The findings suggest that workplace conditions play a crucial role in employee health.
A recent study by the Life Course Socio-Economic Status (LCSES) study found that male combat veterans are more likely to be heavy drinkers and smokers compared to non-veterans and non-combat veteran controls. The researchers also discovered that older men with distant combat exposure had higher odds of obesity and physical inactivity.
A recent study found that advertisers who switched from a majority to a minority language (typically English to Spanish) elicited more negative thoughts and lower product evaluations than those switching in reverse. This suggests that consumers perceive minority languages as having less prestige, affecting persuasion.
A recent study found that stroke warning signs, such as transient ischemic attacks (TIAs), often occur several hours or days before the actual stroke. In most cases, TIAs occurred within seven days of the stroke, highlighting the importance of timely assessment and preventive treatment.

The study also recommends that TV stations keep their lengthier breaks away from the beginning and end of shows. By doing so, advertisers can prevent channel surfing and optimize their ad placements.
A recent study screened over 13,000 female new recruits at the Army's induction center and found a high prevalence of chlamydia infections, particularly among young women.
Female Mediterranean fruit flies exhibit two distinct aging patterns when food supply is limited, delaying reproduction until advanced age. Once a complete diet is available, they produce eggs rapidly and age swiftly, suggesting reproduction as a key factor in aging.
Mediterranean fruit flies exhibit two distinct modes of aging based on food supply, with limited protein leading to delayed reproduction and high protein enabling rapid production and aging. This study reveals surprising findings about the relationship between nutrition, reproduction, and longevity in these insects.
Researchers found that depression is associated with erectile dysfunction (ED) in men, with moderate to complete ED occurring almost twice as often in those with depressive symptoms. The study used data from the Massachusetts Male Aging Study and found a significant link between ED and depressive symptomatology.
Research on aging presents a surprising finding: mortality rates decrease with age in various species.

A Duke University study found that working mothers' stress hormone levels increase even with just one child at home, putting them at a higher risk for health problems. The study also showed that the number of children does not affect stress levels, and that quality of work and family experiences may be key factors in stress levels.
A new study found that 41% of current AFDC recipients will reach the 60-month cutoff for lifetime receipt of welfare, and 52% will be forced to seek employment or work activity. States have options to exempt up to 20% of caseloads, but millions of families will still be affected.
A 30-year follow-up study found that men who ate about 35 grams of fish per day had a significantly lower risk of dying from a heart attack than those who did not eat fish. The findings held true after accounting for various demographic and health factors, supporting the view that eating fish protects against heart attacks.
