"Pregnancy and life span
The idea of a trade-off between reproduction and longevity is called the disposable soma theory (43
, 44
). This theory predicts that, for females, young age at first birth and high parity will be associated with a shorter postreproductive life span because of high physical demand, thereby shortening their lives (45
).
Few large-scale analyses on different human populations have been able to show the beneficial effect of pregnancy on maternal life span. A historical data set from the British aristocracy (46
) demonstrated that female longevity was positively correlated with age at first childbirth and that women who had their last child late in life lived longer. Historical Sami women who produced their last offspring at an advanced age lived longest, whereas age at first pregnancy and fertility were not found to be correlated to female longevity (47
). Similar results were reported in a study using data from an Old Order Amish community in Pennsylvania, indicating that over a large range of parity values, 1 to 14 children, life span was associated positively with childbirth at an advanced age while having little or no association with parity (48
).
It seems that postreproductive life expectancy extension is coupled with late births, as reported in studies published in the last few years in which large historical demographic databases of Utah, England, and Wales populations and a French-Canadian cohort were analyzed (45
, 49
, 50
, 51
). The findings described in this review may explain the beneficial effect on longevity of pregnancy at advanced maternal age.
In conclusion, the data presented in this review highlight the novel concept that pregnancy has a beneficial effect on the mother and may help to overcome the negative effects of aging. This effect has been found in various maternal organs and is probably not due to a single common pathway but rather to specific mechanisms in different tissues."
