Highly complex work across adulthood might predict higher cognition in late-life. This study examined the associations between the complexity of household work in a woman's primary lifetime and her late-life cognitive function. We used baseline data of 767 women aged 69-82 years from SONIC in Japan. We adopted the complexity of work with data, people, and things to complexity of household work. Comprehensive cognitive function was assessed using the Montreal Cognitive Assessment. Consistent with results of complexity of work, an association was found between more complex household work with data and higher cognitive performance in older women. We also found that high complexity of both occupational and household work with data independently related to better cognitive function. These findings suggest that engagement in not only occupation but also household work in middle age have the potential to play a positive role to maintain cognition in late-life.
