Abstract
Background and objectives: Considering the high contribution of unintentional accidents to mortality, particularly in males in Iran, and their changes over the last decade, a study was conducted to review the share of deaths due to unintentional accidents in sex difference in life expectancy at birth in the country over the last decades.
Methods: The mortality data for the years 2006 to 2015 were obtained from the Ministry of Health and Medical Education. Then, the child mortality was corrected using the intercensal generational method and adult mortality was corrected for underreporting based on the Bennett-Horiuchi method. The contribution of mortality changes due to unintentional accidents to increase in females’ life expectancy was calculated using the ARIAGA decomposition method.
Results: The sex differential in life expectancy was about 3.5 years in 2006 in Iran, which decreased to 2.9 years in 2011 and increased to 3 years in in 2015. The unintentional accidents in all three periods played a dominant role in sex differential mortality, but its contribution over time was significantly reduced, with a contribution of 60% to around 42% between 2006 and 2015.
Conclusion: Due to the slowdown in the increase in life expectancy at birth in Iran in recent decades, attention to differential mortality, including sex difference in mortality and identification of potentials to increase life expectancy according to different groups, can increase life expectancy.

Abstract
Background and Objectives: The rate of the increase in life expectancy has slowed down during the last two or three decades in Iran. In this study, we examined the role of change in thecause of death older adults in increasing life expectancy in Iran between 2006 and 2016.
Methods: Death data by age, sex, and cause in Iran between 2006 and 2016 were obtained from the death registration and classification system of the Ministry of Health and Medical Education. Using the Brass-Trussell and generalized Benett-Horiuchi method, underreporting of child and adult death registration was corrected. Then, using the Arriaga decomposition method, the role of age groups and causes of death of Iranian older adults in increasing life expectancy at birth was calculated.
Results: Men’s life expectancy at birth increased by 3.7 years during 2006 to 2016, and the contribution of older adult’s death changes on this increase was estimated at 2 years. Out of the total increase of 3.1 years in women’s life expectancy, 1.57 years was related to changes in the older adults’ cause of death. Furthermore, 74% and 57% of the role of change in the cause of death among older men and women in increasing the life expectancy was related to cardiovascular diseases.
Conclusion: Considering the transition of age structure in the coming decades, transition of death trend to older ages is expected to continue. The results of this study showed that it is necessary to pay more attention to diseases that affect older people in policy priorities.

Abstract
Background and Objectives: This research aims to investigate the components of Rowe and Kahn's successful aging model, encompassing the absence of disease and disability, high cognitive and physical performance, and active participation in life among the elderly population in Tehran in 2020, considering both genders.
Methods: This study utilized a survey approach, involving a sample of 637 individuals aged 60 years and above in Tehran. The sample was selected using a multi-stage cluster sampling method from 22 districts of Tehran, considering the elderly population in each district. Confirmatory structural equation modeling (SEM) was employed to assess whether Rowe and Kahn's model aligns with the collected data.
Results: The study's findings demonstrated that Rowe and Kahn's model exhibited a strong statistical fit (p<0.01). Factor loadings in the overall population model and among the two genders were statistically significant and varied. Across the three dimensions of successful aging (avoiding disease and disability, maintaining physical and cognitive functioning, and continuing engagement with life), avoiding disease and disability was the most strongly associated with successful aging, regardless of gender. However, in the other two dimensions, the significance and strength of participation in life and physical and cognitive function varied based on gender.
Conclusion: Programs to support the physical health of the elderly, especially in chronic diseases resulting from lifestyle choice should be developed, and increasing active participation should be a priority, which requires interventions in youth and middle age.
