    Este trabalho trata da temática mulher e reforma agrária, e tem como objetivo compreender o tipo de participação que as mulheres rurais têm apresentado nas lutas pela conquista da terra e melhores condições de vida. O estudo foi realizado no Curso de Especialização em Agricultura Familiar Camponesa e Educação do Campo sobre a metodologia da pesquisa-ação. O trabalho apresenta referenciais teóricos e dados referentes a pesquisa realizada em um assentamento rural do Ceará. Percebemos que a participação da mulher é presente e tem importante significado nos acontecimentos que representam a luta pela conquista da terra, bem como sua presença nas etapas de constituição e organização do assentamento. A questão é que as agricultoras apresentam uma profunda insatisfação em relação ao reconhecimento de suas ações, tanto por parte das instituições governamentais, como da sociedade de modo geral, e principalmente daqueles que estão mais próximos, como maridos, filhos e familiares em geral

    A água corresponde a um componente fundamental do bem-estar humano. Estudos sobre a relação deste recurso com a realidade rural tem sido muito explorados no ambiente acadêmico, porém com pouca expressividade para o bem-estar subjetivo das populações no tocante a água. Considerando esta problemática, o objetivo do artigo é identificar a produção científica internacional sobre bem-estar subjetivo relacionado a questão do acesso a água em comunidades rurais. O método utilizado se fundamenta na análise bibliométrica da produção científica indexada à base de dados Scopus, abrangendo o período entre 2008 – 2018. Além da construção de mapa de ocorrências de itens com uso do software VOSviewer. Os resultados revelam que: os estudos sobre o tema são recentes, sem evidências para o Brasil; é limitada a produção acadêmica na década atual; as Ciências Ambientais se destacam entre as áreas de publicação; há forte tendência em abordagens envolvendo os termos governo, água, pobreza, agricultura, ecossistema e qualidade de vida e fraca abordagem de questões importantes como governança, tecnologias alternativas e participação social

    http://dx.doi.org/10.5902/2318179610221As pesquisas relacionadas com multifuncionalidade e pluriatividade trazem como unidade de observação apenas as famílias que praticam agricultura familiar. Nesta pesquisa pretendeu-se ampliar estes olhares também para analisar as famílias que realizam a pesca artesanal, não só de forma isolada, mas combinada com a agricultura familiar e trabalhos não agrícolas. Este artigo traz como objetivos analisar a pesca artesanal desenvolvida na comunidade Apiques, Assentamento Maceió, Itapipoca-CE à luz da multifuncionalidade e identificar as atividades no âmbito da pluriatividade realizadas pelas famílias da comunidade pesquisada. Foi utilizada a metodologia Análise Diagnóstico de Sistemas Agrários (ADSA) e a técnica de pesquisa observação participante. Os resultados foram a construção da Tipologia dos Sistemas de Produção identificados, os Fluxogramas de Fertilidade e Produtos e os Calendários de atividades de dois tipos de sistemas de produção. Assim tem-se que a multifuncionalidade permite analisar a pesca artesanal sob aspectos que superam a lógica produtivista, enquanto modo de vida, por centralizar a família e suas relações com o espaço rural e a natureza, reconhecendo sua relevância para a sociedade através dos diversos serviços materiais e simbólicos prestados, além de evidenciar a importância de se ampliar as oportunidades de emprego no âmbito da pluriatividade

    Potencialidades e caracterização da produção agrícola familiar: Uma análise a partir dos quintais produtivos

    Get PDF
    Este estudo tem o objetivo de caracterizar as potencialidades da produção agrícola familiar decorrente dos quintais produtivos do Assentamento Vida Nova/Aragão, localizado no município de Miraíma, Ceará. Os quintais configuram-se como uma tecnologia social que permite a combinação de espécies alimentícias, florestais e medicinais, associadas com a criação de pequenos animais nos espaços adjacentes a residências. Os dados coletados foram obtidos a partir de entrevistas semiestruturadas com 19 famílias residentes no local. Observou-se a produção de frutíferas, hortaliças, plantas medicinais, leguminosas (feijão), gramíneas (milho) e a criação de aves, suínos e cabras. Os insumos empregados no controle de pragas e na adubação são provenientes do próprio assentamento, sendo representados pela utilização de defensivos alternativos e adubos orgânicos, respetivamente. Os resultados dessa produção destinam-se especialmente para o autoconsumo, distribuição para outras famílias dentro do assentamento e comercialização do excedente. Devido a fatores como o manejo ecológico utilizado, acesso a água e demais insumos, os quintais possibilitam o cultivo de uma diversidade de espécies que se encontram acessíveis durante o ano todo, além de garantir a renda por intermédio da comercialização do excesso produzido. &nbsp

    Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018 population-based measurement studies with 88.6 million participants

    © The Author(s) 2018. Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups

    Rising rural body-mass index is the main driver of the global obesity epidemic in adults

    Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.Peer reviewe

    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

    Mapping age- and sex-specific HIV prevalence in adults in sub-Saharan Africa, 2000-2018

    Get PDF
    BACKGROUND: Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for effective geographic and epidemiological targeting of prevention and treatment interventions. Age- and sex-specific HIV prevalence estimates are widely available at the national level, and region-wide local estimates were recently published for adults overall. We add further dimensionality to previous analyses by estimating HIV prevalence at local scales, stratified into sex-specific 5-year age groups for adults ages 15-59 years across SSA. METHODS: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 countries in SSA, from years 2000 to 2018, at a 5 × 5-km resolution and presented among second administrative level (typically districts or counties) units. RESULTS: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence differences between age groups: for men, 50% of districts displayed at least a 14-fold difference between age groups with the highest and lowest prevalence, and at least a 9-fold difference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than five percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a five percentage point prevalence increase in one or more sex and age group. CONCLUSIONS: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment efforts are necessary. These estimates offer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA

    BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. FINDINGS: The number of people aged 30-79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306-359) million women and 317 (292-344) million men in 1990 to 626 (584-668) million women and 652 (604-698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55-62) of women and 49% (46-52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43-51) of women and 38% (35-41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20-27) for women and 18% (16-21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. INTERPRETATION: Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings.
