Results of Cox proportional hazards regression analyses predicting initiation of marijuana use
| Model 1 HR (95% CI) |
Model 2 HR (95% CI) |
|
|---|---|---|
| Importance of religiona | ||
| Black girlsb | ||
| Initiation of marijuana use ≤ age 15 | 0.80 (0.59–1.09) | 1.38 (1.00–1.91) |
| Initiation of marijuana use ≥ age 16 | 0.95 (0.69–1.32) | |
| White girls | 0.60 (0.46–0.79) | 0.84 (0.63–1.11) |
| Participation in religious activitiesa,c | ||
| Black girls | 0.92 (0.77–1.10) | 1.07 (0.88–1.29) |
| White girls | 0.51 (0.39–0.67) | 0.63 (0.47–0.83) |
| Race: Black compared to White | 0.87 (0.63–1.22) | 0.55 (0.38–0.81) |
| Socioeconomic status indicators | ||
| Household receipt of public assistance | – | 1.05 (0.89–1.24) |
| Single parent headed household | – | 1.07 (0.91–1.26) |
| Primary caregiver education < 12 years | – | 0.92 (0.74–1.13) |
| Neighborhood factors | ||
| Low neighborhood safety | – | 1.00 (0.99–1.01) |
| Community cohesion | – | 1.01 (0.99–1.01) |
| Neighborhood physical disorder | – | 1.04 (0.98–1.11) |
| Low parental monitoring | – | 1.08 (1.02–1.13) |
| Conduct problems | – | 1.28 (1.25–1.30) |
Model 1: importance of religion, participation in religious activities, and race; Model 2: addition of socioeconomic status indicators, neighborhood factors, low parental monitoring, and conduct problems

HR hazard ratio, CI confidence interval
a
Separate estimates generated for Black and White girls, given significant interaction with race
b
Risk period split to adjust for proportional hazards violations in Model 1
c
Religious activities other than service attendance
