This finding highlights the long-term impacts of incarceration on health, particularly among marginalized communities.
A new index ranks US states based on their support for successful aging across five domains: productivity, security, equity, cohesion, and well-being. The study found that no single domain drives the results, and state policies play a significant role in adapting to an aging population.
Historical state-level analysis finds that increased party competition leads to higher spending on infrastructure, human capital, literacy, earnings, and longevity. States with more party competition tend to have lower infant mortality, higher life expectancy, and greater social well-being.
A study published in The BMJ found that more than 28 million extra years of life were lost worldwide in 2020 compared to expected numbers, with a higher rate of excess premature deaths in men than women. This analysis provides insight into the full impact of the COVID-19 pandemic on populations.

Those with possible sarcopenia exhibited higher degrees of frailty despite normal Specific Health Checkup results, highlighting the need for a test to identify sarcopenia early on.
A study found that higher omega-3 acid levels in the blood are associated with a significant increase in life expectancy, similar to quitting smoking. The researchers analyzed data from over 2,200 people aged 65 and found that four types of fatty acids, including omega-3, can predict mortality risk.
A new study found that decreases in local government funding over recent years probably contributed to declines in life expectancy in some areas of England. The research linked annual local government funding data with life expectancy and mortality data between 2013 and 2017, revealing a significant impact on the most deprived areas.
A new study published in Age and Ageing found that hypothetical adverse life scenarios, such as dementia and chronic pain, significantly reduce people's desire to live into older ages. The study analyzed data from Norway, where the average preferred life expectancy was 91.4 years.

Life expectancy in the US decreased by nearly two years between 2018 and 2020, widening the gap with other high-income countries, especially among Hispanic and Black Americans. The largest declines were observed in these groups, with life expectancy falling by 15-18 times more than in peer countries.
A recent study found that life expectancy and lifespan equality in humans and non-human primates are not driven by aging rate, but by early life mortality rates. The researchers analyzed data from nine human populations and 30 non-human primate groups, revealing a strong relationship between early-life deaths and population aging.
Researchers found that human life expectancy increase is not due to slowing aging but rather improved survival rates among children and young adults, supporting the 'invariant rate of ageing' hypothesis which suggests a relatively fixed rate of ageing across species.
A new study led by Fernando Colchero reveals a strong link between human life expectancy and lifespan equality. Researchers analyzed data from nine human populations and 30 non-human primate populations, including gorillas, chimpanzees, and baboons, to explore the invariant rate of ageing hypothesis.
