The findings are from an analysis of 8015 emerging adults aged 18-25 in the cross-sectional National Health and Nutrition Examination Survey (NHANES), including NHANES II (1976-1980), NHANES III (1988-1994), and the continuous NHANES cycles from 1999 through 2018. The prevalence of obesity (BMI 30.0 kg/m2 or higher) in the emerging adult age group soared from 6.2% between 1976-1980 to 32.7% in 2017-2018 (P = .007).

I really need to finish writing my Future Best Seller.

It certainly is no surprise. If you look at documentaries showing lots of young adults in the 50s 60s and 70s, they are much thinner than the young adults today.
I live in Oklahoma where some humans are quite large. I’m sure if I watched older documentaries I would be shocked as well. Not surprised. Shocked.
Me too! I am watching a documentary right now that takes place in the early 1960s. And the difference in body mass when they switch to the present time is extraordinary.
Again, travel Oklahoma or Kansas and your lack of surprise may turn to shock when you see the sheer size of some humans!
I’ll bet it’s pretty similar to Northwest Florida.
