A new study published in JAMA found that osteoporotic fractures can double or triple mortality rates for up to 5-10 years after the fracture. The risk is particularly high for hip fractures in women and men over 75, with a nearly threefold increase in mortality.
Researchers found that siblings with mental illnesses are 63% more likely to experience depressive episodes, while those with low IQs are 18% more likely to live near their sibling but have lower emotional attachment. Environmental and social factors also play a role in poor mental health among these siblings.
A new study found that adolescents are more likely to smoke when their parents begin smoking at a young age and the smoking persists over time. The study used longitudinal data to identify parental smoking behaviors as predictors of adolescent smoking risk.
A longitudinal study of 540 adults found that approximately one third of Canadians with physician-diagnosed asthma do not have asthma when objectively tested. Obesity is linked to increased asthma rates in North America, but overdiagnosis may be more common than previously thought, particularly among obese adults.
Drinking more than moderate amounts of alcohol is associated with reduced total brain volume and larger white matter lesions. This finding suggests that heavy drinking may not have the protective effect on brain health previously thought, contrary to its effects on cardiovascular disease risk.
A study published in Circulation found that American Indians have a higher incidence of stroke compared to white and black Americans, with first strokes being more deadly. Risk factors include high blood pressure, diabetes, and cigarette smoking.

Researchers found victims of child maltreatment more likely to perpetrate youth violence and intimate partner violence. The study analyzed data from over 9,300 respondents and found a strong link between childhood abuse and future perpetration of these violent behaviors.
A Northwestern University study found that participants who forecasted a breakup's impact actually felt less distress than expected. Those most in love were the biggest offenders, exaggerating their emotional pain. The research suggests people tend to be more resilient than they think, and recover from breakups sooner than predicted.
A new study from the University of Texas at Austin found obese girls are half as likely to attend college as non-obese girls. The study attributes this disparity to mental health and behavioral issues such as increased risk of suicide, substance abuse, and negative self-image.
Researchers have identified two separate brain networks affected by Parkinson's disease, one regulating movement and the other cognitive function. The study found that standard treatments alter the motor network but not the cognitive network, highlighting the need for new treatments to target cognition.

A new study from the University of Missouri-Columbia found that men with higher levels of traditional masculinity tend to display greater improvement in their recovery from serious injuries. The study suggests that this strength and resilience may encourage men to seek help and recover more quickly.
A national study found that adolescents who had sex early showed a 20 percent increase in delinquent acts one year later compared to those whose first sexual experience occurred at the average age for their school. In contrast, those teens who waited longer than average to have sex had delinquency rates 50 percent lower.
A study spanning 25 years found that early attachment experiences influence adult emotional expression and relationship dynamics. Secure infants tend to form closer friendships and express emotions more effectively in adulthood.
A major new study finds that family income affects children's cognitive skills and social emotional competence when parents experience material hardship, not just their income level. Researchers used data from 21,255 American kindergartners to identify two ways family income impacts children, including the provision of enriching materi...

The study involved an on-road driving test of participants with mild to moderate Parkinson disease and those of similar age without neurological disorders.
A new study found that long-term abstinence from alcohol can resolve many neurocognitive deficits, including short- and long-term memory, planning, learning, and comprehension. However, spatial processing abilities may be impaired, affecting daily activities like driving.
A nationwide study found that private SAT prep classes and tutoring significantly boost scores, but are unaffordable for many students from lower-income families. The study also showed that higher SAT scores are linked to higher rates of college enrollment, particularly in selective colleges.
A large representative survey found that 3.5% of adolescents in the US had ever exchanged sex for drugs or money, with higher rates among African American youths and those from non-traditional family setups. The study also showed a significant link between exchanging sex and drug use, as well as depression and having been forced into sex.
Research from Cornell University suggests that completing high school is associated with reduced smoking rates, particularly for women whose mothers completed more schooling. However, no significant impact on weight was found, with male high school completers actually being more likely to be overweight.
Researchers have developed a non-invasive method to measure beta cell mass in individuals with diabetes using PET-based quantitation of VMAT2 receptors. This approach allows for the estimation of beta cell mass in rats with type 1 diabetes, providing insights into the pathogenesis of diabetes and potential therapeutic interventions.
A recent USC study found that Chinese teens who perceive themselves as overweight, even if they are normal or underweight, are at a higher risk for depression and school-related stress. Girls in the study reported lower grade point averages when they felt overweight, while boys exhibited more aggressive behavior.
A recent study by Dr. Elizabeth Krall Kaye found that cigarette smokers are 70% more likely to need root canal treatment than nonsmokers. Quitting smoking is linked to a lower risk of needing the procedure.
A new longitudinal study by Cornell University finds that food insecurity affects the academic development of school-age children, particularly in reading and social skills. Children from food-insecure families tend to develop more slowly academically, with girls facing additional challenges.
A review of 225 studies found that chronically happy people are more successful across many life domains due to their positive emotions. Happiness is associated with behaviors that lead to further success in work, relationships, and health.
A 15-year longitudinal study found that individuals diagnosed with minor depression were more likely to develop major depression, particularly among young adults (18-29 years old) and women. The study also revealed that cancer and other chronic illnesses did not increase the risk of developing major depression.
Research found that teens with good relationships with parents tend to have friends who are less likely to fight, more involved in extracurricular activities, and have plans for college. Parents' monitoring and supervision also play a role, although the effects were not as consistent.
A major observational study suggests that a healthy diet rich in folates can significantly reduce the risk of Alzheimer's disease. The study, led by UC Irvine researchers, analyzed the diets of over 500 individuals and found that high folate intake was associated with a 55% lower risk of developing Alzheimer's.
Researchers found that women have more global AD pathology due to neurofibrillary tangles and experience clinical symptoms of AD nearly 20 times more often than men. This suggests that Alzheimer's disease is stronger in women, potentially linked to estrogen deficiency or other protective factors.
