The field of epigenetics studies how environmental factors such as stress, diet, and toxic exposures can affect the expression of genes without changing the underlying DNA sequence. This research has shown that epigenetic changes can contribute to the development of psychological disorders such as anxiety, depression, and schizophrenia. Cultural influences (A) can certainly affect the prevalence and manifestation of psychological disorders, but they do not directly impact gene expression. The medical model (B) refers to the traditional approach to diagnosing and treating mental illness, and does not relate to gene-environment interactions. The stress of childbirth (D) can have an impact on maternal and infant health, but is not directly related to epigenetic changes or gene expression in the context of psychological disorders.
