Background: The International Network for Food and Obesity / Non-communicable Diseases (NCDs) Research, Monitoring and Action Support (INFORMAS) developed the Protocol to evaluate Food Availability in Supermarkets.
Objective: To describe the adaptation process of the protocol for its use in the City of Buenos Aires (BA) and to evaluate inter-observer variability when applying it in supermarkets in the city.
Methodology: The main indicator of the protocol is the relative availability of healthy (AS) vs. unhealthy (ANS) foods, calculated as the ratio between the length (m) of shelves assigned to AS and ANS (length AS/ANS). The selection of foods to be included in the indicator was adapted for its use in BA. To explore the performance of the indicator, a reference frame was built, measuring shelf length for all the foods and beverages offered in 5 supermarkets, which were classified as AS and ANS according to the Argentine dietary guidelines. The indicator was compared with the relative availability calculated from the reference. To evaluate inter-observer reliability, two observers carried out measurements in three supermarkets and the intra-class correlation coefficient (ICC) was calculated.
Results: According to the reference, shelf length AS/ANS varied between 0.16 and 0.61, with a mean of 0.34 (SD 0.18). The adapted indicator produced similar results with a mean difference of -0.05 (SD 0.04). The ICC between the measurements of both observers was 0.92 (95% CI 0.86-0.98).
Conclusion: The protocol was adapted to be applied in BA, with modifications in the foods to be evaluated and adequate inter-observer reliability. |

Introducción: La Red Internacional para la Investigación, Monitoreo y Apoyo a la Acción para la Alimentación, Obesidad y Enfermedades No Transmisibles (INFORMAS por su sigla en inglés) ha desarrollado el Protocolo para evaluar la Disponibilidad de Alimentos en Supermercados. Objetivos: Describir el proceso de adaptación del protocolo para utilizarlo en la Ciudad de Buenos Aires (BA) y evaluar la variabilidad inter-observador al aplicarlo en supermercados de la ciudad. Metodología: El principal indicador del protocolo es la disponibilidad relativa de alimentos saludables (AS) vs. no saludables (ANS), calculado como el cociente entre la longitud (m) de estantes asignados a AS y ANS (longitudAS/ANS). Se adaptó la selección de alimentos a incluir en el indicador para utilizarlo en BA. Para explorar el funcionamiento del indicador se construyó una referencia, midiendo todos los alimentos y bebidas ofrecidos en 5 supermercados, que se clasificaron en AS y ANS según las guías alimentarias argentinas. El indicador se comparó con la disponibilidad relativa calculada a partir de la referencia. Para evaluar la confiabilidad inter-observador dos observadores realizaron mediciones en tres supermercados y se calculó el coeficiente de correlación intra-clase (CCI). Resultados: Según la referencia, el cociente longitudAS/ANS varió entre 0,16 y 0,61, con una media de 0,34 (DE 0,18). El indicador adaptado produjo resultados similares con una diferencia media de -0,05 (DE 0,04). El CCI entre la mediciones de ambos observadores resultó 0,92 (IC95% 0,86-0,98). Conclusión: Se adaptó el protocolo para aplicarlo en BA, con modificaciones en los alimentos a evaluar y una adecuada confiabilidad inter-observador.

Objetivos: Descrever o processo de adaptação do protocolo para uso na Cidade de Buenos Aires (BA) e avaliar a variabilidade interobservador ao aplicá-lo em supermercados da cidade. Metodologia: O principal indicador do protocolo é a disponibilidade relativa de alimentos saudáveis (SA) vs. alimentos não saudáveis (ANS), calculado como o quociente entre o comprimento (m) das prateleiras atribuídas a AS e ANS (comprimento AS/ANS). A seleção dos alimentos a serem incluídos no indicador foi adaptada para uso no BA. Para explorar o funcionamento do indicador, foi construída uma referência, medindo todos os alimentos e bebidas oferecidos em 5 supermercados, que foram classificados como AS e ANS de acordo com as diretrizes dietéticas argentinas. O indicador foi comparado com a disponibilidade relativa calculada a partir da referência. Para avaliar a confiabilidade interobservador, dois observadores realizaram medições em três supermercados e foi calculado o coeficiente de correlação intraclasse (ICC). Resultados: De acordo com a referência, a relação longitude AS/ANS variou entre 0,16 e 0,61, com média de 0,34 (DP 0,18). O indicador adaptado produziu resultados semelhantes com uma diferença média de -0,05 (DP 0,04). O ICC entre as medidas de ambos os observadores foi de 0,92 (IC 95% 0,86-0,98). Conclusão: O protocolo foi adaptado para aplicação na BA, com modificações nos alimentos a serem avaliados e adequada confiabilidade interobservador. Universidad Nacional Cba.
