Prevalence and determinants of probable depression and anxiety during the COVID-19 pandemic in seven countries:Longitudinal evidence from the European COvid Survey (ECOS)

BACKGROUND: Our aim was to present data on the prevalence of probable depression and anxiety and to determine their correlates during the COVID-19 pandemic in seven European countries using a longitudinal approach. METHODS: Longitudinal data (wave 4 in November 2020: n = 7,115; wave 5 in January 2021: n = 7,068; wave 6 in April 2021: n = 7,204) were taken from the European COvid Survey (ECOS), a representative sample of non-institutionalized inhabitants from Germany, United Kingdom, Denmark, Netherlands, France, Portugal and Italy aged 18+. Probable depression and anxiety were quantified using the established and validated PHQ-4 (2-item depression scale, PHQ-2 / 2-item anxiety scale, GAD-2). RESULTS: In wave 4 (wave 5; wave 6), 26.6% (25.5%; 23.8%) of all respondents had probable depression and 25.7% (23.6%; 22.1%) had probable anxiety. Prevalence rates for probable depression and probable anxiety differed significantly between countries. Among all countries and waves, particularly high prevalence rates were found among individuals aged 18 to 29 years. Longitudinal analysis showed that the likelihood of probable depression was positively associated with increasing age, great income difficulties and lower health-related quality of life. The likelihood of probable anxiety was positively associated with income difficulties, and lower health-related quality of life. LIMITATIONS: Screening tool was used to quantify the outcomes. CONCLUSION: The magnitude of probable depression and anxiety during the COVID-19 pandemic in European countries was highlighted. Moreover, determining the factors associated with probable depression or anxiety (e.g., income difficulties, worse health-related quality of life) may assist in identifying individuals at increased risk

First Search for Axion-Like Particles in a Storage Ring Using a Polarized Deuteron Beam

Based on the notion that the local dark-matter field of axions or axion-like particles (ALPs) in our Galaxy induces oscillating couplings to the spins of nucleons and nuclei (via the electric dipole moment of the latter and/or the paramagnetic axion-wind effect), we performed the first experiment to search for ALPs using a storage ring. For that purpose, we used an in-plane polarized deuteron beam stored at the Cooler Synchrotron COSY, scanning momenta near 970 MeV/c. This entailed a scan of the spin precession frequency. At resonance between the spin precession frequency of deuterons and the ALP-induced EDM oscillation frequency there will be an accumulation of the polarization component out of the ring plane. Since the axion frequency is unknown, the momentum of the beam and consequently the spin precession frequency were ramped to search for a vertical polarization change that would occur when the resonance is crossed. At COSY, four beam bunches with different polarization directions were used to make sure that no resonance was missed because of the unknown relative phase between the polarization precession and the axion/ALP field. A frequency window of 1.5-kHz width around the spin precession frequency of 121 kHz was scanned. We describe the experimental procedure and a test of the methodology with the help of a radiofrequency Wien filter located on the COSY ring. No ALP resonance was observed. As a consequence an upper limit of the oscillating EDM component of the deuteron as well as its axion coupling constants are provided.Comment: 25 pages, 24 figures, 7 tables, 67 reference
