Association between Maximum Aerobic Power and General Health in Women

Background: The highest aerobic capacity (VO2max) is one of the criteria that can be used to create a balance between work and worker. To maintain the health and physical capacity of individuals, as well as to increase production and profitability, physical work capacity (PWC) can be used to put individuals in jobs proportional to their capacities. Methods: This cross-sectional study was performed on 120 women working in hospitals aged 21-49 years old. Individuals were evaluated by a single-stage Ebbeling test. A questionnaire about general health, job fatigue and job satisfaction was used, along with a treadmill. Data were analyzed by SPSS V22 software using the Pearson correlation and t-test. Results: According to the results, the highest aerobic capacity, physical working capacity and general health were  ml/kg body weight per minute,  kcal/min and  respectively, and mean and standard deviation of fatigue and job satisfaction scores were  and  respectively. In this study, there was a significant relationship between VO2max and age, weight, body mass index (BMI), fatigue and job satisfaction. Conclusion: According to the results, since fatigue and job satisfaction are related to workers' VO2max, it is recommended that, in addition to considering the aspects of physical fitness in the workplace, special attention should be paid to mental aspects, since they affect the physical and, consequently, the productivity of workers

Validity and Reliability of Knowledge, Attitude and Behavior Assessment Tool Among Vulnerable Women Concerning Sexually Transmitted Diseases

Objective: The study aimed to design and evaluate the content and face validity, and reliability of knowledge, attitude, and behavior questionnaire on preventive behaviors among vulnerable women concerning sexually transmitted diseases (STDs). Materials and methods: This cross-sectional study was carried out in two phases of an action research. In the first phase, to explain STDs preventive domains, 20 semi- structured interviews were conducted with the vulnerable women, residing at women prison and women referred to counseling centers. After analyzing content of interviews, three domains were identified: improve their knowledge, modify their attitude and change their behaviors. In the second phase, the questionnaire was designed and tested in a pilot study. Then, its content validity was evaluated. Face validity and reliability of the questionnaire were assessed by test re- test method and Cronbach alpha respectively. Results: Index of content validity in each three domain of the questionnaire (knowledge, attitude and behavior concerning STDs) was obtained over 0.6. Overall content validity index was 0.86 in all three domains of the questionnaire. The Cronbach’s alpha as reliability of questionnaire was 0.80 for knowledge, 0.79 for attitude and 0.85 for behavior. Conclusion: The results showed that the designed questionnaire was a valid and reliable tool to measure knowledge, attitude and behavior of vulnerable women, predisposed to risk of STDs
