Ilango SD, et al. - Using linear mixed-effects regression models, researchers explored the connection of pregnancy history with trajectories of cognitive function in older women. Participants were 1,025 females (mean age = 73.1 ± 9.6 y) registered in the Rancho Bernardo Study who attended a clinic visit between 1988 and 1992, when history of pregnancy (ever pregnant, number of pregnancies, ages at first and last pregnancy) was recorded and cognitive function was evaluated with a battery of four tests repeated up to 7 times through 2016. The findings do not indicate any long-term clinically significant impact of pregnancy history on age-related cognitive function change. These reassuring findings suggest childbearing decisions and timing in older age will not affect cognitive function.
