Talks highlight recently published work in JAMA and NEJM

from Sonja K. Billes

During a special session Friday afternoon, authors of papers published in special obesity-themed issues of JAMA (provided with the TOS final program) and NEJM, presented their work.

Three papers were presented from the September 19 edition of JAMA. Dr. Adams presented data on the health benefits of gastric bypass surgery after 6 years, showing that gastric bypass surgery was associated with long-term remission of diabetes, hypertension and abnormal lipids. Dr. Davis presented evidence showing that even 20 minutes of vigorous exercise per day without any dietary restriction is sufficient to reduce diabetes risk in overweight and obese children, and produced a dose-dependent reduction in fatness. Dr. Neeland presented work demonstrating an association between visceral fat and weight gain (most likely gain of visceral fat) among those already obese and incident prediabetes and type 2 diabetes. Additionally, factors that contribute to cardiovascular disease were present well before diabetes diagnosis. Talks from the September 21 issue of NEJM continued Friday's discussion of the role of sugar-sweetened beverages (SSBs) in obesity. Dr. Qi presented data showing that high genetic risk for obesity exaggerates the association between SSB consumption and BMI. Dr. Katan and Dr. Ebbeling showed that reducing consumption of SSBs among children and adolescents is associated with reduced total caloric intake and slower weight gain.

Dr. Livingston, who edited this week's edition of JAMA, stated that the high degree (93 percent) and length of follow up in the study presented by Dr. Adams are common characteristics of the type of study that appeals to editors in high profile medical journals. more
