Parental education tied to cognitive function in middle-aged and older adults

A new study published online in JAMA Network Open on May 30 suggests that parental education may play a crucial role in protecting cognitive health in middle-aged and older adults. The study, conducted by Shengyu Luo and colleagues from Sun Yat-Sen University in Guangzhou, China, focused on the association between maternal and paternal education levels and cognitive decline among participants from four different countries – China, the United States, England, and Mexico.

The analysis included a total of 36,065 participants from the four countries, with varying levels of parental education. The researchers found that higher levels of maternal and paternal education were associated with slower rates of cognitive decline over time. Specifically, maternal education at the upper secondary level or higher was linked to slower rates of cognitive decline in China, the United States, and England. In Mexico, only primary maternal education showed a significant association with slower cognitive decline.

Similarly, paternal education at the upper secondary level or higher was associated with slower cognitive decline in the Chinese, U.S., and English cohorts. In Mexico, primary paternal education was linked to slower cognitive decline. The study also found that the participants’ own education levels played a mediating role in the association between parental education and cognitive decline in all cohorts except Mexico.

The authors of the study emphasize the long-term impact of parental education on offspring’s cognitive health across different cultural and socioeconomic contexts. They suggest that improving educational attainment could help reduce intergenerational disparities in late-life cognitive health. The findings highlight the importance of investing in education not only for individual well-being but also for the cognitive health of future generations.

Overall, this study provides valuable insights into the role of parental education in shaping cognitive health outcomes in middle-aged and older adults. It underscores the importance of educational opportunities in promoting cognitive resilience and reducing cognitive decline in later life. Further research in this area could help identify effective strategies to improve educational outcomes and support cognitive health across generations.
