“…Fourth, the effects of population aging on China’s transport CO 2 emissions exhibit regional differences. Our results show that population aging increases transport CO 2 emissions in the central and western regions promotes transportation CO 2 emissions, which is consistent with the conclusion of Guo et al ( 2022 ). However, in the eastern region, aging has no significant effect on transport CO 2 emissions, which is contrary to other scholars (Zhang and Tan 2016 ).…”

Reducing transportation CO 2 emissions and addressing population characteristic changes are two major challenges facing China, involving various requirements for sustainable economic development. Due to the interdependence of population characteristics and transportation, human activities have become a significant cause of the increase in greenhouse gas levels. Previous studies mainly focused on evaluating the relationship between one-dimensional or multi-dimensional demographic factors and CO 2 emissions, while few studies have reported on the effect of multi-dimensional demographic factors on CO 2 emissions in transportation. Analyzing the relationship between transportation CO 2 emissions is the foundation and key to understanding and reducing overall CO 2 emissions. Therefore, this paper used the STIRPAT model and panel data from 2000 to 2019 to investigate the effect of population characteristics on CO 2 emissions of China’s transportation sector, and further analyzed the effect mechanism and emission effect of population aging on transportation CO 2 emissions. The results show that (1) population aging and population quality restrained CO 2 emissions from transportation, but the negative effects of population aging were indirectly caused by economic growth and transportation demand. And with the aggravation of population aging, the influence on transport CO 2 emissions changed and presented a U-shape. (2) Population living standard on transportation CO 2 emissions exhibited an urban–rural difference, and urban living standard was predominant in transportation CO 2 emissions. Additionally, population growth is under a weakly positive effect on transportation CO 2 emissions. (3) At the regional level, the effect of population aging on transportation CO 2 emissions showed regional differences. In the eastern region, the CO 2 emission coefficient of transportation was 0.0378, but not significant. In central and western regions, the influence coefficient of transportation was 0.6539 and 0.2760, respectively. These findings indicated that policy makers should make relevant recommendations from the perspective of coordinating population policy and energy conservation and emission reduction policy in transportation.

“…China's age structure has been changing rapidly due to increasing life expectancy, the baby boomers of the 1940s–1950s, and the “one-child policy” implemented in 1979–2016 to limit excessive population growth, with older people. In particularly, growing faster than any other age group ( Guo et al, 2023 ; Tu et al, 2021 ). By 2030, China may become the most aged country ( Li et al, 2009 ).…”

“…According to estimates, the number of older adults in Iran is projected to exceed 10 million by 2035, with the percentage of elderly individuals surpassing 11% (2). The increasing number of older adults in societies highlights the importance of considering their health requirements (3). Mental health is a significant concern for older adults, and statistics indicate that over 20% of individuals aged 60 and above experience mental or nervous disorders.…”

Background: Mental health help-seeking is the initial step in evaluating one's mental state, receiving an accurate diagnosis and professional intervention for mental health problems. Objectives: The current study aimed to determine the mental health help-seeking attitudes of older adults in Kermanshah. Methods: This descriptive cross-sectional research study was conducted in 2022 among 538 individuals aged 60 and above who were beneficiaries of the pension funds in Kermanshah, Iran. The samples were selected by multi-stage cluster sampling. Data were collected through interviews with older adults using a standardized questionnaire. The collected data were analyzed using SPSS software version 16. Results: The mean age of respondents was 66.01 ± 4.09, ranging from 60 to 75 years. About 39% (210 people) of older adults had positive mental health help-seeking attitudes, and 61% (328 people) had negative mental health help-seeking attitudes. The positive mental health help-seeking attitudes were higher in older adults with higher educational levels (P < 0.001) and better economic status (P = 0.029). Conclusions: The majority of the older adults had a negative attitude towards mental health help-seeking, highlighting the importance of interventions to improve elderly attitudes toward mental health help-seeking.
