The effect of educational intervention based on the theory of planned behavior on improving physical and nutrition status of obese and overweight women.

BACKGROUND: Regarding the high rate of obesity and overweight among women, develop a comprehensive and effective program it seems necessary to improve their nutritional behaviors and physical activity. This study aims to survey the effect of educational intervention based on the theory of planned behavior (TPB) on improving physical and nutritional activities of obese and overweight women. METHODS: This experimental study was performed on 400 obese and overweight women over the age of 20. The sampling method was A simple random sampling. The data collection was valid and reliable self-reports measure, questionnaires. This tools was including demographic information, questionnaire based on the constructs of the theory of planned behavior, physical activity performance questionnaire and nutritional performance questionnaire that individuals completed before and 6 months after the educational intervention. The training intervention for the experimental group consisted of 12 sessions of 50-55 min. Data analyzed by SPSS22 and by using chi-square test, independent t-test and paired t-test. RESULTS: Findings showed that before the educational intervention, was no significant difference between the experimental and control groups in terms of education, household monthly income, occupation, mean age, marital status, awareness, attitude, perceived behavioral control, subjective norms, physical activity and nutritional behavioral intentions, and physical activity and nutritional performance, weight and BMI. However, six months after the training intervention, there was a significant increase in each of the TPB contracts, weight and BMI in the experimental group, while no significant difference was observed in the control group. The meaningful level was considered 0.05. CONCLUSION: Our findings partially support of applying theory of planned behavior in reducing the weight, BMI and improved nutritional performance and physical activity of the study subjects. TPB could be an important strategy for effective future educational interventions.

Effect of educational program based on theory of planned behavior on promoting nutritional behaviors preventing Anemia in a sample of Iranian pregnant women.

BACKGROUND: Iron deficiency anemia (IDA) is one of the most common problems during pregnancy. The aim of this research was to determine the effect of educational program based on Theory of Planned Behavior (TPB) on promoting nutritional behaviors preventing anemia in a pregnant woman in Shiraz city, Iran. METHODS: This quasi-experimental study was done on 150 pregnant women (75 experimental and 75 control groups) who were selected using randomly sampling method in in Shiraz city, Iran, in 2020-2021. The educational intervention for the experimental group included six educational sessions for 50 or 55 min-based TPB model. A questionnaire consisted of items about demographic information, TPB constructs (attitude, perceived behavioral control, subjective norms and behavioral intention) was used to measure the nutritional behaviours preventing iron deficiency anemia in pregnancy women before and 3 months after the intervention. RESULTS: The results showed that before the educational intervention, there was no significant difference between the two groups in terms of knowledge, attitude, perceived behavioral control, subjective norms, behavioral intention and nutritional performance; however, three months after the educational intervention, the experimental group showed a significant increase in each of the mentioned variables. For example the mean and standard deviation score of behavioral intention after intervention in the experimental group was significantly increased (25.57 ± 1.66, P = 0.001),and the mean and standard deviation score of performance after intervention in the experimental group was significantly increased (31.03 ± 2.19, P = 0.001), (P < 0.05). CONCLUSIONS: After the educational intervention, the experimental group showed a significant increase in of the knowledge, attitude, perceived behavioral control, subjective norms, behavioral intention and nutritional performance. Therefore the results of the study showed positive effect of nutrition educational intervention program base on TPB model on improvement of iron deficiency anemia preventive behaviours in the pregnancy women.

Components Affecting the Promotion of COVID-19 Disease Prevention Behaviors among Iranian Students: A Qualitative Study by Using the PRECEDE Model.

Background: COVID-19 is a social health problem. Several risk factors threaten students, and schools can provide a suitable environment for managing and performing health promotion programs. Given the extensive spread of the disease and the existence of multilevel components affecting the adoption of preventive behaviors, understanding the views and opinions of the audience about the barriers and facilitators affecting the behavior using qualitative studies can be one of the ways to have a successful intervention. Materials and Methods: This was a qualitative study performed by a directed content analysis method while using the PRECEDE model (predisposing, reinforcing, enabling constructs in educational diagnosis and evaluation). In total, 38 individuals (teachers, parents, and students) were entered into the study using the purposive sampling method. Data were collected by semistructured interviews, and the implemented data were systematically classified into five stages (condensed meaning units, code, subcategory, category, and theme) and were arranged and analyzed. Results: The findings are classified into three themes of predisposing, enabling, and reinforcing factors. In addition, perceived sensitivity, perceived intensity, mental beliefs, behavior outcome evaluation, and perceived power were considered as subcategories of predisposing factors, whereas normative beliefs and motivation for adherence to protocols were subcategories of reinforcing factors, and control beliefs were subcategories of enabling factors. Conclusion: Our findings could be used as a guide to design educational interventions aiming at promoting COVID-19 prevention behaviors in schools.

Using Social Marketing to Reduce Salt Intake in Iran.

Objectives: WHO has recommended that the average salt intake must be <5 grams per day. However, people consume salt much more in many countries. In this study, we design and implement an intervention based on social marketing model to reduce salt consumption in Yasuj, Iran. Materials and Methods: This study employed a quasi-experimental pretest-posttest with control group design which consisted of a formative research (qualitative-quantitative) and an interventional phase. To collect the qualitative data, six focus group discussions by participating of 66 people were established. The qualitative data were analyzed manually using directed content analysis. In quantitative study, 166 people aged 25-50 years completed a KAP questionnaire, and their average salt intake was determined through measuring sodium in their urine sample. By analyzing the data, marketing mix components were determined for designing an intervention. An educational package (including posters for installing in the kitchen, pamphlets, phone counseling, four educational classes, and brief interventions done by physicians and other health personnel) focused on reducing salt intake and using alternatives was developed. For one month, program was implemented for intervention group. Two months later, KAP survey and measuring the urine sodium were repeated for intervention and control groups. The data was compared for two groups, before and after the intervention by using independent t-test, paired t-tests and repeated measures ANOVA. Results: The qualitative findings showed that most participants agreed that the salt intake was high in Iran. Most of them recommended home-based and family-driven strategies to reduce salt intake, offered using healthier alternatives for salt, and recognized physicians and health care providers in healthcare facilities as the most important to encourage people to reduce salt intake. After the intervention, the mean and standard deviation of KAP were improved significantly in intervention group. The mean salt intake decreased significantly by 3.01 ± 2.38 in the intervention group and repeated measures ANOVA showed significant change over time (P < 0.001) and a significant difference between two groups (P = 0.04). Also, the interaction between time and group was significant (P = 0.001). Conclusion: The mean salt intake among the study population was approximately three times more than the level recommended by the WHO. The social marketing-based intervention succeeded in reducing the salt intake of the study subjects by ~3 grams on average.
