Table 5.

Class differences relative to the functional users (C3).

Variable	M(SE)
	Light-life users(C1)	All-around users(C2)	Pure life users(C4)
Take C3 as the reference group
Class(x) - Health	0.197 (0.141)	−0.016 (0.163)	−0.066 (0.105)
Class(x) - IIDV	−0.484 (0.072)***	0.017 (0.082)	−0.552 (0.054)***
IIDV - Health	−0.050 (0.015)**	0.003 (0.014)	−0.080 (0.010)***

ICV, SCV, LHV are controlled, and results for one dependent variable control for theother dependent variables (i.e., class differences in health for IIDV).

ICV, Individual characteristic variables; SCV, Social characteristic variables; LHV, Living habits variables; IIDV, Internet information dependence variable.
