ABSTRACT
This study explores how the Household Dietary Diversity Score (HDDS) and spatial visualization can inform food governance in Chile, focusing on socio-demographic and geographical determinants affecting food consumption patterns. A national household database (n = 4047), including households from 2019 (n = 3967; 98.02%) and 2020 (n = 80; 1.98%), provided by the "Family Support Program of Food Self-Sufficiency" (FSPFS) of the Ministry of Social Development and Family, was analyzed. The findings revealed that Chilean vulnerable households were led mostly by women (86.6%), with an age average of 55.9 ± 15.6 years old, versus 68.9 ± 12.9 years in the case of men. The intake frequency analysis showed that dairy, fruits, and vegetables were below the recommended values in at least half of the households, and that fats and sugars were above recommended levels. Regarding the HDDS (0-189), the national average was 91.4 ± 20.6 and was significantly influenced by the number of minors in the households, water access, food access issues, and residing in the Zona Sur. Finally, the spatial visualization showed that the Zona Central had higher consumption of fruits and vegetables, while the extreme zones Norte Grande and Zona Austral showed higher intakes of fats and sugars. These findings emphasize the importance of leveraging data insights like the HDDS and spatial visualization to enhance food security and inform food governance strategies.

A visualização espacial consiste em manipular, realizar rotações e inverter as imagens dos objetos. Essa é a habilidade cognitiva mais importante das aptidões espaciais e considerada como preditiva do desempenho acadêmico. Assim sendo, o presente estudo avaliou o desempenho em habilidades espaciais e sua relação com matemática. O Teste Informatizado de Visualização Espacial-TVZ2006A foi aplicado coletivamente em 255 estudantes, sendo 64,71 por cento destes do sexo masculino. A idade variou de 14 a 19 anos e 92 deles frequentavam Ensino Médio Regular e 163 o Profissionalizante. O desempenho escolar foi avaliado pela média anual na disciplina de matemática. Os escores variaram de 0 a 19 pontos no TVZ2006A e as médias variaram de 1,5 a 10,0. A correlação entre as médias e o TVZ2006A foi significativa, a qual atribui evidência de validade de critério para o TVZ2006A.(AU)
The spatial visualization is defined as the ability to manipulate, rotate and realize objects images inversions. This is the most important cognitive ability of the spatial aptitude and it can be considered as a predictive academic achievement. Consider this, the present study aimed to evaluate the spatial ability achievement and its relationship with mathematic score. The computerized test of Spatial Visualization (TVZ2006A) had a collective administration in 255 students, which 64,71 percent were male ones. The age variability was from 14 to 19 years old and 92 of the students were in high school and 163 of them were in the professional education. The achievement was assessed by the final Mathematic grade. The average scores were from 0 to 19 points in the TVZ2006A and the Mathematic average was from1, 5 to 10,0. The correlation between Mathematic average and TVZ2006A score was statistically significant, which is one of the criteria validity evidence to the TVZ2006A.(AU)

A visualização espacial é definida como a capacidade para gerar uma imagem mental, avaliar as transformações e armazenar as modificações produzidas. Pesquisas revelam que a visualização espacial, enquanto fator da habilidade espacial está diretamente relacionada com o bom desempenho escolar, principalmente, em Matemática, Física e Geografia, as quais exigem raciocínio para solucionar problemas. Assim, o objetivo do presente estudo foi identificar as correlações entre o desempenho de estudantes nas disciplinas de matemática, física e geografia com as habilidades de visualização e raciocínio espacial, avaliadas por meio de dois testes psicológicos. Participaram 116 estudantes do Ensino Médio, sendo 58,62% do gênero feminino com as idades variaram entre 14 e 18 anos (M=16,09; DP=0,98). Constatou-se correlação positiva estatisticamente significativa entre a visualização espacial e as disciplinas de matemática e geografia, entre a habilidade de visualização espacial e raciocínio espacial, e entre raciocínio espacial e matemática, física e geografia.(AU)
