      Measurement Scale to identify risk groups: evidence from a nationwide 
      representative sample.

AB  - OBJECTIVE: The Brazilian Household Food Insecurity Measurement Scale (EBIA) has 
      eight general/adult items applied in all households and six additional items 
      exclusively asked in households with children and/or adolescents (HHCA). 
      Continuing an investigation programme on the adequacy of model-based cut-off 
      points for EBIA, the present study aims to: (i) explore the capacity of properly 
      stratifying HHCA according to food insecurity (FI) severity level by applying 
      only the eight 'generic' items; and (ii) compare it against the fourteen-item 
      scale. DESIGN: Latent class factor analysis (LCFA) models were applied to the 
      answers to the eight general/adult items to identify latent groups corresponding 
      to FI levels and optimal group-separating cut-off points. Analyses involved a 
      thorough classification agreement evaluation and were performed at the national 
      level and by macro-regions. SETTING: Data derived from the cross-sectional 
      Brazilian National Household Sample Survey of 2013. PARTICIPANTS: A nationally 
      representative sample of 116 543 households. RESULTS: In all households and 
      investigated domains, LCFA detected four distinct household food (in)security 
      groups (food security and three levels of severity of FI) and the same set of 
      cut-off points (1/2, 4/5 and 6/7). Misclassification in the aggregate data was 
      0.66 % in adult-only households and 1.06 % in HHCA. Comparison of the scale 
      reduced to eight items with the 'original' fourteen-item scale demonstrated 
      consistency in the classification. In HHCA, the agreement between both 
      classifications was 96.2 %. CONCLUSIONS: Results indicate the eight 'generic' 
      items in HHCA can be reliably used when it is not possible to apply the 
      fourteen-item scale.
