0. Results: The level of job stress among participants was moderate, and the mean was 45.25 out of a maximum possible score of 100. The mean scores that emerged for health promotion behaviors and the quality of life were 2.62 (maximum=4) and 56.59 (maximum=100), respectively. Job stress (r=-.380, p<.001) and health promotion behaviors (r=.559, p<.001) were correlated with the quality of life. The statistically significant predictors of the quality of life were job stress (${\beta}=-.212$, p=.001) and health promotion behaviors (${\beta}=.417$, p<.001). Conclusion: The variables that were associated with the quality of life of female riot police officers were job stress and health promotion behaviors. Therefore, interventions that can enhance job stress management and health promotion behaviors are needed to improve the quality of life of female riot police officers.

Purpose: Aromatase inhibitors (AIs) are widely prescribed for postmenopausal women with breast cancer and are known to cause musculoskeletal pain. This study aimed to identify factors associated with AI continuation intention among breast cancer survivors (BCS). Methods: A cross-sectional survey was conducted on 123 BCS (stages I-III), who had been taking AIs for at least 6 weeks. Participants were recruited from a cancer center in Goyang, Korea, from September to November 2019. Descriptive statistics, Welch analysis of variance, Pearson correlation coefficients, and simple linear regression were used for the analysis. Results: Beliefs about endocrine therapy was a significant predictor of AI continuation intention (β=.66, p<.001). The majority of participants (87.0%) reported experiencing musculoskeletal pain since taking AIs and the score for the worst pain severity within 24 hours was 5.08±2.80 out of 10. Musculoskeletal pain, however, was not associated with AI continuation intention. Fear of cancer recurrence (FCR) was clinically significant (≥13) for 74.0% of the respondents (mean, 17.62±7.14). Musculoskeletal pain severity and pain interference were significantly associated with FCR (r=.21, p<.05; r=.35, p<.01, respectively). Pain interference was significantly associated with beliefs about endocrine therapy (r=-.18, p<.05). Conclusion: AI continuation intention can be modified by reinforcing patients' beliefs about endocrine therapy. Musculoskeletal pain may have a negative effect on beliefs about endocrine therapy and increase FCR among BCS. Thus, awareness of musculoskeletal pain during AI therapy should be raised and further research is required to develop multidisciplinary pain management strategies and clinical guidelines to reinforce beliefs about endocrine therapy.
