AOR was derived from multivariable logistic regression model mutually adjusted for all other sociodemographic factors.

COR was derived from bivariate logistic regression model.

Bolded values are two-sided p values<0.05.

*Overall p value.

†Of all participants, 21.5% did not provide information on their average monthly household income. They have been categorised as ‘unknown income’ and included for analysis.

AOR, adjusted OR; COR, crude OR; SGD, Singapore Dollar.
