For the bivariable analysis, only significant results are shown. The level of significance was set at p < 0.05. Seven demographic variables (age, city of residence, education level, employment status, monthly income, sexual orientation, and living status) were controlled for in the final multivariable regression model.

^*p < 0.05, ^**p < 0.01, ^***p < 0.001.

aOR, adjusted odds ratio; CI, confidence interval; SD, standard deviation.
