People are living longer, not only in wealthy countries but in developing nations. Western experts have long conceived of aging as a universal predicament--one that supposedly provokes the same welfare concerns in every context. In the twenty-first century, we must embrace a new approach that prioritizes local agendas and values. In this history of how gerontologists, doctors, social scientists, and activists came to define the issue of global aging, Sivaramakrishnan shows that the United Nations, private NGOs, and transnational philanthropic foundations embraced programs that reflected prevailing Western ideas about modernization. The dominant paradigm often assumed that, because large-scale growth of an aging population happened first in the West, developing societies will experience the issues of aging in the same ways and on the same terms as their Western counterparts. Focusing on South Asia and Africa, As the World Ages shows how regional voices have begun to question this one-size-fits-all model and have argued instead for an approach that responds to local needs and concerns.-- Provided by publisher

The relationship between population aging and inflation has received persuasive attention recently from researchers and policymakers. The existing studies focus mainly on developed countries. According to the (United Nations. (2022). Department of Economic and Social Affairs, Population Division. World population prospects 2022: Summary of results. UN DESA/POP/2022/TR/NO. 3) report, the older population in Northern Africa & Western Asia, Central & Southern Asia, Eastern & South-Eastern Asia, and Latin America & Caribbean regions will grow by more than 100 percent between 2022 and 2050. Thus, shifting the discussion from the developed to the developing countries is critical. This paper seeks to fill a significant gap by addressing the experiences of developing countries. We use panel data for 67 countries (22 developed and 45 developing) from 1970 to 2022. The regression analysis uses ordinary least squares and fixed effects (including country-specific and region-specific time trends). The estimates from baseline models may be biased due to cross-sectional dependency, so we consider the Driscoll-Kraay fixed effect estimator. Also, the Wu-Hausman test confirms that our results do not suffer from endogeneity. The paper's contribution is twofold: i. We find a negative relationship between aging and inflation by including developing countries covering 66 percent of the world's population. These findings are robust to the 10-year average, alternative measures of aging, and additional controls; ii. Ours is the first study, especially for developing countries, to empirically test the role of the fertility rate, population growth, and political channels to explain the deflationary pressure of population aging. The study also discusses different policy measures, including raising the retirement age to mitigate the impact of aging.

To investigate the global incidence of prostate cancer with special attention to the changing age structures. Data regarding the cancer incidence and population statistics were retrieved from the International Agency for Research on Cancer in World Health Organization. Eight developing and developed jurisdictions in Asia and the Western countries were selected for global comparison. Time series were constructed based on the cancer incidence rates from 1988 to 2007. The incidence rate of the population aged ≥ 65 was adjusted by the increasing proportion of elderly population, and was defined as the \"aging-adjusted incidence rate\". Cancer incidence and population were then projected to 2030. The aging-adjusted incidence rates of prostate cancer in Asia (Hong Kong, Japan and China) and the developing Western countries (Costa Rica and Croatia) had increased progressively with time. In the developed Western countries (the United States, the United Kingdom and Sweden), we observed initial increases in the aging-adjusted incidence rates of prostate cancer, which then gradually plateaued and even decreased with time. Projections showed that the aging-adjusted incidence rates of prostate cancer in Asia and the developing Western countries were expected to increase in much larger extents than the developed Western countries.

Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013. Estimates were calculated for disease and injury incidence, prevalence, and YLDs using GBD 2010 methods with some important refinements. Results for incidence of acute disorders and prevalence of chronic disorders are new additions to the analysis. Key improvements include expansion to the cause and sequelae list, updated systematic reviews, use of detailed injury codes, improvements to the Bayesian meta-regression method (DisMod-MR), and use of severity splits for various causes. An index of data representativeness, showing data availability, was calculated for each cause and impairment during three periods globally and at the country level for 2013. In total, 35 620 distinct sources of data were used and documented to calculated estimates for 301 diseases and injuries and 2337 sequelae. The comorbidity simulation provides estimates for the number of sequelae, concurrently, by individuals by country, year, age, and sex. Disability weights were updated with the addition of new population-based survey data from four countries. Disease and injury were highly prevalent; only a small fraction of individuals had no sequelae. Comorbidity rose substantially with age and in absolute terms from 1990 to 2013. Incidence of acute sequelae were predominantly infectious diseases and short-term injuries, with over 2 billion cases of upper respiratory infections and diarrhoeal disease episodes in 2013, with the notable exception of tooth pain due to permanent caries with more than 200 million incident cases in 2013. Conversely, leading chronic sequelae were largely attributable to non-communicable diseases, with prevalence estimates for asymptomatic permanent caries and tension-type headache of 2·4 billion and 1·6 billion, respectively. The distribution of the number of sequelae in populations varied widely across regions, with an expected relation between age and disease prevalence. YLDs for both sexes increased from 537·6 million in 1990 to 764·8 million in 2013 due to population growth and ageing, whereas the age-standardised rate decreased little from 114·87 per 1000 people to 110·31 per 1000 people between 1990 and 2013. Leading causes of YLDs included low back pain and major depressive disorder among the top ten causes of YLDs in every country. YLD rates per person, by major cause groups, indicated the main drivers of increases were due to musculoskeletal, mental, and substance use disorders, neurological disorders, and chronic respiratory diseases; however HIV/AIDS was a notable driver of increasing YLDs in sub-Saharan Africa. Also, the proportion of disability-adjusted life years due to YLDs increased globally from 21·1% in 1990 to 31·2% in 2013. Ageing of the world's population is leading to a substantial increase in the numbers of individuals with sequelae of diseases and injuries. Rates of YLDs are declining much more slowly than mortality rates. The non-fatal dimensions of disease and injury will require more and more attention from health systems. The transition to non-fatal outcomes as the dominant source of burden of disease is occurring rapidly outside of sub-Saharan Africa. Our results can guide future health initiatives through examination of epidemiological trends and a better understanding of variation across countries. Bill & Melinda Gates Foundation.

ObjectiveTo systematically review the research conducted on prevalence of frailty and prefrailty among community-dwelling older adults in low-income and middle-income countries (LMICs) and to estimate the pooled prevalence of frailty and prefrailty in community-dwelling older adults in LMICs.DesignSystematic review and meta-analysis. PROSPERO registration number is CRD42016036083.Data sourcesMEDLINE, EMBASE, AMED, Web of Science, CINAHL and WHO Global Health Library were searched from their inception to 12 September 2017.SettingLow-income and middle-income countries.ParticipantsCommunity-dwelling older adults aged ≥60 years.ResultsWe screened 7057 citations and 56 studies were included. Forty-seven and 42 studies were included in the frailty and prefrailty meta-analysis, respectively. The majority of studies were from upper middle-income countries. One study was available from low-income countries. The prevalence of frailty varied from 3.9% (China) to 51.4% (Cuba) and prevalence of prefrailty ranged from 13.4% (Tanzania) to 71.6% (Brazil). The pooled prevalence of frailty was 17.4% (95% CI 14.4% to 20.7%, I2=99.2%) and prefrailty was 49.3% (95% CI 46.4% to 52.2%, I2=97.5%). The wide variation in prevalence rates across studies was largely explained by differences in frailty assessment method and the geographic region. These findings are for the studies with a minimum recruitment age 60, 65 and 70 years.ConclusionThe prevalence of frailty and prefrailty appears higher in community-dwelling older adults in upper middle-income countries compared with high-income countries, which has important implications for healthcare planning. There is limited evidence on frailty prevalence in lower middle-income and low-income countries.PROSPERO registration number CRD42016036083.

Two of every three persons living with dementia reside in low‐ and middle‐income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high‐income countries (HICs), with dementia research predominantly focusing on HICs. This imbalance necessitates LMIC‐focused research to ensure that characterization of dementia accurately reflects the involvement and specificities of diverse populations. Development of effective preventive, diagnostic, and therapeutic approaches for dementia in LMICs requires targeted, personalized, and harmonized efforts. Our article represents timely discussions at the 2022 Symposium on Dementia and Brain Aging in LMICs that identified the foremost opportunities to advance dementia research, differential diagnosis, use of neuropsychometric tools, awareness, and treatment options. We highlight key topics discussed at the meeting and provide future recommendations to foster a more equitable landscape for dementia prevention, diagnosis, care, policy, and management in LMICs. Highlights Two‐thirds of persons with dementia live in LMICs, yet research and costs are skewed toward HICs. LMICs expect dementia prevalence to more than double, accompanied by socioeconomic disparities. The 2022 Symposium on Dementia in LMICs addressed advances in research, diagnosis, prevention, and policy. The Nairobi Declaration urges global action to enhance dementia outcomes in LMICs.

Purpose Poverty alleviation is a global challenge. Human society has never ceased to fight against poverty. China was once the developing country with the largest rural poor population in the world. Remarkable achievements have been made in China’s antipoverty program over the past decades, shaping a unique poverty reduction strategy with Chinese characteristics. The purpose of this paper is to first review the history of China’s rural reform and antipoverty, and then analyze the related policy systems, mechanism innovations and future challenges in poverty alleviation and development. At last, some specific policy implications were provided. Design/methodology/approach Literature on China’s antipoverty history was reviewed and mechanism innovations on targeted poverty alleviation strategy were investigated. Findings Along with the deepening of the rural reform, the poverty alleviation and development in new China have undergone six stages, and experienced a transformation from relief-oriented to development-oriented poverty alleviation. The object of poverty alleviation has gradually targeted with a transformation from poor counties/areas to villages/households, and the effectiveness of poverty alleviation is also gradually improved. However, the increase in the difficulty of antipoverty, fragile ecological environment, rapid population aging and rural decline poses challenges to the construction of a well-off society in an all-round way in China. Specific antipoverty measures were put forward based on the investigation. Finally, the authors emphasize the importance of strengthening the study of poverty geography. Originality/value This study investigates the history of China’s antipoverty policy and analyzes the future challenges for implementing targeted poverty alleviation policy. These findings will lay a foundation for the formulation of China’s antipoverty policies after 2020, and provide experience for poverty alleviation in other developing countries around the world.

The past decade has brought an increasing recognition to the importance of pension systems to the economic stability of nations and the security of their aging populations. During this time, the World Bank has taken a leading role in addressing this challenge through its support for pension reforms around the world. Old-Age Income Support in the 21st Century attempts to explain current policy thinking and update the World Bank’s perspective on pension reform. The Bank has been involved in pension reforms in nearly 60 countries, and the demand for its support continues to grow. This book incorporates lessons learned from recent Bank experiences and research that have significantly increased knowledge and insight regarding how best to proceed in the future. The book has a comprehensive introduction and two main parts. Part I presents the conceptual underpinnings for the Bank’s thinking on pension systems and reforms, including structure of Bank lending in this area. Part II highlights key design and implementation issues where it signals areas of confidence and areas for further research and experience, and includes a section on regional reform experiences, including Latin American and Europe and Central Asia. This book will be of interest to Bank clients, the international community, and anyone interested in pension systems and reform.

Aging is a universal process that can cause diminished function of organs and various diseases. The most striking consequences of aging can be seen visibly on the skin, which acts as a barrier against various external insults. Aging of the skin consists of intrinsic and extrinsic processes that work in concert and influence each other. Intrinsic aging involves biochemical degenerative processes that gradually takes place with age. Extrinsic aging are biochemical processes driven by external influences that lead to aging. There are significant morphological changes at all levels in aged skin that have a profound effect on the characteristics of the skin. Even though skin is subjected to damage by external insults, it is equipped with a healing capability in order to restore its normal structure and function. However, aging has a significant impact on the skin’s healing function by prolonging the inflammatory phase and increasing the production of reactive oxygen species (ROS). This shifts the healing process towards having more protein degradation, which can lead to chronic wound healing with an abundance of complications.
