Background and Objective:One of the most important challenges in public health is to improve the quality of life in elders. Aging may cause various disorders such as disabilities, high risk conditions and some chronic disease. In this study the effect of educational intervention based on precede–proceed on quality of life in elders was examined.Materials & Methods:This semi experimental study was carried out on 128 elders over 60 years in Zahedan that were randomly selected by multi-stage sampling method and divided in to control and intervention groups. Data collection tool was a triploid questionnaire that included demographic data, questions of precede-proceed constructs and SF-36 questionnaire. The validity and reliability of questionnaire confirmed by experts and Cranach’s Alpha coefficient (76%). After primary data collecting, educational intervention was performed and after nine months data was collected again and analyzed in spss.16 soft-ware using descriptive and analytical statistics.Results:The results showed that mean score of quality of life in participants was low and more than 61% of them had a mean score less than 50%. After intervention the mean score of quality of life only in experimental group significantly increased from 47.72 to 58.90. Behavior and self-rated health were the strongest predictors for quality of life in this study.Conclusion:Implementation educational intervention based on precedes-proceed model can improve quality of life in elders. Elderly women and older elderly individuals compared with elderly men and younger elderly should be considering as an important risk factor for reducing HRQOL.

Background and Objective: Several studies indicate low knowledge and poor performance of girls in puberty and menstruation. Puberty complications are easily preventable. Consequently, present study mainly aims to determine the effect of educational interventions based on Health Belief Model (HBM) on puberty health behaviors in Tehran's female elementary students, 2019. Material and Method: This study was quasi-experimental using random sampling methods for selecting among female elementary students in Tehran, District 14, 2019. Data collection was performed through a designed questionnaire based on HBM. The questionnaire's reliability and validity were verified. Students filled out the questionnaire prior to the intervention. Educational interventions were performed for intervention group in three 45-minute sessions. Two groups filled out questionnaires a month after intervention. The data was analyzed through SPSS v.24 using k-square, Independent t, paired t, Anova variance and Ancova covariance. Results: Findings showed demographic variables were not significantly different in two groups (p > 0.05) except in their father's occupation, menstruation beginning's awareness and age. In the case group after intervention, mean knowledge, average of perceived susceptibility, average of perceived severity, average of self-efficacy, average of perceived benefits and average behavior increased and average of perceived barriers decreased. They were significantly different in the intervention group (p<0.05), except in perceived benefits and self-efficacy, but not in the control group (p>0.05). The results of Ancova covariance test showed that educational intervention based on HBM had a significant effect on students' health during puberty (P <0.05). Conclusion: The educational intervention based on HBM could change the puberty health awareness and behavior.

Background and Objective: The health literacy, skills and abilities of individuals are in line with appropriate decision making in the field of health promotion. Adolescents are the age groups whose basic health literacy is essential for their nutritional practice. The aim of this study was to determine the relationship between health literacy and nutritional practice in adolescents. Methods: The present study is a descriptive cross-sectional study that was performed on 400 boy and girl youngsters were selected by multistage-random sampling during the academic year 2015. The data were collected through questionnaires that included three parts: a) individual characteristics b) health literacy (HELMA) c) the nutritional practice. Data analysis was performed with SPSS version 20 and proportional tests. Results: 50% of female participants, with an average age of 17 years and 74.5% of adolescents had Limited (inadequate and not so adequate) health literacy, 68 percent had average nutritional practice. There was a direct correlation between aspects of health literacy with nutritional practice. Namely, by increasing health literacy, nutritional practice is improved. (P-value< 0/001). Conclusion: The results of this study showed the role of health literacy in the nutritional practice of the adolescents. Due to high levels of limited health literacy in adolescents, health education interventions are necessary to improve health literacy among teenagers.
