*These factors were available at multiple study visits. For each study visit where these variables were available, we categorized participants as having ideal or non-ideal levels of each of these factors. We then categorized participants as maintaining ideal levels of each factor if participants were in the ideal category at all visits in which they were collected. S1 Table in S1 File lists these study variable definitions, visits at which they were collected, collection methods, and their classification for ideal level status.
