Babies of WWI Dead Had Shorter Lives

French children born between 1914 and 1916 whose fathers were killed or severely injured during World War I lost approximately one year of adult life expectancy, according to a new study.

The study, presented at the 55th annual meeting of the European Society for Paediatric Endocrinology, contributes to the understanding of the long-term effects of maternal psychological stress on children, according to the researchers.

Some hypotheses state that much of our susceptibility to diseases in adulthood may stem from very early life experiences. Of particular interest are negative early life experiences, usually called early life adversities (ELAs).

These encompass both nutritional and psychological stresses, the researchers said, noting the effects of early life exposure to famine have been extensively studied through other natural experiments, such as the Dutch famine of 1944 or the Chinese famine of 1959.

However, a lack of adequate historical data has made it difficult to assess the potential long-term consequences of psychological ELAs, the researchers noted.

For the new study, a team of French researchers from Inserm used newly accessible historical databases to identify more than 4,000 children born between 1914 and 1916 whose fathers were either killed or severely injured during World War I. Both of these groups are considered to have suffered ELAs.

Of the children who had lost their father, the researchers also determined whether the death occurred before or after their birth.

Each individual was matched with a “control” of the same sex, age of mother, and date and district of birth.

The researchers discovered that all of those who experienced ELA suffered an increased mortality in adulthood, losing an average of one year of adult life expectancy compared to controls.

The decrease in adult life expectancy was greater for those whose father had been killed while their mother was pregnant — a median of 2.2 years shorter than controls, according to the study’s findings.

“The next step in the study will be to determine the cause of death for those having suffered ELA. This will shed light on the mechanisms involved,” said Nicolas Todd, lead researcher of the Inserm team from Hôpital du Kremlin-Bicêtre in France.

“We know that deregulation of the stress response is commonly found on animal models of ELAs, so it will be interesting to see if any evidence of this can be seen in the causes of death in the French cohort. It may give us further insight into the long-term effects of ELA.”
