Two co-residing parents graduated from college	0.564	0.606
	(0.451, 0.706)	(0.264, 1.392)

Notes: Confidence interval (CI).

Categories from lowest to highest among those who started out not obese: stayed not obese throughout the waves, started not obese and fluctuated, started not obese and became obese without reverting to not obese.

Categories from lowest to highest among those who started out obese: started obese and became not obese without reverting to obese, started obese and fluctuated, stayed obese throughout the waves.
