RESUMO Uniformes da área médica datam desde os tempos medievais. Uniformes de enfermeiras eram baseados em roupas de freiras, enquanto o de médicos eram caracterizados pelas “vestimentas da praga” e fraques pretos de meados do século 15 até o início do século 19. No final do século 19, os uniformes começaram a mudar. A vestimenta de enfermeiras perderam suas similaridades com vestes religiosas. Médicos começaram a usar roupas brancas. Com o aumento da ênfase em higiene e no sanitarismo, começa a evoluir a ideia do uso de equipamento de proteção individual (EPI), com William Stewart Halsted utilizando luvas de borracha pela primeira vez em 1889. Nas décadas de 1960 e 1970 começa a se tornar mais usual a adesão ao pijama cirúrgico verdes e azul como roupa hospitalar, devido ao contraste com o ambiente branco já presente. Na contemporaneidade, algumas especialidades deixaram de usar uniformes específicos, enquanto outras ainda a usam. Ao mesmo tempo, EPIs tornaram-se mais e mais importantes, até, hoje em dia, surgir as “vestimentas da praga” atualizadas para o combate da epidemia do COVID-19.

ABSTRACT Medical Uniforms date back from medieval times. Nursing uniforms were based on nuns clothes whereas doctors used the famous “plague costumes” and black “frock” coats from about 15th to early 19th century. In latter half 19th century medical uniforms started to change. Nursing uniforms gradually lost their similarities to religious outfits. Doctors started to use white clothing. With great emphasis on hygiene and sanitation, the idea of personal protective equipment (PPE) started to evolve with William Stewart Halsted introducing the use of rubber gloves in 1889. In the 1960s-1970s it became more usual to wear green and blue `scrubs in order to look for a greater contrast in clothing with the all-white hospital environment. In contemporary times, some specialties even stopped using specific uniforms, while others still use them. At the same time, PPE became more and more important, up to nowadays “plague costume” in the combat of the COVID-19 epidemics.

ABSTRACT INTRODUCTION The prevalence of overweight in young people in Argentina between 18 and 24 years is estimated at 33%. Considering that the university environment is a strategic place for health interventions in this age group, the objective of the study was to describe the physical and economic characteristics of food selling points at Argentine universities. METHODS A cross-sectional multicenter descriptive study was conducted. Food selling points of 174 university buildings were surveyed through non-participant observation and registration in structured forms, considering following variables: offer of free safe water; characteristics of the offer of food and beverages at points of sale; informal sale; presence of advertising and presence of health promotion messages. RESULTS In 36% of the buildings there was no offer of free safe water. A total of 301 points of sale of food and/or beverages were observed, with 93% offering sugary sodas, 88% bottled water (with or without gas) and 86% sugary flavored waters and light sodas. A combined analysis showed that the presence of promoted products was not a determining factor for the reduction of the offer of non-recommended or allowed products. CONCLUSIONS It is important to advance in the regulation of food environments at universities, since the results are alarming. There is also a need to deepen the standards for the certification of healthy universities.

RESUMEN INTRODUCCIÓN Se estima que en Argentina hay un 33% de personas de 18 a 24 años con exceso de peso. Teniendo en cuenta que el ámbito universitario constituye un espacio estratégico para el abordaje de este grupo etario, el objetivo del estudio fue describir la dimensión física y económica de los entornos alimentarios de las universidades argentinas. MÉTODOS Se realizó un estudio descriptivo de corte transversal y multicéntrico. Se relevaron 174 edificios universitarios mediante observación no participante y registro en formularios estructurados, considerando las siguientes variables: oferta de agua segura sin costo; oferta de alimentos y bebidas en puntos de expendio; venta ambulante; presencia de publicidad y de mensajes de promoción de salud. RESULTADOS En el 36% de los edificios no se registró oferta de agua segura gratuita. Se observaron 301 puntos de expendio de alimentos y/o bebidas. En un 93% se ofrecían gaseosas azucaradas, en un 88% agua envasada (con o sin gas) y en un 86% aguas saborizadas azucaradas y gaseosas light. Un análisis cruzado evidenció que la venta de productos promovidos no era un factor determinante para la reducción de la oferta de productos no recomendados o permitidos. CONCLUSIONES: Es importante avanzar en la regulación de los entornos alimentarios en el ámbito universitario, ya que los valores obtenidos resultan alarmantes. Se observa también la necesidad de profundizar en los estándares para la certificación de universidades saludables.

Abstract: Objective: To describe the population that reports to have visited tobacco points of sale (POS) in Argentina and their perception of tobacco advertising. Materials and methods: We used data from the 2013 National Risk Factor Survey. Results: We included 31 167 respondents (96% of the total) who attended a store that sells cigarettes in the previous 30 days. Overall, 54.1% (67.3% of current smokers, 55.1% of former smokers and 49% of non smokers) referred having seen tobacco advertising at the POS. Males (OR=1.2) and current smokers (OR=1.9 vs. non smokers) were more likely to report having seen tobacco advertising at the POS. Those who were exposed to second hand smoke in bars and restaurants (OR=1.2) were also more likely to have seen advertising. We found that younger people (age 18 - 24) were more likely to be exposed (OR=2.8 vs older than 65). Among smokers, those who referred to have seen the advertising were more likely to have tried to quit smoking during the previous year. Conclusions: It is important to regulate advertising at the POS to limit exposure, particularly among young people.

Resumen: Objetivo: Describir las características de la población que refiere haber acudido a los puntos de venta (PV) de tabaco en relación con la percepción de la publicidad en Argentina. Material y métodos: Se analizaron datos de la Encuesta Nacional de Factores de Riesgo de 2013. Resultados: Se incluyeron 31 167 encuestados que acudieron a comercios donde venden cigarrillos en los últimos 30 días. De éstos, 54.1% dijo haber visto publicidad de cigarrillos. Los varones (RM=1.2) y los fumadores actuales (RM=1.9 vs. no fumador) tuvieron más posibilidad de percibirla. Aquéllos que refirieron estar expuestos al humo de tabaco en bares y restaurantes (RM= 1.2) tuvieron más posibilidad de ver publicidad de tabaco en los puntos de venta. Hubo un gradiente en relación con la edad: los jóvenes de 18 a 24 fueron más susceptibles a referir exposición (RM=2.8 vs >65 años). Entre los fumadores, aquéllos que percibieron publicidad refirieron con mayor frecuencia haber intentado dejar de fumar en el último año. Conclusiones: Es importante que la regulación de la publicidad en los PV sea más estricta para limitar la exposición a la publicidad, particularmente en los jóvenes.
