Thirty families with a newborn mongol baby were matched with thirty families with a normal baby. Both groups were followed for eighteen months to two years and interviewed six times. Few differences could be found in the mental or physical health of the two groups of parents, but marital breakdown or severe marital disharmony was found in nine of the mongol families and in none of the controls.
30个患有先天性愚型新生儿的家庭与30个拥有正常新生儿的家庭进行了匹配。两组家庭均被跟踪观察了18个月至2年，并接受了6次访谈。两组父母的身心健康几乎没有差异，但在患先天性愚型的家庭中有9个出现了婚姻破裂或严重的婚姻不和，而在对照组家庭中则未出现这种情况。
