Underlying Factors Associated with Anemia in Amazonian Children: A Population-Based, Cross-Sectional Study

Background: Although iron deficiency is considered to be the main cause of anemia in children worldwide, other contributors to childhood anemia remain little studied in developing countries. We estimated the relative contributions of different factors to anemia in a population-based, cross-sectional survey. Methodology: We obtained venous blood samples from 1111 children aged 6 months to 10 years living in the frontier town of Acrelandia, northwest Brazil, to estimate the prevalence of anemia and iron deficiency by measuring hemoglobin, erythrocyte indices, ferritin, soluble transferrin receptor, and C-reactive protein concentrations. Children were simultaneously screened for vitamin A, vitamin B-12, and folate deficiencies; intestinal parasite infections; glucose-6-phosphate dehydrogenase deficiency; and sickle cell trait carriage. Multiple Poisson regression and adjusted prevalence ratios (aPR) were used to describe associations between anemia and the independent variables. Principal Findings: The prevalence of anemia, iron deficiency, and iron-deficiency anemia were 13.6%, 45.4%, and 10.3%, respectively. Children whose families were in the highest income quartile, compared with the lowest, had a lower risk of anemia (aPR, 0.60; 95% CI, 0.37-0.98). Child age (<24 months, 2.90; 2.01-4.20) and maternal parity (>2 pregnancies, 2.01; 1.40-2.87) were positively associated with anemia. Other associated correlates were iron deficiency (2.1; 1.4-3.0), vitamin B-12 (1.4; 1.0-2.2), and folate (2.0; 1.3-3.1) deficiencies, and C-reactive protein concentrations (>5 mg/L, 1.5; 1.1-2.2). Conclusions: Addressing morbidities and multiple nutritional deficiencies in children and mothers and improving the purchasing power of poorer families are potentially important interventions to reduce the burden of anemia.Sao Paulo State Research Agency [FAPESP 07/53042-1]Sao Paulo State Research AgencyNational Research Agency of BrazilNational Research Agency of Brazil [CNPq 470573/2007-4

Percepção das usuárias sobre as ações de Prevenção do Câncer do Colo do Útero na Estratégia Saúde da Família em uma Distrital de Saúde do município de Ribeirão Preto, São Paulo, Brasil User perception on the actions of Cervix Cancer Prevention of Family Health Strategy in a Health District of the municipality of Ribeirão Preto, in São Paulo, Brazil

OBJETIVOS: analisar a percepção das mulheres atendidas nas Unidades de Saúde da Família (USF), da Área Básica de uma Distrital de Saúde do Município de Ribeirão Preto, São Paulo, sobre as práticas de Prevenção do câncer do colo do útero (PCCU) desenvolvidas nestes serviços. MÉTODOS: utilizou-se como referencial teórico a Atenção Primária à Saúde (APS). Trata-se de uma pesquisa de abordagem qualitativa, do tipo exploratória e descritiva. Foram entrevistadas 14 mulheres. Utilizou-se para coleta de dados a entrevista semi-estruturada, procedendo à análise dos dados, orientados pela análise temática. A análise dos dados foi estruturada em três temas: Temática 1 - O Olhar da Mulher sobre o Processo Saúde-Doença; Temática 2 - A Mulher e a Prevenção do Câncer do Colo do Útero; Temática 3 - As Práticas de Prevenção do Câncer do Colo do Útero nos Núcleos de Saúde da Família. RESULTADOS: a maioria das mulheres envolvidas apresentam um conceito holístico de saúde, tendo inclusive um conhecimento popular bastante elaborado do conceito de prevenção. CONCLUSÕES: as práticas de educação em saúde precisam ser reforçadas a partir da inclusão de toda equipe. As USF têm potencialidades para qualificar a prática da PCCU e promover maior integralidade das ações em saúde, utilizando o conhecimento da APS.<br>OBJECTIVES: to analyze the perception of women seen at the Family Health Units (FHU) of the Basic Health District in the municipality of Ribeirão Preto, São Paulo, on the practices of cervix cancer prevention developed by these services. METHODS: a theoretical reference of primary healthcare was utilized. This is a qualitative survey of the exploratory, descriptive type. Fourteen women were interviewed. A semi-structured interview was used for data collection, data analysis oriented by thematic analysis. Data analysis was structured in three themes: Theme 1 - Women's view of the Health-Disease Process; Theme 2 - Women and Cervix Cancer Prevention; Theme 3: Cervix Cancer Prevention in Family Health Centers. RESULTS: the majority of women involved demonstrated a holistic concept of health and a rather elaborate concept of prevention. CONCLUSIONS: education practices in healthcare need to be reinforced based on staff inclusion. Family Health Units have the potential to improve cervix cancer prevention practices and to further integrate primary health care programs

Agroecological management of cucurbit-infesting fruit fly: a review

Conventional crop protection with pesticides has limitations such as resistance of pests to pesticides and faunal imbalance. Agroecological crop protection is an attractive alternative based on the principles of agroecology. We present here this strategy using the case of Cucurbitaceae flies, which are the most important agricultural pests in Réunion. Research has been carried out on the bioecology of these insects and on the effectiveness of agroecological techniques. The main points are the following: the number of species of vegetable flies increased in the southern summer. Adult flies spend more than 90 % of their time on nonhost plants, with specific circadian rhythms. Several original agroecological techniques were designed, such as sanitation using augmentoria; trap plants, e.g., maize; adulticide bait; and the creation of habitats for predatory arthropods. Local growers are very satisfied with the results. They have reduced insecticide use with substantial cost savings and they have observed a decrease in losses and a lower phytosanitary workload. The education and training of students, professionals, and the general public has been a major aspect of this project. Increased knowledge of flies and agroecological management strategies of their populations can now be combined with modeling tools to facilitate the extension of the program to other areas or for educational purposes. Practices are currently being extended to other areas of the island and other countries of the Indian Ocean. This project is both a significant milestone for organic farming in Réunion and a precedent for other initiatives aimed at reducing or eliminating pesticides
