These comprised health-care providers (Tate et al, 2013), medication (Bassett et al, 2007;Tate et al, 2013;Collis and Waterfield, 2015), receiving medical treatment (Bassett et al, 2007;Sato-Komata et al, 2015), going for regular medical check-ups (Sato-Komata et al, 2015;Chen et al, 2019) and receiving informal care (Bassett et al, 2007).
