(Press-News.org) LEBANON, NH - A health promotion program, called In SHAPE, specifically designed for people with serious mental illness, produced more fit participants and significant weight loss than a control group where participants only received a gym membership.
The results of a randomized clinical trial, published in the Dec. 12 American Journal of Psychiatry, Dr. Stephen Bartels of Dartmouth and colleagues showed that more than half the participants in the In SHAPE group achieved clinically significant reduction in cardiovascular risk. These positive outcomes were maintained six months after the In SHAPE program ended.
"Upwards of 80 percent of people with serious mental illness are overweight or obese, and rates of obesity among people with serious mental illness are nearly double the rate within the general population, which represents an alarming public health concern," said Bartels of the Dartmouth Centers for Health and Aging.
In SHAPE is a 12-month health promotion program consisting of a gym membership and a health promotion coach for people with serious mental illness. Participants have weekly individual meetings with their coach who is trained as a personal fitness trainer and who has received instruction in healthy eating and nutrition.
The health promotion coach is a key component of the In SHAPE program. The instructors receive one-week training where they receive instruction in motivational interviewing, fitness goal setting, healthy nutrition, strategies for health behavior change, and tracking eating and physical activity behaviors.
The In SHAPE program was first developed in 2004 in New Hampshire and has been previously evaluated in a 2013 randomized controlled trial.
This replication study achieved results comparable to the 2013 randomized control trial, which showed 49 percent reduction in cardiovascular risk in In SHAPE participants with serious mental illness within a community mental health center in a predominantly white setting in New Hampshire.
The current study demonstrated that the In SHAPE program achieved and exceeded the same clinically meaningful benefits across multiple community mental health providers, in greater Boston, MA, and within an ethnically heterogeneous sample where 46 percent of participants were nonwhite.
This is important in behavioral health research because it is very challenging to replicate study results across different settings.
One of the main surprises of the study was the finding of maintenance of clinically significant reductions in cardiovascular risk six months after the intervention was removed. (Cardiovascular risk is defined as clinically meaningful weight loss of 5 percent or more or clinically significant improved fitness.) Another surprise was that the findings replicated and exceeded the positive findings of a prior randomized controlled trial of this same intervention.
A limitation of this study is that the sample size was not large enough (210 participants) to determine whether there were differences in weight loss between different psychiatric diagnoses or between different racial or ethnic groups.
In this study, serious mental illness included schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder.

Together, the Dartmouth Centers for Health & Aging, funded through a combination of federal grants, foundation grants, philanthropic donations, and institutional support from The Dartmouth Institute for Health Policy & Clinical Practice, The Geisel School of Medicine at Dartmouth, and the Dartmouth Hitchcock Medical Center, work to improve the mental and physical health and quality of life of adults as they age and their families.
When designing a new car, manufacturers might try to attract consumers with more horsepower, increased fuel efficiency or a lower price point. But new research from San Francisco State University shows consumers' loyalty and passion for an automobile brand are driven more by appearance. Aesthetics that resonate on an emotional level are more responsible for brand loyalty than such factors as functionality and price, the study found.
"In product design, if you focus more on the aesthetics of the product, the connections that you create with the consumer at the brand level ...
Stepping on the scale is common among dieters but how does the frequency of weigh-ins impact weight? A new study in PLOS ONE showed that the more frequently dieters weighed themselves the more weight they lost, and if participants went more than a week without weighing themselves, they gained weight.
The researchers analyzed 2,838 weight measurements (up to a years' worth of weigh-ins) from 40 overweight individuals (with a body mass index of 25 and over) who indicated that weight loss was a personal goal or concern. The researchers found that weight loss was related ...
DENVER - Next generation sequencing in malignant pleural mesothelioma (MPM) tumors shows a complex mutational setting with a high number of genetic alterations in genes involved in DNA repair, cell survival and cell proliferation pathways. Increased accumulation of mutations correlates with early progression of the tumor and decreased survival.
MPM is a fatal cancer associated with asbestos exposure that develops on the outer linings of the lungs. The 3-year survival rate is only 8% and most MPM patients are diagnosed with late stage disease with limited therapeutic options. ...
DENVER - A prospective nationwide survey on perceptions of lung cancer in the general population of France highlights a need for increased public education on the benefits of lung cancer screening, the good survival rates of early-stage disease and the improved outcomes with new therapeutic strategies, including targeted-therapies.
Lung cancer management in recent years has improved patient outcomes because of screening, improved surgery and radiotherapy in early and locally-advanced stages of disease, new chemotherapies, validated maintenance therapy, and effective targeted ...
High-energy jets powered by supermassive black holes can blast away a galaxy's star-forming fuel, resulting in so-called "red and dead" galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones.
Now astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that black holes don't have to be nearly so powerful to shut down star formation. By observing the dust and gas at the center of NGC 1266, a nearby lenticular galaxy with a relatively modest central black hole, the astronomers have detected ...
BELLINGHAM, Washington, USA - The first issue of the new Journal of Astronomical Telescopes, Instruments, and Systems (JATIS) has been launched by SPIE, the international society for optics and photonics. All articles will be freely available through the end of 2015 in the SPIE Digital Library. Mark Clampin, SPIE Fellow and James Webb Space Telescope Observatory Project Scientist at NASA Goddard Space Flight Center, is editor-in-chief.
"A key motivation for the creation of this journal has been the continuing success of SPIE's Instrumentation in Astronomy conference ...

Johns Hopkins researchers have developed a sugar-based molecular microcapsule that eliminates the toxicity of an anticancer agent developed a decade ago at Johns Hopkins, called 3-bromopyruvate, or 3BrPA, in studies of mice with implants of human pancreatic cancer tissue. The encapsulated drug packed a potent anticancer punch, stopping the progression of tumors in the mice, but without the usual toxic effects.
"We developed 3BrPA to target a hallmark of cancer cells, namely their increased dependency on glucose compared with normal cells. But the nonencapsulated drug ...
In a development that holds promise for future magnetic memory and logic devices, researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and Cornell University successfully used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature. This demonstration, which runs counter to conventional scientific wisdom, points a new way towards spintronics and smaller, faster and cheaper ways of storing and processing data.
"Our work shows that 180-degree magnetization switching ...
Premature ovarian failure, also known as primary ovarian insufficiency (POI), affects 1% of all women worldwide. In most cases, the exact cause of the condition, which is often associated with infertility, is difficult to determine.
A new Tel Aviv University study throws a spotlight on a previously-unidentified cause of POI: a unique mutation in a gene called SYCE1 that has not been previously associated with POI in humans. The research, published in the Journal of Clinical Endocrinology and Metabolism, was led by Dr. Liat de Vries and Prof. Lina Basel-Vanagaite of TAU's ...
