The researchers used data from a Mediterranean Diet trial and found that participants with higher cardiovascular risk had lower depressive status scores after following the diet.
A study by Florida Atlantic University found that aggressive and disruptive children engage in frequent conflicts with classmates to strengthen their position in the group and enhance their popularity. However, this approach can amplify dangers and is not a healthy avenue to well-being.
A new study reveals that people who are resistant to vaccines often had adverse childhood experiences, including abuse and neglect. These early traumas can lead to a legacy of mistrust, causing individuals to view institutions and authority figures with skepticism.
A recent study found that young people in rural areas carry handguns nearly twice as often as urban youths, with one in three reporting carrying by age 26. The study identified six longitudinal trajectories of handgun carrying, suggesting different cultural contexts and motivations for the behavior.
A new study found that e-cigarette use significantly increases adolescents' risk of cannabis use, especially among those with externalizing mental health problems. However, for those with internalizing mental health issues, the relationship is reversed, and they are less likely to begin using cannabis.
A USC-led study reveals that children with binge eating disorder show abnormalities in gray matter density compared to unaffected peers, indicating a possible link between the disorder and brain development. The findings suggest that treatment may need to address underlying brain abnormalities.
A longitudinal study confirmed that adults' religious styles change over a person's lifetime, with most participants moving to a higher style. Factors such as openness to experience and low agreement with their own religion supported this progression, while regression was also observed in a significant number of cases.
A new study found that siblings of children with disabilities score higher in self-reported cognitive empathy than typically developing peers. This may be due to the specific 'advantage' of cognitive empathy in understanding and supporting their sibling relationship.
A 16-year study of over 2,000 Australian children shows that young people who use drugs but quit before adulthood have similar life success as those who never used drugs. The study highlights the importance of stopping drug use in early adulthood to prevent adult health and wellbeing issues.
Researchers at University of Missouri found a long-term association between adolescent psychological well-being and adult cardiovascular disease risk. People who are more optimistic in their youth can lower their chances for heart disease as adults.
A new study found that the Covid-19 pandemic has had a prolonged detrimental impact on mental health, with women in their twenties and early thirties experiencing the biggest increase in mental health problems. The research also showed that older men were the least impacted by the pandemic.
A study by Washington State University found that social support can mitigate the risk of heart disease and death in older American Indians. Higher rates of depression symptoms, poor quality of life, and social isolation were linked to increased mortality, but instrumental social support reversed this effect.

The researchers discovered that smoking causes changes to DNA methylation at specific sites, leading to increased platelet activity and an increased risk of clotting events.
A new study suggests that a behavioral marker in preterm infants can indicate potential development problems. Researchers used digital eye tracking to test the infants' visual motor coordination and found that those who struggled with this task were more likely to face cognitive and social difficulties later on.
Research involving nearly 250,000 US families found that medically assisted reproduction techniques, including IVF, do not significantly affect birth weight and pregnancy term. Once family circumstances are considered, the differences between MAR-conceived babies and naturally conceived children become insignificant.
