Association between cognitive activity and cognitive function in older Hispanics.
There is limited research on the association between participation in cognitively stimulating activity and cognitive function in older Hispanics. The main purpose of the present study was to explore whether frequency of cognitive activity and its association with cognitive function in Hispanics is comparable to that of non-Hispanics. In a multiethnic cohort of 1571 non-demented older adults, we assessed past and current cognitive activity, availability of cognitive resources in the home in childhood and middle age, and five domains of cognitive function. The measures of cognitive activity and cognitive resources had adequate reliability and validity in our subset of Hispanic participants (n = 81). Hispanics reported lower levels of education, lower frequency of cognitive activity and less cognitive resources than non-Hispanic White (n = 1102) and non-Hispanic Black (n = 388) participants. Despite these differences the strength of the association between cognitive activity and cognitive function was comparable across ethnic groups. Because Hispanics have lower frequency of cognitive activity, the benefit of cognitive activity to late life cognitive function may be potentially larger in this segment of the population. Thus, interventions aimed at increasing frequency of participation in cognitively stimulating activity may offer a potential target to reduce cognitive impairment in Hispanics.
