Employing diverse research teams can improve trust and engagement among potential study participants, according to researchers.
A recent study published in The Journals of Gerontology – Series B found that having more children can produce economic, social, emotional, and biological burdens that impact health, especially chronic conditions and depression. In contrast, adults with fewer children were more likely to report poor self-rated health in certain countries.
A new Japanese ecological study found that prefecture-specific SHC participation rates significantly negatively affect treated ESKD incidence and CKD prevalence. Higher SHC participation rates are associated with lower ESKD incidence, suggesting the importance of regular health checkups at a population level.
A new study found that residents of neighborhoods with more greenspace tend to have longer telomeres, indicating better cellular health. However, the positive impact of greenspace is not enough to compensate for other environmental challenges like air pollution and racial segregation.

A new study finds that four out of five Miami-Dade County residents may face disruption or displacement due to sea-level rise, with lower-income people bearing the brunt. As habitable areas shrink and housing prices rise, only a small number of affluent residents can relocate, while many others are trapped in low-lying properties.
A new study reveals a reversal in the trend of early-onset lung cancer, now affecting younger women and middle-aged adults. The increased incidence in women is attributed to rising rates among those born in the 1960s, without higher smoking prevalence.
