Predictors of Weight Change in Male HIV-Positive Injection Drug Users Initiating Antiretroviral Therapy in Hanoi, Vietnam

Table 4

Coefficients derived from final multivariate model predicting weight change, accounting for effect modification by Interval.

	Difference in weight change (β) ± SE (P-value)		P-value for interaction term
	Interval 1	Interval 2
Intercept	−2.7 ± 1.8 (.14)	4.1 ± 0.9 (<.001)	0.001
CD4 <200 cells/μL (yes/no)	3.5 ±1.5 (.03)	−3.0 ± 0.7 (<.001)	<0.001
Adherence to HIV meds (Excellent/Very Good versus Good/Fair/Poor)	3.0 ± 0.9 (.002)	−0.01 ± 0.7 (.98)	0.01
Nausea (yes/no)	2.2 ± 0.8 (.006)	−1.3 ± 0.8 (.13)	0.005
Moderate/Heavy Drinker (yes/no)	−2.6 ± 1.0 (.02)	−0.02 ± 0.8 (.98)	0.06
Liquid supplements (yes/no)	2.6 ± 1.0 (.01)	−1.3 ± 1.5 (.39)	0.05
Tobacco smoking	−1.2 ± 0.5 (.02)		0.17

Interaction term (Tobacco smoking * Interval) was dropped from the final model due to nonsignificant P-value. Coefficient shown is from main effect of tobacco smoking only.
