Airport Noise May Increase Heart Disease and Stroke Risk
People who live near busy international airports may be at increased risk of heart disease and stroke due to the high levels of noise, according to two new studies in the British Medical Journal. One study looked at hospital admissions around London Heathrow airport, finding the risks were 10 to 20 percent higher when compared to areas with the least noise. The other study, by researchers at the Harvard School of Public Health and Boston University School of Public Health, analyzed data on more than 60 million Americans ages 65 and older living near 89 airports, finding that areas with 10 decibel higher aircraft noise also saw a 3.5 percent increase in the hospital admission rate. Researchers say the link needs further study to show causation. "The exact role that noise exposure may play in ill health is not well established," said Anna Hansell of Imperial College London, who led the British study. "However, it is plausible that it might be contributing, for example by raising blood pressure or by disturbing people's sleep." The findings indicate that populated areas must be looked at closely when communities consider expanding large airports. Read more on heart health.
Private Talk Sessions with NICU Nurses Ease Anxiety in Mothers of Premature Babies
“Listening matters” when it comes to easing the worries of the mothers of premature infants. One-on-one talks sessions between NICU nurses and the mothers can help reduce feelings of anxiety, confusion and doubt, according to a new study in the Journal of Perinatology. "Having a prematurely born baby is like a nightmare for the mother," said Lisa Segre, an assistant professor in the University of Iowa College of Nursing. "You're expecting to have a healthy baby, and suddenly you're left wondering whether he or she is going to live." The study looked at 23 mothers who when through an average of five 45-minute sessions, find they gave mothers a chance to really talk about their worries and were effective at easing concerns across the board. "Listening is what nurses have done their whole career," said NICU nurse and study co-author Rebecca Siewert. "We've always been the ones to listen and try to problem solve. So, I just think it was a wonderful offshoot of what nursing can do. We just need the time to do it." Read more on maternal and infant health.
Early Puberty Tied to Great Risk of Experimentation with Cigarettes, Alcohol and Marijuana
Early puberty is linked to increased risk of experimentation with cigarettes, alcohol and marijuana, according to a new study in the journal Addiction. Puberty typically begins between the ages of 9 and 10, will girls on average beginning it earlier than boys. "While puberty is often thought of as a solely biological process, our research has shown that pubertal development is a combination of biological, psychological and social processes that all likely interact to influence risk-taking behavior like substance use," said study author Jessica Duncan Cance, a public health researcher at the University of Texas at Austin. "Our study suggests that being the first girl in the class to need a bra, for example, prompts or exacerbates existing psychological and social aspects that can, in turn, lead to substance use and other risky behaviors early in life.” Read more on pediatrics.
