Table 4 Multivariable multinomial logistic regression of SSF usage since COVID-19, Vancouver, Canada (2020)

Characteristic	Model 1b: SSF usage since COVID-19 relative to no change:
	A: Increased usage		B: Decreased usage
	RRR	95% CI	RRR	95% CI
Demographics
Age (/ age < 30)
30–39	1.63	0.48–5.55	0.35	0.08–1.59
≥ 40	1.21	0.34–4.29	0.48	0.11–2.10
Homeless (/housed)^†	1.49	0.53–3.80	1.67	0.44–6.29
Men (/women + non-binary)	0.32	0.10–1.08	0.29	0.07–1.25
Behavioural changes since COVID-19
Used alone more often (/ no change)	1.47	0.57–3.81	2.46	0.71–8.49
Substance use (/ no change)
Increased	7.70	2.73–21.75	1.58	0.36–6.81
Decreased	0.95	0.08–10.96	4.22	0.59–30.0
Model statistic: p < 0.05

Model is estimated with each comparison relative to no change in SSF usage as the reference group
CI confidence interval, RRR relative risk ratio
/ = omitted reference category, *p < 0.05; **p < 0.001, Analytic significance level is set to p = 0.05, ^†refers to the month prior to the baseline questionnaire
