Obesity epidemic is one of the most acute problems of world health.
The number of people with overweight continues to increase every year. To date, approximately 22-23% of the world’s population has overweight or obesity.
By nature and speed of spread, obesity becomes epidemic, especially in developing or developed countries. Epidemiologists say that the number of obese people will be able to increase to about 575 million by 2030.
The results of statistical studies prove that in the USA the number of obese people decreased by about 4% (38% to 34%) from 2014 to 2016. Nevertheless, today about 75% of adult Americans are obese or overweight. Most obese people live in the state of Louisiana – more than 35% of the population.
In total, more than 77 million Americans have BMI above 30 kg / m2, including:
- elderly – about 36%
- high school students – about 15%
- young people between 20 and 39 years old – over 30%
- adults from 40 to 60 years – less than 41%
- children of young age (2-5 years) – about 2%.
Australia takes the second place in the prevalence of obesity epidemic today. More than 60% of adult Australians and about 25% of children living in Australia have BMI above 30 kg / m2.
In European countries, annual growth of the obesity epidemic varies between 6%-37% in women and 4%-29% in men. In Europe, there are approximately 15 million obese children and about 150 million adults with obesity.
Collection and analysis of statistical data on the obesity prevalence in the world helps to choose the most appropriate strategies to prevent its further spread.
