Giving Birth Shortens a Woman’s Life Expectancy by Up to Two Years

A new study, executed by researchers at Northwestern University in Illinois, US, finds that giving birth shortens a woman’s life by up to two years. That means the more children a woman has, the shorter her lifespan may be.giving birth shortens women's life

For the study, the researchers examined 3,200 women aged from 20 to 22 years in the Philippines. They found that every birth has a damaging effect at the cellular level, having looked at two markers of cellular aging —telomere length and epigenetic age. These two factors may predict mortality.

Lead author Calen Ryan says: “Both [markers] appeared ‘older’ in women who had more pregnancies in their reproductive histories. Even after accounting for other factors that affect cellular aging, the number of pregnancies still came out on top.”

    I would like further research clarification of factors of cellular aging related to stress, or diminished stress, of family life such as carrying responsibility w/ adequate, or inadequate, support and resources.

      There is unfortunately no studies regarding the cellular aging in relation to the family life as every family is different, with different prevalence of stressful events and different perception of stress. However, several studies regarding the cellular aging and stress in general were conducted. It was found that chronic stress (especially during childhood or adolescence) may cause the cellular damage and accelerate the cellular aging by shortening the specific region of chromosomes known as telomere which is responsible for the cells’ life span. For example, in one research participated mothers which were taking care of their chronic ill children and mothers of healthy kids. Telomere regions appeared shorter in women who experienced child’s illness.
