Cancer is increasingly being seen as a disease that is preventable and manageable. Knowledge often does constitute one element in the behavior change process. In addition, to promote the cancer prevention programs, data on level of knowledge among the target population are needed. The present research (as the first) aimed at providing information on level and correlates of awareness of cancer risk factors among the general public in Iran. The level of knowledge about 12 cancer risk factors (as a section of a multipart questionnaire) was assessed in a representative sample of 2500 adults (aged >18 years) in Tehran, Iran. The data were analyzed using latent class regression with the R statistical package. A small proportion of the respondents (12.2%) had high knowledge level and most of them had mixed (56.9%) and low level of awareness (30.9%). The most important determinants of knowledge level included level of education, gender, and family history. The results provided valuable clues and guidelines toward the formulation of relevant cancer prevention strategies, especially within the scope of health education. The applied statistical model presented a new descriptive and analytical perspective to evaluate the level of knowledge about the cancer risk factors and its determinants.

The aim of this study was to investigate women s knowledge about and attitude toward emergency contraception (EC) in women who referred to health centers of Tehran University of Medical Science. The subjects in this study consisted of 250 married women of fertility age who had been selected randomly and interviewed by the researcher. The majority of the subjects had not used EC. Just 5.2% (13 women) had used this method and 8.31% had knowledge and information about EC. There was a significant correlation between knowledge about and use of this method (p = 0.0001). Although the users of this method were more knowledgeable about EC than nonusers, a majority of subjects (76.57%) had a positive attitude toward EC; however, there was not a significant correlation between positive attitude and use of EC (p = 0.184).

The explanatory model of diabetes management might help health care providers to understand the circumstances that may influence patients' self-care behaviors. This acquaintance can lead to a better assessment and restored services in diabetes management. Background:Managing diabetes requires changes in the patients' life style and health habits which in turn need the comprehensive understanding of the disease and its impact. Objectives: To understand the explanatory model of diabetes in Iran, a qualitative study was performed using the grounded theory method. Patients and Methods: Thirty persons were interviewed: fifteen patients, eleven nurses, three physicians and one dietitian. The semi-structured interviews were transcribed and analyzed in three stages of open, axial and selective coding. Results: The findings showed that patients' personality can shape their self-care behavior; however, curing, caring and supporting systems are also necessary. The interactions between personality, curing, caring and supporting systems and society makes the outcome, which is the core variable in the designed explanatory model of diabetes. Conclusions: This paper reflects an explanatory model of diabetes management. Understanding the factors that affect self-management behavior is important for nurses as key providers in the health care system.Published by Kowsar Corp, 2012. cc 3.0.
