A study published in the International Journal of Manpower found that offering paid time off (PTO) significantly reduces the likelihood of employees quitting their jobs, with a greater reduction for men. PTO does not affect job satisfaction, which independently reduces turnover by 30-40%. Flexible scheduling also reduces turnover, but ...
A new study provides the first nationwide picture of who knows about, carries, and uses naloxone to reverse deadly opioid overdoses. The survey found that people's perception of overdose risk correlates with their decision to carry naloxone, and those with high-risk profiles are more likely to carry the drug.
A study by UCL researchers found that the number of adults vaping in England who have never regularly smoked increased sharply since 2021, with most vaping daily. The study estimated that about one million adults who had never regularly smoked now vape in England, a sevenfold increase since 2021.

A nationally representative sample of community-dwelling adults found that stroke prevalence remained stable overall, but increased among men. The study's estimates underestimate the total burden due to institutional settings not included in National Health and Nutrition Examination Surveys.
A new study published in the American Journal of Preventive Medicine found that reducing added sugars consumption by an average of 14 to 57 calories per day is sufficient to meet the Healthy People 2030 target. This represents just less than half of a 12-ounce soft drink, and requires minimal changes to dietary habits.
A recent survey experiment by Regina Bateson reveals that people with pandemic employment gaps are perceived more negatively than those who remained employed. This stigma could have long-term social and economic consequences for individuals who lost their jobs during the pandemic.

The most common adverse childhood experiences include emotional abuse, parental separation, and household substance abuse.
A study published in the American Journal of Preventive Medicine found that nearly 1 in 3 US veterans who own firearms store at least one loaded gun unlocked. This practice contributes to heightened suicide risk among vulnerable individuals who perceive firearms as a means of protection.

A recent UTMB study found that oxygen therapy is being prescribed more frequently among COPD patients, especially women over 75 with multiple health conditions. The study's results show an increase in oxygen use from 2001 to 2010, likely due to improved survival rates and decreased stigma around the treatment.

Lap belts are also more effective than riding unrestrained, with a statistically significant reduction in injuries.
New research from the University of Toronto finds that workers with higher job authority report significantly higher levels of interpersonal conflict. Younger workers with power face the highest level of conflict in the workplace, while men with authority report more conflict than similarly-positioned women.
Researchers analyzed data from a US national survey and found that lower sodium diets were associated with a significantly increased risk of cardiovascular disease. The study casts doubt on long-held assumptions about the risks of high-salt diets.

Researchers found that the cognitive ability gap between blacks and whites has decreased significantly since 1972, with blacks making notable gains in cognitive tests. The study's findings suggest a possible correlation between social equality progress and IQ gains, potentially indicating further improvements.
A study published in The Lancet found that New Zealand's Maori patients had a higher risk of preventable adverse events in hospital than non-Maori patients. Despite a publicly funded hospital system, Maori received marginally poorer care, with 14% of admissions associated with adverse events compared to 11% for non-Maori populations.
A study published in the Journal of the American Dietetic Association found that preschoolers who consumed more fiber had more nutrient-rich diets. Experts suggest increasing fiber consumption through whole-grain products and high-fiber cereals to support healthy growth and development.
A new study published in Psychosomatic Medicine found that workers with little control in their jobs were 43-50% more likely to die during a five-to-ten year period. The research team suggests that 'alienating' work could lead to social disengagement and high-risk behaviors, increasing mortality risk.
