According to the World Health Organisation, Ireland set to be most overweight country in Europe by 2030. Developed countries in general, and Europe in particular, are experiencing alarmingly high rates of overweight populations and obesity, and Ireland is set to be at the forefront of this issue over the next few decades.

Let's dive into a brief analysis of the evolution of our weight problems, while also looking at some other countries across the globe.

How The Overweight Population has Changed Globally

#How-The-Overweight-Population-has-Changed-Globally

The graphs below provide first a snapshot of the national prevelence of overweight adults around the world, where overweight is defined as one having a BMI greater than 25 (age-standardised estimate), and second, the situation 25 years later, in 2016. What do we know?

  • The most startling increase in overweight prevalence comes from the US, from 50.9% in 1991 to 68% in 2016.
  • Countries in the Middle East, like Saudi Arabia, Iraq and Iran, have also experienced massive increases. This is likely due to the unhealthy American legacy in the region , particularly pertaining to fast-food, and growing economies.
  • Ireland is now one of the fattest countires in Europe.

Evolution of Overweight Rates

#Evolution-of-Overweight-Rates

Now let's take a look at the overweight rates over time for a few select countries.

  • Ireland and the US have had some of the steepest increases in overweight rates.

  • Ireland's overweight rate among adults has grown by 26% precentage points.

  • Nauru, like many small, former colonies, sees consistently high rates of obesity. Overweight populations in the Pacific islands are often seen as this colonial legacy of settlers trying to civilize the locals.

By Gender - Select Countries

#By-Gender---Select-Countries
  • Overweight rates have been rising for both genders for all countries under analysis.

  • For developed countries like the US, Ireland, Italy and Spain the rate of overweight women has consistently trailed that of men, although both have been rising in near lockstep.

  • The overweight populaiton rate in Nauru, although extremely high among both men and women, is significantly higher among women through time.
