SUMMARY:

The conceptual complexity of Food and Nutrition Security (FNS) makes its assessment a challenge. Full indicators, like the food and nutritional components and their different dimensions: availability, access, stability, and biological use, are necessary. Despite this, the main instrument used in Brazil, the Brazilian Food Insecurity Scale (EBIA), includes only the dimension of access. A global indicator formulation is necessary to optimize the screening of individuals at risk of food insecurity (FI), especially in Nutritional Surveillance (NS). Thus, the aim was to assess the factors associated with food and nutritional insecurity (FNI). In addition, to develop a multidimensional screening instrument (Vigi-INSAN). The formulation of Vigi-INSAN used data from the Brazuca Natal Study, a cross-sectional study, conducted with 411 adults and older adults living at home. Home interviews were conducted using an electronic questionnaire to obtain demographic, socioeconomic, anthropometric data (weight, height, body perimeters), food consumption (items on the scale of adherence to Dietary Guidelines for the Brazilian Population), and FI measured by EBIA. The construction of Vigi-INSAN occurred in three stages: 1- Organization of the theoretical basis and selection of items, based on bivariate analysis; 2- Multiple Poisson regression to select the instrument's variables. Variables with p <0.20 were included in the model and those with p <0.05 remained in the final model; 3 - Analysis of adjustment assumptions with Omnibus test and deviance, and ROC curve to analyze the model's efficiency. The 5th and 75th percentiles were used as cutoff points. The factors associated with FI in the elderly population (n = 191) were also investigated. For this, the crude and adjusted prevalence ratios were analyzed using Poisson Regression. The prevalence of FI was 42.1% (37.4% - 46.9%). Women (47.5%), adults (48.2%) and people of non-white color / race (52.7%) had significantly higher FI. After multiple analysis, the presence of children under 18 at home (ajPR = 1.3; 1.0 - 1.6), main income (<R$ 998.00) (ajPR = 1.6; 1.2 - 2.0), the work situation (ajPR = 1.2; 1.0 - 1.5), the type of drinking water treatment (ajPR= 1.4; 1.2 - 1.7), the presence of chronic non-communicable diseases (ajPR = 1.3; 1.0 - 1.7), the absence of the habit of eating fruit for breakfast (ajPR = 2.1; 1.5 – 3.0), the habit of eating meals on the living room sofa or bed (ajPR = 1.3; 1.1 - 1.6) and skipping at least lunch or dinner (ajPR = 1.4; 1.1 - 1, 7) were selected to compose Vigi-INSAN, with an area under the ROC curve of 80%. The proposed scores were: <0.3 = Low; 0.3 to 1.9 points = Moderate; > 1.9 = High probability of FNI. In older people, income below R $ 998.00 (ajPR = 1.47; 1.01 - 2.14), not having a job or retirement (ajPR = 7.39; 1.30 - 2.49), do not eating fruit for breakfast ajPR = 7.39; 2.478– 19.66) and skipping at least lunch or dinner (ajPR = 1.75; 1.27 - 2.40) made up the adjusted model. It is concluded that Vigi-INSAN has potential for use in NS, based on multidimensional indicators, at the household and individual level.
