Table 3

Multilevel logistic regression models of area SES (strata) and overall physical activity, walking, cycling, jogging, and swimming with and without adjustment for individual SES (income, occupation, education)

	Overall physical activity		Walking		Cycling		Jogging		Swimming
	OR	95% CI	OR	95% CI	OR	95% CI	OR	95% CI	OR	95% CI
Model 1, the null model includes area level variance adjusted for age and sex. Model 2, adds individual SES (household income, occupation, education) to age and sex as in model 1. Model 3, adds strata (SES area) to age and sex as in model 1. Model 4, includes age, sex, individual SES, and area SES.
