Latest research shows Ireland's obesity problem is only getting worse

A new study from The Lancet said that this will occur by 2025. Men in Ireland have the highest BMI in Europe.

THE NUMBER OF obese people worldwide has risen from 105 million in 1975 to 641 million in 2014, according to the latest research on body mass index (BMI).

Now the Lancet reports that by 2025, Ireland is set to have the second-highest levels of obese women in Europe (37%) just a percentage point away from the UK (38%), and above Malta (34%).

When it comes to BMI, men in Ireland have the highest BMI in Europe, along with Cyprus and Malta. Women in Moldova have the highest average BMI in Europe.

By comparison, 43% of US women and 45% of US men are predicted to be obese in 2025.

The research shows that the proportion of obese men has more than tripled (3.2% to 10.8%), and the proportion of obese women has more than doubled (6.4% to 14.9%) since 1975.

Meanwhile, the proportion of underweight people fell by around a third in both men (13.8% to 8.8%) and women (14.6% to 9.7%).

A global view

The UK has the third highest average BMI in Europe for women equal to Ireland and the Russian Federation and tenth highest for men along with Greece, Hungary, and Lithuania.

Almost a fifth of the world’s obese adults (118 million) live in just six countries: Australia, Canada, Ireland, New Zealand, UK, and USA. Over a quarter (27.1%; 50 million) of the world’s severely obese people also live in these countries.

Over the past four decades, the world’s population has effectively become on average 1.5kg heavier each decade.

If the rate of obesity continues at this pace, by 2025 roughly a fifth of men (18%) and women (21%) worldwide will be obese, and more than 6% of men and 9% of women will be severely obese.

Low body weight

However, the research shows that excessively low body weight remains a serious public health issue in the world’s poorest regions.

The authors of the study warn that rising obesity “should not overshadow the continuing underweight problem in these poor nations”.

In south Asia, almost a quarter of the population are still underweight, and in central and east Africa levels of underweight still remain higher than 12% in women and 15% in men.

“Over the past 40 years, we have changed from a world in which underweight prevalence was more than double that of obesity, to one in which more people are obese than underweight,” explained senior author Professor Majid Ezzati from the School of Public Health at Imperial College London, London, UK.

If present trends continue, not only will the world not meet the obesity target of halting the rise in the prevalence of obesity at its 2010 level by 2025, but more women will be severely obese than underweight by 2025.

He said that new policies that can slow down and stop the worldwide increase in body weight must be implemented quickly and rigorously evaluated, “including smart food policies and improved health-care training”.

Facts and figures

The findings come from a comprehensive new analysis of the global, regional, and national trends in adult (aged 18 and older) BMI between 1975 and 2014.

Data from 1698 population-based studies, surveys, and reports were pooled, totalling 19.2 million men and women aged 18 years or older from 186 countries. This covered 99% of the world’s population.

The research also showed:

  • Women in Singapore, Japan, and a few European countries including Czech Republic, Belgium, France, and Switzerland had virtually no increase in average BMI over the 40 years.
  • Bosnian and Dutch men and Swiss women have the lowest average BMI in Europe.
  • Island nations in Polynesia and Micronesia have the highest average BMI in the world: 34.8 kg/m² for women and 32.2 kg/m² for men in American Samoa.
  • Timor-Leste, Ethiopia, and Eritrea have the lowest average BMI in the world. 
  • More than a fifth of men in India, Bangladesh, Timor-Leste, Afghanistan, Eritrea, and Ethiopia, and a quarter or more of women in Bangladesh and India are still underweight.
  • Among high-income English-speaking countries, the USA has the highest BMI for both men and women.
  • More than one in four severely obese men and almost one in five severely obese women in the world live in the USA.
