Effects of evacuation site on postearthquake depression tendency by three-stage Poisson regression model
| Factors | First stage | Second stage | Third stage | |||
| PR | 95% CI | PR | 95% CI | PR | 95% CI | |
| Evacuation site (rental housing) | 1.42 | 1.03 to 1.95 | 1.60 | 1.16 to 2.20 | 1.51 | 1.09 to 2.09 |
| Age (1-year increase) | 1.03 | 1.00 to 1.06 | 1.03 | 1.00 to 1.06 | ||
| Gender (female) | 1.64 | 1.17 to 2.31 | 1.59 | 1.13 to 2.24 | ||
| History of diabetes (‘yes’) | 3.24 | 1.78 to 5.89 | 3.25 | 1.80 to 5.86 | ||
| IADL(one point increase) | 0.82 | 0.68 to 0.98 | 0.85 | 0.71 to 1.03 | ||
| Cognitive function (deteriorate) | 1.72 | 1.24 to 2.38 | 1.75 | 1.26 to 2.43 | ||
| Social activities (deteriorate) | 1.55 | 1.07 to 2.23 | ||||
Poisson regression analysis was performed with objective (response) values taken as PDT occurrence=1 and non-PDT occurrence=0, and significant items in the univariate analysis as adjustment variables.
IADL, instrumental activities of daily living; PDT, presence of depression tendency; PR, prevalence ratio.
