Couple-level analysis: HPA (habitual physical activity).
Adjusted for individual level variables, including husband’s and wife’s ages, education years, race/ethnicity, weight status, smoking, individual income, employment status, survey year, indicator of respondent, and missingness indicators.
Testing for cross strata difference in OR, compared to the referent stratum: * < 0.05. (ref): the referent stratum.
