Discrimination or Shaming Doesn’t Encourage Weight Loss
(Obesity)


Discrimination against people with obesity does not help them to lose weight, according to new research published in the journal Obesity. In a study of 2,944 UK adults over four years, those who reported experiencing weight discrimination gained more weight than those who did not. On average, after accounting for baseline differences, people who reported weight discrimination gained 0.95kg. Those who did not lost 0.71kg, a difference of 1.66kg. The data is from the English Longitudinal Study of Aging, a study of adults aged 50 or older.


Morbidity, Mortality, and Weight Loss Outcomes After Reoperative Bariatric Surgery in the USA
(Journal of Gastrointestinal Surgery)


Most bariatric surgery patients do not need reoperations. However, among the 6.3% of patients that do, the complication rate is low and outcomes are clinically comparable to primary procedures, according to a new study published online first in the September edition of the Journal of Gastrointestinal Surgery. The data from nearly 450,000 operations was culled from the Bariatric Outcomes Longitudinal Database. The authors noted comorbidities were resolved after both primary operations and reoperations.


Changes in Bariatric Surgery Procedure Use in Michigan, 2006-2013 (JAMA)


Michigan researchers say sleeve gastrectomy procedures have surpassed gastric bypass procedures in 2012. The data was compiled from the 39-hospital Michigan Bariatric Surgery Collaborative between 2006 and 2013. The researchers found that sleeve gastrectomy increased from 6% of all procedures in 2008 to 67.3% of all procedures in 2013. Gastric bypass decreased from 58% to 27.4 percent during the same period. Gastric banding decreased
from 34.5% to 4.6%.


Gastric Banding Linked to Mycobacterium Infections
(Emerging Infectious Diseases -- Online)


Australian researchers say the rise in mycobacterium infections may be linked to gastric banding surgery, but no clear source has been identified. The study identified 18 cases of infection caused by Mycobacterium fortuitum and Mycobacterium abscessus that were linked to gastric banding in Australia between 2005 and 2011. The port appeared to be the primary site of infection in more than half the patients. Five cases or 28% were linked
to the band.


Social Networking Strategies that Aim to Reduce Obesity Have Achieved Significant Although Modest Results (Health Affairs)


A systematic review and meta-analysis assessing the role of social networking services found “a modest but significant 0.64% reduction in BMI for the 941 people who participated in social networking interventions.” Researchers recommend social networking services that target obesity should be the subject of future clinical trials and that policy makers adopt reforms that promote the use of anti-obesity social networking services.
