Abbreviations: AOR, adjusted odds ratio; CI, confidence interval.
a
Models were adjusted for age, education, income, employment, and race, controlling either for sex or presented as a linear combination by sex. Referent is tertile 1 for all models. Tertile 1 represents the lowest scores for that perceived environmental variable, and tertile 3 represents the highest scores for that variable.
b
As compared to nonbicycling.
c
A significant interaction between this perceived built environment variable and sex was observed (Wald test P < 0.15). The association of this perceived built environment variable with recreation bicycling are presented as a linear combination of coefficients by sex.
d
P < .05.
