IRP Study Gets Kids Moving to Improve Blood Sugar Control

Interrupting Sedentary Time Could Help Stave Off Health Problems

Tuesday, April 18, 2023

Many people don’t get much exercise these days, and kids are no exception. Whether at school, doing homework, or entertaining themselves online, children and teens spend hours on end sitting around. That lack of physical activity raises their risk for metabolic conditions like obesity and type 2 diabetes, but according to a recent IRP study, breaking up those long, sedentary periods with just a few minutes of exercise could yield noticeable benefits for their health.

Moms’ Caffeine Consumption May Affect Babies’ Brains

Findings Could Explain Why Caffeine Exposure In-Utero Increases Kids’ Risk for Obesity

Tuesday, February 21, 2023

Between books, the media, and well-meaning friends and relatives, new parents are inundated with advice about how to set their kids up for a happy and healthy future. However, what parents do before their children are even born can also have a huge impact on how they turn out. For instance, new IRP research suggests that a pregnant woman’s caffeine consumption can rewire her baby’s brain in ways that put the child at increased risk for obesity later in life.

Boosting Brain Activity to Suppress Snacking

Non-Invasive Stimulation Method May Improve Self-Regulation Around Food

Tuesday, November 22, 2022

Marketers make a living from the fact that merely seeing an advertisement for junk food can spur a sudden craving for potato chips or sugary cereal. Some people have an easier time than others resisting such urges, and over-consuming that sort of food can have problematic consequences for health. Findings from a recent IRP study suggest that stimulating a particular part of the brain might help people who struggle with obesity by enhancing their ability to control their desire to snack.

IRP’s Shannon Zenk Elected to the National Academy of Medicine

Nursing Research Leader Sheds Light on How Neighborhoods Influence Health

Monday, April 4, 2022

Dr. Shannon Zenk

When you think about public health, city planning might not be the first thing that comes to mind. Yet where we live — the quality of the buildings, the availability of places to walk and play safely, and the types of schools and stores in the neighborhood — can profoundly affect our health. This relationship has been emphasized by the COVID-19 pandemic, as close, stuffy living conditions, the need to take public transportation to essential jobs, and inequities in access to testing and vaccination sites all contributed to the larger reduction in life expectancy for Black and Latino Americans compared to Caucasians over the last two years.

Shannon N. Zenk, Ph.D., M.P.H., R.N., F.A.A.N., Director of the National Institute of Nursing Research (NINR), was elected to the National Academy of Medicine in 2021 for her research into how neighborhood characteristics affect the health of residents and contribute to the health disparities seen between communities with different racial and ethnic makeups and different levels of income.

Mouse Study Suggests Treatment Strategy Could Benefit Patients with Obesity

Tuesday, March 8, 2022

It’s bad enough that the excess abdominal fat carried by most individuals with obesity causes widespread inflammation throughout their bodies. To add insult to injury, that inflammation actually makes it harder to use up overloaded fat stores. However, a new IRP mouse study supports a two-pronged pharmaceutical approach that could break this vicious cycle and help improve the health of people with obesity.

New Lasker Scholars Begin Breaking New Ground

Early-Career Scientists Power Through Pandemic to Launch Labs

Monday, January 24, 2022

NIH’s 2021 Lasker Clinical Research Scholars

NIH has long prided itself on its ability to accelerate the careers of the brightest young physicians and scientists in the country. One of these many efforts is the Lasker Clinical Research Scholars Program, which provides a select group of individuals relatively early in their scientific careers with the funding and institutional support to start their own labs at NIH. After five to seven years of independent research in the IRP, Lasker Scholars are given the option to apply for three years of funding for work outside of NIH or to remain as investigators at NIH.

While launching a lab in the midst of a global pandemic is no easy task, five Lasker Scholars have done just that over the past year. Their research on cancer, Parkinson’s disease, childhood blindness, and inflammatory conditions is now well underway and promises to eventually improve the lives of many patients. Keep reading to learn more about how NIH’s newest Lasker Scholars are changing the way we treat those illnesses.

Duo Delves Into Genetics of Diabetes

Drs. Leslie Baier and Robert Hanson Identify Genetic Risk Factors in American Indians

Monday, November 29, 2021

A team of researchers at NIH’s campus in Phoenix, Arizona, is working with the local American Indian community to learn about genetic risk factors for type 2 diabetes.

November is both Diabetes Awareness Month and Native American Heritage Month. Unfortunately, the month of November is not the only link between Indigenous populations and diabetes. Members of minority groups have a much higher risk of developing type 2 diabetes and its many complications compared to the general population, and this is especially true of some American Indian tribes, whose members are twice as likely to have type 2 diabetes as white Americans.

At the Phoenix Epidemiology and Clinical Research Branch in Arizona, part of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), IRP senior investigators Leslie J. Baier, Ph.D., and Robert Hanson, M.D., M.P.H., are working to understand why American Indians living in the southwestern U.S. are disproportionately affected by type 2 diabetes and obesity. Using family histories, medical records, and other data collected during a decades-long study of these communities, combined with extensive analysis of some of their participants’ DNA, their team has identified several genes that contribute to risk for those two conditions, along with some surprising findings about their prevalence.

Treatment Approach Could Combat Obesity and Its Consequences

Tuesday, July 20, 2021

When your phone or laptop is low on power, you simply connect it to a charger and find the nearest electrical outlet, but the process of restoring lagging energy production in our cells is not nearly as simple. However, a new IRP study has identified a promising approach for doing just that, which could lead to new treatments for obesity and related metabolic ailments like heart disease and diabetes.

IRP’s Charles Rotimi Elected to American Academy of Arts and Sciences

Pioneering Genetic Epidemiologist Takes a Global Approach to Fighting Health Disparities

Wednesday, June 16, 2021

Dr. Charles Rotimi

IRP distinguished investigator Charles Rotimi, Ph.D., was elected to the American Academy of Arts and Sciences this year in recognition of his pioneering work exploring the health implications of genetic diversity in populations with African ancestry, as well as for globalizing the study of genomics, particularly in African nations. Dr. Rotimi joined NIH in 2008 as the founding director of the Intramural Center for Genomics and Health Disparities in the National Human Genome Research Institute (NHGRI), which was later renamed the Center for Research on Genomics and Global Health, in part to reflect Dr. Rotimi’s globe-spanning research programs.

Attempting Weight Loss Linked to Reduced Risk of Death

IRP Research Overturns Common Concerns About ‘Weight Cycling’

Tuesday, December 8, 2020

With 2021 less than a month away, many of the more than 200 million Americans who are overweight or obese are beginning to consider making weight loss their New Year’s resolutions — perhaps not for the first time. While trying to lose weight only to ultimately regain it may be disappointing, a new IRP study suggests that repeated attempts at weight loss significantly reduce a person’s risk of dying.
