All Stressed Out

Having a baby is usually considered a joyous event, but all those dead-of-night feedings, pushy in-laws and general jitters can make life miserable for any new mom. To make matters worse, some women experience serious post-natal depression, which leads to a vicious cycle of fatigue, fights and even more stress. This can be particularly distressing for family members caught in the crossfire – a stressed-out mama can turn from “sweet-and-nurturing” to “hellfire-and-brimstone” at the drop of a hat.

Thus for new parents-to-be the recent announcement by US researchers that “measuring levels of a hormone midway through pregnancy may predict a woman's risk of postnatal depression” should be welcome news. The study focused primarily on the relationship between post-natal depression, which usually “starts four to six weeks after giving birth” and “affects around 10 to 15 percent of mothers,” and “pCRH (placental corticotropin-releasing hormone)” – a type of hormone that produces cortisol, which the body produces in greater amounts during pregnancy to help mothers-to-be deal with stress.

Problems can arise when pCRH levels naturally “dip after birth,” a phenomenon which is theoretically more pronounced in women with higher levels, thus producing increased bouts of stress. You can read more about the study results hereand here, and if you’re a new dad-to-be, considered yourself forewarned.

Mothers, of course, aren’t the only ones who have to deal with stress – kids, especially middle-schoolers, are notorious for acting up and lashing out (once again, you can blame all the hormones). This has become such a problem in some Chinese schools (not to mention in the US where school shootings have become seemingly and tragically commonplace) that a middle school in Jinan has even taken the extreme measure of setting up an "emotion venting room" where “punching bags painted with the faces of the faculty and staff (including, more notably, the headmaster) were placed that “students could hit to vent their feelings of anger, resentment, frustration and depression.” The overall effectiveness of such a measure remains unclear, but news of this and other related incidents are a sure sign of increasingly desperate times.

another study links higher levels of CRH in pregnancy with 3.3 times higher rates of preterm labor and 3.6 times higher rates of intrauterine Fetal Growth Restriction

But the body does not produce cortisol "to deal with stress" --cortisol doesn't have a therapeutic effect as implied in the post above, it's simply a RESULT of feeling stress, a measurable hormone which is useful for measuring stress.

The stress response goes in stages: Cortico-tropin Releasing Factor travels to the Pituitary, then produces ACTH which travels to the adrenals, which produce Cortisol and then go on to communicate with a wide range of body systems...positively as a short term survival mechanism but if it's a chronic state it has a hugely negative effect on many systems (brain, immune, fat digestion).

For instance, babies' stress can be measured with a saliva swab and a measure of the cortisol there. Cortisol interferes and restricts neuronal growth and neurotransmitter activity...so stress is to be avoided in infants, especially very young infants.

Re: All Stressed Out

Risk factors for postpartum depression also are: Cesarean section & also anaesthetic drugs during delivery. So having a natural (drug free) birth is protective (there's tons of research, go on http://www.ncbi.nlm.nih.gov and type in your keywords and you'll get like a million).

Also, looking at large groups of postpartum women, breastfeeding is also HIGHLY protective against Postpartum depression. http://www.internationalbreastfeedingjournal.com/content/2/1/6

Certain B vitamins also are protective http://cat.inist.fr/?aModele=afficheN&cpsidt=18217921

And of course having loving relationships and a supportive environment for the new mom cannot be understated too.
