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: Self-efficacy and decisional balance in the Trans-theoretical Model play an effective role in oral self-care behavior. The objective of this study was to determine the impact of education on inter-dental cleaning behavior based on the Trans-theoretical Model in pre-universstudents in the city of Yazd, Iran in 2009.

Materials and Methods: This was an intervention study. Based on statistical calculations, 361 pre-university students (mean age 17.53±0.55 years) were randomly allocated into groups of intervention (n=185, 51.2%) and control (176, 48.8%). Data on demographic characteristics, self-efficacy, and decisional balancing (perceived benefits and perceived barriers) were collected using a questionnaire with confirmed validity and reliability. Based on the trans-theoretical model, a 3-month educational program was prepared with sections on self-efficacy and decisional balance and conducted. At the termination of the program variables of the model were evaluated and the gingival index was determined by a dentist. The data were analyzed using the SPSS software, the statistical tests being ANOVA, paired t-test, t-test, Fisher, and correlation coefficient.

Results: Implementation of the educational program resulted in a significant decrease in perceived barriers (p<0.001) and significant increases in perceived benefits (p<0.001) and self-efficacy (p<0.001). In addition, the gingival index improved in the intervention group (p=0.01). The final mean self-efficacy, perceived barriers, and gingival index were not significantly different between the case and control groups, but a significantly positive effect was noticed in perceived benefits (p=0. 01).

Conclusion: The findings indicate that the educational intervention influenced desirably the gingival index, self-efficacy and perceived benefits in the students. Since the self-efficacy factor is an important predictor in oral self-care behavior, it is suggested to use the trans-theoretical model in educational interventions aiming at improving self-efficacy, increasing perceived advantages, and reducing perceived obstacles.

  Background and Aim: High fruit and vegetable intake has been introduced as one of the key factors of healthy diet to prevent chronic disease. This study attempts to explore the fruit and vegetable intake in Arak city and its relationship with demography and socio-economic factors.

  Materials and Methods : In this cross sectional study, 660 people in 18 -70 age range were selected with a two-stage cluster sampling and were interviewed for demography and socio – economic questionnaires and a 56- items semi-quantitative food frequency questionnaire to assess fruit and vegetable intake. After univariate analysis, the association of the significant variables with fruit and vegetable intake was also evaluated with multiple linear regression.

  Results: In this study, over 60 percent of subjects consumed less than the minimum recommended amount of fruit and vegetable (5 servings or 400 gr a day).The total consumption of fruit and vegetable indicated an inverse significant relationship with age (p =0.04 and β = - 0.02), and a direct significant relationship with economic status (p <0.001and β =0.10). The father's educational level (p =0.005 and β =0.38 for diploma level and p =0.03 and β =0.36 for academic education) and physical activity level (p =0.001 and β =0.03 per hour) were factors associated with fruit consumption. The gender was only associated with vegetable consumption so that women had higher consumption in this study (p =0.03 and β=0.23).

  Conclusion: The findings of this study indicate low fruit and vegetable consumption in the population under study. In this study, age, physical activity, and socioeconomic status and fathers’ education were the factors that were significantly associated with fruit and vegetable consumption.

Background and Aim: Cancer is the third cause of mortality in Iran, killing more than 30000 persons annually. The Motivation Theory is a useful approach for predicting and planning intervention programs to change behaviors related to cancer prevention and early detection. Considering the absence of a valid and reliable protection motivation theory questionnaire for cancer early detection in Iran, this study was conducted to design such a questionnaire and assess its psychometric properties in Yazd

Materials and Methods: This was a cross-sectional study. A questionnaire was designed based on similar questionnaires currently in use and its validity and reliability were determined. The reliability coefficients were calculated by Cronbach α and intraclass correlation coefficients. To determine the validity of the scale, two methods were used, namely, face validity and content validity. Confirmation factor analysis was used to determine factorial validity using Amous 21 software .

Results: The CVR for all items of the questionnaire, CVI, ICC and internal consistency of the questionnaire were found to be 1, 0.97-1.0, 0.71-0.98, and 0.65-0.93, respectively. The confirmation factor analysis revealed that the questionnaire fitted the Iranian population. The Cronbach alpha coefficient for the questionnaire constructs varied between 0.71-0.98 and 0.65-0.93

Conclusion: The validity and reliability of the Persian version of PMT scale for cancer early detection are acceptable and suitable, so it can be used in similar research.

Background and Aim: Food poisoning occurs under circumstances where proper action for protecting foods from microbial contamination and chemical toxins is not taken. In the Iranian society women have an important role in preparing food in the home. The objective of this study was to assess the knowledge, attitude and practice (KAP) of women living in Yazd, Iran regarding food poisoning.

Materials and Methods: This was a cross-sectional descriptive study. Data were collected through interviewing 266 women living in Yazd, selected randomly by calling at their homes. Data analysis was performed using SPSS version 18. The minimum and maximum accessible scores for knowledge, attitude and practice were 0 and 15, 15 and 45 and 0 and 20, respectively.

Results: The mean (± SD) score of knowledge, attitude and practice was 11.13 ± 2.54, 39.98 ± 4.52 and 17.73 ± 1.96, respectively. Further analysis of the data showed that 63.2% of the women had no knowledge about safety of refrigerated cooked foods and 41.4% had an erroneous attitude about fruit and vegetable cleaning, believing that merely cleaning them would make them safe to eat. As regards practice, 68.8 % of the women prepared and ate semi-cooked eggs.

Conclusion: Yazdi women lack a sound knowledge about (a). some agents of food poisoning such as, for example, Salmonella and (2). food cooking and preserving temperatures. It is recommended to plan and execute educational programs aiming at promoting knowledge and improving practice of women in these areas.
