If you look at your JAMA article, you'll see that the connection between antibiotic use and childhood obesity is pretty small. My question would be, we've had broad-spectrum antibiotics around since WW2 (broad spectrum being the one the paper flags), yet obesity is a relatively recent phenomenon.

Also, they also found a connection between obesity and "Steroid use, male sex, urban practice, public insurance, Hispanic ethnicity, and diagnosed asthma or wheezing were also predictors of obesity; common infectious diagnoses and antireflux medications were not."
