Which is more important, hereditary factors or psychological environment factors, in the etiology of anorexia nervosa? The question is studied by considering 7 cases of anorexia nervosa in monozygotic twins of the authors' own practice. In 5 of 7 cases, only 1 of a set of twins was found to be suffering from anorexia nervosa. On the other hand, in 2 of 7 cases, both twins were diagnosed as having anorexia nervosa. Even in the concordant cases studied by the authors, however, the quality or degree of anorexia nervosa in each case was different. Therefore, even given the existence of concordant cases, without inquiring precisely into the quality or degree of anorexia nervosa, it is not possible to conclude that hereditary factors play a determining role in the etiology of anorexia nervosa.
在神经性厌食症的病因中,遗传因素和心理环境因素哪个更重要?作者通过研究自己经手的7对同卵双胞胎中的神经性厌食症病例来探讨这个问题。在7例中的5例里,一组双胞胎中只有1人患有神经性厌食症。另一方面,在7例中的2例里,双胞胎两人都被诊断患有神经性厌食症。然而,即使在作者研究的一致病例中,每例神经性厌食症的性质或程度也有所不同。因此,即使存在一致病例,如果不精确探究神经性厌食症的性质或程度,就不可能得出遗传因素在神经性厌食症病因中起决定性作用的结论。
