The only groups to experience a significant change in obesity status were children aged 2 to 5 years, who saw a decrease from 13.9% to 8.4% (P=0.03), and women aged 60 years and older with an increase in prevalence from 31.5% to 38.1% (P =0.006), the researchers found.

“Obesity prevalence remains high and thus it is important to continue surveillance,” they wrote.
