Childhood obesity is a major cause for concern. A study in Pediatric Obesity looked at the prevalence of obesity in pre-schoolers (ages 3-5 yrs) in the US. Overall, 10-12% of over 42000 children had a BMI >/= 95th centile, with 1.6% being severely obese.
It is considered important to limit gestational weight gain to recommended levels. Some interventions are based on theoretical basis, and others are not. Controversy surounds the relative effectiveness of these approaches. A systematic review in Obesity Reviews found similar effectiveness overall between the types of intervention.
Bariatric surgery does not reduce overall health care costs in the long term, according to an analysis of 29,820 patients who had bariatric surgery and an equal number of non-surgical obese individuals between 2002 and 2008 in the US. The paper was published in the journal JAMA Surgery (formerly Archives of Surgery).
A review of the landmark Swedish Obese Subjects trial suggests that Bariatric Surgery Guidelines need to be updated to reflect metabolic status of patients, particularly glucose/insulin levels, not just body mass index (BMI). Bariatric News had an article on this, and the original paper appeared in the Journal of Internal Medicine.
The Body Mass Index is a flawed concept. Read about it on the BBC's website, or go in-depth into the statistics on Prof Trefethen's explanation on the Oxford University site.
