Physical and mental health impact of the COVID-19 pandemic at first year in a Spanish adult cohort.

The COVID-19 pandemic and the political and health measures have profoundly affected the health of our populations. However, very few studies have been published assessing its impact using a prospective cohort. The aim of this study is to describe the impact on physical and mental health due to the COVID-19 pandemic in the general population in Spain, and according to COVID-19 clinical status, during the first year of the pandemic. A longitudinal cohort study with two online surveys were performed on a representative sample of the adult Spanish population before (N = 2005, October/November 2019) and during the pandemic (N = 1357, November/December 2020). We assessed disability using the World Health Organisation Disability Assessment Schedule (WHODAS), major depressive episode (MDE) and suicidal thoughts and behaviours (STB), using an adapted version of the Composite International Diagnostic Interview (CIDI 3.0); generalised anxiety disorder (GAD) using the GAD-7 scale; post-traumatic stress disorder (PTSD) symptoms using the PTSD checklist for DSM-5 (PCL-5). For physical health, there was a statistically significant loss of weight (mean/SD) (T0, 73.22/15.56 vs. T1, 71.21/11.94), less use of tobacco (T0, 11.4% vs. T1, 9.0%) and decreased disability (mean/SD) (T0, 21.52/9.22 vs. T1, 19.03/7.32). For mental health, there was a significant increase in MDE (T0, 6.5% vs. T1, 8.8%) and in the prevalence of GAD (T0, 13.7% vs. T1, 17.7%). The prevalence of STB (T0, 15.1% vs. T1, 7.1%) significantly decreased. Individuals who declared they had been diagnosed with COVID-19 (3.6%) showed a worsening in physical health and an increase in mental health problems and PTSD symptoms. Although suicide risk during the first year of the pandemic was significantly less, many suicide risk factors increased: such as the incidence and persistence of MDE and GAD, the presence of PTSD symptoms in those diagnosed with COVID-19, and a worsening in self-assessed health status. We expect an increase in STB in the population in the long-term. Future research should gather information about the long-term impact of the pandemic.

Socio-economic and psychological impact of COVID-19 pandemic in a Spanish cohort BIOVAL-D-COVID-19 study protocol / Impacto socioeconómico y psicológico de la pandemia de COVID-19 en una cohorte española protocolo del estudio BIOVAL-D-COVID-19

Objective: SARS-CoV-2 outbreak has a negative psychological impact among general population. Data comparing mental health status before and during the outbreak is needed. The BIOVAL-D-COVID-19 study assess the socio-economic and psychological impact of the COVID-19 pandemic and lockdown in a representative sample of non-institutionalized Spanish adult population, and estimate the incidence of mental health disorders, including suicidal behaviours, and possible related factors. Method: Observational longitudinal study including two online surveys: baseline survey (T0) performed during 2019 and follow-up survey (T1) conducted 12-month later. The latter included nine sections: socio-demographic, health status, mental health, employment conditions and status, material deprivation, use of healthcare services, intimate partner violence and resilience. Four of the nine sections are administered in T0 and T1 assessments. Longitudinal data analyses will estimate adjusted incidence rates of mental health disorders using Poisson regression models. Risk and protective factors will be analysed through multiple logistic regression models. (AU)

Objetivo: el estudio BIOVAL-D-COVID-19 evaluará el impacto socioeconómico y psicológico de la pandemia de COVID-19 y del confinamiento en una muestra representativa de población española adulta no institucionalizada, y estimará la incidencia de trastornos de salud mental, incluida la conducta suicida, y los posibles factores relacionados. Métodos: estudio longitudinal que incluye dos encuestas online: la encuesta basal (T0) realizada durante 2019 y la encuesta de seguimiento (T1) realizada 12 meses después. Esta última tiene nueve secciones: variables sociodemográficas, estado de salud general, salud mental, condiciones laborales y estatus laboral, privación material, uso de servicios de salud, violencia de pareja y resiliencia. Cuatro de las nueve secciones se administran en ambas encuestas (T0 y T1). Se utilizarán modelos de regresión de Poisson para el análisis longitudinal de las tasas de incidencia ajustadas de trastornos de salud mental. Los factores de riesgo y de protección se analizarán mediante modelos de regresión logística múltiple. (AU)
