(PhysOrg.com) -- A new study helps untangle how marriage, gender and ethnicity are related to body weight. The study of almost 8,000 men and women will be published in the journal Obesity. http://www.physorg.com/news178914911.html Medicine & Health Tue, 01 Dec 2009 18:35:35 EST news178914911 Americans continue to get heavier. Most weight control methods short of bariatric surgery are generally considered ineffective in preventing obesity or reducing weight. The term energy gap was coined to estimate the change in energy balance (intake and expenditure) behaviors required to achieve and sustain reduced body weight outcomes in individuals and populations. In a commentary published in the November 2009 issue of the Journal of the American Dietetic Association, researchers more precisely clarify the concept of the energy gap (or energy gaps) and discuss how the concept can be properly used as a tool to help understand and address obesity. http://www.physorg.com/news176556009.html Medicine & Health Wed, 04 Nov 2009 11:20:43 EST news176556009 Overweight individuals are not just at greater risk of having sleep-disordered-breathing (SDB), they are also likely to suffer greater consequences, according to new research. http://www.physorg.com/news174197302.html Medicine & Health Thu, 08 Oct 2009 05:30:01 EST news174197302 At least 124,000 new cancers in 2008 in Europe may have been caused by excess body weight, according to estimates from a new modelling study. The proportion of cases of new cancers attributable to a body mass index of 25kg/m2 or more were highest among women and in central European countries such as the Czech Republic, Latvia, Slovenia and Bulgaria. http://www.physorg.com/news172991027.html Medicine & Health Thu, 24 Sep 2009 06:08:30 EST news172991027 Meal replacements in a medically supervised weight loss program are successful in facilitating weight loss, according to a new study conducted at the University of Kentucky.

Programs aimed at tackling childhood obesity, by reducing children's consumption of unhealthy food and drink, are likely to be more effective if they also actively seek to keep children happy in other ways, according to Professor Hung-Hao Chang from National Taiwan University and Professor Rodolfo Nayga from the University of Arkansas in the US. Their findings are published in Springer's Journal of Happiness Studies. http://www.physorg.com/news158927962.html Medicine & Health Tue, 14 Apr 2009 11:39:42 EST news158927962 (PhysOrg.com) -- The prevalence of diabetes is at least twice as high in some ethnic groups as it is in whites, even among people with similar body mass index (BMI) numbers, a large new study finds. http://www.physorg.com/news156615759.html Medicine & Health Wed, 18 Mar 2009 17:23:38 EST news156615759 Unemployment benefits help reduce the negative health-related behaviours often associated with being unemployed. A study published in the open access journal BMC Public Health has found that unemployment benefits recipients are less likely to increase drinking or have changes in weight whilst out of work. http://www.physorg.com/news155550266.html Medicine & Health Fri, 06 Mar 2009 08:24:55 EST news155550266 In a research article published recently by the American Journal of Epidemiology, Oregon Research Institute (ORI) scientist Fuzhong Li, Ph.D., and colleagues show that a high-density of fast food outlets was associated with an increase of 3 pounds in weight and .8 inches in waist circumference among neighborhood residents who frequently ate at those restaurants. In contrast, high-walkability neighborhoods were associated with a decrease of 2.7 pounds in weight and 0.6 inches in waist size among residents who increased their levels of vigorous physical activity during a one-year period. http://www.physorg.com/news155311609.html Medicine & Health Tue, 03 Mar 2009 14:07:16 EST news155311609 A new mathematical model of the physiological regulation of body weight suggests a potential mechanism underlying the difficulty of losing weight, one that includes aspects of two competing hypotheses of weight regulation. In the January issue of Cell Metabolism, Massachusetts General Hospital (MGH) investigators outline a system in which there may be several steady states to which an animal's weight tends to gravitate, rather than a single "set point." http://www.physorg.com/news151158880.html Other Sciences Wed, 14 Jan 2009 12:34:40 EST news151158880 A new randomized, prospective trial has shown that orlistat, a commonly prescribed inhibitor of fat absorption, does not help patients with fatty liver disease (FLD) lose weight, nor does it improve their liver enzymes or insulin resistance. These findings are in the January issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD). http://www.physorg.com/news151088581.html Medicine & Health Tue, 13 Jan 2009 17:03:01 EST news151088581 Obesity affects health in several ways, but new research shows obesity can have minimal impact on ovarian cancer survival. A study by researchers at the University of Alabama at Birmingham (UAB) Comprehensive Cancer Center found ovarian cancer survival rates are the same for obese and non-obese women if their chemotherapy doses are closely matched to individual weight. http://www.physorg.com/news149768781.html Medicine & Health Mon, 29 Dec 2008 10:26:21 EST news149768781 The research was carried out by a team of researchers led by Sharon Herring, MD, MPH, an Assistant Professor of Medicine and Public Health at Temple University. She said, "Compared to normal weight women who accurately assessed their pre-pregnancy weight status, the odds of gaining excessively during pregnancy were increased seven-fold among overweight and obese women who thought they weighed less than they really did. Normal weight women who thought they were overweight had twice the odds of excessive gestational weight gain." http://www.physorg.com/news149169633.html Medicine & Health Mon, 22 Dec 2008 12:00:33 EST news149169633 Individuals with sleep-related breathing disorders appear to burn more calories when resting as their conditions become more severe, according to a report in the December issue of Archives of Otolaryngology -Head & Neck Surgery. http://www.physorg.com/news148583306.html Medicine & Health Mon, 15 Dec 2008 17:08:26 EST news148583306 Genetic mouse models have provided surprising insight into mechanisms linking serotoninergic compounds with the regulation of feeding behavior and body weight. The research, published by Cell Press in the November 26th issue of the journal Neuron, pinpoints a specific group of brain cells that mediate energy balance and may lead to the development of antiobesity drugs with fewer side effects. http://www.physorg.com/news146922799.html Medicine & Health Wed, 26 Nov 2008 11:53:19 EST news146922799 The prevalence of obesity and overweight in the United States coupled by the increased risk of gastrointestinal diseases related to obesity raises serious implications for the health of Americans. Several scientific studies in the August issue of The American Journal of Gastroenterology examine the association between obesity and the risk of colorectal cancer and gastroesophageal reflux disease, or GERD. http://www.physorg.com/news138373835.html Medicine & Health Tue, 19 Aug 2008 14:10:35 EST news138373835 When a person is losing a significant amount of weight, they expect to notice changes in their body. However, they may overlook changes happening in their bones. During weight loss through calorie-restricted diets, bones are being remodeled - breaking down old bone and forming new bone - at an accelerated rate. At the same time, bone density is decreasing, causing increased fragility. http://www.physorg.com/news136481781.html Medicine & Health Mon, 28 Jul 2008 16:36:21 EST news136481781 The peer groups teenage girls identify with determine how they decide to control their own figure. So reports a new study by Dr. Eleanor Mackey from the Children's National Medical Center in Washington DC, and her colleague Dr. Annette La Greca from the University of Miami. Also influencing weight control behavior is girls' own definition of normal body weight and their perception of what others consider normal body weight. These results have just been published online in the Journal of Youth and Adolescence, a Springer publication. http://www.physorg.com/news134129305.html Medicine & Health Tue, 01 Jul 2008 11:08:25 EST news134129305
