Vitamin A deficiency in poor, urban, lactating women in Bangladesh: factors influencing vitamin A status

Aims: To investigate the prevalence of vitamin A deficiency among lactating women in a poor urban population of Bangladesh, and to examine the relationship between various factors and vitamin A status. Design: Cross-sectional study. Setting: Maternal and child health clinic in Dhaka City, Bangladesh. Subjects and methods: A total of 120 lactating women aged 17-37 years were randomly selected from women who attended a local maternal and child health clinic in Dhaka City for immunisation of their children. Various socio-economic, personal characteristics, dietary intakes of vitamin A and anthropometric data were collected. Serum retinol (vitamin A) concentration was determined as a measure of vitamin A status. Results: Of the subjects, 37% had low serum vitamin A levels (<30 μg dl(-1)), with 13.3% having sub-clinical vitamin A deficiency (<20 mug dl(-1)). Eighty-seven per cent had vitamin A intakes below the recommended dietary allowance. The lactating women who were either illiterate or received only informal education had significantly (P=0.002) lower serum vitamin A levels compared with those who received formal education. The women whose husbands received formal education had significantly (P=0.05) higher serum vitamin A levels than those whose husbands were either illiterate or received only informal education. The serum vitamin A levels of women in households with poor sanitation/latrine practice were significantly (P=0.03) lower than those of women in households with good sanitation/latrine practice. The women with one child had significantly (P=0.015) lower serum vitamin A levels than those with two or more children. Women with a lactation period of 6 months or more had significantly (P=0.034) lower serum vitamin A levels than women with a lactation period of less than 6 months. The women who consumed less than the median vitamin A intake (274.8 mug day(-1)) had significantly (P=0.01) lower serum vitamin A levels than those who consumed more than the median vitamin A intake. By multiple regression analysis, education level of the women, number of living children, duration of lactation and dietary intake of vitamin A were found to have significant independent relationships with serum vitamin A. The overall F-ratio (6.8) was highly significant (P=0.000), the adjusted R-2 was 0.16 (multiple R=0.44). Conclusion: A significant proportion of poor, urban, lactating women in Bangladesh have vitamin A deficiency. Among the various factors, education level of the women, number of living children, duration of lactation and dietary intake of vitamin A appear to be important in influencing the vitamin A status of these women.

Anaemia and vitamin A deficiency in poor urban pregnant women of Bangladesh

This cross-sectional study investigated the prevalence of anaemia and vitamin A deficiency (VAD) among pregnant women in a poor urban population of Bangladesh. It also examined the association of various socio-economic and dietary factors with anaemia and vitamin A status. A maternal and child health clinic in Dhaka city, Bangladesh was used to obtain the sample. Three hundred and eighty three pregnant women, aged 20-30 years, of 20-30 weeks gestation were randomly selected from women on their first presentation for antenatal care. Socio-economic, pregnancy related information, usual dietary pattern, and anthropometric data were collected. Blood haemoglobin and serum retinol (vitamin A) concentrations were determined. About 40% of the pregnant women were anaemic (haemoglobin <11.0 g/dl) and 45% had low serum vitamin A levels (<30 mug/dl); with 8.6% having sub-clinical VAD (serum retinol <20 μg/dl). The women with low serum vitamin A levels had 1.8 times greater risk of being anaemic than did the women with normal vitamin A status. Food frequency data revealed that a large proportion of these women did not consume egg (49%), milk (25%), meat (31%), liver (83%), large fish (32%), small fish (39%) and sweet pumpkin (52%) at all; while about 25% of the women reported consuming dark green leafy vegetables (DGLV) and 64% reported an intake of fruit at least four servings a week. The pregnant women who were either illiterate or received only informal education (up to grade ten) had significantly lower haemoglobin and serum vitamin A levels compared to those who completed at least a secondary school certificate. The women whose husbands were illiterate or received only informal education had significantly (P=0.01) lower serum vitamin A levels than those whose husbands had received at least a secondary school certificate. The women who came from families with a per-capita income below the poverty line had significantly lower haemoglobin and serum vitamin A levels compared to those who came from families with a per-capita income above the poverty line. The women who consumed three servings or less of DGLV and fruit per week had significantly lower haemoglobin and serum vitamin A levels than those who consumed four or more servings a week. The women who never consumed large fish had significantly lower haemoglobin compared to those who reported at least one serving a week. Furthermore, the women who never consumed sweet pumpkin had significantly lower serum vitamin A than the women who ate at least one serving a week. By multiple regression analysis, intake of meat, DGLV and fruit, and serum vitamin A levels were found to have a significant independent relationship with haemoglobin. The overall F-ratio (9.9) was highly significant (P=0.000), the adjusted R-square was 0.086 (multiple R=0.309). Multiple regression analysis for serum vitamin A also revealed a significant independent relationship with per capita income, haemoglobin levels, intakes of DGLV and sweet pumpkin. The overall F-ratio (10.2) was highly significant (P=0.000), the adjusted R-square was 0.10 (multiple R=0.312). In conclusion, anaemia and vitamin A deficiency were highly prevalent among poor urban pregnant women in Bangladesh. Various socio-economic and dietary factors may influence the anaemia and vitamin A status of these women. The present study emphasizes the need for a comprehensive intervention strategy, which include both nutritional and environmental factors, to improve the nutritional status of this population.

EDUCACÃO E ECONOMIA SOLIDARIA: UM ESTUDO DE VIVÊNCIA DE CIDADANIA

A proposta desta pesquisa pressupõe que cada um de nós, e especificamente cada educador da associação em estudo, desenvolva sua ação educativa conforme suas convicções profundas sobre o ser humano, o mundo e a sociedade. Com qual consciência isso é vivido, é uma dúvida. Pode ocorrer que o indivíduo não tenha essa percepção. Pode ocorrer também que a pessoa pense fazer algo coerente, mas, na realidade, está agindo até contra suas próprias convicções, sem, contudo, ter consciência disso. Esta análise situa-se na perspectiva da educação popular não-formal que é desenvolvida pela Associação de Promoção Humana e Resgate da Cidadania, conhecida como Centro de Formação Profissional Padre Leo Commissari . Trata-se de uma pesquisa de pesquisa de tipo qualitativo para investigar o perfil dos educadores, e identificar sua concepção de ser humano, de mundo, de sociedade e de educação. O quadro teórico é alicerçado na visão de ser humano e de educação, segundo Paulo Freire, e na visão e identidade do ser brasileiro, de acordo com Darcy Ribeiro. A metodologia usada para a investigação é a observação participante, por meio dos jogos psicodramaticos do Psicodrama, de Jocob Levy Moreno, especialmente a teoria da Matriz de Identidade e da Ação. Tal analise permitiu identificar que os educadores participantes apresentam uma visão de ser humano contraditório, retraído e incompleto, reprodutor de uma sociedade dividida em classes. A educação, identificada como uma pilastra de garantia da vida, impregnada pela conserva cultural, parece contradizer uma vontade política de transformação.

INCENTIVO À LEITURA: UMA REFLEXÃO A PARTIR DA ANÁLISE DE PROJETOS DO COLE

Este trabalho teve por objetivo analisar os Cadernos de Resumo dos três últimos COLEs (Congresso de Leitura) - anos 2001, 2003 e 2005 -, mapeando os projetos de incentivo à leitura, para conhecer o que se produz no País sobre essa temática. A partir desse conhecimento, volto ao Projeto Vô Di - Leitores de Luz, por mim idealizado, buscando analisar seus fundamentos teórico-metodológicos. Por meio da análise dos projetos apresentados nos COLEs, procurei mapear as atividades, os referenciais teóricos e os objetivos utilizados, evidenciando o que é produzido no Brasil e mesmo internacionalmente sobre leitura, a incidência dos projetos na educação formal e na educação não formal e a quantidade de projetos que são voltados às séries iniciais do ensino fundamental, ao ensino médio, aos cursos de graduação, aos cursos de especialização e às ONGs. Um dos resultados deste trabalho é a constatação de que houve uma grande mudança na incidência de projetos da educação formal para a educação não formal, sendo que a maioria dos projetos de incentivo à leitura são desenvolvidos, no COLE, pelas ONGs.

SEMEANDO A CIDADANIA: um estudo sobre a formação e a atuação de educadoras sociais em prol do letramento

Esta dissertação de Mestrado tem como objetivo desvelar a prática pedagógica de educadoras leigas atuantes na educação não-formal e a práxis educacional que elas desempenham em prol da alfabetização letrada. Ao abordarmos os três temas que regem este estudo educação não-formal, formação de educadoras leigas e alfabetização letrada versamos sobre os resultados obtidos em espaços de educação não-formais, estabelecendo um contraponto: até quando o não-formal pode ser considerado um espaço de educação aquém da escola? Foi realizada uma pesquisa empírica no Projeto Sementinha da cidade de Santo André/ SP, através da observação da práxis educativa de sete educadoras, de entrevistas, coma exsecretária de Educação que implantou o Projeto na cidade; com os Coordenadores Gerais do Projeto Sementinha; com quatro das sete educadoras e ainda, um levantamento bibliográfico sobre o surgimento do Projeto na cidade de Curvelo; MG. Até o momento, as análises realizadas apontaram para o desenvolvimento de práticas de letramento em diferentes momentos da atuação das educadoras e na formação cidadã e moral das crianças assistidas pelo Projeto na comunidade observada para a efetivação deste trabalho de pesquisa.(AU)

The relationship between classroom interactions and exclusionary discipline as a social practice: A critical microethnograhy

Exclusionary school discipline results in students being removed from classrooms as a consequence of their disruptive behavior and may lead to subsequent suspension and/or expulsion. Literature documents that nondominant students, particularly Black males, are disproportionately impacted by exclusionary discipline, to the point that researchers from a variety of critical perspectives consider exclusionary school discipline an oppressive educational practice and condition. Little or no research examines specific teacher-student social interactions within classrooms that influence teachers’ decisions to use or not use exclusionary discipline. Therefore, this study set forth the central research question: In relation to classroom interactions in alternative education settings, what accounts for teachers’ use or non-use of exclusionary discipline with students? A critical social practice theory of learning served as the framework for exploring this question, and a critical microethnographic methodology informed the data collection and analysis. ^ Criterion sampling was used to select four classrooms in the same alternative education school with two teachers who frequently and two who rarely used exclusionary discipline. Nine stages of data collection and reconstructive data analysis were conducted. Data collection involved video recorded classroom observations, digitally recorded interviews of teachers and students discussing selected video segments, and individual teacher interviews. Reconstructive data analysis procedures involved hermeneutic inferencing of possible underlying meanings, critical discourse analysis, interactive power analysis and role analysis, thematic analysis of the interactions in each classroom, and a final comparative analysis of the four classrooms. ^ Four predominant themes of social interaction (resistance, conformism, accommodation, and negotiation) emerged with terminology adapted from Giroux’s (2001) theory of resistance in education and Third Space theory (Gutiérrez, 2008). Four types of power (normative, coercive, interactively established contracts, and charm), based on Carspecken’s (1996) typology, were found in the interactions between teacher and students in varying degrees for different purposes. ^ This research contributes to the knowledge base on teacher-student classroom interactions, specifically in relation to exclusionary discipline. Understanding how the themes and varying power relations influence their decisions and actions may enable teachers to reduce use of exclusionary discipline and remain focused on positive teacher-student academic interactions. ^

A study of the relationship between educational placement and the achievement of urban low socioeconomic Hispanic middle school students with and without specific learning disabilities

Public schools traditionally have been held accountable for educating the majority of the nation’s school children, and through the years, these schools have been evaluated in a variety of ways. Currently, evaluation measures for accountability purposes consist solely of standardized test scores. In the past, only test scores of general education students were analyzed. Laws governing the education of students with disabilities, however, have extended accountability measures not only to include those students, but to report their scores in a disaggregated form (No Child Left Behind Act, 2001). The recent emphasis on accountability and compliance has resulted in the need for schools to carefully examine how programs, services, and policies impact student achievement (Bowers & Figgers, 2003). ^ Standard-based school reform and accountability systems have raised expectations about student learning outcomes for all students, including those with disabilities and minority students. Yet, overall, racial/ethnic minority students are performing well below their White non-Hispanic peers in most academic areas. Additionally, with respect to special education, there exists an enduring problem of disproportionate representation of racial/ethnic minority students (National Research Council, 2000). ^ This study examined classroom placement (inclusive versus non-inclusive) relative to academic performance of urban, low socioeconomic Hispanic students with and without disabilities in secondary content area classrooms. A mixed method research design was used to investigate this important issue using data from a local school district and results from field observations. The study compared performance levels of four middle school Hispanic student subgroups (students with disabilities in inclusive settings, students without disabilities in inclusive settings, students with disabilities in resource settings, and student without disabilities in general education settings) each in their respective placements for two consecutive years, exploring existing practices within authentic settings. ^ Significant differences were found in the relationship of educational placement and achievement between grade level and disability in the areas of math and reading. Additionally, clear and important differences were observed in student-teacher interactions. Recommendations for further researchers and stakeholders include soliciting responses from teams at the schools composed of general education and special education teachers, administrative personnel, and students as well as broadening the study across grade levels and exceptionalities. ^

Visitabilidade-vivenciabilidade em assentamentos informais : um estudo da acessibilidade de percursos urbanos no Conjunto Santa Terezinha em Fortaleza-CE

This research approaches the issue of accessibility in informal settlements, seeking for the challenges and limits defined by informal urban settings, about the application of accessibility parameters. Take the empirical universe as the Conjunto Santa Terezinha, located in Fortaleza- Ce. Initially, the study presents a reflection about the housing issue in Brazil and the informal settlementes in view of the Right to the City. In this sense, the main references are, the works of Suzanne Pasternak (2008), Nabil Bonduki (1998) and Erminia Maricato (1996-97), among others. Follows with the discussion of the concepts and classifications of this type of settlement, making a content analysis of legislation and regulations relating to accessibility and proposed the discussion of the accessible route as the right strategy for the city. In another step, the methodology of 'walking together' created by Dischinger (2000) was applied in a passage previously chosen, which the researcher follows the disabled person during the journey through city making records like photos and video. The comments and perceptions are compared to the spatial analysis of urban morphology, made from the method of Del Rio (1990) and Panerai (2006), and the parameters of NBR 9050. Knowledge of the area is enriched by the methodology of the production of space made by Henri Lefebvre in his book 'The production of space' (1974) with these categories: space conceived, perceived and lived. Another key reference of this author it s the book 'The Right to the City' (991), which allowed in-depth reflections on the social function of town. In conclusion, the study finds that to guarantee a minimum access conditions in informal sittlements it´s necessary to know the specifics of their morphology, their relations and urban practices in view of the visitability- experiencebility, describing it as complementary concepts

O associativismo cultural e o impacto na educação artística contemporânea em Portugal : o caso da Associação Cultural d'Orfeu

As associações culturais, como coletividades que emancipam o papel do cidadão na criação e produção de atividades culturais, contribuindo para a dinamização das sociedades, podem ser um veículo de desenvolvimento da educação artística, ao nível do ensino não formal e informal, tendo como ponto de partida o contributo da participação ativa dos cidadãos, que buscam a promoção e dinamização de atividades de teor cultural e artístico. Sendo assim, a seleção do Associativismo Cultural para o estudo da evolução da educação artística é um caminho para a compreensão da dinâmica das coletividades e o seu impacto no desenvolvimento cultural e artístico, a nível local, regional e nacional. Neste estudo, foi selecionada a Associação Cultural d´Orfeu, como estudo de caso, pela sua longevidade como associação e pelo seu destaque a nível cultural e artístico da zona centro do país. Ao nível da metodologia optámos por uma metodologia mista, tanto numa abordagem qualitativa, ao nível da análise de conteúdo, como quantitativa, na análise de dados. As técnicas de recolha de dados consistiram em entrevistas a dirigentes associativos e colaboradores (metodologia qualitativa), inquéritos a sócios, colaboradores e participantes de associações culturais (metodologia quantitativa), registos para diário de campo (acontecimentos, atividades e formação artística), análise de espólio documental da Associação Cultural d´Orfeu e registo audiovisual e fotográfico. Com este estudo, espera-se compreender as dinâmicas que estão inerentes ao associativismo cultural ao nível da educação/formação artística e que impactos apresentam no desenvolvimento cultural, social e artístico da sociedade. Além disso, queremos verificar que estratégias são utilizadas pelas associações culturais para a diversificação da oferta cultural e para o incentivo da cidadania ativa.

Trabalhar com a matemática em educação de infância

Este estudo tem como principal objetivo compreender e analisar o modo como crianças de creche e jardim-de-infância resolvem problemas matemáticos e o que pode constranger a resolução. Em particular, procurei analisar a atividade matemática que as crianças desenvolvem quando se confrontam com problemas matemáticos e os desafios com que se deparam. Do ponto de vista metodológico, o estudo enquadra-se numa abordagem qualitativa de investigação e num paradigma interpretativo. Além disso, trata-se de uma investigação-ação orientada pela questão “como otimizar a atividade de resolver problemas matemáticos em contextos de educação de infância?”. Neste âmbito, propus a quatro crianças de creche e a 21 de jardim-de-infância um conjunto de tarefas selecionadas para, potencialmente, terem, para si, algum grau de desafio. Os principais métodos de recolha de dados foram a observação participante, a análise documental e um inquérito por questionário realizado às educadoras cooperantes. O estudo ilustra que é possível envolver crianças de creche e de jardim-de-infância numa atividade de resolução de problemas matemáticos e que esta atividade é favorecida se o contexto dos problemas estiver próximo do que fazem no dia-a-dia da sala. Durante o processo de resolução das tarefas propostas, foram mobilizadas e trabalhadas diversas noções matemáticas. Na creche, todas as crianças evidenciaram possuir conhecimentos acerca da noção topológica “dentro de” e “fora de” e algumas foram bem-sucedidas no uso do processo de classificação, tendo em conta um critério. Neste âmbito, recorreram a representações ativas. No jardim-de-infância, todas as crianças conseguiram fazer a contagem sincronizada das letras do seu nome, de indicar a quantidade de letras, o que indicia o conhecimento da noção de cardinal, e de representar esta quantidade recorrendo tanto a numerais como a representações icónicas. Além disso, foram capazes de interpretar uma tabela de modo a construir um gráfico com barras e de elaborar um pictograma, o que revela possuírem conhecimentos ao nível da literacia estatística. Por último, algumas crianças foram bem-sucedidas na descoberta de estratégias de resolução de problemas que lhes permitiram inventariar exaustivamente todas as possibilidades de resolução e contar, organizadamente, estas possibilidades. No decurso desta atividade surgiram tentativas de generalização, embora nem sempre corretas, sobressaindo o recurso a representações ativas nomeadamente à dramatização de situações. Quanto aos desafios com que se depararam destacam-se, no caso da creche, o uso correto do processo de classificação. No caso do jardim-de-infância, as crianças demonstraram dificuldades em distinguir a legenda do pictograma dos dados, em resolver um problema em que estava em jogo o sentido combinatório da multiplicação e em encontrar estratégias de generalização. O estudo indicia, ainda, que é essencial que o educador proponha tarefas diversificadas e desafiantes que, partindo sempre da curiosidade e interesse das crianças, lhes permitam trabalhar com ideias matemáticas importantes e representar adequadamente o conhecimento com que lidam.
