First-Time Mom: Higher Depression Risk
Postpartum Depression Risk Is Highest in Baby's First Month
Dec. 5, 2006 -- First-time mothers have a higher risk for postpartum depression than other new moms, and their risk is greatest during their first three months of parenthood, a Danish study shows.
Compared with women who had given birth 11 to 12 months earlier, first-time mothers were found to have seven times the risk of psychiatric-related hospital admissions during the first 10 to 19 days of their baby's life.
The increase in risk remained throughout the first three months after childbirth, regardless of the age of the mother. Postpartum risk appeared to decrease with subsequent pregnancies, researcher Trine Munk-Olsen, MSc, tells WebMD.
Munk-Olsen and colleagues analyzed the medical histories of close to 2.4 million Danish citizens registered in a national health database.
Their findings are published in the Dec. 6 issue of The Journal of the American Medical Association.
"This study confirms that the timing of postpartum risk is very precise," she says. "The first month after giving birth is definitely the most dangerous time for postpartum mental disorders, but the risk remains for several months after."
Dads Weren't Depressed
Between 1973 and 2005, just over 630,000 women and 547,000 men in Denmark became parents for the first time. During the same period a total of 1,171 women ad 658 men were admitted to psychiatric hospitals during their first year of parenthood.
Several smaller studies have suggested that postpartum depression occurs among new dads, as well as new moms. But the Danish findings do not support this.
Within the first three month after becoming parents, roughly 1 in 1,000 women and 1 in 3,000 men in the Danish population studied experienced severe mental disorders that required hospitalization or outpatient psychiatric treatment.
"Unlike motherhood, fatherhood was not associated with any increased risk of hospital admission or outpatient [psychiatric] contact," the researchers note.
Routine Screening Needed
As many as one in seven new mothers in the U.S. experience some degree of postpartum depression, according to government figures.
Though earlier studies also suggested that first-time moms have the highest risk for mental health problems, the Danish population study is by far the largest to examine the issue and the first large-scale postpartum depression trial to be conducted in two decades.
