ABSTRACT = {This study investigates whether restricted participation in productive 
activity is associated with cognitive health in Korea. Furthermore, given the 
enormous socioeconomic disparities between aging and gender differences in 
employment, we also examine whether these associations vary by gender and age.
Data from the Korean Longitudinal Study of Ageing (KLoSA) from 2006 to 2016 
was used and 9,942 subjects were included at baseline in 2006. To analyze the 
association between restricted economic activity due to health condition and 
cognitive function, generalized estimating equation (GEE) model and chi-square 
test were used. Of the 9,942 individuals at baseline in 2006, the odds ratio (OR) of 
cognitive decline in those in the “very probable” of restricted economic activity 
was 2.58 times higher (<i>p</i>-value: < 0.0001) compared with “not at all” of restricted 
economic activity. In a subgroup analysis, ≤ 64 years and ≥ 65 years groups 
presented similar results. OR of cognitive decline in “very probable” of restricted 
economic activity was 2.50 times higher (<i>p</i>-value: < 0.0001) compared with “not 
at all” of restricted economic activity in both groups, respectively. For male and 
female, OR of cognitive decline in “very probable” of restricted economic activity 
was 2.77 times higher (<i>p</i>-value: < 0.0001) and 2.40 times higher (<i>p</i>-value: <
0.0001) compared with “not at all” of restricted economic activity, respectively. 
Our findings highlight association between restriction in economic activity and 
cognitive function among middle aged and elderly population in Korea. Given the 
benefits of economic activity, efforts should be made to improve health condition 
and reduce barriers to participate in economic activity.},
