Anxiety or Nervousness Disturbs the Progress of Birth Based on Human Behavioral Evolutionary Biology.

In general, anxiety or nervousness in pregnant women increases the risk of dystocia. Pregnant women are easily susceptible to anxiousness or nervousness. To support a safe and healthy birthing process, childbirth educators, other health-care professionals, and pregnant women require an in-depth understanding about the disruptive effects of anxiety or nervousness on birth progress. Anxiety and nervousness are difficult to quantify and may be influenced by culture. Therefore, reports comparing anxiety or nervousness with dystocia must include various biases. It is difficult to find this issue by medical research. Here, we discuss links between anxiety or nervousness and disturbance in the progress of birth based on the adaptive standpoint of human behavioral evolutionary biology. © Copyright 2019 Lamaze International.
