The age effect, observed by Shevlin and colleagues, was confirmed for anxiety/depression (Adj OR = 0.96, CI = 0.95–0.97, p < 0.001), and traumatic stress (Adj OR = 0.97, CI = 0.96–0.98, p < 0.001), showing more moderate cases in younger participants. A gender difference was observed only in COVID-19 anxiety, with men less anxious than women about the new virus (Adj OR = 0.33, CI = −0.03–0.69, p < 0.001). No differences were observed between regions.
