Control variables include the following: at individual-level, household size and its squared term, number of children and its squared term, 5-year interval age indicators, gender (when pooled), marital status, education, employment, income, race, interview month; at county/local health department level, health department organization, county urbanization code, county-level median household income variable; and an indicator of year 2005 (baseline: year 2004).
The model used is a multilevel logistic regression with three levels: individual, county, and state. State specific intercepts are assumed to be fixed.
CE, coefficient estimate; DV, dependent variable; PM, predicted marginal (calculated as the difference in the changes of the predicted probabilities of [morbid] obesity from 2004 to 2005 between those residing in counties with a positive response to q67a and those residing in counties with a negative response).
