Fatores associados à qualidade da dieta de adultos, residentes na Região Metropolitana de São Paulo, Brasil, 2002

Objetivou-se avaliar os fatores demográficos, sócio-econômicos e de estilo de vida associados à qualidade da dieta de adultos residentes na Região Metropolitana de São Paulo, Brasil. Estudo transversal, por meio de inquérito domiciliar, de base populacional, foi realizado no Distrito do Butantã e nos municípios de Itapecerica da Serra, Embu e Taboão da Serra. Utilizaram-se dados de um questionário e um recordatório de 24 horas de 1.840 adultos de 20 anos ou mais, de ambos os sexos, incluídos em um inquérito de saúde (ISA-SP). A qualidade da dieta foi avaliada através do índice de qualidade da dieta (IQD) adaptado para a realidade local. Utilizou-se análise de regressão linear para avaliar a associação entre o IQD e as demais variáveis. A maioria da população (75%) apresentou dieta que necessita de melhora. Observaram-se médias baixas para os componentes: frutas, verduras e legumes, leite e derivados. Número de bens de consumo duráveis, escolaridade do chefe da família e ter 60 anos ou mais se associaram ao IQD em homens. Para as mulheres, a faixa etária se associou ao IQD. Em ambos os modelos, o consumo de calorias se manteve como variável de ajuste

The right to the screen: from media education to educommunication in Brazil

Nowadays in Brazil, some social organizations, governments and mass media are discussing the need to establish an oversight committee to guarantee the quality of television programmes, as well as the need to set a system to determine what kind of pro, gram is appropriate for every television time slot. Across Brazil, a representative body of children and young people have come to the conclusion that the right to receive quality television programmes is not enough. The children of the new generations think they have the right to access new technologies and the production of their own messages, in accordance with their own creativity, interests and lifestyle projects within society.

Images of a `good nurse` presented by teaching staff

Nursing is at the same time a vocation, a profession and a job. By nature, nursing is a moral endeavor, and being a `good nurse` is an issue and an aspiration for professionals. The aim of our qualitative research project carried out with 18 nurse teachers at a university nursing school in Brazil was to identify the ethical image of nursing. In semistructured interviews the participants were asked to choose one of several pictures, to justify their choice and explain what they meant by an ethical nurse. Five different perspectives were revealed: good nurses fulfill their duties correctly; they are proactive patient advocates; they are prepared and available to welcome others as persons; they are talented, competent, and carry out professional duties excellently; and they combine authority with power sharing in patient care. The results point to a transition phase from a historical introjection of religious values of obedience and service to a new sense of a secular, proactive, scientific and professional identity.

Maternal decision on obtaining prenatal care: a study in Brazil

Objective: to address the social aspects of pregnancy and the views of pregnant women regarding prenatal assistance in Brazil. Design: this qualitative study was focused on describing the Social Representations of prenatal care held by pregnant women. The discourse of the collective subject (DCS) framework was used to analyse the data collected, within the theoretical background of social representations, as proposed and developed by Serge Moscovici. Participants and setting: 21 pregnant women who were users of the publicly funded Brazilian unified health-care system and resided in the area served by its family health programme in a low- to middle-income neighbourhood on the outskirts of Campo Grande, the capital of the state of Mato Grosso do Sul, in southwestern Brazil. Data were collected by conducting in-depth, face-to-face interviews from January to October 2006. Findings: all participants were married. Formal education of the participants was less than five years in four cases, between five and eight years in six cases, and greater than 11 years in 10 cases. Nine participants had informal jobs and earned up to US$ 200 per month, four paricipants had administrative jobs and earned over US$ 500 per month, and eight participants did not work. No specific racial/ethnic background predominated. Lack of adherence to prenatal care allowed for the identification of two DCS themes: `organisation of prenatal care services` and `lifestyle features`. Key conclusions: the respondents were found to have negative feelings about pregnancy which manifest as many fears, including the fear of harming their children`s health, of being punished during labour, and of being reprimanded by health-care professionals for overlooking their prenatal care, in addition to the insecurity felt towards the infant and self. Implications for practice: the findings reveal that communication between pregnant women and healthcare professionals has been ineffective and that prenatal care has not been effective for the group interviewed-features that are likely to be found among other low- to middle-income groups living elsewhere in Brazil.

Women's health Australia: Recruitment for a national longitudinal cohort study

The Women's Health Australia (WHA) project is a longitudinal study of several cohorts of Australian women, which aims to examine the relationships between biological, psychological, social and lifestyle factors and women's physical health, emotional well-being, and their use of and satisfaction with health care. Using the Medicare database as a sampling frame (with oversampling of women from rural and remote areas), 106,000 women in the three age groups 18-23, 45-50 and 70-75 were sent an invitation to participate and a 24-page self-complete questionnaire. Reminder letters, a nation-wide publicity campaign, information brochures, a freecall number for inquiries, and the option of completing the questionnaire by telephone in English or in the respondent's own language, were used to encourage participation. Statutory regulations precluded telephone follow-up of non-respondents. Response rates were 41% (N = 14,792), 54% (N = 14,200) and 36% (N = 12,614) for the three age groups. Comparison with Australian census data indicated that the samples are reasonably representative of Australian women in these age groups, except fur a somewhat higher representation of women who are married or in a defacto relationship, and of women with post-school education. The most common reason for non-participation was lack of interest or time. Personal circumstances, objections to the questionnaire or specific items in it, and concerns about confidentiality were the other main reasons. Recruitment of three representative age-group cohorts of women, and the maintenance of these cohorts over a number of years, will provide a valuable opportunity to examine associations over time between aspects of women's lives and their physical and emotional health and well-being.

Transmission of ocular media in labrid fishes

Wrasses (Labridae) are the second largest family of fishes on the: Great Barrier Reef (after the Gobiidae) and, in terms of morphology and lifestyle, one of the most diverse. They occupy all zones of the reef from the very shadow reef flats to deep slopes, feeding on a variety of fauna. Many wrasses also have elaborately patterned bodies and reflect a range of colours from ultraviolet (UV) to far red. As a first step to investigating the visual system of these fishes we measured the transmission properties of the ocular media of 36 species from the Great Barrier Reef, Australia, and Hawaii, California and the Florida Keys, USA. Transmission measurements were made of whole eyes with a window cut into the back, and also of isolated lenses and corneas. Based on the transmission properties of the corneas the species could be split into two distinct groups within which the exact wavelength of the cut-off was variable. One group had visibly yellow corneas, while the corneas of the other group appeared clear to human observers. Five species had ocular media that transmitted wavelengths below 400 nm, making a perception of UV wavelengths for those species possible. Possible functional roles for the different filler types are discussed.

Screening for abdominal aortic aneurysm: lessons from a population-based study

Objectives: To test the acceptability of screening and to identify modifiable risk factors for abdominal aortic aneurysm (AAA) in men. Design: A trial of ultrasound screening for AAA in a population-based random sample of men aged 65-83 years, and a cross-sectional case-control comparison of men in the same sample. Participants: 12203 men who had an ultrasound examination of their abdominal aorta, and completed a questionnaire covering demographic, behavioural and medical factors. Main outcome measures: Prevalence of AAA, and independent associations of AAA with demographic, medical and lifestyle factors. Results: Invitations to screening produced a corrected response of 70.5%. The prevalence of AAAs (> 30 mm) rose from 4.8% in men aged 65-69 years to 10.8% in those aged 80-83 years. The overall prevalence of large (> 50 mm) aneurysms was 0.69%. In a multivariate logistic model Mediterranean-born men had a 40% lower risk of AAA (> 30 mm) compared with men born in Australia (odds ratio [OR], 0.6; 95% CI, 0.4-0.8), while ex-smokers had a significantly increased risk of AAA (OR, 2.3; 95% CI, 1.9-2.8), and current smokers had even higher risks. AAA was significantly associated with established coronary and peripheral arterial disease and a waist:hip ratio greater than 0.9; men who regularly undertook vigorous exercise had a lower risk (OR, 0.8; 95% CI, 0.7-1.0). Conclusion: Ultrasound screening for AAA is acceptable to men in the likely target population. AAA shares some but not all of the risk factors for occlusive vascular disease, but the scope for primary prevention of AAA in later life is limited.

Impacts of Animal Traffic on the Brazilian Amazon Parrots (Amazona species) Collection of the Quinzinho de Barros Municipal Zoological Park, Brazil, 1986-2007

Eleven species of Amazon parrots (genus Amazona) are known to occur in Brazil, and nest poaching and illegal traffic pose serious conservation threats to these species. When the illegal owners realize these animals are incompatible with their expectations and lifestyle, or when the police arrests traders and owners, these trafficked animals are often considered unfit for release and sent to local zoos and captive breeders. A retrospective survey of animal and necropsy records from 1986 to 2007 was used to evaluate the impacts of animal traffic on the population composition and mortality patterns of Amazon parrots at the Quinzinho de Barros Municipal Zoological Park, Sorocaba, Brazil. Data were obtained for 374 Amazon parrots of ten Brazilian species, and there was evidence that the studied population could be split into two major groups: a majority belonging to the Amazona aestiva species and a minority belonging to the remaining species. In comparison, the animals of the first group were more frequently admitted from traffic-related origins (98 vs. 75%), had a shorter lifespan (median 301 days vs. 848 days) and a higher mortality within the first year postadmission (54 vs. 37%), were less likely to receive expensive treatments, and were more frequently housed off-exhibit. On an average, parrots were found to have a short postadmission lifespan (median 356 days), with 92.5% of the birds dying within their first five years in captivity. The paper discusses the difficult dilemmas these incoming traffic-related animals pose to zoo management and official anti-traffic policies. Zoo Biol 29:600-614, 2010. (C) 2010 Wiley-Liss, Inc.

Relating body mass index to figural stimuli: population-based normative data for Caucasians

OBJECTIVE: To establish body mass index (BMI) norms for standard figural stimuli using a large Caucasian population-based sample. In addition, we sought to determine the effectiveness of the figural stimuli to identify individuals as obese or thin. DESIGN: All Caucasian twins born in Virginia between 1915 and 1971 were identified by public birth record. In addition, 3347 individual twins responded to a letter published in the newsletter of the American Association of Retired Persons (AARP). All adult twins (aged 18 and over) from both of these sources and their family members were mailed a 16 page 'Health and Lifestyle' questionnaire. SUBJECTS: BMI and silhouette data were available on 16 728 females and 11 366 males ranging in age from 18- 100. MEASUREMENTS: Self-report information on height-weight, current body size, desired body size and a discrepancy score using standard figural stimuli. RESULTS: Gender- and age-specific norms are presented linking BMI to each of the figural stimuli. Additional norms for desired body size and discrepancy scores are also presented. Receiver operating curves (ROC) indicate that the figural stimuli are effective in classifying individuals as obese or thin. CONCLUSIONS: With the establishment of these norms, the silhouettes used in standard body image assessment can now be linked to BMI. Differences were observed between women and men in terms of desired body size and discrepancy scores, with women preferring smaller sizes. The figural stimuli are a robust technique for classifying individuals as obese or thin.

Estado nutricional e estilo de vida em vegetarianos e onívoros, Grande Vitória-ES

Objetivo: Descrever e analisar o estado nutricional e aspectos do estilo de vida de vegetarianos e onívoros residentes na Grande Vitória/ES, na faixa etária de 35 a 64 anos de idade. Material E Métodos: Trata-se de estudo observacional híbrido de casos prevalentes com avaliação retrospectiva da exposição. Os grupos de expostos (134) e não expostos à dieta onívora típica ocidental (67) foram determinados no início da investigação. Foram coletados dados antropométricos, bioquímicos, de atividade física e alimentação através de questionário e 3 recordatórios de 24 horas e diagnosticados sobrepeso, Razão Cintura Quadril (RCQ) inadequada e hipercolesterolemia. Colesterol total e frações, triglicerídeos, ácido úrico, sódio e potássio urinários foram comparados entre os grupos, através do teste t de Student. Foi usado o teste qui-quadrado para comparar proporções, com =0,05. Resultados: Foram encontradas diferenças significativas em relação à ocupação. Duração da atividade física e tempo assistindo televisão e/ou utilizando computador foram maiores entre os onívoros. Os vegetarianos relataram práticas alimentares mais saudáveis e menor consumo de lipídios, proteínas e sódio. Os onívoros apresentaram maior risco de sobrepeso, RCQ inadequada e hipercolesterolemia (valores de P<0,0001). HDL-colesterol não foi diferente nos grupos. Conclusão: Os vegetarianos apresentaram perfil nutricional mais adequado e menor risco para os agravos crônicos estudados, apesar de pequena diferença no padrão de atividade física regular entre os grupos estudados.

Avaliação do desempenho docente : objectivos e controvérsias

Actualmente, no campo específico da educação, a avaliação do desempenho tem vindo a assumir uma importância crescente e uma maior atenção dos investigadores pelos contextos escolares e pela relação directa entre a qualidade das abordagens de ensino e os níveis de desempenho dos alunos. No contexto do sistema educativo português, a preocupação com a eficácia passa a considerar a avaliação dos professores como uma prioridade, trazendo à discussão a profissionalidade docente e a sua avaliação. Assim, este estudo tem como objectivo a análise dos elementos potenciadores e condicionadores do actual modelo proposto pelo Decreto Regulamentar 2/2008 de 10 de Janeiro, bem como a sistematização de elementos complementares e /ou alternativos ao modelo vigente, a partir do que perspectivam os professores de uma escola secundária. Para a sua realização utilizou-se uma abordagem qualitativa suportada na grounded theory - estudo de caso. As técnicas de colheita de dados foram as entrevistas a nove docentes participantes e a análise de documentos relacionados com a política educativa da escola. O estudo permitiu concluir que o modelo apresenta dimensões controversas e que estas condicionam os objectivos intrínsecos do mesmo, sendo que a prevalência de questões burocráticas dificulta a sua implementação. Em consequência foram apresentadas algumas recomendações.
