How people view their own weight influences bariatric surgery success
Patients with less internalized weight bias experience greater weight loss success

(Press-News.org) Negative feelings about one's own weight, known as internalized weight bias, influence the success people have after undergoing weight loss surgery, according to research appearing in the journal Obesity Surgery, published by Springer. The study, from the Geisinger Health System in the US, is considered the first and only study to examine internalized weight bias in relation to post-surgical weight loss success in adults.
Internalized weight bias adversely affects many overweight people. Studies have shown that weight bias stems from personal perception or societal views that overweight people are personally accountable and at fault for their body weight. These overweight individuals feel - or think others feel - they lack the willpower, discipline and treatment needed to lose weight. In addition, people who are highly vulnerable to negative feelings about their own weight are more likely to experience low self-esteem and depression.
In this study, the researchers measured the degree to which participants internalized weight bias by developing negative self-attributions as a result of these biases. They leveraged Geisinger's electronic health record and its existing bariatric surgery database along with psychological surveys. The result: As ratings of internalized weight bias before surgery increased, weight loss success twelve months after surgery decreased.
The researchers found no differences in ratings of bias between participants' race or geographic location (urban or rural) but identified high levels of internal negative thoughts and feelings in about 40 percent of preoperative participants. In addition, greater weight bias was associated with greater depression. On average, most participants were white females with a preoperative mean BMI of 47.8 kg/m² and a postoperative BMI of 32.5±6.1 kg/m² twelve months after surgery.
Clinically, the study suggests a potential benefit to pre-operative weight bias screening. Identifying an opportunity to provide coping strategies, including counseling and peer support group participation, may help to foster long-term weight loss surgery success.
"How an individual internalizes weight bias relates to depression before surgery as well as overall weight loss success twelve months following bariatric surgery," says Michelle R. Lent, Ph.D., Investigator and Clinical Psychologist at Geisinger's Obesity Institute. "Future studies should assess the impact of early weight bias screening and intervention to promote better psychological health and weight loss results."

EAST LANSING, Mich. — Some scientists share better than others. While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go.
Research by Michigan State University, published in the current issue of Bioscience, explores the paradox that although ecologists share findings via scientific journals, they do not share the data on which the studies are built, said Patricia Soranno, MSU fisheries and wildlife professor and co-author of the paper.
"One reason for not sharing data is the fear of being scooped by another scientist; ...

HOUSTON – (Oct. 22, 2014) – Is there an "immigration crisis" on the U.S.-Mexico border? Not according to an examination of historical immigration data, according to a new paper from Rice University's Baker Institute for Public Policy.
"'Illegal' Immigration on the U.S.-Mexico Border: Is it Really a Crisis?" was co-authored by William Gruben, a research associate at the Federal Reserve Bank of Dallas' Globalization and Monetary Policy Institute, and Tony Payan, the Baker Institute's Françoise and Edward Djerejian Fellow for Mexico Studies and director ...

A start-up company in Scotland is working to capitalize on the tons of waste produced by one of the country's most valued industries and turn the dregs of whisky-making into fuel. Celtic Renewables, formed in 2011, has refined its process based on a century-old fermentation technique and is now taking the next step toward a commercial plant, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
Ann M. Thayer, a senior correspondent with C&EN, points out that making whisky requires three ingredients: water, ...

Just in time for flu season, a new Michigan State University study of "the mother of all pandemics" could offer insight into infection control measures for the flu and other epidemic diseases.
Siddharth Chandra, director of MSU's Asian Studies Center and professor in MSU's James Madison College, and Eva Kassens-Noor, assistant professor of urban and transport planning with a joint appointment in the Global Urban Studies Program, studied the evolution of the 1918 influenza pandemic, aka the "Spanish flu." In 1918, the virus killed 50 million people worldwide, 10 to 20 ...

BOZEMAN, Mont. – A team of researchers including Montana State University professor Selena Ahmed has found that shifting patterns of precipitation affect key chemicals responsible for the flavor and health properties of tea.
Ahmed, assistant professor of health and human performance in the MSU College of Education, Health and Human Development, said the team's research shows that major antioxidant compounds that determine tea health properties and flavor, including epigallocatechin, epigallocatechin gallate, epicatechin gallate, gallocatechin gallate, catechin ...

Taking steps from an early age to improve childhood education skills could raise overall population levels of academic achievement by as much as 5%, and reduce socioeconomic inequality in education by 15%, according to international research led by the University of Adelaide.
In a study now published in the journal Child Development, researchers from the University of Adelaide's School of Population Health and colleagues at the University of Bristol in the UK have modelled the likely outcomes of interventions to improve academic skills in children up to school age. They ...

Philadelphia, Oct. 22, 2014 – New work by a pioneering scientist details how subtle changes in mitochondrial function may cause a broad range of common metabolic and degenerative diseases. Mitochondria are tiny energy-producing structures within our cells that contain their own DNA.
The new research shows that small changes in the ratio of mutant to normal mitochondrial DNA within the thousands of mitochondrial DNAs inside each cell can cause abrupt changes in the expression of numerous genes within the nuclear DNA. Furthermore, the different proportions of mutant ...

Using loan level data matched to consumer credit records, researchers have been able to determine that a reduction in mortgage payments of as little as $150 a month spurred a reduction in mortgage defaults and an increase in consumer spending (particularly the financing of automobile purchases), while improving household credit ratings.
University of Chicago Booth School of Business Professor Amit Seru, together with Benjamin J. Key of UChicago's Harris School of Public Policy, Tomasz Piskorski of the Columbia Business School and Vincent Yao of Fannie Mae authored "Mortgage ...

New Rochelle, NY, October 22, 2014—A panel of leading clinicians and researchers across various general and specialty pediatric fields developed a consensus statement recommending how to evaluate youngsters in whom neuropsychiatric symptoms suddenly develop, including the abrupt, dramatic onset of obsessive-compulsive disorder (OCD). This difficult diagnosis is typically made by pediatricians or other primary care clinicians and child psychiatrists, who will benefit from the guidance provided in the recommendations published in Journal of Child and Adolescent Psychopharmacology, ...

Researchers from Princeton University and other institutions may have hit upon an answer to a climate-change puzzle that has eluded scientists for years, and that could help understand the future availability of water for hundreds of millions of people.
In a phenomenon known as the "Karakoram anomaly," glaciers in the Karakoram mountains, a range within the Himalayas, have remained stable and even increased in mass while many glaciers nearby — and worldwide — have receded during the past 150 years, particularly in recent decades. Himalayan glaciers provide ...
