RESUMO
Despite the well evidenced health benefits of regular physical activity, many Iranian college students do not engage in physical activity sufficiently. The aim of this study was to assess cognitive factors related to regular physical activity in college students in Hormozgan University of Medical Sciences, Bandar Abbass, Iran. A total of 314 students from three schools of the Hormozgan University of Medical Sciences were selected randomly. Of the total number of students, 249 students filled out the questionnaires completely [response rate = 79.3%]. Exercise Benefits/Barriers scale, Selfefficacy scale, Exercise norms scale, and Planning for exercise scale were used to assess cognitive factors regarding physical activity; the Cronbach's alpha of these scales were 0.87, 0.83, 0.73, and 0.82, respectively. The mean age of participants was 21.7 +/- 2.7. Of all the participants, 46.2% were male. Only 26.5% [n = 66] were engaged in regular physical activity. Perceived barriers to exercise, selfefficacy to exercise, planning for exercise, and exercise norms had a significant relationship with physical activity [P < 0.05]. However, there was no significant relationship between perceived benefits to exercise and physical activity. For increasing physical activity in college students, self-efficacy and social support improvement is suggested
RESUMO
Surveying knowledge of nurses about HIV/AIDS can provide an evidence for designing appropriate educational program. This study aimed to investigate the knowledge of a sample of Iranian nurses about patients living with HIV/AIDS in Bandar Abbas, Iran. In this cross sectional study, 150 nurses completed two questionnaires, one dealing with demographic data and the other inquiring knowledge of nurses about HIV/AIDS based on existing instruments developed by Eckstein in 1987. The mean age of studied sample was 31.9 +/- 8.2 years. At the time of the study, 63.3% of the respondents had previously cared HIV-infected subjects. Most of the participants [99.3%] knew that drug abusers were at higher risk for HIV acquisition. Most of the participants [97.3%] also answered correctly that person with HIV could be asymptomatic but still infected. Finally, 29.3% thought that recapping used needles is a good way to prevent HIV infection. Those who had participated in educational program had higher overall scores of knowledge than non-participants [10.09 +/- 2.18 vs. 9.66 +/- 2.32, p=0.002]
