According to a study in The Lancet Diabetes and Endocrinology, patients with obesity and type 2 diabetes who had gastric bypass surgery had 75% complete remission rates at one year, compared with the 48% remission rate of those who had sleeve gastrectomy. Using data from 109 participants, the researchers also found that the gastric bypass group had higher total body weight loss, but side effects and complications were similar between the two groups.
Patients recently diagnosed with type 2 diabetes and those not on insulin had higher diabetes remission rates after bariatric surgery, according to a study in PLoS Medicine. The study was conducted by researchers at Orebro University in Sweden.
A recent poll by Gallup found that 28% of Americans reported that they weigh at least 200 pounds between 2010 and 2019, which is four points higher than the survey results between 2001 and 2009. The survey also found that the average weight of an American is 178 pounds, four pounds higher than the previous decade, and fewer Americans want to lose weight, at 54%, down from 59%.
An analysis of federal data and medical literature from 1959 to 2017 found US life expectancy increased from 69.9 to 78.9 over almost six decades, but it has been dropping since 2014 as mortality rises among middle-aged Americans, particularly in economically depressed areas. The increase in mortality was attributed to drug overdoses, suicides, alcohol abuse and diseases such as hypertension and diabetes, according to the study in the Journal of the American Medical Association.
Colorectal cancer patients who were overweight or underweight had a higher risk for death and recurrence than patients with normal weights, according to a study presented by Vita Jaspan, a fourth-year medical student at the NYU School of Medicine, at the ACG Annual Scientific Meeting. "Patients should be counseled to maintain a normal weight prior to and following colorectal cancer diagnosis," Jaspan said.
Researchers have found the flu shot is not as effective in patients with overweight or obesity, putting them at higher risk of contracting the illness. The problem may be that T cells in people with excess weight don't function as well, an issue also seen in the elderly, says University of North Carolina at Chapel Hill professor Melinda Beck.
A study published in the Journal of the American Geriatrics Society examined the effects of diet and exercise on 160 sedentary adults aged 55 and older with at least one cardiovascular disease risk factor and cognitive impairments without dementia. The participants were divided into four groups: those who followed the Dietary Approach to Stop Hypertension diet, those who took part in regular aerobic exercise, patients who did both, and patients who received only an educational intervention; and the study found that the groups that took part in exercise had better executive function at one year than those who did not, and the DASH groups had lower risk of cardiovascular disease.
Women with obesity had worse performance on a working memory test, compared with normal-weight women and women with overweight, according to a study in Eating Behaviors. The same association was not observed in men, but additional research is needed to explore the effect of sex because of the study's design, researchers said.
A study published in the Journal of Bone and Mineral Research found that postmenopausal women who regularly had five hours or less of sleep a night had lower bone mass and were twice as likely to have osteoporosis of the hip and spine, compared with women who slept about seven hours nightly. The researchers used data from 11,084 participants of the Women's Health Initiative Study and found that women who slept for six hours every night had a slightly increased spine and whole-body osteoporosis risk.
Eighty-five percent of Americans ages 18 to 64 who responded to a HealthPocket survey said health care costs are too high, and 51% said they avoided medical care because of an inability to pay for it. Among 1,100 respondents, 91% said medical care costs should be as accessible as prices on a restaurant menu, while 96% said hospitals should disclose costs to patients before treatment, and almost 30% said they have medical debt.
