    Introduction: There are no studies that have assessed potential risk factors (RFs) for the development of eating disorders (EDs) in males, considering the onset of an ED and controlling for the development of initial symptoms or preceding RFs. This case series was conducted with males and aimed to describe the clinical features and symptomatic onset of EDs, to characterize male puberty development and to identify potential RFs for EDs and specific life events preceding ED symptoms. Methods: Ten males ED patients participated in this study. All participants were interviewed with the Eating Disorders Examination, the Oxford Risk Factor Interview and a semi-structured clinical interview for the evaluation of males’ puberty development. Results: Almost all participants began their EDs with dieting. Half of the participants mentioned the development of muscle mass and experiences of embarrassment related to undressing in front of their peers, both of which were associated with suffering and peers teasing. A history of peer aggression and/or teasing was the only RF experienced by all the participants. We found the presence of RFs in all the remaining evaluated domains. Conclusions: In line with previous RF studies with female samples, we found an ED aetiology that is multifactorial in nature.

  • Enhancing optimization planning models for health human resources management with foresight

    Achieving a balanced healthcare workforce requires health planners to adjust the supply of health human resources (HHR). Mathematical programming models have been widely used to assist such planning, but the way uncertainty is usually considered in these models entails methodological and practical issues and often disregards radical yet plausible changes to the future. This study proposes a new socio-technical methodology to factor in uncertainty over the future within mathematical programming modelling. The methodological approach makes use of foresight and scenario planning concepts to build tailor-made scenarios and scenario fit input parameters, which are then used within mathematical programming models. Health stakeholders and experts are engaged in the scenario building process. Causal map modelling and morphological analysis are adopted to digest stakeholders and experts’ information about the future and give origin to contrasting and meaningful scenarios describing plausible future. These scenarios are then adjusted and validated by stakeholders and experts, who then elicit their best quantitative estimates for coherent combinations of input parameters for the mathematical programming model under each scenario. These sets of parameters for each scenario are then fed to the mathematical programming model to obtain optimal solutions that can be interpreted in light of the meaning of the scenario. The proposed methodology has been applied to a case study involving HHR planning in Portugal, but its scope far extends HHR planning, being especially suited for addressing strategic and policy planning problems that are sensitive to input parameters.
