The mediation analysis were adjusted for basic information-age, gender, years of education, daily use of electronic devices such as mobile phones, pads, and computers for entertainment, total household income, body mass index, exercise, rapid screening for depression, anxiety screening, and disease course. CI: Confidence interval; SSRS: Social support rating scale.
