The effect of sexuality education based on the information, motivation, and behavioral skills model on improving the teachers' professional competence.

Introduction: Professional competence is the basic need of teachers in effective sexuality education. Therefore, the aim of this study was to evaluate the impact of school-based sexuality education (SBSE) on teachers' professional competence (TPC), using the information, motivation, and behavioral skills (IMB) model, in boys' schools. Methods: A randomized controlled field trial was conducted on 60 teachers who taught adolescents aged 11-19 years and were selected from 12 public boys' schools in Sari, northern Iran. Two groups (intervention and control) were assigned using a multi-stage stratified random sampling method. Researchers utilized a self-reported socio-demographic questionnaire and an IMB model-based questionnaire to assess the effects of the educational program. Four groups of 6-8 people underwent six 2-h training sessions based on an IBM model. Teachers were assessed before, immediately, and six weeks after the intervention to evaluate the outcome variables. The data were analyzed using the software SPSS-V19 and Chi-square test, Independent t-test, One-way ANOVA, and Repeated Measure ANOVA. Results: There were no significant differences between intervention and control groups at the baseline in socio-demographic characteristics and TPC (p > 0.05). The mean scores of TPC in sexuality education in every three dimensions of knowledge (P = 0.001), skill (P = 0.002), and attitude (P = 0.007) were significantly higher in the intervention group than in the control group. Conclusions: The results of this study show that by using the SBSE program based on the IMB model, the TPC for teaching sexual issues can be improved.

Exploring Sexual Life Experiences and Perceptions of Women with Diabetes: A Qualitative Study.

Background: Sexual life can be affected through different aspects of living with diabetes. This study aimed to explore the perception and experiences of Iranian women with diabetes at reproductive age regarding the impact of diabetes on their sexual life. Methods: This qualitative study was conducted from August 2018 to February 2019 in five diabetes centers in Tehran. Purposeful sampling method was used to select the participants, and data were collected by in-depth semi-structured interviews. Data were analyzed manually using the conventional content analysis method. Data saturation occurred after interviewing 24 women with diabetes. Results: Three themes were identified. The first theme was "diabetes-related threatened sexual life" with three categories: change in sexual functioning, negative sexual self-evaluation, and concern in sexual relationships. The second theme was "diabetes treatment challenges in sexual life," which included two categories: adverse effects of diabetes treatment in sexual life and the psychosocial distress related to diabetes treatment. "Couples' relationship adjustment to diabetes," was identified as the third theme, including four categories: the need for spouse's understanding of living with diabetes problems, perceived need for spouse's support, perceived need for intimacy, and the need to cope with diabetes-related childbearing challenges. Conclusion: According to the participants' perception and experiences, in addition to sexual problems, diabetes had affected their sexual life through diabetes treatment challenges in sexual life and the way the couples' relationships adjust to diabetes. Therefore, sexual problems screening and providing counseling services in community-based diabetes care planning are recommended.

How Do Iranian Men Perceive Their Sexual and Reproductive Health Situation? A Qualitative Content Analysis.

Background: Males' viewpoint about sexual and reproductive health (SRH) and their situation are essential components of men's and women's health in the community. Men have been overlooked in reproduction health, especially with reproductive issues such as contraception, sexually transmitted infections (STIs), infertility, and sexual function. This study aimed to investigate the males' perceptions of their SRH situation in Iran. Methods: A qualitative study was conducted from May 2016 to April 2017 on data retrieved through semi-structured interviews with 19 adult males aged 18 to 59 years. The participants were purposefully recruited from among populations of health centers in Alborz province, Iran. Conventional content analysis in OneNote software version 2016 was used for data analysis. Results: Three main themes and nine categories emerged including 1) Perceived SRH needs, including "need to increase men's awareness about SRH", "need to have an accessibility to SRH services", and "need to have a high-quality sexual relationship"; 2) perceived SRH responsibilities, including "health-seeking behaviors", "sexual skills", "childbearing responsibilities", and "ethical commitment", and 3) Men' perception of trends of social and cultural norms, including "changing SRH priorities" and "changing marital prototype". Conclusion: In this study, men perceived SRH as an important issue due to the changes in social and cultural trends, and many of their SRH needs have not yet been addressed. Hence, along with socio-economic changes, the policymakers of the health system should develop strategies and interventions to meet these needs.

Sexual quality of life and sexual self-efficacy among women during reproductive-menopausal transition stages and postmenopause: a comparative study.

Sexual self-efficacy is essential for appropriate and desirable sexual function and sexual quality of life. This study aimed to compare sexual quality of life and sexual self-efficacy among women during reproductive-menopausal transition stages and postmenopause. This was a cross-sectional study of a sample of Iranian women. The sexual quality of life-female (SQOL-F) scale was used to measure sexual quality of life (SQOL) and sexual self-efficacy (SSE) was measured using the sexual self-efficacy questionnaire (SSEQ). Data were compared between the study groups using multiple linear regression. In all 340 women (170 in reproductive-menopausal transition stages and 170 postmenopause) were studied. The mean ages of reproductive-menopausal transition stages and postmenopausal women was 30.8 ± 6.55 and 56.3 ± 3.54 respectively (P < 0.001). Sexual self-efficacy and sexual quality of life were found to be significantly higher in reproductive-menopausal transition stages compared with postmenopause women (P < 0.001 and P = 0.017 respectively). Sexual and relationship satisfaction and sexual repression subscales differed significantly between the two groups (P = 0.001 and P < 0.001 respectively). Higher sexual self-efficacy contributed to higher sexual quality of life (P < 0.0001). Reproductive-menopausal transition stages women appear to enjoy higher levels of sexual self-efficacy and sexual quality of life. Given the importance of sexual quality of life, it is recommended to pay greater attention to sexual self-efficacy among postmenopausal women in order to improve sexual quality of life in this population.

Development and validation of a guideline on sexual and reproductive health of breast cancer survivors in Iran: a mixed methods study protocol.

BACKGROUND: Sexual and reproductive health problems significantly decrease quality of life in survivors of breast cancer. The best approach is to provide services according to evidence-based guidelines developed based on their practical context. Here, we aim to develop and validate a guideline on the sexual and reproductive health of breast cancer survivors in Iran. METHODS: The guideline will be developed and validated using an exploratory sequential mixed methods approach in three phases: (1) describing sexual and reproductive health needs of survivors of breast cancer in Iran and the health services they receive in this regard, (2) performing a systematic review of existing guidelines, resources, and documents on the sexual and reproductive health of breast cancer survivors worldwide, and (3) developing and validating a guideline on the sexual and reproductive health of women who survived breast cancer in Iran based on the results of phases 1 and 2 through multiple steps. DISCUSSION: A comprehensive and practical guideline on the sexual and reproductive health of breast cancer survivors in Iran will be developed which will be compatible with their specific needs and culture, considering the limited resources available. This guideline can significantly improve the quality of life in breast cancer survivors in Iran. In addition, the approach we will use here can be utilized to develop guidelines on sexual and reproductive health of female cancer survivors in general.

Stakeholders' perspectives of comprehensive sexuality education in Iranian male adolescences.

BACKGROUND: A coherent sexuality education program for adolescents is part of their sexual and reproductive rights and can help them have a healthier future. Therefore, the aim of this study was to explore the perspectives and intervention preferences of Iranian stakeholders regarding comprehensive sexuality education (CSE) in male adolescents based on the IMB model (information, motivation, behavioral skills). METHODS: This study was a qualitative study that was analyzed through a directed content analysis approach. Individual interviews and focused group discussions (FGDs) were used for data collection. The data were collected through in-depth semi-structured interviews with stakeholders in two schools and the Education Department in Sari and the Ministry of Health and Ministry of Education in Tehran from March 2019 to August 2019. Data saturation was achieved after 28 interviews and 1 FGDs with 9 participants. Finally, two sets of data were coded and analyzed using directed content analysis. RESULTS: In this study, five themes emerged as (1) role of institutions; (2) role of organizations; (3) need for stakeholder's partnership; (4) need for adolescent sexuality socialization management; and (5) need for enhancing the teachers' professional competence, which seemed to influence the implementation of CSE in male adolescents. Participants also expressed a number of intervention preferences for CSE. The most important of these was the change in macro policies, helping to create a culture against all forms of violence and breaking the taboo of sexuality education for children and adolescents. CONCLUSIONS: The results of this study revealed the need for a CSE program for adolescents' sexuality socialization. The finding showed that teachers required training to enhance their professional competence about sexuality issues. Therefore, it is necessary to design and implement culture-appropriate skill based programs to enhance the teachers' professional competence regarding the adolescents' sexual health.

Association of depression with sexual function in women with history of recurrent pregnancy Loss: descriptive-correlational study in Tehran, Iran.

PURPOSE: The present study aimed to investigate the relationship between depression and sexual function in women with recurrent pregnancy loss. METHODS: In a cross-sectional correlational study, 130 consecutive patients with history of recurrent pregnancy loss were included who referred to Avicenna Fertility Center in Tehran, Iran during November 2018-February 2019. The outcomes were sexual dysfunction (Assessed with the Female Sexual Function Index) and depression (Evaluated with the Beck's Depression Inventory). The study data were analyzed by using Mann-Whitney and Kruskal-Wallis tests. RESULTS: The study findings revealed that 40.8% of the participants suffered from some degrees of depression. The data analysis revealed that depression had a significant inverse correlation with sexual function and its domains (r = - 0.392, p < 0.001, R2= 0.15). The spouse' education level and economic status demonstrated a significant relationship with women's sexual function (p = 0.01, p = 0.033). A significant relationship was also detected between women's depression and economic status (p = 0.028). CONCLUSIONS: The study findings showed that women with RPL who had severe depression indicated lower score of sexual function. Since psychological and sexual problems are not reported to health care providers due to giving priority to fertility issues or considering such issues as taboos, the assessment of sexual and mental health needs to be part of the consultation in women with history of RPL, whether the patient seeks help for depression and sexual dysfunction or not.

The titles of these chapters were selected based on the ethical considerations of various aspects of the field of regenerative medicine: (1) ethical principles of research on stem cells and regenerative medicine; (2) ethical considerations for research on stem cells (embryonic stem cells, epiblast stem cells, tissue-specific stem cells, stem cells derived from transdifferentiation, induced pluripotent stem cells [iPSCs], germline pluripotent stem cells, germline stem cells, and somatic cell nuclear transfer [SCNT] stem cells); (3) ethical considerations for research on somatic cells in regenerative medicine (adult somatic cells, fetal tissue somatic cells, and somatic cells derived from pregnancy products [other than fetus]); (4) ethical considerations for research on gametes in regenerative medicine; (5) ethical considerations for research related to genetic manipulation (human and animal) in regenerative medicine; (6) ethical considerations for research on tissue engineering in regenerative medicine; (7) ethical considerations for pre-clinical studies in regenerative medicine; (8) ethical considerations for clinical trials in regenerative medicine; (9) ethical considerations for stem cells and regenerative medicine bio-banks; (10) ethical considerations for privacy and confidentiality; and (11) ethical considerations for obtaining informed consent. CONCLUSION: This article discusses the process of developing the present ethical guidelines and its practical points. We hope that it can play an important worldwide role in advancing ethics of research on stem cells and regenerative medicine.

Evaluation of effectiveness of a sexuality education program for parents of male adolescents: promoting of parent-adolescent sexual communication.

OBJECTIVES: Parents play a significant role in promoting of healthy sexuality in adolescents. The purpose of the present study was to assess the effectiveness of a sexuality education intervention program to enhance parent-adolescent sexual communication. METHODS: This study was a randomized controlled field trial. Parents of male adolescent aged 13-16 years were recruited from eight public all-boys high schools in Karaj, Iran. A multi-stage stratified random sampling method was used and 102 parents were assigned into intervention and control groups. The recruitment and data collection process lasted from February to November 2019. Self-report demographic questionnaire and six general parenting and parent-adolescent sexual communication measures were used to assess the impact of intervention. Sexuality education program was presented for the parents of intervention group, in the form of four weekly 2-h sessions. Parents were assessed at the baseline, within one week post-intervention, and three-month follow-up to evaluate the outcome variables. The data were analyzed using the Chi-square test, two-sample t-test, general linear model analyses, and Bonferroni test. RESULTS: In terms of parent-adolescent general communication, parental monitoring, parent-adolescent communication about sex-related topics, parent's sexual communication skills, parent's self-efficacy, and responsiveness to sexual communication. There were no significant differences between intervention and control groups at the baseline (p>0.05). Compared to controls, intervention parents reported more improvement in general communication across the time; however, significant differences were not observed regarding general communication and parental monitoring (p=0.94, p=0.95). Parents in the intervention group significantly differed from those in the control group for the mean scores of parent-adolescent communication about sex-related topics (p=0.04), parent's sexual communication skills (p=0.04), parent's self-efficacy (p=0.002), and responsiveness (p<0.001) to sexual communication at each follow-up. CONCLUSIONS: We identified the educational program as a promising tool for improving parent-adolescent communication regarding sexuality-related issues. This program provides the evidence for implementation of parent-based sexuality education programs.

Concerns and educational needs of Iranian parents regarding the sexual health of their male adolescents: a qualitative study.

BACKGROUND: Parents play an important role in promoting the sexual health of their adolescents. However, many parents experience several challenges. The purpose of this study was to explore the concerns and educational needs of Iranian parents regarding the sexual health of their male adolescents. METHODS: This qualitative study was designed based on the conventional content analysis approach. Semi-structured and in-depth interviews were conducted with 16 parents of male adolescents aged 12-18 years. All interviews were audio recorded and transcribed verbatim. The data were collected through purposeful sampling and continued until data saturation. Finally, the Graneheim and Landman strategies were used to analyze data. RESULTS: According to the participants' comments, four main categories were extracted as follows: fear of emotional and sexual harms, quality of parent-child relationships, effect of media and cyberspace, and necessity of sexuality health education. CONCLUSIONS: The findings highlighted the need for sexuality health education through cooperation with schools for offering appropriate education to the students, parents, and school staffs. The results showed that parents required training to enhance their knowledge and skills to improve their communication with their adolescents about sexuality issues. Therefore, it is necessary to design, implement, and evaluate culture-appropriate educational programs to address the parents' concerns regarding adolescents' sexual health.

The Social Construction of Infertility Among Iranian Infertile Women: A Qualitative Study.

BACKGROUND: Infertility is considered an important phenomenon in couples' life. Infertility and its treatment process influence all aspects of the individual's life. This study aimed to explain the psycho-social process of social construction of infertility among Iranian infertile women. METHODS: This was a qualitative study using a grounded theory approach. The study setting was the Vali-e-Asr Fertility Health Research Center and Avicenna Fertility clinic in Tehran. The sampling started purposefully and it was continued theoretically. The data collection was performed by using 36 semi-structured interviews, observation and field notes with 27 women who suffered from primary and secondary infertility having no living child. The method suggested by Strauss and Corbin was used for data analysis. RESULTS: Results indicate that "Concerns over life instability" and "being judged by others" were the participants' most important preoccupation. Attempts to stabilize life and get rid of being judged by others were key aspects of the social construction of infertility and the main strategies for resolving their preoccupation. This core concept explained the basic psychological-social process of infertility in relation to axial codes. CONCLUSION: The results of the study show that various interactive factors affect the social construction of infertility among infertile women who focus on the central concept of attempts to stabilize life and get rid of being judged by others. Therefore, in order to achieve this goal, infertile women should be empowered by effective coping strategies.

The Effect of Counseling Based on Sexual Self-Concept via Social Networks on Smartphone in Infertile Women: A Randomized Controlled Trial.

BACKGROUND: Infertility can affect the physical, mental and emotional aspects of a person's life. This study aimed to investigate the effect of sexual counseling via social networks on Smartphone in sexual self-concept of infertile women. METHODS: In a randomized controlled trial, 80 eligible infertile women referred to the fertility centers of Alborz University of Medical Sciences from April to July 2018. They were randomly assigned into intervention) sexual counseling with routine infertility counseling) and control groups )routine infertility counseling(. Eight counseling sessions via social networks were held for both groups. The Snell's sexual self-concept questionnaire was completed by participants before and after the intervention. The data were analyzed using SPSS 19 with a significance level of P<0.05. RESULTS: The mean age of women was 30.76±0.72 years and the most infertility duration was more than 36 months. The results of a repeated measure showed that there were significant differences in positive self-concept domain between the two groups during the time by comparing the means (120.4±17.9 versus 105.1±16.8). We also found an increasing trend of the scores in positive sexual self-concept domain (110.6±18.42, 120.1±18.7, 120.4±17.9) (P<0.001) and a decrease in negative sexual self-concept domain (24.3±7.87, 20.2±7.77, 19.65±6.97) (P<0.001) in intervention group. In the situational self-concept, there were no difference between the two groups during the time (P=0.06). CONCLUSION: The results obtained in the present study showed that counseling through social networks was effective in improving the sexual self-concept in infertile women, thus ameliorating the couples' sexual relations. Trial Registration Number: IRCT20160503027728N9.

Sexual Behaviors and Its Predictors among Iranian Women Living in Kashan City 2017: A Cross-Sectional Study.

BACHGROUND: Women's sexual well-being has been the center of attention in the field of sexology. Study of sexual behavior and investigating its predictors are important for women's health promotion. This study aimed to explore the components of women's sexual behaviors and their possible associations with demographic variables. MATERIALS AND METHODS: This study was a cross-sectional study (descriptive and analytic) that was conducted in Kashan city, Iran. A National Sexual Behavior Assessment Questionnaire was completed by 500 women of 15 to 49 who referred to the public health centers. To analyze the data, R software was used, ANOVA or Kruskal-Wallis (for parametric or nonparametric data, respectively) were used to compare outcomes among different groups. In order to evaluate the correlation between the subscales, the Pearson correlation coefficient was used. RESULTS: From all participants, 31.8% obtained high scores in the sexual capacity, 21.2% had high scores in sexual motivation and 0.2% had high scores in sexual function. In sexual script component, 86.2% of women who held traditional beliefs toward sexual behaviors; the majority (91.5%) of women believed in mutual and relational sexuality, 83.4% believed in androcentricity (male-dominated sexuality). Pearson correlation test showed a significant positive correlation between sexual capacity, motivation, function and sexual script. Linear Regression model showed that sexual capacity is associated with women's education and age of her spouse. Sexual function and sexual motivation were significantly associated with the age of subjects' spouses. CONCLUSION: In this study, subjects had low scores in sexual performance while higher scores were achieved in sexual capacity and motivation. This discrepancy can be attributed to the role of sexual scripts dominating the participants' sexual interactions in this study. We suggest gender-specific and culturally-sensitive education should become a part of women's health programs in Iran.

Effect of Sexual Education on Sexual Function of Iranian Couples During Pregnancy: A Quasi Experimental Study.

BACKGROUND: The aim of this study was to evaluate the impact of husbands' participation in sexual education on sexual function during pregnancy. METHODS: This quasi experimental study was conducted on 123 couples who were divided in two intervention (A: couples, B: pregnant women) and one control (C) groups. Group A couples received sex education, Group B women received sex education without their spouses, and Group C women received routine prenatal care without sex education. Sexual functions of couples were assessed by Female Sexual Function Index (FSFI) and International Index Erectile Function (IIEF) questionnaires, before sex education, four weeks after the intervention, at the end of the second trimester and at the end of the third trimester. RESULTS: Mean total scores of FSFI and IIEF were not different at baseline in three groups. Repeated measure analysis showed significant differences between groups (A and B with C) in the mean total scores of FSFI and IIEF during the third trimester. The mean total scores of the two intervention groups of A and B were not significant. CONCLUSION: According to the results of the present study, promoting the sexual function of pregnant women needs to include the sex education on prenatal care. Whereas spouses' participation was suggested to have a great role in the effectiveness and strengthening of the education in various studies, this study showed that the lack of spouses' participation for whatever reasons may lead to the same results of previous studies which emphasized the necessity of spouses' participation.

Development and psychometric evaluation of the sexual knowledge and attitudes scale for premarital couples (SKAS-PC): An exploratory mixed method study.

BACKGROUND: Designing a valid and reliable questionnaire that allows a fair evaluation of sexual knowledge and attitudes and develop a proper sexual educational program is necessary. OBJECTIVE: The present study was designed to develop and psychometric evaluation of the sexual knowledge and attitudes scale for premarital couples. MATERIALS AND METHODS: An exploratory mixed method study was conducted in two phases; in the first, in order to develop a questionnaire an item pool was generated on sexual knowledge and attitudes through focus group discussions and individual interviews. In the second phase, the psychometric properties of the questionnaire were examined. For this purpose, face validity, content validity as well as construct validity were conducted. Reliability was assessed by the Cronbach's alpha coefficient to assess internal consistency and test-retest reliability. RESULTS: In the first phase an item pool with 88 questions was generated (sexual knowledge 45 items and sexual attitudes 43 items). In the second phase, the number of final items reduced to 33 and 34 items of sexual knowledge and sexual attitudes respectively, through exploratory factor analysis (EFA). Five factors for sexual knowledge and six factors for sexual attitudes identified by EFA. The Cronbach's alpha coefficient for two sections was 0.84 and 0.81 respectively. The test- retest correlations for sexual knowledge and sexual attitude was 0.74 and 0.82 respectively. CONCLUSION: The findings suggest that the Sexual Knowledge and Attitudes Scale for Premarital Couples is a valid and reliable instrument. Further studies are needed to establish stronger psychometric properties for the questionnaire.

Sexual Life During Pregnancy: Effect of an Educational Intervention on the Sexuality of Iranian Couples: A Quasiexperimental Study.

The sexual life of couples and their needs during pregnancy receive little attention in practice. The aim of this study was to evaluate an educational intervention delivered to pregnant couples to improve their sexual function and satisfaction. This quasiexperimental study was conducted on 128 couples, allocated into two groups of intervention (group A: couples, group B: pregnant women) and one control group (C). Postintervention, the mean of the total score of sexual function and satisfaction of the couples was significantly higher in the intervention groups compared with the control group (p < 0.05). It seems sexuality education specific for prenatal care would be effective.

CONCLUSION: Most participants emphasized the necessity of sexual health education not only because of medical concerns, but also from the perspective of social issues. Providing these services should be considered a priority.

Public sexual health promotion interventions and strategies: A qualitative study.

INTRODUCTION: Sexual health promotion is the process of enabling people to increase control over their sexual health that should be based on people's needs and abilities. The aim of this study was to explore public sexual health promotion interventions and strategies. METHODS: This study was a qualitative content analysis approach. This qualitative study was a qualitative part of an exploratory sequential qualitative-quantitative study that took place between November 2014 and May 2015 and was conducted in Rasht, Iran. Data were collected using semi-structured interviews with 38 engaged and married men and women as well as nine key informants. The data were analyzed by the content analysis method and by using qualitative data analysis software MAXqda 2011. RESULTS: Analyzing participants' perspectives and experiences revealed two main categories, i.e., 1) General actions to promote sexual health (with three sub-categories: public policies promoting sexual health, development of sexual health supporting environments, and removal of barriers to receiving services) and 2) Specific actions in the current health system (with three sub-categories: economic policy, empowering individuals and the society, and reviewing the current health system). CONCLUSIONS: General actions (public policies, supporting environments developed, and removal of barriers to receiving services) and integration of specific actions in the health system, such as empowering individuals' needs for promoting sexual health. Achieving these goals necessitates the review of the current health system in Iran.

Psychometric properties of KIDSCREEN health-related quality of life questionnaire in Iranian adolescents.

INTRODUCTION: Health-related quality of life (HRQOL), which is receiving increasing attention, is a multidimensional concept that encompasses different areas including the physiological, psychological, social, and spiritual aspects of life. The KIDSCREEN-52 questionnaire is designed to measure the HRQOL of 8-18-year-old children and adolescents. The aim of this study was to develop a Persian version of KIDSCREEN-52 and analyze the validity and reliability of the translated version. METHOD: The KIDSCREEN-52 was translated into Persian in keeping with the international cross-cultural translation guidelines. A cross-sectional study was performed in the city of Tehran during 2012-2013. 328 students ranging in age from 8 to 18 years were enrolled in the study. The reliability for each dimension was estimated using Cronbach's alpha coefficient. To examine the validity of the questionnaire, a confirmatory factor analysis (CFA) was conducted. RESULTS: The Cronbach's alpha coefficient was higher than 0.7 in all ten dimensions except self-perception. Validity of this questionnaire was confirmed by CFA. (Relative chi square (χ (2)/df) = 1.73; root-mean-square error of approximation = 0.047; normed fit index = 0.93; Tucker-Lewis index = 0.97; comparative fit index = 0.97; and relative fit index = 0.92.) CONCLUSION: The Persian version of KIDSCREEN-52 is reliable and valid and can be used as a self-administered instrument for measuring HRQOL in children and adolescents in Iran.

Air pollution: the knowledge and ideas of students in Tehran-Iran, and a comparison with other countries.

Study of students' knowledge about air pollution can help authorities to have better imagination of this critical environmental problem. This research examines guidance school and high school students' ideas about air pollution and the results may be useful for the respective authorities to improve cultural and educational aspects of next generation. In this cross-sectional study, a closed questionnaire was used to examine knowledge and ideas of 2140 randomly selected school students of Tehran-Iran about composition of unpolluted air, air pollution and its causes and consequences. Cognitive scores were also calculated. Outcomes were compared with results of similar researches in Australia, Hong Kong and the United Kingdom. While a student's 'cognitive score' could range from -16 to +16, Iranian students' mean cognitive score was equal to +2.97. There was not significant statistical difference between girls and boys (P=0.32). In response to question "most common gas in unpolluted air" nitrogen was mentioned by only 23.7%, While 45.1% of students mentioned oxygen. In general, student's knowledge was not acceptable and there were some misconceptions such as "supposing oxygen as the most prevalent gas in unpolluted air". The findings of this survey indicate that, this important stratum of society of Iran have been received no sufficient and efficient education and sensitization on this matter.
