Association Between Neighborhood-Level Environmental Variables and Incidence of DSM-IV Nonaffective Psychosis
| Variable (z-standardized)a | Control for | |
|---|---|---|
| Individual-Level Factorsb | Full Multivariatec | |
| RR (95% CI) | RR (95% CI) | |
| IMD | 1.20 (1.00, 1.43) | 1.28 (1.08, 1.51) |
| Income inequality | 1.09 (0.89,1.28) | 1.25 (1.04, 1.49) |
| Population density | 1.15 (0.95, 1.39) | 1.18 (1.00, 1.41) |
| SFI | 1.05 (0.87, 1.26) | 1.08 (0.87, 1.34) |
| Voter turnout | 1.21 (0.98, 1.45) | 1.12 (0.91, 1.35) |
Notes: IMD, index of multiple deprivation; SFI, social fragmentation index.
aRelative Risk (RR) report relative change in incidence associated with a 1 SD increase in value of neighborhood variable.
bAfter indirect standardization for individual-level age group, sex, ethnicity, and socioeconomic status.
cAdditional control for neighborhood-level variables included in final model: IMD, income inequality and population density. SFI & voter turnout not retained in final model given nonsignificance.
