Health and population

Health and population dynamics are intertwined, embodying an intricate relationship with significant implications on the Sustainable Development Goals (SDGs). Health is fundamentally at the center of these 17 global goals, aimed to transform the world by 2030. Specifically, Goal 3 endeavors to "Ensure healthy lives and promote well-being for all at all ages." It acknowledges that health is pivotal to human life quality, social cohesion, and sustainable development. Inextricably linked to this are the complexities of population dynamics, including growth rates, age structure, fertility and mortality rates, and migration patterns.

With the world's population projected to exceed 9.7 billion by 2050, the pressure on health systems will undoubtedly escalate. The demographic transition, with an aging population and an increasing prevalence of non-communicable diseases, poses new challenges for health systems globally. Additionally, areas with high fertility rates often overlap with extreme poverty, resulting in heightened health risks, including higher maternal and child mortality rates, malnutrition, and infectious diseases.

Moreover, rapid urbanization and migration present both opportunities and threats to health. While urban areas may provide better access to healthcare, they also harbor risks of disease transmission, air and water pollution, and social determinants of health like inadequate housing and social inequality. Simultaneously, migrants often face disproportionate health risks due to unstable living conditions, exploitation, and limited access to healthcare services.

Achieving the SDGs will necessitate comprehensive approaches that consider the intricate interplay of health and population dynamics. It means strengthening health systems, promoting universal health coverage, and addressing social determinants of health. It also implies crafting policies that recognize demographic realities and foster an environment conducive to sustainable development. Only by understanding and harnessing these dynamics can the world meaningfully progress towards realizing the SDGs, ensuring healthy lives and well-being for all.

Each year, World Hepatitis Day is observed on 28 July to raise awareness of viral hepatitis, which causes inflammation of the liver that leads to severe disease and liver cancer. Elsevier is proud to present a freely available special collection of journal articles and book chapters highlighting hepatitis research.
A Viewpoint in support of SDGs 3, 13, and 17, proposing a range of strategies for developing a 'public health playbook', to counter the 'corporate playbook' used by powerful commercial actors to protect their business interests at the expense of population health and wellbeing, including numerous health-harming and planet-harming industries, such as tobacco, alcohol, gambling, pharmaceuticals, ultraprocessed foods and beverages, firearms and weapons, automobiles, social media and technology, oil and gas, and chemicals.
A Personal View in support of SDGs 3 and 13, summarising the current evidence on climate change and mental health, and outlining opportunities for methodological improvement and innovation in this research field.
A Comment on dementia and Alzheimer's disease costs, in the context of SDG 3, focusing specifically on the costs of care in Europe. Dementia is a syndrome characterized by progressive cognitive and functional impairment, most commonly caused by Alzheimer's disease and other neurodegenerative and cerebrovascular disorders. Costs of care increase dramatically with progressing disease severity, and increasing dementia prevalence due to ageing populations is raising concerns about the sustainability of future costs of dementia care. A new study shows that social welfare systems in Europe cover most of the direct costs of dementia, however they do not protect families and households against the burden of informal care. Meier and colleagues1 set out to calculate the economic costs of dementia in 11 European countries, by combining microdata from a population-based survey with estimates of dementia prevalence. Data for Austria, Belgium, Czechia, Denmark, Estonia, France, Germany, Italy, Slovenia, Spain, and Sweden was obtained from six waves of the Survey of Health, Ageing, and Retirement in Europe (SHARE). The survey captured out-of-pocket expenditures for health and social care as well as unpaid informal care. Costs attributable to dementia were estimated using linear regression, controlling for comorbidities and demographic factors. Finally, costs were combined with prevalence estimates to calculate the annual cost of dementia by country.
This study shows that TB progression risk is higher in native Peruvians, and the conclusions support including more diverse populations in genomic studies to provide better targeted healthcare in indigenous populations.
