Objectives. - Esports are an increasingly popular activity that involves professional players. Dehydration hinders cognitive performance, on which these competitors rely heavily. This observational study assessed the hydration state of esports players on a competition day and its possible associations with esports and lifestyle-related features. Methods. - The hydration status of esports players was assessed on...
Key messages: Chronicity and social context influence COVID-19 risk highlighting its syndemic dimension Record Linkage advances knowledge on COVID-19, associated chronic diseases, and social indicators Further harmonization of data protection requirements for scientific research may create multilevel public health measures As a multidimensional tool, it optimizes integrated strategies and fosters solidarity on ...
Background: Preterm birth is a global health concern. Its adverse consequences may persist throughout the life course, exerting a potentially heavy burden on families, health systems, and societies. In high-income countries, the first children who benefited from improved care are now adults entering middle age. However, there is a clear gap in the knowledge regarding the long-term outcomes of individuals born p...
Background: Few studies examine the relationship between socioeconomic factors and trends in mortality in high-income European countries. Due to the lack of regional-level data, most recent studies on social inequality in Portugal do not investigate regional differences. This study analyses time trends and regional disparities in the evolution of perinatal mortality (PMR) and infant mortality (IMR) associated w...
The timely identification of cohort participants at higher risk for attrition is important to earlier interventions and efficient use of research resources. Machine learning may have advantages over the conventional approaches to improve discrimination by analysing complex interactions among predictors. We developed predictive models of attrition applying a conventional regression model and different machine le...
Objective: To understand participation and attrition phenomena variability in European cohorts of individuals born preterm through in-depth exploration of the interplay of situational elements involved. Methods: Multi-situated qualitative design, using focus groups, semi-structured interviews and collaborative visual methodology with a purposive sample of adults born preterm, parents and professionals (n = 124)...
Background: Birth cohorts provided essential knowledge for clinical and public health decision-making. However, little is known about retention and determinants of attrition in these specific longitudinal studies, although characterizing predictors of attrition sets the path to mitigate its occurrence and to promote valid inferences. We systematically reviewed retention in follow-ups of birth cohorts of very pr...
Background The long-term follow-up of very preterm and very low birthweight cohorts contributes to valuable evidence to understand life-course outcomes in these vulnerable populations. However, attrition is a major challenge in long-term outcome studies. Examining the techniques used by existing cohorts may help to reveal practices that enhance willingness to continue participation over time. Objectives To eval...
