Analyses also controlled for the demographic variables listed in Table 1. The results on these demographic variables are not reported. Models 1 to 4 are logit analyses using different measures of unemployment. Model 1 performs the regression of food insecurity v. the dummy indicator of unemployment (whether household heads experienced unemployment or not during the observation period); model 2 does the same v. the number of episodes of unemployment; model 3 does the same v. the total duration of all episodes of unemployment (number of weeks); model 4 uses both the episodes and the duration of unemployment as predictors.
