MedicalResearch: What are the main findings of the study?

Answer: Globally, obesity has become a public health epidemic. Obesity is affecting not just developed countries, but developing countries as well. Almost one-third of the world’s population, over 2 billion people, are considered to be overweight or obese. Of this group, nearly two-thirds (62%) are in developing countries. If current trends continue, this number will continue to rise. Between 1980 and 2013, the prevalence of overweight or obesity for children and adolescents increased by nearly 50%. This study is the first analysis of global trends on obesity and covers more than 30 years and 188 countries.

MedicalResearch: Were any of the findings unexpected?

Answer: It was especially troubling to see that no country has successfully decreased obesity rates over the last 33 years. One small bright spot: we have seen slower growth rates of overweight and obesity trends in developed countries. More than 50% of the world’s obese population lives in 10 countries; the United States has the most obese people, followed by China, India, Russia, Brazil, Mexico, Egypt, Germany, Pakistan, and Indonesia. This is not entirely due to population size, as the disease burden of overweight and obese populations does not correlate to the general country population. The US alone accounts for 13% of the world’s obese population but only 5% of the total world population. Several countries in the Middle East showed the largest increase in obesity rates over the 33-year period of research, including Bahrain, Egypt, Saudi Arabia, Oman, and Kuwait.

MedicalResearch: What should clinicians and patients take away from your report?

Answer: Worldwide, over 2 billion people are overweight or obese. It is increasingly evident that our current methods to address overweight and obesity are ineffective. With increases in obesity come increased health problems, such as chronic kidney disease, cancer, and diabetes. The sharp increase in rates of overweight and obesity in children and adolescents is an indicator of our lack of progress. In order to create healthier future generations, we need to address these troubling results.

MedicalResearch: What recommendations do you have for future research as a result of this study?

Answer: We hope that policymakers and agenda-setters will use this information to better improve current health interventions and create specific targets for combating this issue. Studies of local patterns of obesity are needed to generate solutions that can be tailored to communities. Obesity may be a global problem, but it needs to be approached locally, starting with researching how to create strategies that can address the complexity of cultural traditions and dietary norms across the world.
