The purpose of this research is to understand physical activity of clinical nurses, and the affecting circumstance of personal background factors and social psychological factors on physical activity. The research utilized the cross-sectional design, to base on nurses of Taipei Municipal Hospital as the research samples. The study utilized randomly-selected sampling, to totally issue 400 copies of questionnaire, retrieving 360 copies, with 300 copies of effective questionnaire. The effective retrieving ratio is 75%. Data analyses include Pearson product-moment correlation, t-test, one-way ANOVA, stepwise regression analyses. The main results are shown as followed:
1. Energy expenditure of physical activity during the weekday is higher than energy expenditure of the physical activity on the weekend day. Physical activity is insufficient on the weekend day. Energy expenditure of physical activity during the weekday is 55.8kcal/kg/day, moderate and vigorous physical activity is 15.0kcal/kg/day; physical activity on weekend day is 43.0kcal/kg/day, moderate and vigorous physical activity is 4.6kcal/kg/day; the average of physical activity on both weekday and weekend day is 47.2kcal/kg/day, the average of moderate and vigorous physical activity is 8.0kcal/kg/day.
2. The personal background factors with regards to the perceived benefits of exercise or perceived barriers to exercise has not achieve significant difference, age and professional position are the factors that affect self-efficacy for exercise, from which the age group of 30 to 39, registered professional nurses, and nurses with regards to exercise has lower level of self-efficacy.
3. The personal background factors that affect energy expenditure of physical activity are the work shift, educational level, and marital status, those who needs to take turn for three shifts, those of vocational high school, junior college, and those who are married, have higher energy expenditure of physical activity. The factors that affect moderate and vigorous physical activity are the work shift, work unit, professional position and educational level.
4. The correlation of social psychological factors and physical activity, the self-efficacy for exercise is the most significant. Moderate and vigorous physical activity on weekend day has received greater affect by the perceived barriers to exercise. Yet, perceived benefits have no significant in correlating with regards to physical activity.
5. The research object has higher level of perceived benefits of exercise, believing that exercise can enhance blood circulation, enhancing physical health, increasing flexibility and promoting metabolism, strengthening physical fitness, and maintaining youthfulness through benefits of exercise, which have all scored the highest.
6. The perceived barriers to exercise of the research object belongs to moderate level, the factor of barrier is mostly because of slacking off, insufficient time, bad weather, heavy work loading, needing of work shift, bad health condition and not enough physical strength.
7. The self-efficacy of the research object is in low to middle level, which has lower degree of self-efficacy for exercise with heavy work loading, bad health condition, slacking off, insufficient time, insufficient physical fitness, the necessary of family care, bad weather, and work shift.
8. Work shift, self-efficacy for exercise and marital status are the important predicted variance of weekday’s physical activity, these three variables can be explained as 10% of the variation of physical activity. Self-efficacy for exercise, marital status, and educational level are the important predicted variances for physical activity on the weekend day and the average of the weekday and weekend day, which can be explained as 8.7% of the variation of physical activity for the weekend day, 11.4% of the variation of physical activity during the average of the weekday and weekend day. In moderate and vigorous physical activity, the most important affecting factor are work shift, then self-efficacy for exercise, these two variance can be explained as 8.3% of the variation, the factors that affecting the moderate and vigorous physical activity on the weekend day are self-efficacy for exercise and marital status. These two variables can be explained as 7.1% of the variation. The average of moderate and vigorous physical activity on the weekday and weekend day, is based on the affect of self-efficacy for exercise, work shift and educational level as the most significant, these three variances can be explained as 9.9% of the variation.
