Obesity is currently the most common form of malnutrition in most countries and rates have increased in all categories of men, women, children and adolescents since 1990, as reflected in a study published in ‘The Lancet’.
Obesity rates in adult men have nearly tripled since 1990, while obesity rates in women have doubled in that time. In addition, obesity rates in children and adolescents have also quadrupled in that period. In 2022, nearly 880 million adults and nearly 160 million children were living with obesity.
The prevalence of malnutrition worldwide was shared by the NCD Risk Factor Collaboration, a network of health scientists from around the world who provide and evaluate data on the main risk factors for all countries, in collaboration with the Organization World Health.
The Associate Executive Director of the Department of Population and Public Health Sciences at the Pennington Biomedical Research Center in Baton Rouge (USA), Peter Katzmarzyk, was one of the authors who contributed to this publication.
Participants in the network reviewed body mass index data from more than 3,600 studies conducted between 1990 and 2022, determining rates of malnutrition, whether due to obesity or underweight, across countries, and the degree to which Data has changed over the years.
“Current obesity rates seem overwhelming, but the trend has been going in this direction for more than three decades. With more than one billion people living with obesity, it is important that we do not talk regarding obesity in a vacuum. We know that obesity can directly lead to comorbidities, such as high blood pressure, heart disease, diabetes, cancer, and obstructive sleep apnea. If we better understand the root causes of obesity, we can identify ways to prevent, treat or even reverse its adverse effects,” Katzmarzyk explained.
The US is the tenth country with the most obese men:
Of the more than 190 countries represented in this study, the United States ranks 10th in the world for obesity prevalence in men, with the percentage of men increasing from 17 percent in 1990 to 42 percent in 2022.
In the case of women, the obesity rate in 1990 was 21 percent and increased to 44 percent in 2022, ranking 36th in the world.
For its part, in children, the obesity rate increased from 11.5 percent in 1990 to 22 percent in 2022, which places the US in 26th place in the world. The female obesity rate in the US is the 22nd highest in the world, increasing from 12 percent in 1990 to 19 percent in 2022.
The results echo the prevalence of obesity at granular levels, as in 2020, 38 percent of Louisiana adults face obesity, according to County Health Rankings and Roadmaps.
“The results of this study strongly affirm the value of Pennington Biomedical’s mission,” said Pennington Biomedical CEO John Kirwan, adding that “with the prevalence of obesity increasing over the decades, “We remain steadfast in our commitment to promoting metabolic health, eliminating metabolic diseases, uncovering the triggers of obesity, and improving the health of all people.”
During the same period, rates of underweight children, adolescents and adults fell globally, and in some African countries the rate of underweight men fell dramatically. Both obesity and underweight are forms of malnutrition, and obesity rates are higher than underweight rates in children in two-thirds of the world’s countries.
