In a word, yes. I am certainly no covid authority, but I do have regular conversations with the chief of pulmonary ICU at my hospital (which is the biggest hospital in the second worst hit city in the states, so no shortage of experience). Her experience (anecdotal, obviously) is that obesity is probably among the worst predictors of bad outcomes. Kidney disease is also a particularly bad one. Many patients on vents progress to kidney disease and require dialysis, so if one comes in ahead of that curve, it's a really bad sign. Diabetes, obviously, is correlated with obesity, heart disease, kidney disease, and many other conditions. So diabetes is one of the worst things, since the more co-morbid conditions one has, the worse their prognosis. Unfortunately, in the inner cities in America, diabetes is ubiquitous. And the people who have diabetes are the most likely to be poor, to be unable to "shelter in place", and to have irregular (or any) healthcare visits in normal times. All of these factors will likely lead to higher transmission rates and worse outcomes per case than in the healthier suburbs. I suspect on average the numbers in the states will look like Europe in a lot of ways, but the difference will be that there will be a stark bifurcation between cities and suburbs (which is basically always the case in America--the rich areas have as good or better health outcomes as anywhere in the world, whereas the poor areas are like 3rd world countries).
