“…In the research area of cancer, previous studies have also suggested that exposure to information about the role of exercise in cancer prevention could increase exercise motivation among university students (Courneya & Hellsten, 2001), general adults (Graham, Prapavessis, & Cameron, 2006), and adults with higher cancer risk (McGowan & Prapavessis, 2010). In the research area of dementia, although population-based studies have examined which and how many people expected physical activity to minimize dementia risk (Ayalon, 2013;Friedman et al, 2013;Low & Anstey, 2009;Smith, Ali, & Quach, 2014), it remains unclear whether the expectation about it is related to physical activity level. If the expectation for physical activity to minimize dementia risk influences physical activity engagement in older adults, it suggests that increasing expectation about this effect would promote physical activity among this population.…”
