Researchers from Boston Youngsters’s Hospital and Harvard Medical College examined nationwide tendencies in physique mass index (BMI) and weight problems charges between 2013 and 2023.

The researchers discovered that adults aged 66 to 75 years and girls additionally skilled notable decreases in weight problems charges.
Lead researcher Dr. Benjamin Rader from Boston Youngsters’s Hospital’s Computational Epidemiology Lab and his colleagues analyzed knowledge from the Optum deidentified Market Readability Knowledge system, which incorporates each medical claims and digital well being information. Their evaluation confirmed that imply inhabitants BMI rose persistently from 2013 till 2021, reached a plateau in 2022 at 30.24, after which decreased barely to 30.21 in 2023.
A very intriguing facet of the findings includes regional variations in using GLP-1RA medicines (like semaglutide). The South confirmed the best fee at 6.0% of sufferers receiving these medicines, in comparison with simply 3.4% within the West.
