The Insurers’ Dilemma To insure or exclude coverage for weight loss surgery? Blue Cross & Blue Shield of North Carolina –accept coverage Obese members cost 32% more to cover. Diabetes disappears in 9 of 10 successful surgeries Pharmaceutical costs reduce by 20% in first year after weight loss surgery. Blue Cross of Florida – no coverage Average cost is $25,000 (pressure on premiums) 1% increase in premium, results in 16,000 uninsured.

Relationship between sleep & obesity?
Studies by Eastern Virginia Medical School, Mignot, E., (1989) and Prof. Van Culter, E. (2004) Overweight subjects slept less The less sleep a subject gets, the greater their BMI Changes in hunger proportional to changes in hormone levels. Less sleep>lower leptin level>higher ghrelin -leptin suppresses food intake & stimulates energy expenditure -ghrelin stimulates appetite, fat production & body growth

Media & Childhood Obesity
Study by Young et al. (1996), advertising only affects brand choice. Preference & choice affected by cultural norms. The Kaiser Family Foundation (2004) - media contribution not fully documented or conclusively researched. - Food advertising definitely affects children’s purchases and those of their families.

Conclusion Obesity causes many fatal yet preventable conditions such as diabetes, heart disease, asthma, hypertension, stroke, cancer, sleep apnea and so on. Federal government needs to do more to promote healthy eating & more physical exercise. Media needs to exercise self regulation in content of food ads aimed at children A healthy nation is a wealthy nation
