It has been found that people with disabilities remain at the margin as far as the different aspects of their lives are concerned. This paper tests the hypothesis that disability leads to lower quality of life among older adults in low and middle-income countries. The data from the Study on Global Ageing and Adult Health (SAGE) was used in this study which was conducted in Ghana, China, India, Russia, South Africa and Mexico. The disability scores have been made utilising Item Response Theory, Partial Credit Model and are centered on eight functioning and health areas. Bivariate analysis, binary logistic regression and pooled regression analysis have been used to fulfil the objectives of the paper. The findings reveal that disability acts as a hindrance in attaining a high quality of life (HQOL) amongst the older adults in the above mentioned low and middle-income countries. The older adults with disability are as much as 60% less likely to enjoy an HQOL with respect to the older adults without disability. Better socio-economic development like improved health care for disabled older adults with disability enhanced living standards for both abled and disabled, efficient pension schemes for older adults with disability and effective social service schemes would be very much essential to improve overall QOL among older adults.

Though a continued increase in life expectancy is a significant public health achievement, keeping older adults active and maintaining their well-being is challenging. Active aging requires physical health, mental health, functional independence, economic stability, social participation, and spiritual identification. Among all these factors, social cohesion has significant importance, but there is a dearth of studies focusing on older adults' social cohesion. Thus, the present study focuses on the level of social cohesion among older adults and its variation among the different economic classes. This article uses data from the Study on Global AGEing and Adult Health (SAGE) conducted in China, Ghana, India, Mexico, Russia, and South Africa during 2007–10. Social cohesion scores have been constructed using Item Response Theory Partial Credit Model. Also, bivariate analysis, concentration curves, concentration indices, and multivariate regressions have been used for the analysis presented in this paper. This study confirms the strong predictive power of age, wealth, education, and working status of older adults on their social cohesion across the countries. Higher social non-cohesion is found among the economically poor older adults in Mexico, Russia, India, and China. In contrast, it is just opposite in the case of older adults in South Africa. Governments should develop policies to foster a society with a high level of social inclusion, social capital, and social diversity, to achieve further advancement in social cohesion.

This paper introduces a deterministic fractional-order epidemic model (FOEM) for studying the transmission dynamics of the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). The model highlights the substantial role of unaware and undetected HIV-infected individuals in spreading the disease. Control strategies, such as wielding condoms, level of preventive measures to avoid infection, and self-strictness of susceptibles in sexual contact, have been incorporated into the study. The basic reproduction number ℛ 0 α has been derived, which suggests the conditions for ensuring the persistence and elimination of the disease. Further, to validate the model, actual HIV data taken from Mexico and India separately have been used. The disease dynamics and its control in both countries are analyzed broadly. The values of biological parameters are estimated at which numerical solutions better match the actual data of HIV patients in the case of fractional-order (FO) instead of integer-order (IO). Moreover, in the light of ℛ 0 α , our findings forecast that the disease will abide in the population in Mexico, and at the same time, it will die out from India after a long time.

5. Must We Wait for Youth to Speak Out before We Listen? International Youth Perspectives and Climate Change Education
- Author

Karsgaard, Carrie and Davidson, Debra
- Abstract
In recent years, youth across the planet have begun to mobilise, motivated by the perceived injustices associated with the causes, consequences and politics of climate change. However, education systems lag behind, preoccupied with the "what" and "how" of climate change, rather than engaging it as a social issue in which students themselves are implicated. In this paper, we share the results of our participatory research exploration into youth and climate change through an international education project, in which 99 students from 13 countries joined virtually in a climate change learning experience, culminating in the collaborative development and presentation of a White Paper to the 2018 IPCC Cities and Climate Change Conference. Grounded in a critical global citizenship education framework, this project provides a site to explore climate change education from the perspectives of diverse youth, who inform possibilities for climate change education that addresses justice, individualisation and emotionality.

Background The obstetric transition model suggests that, as countries economically develop, the primary causes of maternal mortality change. Countries are assigned to one of five stages based on their maternal mortality ratio to identify priorities for reducing maternal deaths based on predominant determinants of mortality at each stage. We aim to validate the obstetric transition model using data from six diverse low- and middle-income countries representing self-identified priorities for improving maternal health and measurement compiled in a multi-stakeholder process. Methods We used multiple data sources from Bangladesh, Cote d'Ivoire, India, Mexico, Nigeria, and Pakistan, which included secondary data on country context and primary data derived from two sources: the content of multi-stakeholder meetings, called National Dialogues, which were organised around the 11 key themes identified in the World Health Organization's "Strategies toward ending preventable maternal mortality" (EPMM) and follow-up key informant interviews conducted in five of the seven countries. We conducted the analysis in four phases examining, the country's contextual profile, mapping the key themes and indicators to the model, exploring stakeholder prioritisation, and examining reasons for divergence from the model. Results Our results suggest that the stages of the obstetric transition generally align with the social, epidemiological, and health systems characteristics that the model predicts to be associated with countries at each stage, with some deviation related to health system deficiencies and barriers to access. Stakeholder priorities in maternal health generally align with those predicted by the model. Equity and women's rights emerged as a priority throughout all stages, not only within countries that are more advanced in the transition, as predicted by the model. Deviations between the model's predictions and country-level prioritisation were often explained by context-specific challenges. Conclusions This study is one of the first to validate the obstetric transition model using real data. Our findings support the validity of the obstetric transition model as a useful guide to aid decisionmakers in prioritising attention towards addressing maternal mortality. Country context, including equity, remains important to further inform priority-setting. [ABSTRACT FROM AUTHOR]

Objectives: We aimed to examine the relationship of pain with suicidal ideation and suicide attempts with depressive symptoms among adults aged ≥50 years from six low‐ and middle‐income countries (LMICs) (China, Ghana, India, Mexico, Russia, and South Africa). Methods: Cross‐sectional, community‐based, nationally representative data from the WHO Study on global AGEing and adult health were analyzed. Self‐reported information on past 12‐month suicidal ideation and suicide attempts among people with depressive symptoms was collected. Pain was assessed with the question "Overall in the last 30 days, how much of bodily aches or pain did you have?" With answer options: "none", "mild", "moderate", "severe/extreme". Multivariable logistic regression was done to assess associations. Results: Data on 34,129 adults aged ≥50 years (mean [SD] age 62.4 [16.0] years; males 47.9%) were analyzed. Compared to no pain, mild, moderate, and severe/extreme pain were associated with 2.83 (95% CI = 1.51–5.28), 4.01 (95% CI = 2.38–6.76), and 12.26 (95% CI = 6.44–23.36) times higher odds for suicidal ideation. For suicide attempt, only severe/extreme pain was associated with significantly increased odds (OR = 4.68; 95% CI = 1.67–13.08). Conclusions: In this large sample of older adults from multiple LMICs, pain was strongly associated with suicidal thoughts and suicide attempts with depressive symptoms. Future studies should assess whether addressing pain among older people in LMICs may lead to reduction in suicidal thoughts and behaviors. Key points: Thirty‐four thousand one hundred twenty‐nine adults aged ≥50 years (mean [SD] age 62.4 [16.0] years; males 47.9%).Pain was strongly associated with suicidal thoughts.Pain was strongly associated with suicide attempts.Future studies should assess whether addressing pain may reduce suicide.

- Abstract
Motivating effortful behaviour is a problem employers, governments and nonprofits face globally. However, most studies on motivation are done in Western, educated, industrialized, rich and democratic (WEIRD) cultures. We compared how hard people in six countries worked in response to monetary incentives versus psychological motivators, such as competing with or helping others. The advantage money had over psychological interventions was larger in the United States and the United Kingdom than in China, India, Mexico and South Africa (N = 8,133). In our last study, we randomly assigned cultural frames through language in bilingual Facebook users in India (N = 2,065). Money increased effort over a psychological treatment by 27% in Hindi and 52% in English. These findings contradict the standard economic intuition that people from poorer countries should be more driven by money. Instead, they suggest that the market mentality of exchanging time and effort for material benefits is most prominent in WEIRD cultures., (© 2024. The Author(s).)

Purpose: Food insecurity and multimoribidity (i.e., ≥ 2 chronic conditions) may be linked bidirectionally, but there are no studies on this topic from LMICs. Therefore, the aim of the present study was to examine the association between food insecurity and physical multimorbidity in a large representative sample of older adults from six LMICs. Methods: Cross-sectional, community-based data on adults aged ≥ 50 years from the World Health Organization's Study on Global AGEing and Adult Health (SAGE) conducted in China, Ghana, India, Mexico, Russia, and South Africa were analyzed. A total of 11 chronic physical conditions were assessed. Past 12 month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Multivariable logistic regression analysis was conducted to assess the associations. Results: Data on 34,129 adults aged ≥ 50 years [mean (SD) age 62.4 (16.0) years; age range 50–114 years; 47.9% males] were analyzed. After adjustment for potential confounders, in the overall sample, compared to being food secure, moderate and severe food insecurity were associated with 1.29 (95% CI 1.06–1.56) and 1.56 (95% CI 1.13–2.16) times higher odds for multimorbidity, respectively Conclusion: Food insecurity was associated with greater odds for multimorbidity in older adults from LMICs. Addressing food insecurity in the general population may reduce risk for multimorbidity, while screening for food insecurity and addressing it among those with multimorbidity may lead to better clinical outcomes, pending future longitudinal research [ABSTRACT FROM AUTHOR]

Age group typically identifies millennials – those born between 1982 and 2004. Yet our research challenges the designation based on age group by considering this population in the context of an individual's citizenship or culture. Based on tenets of social identity theory, we explore a citizen's personal value orientation and cognitive moral reasoning to discover commonalities or differences across individuals from eight countries. We report wide variations among citizens' personal value orientations and principled moral reasoning despite being borne within an identified age group. We conclude that an individual's geographic context is a stronger classification descriptor based on values and moral reasoning than their age-based generational categories. Implications for business practice and scholarly research are discussed. [ABSTRACT FROM AUTHOR]

The current study looks at the causes of carbon dioxide (CO
2 ) emissions by considering the implications of remittances in the presence of economic growth, financial development, and energy consumption in the case of selected four G-20 economies over the period 1990–2019. This study first uses the dynamic simulated ARDL model to stimulate, estimate, and plot to predict graphs of negative and positive changes occurring in the variables along with their short-run and long-run relationships. Results of the ARDL bounds test confirm a long-term relationship among remittances, financial development, economic growth energy consumption, and CO2 emissions. Furthermore, the error correction model (ECM) also confirms the long-run relationship among CO2 emissions, remittances, financial development, economic growth, and energy use. The results of a novel dynamic simulated ARDL disclosed that financial development is completely connected to CO2 emissions in Mexico and India in the long run. On the other hand, results confirm that there is a positive relationship between remittances and CO2 emissions in the case of Australia, Germany, and India, but this relationship is insignificant with CO2 emissions in the case of Mexico. The result further disclosed that renewable energy exerts a significant impact on CO2 in Australia, Mexico, India, and Germany in the long run while remittances wield a significant impact on CO2 emissions in Australia, Mexico, and India. Moreover, the findings concluded that GDP has significant nexus with CO2 in the long run in the case of Australia, Mexico, and Germany. This study uses up new visions for the economies of G-20 countries to sustain financial and economic growth by protecting the environment from pollution through its efficient national environmental policy, fiscal policy, and monetary policy.

Background and purpose: Social engagement is an important active aging strategy to promote older adults' mental health. The purposes of this study were to compare social engagement in older populations around the world and explore associations with mental health outcomes. Materials and methods: An international cross‐sectional survey was conducted from 2017 to 2019. Data were retrieved from The International Social Survey Programme for a secondary data analysis across 30 countries. This study applied the Taxonomy of Social Activities and its six levels as operational definitions for a consistent concept of social engagement for international comparisons. Results: In total, 9403 older adults with a mean age of 72.85 ± 6.40 years responded. The highest levels of older adults' social engagement were found in Switzerland, Thailand, and New Zealand. Older adults of a higher age, with a lower educational level, who were permanently sick or disabled, who had no partner, who were widowed or whose civil partner had died, who lived alone, and who had lower self‐placement in society had significantly lower social engagement than did their counterparts. In the regression model, older adults' social engagement positively predicted general health, self‐accomplishment, and life satisfaction, but negatively predicted loneliness and depression. Conclusions: In aging societies worldwide, encouraging older adults' social engagement would be beneficial to promote mental health. Implications for nursing practice and health policies: Community professional nurses can develop strategies of social engagement based on the needs and sociodemographic factors of older adults to improve their mental health. Developing efficient strategies and local policies by learning from successful experiences in other countries is important to promote social engagement in aging societies. [ABSTRACT FROM AUTHOR]

The Centers for Disease Control and Prevention works to eliminate tuberculosis (TB) disease by finding and treating cases of TB disease and expanding latent tuberculosis infection (LTBI) testing and treatment to prevent TB disease. Approximately 70% of reported TB cases in the United States occur among non-U.S.–born persons. We conducted 15 focus groups with U.S. residents born in the six most common countries of birth among non-U.S.–born TB patients: Mexico, the Philippines, India, Vietnam, China and Guatemala. Participants reacted to 39 messages on LTBI and TB disease risk factors, the Bacille Calmette-Guérin (BCG) vaccine, and LTBI testing and treatment. There was low awareness of LTBI, the TB blood test, and how the TB blood test is not affected by prior BCG vaccination. Several participants thought TB disease is contracted by sharing kitchenware. Some felt negatively targeted when presented with information about countries where TB disease is more common than the U.S. Findings highlight the need for communication aimed at increasing LTBI testing and treatment to include messages framed in ways that will be resonant and actionable to populations at risk. Focus groups revealed LTBI misconceptions which highlight areas for targeted education to decrease TB stigma and increase LTBI testing and treatment. [ABSTRACT FROM AUTHOR]

The theoretical connection between decentralization and the representation-cum-efficiency advantage in combating poverty has been questioned by empirical evidence. How decentralization shall be integrated with the intervention from higher-level governments in anti-poverty efforts remains unclear. Drawing on the comparison of India (West Bengal), Mexico, and China, this analysis examines the institutional designs of the poverty alleviation programs across the cases, including the selection of recipients, allocation of fiscal resources, and monitoring, and the political dynamics that generate the designs. Despite differences in the level of poverty and political backgrounds preceding the programs, the key contributors to their success in reducing poverty lie in some common factors, including the strong commitment of the ruling authority to poverty reduction, decentralization in beneficiary identification, and centralized arrangements that reduce elite capture and the power of local brokers. These findings advance our understanding of the endogenous political nature of anti-poverty efforts and the importance of integrating devolution with centralized arrangements in the war against poverty.

- Abstract
Background: Professional development (PD) in a range of occupations has become increasingly digitised. Numerous digital courses are available, with evidence that social media, blogs and apps are increasingly being used for PD. Yet despite clear benefits, there is little robust evidence on the characteristics of digital PD that impact positively on learning and practice, particularly for physical education (PE) teachers and youth sport coaches. This paper provides new insights into the characteristics of effective PD in the context of a complex digital landscape. Purpose: While advocated as an innovative genre from which to optimise learners' proclivity for sharing, curiosity and discovery, little is known about how professional learners respond to massive open online courses (MOOCs) courses to inform their practice. The purpose of this study was to understand how participants responded to the learning design of two MOOCs (n = 13,104 from 155 countries) in the fields of physical education and youth sport coaching. Methods: Drawing from a mixed methodology, data were generated from semi-structured interviews (n = 27) and online survey methods (n = 66) with participants across both MOOCs. Findings: New data offer insights into the features of course design that practitioners found positive in promoting engagement. It was apparent in the data, for example, that four features were influential: establishing relevance, facilitating bridging, designing for personalisation, and building community. Constructed themes reflect how participants organised and negotiated MOOC experiences, and illuminate the ways in which they navigated and used course content. Evidence from this study provides insights into the ways in which digital genre for PD might be structured to facilitate engagement and presents broader challenges to the ways in which pedagogy is conceptualised and practiced online. Conclusions: The refined focus on digital genre as a form of social action in this study seeks to ensure that learners needs can be met in a complex and ever-changing PD digital landscape. In this regard, a more nuanced approach is required that helps explicate the cognitive tools that participants engage as they organise their learning experiences on digital platforms, and how this aligns with their expectations and needs of online PD.

Aim: The association between visual impairment and mild cognitive impairment (MCI) has not been investigated to date. Thus, we assessed this association among older adults from six low- and middle-income countries (LMICs) (China, India, Ghana, Mexico, Russia, and South Africa) using nationally representative datasets. Methods: Cross-sectional, community-based data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. Visual acuity was measured using the tumbling ElogMAR chart, and vision impairment (at distance and near) was defined as visual acuity worse than 6/18 (0.48 logMAR) in the better-seeing eye. The definition of MCI was based on the National Institute on Aging-Alzheimer's Association criteria. Multivariable logistic regression was conducted. Results: Data on 32,715 individuals aged ≥ 50 years [mean (SD) age 62.1 (15.6) years; 51.2% females] were analyzed. Compared to those without far or near vision impairment, those with near vision impairment but not far vision impairment (OR = 1.33; 95% CI = 1.16–1.52), and those with both far and near vision impairment (OR = 1.70; 95% CI = 1.27–2.29) had significantly higher odds for MCI. Only having far vision impairment was not significantly associated with MCI. Conclusions: Visual impairment is associated with increased odds for MCI among older adults in LMICs with the exception of far vision impairment only. Future longitudinal and intervention studies should examine causality and whether improvements in visual acuity, or early intervention, can reduce risk for MCI and ultimately, dementia.
