Incubator Care Reduces Depression Risk

Incubator Care Reduces Depression RiskBabies who receive incubator care after birth are two to three times less likely to suffer depression as adults.

The discovery surprised researchers as they had theorized mother-baby separation would result in heightened rates of clinical depression.

“In mammals, separation between mother and child after birth has always been considered a major stressor that can cause behavioral problems well into adulthood,” says coauthor Richard E. Tremblay a professor of psychology, pediatrics and psychiatry at the Université de Montréal.

“Our hypothesis was that mother-baby separation resulting from incubator care could heighten depression in adolescence or adulthood. Instead, we found that incubator care could decrease the risk of depression two-to-threefold by the age of 21.”

For this study, the research team studied a sub-sample of 1,212 children recruited from a longitudinal study launched in 1986. Children were recruited from Quebec kindergartens and facts on birth condition, obstetrical complications and incubator care were obtained through hospital medical records. Participants received psychiatric assessments when they were 15 and 21 years old. Researchers found that:

  • Of the 16.5 percent babies placed in incubators only 5 percent suffered major depression by age 21.
  • Among participants who were not placed in incubators, 9 percent developed depression, which is the average rate for general society.
  • Correlation between decreased depression and incubator care remained after factoring participant age, weight at birth, family adversity or maternal depression.

The research team also found that girls were three times less likely to experience depression by the age of 15 if they had received incubator care at birth.

“This difference was due to the fact that more girls experience depression than boys during adolescence and how boys suffer depression in later adolescent years,” says co author Frank Vitaro, a Université de Montréal professor and member of the Research Unit on Children’s Psychosocial Maladjustment.

Chain of biological and emotional factors

The research team found that direct and indirect stimuli — not just incubators per se — could decrease depression. For instance, incubators are controlled environments where body temperature, brain oxygenation, sound and light are adjusted to maximize neuronal development. What’s more, children who received incubator care as babies typically received more emotional support from their mothers throughout childhood because they were perceived as more vulnerable.

“Incubator care was not the sole factor that shielded participants from future depression,” says first author David Gourion, formerly of the Université de Montréal and Sainte Justine Hospital Research Center and now at psychiatrist at the Hôpital Sainte-Anne in Paris.

“We believe that incubator care is a trigger for a complex chain of biological and emotional factors that helped decrease depression.”

It is believed that this study is the first to examine the impact of incubator care on adult depression.

The study is published in the journal Psychiatry Research.
