  1. Odds ratios and 95% confidence limits of risk factors for households’ food insecurity
  2. Multivariable-adjusted logistic regression analysis was used and independent variables included all the variables listed as demographic, economic (%proportion for expenditure), and food environment characteristics. A stepwise approach was applied to select the most explainable risk factors in the model (α = 0.15)
  3. a Reference group was subjects who responded “no” to the question
  4. b Reference group was subjects who purchased foods without difficulties in food purchasing due to food stores far from home
