Background and Aim: Based on WHO reports, there are about 100-150 million people with asthma around the world and the number is increasing. Asthma is a prevalent disease and permanent self-management is needed in order to control the symptoms and maintain the normal action of the lungs and a normal level of activity. The Green's Model of Health Education Planning provides a systematic process for planning, implementation and evaluation of population health promotion programs and is used in a broad range of issues in health promotion, including self-management in asthma. This study was carried out with the aim of determining predictors of self-management behaviors in patients with asthma in Yazd, Iran, based on the above-mentioned model.

Methods and Materials: In this cross-sectional study convenience sampling was employed to recruit 94 outpatients with asthma from among those referring to Shaheed-Sadooghi Clinic in Yazd, Iran. Data were collected using a questionnaire based on the Green's Model constructs, consisting of predisposing, reinforcing, and enabling factors and self-management behaviors. Reliability and validity of the questionnaire were assessed prior to data collection.

Results: The subjects acquired 49.5%, 68.6%, 67.3%, and 61.2 % of the earnable scores for self-management behavior, predisposing factors, reinforcing factors, and enabling factors, respectively. Predisposing, reinforcing, and enabling variables had positive correlations with self-management behaviors (p<0.01) and accounted for 34.6% of the self-management variance. Predisposing factors were the strongest predictor (β = 0.480).

Conclusion: It is concluded that the Green's Model of Health Education Planning can be used in developing countries, such as Iran, as a framework for planning intervention programs in an attempt to improve the self-management behaviors of patients with asthma. Designing and implementing educational programs aiming at promoting self-management behaviors in asthmatic patients with emphasis on predisposing factor enhancement is recommended.

Background and Aim: This paper reports on the predictors of high school students' oral health behaviors (OHBs) based on the Pender's Health Promotion Model (HPM) in an attempt to identify effective factors that may be addressed through intervention efforts.

Materials and Methods: A multistage cluster sample of 403 high school students were recruited from 8 high schools in Marivan County, Iran. The study was conducted between April and July, 2010. Appropriate instruments were used to measure the relevant variables. The statistical analysis of the data included bivariate correlations, t-test, one-way ANOVA and linear regression.

Results: All HPM variables (perceived self-efficacy, perceived benefits and barriers, activity-related affects, interpersonal and situational influences and commitment to a plan of OHBs) were significantly related to OHBs among the respondents (p < 0.01), and a negative association was found between OHBs and perceived barriers (p < 0.01). All HPM variables were statistically significant predictors of OHBs and accounted for 42.2% of the variance.

Conclusion: Promotion of interpersonal influences and the students' perceived self-efficacy and also commitment to a plan of action should be priorities of any program aimed at promoting OHBs among students. School health care providers should suggest strategies to overcome the barriers of performing OHBs, rather than noting the benefits of these behaviors.
