A revista de estudos artísticos GAMA encontra, neste terceiro número, um caminho mais definido dentro do projeto global da comunicação de artistas sobre as obras de outros artistas. A Revista GAMA percorre tradições, registos, ações e intervenções artísticas, que assinalaram diversos momentos, com diferentes graus de difusão. Visa-se resgatar, recuperar a arte: é voltar a olhar, pelo escopo particular de um artista, a intervenção de um outro artista, com algum tempo de intervalo entre ambos. Este intervalo é um tempo de sedimentação, de filtragem, ou de recuperação de valores quase esquecidos. O tempo pode fornecer um ponto de vista privilegiado que permite novas interpretações, valorizações, interligações. Permite-se a reativação, o restauro: restauro não no sentido material, mas no sentido da reapresentação do conteúdo possibilitando reforçar um “museu imaginário,” livre de fronteiras e de hierarquias estabelecidas (Malraux). Os objetos de arte anteriores podem ter originado, ou vir a originar, novas obras, na sequência imprevisível dos discursos humanos mais significativos, reagrupando-se em termos de “ação” ou de “orientação,” de “imagem” ou de “palavra,” (Warburg) permitindo “restituir ao discurso o caráter de acontecimento” (Foucault). Entre a história e a memória, o arquivo e a deriva, a viagem e a identidade, a permanência e a resistência, a Revista GAMA vem assinalando um percurso de salvaguarda, de marcação de registos, de preservação de uma riqueza, ora material ora conceptual: a arte detém-se e debruça-se sobre as suas marcas, os seus projetos, os seus registos, as suas transições.

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants
Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks
Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We
estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from
1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories.
Methods We used data from 3663 population-based studies with 222 million participants that measured height and
weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate
trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children
and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the
individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference)
and obesity (BMI >2 SD above the median).
Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in
11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed
changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and
140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of
underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and
countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior
probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse
was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of
thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a
posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%)
with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and
obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for
both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such
as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged
children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls
in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and
42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents,
the increases in double burden were driven by increases in obesity, and decreases in double burden by declining
underweight or thinness.
Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an
increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy
nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of
underweight while curbing and reversing the increase in obesit
Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions
Estudo da sua adequação à criança e à sustentabilidade
Tese de Doutoramento em Design, com a especialização em Design de Produto apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Doutor.Esta investigação em design foca-se no bem-estar da criança e no mundo material envolvente. Tem como objectivos gerais, contribuir para uma melhor adequação do mobiliário à criança, potenciando um aumento do tempo útil de vida do produto e a sustentabilidade; melhorar o ambiente material infantil, tornando-o mais atractivo, saudável e sustentável. E como objectivos específicos, a procura de um conhecimento aprofundado acerca destas matérias, levando-o à prática num projeto de mobiliário doméstico infantil, mais concretamente, de uma cadeira alta para crianças dos 6 meses aos 7 anos, de modo a encontrar soluções mais confortáveis, mais estáveis aos níveis físico e psicológico e que contribuam para o desenvolvimento sustentável; a disponibilização da informação aos profissionais do sector, através de uma disseminação activa.
Nesta investigação, foi utilizada uma metodologia mista de base qualitativa, embora com alguns dados quantitativos. Numa 1ª fase, foi feita a contextualização histórico-teórica através de crítica literária e foram conduzidas entrevistas exploratórias a progenitores e crianças. Foi desenvolvido um estudo de casos, com 10 exemplos deste tipo de equipamentos, disponíveis no mercado actual. Foi também realizado um estudo com crianças do ensino pré-escolar, utilizando a cadeira Tripp Trapp® da marca Stokke®, Noruega.
Numa 2ª fase, empírica, foram conduzidas entrevistas a especialistas em design, produção, saúde e segurança infantil, bem como uma pesquisa acerca de materiais e tecnologias, recorrendo a contactos com a indústria.
Em paralelo, decorreu a 3ª fase, também empírica, essencialmente de projecto e prototipagem de uma cadeira infantil, que se pretende, seja viável em termos produtivos, resolvendo os problemas identificados e apresente baixo impacte ambiental. Ao longo da investigação foi levada a cabo uma disseminação activa, que resultou em vários contributos e em significativa produção científica publicada.
Os dois protótipos de cadeira alta infantil e um protótipo de almofada de conforto (para a produção do qual, foi estabelecida uma parceria com a empresa TintexTextiles), foram avaliados por um grupo de amostra de utilizadores directos e indirectos (crianças de várias idades e progenitores) e por um painel de especialistas, de modo a identificar falhas e/ou lacunas, levando a reformulações no projecto, regressando à hipótese ou argumento. Assim foi possível concluir, através de um projecto de design de produto optimizado para crianças, que é possível uma maior adaptação ao crescimento infantil, através de soluções que contribuam para a sustentabilidade. Esta investigação em design deixa também recomendações para futuras investigações.ABSTRACT: This research project is focused in the child's wellbeing and in the surrounding material world. Its overall objectives are, to contribute to a better adaptation of furniture to the child, leading to an extension of the average lifespan of products and to sustainability; create a better material environment for children, making it more attractive, healthy and sustainable. Its specific goals are, the search for a more profound understanding about this issues, taking it into practice in a project of children's home furniture, more specifically, of a high chair for children aged 6 months up to 7 years, in order to find solutions physically and psychologically more confortable and stable, which can contribute to sustainable development; the provision of information to professionals in this sector, through an active dissemination.
In this research it was used a mixed methodology mainly qualitative, although with some quantitative data. In its first phase, a theorical-historical contextualization was made through literary review and exploratory interviews to parents and children were conducted. A case study was developed, with 10 examples of high chair models, available in the current market. A study with pre-school children was also made, with the Tripp Trapp® chair, from Stokke® brand, Norway.
In a second and empirical phase, interviews to experts in design, production, health and child's safety were conducted, as well as a research about materials and technologies, using contacts with the industry.
Meanwhile, a third phase was being developed, also empirical, essentially consisting of project and prototyping of a children's high chair, which is intended to be feasible in a productive level, solving the identified problems and with low environmental impact. Throughout this investigation, an active dissemination was lead, resulting in several contributions for this research with significant essay writing and publication.
The two high chair prototypes and one comfort cushion (made in partnership with the textile company TintexTextiles), were evaluated by a sample group of direct and indirect users (children of several age groups and parents) and by an experts' panel, in order to identify problems and/or gaps, leading to reformulations of the project, also returning to the hypothesis or argument. It was possible to conclude, through an optimized design product for children, that it is possible to achieve a greater adaptation to the child's development, with solutions, which can contribute to sustainability. This research also leaves recommendations for future research.N/
Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial
Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author

Characterisation of microbial attack on archaeological bone
As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
