Age shows inconsistent patterns across the nine different behavior change outcomes. Older persons are less likely to have adapted their work situation (OR = 0.79; 95%CI = 0.75–0.82), to self-quarantine (OR = 0.91; 95%CI = 0.85–0.97) or to use disinfectants (OR = 0.92; 95%CI = 0.88–0.96). Probability of behavior change increased with older age for keeping distance to other people (OR = 1.13; 95%CI = 1.07–1.18) and reducing personal meetings and contacts (OR = 1.15; 95%CI = 1.09–1.21). No clear associations were found related to the measures avoiding (busy) places, increased hand hygiene, and wearing face masks.
