True/False Questions

  1. Overweight and obesity are responsible for 2.8 million deaths annually, ranking fifth among the top ten leading causes of death worldwide.
  2. In 2017, approximately 700 million adults were obese in the world population.
  3. Globally, the number of overweight children under 5 years of age increased from 20 million in 2005 to 43 million in 2010.
  4. The prevalence of obesity in women exceeds that in men by 5-10% at all ages.
  5. The prevalence of obesity is up to 10-fold higher in populations residing in urban areas than in rural areas.
  6. In the USA, the prevalence of obesity now exceeds 30%.
  7. In the USA, the steep rise in childhood obesity has paralleled the epidemic rise in adult obesity.
  8. In the USA, the highest prevalence of obesity is found in Caucasian women.
  9. Obesity has been found to exert deleterious effects on nearly every organ system of the body.
  10. Studies conducted in the USA suggest that obesity accounts for up to 70% of type 2 diabetes.
  11. A meta-analysis of 21 prospective cohort studies found that obesity increases the risk of cardiovascular disease by 81%.
  12. The INTERHEART Study confirmed that elevated BMI is a better predictor of impending heart attack than elevated waist to hip ratio.
  13. A US study found that obesity accounts for 14-20% of cancer mortality.
  14. Obesity is inversely related to CRP level.
  15. Inflammatory adipokines have been etiologically linked to atherogenesis.
  16. Childhood obesity rarely tracks to adult obesity in the same individual.
  17. The number of fat cells (adipocytes) fluctuates widely in adults.
  18. The size of fat cells (adipocytes) fluctuates widely in adults depending upon storage of triacylglycerol for energy reserve.
  19. Major genetic shifts are undoubtedly responsible for the increasing rates of obesity in most populations.
  20. Bariatric surgery to reduce gastric capacity has proven to be effective in the treatment of morbid obesity in some patients.
