^aAdjusted for all other covariates in the model.

^bAOR associated with 1 point increase in 7-point scale item, where 0 = least fatalistic and 6 = most fatalistic.

^cAOR associated with 1 point increase in 9-point scale item, where 1 represents the bottom rung of the social ladder tool and 9 represents the top rung.

AOR, adjusted odds ratio; CI, confidence interval.
