Item type: Ítem , A nationwide cross-sectional study of workers’ mental health during the COVID-19 pandemic: Impact of changes in working conditions, financial hardships, psychological detachment from work and work-family interface(Universidad Siglo 21, 2022-03-18) Trógolo, Mario Alberto; Moretti, Luciana Sofía; Medrano Leonardo Adrián MedranoBackground The COVID-19 disease has changed people’s work and income. While recent evidence has documented the adverse impact of these changes on mental health outcomes, most research is focused on frontline healthcare workers and the reported association between income loss and mental health comes from high-income countries. In this study we examine the impact of changes in working conditions and income loss related to the COVID-19 lockdown on workers’ mental health in Argentina. We also explore the role of psychological detachment from work and work-family interaction in mental health. Methods A total of 1049 participants aged between 18 and 65 who were working before the national lockdown in March 2020 were recruited using a national random telephone survey. Work conditions included: working at the usual workplace during the pandemic, working from home with flexible or fixed schedules, and being unemployed or unable to work due to the pandemic. Measures of financial hardship included income loss and self-reported financial problems related to the outbreak. Work-family interface included measures of work-family conflict (WFC) and family-work conflict (FWC). Mental health outcomes included burnout, life satisfaction, anxiety and depressive symptoms. Data were collected in October 2020. Results Home-based telework under fixed schedules and unemployment impact negatively on mental health. Income loss and particularly self-reported financial problems were also associated with deterioration of mental health. More than half of the participants reported financial problems, and those who became unemployed during the pandemic experienced more often financial problems. Finally, psychological detachment from work positively influenced mental health; WFC and FWC were found to negatively impact on mental health. Conclusions Countries’ policies should focus on supporting workers facing economic hardships and unemployment to ameliorate the COVID-19’ negative impact on mental health. Organisations can protect employees’ mental health by actively encouraging psychological detachment from work and by help managing work-family interface. Longitudinal studies are needed to more thoroughly assess the long-term impact of the COVID-19-related changes in work and economic turndown on mental health issues.Item type: Ítem , Pan-American migraine prevalence: Findings from the Americas’ migraine observatory study (AMIGOS)(Universidad Siglo 21, 2026-03-06) Lisicki, Marco; Muñoz-Cerón, Joe; Machado Sarmento, Elder; Polycarpo Ribeiro, Adriana; de Assis Dantas, Ana Carolina; Lara do Prado, Leandro; de Nunes, Ana Karolina; Oliveira, Arao B; Moraes Marcelo; Ramos de Andrade, Juliana; Vélez-Jiménez, Karina; Rodriguez-Leyva, Ildefonso; Espinoza Giacomozzi, Alex Rodrigo; Bancalari, Ernesto; Juliet, Raúl; Schubaroff, Pablo; Peres, Mario F. P.Introduction: Analyzing the epidemiology of headache disorders is fundamental for understanding their behaviour anddesigning effective public health strategies. Epidemiologic studies conducted in individual countries often lack consistentmethodologies, limiting broader interpretation. The Americas’ Migraine Observatory Study (AMIGOS) is a Pan-Americanepidemiological study designed to evaluate the burden and access to treatment of migraine and other headache disordersacross the Americas. Here, we present data on migraine prevalence and disability.Objectives: To describe and compare the prevalence and burden of migraine in the Americas at a specific time pointusing a unified sampling methodology. Additionally, to identify regional variations and potential factors contributing todifferences in prevalence, providing a foundation for targeted public health strategies.Materials and Methods: Data were collected online or via telephone from a sample representative of the demographicand social characteristics of each country, with a confidence level of 98% and a margin of error of 5%. We conducted bothqualitative and quantitative research on key aspects of headaches among 16,202 individuals in 19 countries from Canadato Chile. Migraine diagnosis was made based on the ICHD-3 criteria.Results: The overall prevalence of migraine was 9.7% (13.2% among females, 6.5% among males). The highest prevalence wasobserved in Brazil (13.8%), Canada (13.2%), and the United States (12.7%), while the lowest prevalence was found in Bolivia (5.5%),Paraguay (7.1%), and Argentina (7.3%). Participants typically experienced 4 headache days per month, and chronic migraine prevalencewas estimated at 1.3%. The migraine burden, as measured by Years Lived with Disability (YLDs), was highest in the United States.Item type: Ítem , ¿Alguien o algo?
