- The 24-Hour Activity Checklist for Cerebral Palsy: Translation, Content Validity and Test-Retest Reliability of Portuguese VersionsPublication . Vila-Nova, Fabio; Sá, Cristina; Leite, Hércules Ribeiro; Cadete, Ana; Folha, Teresa; Longo, Egmar; Martins, Maria Elisabete; Oliveira, RaulBackground: The importance of 24-h movement behaviour, including sleep, physical activity (PA) and sedentary behaviour (SB), has gained prominence due to its significant impact on the health and development of children, including those with cerebral palsy (CP). The 24-h activity checklist for CP, a tool developed in the Netherlands to monitor the activity in CP paediatric population, requires translation and cultural adaptation to Portuguese for use in Brazil and Portugal. Methods: This cross-sectional methodological study involved translating and culturally adapting the 24-h activity checklist for CP into Brazilian Portuguese (BP) and European Portuguese (EP) languages. The process included forward translation, synthesis and backward translation, expert panel evaluation and pretesting. Brazilian and Portuguese experts appraised content validity, assessed by the individual item (I-CVI) and scale level content validity index scores (S-CVI/Ave). Sixty parents of children with CP participated in the test-retest analysis, reported with the Intraclass Correlation Coefficients (ICCs). Results: I-CVI scores were higher than 0.78 for both versions. S-CVI/Ave scores were considered excellent for BP (0.91) and EP version (1.0). Expert's appraisal results in the inclusion of a question about sleep-related time indicators and the split of sleep, PA, and screen time questions for weekdays and weekends. Brazilian and Portuguese parents of children with CP reported understanding on instructions, questions, and answer options. The ICC values range from 0.81 to 0.99 and 0.6 to 0.98, for BP and EP, respectively. Conclusions: The BP and EP versions of 24-h activity checklist for CP demonstrated good content validity and test-retest reliability, supporting its use in Brazil and Portugal. This tool can contribute to improving communication between families and healthcare professionals to monitor and develop tailored interventions for healthy movement behaviours in children with CP.
- Burden of Disease and Cost of Illness of Overweight and Obesity in PortugalPublication . Borges, Margarida; Sampaio, Filipa; Costa, João; Freitas, Paula; Matias Dias, Carlos; Gaio, Vânia; Conde, Vasco; Figueira, Débora; Pinheiro, Bernardete; Silva Miguel, LuísIntroduction: The prevalence of overweight and obesity has increased in the last decades, posing significant health and economic impacts globally. These conditions are related to several non-communicable diseases, including cardiovascular disease, type II diabetes, and cancer. This study estimated the disease burden and healthcare costs associated with overweight and obesity in the adult population in mainland Portugal, in 2018. Method: Burden of disease was measured in disability-adjusted life years (DALYs) following Global Burden of Disease (GBD) methodology. DALYs were calculated as the sum of years of life lost (YLL) and years lived with disability (YLD). The analyses included morbidity, mortality, and related costs directly related to overweight and obesity, as well as the attributable morbidity, mortality, and related costs of 25 selected diseases related to obesity (DrO). A prevalence-based cost analysis was conducted a from the perspective of the public National Health Service, including costs related to inpatient, outpatient care, and pharmacological treatment. Results: In 2018, total DALY amounted to 260,943, with 75% due to premature death (196,438 YLL) and 25% due to disability (64,505 YLD). The economic burden of overweight and obesity was estimated at approximately EUR 1,148 million. Of these, approximately EUR 13.3 million (1%) were costs related to the treatment of obesity, and the remaining were costs of DrO attributed to overweight and obesity. Outpatient care corresponded to 43% of total costs, pharmacological treatment 38%, and inpatient care 19%. Cardiovascular and cerebrovascular diseases were the largest contributor to total costs (38%), followed by type II diabetes (34%). Conclusion: Overweight and obesity incur a large disease and economic burden to the public healthcare sector, representing approximately 0.6% of the country's gross domestic product and 5.8% of public health expenditures.

Rojas-Castro, Madelyn; Verdasca, Nuno; Monge, Susana; De Mot, Laurane; Trobajo-Sanmartín, Camino; Duffy, Róisín; Túri, Gergő; Kuliese, Monika; Duerrwald, Ralf; Borg, Maria-Louise; Popovici, Odette; Gomez, Verónica; Makarić, Zvjezdana Lovrić; Launay, Odile; Marques, Diogo F.P.; Pozo, Francisco; Witdouck, Arne; Martínez-Baz, Iván; Fitzgerald, Margaret; Oroszi, Beatrix; Jančorienė, Ligita; Buda, Silke; Dziugyte, Ausra; Lazăr, Mihaela; Machado, Ausenda; Tabain, Irena; Nguyen, Liem Binh Luong; Wagner, Eva Rivas; Dufrasne, François; Castilla, Jesús; Domegan, Lisa; Velkey, Viktória; Majauskaite, Fausta; Hackmann, Carolin; Nicolay, Nathalie; Bacci, Sabrina; Rose, Angela M.C.; European Hospital Vaccine Effectiveness GroupWe estimated COVID-19 vaccine effectiveness (VE) against PCR-confirmed SARS-CoV-2 hospitalization in patients ≥ 60 years with severe acute respiratory infection, using a multicenter, test-negative, case-control study across seven sites in six European countries between September 2024 and May 2025. We included 352 cases (115 vaccinated; 33%) and 9980 controls (5024 vaccinated; 50%). VE was 42% (95% CI: 15; 61) 14-59 days post-vaccination, 32% (95% CI: -1; 54) at 60-119 days, and 36% (95% CI: 2; 60) at 120-179 days, and no effect thereafter. Among adults aged 60-79 and ≥ 80 years, we observed moderate VE against COVID-19 hospitalization for up to 2 and 4 months, respectively.
- Effectiveness of the XBB.1.5 COVID-19 Vaccines Against SARS-CoV-2 Hospitalisation Among Adults Aged ≥ 65 Years During the BA.2.86/JN.1 Predominant Period, VEBIS Hospital Study, Europe, November 2023 to May 2024Publication . Antunes, Liliana; Rojas-Castro, Madelyn; Lozano, Marcos; Martínez-Baz, Iván; Leroux-Roels, Isabel; Borg, Maria-Louise; Oroszi, Beatrix; Fitzgerald, Margaret; Dürrwald, Ralf; Jancoriene, Ligita; Machado, Ausenda; Petrović, Goranka; Lazar, Mihaela; Součková, Lenka; Bacci, Sabrina; Howard, Jennifer; Verdasca, Nuno; Basile, Luca; Castilla, Jesús; Ternest, Silke; Džiugytė, Aušra; Túri, Gergő; Duffy, Roisin; Hackmann, Carolin; Kuliese, Monika; Gomez, Verónica; Makarić, Zvjezdana Lovrić; Marin, Alexandru; Husa, Petr; Nicolay, Nathalie; Rose, Angela M. C.; VEBIS SARI VE network teamWe estimated the effectiveness of the adapted monovalent XBB.1.5 COVID-19 vaccines against PCR-confirmed SARS-CoV-2 hospitalisation during the BA.2.86/JN.1 lineage-predominant period using a multicentre test-negative case-control study in Europe. We included older adults (≥ 65 years) hospitalised with severe acute respiratory infection from November 2023 to May 2024. Vaccine effectiveness was 46% at 14-59 days and 34% at 60-119 days, with no effect thereafter. The XBB.1.5 COVID-19 vaccines conferred protection against BA.2.86 lineage hospitalisation in the first 4 months post-vaccination.
- Epidemiology of Falls Among Older Adults in Portugal: Analysis of Unintentional Injuries Reported by a National Emergency Surveillance SystemPublication . JORGE SILVA ALVES, TATIANA DANIELA; das Neves Pereira da Silva, Susana; Braz, Paula; Papadakaki, Maria; Aniceto, Carlos; Mexia, Ricardo; Dias, Carlos MatiasBackground/Objectives: Falls occurring at home and during leisure time among elderly individuals represent a serious public health issue in Portugal and worldwide. These incidents have a significant impact on healthcare systems and social support structures, as well as the personal and family lives of the victims. There is also a recognized gap in awareness among older adults regarding fall prevention, particularly regarding environmental hazards, the need for home modifications, and the adoption of safety behaviors, including necessary adjustments in their home environments. The present study was developed to enhance our understanding of the circumstances in which falling occurs in elderly people. Methods: A cross-sectional epidemiological study was carried out, analyzing data collected through the national emergency-based injury surveillance system in 2023. Results: The proportion of falls increased across age groups, with 34.9% of total falls occurring in the group aged 85 and over. These differences were statistically significant (p < 0.001). In all age groups, falls were more frequent among women, representing between 63.6% and 69.0% of episodes. Approximately 65.9% of falls occurred at home. The likelihood of falling was higher among the oldest age group (85+) and in the home. Conclusions: The results of this study confirm that falls in elderly people tend to occur more frequently with advancing age, particularly in environments where the most time is spent. This study suggests that fall-prevention campaigns should be specifically targeted towards older females in the home environment, with particular consideration given to morning routines as part of the recommended interventions.
- Influenza vaccine effectiveness in Europe and the birth cohort effect against influenza A(H1N1)pdm09: VEBIS primary care multicentre study, 2023/24Publication . Kissling, Esther; Maurel, Marine; Pozo, Francisco; Pérez-Gimeno, Gloria; Buda, Silke; Sève, Noémie; Domegan, Lisa; Hooiveld, Mariëtte; Oroszi, Beatrix; Martínez-Baz, Iván; Guiomar, Raquel; Latorre-Margalef, Neus; Mlinarić, Ivan; Lazar, Mihaela; Giménez Duran, Jaume; Dürrwald, Ralf; Enouf, Vincent; McKenna, Adele; de Lange, Marit; Túri, Gergő; Trobajo-Sanmartín, Camino; GOMEZ TEIXEIRA PINTO, VERÓNICA DEL PILAR; Samuelsson Hagey, Tove; Višekruna Vučina, Vesna; Cherciu, Maria Carmen; García Vazquez, Miriam; Erdwiens, Annika; Masse, Shirley; Bennett, Charlene; Meijer, Adam; Kristóf, Katalin; Castilla, Jesús; Rodrigues, Ana Paula; Kurečić Filipović, Sanja; Ivanciuc, Alina Elena; Bacci, Sabrina; Kaczmarek, MarlenaIntroduction: Influenza A(H1N1)pdm09, A(H3N2) and B/Victoria viruses circulated in Europe in 2023/24, with A(H1N1)pdm09 dominance. First influenza infections in childhood may lead to different vaccine effectiveness (VE) in subsequent years. Aim: The VEBIS primary care network estimated influenza VE in Europe using a multicentre test-negative study. Methods: Primary care practitioners collected information and specimens from patients consulting with acute respiratory infection. We estimated VE against influenza (sub)type and clade, by age group and by year of age for A(H1N1)pdm09, using logistic regression. Results: We included 29,958 patients, with 3,054, 1,053 and 311 influenza A(H1N1)pdm09, A(H3N2) and B cases, respectively. All-age VE against influenza A(H1N1)pdm09 was 52% (95% CI: 44-59). By year of age, VE was 27% (95% CI: -2 to 47) at 44 years with peaks at 72% (95% CI: 52-84) and 54% (95% CI: 41-64) among children and those 65 years and older, respectively. All-age A(H1N1)pdm09 VE against clade 5a.2a was 41% (95% CI: 24-54) and -11% (95% CI: -69 to 26) against clade 5a.2a.1. The A(H3N2) VE was 35% (95% CI: 20-48) among all ages and ranged between 34% and 40% by age group. All-age VE against clade 2a.3a.1 was 38% (95% CI: 1-62). All-age VE against B/Victoria was 83% (95% CI: 65-94), ranging between 70 and 92% by age group. Discussion: The 2023/24 VEBIS primary care VE against medically attended symptomatic influenza infection was high against influenza B/Victoria, but lower against influenza A(H1N1)pdm09 and A(H3N2). Clade- and age-specific effects may have played a role in the lower A(H1N1)pdm09 VE.
- Interim 2024/25 influenza vaccine effectiveness: eight European studies, September 2024 to January 2025Publication . Rose, Angela; Lucaccioni, Héloïse; Marsh, Kimberly; Kirsebom, Freja; Whitaker, Heather; Emborg, Hanne-Dorthe; Botnen, Amanda Bolt; O’Doherty, Mark G.; Pozo, Francisco; Shahul Hameed, Safraj; Andrews, Nick; Hamilton, Mark; Lauenborg Møller, Karina; Trebbien, Ramona; Marques, Diogo F.P.; European IVE groupThe 2024/25 influenza season in Europe is currently characterised by the co-circulation of influenza A(H1N1)pdm09, A(H3N2) and B/Victoria viruses, with influenza A(H1N1)pdm09 predominating. Interim vaccine effectiveness estimates from eight European studies conducted in 17 countries indicate an overall influenza A vaccine effectiveness of 32–53% in primary care settings and 33–56% in hospital settings, with some indications of lower effectiveness by subtype and higher effectiveness against influenza B (≥58% across settings). Where feasible, influenza vaccination should be encouraged and other preventive measures strengthened.
- Perceptions of Fall Prevention and Engagement in Social Prescribing Activities Among Older Adults: A Cross-Sectional Study in PortugalPublication . Matos, Cristiano; Baixinho, Cristina Rosa; Alarcão, Violeta; Henriques, Maria Adriana; Ferreira, Ricardo Oliveira; Nascimento, Tiago; Arriaga, Miguel; JORGE SILVA ALVES, TATIANA DANIELA; Nogueira, Paulo; Costa, AndreiaBackground: Falls are a major cause of injury, functional decline, and reduced quality of life among older adults, posing a significant public health challenge. Social prescribing is gaining relevance in gerontology, offering structured strategies to engage individuals in preventive activities, including fall prevention strategies, through engagement in community-based activities. Aim: To examine older adults' perception of the relevance of personal protection and development activities (e.g., prevention against falling) and compare sociodemographic, behavioural, and engagement profiles between those who agree and those who disagree with its relevance. Methods: A cross-sectional study was conducted with 613 older adults aged 65-93 years. Data collection included sociodemographic, health-related, and behavioural/social engagement variables (including perceptions regarding the benefits of social prescribing and interest in community-based activities). For this analysis, participants were dichotomized based on their agreement with the relevance of personal protection and development activities (e.g., prevention against falling). Of the 569 participants included, 538 (94.5%) agreed with its relevance and 31 (5.5%) disagreed. Descriptive and exploratory analyses were conducted to compare the two groups across variables. Multivariate logistic regression analyses were conducted to explore independent predictors of agreement across sociodemographic, behavioural, social prescribing, and health-related variables. Results: Significant differences were observed between the groups in awareness of active ageing (p = 0.018), volunteering (p < 0.001), participation in social and community activities (p < 0.001), and hobbies like gardening, fishing, or cooking (p = 0.002). Those who agreed with the importance of personal protection and development activities were significantly more likely to value a range of initiatives, including social activities in recreational organizations, physical activity in the community (e.g., hiking), artistic and creative activities (e.g., visual arts, music), technical or technological activities (e.g., do-it-yourself, computers), and cultural enrichment activities (e.g., visiting museums), (p < 0.001). Multivariate analyses showed no effects of sociodemographic or health-related factors, whereas behavioural and engagement-related variables-including volunteering, hobbies, and several social prescribing activities-significantly predicted agreement with the relevance of personal protection and development activities. Discussion: The findings suggest that older adults who perceive fall prevention as relevant are more actively engaged in diverse health-promoting activities, including volunteering, hobbies, and community-based programmes. This pattern may reflect higher health literacy, stronger social networks, and proactive attitudes towards ageing. Conclusions: Perceptions of fall prevention are closely linked to broader patterns of engagement in health-promoting activities among older adults. Recognizing and addressing differences in how these activities are valued can inform more inclusive and targeted gerontological interventions.
- Recommendations for estimating and reporting vaccine effectiveness by time since vaccination: a COVID-19 case studyPublication . Kissling, Esther; Nunes, Baltazar; Hooiveld, Mariëtte; Martínez-Baz, Iván; Monge, Susana; Robertson, Chris; Knolm, Mirjam; Sève, Noémie; Mlinarić, Ivan; Domegan, Lisa; Machado, Ausenda; Whitaker, Heather; Lazar, Mihaela; Meijer, Adam; Enkirch, Theresa; Casado, Itziar; Pérez-Gimeno, Gloria; William, Naoma; Enouf, Vincent; Kurečić Filipović, Sanja; McKenna, Adele; Rodrigues, Ana Paula; de Lusignan, Simon; Timnea, Olivia-Carmen; Latorre-Margalef, Neus; Castilla, Jesús; Pozo, Francisco; Hamilton, Mark; Masse, Shirley; Ilić, Maja; Basile, Luca; O’Donnell, Joan; Guiomar, Raquel; Riess, Maximilian; Popescu, Rodica-Manuela; M C Rose, Angela; Andrews, Nick; Bacci, Sabrina; Pastore Celentano, Lucia; Valenciano, Marta; Moren, Alain; Beutels, Philippe; Hens, Niel; I-MOVE-COVID-19 and ECDC primary care study teamsEstimating COVID-19 vaccine effectiveness (VE) by time since vaccination (TSV) is essential for understanding how protection may change over time and enables meaningful comparisons across studies. This is important for accurate comparisons of VE against different SARS-CoV-2 variants/sublineages, across age groups, during different periods post vaccination campaign, or by vaccine type/brand. We provide recommendations for case–control VE studies on estimating and reporting VE analyses by TSV, with the aim of improving quality of these estimates. Our recommendations cover study design and pre-analysis considerations, descriptive analyses, choice of categories of TSV, categorical and continuous modelling approaches, and best practices for reporting VE by TSV. Using a real-life case–control study, we apply these recommendations, and include accompanying statistical scripts in R and Stata. These recommendations will serve as a practical resource for researchers conducting VE analyses by TSV. We encourage ongoing refinement of them through input from other study groups.
- Rural–urban differences in healthcare utilization across different outcomes in PortugalPublication . Martinho, Júlia; Leite, AndreiaBackground: Urbanization influences healthcare access and utilization, contributing to health disparities. This study aims to assess the effect of degree of urbanization on healthcare utilization in Portugal, where urbanization levels are above global average. Methods: Utilizing data from the 2019 National Health Survey, this cross-sectional study analyzed the association between degree of urbanization and outcomes including general and specialist consultations, flu vaccination, colonoscopy, and wait times. Adjusted prevalence ratios (aPR) were estimated using Poisson regression models. Results: Less populated areas had increased wait times (aPR = 1.54; 95% confidence intervals [95% CI]: 1.06-2.24) and lower colonoscopy utilization (aPR = 0.86; 95% CI: 0.78-0.95). Flu vaccination rates were higher in rural (aPR = 1.15; 95% CI: 1.03-1.30) and suburban areas (aPR = 1.16; 95% CI: 1.04-1.30). No significant association was found for general/specialist consultations or excessive wait times. Conclusions: Geographic constraints limit healthcare access in less populated areas. Urban areas showed suboptimal flu vaccination rates, suggesting a need for improved immunization strategies. Addressing geographical disparities is crucial for ensuring equitable healthcare access across Portugal.
