Women after a simple prenatal intervention were half as likely to be depressed eight years later compared to women who received standard care. This is according to a new study from the University of California, San Francisco, published in the Journal of Consulting and Clinical Psychology.
It is one of the first studies to look at outcomes so far into the future.
What the scientists studied
The pregnant women in the study participated in group wellness classes that met weekly for eight weeks.
Led by Elissa Epel, PhD, a UCSF professor of psychiatry and her team, groups of eight to ten pregnant women met for two hours a week. They performed mindfulness-based stress reduction exercises. Special attention was paid to nutrition, breathing and physical activity. The women also had two telephone sessions and a group postpartum “booster” session with their babies.
Wellness care is not just for white women
According to senior study author Niki Bush, historically, most studies of prenatal depression have included mostly white women, but not this one.
In the study, 162 women were assigned to either the intervention group or the standard care group. The women’s depression symptoms were assessed using the Patient Health Questionnaire (PHQ-9) before, after, and at 1, 2, 3-4, 5, 6, and 8 years.
How wellness care affected women
Both groups of women had similar symptoms of depression before exercise. Only 12% of those who were part of the wellness class reported moderate or severe depressive symptoms after eight years, compared to 25% of women who received standard care.
Next steps for the scientists
The researchers are now collecting additional data to better understand how the intervention had such a long-term effect. Potential mechanisms include long-term changes in the ability to cope with stress, healthy eating and exercise.
A previous study on the same group of women found that the intervention also reduced the short-term risk of depression and diabetes and supported healthier stress responses in their children.
