Cigarette smoking is one of the preventable causes of diseases and deaths. The most important preventive measure is technique to resist against peer pressure. Any educational program should design with an emphasis upon theories of behavioral change and based on effective educational program. To investigate the interventions through educational program in prevention of cigarette smoking, this paper has used the Extended Parallel Process Model (EPPM).

This study is a quasi‑experimental study. Two middle schools were randomly selected from male students in Shiraz. Therefore, we randomly selected 120 students for the experimental group and 120 students for the control group. After diagnostic evaluation, educational interventions on the consequences of smoking and preventive skills were applied.

Our results indicated that there was a significant difference between students in the control and experimental groups in the means of perceived susceptibility (P < 0.000, t = 6.84), perceived severity (P < 0.000, t = −11.46), perceived response efficacy (P < 0.000, t = −7.07), perceived self‑efficacy (P < 0.000, t = −11.64), and preventive behavior (P < 0.000, t = −24.36).

EPPM along with educating skills necessary to resist against peer pressure had significant level of efficiency in improving preventive behavior of cigarette smoking among adolescents. However, this study recommends further studies on ways of increasing perceived susceptibility in cigarette smoking among adolescents.

The present study as a systematic review investigated and analyzed interventions based on models and theories of health education and promotion in the field of physical activity in women.

Three electronic databases, including Springer, Biomed Central and Science Direct were searched systematically. Only studies were selected that were quantitative, interventional and in English language as well as those that used at least one of the models and theories of health education and health promotion. Finally, 13 studies were reviewed that met the inclusion criteria and published from 2000 to 2013.

Of 13 studies reviewed, 10 studies measured levels of physical activity before and after the intervention, which nine interventions increased physical activity in the intervention group compared to the control group. Studies were conducted in different settings of health promotion including health care centers, community setting and workplace. The most widely used model was the Transtheoretical Model applied in eight of investigations.

It is suggested to focus more on physical activity and duration of interventions to increase the efficacy of interventions. It is suggested to measure changes of physical activity habits in experimental and control groups in interventions based on the transtheoretical model to prepare a complementary scale to assess the efficacy of interventions. According to the results, no study had focused on changes in institutional policies or general health or providing changes in environment related to physical activity.

Regular physical activity has an important role in reducing cardiovascular risk factors and improving metabolic control in patients with type 2 diabetes. This study aims to investigate the effect of physical activity stage-matched intervention on metabolic control in type 2 diabetes patients.

An 8-week physical activity program conducted with 50 type 2 diabetes females who were physically inactive and in precontemplation, contemplation, and preparation stages of change. Participants were divided into intervention and control groups (each group, n = 25). Data were collected by physical activity stage of change questionnaire and metabolic factors were measured by laboratory tests before initiation program. Subsequently, stage-matched physical activity program was conducted for the interventional group. Control group received routine education from the diabetes center. After 8 weeks, physical activity questionnaire filled out by participants and metabolic factors were evaluated by a laboratory test.

Findings showed patients in the intervention group and compared with control group significantly moved through stages of change after physical activity program (P-value < 0.05). Evaluation of physical activity after educational program demonstrated that the intervention group adopted regular physical activity more than the control group and also the difference between groups was significant (P-value < 0.05). Our findings indicate a significant relationship between physical activity level and moving in stages of change in the intervention group (P-value < 0.05). Comparison of metabolism factors after physical activity program showed significant decrease in glycosilated hemoglobin in the intervention group than the control group (P-value < 0.05). However, significant differences between groups were not observed in other metabolism factors.

Designing and implementing physical activity stage-matched intervention can improve metabolic control and management of type 2 diabetes.
