- Adesão ao Rastreio do Cancro do Colo do Útero e da Mama da Mulher PortuguesaPublication . Ferreira, Manuela; Ferreira, Sofia; Ferreira, Nuno; Andrade, Joana; Duarte, JoãoResumo Enquadramento: O aumento das doenças oncológicas na mulher é uma preocupação, tanto pelo impacto na sua qualidade de vida, como nos indicadores de saúde e nos custos, assumindo por isso vital importância a adesão das mulheres ao rastreio precoce. Objetivos: Identificar os fatores associados à adesão das mulheres à vigilância de saúde sexual e reprodutiva. Método: Trata-se de um estudo de natureza quantitativa, não experimental, descritivo, correlacional e transversal, com uma amostra constituída por 522 mulheres, com idades compreendidas entre os 18 e os 67 anos, que frequentam os cuidados de saúde primários portugueses, no ACES Dão Lafões. Resultados: As mulheres que participaram no estudo tem uma média de idade ≤ 30 anos (25,7%), possuem maioritariamente o ensino secundário (38,5%), são casadas ou em união de facto (62,8%), têm nacionalidade portuguesa 97.7%, residem com o companheiro (72,8%), e a maioria tem 2 filhos (33.9%). Verificámos que os grupos etários, o estado civil, o agregado familiar, as habilitações literárias, a profissão e o número de filhos foram preditores da adesão à vigilância de saúde sexual e reprodutiva. A realização do autoexame da mama e os conhecimentos acerca do cancro do colo do útero mostraram ser preditores da adesão à vigilância de saúde sexual e reprodutiva. Conclusão: Os profissionais de saúde devem adotar práticas de rastreio e promover decisões informadas e seguras para a saúde das mulheres. As recomendações médicas para realização do autoexame da mama e citologia, bem como as características sociodemográficas, devem ser consideradas pelos profissionais de saúde na promoção da saúde sexual e reprodutiva da mulher.
- Health literacy and its determinants among pregnant women in PortugalPublication . Ferreira, Nuno; Ferreira, Manuela; Santos, Eduardo José Ferreira; Ferreira, Sofia; Arriaga, Miguel Telo; Costa, AndreiaBackground Health literacy is a key determinant of health outcomes and equity, particularly during pregnancy, a period marked by increased information needs and critical health decisions. Despite its importance, data on health literacy among pregnant women in Portugal remain scarce. This study aimed to assess general health literacy levels and their associations with sociodemographic, health-related, and pregnancy-specific factors in a large sample of pregnant women from the district of Viseu, Portugal. Methods A cross-sectional study was conducted with 886 pregnant women aged 18 years or older, using the validated HLS19-Q12 instrument to measure general health literacy. Data collection occurred between October 2023 and May 2024 using a multimodal approach (online, interview, and paper-based). Health literacy was categorized into four levels and also dichotomized as limited versus not limited. Descriptive statistics, bivariate analyses, and binary logistic regression were performed to identify determinants of limited health literacy. Results The mean general health literacy score was 68.3 (SD±10.9). A total of 46.7% of participants were classified as having limited health literacy. Among the pregnant women surveyed, 18.8% were born outside Portugal. Of these, 74.7% were classified as having limited health literacy, compared to 40.2% among Portuguese-born participants. Higher prevalence was observed among women aged 18–29, those born outside Portugal, with lower education, in undifferentiated professions, and facing financial hardship. In the final adjusted logistic regression model, which combined variables selected through forward stepwise inclusion with theoretically important covariates entered in a second block, significant predictors of limited health literacy included being born outside Portugal (adjusted OR 2.43; 95% CI: 1.56–3.80), having lower education (up to high school), holding lower-skilled occupations, financial difficulties, and rating current health as equal or worse. Pre-pregnancy Body Mass Index was also negatively associated with health literacy levels, with higher BMI more prevalent among women with limited health literacy. The model showed good discriminatory ability (area under the ROC curve=0.78). Conclusions A considerable proportion of pregnant women demonstrated limited health literacy, particularly among socioeconomically vulnerable and migrant groups. These findings underscore the urgency of adopting antenatal care approaches that are responsive to health literacy needs. Incorporating brief assessments during early prenatal visits, using plain language and visual communication tools, and offering targeted support to high-risk groups may enhance informed decision-making, promote equity, and improve maternal and neonatal outcomes.
- ValNuts - Valuation of hard shell nuts (FSCR)Publication . Correia, Paula; Guiné, Raquel; Ferrão, Ana Cristina; Elsa, Ramalhosa; Ribeiro, Carlos; Silva, Carlos; Droga, Rui; Ferreira, Nuno; Araújo, JoanaThe hard-shell nuts sector (FSCR) plays a fundamental role in the sustainability of the economies of the rural regions in Portugal. The characterization of varieties, as well as the identification of factors and possible preventive activities could avoid the appearance of defects in these fruits (e.g. bitterness), and also value these fruits for different purposes, such as cooking, cosmetics and pharmaceutical industry. The lack of knowledge by producers as to the best processes for the conservation of nuts can lead to considerable economic losses, leading to significant defects (e.g. rancid). Also, industrial producers face serious problems when they export FSCRs to tropical countries (which are important customers) as they have to deal with environments with high humidity, high temperatures, and long transport times. Hence, this project aims to enhance the production of hard-shell nuts in Portugal, with a view to boosting its production, increasing its economic value and promoting the export capacity of FSCR producers. The project was desigedn to study almonds, hazelnuts and walnuts, and it is divided in three stages: promotion and characterization of nuts varieties existent in Portugal, post-harvest technologies - process and product innovation, and transfer of knowledge and dissemination of results. the first stage intends to determine the most important varieties commercialize in Portugal using a survey applied to producers. after the identification, these varieties are characterized considering the physicochemical, biological and sensorial properties. establishment of good practices to be followed by FSCR producers and their effect on fruit quality are also other tasks, following some producers through the creation of working groups. The second stage is constituted by five activities: (1) Characterization of the storage and distribution conditions that FSCRs in shell (walnut), kernel (hazelnut and almond) and laminates (almond) are subject during national and European commercialization and determination of the main problems; (2) Characterization of fluvial transport conditions to which kernel and almond laminates are subjected when exported to tropical countries; (3) Characterization of the main physical, chemical, biological and sensorial agents responsible for the losses of quality of the almond exported to tropical countries; (4) Evaluation of the behavior and adaptability to the environmental conditions of transport to tropical countries of several varieties of almond; (5) Implementation of effective post-harvest technologies to promote the export of FSCRs to Europe and tropical countries. The last stage wants to create some focal groups, a webpage of the project, as well as to develop of informative brochures, seminars and publications. The obtained results will be most valuable to produce relevant technical and scientific outputs as well as directives that could be used by the producers and industrials to improve the hard-shell nuts’ sector.
