  • Portuguese expatriates’ health in Angola and Mozambique—a cross-sectional study: increasing awareness and need for more surveillance
    Publication . Fonseca, Ana Glória; Dias, Sara S.; Baptista, João Luis; Torgal, Jorge
    Background: Increasing numbers of expatriates are working in sub-Saharan Africa. There is little published data on the complex population and this survey aimed at understanding expatriate morbidity by accessing self-reported health problems and malaria preventive practices. Methods: A cross-sectional web-based survey was conducted targeting Portuguese expatriates in Angola and Mozambique. Logistic regression analysis explored factors associated with self-reported health problems and psy chological symptoms in the previous 3 months. Results: A total sample of 352 adult Portuguese urban civil occupational expatriates was obtained. Median length of expatriation was 3 years. Considering a 3-month timeframe, one in five expatriates reported new health problems and need of medical assistance, 5% were hospitalized and 64% reported general psychological symptoms. Less than 2% of subjects were on malaria chemoprophylaxis. Having chronic health conditions doubled the reporting of new health problems. Increasing length of expatriation was associated with decreasing reporting of general psychologi cal symptoms. Directors and executive managers and expatriates living alone tended to report more general psy chological symptoms. Conclusion: Expatriate communities deserve enhanced surveillance for the health issues that affect them. This will improve evidence-based preparation and intervention by public and travel health practitioners.

  • Surveillance of imported hospital requiring malaria in Portugal: can it be improved?: Table 1
    Publication . Fonseca, Ana Glória; Dias, Sara; Baptista, João Luís; Torgal, Jorge
    Although eradicated in Portugal, malaria keeps taking its toll on travellers and migrants from endemic countries. Completeness of hospital requiring malaria notification in Portugal 2000–11 was estimated, using two-source capture–recapture method. Data sources were: national surveillance database of notifiable diseases and the national database of the Diagnosis-Related Groups resulting from National Health Service (NHS) hospital episodes. The completeness of notification was 21,2% for all malaria cases and 26,5% for malaria deaths, indicating significant underreporting and urging for complementary data source in surveillance, for disease burden estimates and retrospective monitoring, namely hospital episodes statistics.

  • Validação Exploratória e Confirmatória da Escala de Resiliência Connor-Davidson (CD-RISC-10) numa Amostra de Inscritos em Centros de Emprego
    Publication . Almeida, Maria Helena; Dias, Sara; Xavier, Miguel; Torgal, Jorge
    Introdução: Bonanno definiu resiliência como a capacidade do indivíduo em lidar com os eventos traumáticos, nomeadamente a capacidade de manter os níveis de funcionamento físico e psicológico relativamente estáveis. O objetivo do estudo foi avaliar as propriedades psicométricas da escala de resiliência Connor-Davidson de 10 itens. A escala resumida apresenta boas qualidades psicométricas (α Cronbach – 0,85) quando comparada com a escala longa (25 itens) (α Cronbach – 0,89). Material e Métodos: Obtivemos uma amostra de conveniência de inscritos em centros de emprego que foi aleatoriamente dividida em duas subamostras (amostra 1 = 5127 e amostra 2 = 5134). Aplicámos a análise de componentes principais na amostra 1. Com a amostra 2 procedeu-se à análise fatorial confirmatória usando o método da máxima verosimilhança. Usámos a análise multigrupo para a comparação do modelo fatorial entre os géneros e a situação profissional. Efetuámos a análise convergente e divergente através da análise de correlação de Pearson. Resultados: A análise de componentes principais extraiu um fator com uma variância explicada de 53,97%. A análise fatorial confirmatória comprovou a unidimensionalidade da escala. Confirmámos a invariância entre géneros e situação profissional. A escala de resiliência Connor-Davidson de 10 itens correlacionou-se positivamente com as medidas da escala SF-36 e negativamente com a escala GHQ-12. Discussão: A análise exploratória e confirmatória corroborou a unidimensionalidade e boas propriedades psicométricas, semelhantes à escala original de 10 itens. Conclusão: Trata-se do primeiro estudo de validação desta escala na população portuguesa (Portugal), de acordo com a pesquisa efetuada. Os seus resultados são muito satisfatórios, recomendando-se o seu uso na população portuguesa.
