Impacto das campanhas publicitárias contra o tabagismo no comportamento do consumidor

Todos os anos, milhares de pessoas morrem vítimas de doenças causadas pelo consumo de produtos derivados do tabaco, este é considerado a principal causa de morte evitável. O tabaco também colabora com as seis das oito principais causas de mortes entre fumantes e não fumantes a nível mundial. Algumas medidas governamentais como as campanhas publicitárias antitabagistas, buscam alertar, conscientizar e mudar o pensamento e o interesse coletivo neste tipo de produto e consequentemente, diminuir a taxa de consumo. Avaliar se as crenças, pensamentos e atitudes dos brasileiros são influenciados por este tipo de publicidade e se o comportamento relacionado a não fumar ou deixar de fumar é uma consequência da persuasão das mensagens antitabagistas, ajudam a conhecer o real impacto destas campanhas e sua eficácia. Através dos métodos de investigação quantitativo e qualitativo e das análises extensiva e semiótica, a pesquisa inquiriu 272 indivíduos brasileiros à respeito das advertências sanitárias e das campanhas publicitárias antitabagistas, classificando-os como não fumantes, ex-fumantes e fumantes, identificando os elementos visuais e textuais que compõem a narrativa publicitária de 5 anúncios antitabagistas. Após a análise, a pesquisa concluiu que as campanhas publicitárias coordenadas pelo INCA – Instituto Nacional de Câncer, denominadas campanhas antitabagistas, são eficazes para alertar e conscientizar os indivíduos sobre os males causados pelo consumo do cigarro mas ineficazes para influenciar suas atitudes e comportamentos. Embora estas consigam persuadir à crença nas mensagens, fazendo com que os indivíduos as vejam como verdadeira, isto não é suficiente para que a intenção de deixar de fumar torne-se um ato prático. Todos os anúncios possuem o mesmo formato e a maioria utilizou o mesmo percurso visual, equilíbrio, enquadramento, luz, ângulo e função do personagem. Todos possuem textos com funções identificadora, ancoragem e apoio e a narrativa conota o cigarro como algo negativo, prejudicial, mortífero e destruidor.

Epidemiologic transition in northern Angola: discussion of cumulative results from CISA (Health Research Centre of Angola)

The 41 years of armed conflict (1961 to 2002) resulted in a poor development of the health care and education infrastructures, and forced the relocation of people to safer places, namely major urban cities like Luanda. This phase was characterized by typical demographic, nutritional and epidemiological profiles. With the end of this period Angola has been repeatedly ranked as one of the three fastest growing economies in the world, and along with the social stabilization and globalization, the country is facing the introduction of new medical technologies, improvement of health sys-tems and services, better access to them, and overall better quality of life. These changes could also be translating into socio-cultural, demographic and nutritional changes which in turn may leading to changes in the epidemiological profile of the country. Thus, the emergence of non-communicable diseases are likely to become an increasingly im-portant public health problem in Angola. Also, considering that several infectious diseases persist, our weakened health system will have to face a double burden. Thus, disease surveillance data on non-communicable diseases to determine their prevalence and impact, along with the major behavioural risk factors like consumption of tobacco, alcohol, diets and physical inactivity are urgently needed.

Ecological footprint as an indicator of sustainability at Lisbon School of Health Technology, Portugal

Higher education institutions, has an active role in the development of a sustainable future and for this reason, it is essential that they became environmentally sustainable institutions, applying methods such as the Ecological Footprint analysis. This study intent is to strengthen the potential of the ecological footprint as an indicator of the sustainability of students of Lisbon School of Health Technology, and identify the relationship between the ecological footprint and the different socio-demographic variables.

Carbon footprint of the academic community of Lisbon School of Health Technology, Portugal

According to the Intergovernmental Panel on Climate Change, the average temperature of the Earth's surface has risen about 1º C in the last 100 years and will increase, depending on the scenario emissions of Greenhouse Gases. The rising temperatures could trigger environmental effects like rising sea levels, floods, droughts, heat waves, hurricanes. With growing concerns about different environmental issues and the need to address climate change, institutions of higher education should create knowledge and integrate sustainability into teaching programs and research programs, as well as promoting environmental issues for society. The aim of this study is to determine the carbon footprint of the academic community of Lisbon School of Health Technology (ESTeSL) in 2013, identifying possible links between the Carbon Footprint and the different socio-demographic variables.

Formaldehyde: exposure and genotoxicity assessments and potential health effects

Worldwide formaldehyde is manipulated with diverse usage properties, since industrial purposes to health laboratory objectives, representing the economic importance of this chemical agent. Therefore, many people are exposed to formaldehyde environmentally and/or occupationally. Considering the latter, there was recommended occupational exposure limits based on threshold mechanisms, limit values and indoor guidelines. Formaldehyde is classified by the International Agency for Cancer Research (IARC) as carcinogenic to humans (group 1), since a wide range of epidemiological studies in occupational exposure settings have suggested possible links between the concentration and duration of exposure and elevated risks of nasopharyngeal cancer, and others cancers, and more recently, with leukemia. Although there are different classifications, such as U.S. EPA that classified formaldehyde as a B1 compound, probable human carcinogen under the conditions of unusually high or prolonged exposure, on basis of limited evidence in humans but with sufficient evidence in animals. Formaldehyde genotoxicity is well-known, being a direct-acting genotoxic compound positively associated for almost all genetic endpoints evaluated in bacteria, yeast, fungi, plants, insects, nematodes, and cultured mammalian cells. There are many human biomonitoring studies that associate formaldehyde occupational exposure to genomic instability, and consequently possible health effects. Besides the link with cancer, also other pathologies and symptoms are associated with formaldehyde exposure, namely respiratory disorders such as asthma, and allergic contact dermatitis. Nowadays, there are efforts to reduce formaldehyde exposure, namely indoor. Europe and United States developed more strict regulation regarding formaldehyde emissions from materials containing this agent. Despite the regulations and restrictions, formaldehyde still continues to be difficult to eliminate or substitute, being biomonitoring an important tool to control possible future health effects.

Environmental mycology in public health: fungi and mycotoxins risk assessment and management

Fungi are essential to the survival of our global ecology, but they might pose a significant threat to the health of occupants when they grow in our buildings. The exposure to fungi in homes is a significant risk factor for a number of respiratory symptoms. Well-known illnesses caused by fungi include allergy and hypersensitivity pneumonitis. Environmental monitoring for fungi and their disease agents are important aspects of exposure assessment, but few guidelines exist for interpreting their health impacts. This book answers the questions: How does one detect and measure the presence of indoor fungi? What is an acceptable level of indoor fungi? How do we relate this information to human health problems?

Environmental microbiology for public health: capturing international developments in the field

Environmental microbiology is an evolving science. This is in part driven by the development of new analytical techniques that are becoming more varied and powerful. Before they are applied, emerging techniques need to be critically evaluated by scientists, technical professionals, practitioners and students.

Selenium role in an human biomonitoring study applied to occupational health

Selenium functions as a co-factor for the reduction of antioxidant enzymes and is an important component of antioxidant enzymes. Dietary selenium significantly inhibits the induction of skin, liver, colon, and mammary tumours in experimental animals by a number of different carcinogens, as well as the induction of mammary tumours by viruses. Selenium shows a “U” shaped curve for functionality, whereby too little is as damaging as too much. At optimal levels, selenium may protect against the formation of DNA adducts, DNA or chromosome breakage, chromosome gain or loss, mitochondrial DNA, and telomere length and function. Aim of study: Investigate the relation between selenium and genotoxic effects in a human biomonitoring study applied to occupational health.
