Glynn finds small increases in physical activity reduce immobility, disability risks in older adults

image
TUFTS NOW - Adding 48 minutes of moderate exercise per week is associated with improvements in overall physical functioning and decreases in risks of immobility in older adults who are sedentary, finds a new study assisted by author NANCY GLYNN, epidemiology researcher with the Center for Aging and Population Health. 

Epidemiology study named “Most Effective” in geriatric medicine

image
An epidemiology study led senior author ANNE B. NEWMAN and alumna MINI E. JACOB (EPI ’14) was recently named one of the 10 most effective articles in geriatric medicine in 2016 at the American Geriatrics Society Annual Meeting. "Can a Healthy Lifestyle Compress the Disabled Period in Older Adults?" was published in the Journal of the American Geriatrics Society last year, and found that leading a healthy lifestyle not only extends one’s lifespa... 

Rockette-Wagner finds that sitting for long periods each day linked to increased mortality

image
TRIB LIVE - Even people who exercise the recommended two-and-a-half hours per week likely face an increased risk of death if they sit a lot every day, according to a new study on sitting’s health risks. The science of sedentary behavior is more limited than the science of physical activity, said epidemiology’s BONNIE ROCKETTE-WAGNER. She tells people to find creative ways to get up and move around – whether it’s pausing a TV show to get a little ... 

Harrison on school requirements for child vaccines

image
NBC PHILADELPHIA - State officials want both public and private school students to be up-to-date with all their vaccinations within five days of the beginning of the school year, a drastic reduction from the eight months that pupils used to have to get their shots. Epidemiology’s LEE HARRISON says outbreaks of infectious diseases have demonstrated the need for high immunization rates. 

Van Panhuis offers wisdom on some common myths about vaccines for kids

image
CONSUMER REPORTS - Myth 2: It’s Safer to Space Out Kids’ Vaccines. Truth: No. Epidemiologist WILBERT VAN PANHUIS says that’s unwise. The CDC bases the schedule on disease risks and vaccine effectiveness at specific ages, and the way vaccines may interact with each other. To start mixing this up is complicated and can be dangerous. 

Garland and Fabio want more data to understand neighborhood variations in the deadliness of Pittsburgh shootings

image
PITTSBURGH POST-GAZETTE - Dozens of potential factors cause the deadliness rate of shootings to vary widely across the city geographically and from year-to-year. BCHS’ RICHARD GARLAND and EPI’s ANTHONY FABIO, who study troubled youth and violence, wish more police data was available to find patterns in the factors influencing fatality rates. 

Newman contributes to study on how genes affect body mass

image
NATURE COMMUNICATIONS - ANNE NEWMAN, EPI chair, is co-author of a recent article on the largest, most comprehensive genetic study of lean mass to date. By understanding the genetic contributions to lean mass—an indicator of muscle mass—future treatments may be developed to prevent the loss of lean mass with aging. With age, some people develop a condition called “sarcopenia” where they lose critical amounts of muscle mass, to the point that they ... 

30 percent of women have this down-there infection—and they don’t even know it

image
READERS DIGEST - As many as one in three women will develop bacterial vaginosis (BV) at some point in their lives, but most will have zero clue that have an infection that can wreak havoc on their fertility and increase their risk of developing HIV and other sexually transmitted diseases. “Bacterial vaginosis affects nearly 1-in-3 reproductive-aged women, so there is great need to understand how it can be prevented,” said LISA BODNAR, assist... 

Why belly fat really is the worst kind of weight gain, especially for women

image
NBC TODAY - “Studies have shown that it’s not just being overweight that matters, it’s also where you store the fat,” said co-author SAMAR R. EL KHOUDARY, associate professor of epidemiology. “When the fat is near the heart it can be like a metabolically active organ that can secrete toxic chemicals. And because there is no border between the fat and the heart, it’s much easier for those toxic chemicals to pass into the heart." How much fat accum... 

Gary-Webb elected to chair APHA epidemiology section

image
TIFFANY GARY-WEBB, associate professor in BCHS and epidemiology, has been chosen by her peers as chair-elect for the APHA's epidemiology section. Beginning in November, this 6-year commitment consists of 2 years as chair-elect, 2 years as chair, and 2 years as immediate past-chair. Says Gary-Webb, "I see this as an opportunity for GSPH faculty and students who are interested in applied epidemiology to get more connected with the association." 

El Khoudary finds heart disease risk varies by body type and race in women

image
TRIB LIVE - A woman's body shape is uniquely connected to her heart disease risk, particularly in midlife, and different shapes are associated with risks in black women than in white women, according to a new analysis by epidemiologist SAMAR EL KHOUDARY. The study's results strengthen a   similar finding   from three years ago among black and white men. “Being able to show the same thing here among women kind of highlights the importance of vis...

The Gerontological Society of America recently announced that new rankings show its academic journals lead among the most-cited aging publications. The Journal of Gerontology: Medical Sciences, which is edited by ANNE NEWMAN, chair of Pitt Public Health's Department of Epidemiology, upheld its first-place ranking on the list of 32 publications, with an impact factor of 5.957. 

What impact are our TV binge-watching habits having on our health?

image
TV3 EXPOSE  - Ireland's private-TV news broadcaster cites research by Pitt Public Health's BONNY ROCKETTE-WAGNER on the impacts of TV watching on weight gain and diabetes risk. “Television watching (like other sitting behaviours) has very low energy expenditure, and therefore large amounts of time [spent doing it] could lead to energy imbalance and weight gain.”
