Note: Comparable models as those shown in Table 3 except restricted to respondents ages 35–54 at baseline in 1986. The first two rows of results indicate models in which each measure of SES was evaluated without adjustment for the other. Joint models include both measures of SES. The reference category for education is 16+ years of schooling. The reference category for income is $30,000+. Behaviors assessed were cigarette smoking, physical activity, BMI, and alcohol use. Percent explanations are based on percentage reduction of the excess risks (HR-1.00) in the base model compared to the fixed and time-varying behavioral models, respectively. All models were adjusted for age, sex, and race. All models were adjusted for age, sex, and race. There were 218 deaths between 1986–2011. Results reflect sample weighting.
