Pre-pandemic psychiatric disorders, disease specific polygenic scores, and alcohol consumption patterns during the COVID-19 pandemic
Background
Pre-pandemic psychiatric disorders have been associated with elevated alcohol consumption during the COVID-19 pandemic, raising concerns about associated morbidity and mortality; however, insight into the mechanisms is lacking.
Methods
In this prospective cohort study with multiple follow-ups of 27,208 participants from the Danish Blood Donor Study, the potential genetic influence on the associations of pre-pandemic alcohol use disorders (AUD) and major depressive disorder (MDD) with pandemic alcohol consumption patterns was assessed in Poisson regression models, using polygenic scores (PGS). Information on pre-pandemic psychiatric disorders was obtained from Danish national health registers, while information on alcohol consumption was obtained through questionnaires.
Results
Adjustment for PGSs did not impact the association of pre-pandemic AUD with alcohol consumption patterns during the COVID-19 pandemic at any time points (e.g., unadjusted [B = 0.68; 95 %CI: 0.52; 0.84] vs. adjusted for AUD PGS [B = 0.66; 95 %CI: 0.50; 0.82]. However, higher AUD PGSs were associated with higher alcohol consumption among individuals without pre-pandemic AUD. Pre-pandemic MDD was unrelated to alcohol consumption patterns during the COVID-19 pandemic in all analyses.
Conclusion
Genetic liability to AUD was associated with increased alcohol consumption during the COVID-19 pandemic but only among individuals without pre-pandemic AUD.
期刊介绍:
Founded in 1961 to report on the latest work in psychiatry and cognate disciplines, the Journal of Psychiatric Research is dedicated to innovative and timely studies of four important areas of research:
(1) clinical studies of all disciplines relating to psychiatric illness, as well as normal human behaviour, including biochemical, physiological, genetic, environmental, social, psychological and epidemiological factors;
(2) basic studies pertaining to psychiatry in such fields as neuropsychopharmacology, neuroendocrinology, electrophysiology, genetics, experimental psychology and epidemiology;
(3) the growing application of clinical laboratory techniques in psychiatry, including imagery and spectroscopy of the brain, molecular biology and computer sciences;
