I have Bayes on the phone, he says "What percentage of teens in the American south are obese?"

  21.2% in 12-19 range, according to the CDC, so certainly overrepresented. https://www.cdc.gov/obesity/data/childhood.html https://www.cdc.gov/obesity/data/childhood.html

    Note that obesity rates (significantly) throughout the country and a significant part of the south is in the "more obese" region ("above 40%" https://www.cdc.gov/obesity/data/prevalence-maps.html https://www.cdc.gov/obesity/data/prevalence-maps.html) so the national average can't be used to determine if the sample was overrepresented.

      I get that there can be confounders on how you interpret it, but nothing about this statement seems improper or incorrect: "In America obesity is overrepresented in teenagers hospitalized with Covid-19."

        if the study was done in a population that is elevated in obesity (for example in the south) then you wouldn't be able to generalize it to the national population.

          While true that one can't say for sure, the link you provided gives a 95% CI that's still pretty close to 40%. I'd wager the chance of randomly picking 6 hospitals whose obesity rate way further than 4-5 sigma away the mean would be pretty damn small.
