Adult Children's Condition Index (image) Max-Planck-Gesellschaft Caption Higher maternal age harms only seemingly: adult children's index of diagnosed conditions seems to rise steeply with maternal age (turquoise curve). Adjusted for the real effects, the mother's education and the age at which the child lost the mother, the curve becomes much flatter (blue line). For maternal age of 35 years and greater, the increase is no longer statistically significant (dashed part of black line).
