Maternal anxiety and fetal behavior at 15 weeks' gestation

Objective To analyze the relationship between maternal anxiety and fetal behavior at 15 weeks' gestation. Methods Twenty women in two groups were studied: 10 women underwent amniocentesis and 10 controls did not. Maternal anxiety was evaluated using the State Trait Anxiety Inventory. questionnaire. Maternal plasma catecholamines (noradrenaline, adrenaline, dopamine) and maternal serum adrenocorticotropic hormone, cortisol, glucose, insulin, triiodothyronine, thyroxine and thyroid-stimulating hormone were measured. Catecholamines were also measured in the amniotic fluid of women undergoing amniocentesis. Compiled actograms of 40-min observations were done using ultrasonography. Results Maternal state-anxiety was significantly increased in the amniocentesis group. Except for fetal hiccups (r = 0.49, P = 0.03) there was no significant correlation between maternal anxiety and any of the other studied fetal movements. Maternal glucose was significantly correlated with hiccups (r = - 0.59, P = 0.01), isolated leg movements (r = - 0.52, P = 0.03), startles (r = - 0.47, P = 0.04) and the total of the studied movements (r = - 0.47, P = 0.04). Amniotic fluid catecholamines were significantly correlated with band-face contact (r = 0.71, P = 0.02 for adrenaline), startles (r = 0.75, P = 0.01 for noradrenaline and r = 0.64, P = 0.04 for dopamine) and general movements (r = 0.89, P = 0.001 for noradrenaline). Conclusions This study does not support a relationship between maternal anxiety and fetal behavior in early pregnancy. Maternal glucose and plasma catecholamines could be related to fetal movements at 15 weeks' gestation. Copyright (C) 2003 ISUOG. Published by John Wiley Sons, Ltd.
