Life expectancy increased overall, but masked massive variation at the county level, with some areas experiencing much larger increases than others.

Gap growing between longest and shortest lifespans in the US

A new study found that the gap between the longest and shortest lifespans in the US has grown significantly since 1980, with some counties experiencing life expectancies as low as 66.8 years. Policies to reduce health inequalities are needed, including promoting healthy behaviors and addressing socioeconomic factors.

UK health spending needs to grow faster than GDP

New research suggests UK health spending must increase at a rate faster than GDP to meet growing demand for healthcare services. The J-value model, developed by Professor Philip Thomas, indicates that developed countries like France and Germany are already prioritizing health care as a fraction of their income.

Are dialysis patients being over-screened for colon cancer?

A new analysis reveals that dialysis patients are being screened at a higher rate than their counterparts without kidney failure, with the healthiest patients being more likely to receive screening. The findings suggest that there is substantial over-screening among patients on dialysis, and physicians should carefully evaluate patient...

Yale-led study: Wild chimpanzees have surprisingly long life spans

A 20-year demographic study of wild chimpanzees in Uganda's Kibale National Park revealed that favorable ecological conditions, including abundant food supplies and low predation risk, drive high life expectancy.

Individual lifespans are becoming more similar

Researchers found a mathematical relationship between life expectancy and the convergence of ages at death, observed in various countries, historical periods, and populations. This rule suggests that fewer people are dying prematurely and living beyond average age of death as life expectancy rises.

For smokers with HIV, smoking may now be more harmful than HIV itself

A new modeling study published in The Journal of Infectious Diseases suggests that smoking may shorten the lifespan of people living with HIV more than the virus itself. Smoking cessation is crucial to improve life expectancy and overall health among this population, with significant health and economic benefits.

Hospital choice could determine survival after a heart attack

A new study published in the New England Journal of Medicine found that patients treated at high-performing hospitals after a heart attack live an average of 9 to 14 months longer than those treated at low-performing hospitals. This improvement is largely due to better survival rates during the first 30 days post-heart attack.

Is aging inevitable? Not necessarily for sea urchins

Researchers found that sea urchins with shorter life expectancies do not experience a decline in regenerative capacity with age, contradicting the prevailing theory on evolution of aging. The study suggests that aging may not be inevitable and could be influenced by other factors.

For American youth, rich-poor gap in life expectancy narrowing: Free

A new study by Janet Currie and colleagues reveals a decline in mortality inequality among poor children up to age 20, with improvements most pronounced in poorer counties.

Raising retirement age would widen benefit disparities for disadvantaged

A report suggests that raising retirement age would widen benefit disparities for those with lower life expectancies, placing greater financial burdens on them. The current retirement age of 65 does not reflect increasing life expectancy, and adjusting it could exacerbate existing inequalities.
