Abbreviation: aOR = adjusted odds ratio; MSA = metropolitan statistical area; OR = unadjusted odds ratio; Ref = referent group.
* Prevalence adjusted for population weights, clusters, and stratification following National Health Interview Survey analytic guidelines.
† Adjusted for biological sex, age, race and ethnicity, education, and income-to-poverty threshold.
§ Nonmetropolitan = micropolitan counties (counties in micropolitan statistical areas) and noncore counties (counties that did not qualify as micropolitan); medium metro = counties in MSAs of populations of 250,000–999,999; small metro = counties in MSAs of populations less than 250,000; large fringe metro = counties in MSAs of 1 million or more population that did not qualify as large central metro counties; large central metro = counties in MSAs of 1 million or more population that 1) contain the entire population of the largest principal city of the MSA, or 2) have their entire population contained in the largest principal city of the MSA, or 3) contain at least 250,000 inhabitants of any principal city of the MSA. https://www.cdc.gov/nchs/data/series/sr_02/sr02_166.pdf
