Increased stress levels were reported in fathers of premature babies during transitional Neonatal Intensive Care Unit (NICU) shifts to home. Men in the study were also found to be more stressed out than the mothers. The findings of this study are further discussed in Journal of Perinatal and Neonatal Nursing.
Fathers and mothers of these very low birth weight babies had high levels of the stress hormone cortisol in their saliva prior to being discharged. But the fathers experienced an increase in their stress levels as measured several times over the next 14 days at home while the mothers' stress levels stayed constant.
"Dad goes from a situation where the baby and mom are cared for by experts in the hospital to having to simultaneously care for his baby, partner and work. He is supposed to be the 'rock' for his partner but the stress can really set in," said lead author Dr. Craig Garfield, associate professor of pediatrics and of medical social sciences at Northwestern University Feinberg School of Medicine.
"One day of being stressed at home is not a big deal," said Garfield, who also is an attending pediatrician at Ann & Robert H. Lurie Children's Hospital of Chicago. "But if their levels are still high after two weeks, that's more concerning."
During the 14 days after arriving home, the fathers' cortisol levels steadily increased while the mothers' stress levels returned to "pretty much back to where they started," Garfield said.
Interestingly, the fathers' stress levels based on salivary test results were higher than they reported feeling in the survey. This could indicate that the fathers weren't in touch with how stressed they really were, Garfield said.
To help relieve fathers' stress and ease the transition, Garfield recommends parents place more emphasis on the dad becoming comfortable and gaining confidence with the baby while still in the NICU. Moms need to remember that dads need time to relax, too, Garfield said.
"Dads should be telling the mom to go take a walk, take a shower, see a friend," Garfield said. "But moms can also say, 'Why don't you go to the gym, see your friends, meet someone after work?' as ways to reduce some of the stress."
"Babies thrive when parents thrive, and if parents are stressed out, that can impact their parenting of the child, the relationship between the mom and dad and can alter infant attachment," he said. "This all is just much more pronounced with medically vulnerable babies leaving the NICU and going home with mom and dad."
While the study didn't examine stress levels in parents of full-term babies, Garfield said those parents still report feeling stress when returning home.
"While finally bringing a baby home is really wonderful, it can also be stressful because of sleep deprivation, the lack of control and having to respond constantly to the baby's needs," Garfield said.
