Changes in Cause of Death among the Older Adults and Its Effect on Increasing Life Expectancy in Iran
N Zanjari, M Sasanipour,
Volume 18, Issue 1 (5-2022)
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.

Applying the Successful Aging Model in Tehran City

Volume 19, Issue 1 (6-2023)
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.

Abstract
Background and Objectives: Considering the documented impact of attitudes towards aging on quality of life, this study aimed to explore hope in life and its association with attitudes towards aging across various age groups in Qom, Iran.
Methods: This cross-sectional study, conducted in 2021-2022, included 83 children (8-15 years old) and 340 adults (16 years old and above) selected from different age groups based on the Statistical Center of Iran's classification. The systematic random sampling method was used, considering the frequency percentage of each group from the 2015 census. Data were collected through a demographic form, Kogan's Attitudes Toward Older People Scale (KAOPS), and Snyder's Hope questionnaire. Statistical analysis was performed using SPSS-24, incorporating Pearson's correlation coefficient, independent sample t-tests, ANOVA, and linear regression.
Results: The mean and standard deviation of hope in life and attitude towards aging were 25.97±5.81 (ranging from 6 to 36) and 137.38±21.65 (ranging from 34 to 238) in the children's group, and 27.54±4.92 (ranging from 8 to 32) and 154.66±17.30 (ranging from 34 to 238) in the adults' group, respectively. Pearson's correlation coefficient revealed a significant relationship between hope in life and attitude towards aging only in the age groups of 16-24 years (r=0.220, P<0.05) and 25-44 years (r=0.273, P<0.01), while this relationship was not significant in other groups (P>0.05).
Conclusion: Although the relationship between attitude towards aging and hope in life was not strong or significant across all age groups, given the average levels of hope in life across all age groups, promoting positivity and elucidating the positive attributes of aging and the importance of elderly individuals in society can enhance individuals' outlook towards their future life.
