As of 2023, it is estimated that Type 2 diabetes (T2D) affects approximately 783 million people worldwide, with South Asians presenting the highest age-adjusted comparative diabetes prevalence among adults (90,204.5 people). Ethnicity has been highlighted as a major risk factor for the development of T2D with central adiposity, insulin resistance, and unfavorable lipid profile identified as predominant signals of alarm. Leading databases, including Web of Science, Medline, PubMed, Google Scholar, and ScienceDirect, were consulted, and manual searches were carried out for cited references in leading diabetes-related journals. Genetic predisposition, central adiposity, and unfavorable lifestyles, including physical inactivity and an unhealthy diet, have been found to be associated with the prevalence of T2D in migrant South Asians. Additionally, “Westernization,” acculturation, socioeconomic factors, and lack of awareness regarding seriousness and consequences of the disease have also been identified as contributors to the development of T2D in this population. However, the higher prevalence of T2D in migrant South Asians may not be entirely attributed to genetic predisposition; hence, ethnicity and associated modifiable risk factors warrant further investigation. Preventive measures and appropriate interventions are limited by the lack of ethnic-specific cut-off points for anthropometric and biological markers, as well as by the absence of reliable methods for dietary and physical activity assessment.

Disparities in Healthcare Access and Outcomes Among Racial and Ethnic Minoritized People with Intellectual and Developmental Disabilities
Sandy Magaña, Nazanin Heydarian, and Sandra Vanegas
Compared to the general population, people with intellectual and developmental disabilities (IDD) face worse health outcomes, and outcomes are even worse for children and adults with IDD from minoritized populations. Examining the intersection of people with IDD from minoritized groups is critical to understanding appropriate policies and services that promote health among all people with IDD. People with IDD from minoritized racial and ethnic groups have greater exposure to detrimental social determinants of health, which leads to poor access to adequate healthcare and poor health outcomes. Policies that aim to improve health outcomes among people with IDD and that are related to their disability and appropriate accommodations are not enough. Policies need to address poverty in families, racism and discrimination, poor housing, and other social determinants that are more prevalent among minoritized populations. Most research on racial and ethnic disparities among children and adults with IDD has been conducted in the United States. While there is emerging research globally on racial and ethnic disparities, there a paucity of this research in the field of IDD. Furthermore, there may be detrimental health effects for other minoritized groups, such as religious minorities, but research is lacking in this area. Clearly, more research on these intersections is needed in the global context.
Drowning: Global Burden, Risk Factors, and Prevention Strategies
Aminur Rahman, Amy E. Peden, Lamisa Ashraf, Daniel Ryan, Al-Amin Bhuiyan, and Stephen Beerman
Drowning has been described as a major global public health problem and has recently been acknowledged by a United Nations Declaration on Global Drowning Prevention. While drowning impacts countries of all income levels, the burden is overwhelmingly borne by low- and middle-income countries (LMICs) who account for 90% of the global death toll. In addition, there is scarce data collection on drowning in LMICs, so the magnitude of drowning may be far greater than is represented. A range of factors including sex, age, education, income, access to water, a lack of swimming skills, certain occupations like commercial fishing, geographically isolated and flood-prone locations, preexisting medical conditions, and unsafe water transport systems, influence the risk of drowning. Some behavioral factors, such as alcohol or drug consumption, not wearing life jackets, and engaging in risky behaviors such as swimming or boating alone, increase drowning risk. Geopolitical factors such as migration and armed conflict can also impact drowning risk. There is a growing body of evidence on drowning prevention strategies. These include pre-event interventions such as pool fencing, enhancing community education and awareness, providing swimming lessons, use of lifejackets, close supervision of children by adults, and boating regulations. Interventions to reduce harm from drowning include appropriate training for recognition of a drowning event, rescue, and resuscitation. An active and/or passive surveillance system for drowning, focusing on individual settings and targeting populations at risk, is required. Drowning requires coordinated multisectoral action to provide effective prevention, rescue, and treatment. Therefore, all countries should aim to develop a national water safety plan, as recommended in the WHO Global Report on Drowning. Further research is required on the epidemiology and treatment of drowning in LMICs as well as non-fatal and intentional drowning in both high-income countries (HICs) and LMICs. Effective and context-specific implementation of drowning prevention strategies, including pilot testing, scale up and evaluation, are likely to help reduce the burden of both fatal and non-fatal drowning in all countries.
Environmental Health in Latin American Countries
Luiz Augusto Cassanha Galvao, Volney Câmara, and Daniel Buss
The relationship between environment and health is part of the history of medicine and has always been important to any study of human health and to public-health interventions. In Latin America many health improvements are related to environmental interventions, such as the provision of better water and sanitation services. Latin America’s development, industrialization, and sweeping urbanization have brought many improvements to the well-being of its populations; they have also inaugurated new societies, with new patterns of consumption. The region’s basic environmental-health interventions have needed to be updated and upgraded to include disciplines such as toxicology, environmental epidemiology, environmental engineering, and many others. Multidisciplinary and inter-sector approaches are paramount to understanding new profiles of health and well-being, and to promoting effective public-health interventions. The new social, economic, labor, and consumption aspects of modern Latin American society have become more and more relevant to understanding the complex interactions in the region’s social, biological, and physical environment, which are essential to explaining some of the emerging and re-emerging public-health problems. Environmental health, as concept and as intervention, is simple and easily understood, but no longer sufficient to achieve the levels of health and well-being expected and required by these new realities. Many global changes such as climate change, biodiversity loss, and mass migrations has been identified as main cause of ill health and are at the center of the sustainable development challenges in general, and many are critical and specific public health. To face this development, other frameworks have emerged, such as planetary health and environmental and social determinants of health. Public health remains central to some, such as the improved environmental-health agenda, while others assign public health a relative position in a variety of overarching frameworks.
Implementation and Dissemination of Evidence-based Programs for the Prevention and Management of Chronic Conditions in Older Adults: Theoretical Perspectives and Case Examples from the United States
Marcia G. Ory, Chinelo K. Nsobundu, and Yeka W. Nmadu
More than 50 million Americans are currently 65 and older, with current projections estimating that there will be nearly 100 million by 2060. While there is great variability among the older population, many older adults will be disproportionately affected by negative health and well-being consequences associated with chronic diseases, increased fall risk, and physical inactivity. The implementation and dissemination of evidence-based programs can play a major role in the prevention and management of these conditions, thus improving quality of life for the growing number of older adults worldwide. These goals are consistent with the World Health Organization Declaration of the Decade of Healthy Ageing. Research and practice around evidence-based programs for chronic illness management and related conditions in older adults have spearheaded many new opportunities to promote healthy aging as well as revealing challenges in getting effective programs and policies implemented and widely disseminated. For example, most evidence-based programs are not readily scalable or sustainable. Reasons for this may include delay in implementing programs as a result of contextual barriers or the lack of infrastructure for dissemination. These challenges emphasize the need for strategies to ensure the successful implementation and dissemination of evidence-based programs for older adults. Dissemination and implementation science (DIS) provides a broad framework to design interventions and identify implementation strategies that work in diverse real-world clinical and community settings to meet the need of diverse populations. Advancements in research and practice require a basic understanding of (a) principles of DIS; (b) relevant theories, frameworks, and conceptual models; (c) awareness of national and international case examples of chronic disease, falls, and physical activity initiatives for better management of health and functioning in older adults; and (d) shared lessons from research and practice. This lens helps underscore the importance of the evidence-based program movement to the aging services network.
Migrant Health in Refugee Camps: A Neglected Public Health Issue
There are 1 billion migrants in the world today, which means that one in seven of the world’s population are migrants. Of these, 272 million are international migrants and 763 million are internal migrants. It is estimated that around 70 million of the world’s migrants, both internal and international, have been forcibly displaced. Many things force people to leave their homes in search of a better future: war, poverty, persecution, climate change, desertification, urbanization, globalization, inequality, and lack of job prospects. Migrants remain among the most vulnerable members of society even when their living conditions improve after migration. Migrant women and children are a particularly vulnerable group and have a great need for basic and preventive health care. Many refugees and migrants are young and in good health, but hard living conditions and difficulty accessing basic health care can affect their state of health. Many of them face inhuman journeys during migration and live in refugee camps with very low standards of hygiene; when they find a job, they are often exploited. All these things can also affect their mental health. Migrants struggle with similar challenges as other marginalized groups when it comes to access to health care, but they face the additional barriers of mobility, language barriers, cultural differences, lack of familiarity with local health care services, and limited eligibility for publicly and privately funded health care. Governments should provide affordable preventive and basic health care to refugees and migrants not only because it is a human right but also because in the long term it can lower the costs of the whole health care system.
Prevention of Suicide
Around 700,000 people take their lives each year worldwide. Suicide accounts for approximately 1.3% of all deaths and therefore represents a major public health problem. The global age-standardized suicide rate is 9 per 100,000 population, yet there are large variations among genders, ages, countries, and world regions. The stress–vulnerability model of suicidal behaviors has been proposed to explain how a diathesis, developed through the influence of genetic and neurodevelopmental factors in relation to perinatal, postnatal, and life experiences, interacts with different risk and protective factors that either decrease or enhance the individual’s level of resilience to stress and suicidal risk. Public health suicide prevention strategies include suicide means restriction, reducing harmful substance use, promoting responsible media reporting, public-awareness campaigns, gatekeeper trainings, school-based interventions, crisis helplines, and postvention. Mental health strategies comprise identification, treatment, and rehabilitation of persons in distress and at risk for suicide. Multicomponent strategies that use a combination of evidence-based methods from public and mental health sectors are recommended. Future work should aim at enhancing the quality of epidemiological data, improving the research on protective and ideation-to-action factors, expanding the quantity and quality of data coming from low- and middle-income countries, and evaluating the cost-effectiveness of different suicide prevention strategies.
Psychosocial Aspects of Cardiovascular Disease in African Americans
Amy L. Ai, Hoa B. Appel, and Sabrina L. Dickey
Cardiovascular disease (CVD) is the leading cause of death in the United States, but the burden of CVD falls disproportionately on racial and ethnic minority populations. Blacks are especially impacted by CVD. Since the 2010s, mortality from CVD has declined and life expectancy disparity between White and Black males has decreased. However, the mortality rate in Blacks remains the highest among all racial and ethnic groups. For example, concerning survival differences between White and Black patients with acute myocardial infarction, 5-year mortality for Black patients is significantly higher than that for White patients. Also, hypertension or high blood pressure and stroke, two of the most disabling diseases, burden Blacks much more than other groups. Furthermore, several major CVD comorbidities or risk factors are linked with disparity in Blacks, especially diabetes, obesity, and chronic kidney diseases. Physical inactivity is a major risk factor. Blacks and Hispanics, as well as Asian American women, all have higher rates of physical inactivity compared with Whites. The literature indicates the remarkable psychosocial and environmental issues that underlie CVD disparities in Black populations. Specifically, the social determinants of health (SDOH) have been shown to be significant indicators of CVD morbidity and mortality causing a disproportionate impact on racial and ethnic minorities and low socioeconomic status populations. These SDOH involving economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context provide a framework for a multifactorial approach to understand the impact of CVD on the Black community. The Black community has a history of trauma from racism and discrimination, which is still evident in the existence of structural racism. Trust in the health care system within the Black community remains an ongoing issue and stems from the unethical Tuskegee Study. The lack of trust in the U.S. health care system by the Black community is evident in the limited number of Black participants in research and the excess of health disparities within the Black community. Utilizing SDOH provides a context for understanding the complexity of addressing health disparities among historically marginalized groups. A unifactorial approach will not suffice when there are a number of physical, psychosocial, economic, and environment factors that adversely impact the health of underserved and underrepresented groups such as African Americans. Stringent policies to address racism, discrimination, and adequate access to health care for the Black community must be implemented to decrease the presence of CVD as a health disparity. Without the presence of a social and physical environment that provides adequate resources, such as health care services, quality education to attain employment and be health literate, employment to afford access to health care, and the support to engage in preventive care, African Americans will continue to suffer from various health disparities, such as CVD, and have shorter life spans compared to other racial and ethnic groups.
Rebooting Education: A Keystone to Ending Racial and Ethnic Minority Health Disparities
William A. Vega and Esther J. Calzada
Undermining educational attainment at any stage is a threat to life course health. A strong educational platform is required for adequate human development in the 21st century because it provides a foundation for lifelong knowledge, skills, and competencies that protect health. The importance of educational attainment for health has been acknowledged but remains understudied as an interdisciplinary issue. In US American society, unequal educational opportunity is a historical reality and is reflected in health disparities among African American and Latinx populations over the life span. Reform efforts have been initiated for decades, yet gains in educational attainment show limited progress and wide disparities in lifetime health persist. Educational attainment is a fundamental social determinant of health because it leverages higher income, improves the management of other social determinants of health, improves social skills, improves occupational life chances, and extends life expectancy. The reverse is also true. Low educational attainment that is intergenerational imperils human development by failing to prepare youth with the capabilities to overcome structural disadvantages and poverty, which themselves imperil development. African American and Latinx populations in the United States, who together represent nearly 100 million people and who will be the largest component of the majority-minority American population by the year 2046, confront a web of aversive social determinants, including poverty in de facto segregated communities, violence and trauma, toxic exposures, poorly compensated and often temporary employment, a lack of universal health insurance, racism, and sexism in their daily lives. Clearly, there are social, biologic, and psychological issues associated with the educational attainment and health gradient, and early childhood learning experiences represent a critically important opportunity for human potential by advancing cognitive performance, problem-solving ability, motivation to learn, and overall structural and functional brain development. Families from low educational attainment backgrounds experience the negative impacts of social determinants in their daily lives, and their children’s life chances are diminished by poorly funded schools with ineffective educational programs. Putative causes and potential responses to overcoming the historical problem of neglect have been identified, and there are promising efforts at educational system reform aiming to promote health with effective programs and comprehensive strategies that will close the gaps in educational attainment.
The Role of Service User Preferences and User-Centered Approaches in Adult Social Care
Helen Dickinson and Robin Miller
In recent years we have seen growing interest in a range of countries around how service user preferences can be accommodated in adult social care and how these services might be oriented to be more user-centered. There is a diverse array of different initiatives that might be classified as creating more user-centered approaches. Those at the strategic (macro) and organizational (meso) levels typically have greater amounts of evidence available than those at the individual (micro) level. However, many of these struggle to significantly disrupt power relations and clearly demonstrate an impact on service users. Those at the micro level more readily demonstrate impact, although the very local nature of these interventions means that they are not always well evaluated, and lessons may not be easy to transfer from one context to another. Overall, there is no system that has managed to reorient its adult social care system in a wholesale way; this is an issue that requires both technical and cultural change. Such changes take time to achieve, but there is much that can be learned from the existing evidence base.
Time in Health Promotion and Public Health
Being physically active and eating fresh foods could reduce the growing burdens of cardiovascular disease, cognitive decline, obesity, some cancers, diabetes type II, depression, and anxiety. Increasing these health behaviors has been a public health focus for decades, yet over one half of adults around the world remain insufficiently physically active and four in ten are overweight or obese. When people are asked why they don’t exercise more or eat healthy food, the most common reason they give is lack of time. Everyone has 24 hours in a day, so why do so many people say they lack time to be healthy? Time is a challenging (and intriguing) concept. Usually, time is thought about in terms of hours and minutes which evenly divide a day, and its lack a consequence of misguided priorities. This assumes that all hours are equal and available for use and that every person has agency over their time. Although having sufficient time is fundamental to health (exercising, preparing healthy food, resting, accessing services, and maintaining social bonds all take time), other dimensions such as control, flexibility, intensity, and timing are essential for understanding how time and health are connected. Like income, time is exchanged and given within households, so it can be fruitful to view time as a household resource rather than an individual’s resource. In the labor market, time is exchanged for payment, and this underscores time’s potency as a social and economic resource. Historically, research on the social determinants of health and health equity have focused on the harms linked to work hours, including the length and timing of the work day and flexible hours. Yet this research missed the importance of time outside the labor market, which alters the health consequence of work hours, delivering only a partial analysis of how time shapes health. Research since the early 2000s is supplying new evidence of the interplay between work, care, and other non-market time, allowing a more accurate insight into how time shapes health and how this relationship connects to social and gender equity. Debates remain, however, and these include the extent to which time pressure and time scarcity are problems of motivation and perception and whether time scarcity is a problem of only the affluent. There are precedents to address time costs and inequities. A first step for health prevention and health promotion practitioners is to value time in ways comparable to how the field values money. This would mean limiting the time costs of health interventions and services, including the requirement to “find time” outside of work or care roles to be healthy. The field also needs to challenge the idea that the income-poor are time-rich since this is rarely the case if they are caregivers. As well as minimizing time burdens, policies to address the social determinants of time from urban planning, transport systems, and work-hour regulations will be critical to achieving a fairer and healthier world.
