Background & Aim: Youths are the most at risk group for HIV/AIDS in the world and education of the preventive measurements is the most effective way for decreasing the incidence of HIV/AIDS among them. Due to ever-increasing cases of HIV and the importance of education, we compared the effects of three educational methods (peer education, education by physician and giving pamphlets) on knowledge of female high school students&apos of Kerman shah on HIV/AIDS.

Methods & Materials: One thousand and five hundred female third grade students were recruited from 21 high schools using stratified random sampling method. An average of 73 students were selected from each school and participated in a pre-test exam using a questionnaire. Of 1500 students, 498 and 502 students were taught by general practitioners and peers, respectively. Pamphlets were presented to 500 other students. Twenty days after the educational intervention, the participants were contributed in a post-test exam using the very questionnaire. Data were analyzed using descriptive and inferential statistics via SPSS version 11.5.

Results: The students&apos mean age was 16.78 (SD=0.7). The mean scores of pretests and post-tests in all 3 groups were significantly different (P<0.001). The mean score for the group taught by general practitioners (10.7±3.6) was higher than the scores of other two group scores (8.8±3.4 and 7.3±3.9, respectively for peer education and pamphlet groups) after the interventions. Bonferroni statistical test showed the significant difference (P<0.001).

Conclusion: Education presented by general practitioners seems to be more effective than the other two ways in increasing students&apos knowledge about HIV/AIDS.

Background & Objective: Regular and adequate physical activity is a major factor in maintaining good health throughout entire life course. Levels of inactivity are high in all countries. Effective educational interventions are needed to promote physical activity in all populations. The aim of this study was to determine the effect of a heath education intervention on physical activity knowledge, attitude, and behavior in health volunteers of Tehran in 2008.

Methods & Materials: All active female health volunteers of Tehran, district 14 (n=100) were recruited for this experimental study. Data were gathered using a questionnaire of knowledge, attitude, and behavior regarding physical activity. The questionnaire was completed by all participants in two phases of pre- and post-intervention (four weeks after the intervention). Health education intervention strategies were presented to the intervention group during three educational sessions with one week interval between the sessions. Data were analyzed using related statistical tests.

Results: Findings showed significant statistical differences in knowledge, total physical activity rate per week, and the mean sitting time per day between the control and intervention groups after the intervention (P<0.05). While, these variables were not significantly different before the educational intervention among both groups.

Conclusion: The health education intervention presented in this study was effective in promoting knowledge, total physical activity rate per week, and mean sitting time per day among the female health volunteers.

Background & Aim: Menstrual health is an important aspect of adolescent health. Most girls do not have proper information about menstrual health, and incorrect information from unreliable sources makes problems for them. Aim of this study was to compare small group-based education with maternal participation and routine education on adolescent girls’ menstrual health behaviors.
Methods & Materials: This randomized clinical trial study was performed on 60 high school students with regular menstruation in the groups of intervention and control. Among high schools in Mashhad in 2018, two schools were assigned to one of two groups by lottery. Menstrual health education was provided to the intervention group in four sessions as the groups of 3-4 people. For mothers in this group, two 2-hour sessions with the same content were held and the students in control group received routine education. Data were collected by a questionnaire on menstrual health behaviors, before the intervention, after the end of the first and second menstrual cycle. Data were analyzed by Mann-Whitney, Chi square and independent samples t-test using the SPSS software version 16.
Results: before the intervention, there was a statistically significant difference in the menstrual health behaviors score (P=0.199). After the intervention, mean score of menstrual health behaviors (the end of the first and second menstrual cycles) significantly increased (P<0.001) for the two groups. Also, mean score of menstrual health behaviors for the intervention group was significantly higher than that of for the control group (P<0.001).
Conclusion: The small group-based education with the participation of mothers in comparison to routine education was more effective in promoting menstrual health behaviors in adolescent girls. This method is recommended to health planners for education of health issues, including menstrual health.
