  • The purpose of this study was to examine the level of concern and the level of knowledge of endocrine disruptors, and the level of dietary behaviors to decrease exposure to endocrine disruptors, to determine the factors affecting the level of knowledge and behaviors, and to assess the causal relationship between them. The data were collected from 579 adults in Seoul, Incheon, Daejeon, Daegu, Busan and Gwangju provinces. Frequencies, t tests, analysis of variance, Cronbach's alpha, Pearson's correlation coefficient analysis, multiple regression analyses, and path analysis were carried out by SPSS for Win V.18.0. The results of this study were as follows: The level of concern about endocrine disruptors was higher than the medium level. The respondents were most concerned about a container of cup ramen among products related to foods. The levels of both knowledge and behaviors in order to decrease exposure to endocrine disruptors in dietary life were not high. The factors affecting the level of knowledge of endocrine disruptors were educational level, attendance in education for endocrine disruptors, and concern about endocrine disruptors. On the other hand, sex, age, concern about endocrine disruptors, and the level of knowledge of endocrine disruptors affected the level of behaviors to decrease exposure toward endocrine disruptors. The results of the path analysis showed that educational level and education of endocrine disruptors had an indirect influence on the level of behaviors in order to decrease exposure to endocrine disruptors in dietary life. The concern about endocrine disruptors had both a direct and an indirect effect on the level of behaviors to decrease exposure to endocrine disruptors in dietary life. In addition, sex, age and the level of knowledge of endocrine disruptors directly affected the level of behaviors to decrease exposure to endocrine disruptors in dietary life.

  • The purpose of this study was to investigate the cognition of high school students and science teachers on the endocrine disruptors. Subjects of this study were 204 high school students and 26 science teachers. The results were as follows. Students obtained informations about endocrine disruptors mainly through mass media like TV, radio or lesson in school. Most of them were interested in endocrine disruptors and they thought that endocrine disruptors were very dangerous for people. And they preferred learning materials such as movies, images, and animations, but they didn't want to participate in activity of education on endocrine disruptors actively. Science teachers has agreed to needs of education on endocrine disruptors and has required education programs such as movies, images or animations for effective endocrine disruptors education.

  • Recently, endocnne dIsruptors have been known as one of the most harrnful chemical material. The purpose of this study is to investigate the cogintion and behavoor of milddle school students on the endocrine disruptors. To achieve this goal, survey research was conducted. Data were collected from 531 first and third-grade students in Suwon city. The main results of this study are summarized as follows FIrst, the mam source of information on the endocrine disruptors was mass media such as TV. This means environmental education in school is needed and mass media can be a very important tool for education. Secondly, as grades become higher, more students had knowledge on the endocrine disruptors. The difference between boys and girls was not significant. Thirdly, most students recognized endocrine disruptors as a dangerous material. However, they had an optimistic view on the possibility of resolving the environmental problems using science and technology in the future. Lastly, the scores of environmentally sound behavior was not highly correlated to those of knowledge. This means that in current environmental education system, more knowledge on the endocrine disruptors do not ensure more environmentally-correct behavior. These survey results show that environmental education on the endocrine disruptors should be constructed to induce correct behavior. That is, environmental education from now on has to be conducted to change the behavior of student as well as to increase knowledge.

  • Purpose: This study was conducted to examine the pro-environmental attitude (actual commitment domain, verbal commitment domain, affect domain), behavior to decreased exposure and knowledge of endocrine disruptors by obesity -related profiles (BMI, body fat percentage, visceral fat percentage, skeletal muscle mass percentage, waist circumference, waist-hip ratio). Methods: A cross-sectional study was conducted with 102 nursing students. Data were collected from November to December, 2015 using self-report questionnaires and physical measurements. Data were analyzed using t-test, Pearson correlation and coefficients with SPSS 18.0. Results: The study results showed that actual commitment domain of pro-environmental attitude and behavior to decreased exposure level on endocrine disruptors were significantly related to visceral fat percentage. Actual commitment domain of a pro-environmental attitude was significantly related to body fat percentage. Pro-environmental attitude was significantly related to the behavior to decreased exposure level on endocrine disruptors and knowledge thereof. Conclusion: These findings suggest that visceral fat and body fat percentages were significantly related to the actual commitment domain of a pro-environmental attitude. Therefore, a replication study is recommended to understand the connection between endocrine disruptors and obesity. In addition, developing an education program about endocrine disruptors for nursing students is recommended. In particular, a pro-environmental attitude, especially on actual commitment domain, could be involved as an education program.

  • The term endocrine disruptors is used to describe a variety of natural and manmade substances that have the capacity to potentially interfere with and modify the normal physiology of endocrine system either by mimicking, blocking or modulating the actions of natural endogenous hormones. The rising incidence of breast cancer over the last 50 years and the documented higher incidence in urban as compared to rural areas suggest a relationship to the introduction and increased use of xenoestrogens in our environment. The literature has developed over the last decades where initial experiments on endocrine disruptors did not support an involvement in breast cancer, and then evidence mounted implicating various environmental factors including hormones, endocrine disrupting chemicals and non-endocrine disrupting environmental carcinogens in the pathogenesis of breast cancer. Available data support the hypothesis that exposure to endocrine disruptors in utero leaves a signature on mammary gland morphogenesis so that the resulting dysgenic gland becomes more predisposed to develop tumors upon exposures to additional insults later on during life. Exceptionally, exposure to phytoestrogens could be beneficial to human health. Most of the available data are from well developed countries while the developing countries are still understudied regarding these issues. Here, we raise a note of caution about potential role of environmental toxins including endocrine disruptors in breast cancer development and call for serious measures to be taken by all involved parties in the developing world.

  • Relationships between accumulations of endocrine disruptors and abnormalities in the reproductive organs in the adult male striped field mice, Apodemus agrarius, were reviewed. High levels of phenolic compounds were detected in the mice collected at an agricultural village in Gaduck island and at a place having a sewage problem in Samdong-myeon, Namhae. High levels of organo tin compounds were found in the mice collected at Jiri Mt. a tourist resort. Considerably high levels of phenolic or organo tin compounds were detected in mice with shrunken reproductive organs accounting for 14∼42% of the mice examined in each area, which suggests that the abnormality of reproductive organs may be induced by the endocrine disruptors. This hypothesis is strongly supported by histological observations of shrunken reproductive organs, such as necrosis of testicular germ and epithelial cells. This was found not only in the mice with shrunken reproductive organs but also in the mice with enlarged reproductive organs, both had accumulated high levels of endocrine disruptors in general.
