Summary:
A new study found that adults who reported experiencing sexual
abuse by the age of 16 had a 2.6 times higher risk of dying in
middle age -- that is, between 45 and 58 -- than those who did
not report sexual abuse.



FULL STORY ========================================================================== Children who experience sexual or physical abuse or are neglected are
more likely to die prematurely as adults, according to a new study
analysing data from the 1950s to the present by researchers at UCL and
the University of Cambridge.


==========================================================================
The study, published in BMJ Open, found that adults who reported
experiencing sexual abuse by the age of 16 had a 2.6 times higher risk
of dying in middle age -- that is, between 45 and 58 -- than those who
did not report sexual abuse.

Adults who reported experiencing physical abuse by 16, meanwhile, had
a 1.7 times higher risk of premature death, while those who experienced
neglect - - assessed using questionnaire responses gathered from parents
and teachers of respondents during childhood -- had a 1.4 times higher
risk.

The researchers also looked at the link between early-life socioeconomic disadvantage and early death. They found that those who were disadvantaged
at birth (that is, those whose father's job was classed as unskilled
manual labour) had a 1.9 times higher risk of premature mortality than
other socioeconomic groups.

The study was based on data from 9,310 people born in 1958 who are part
of the 1958 National Child Development Study, a nationally representative
birth cohort study.

First author Dr Nina Rogers, who led the work while at UCL and is now
at the University of Cambridge, said: "Our work shows the long-lasting consequences that specific types of child abuse and neglect can have. The findings are especially important because these early-life adversities are
not uncommon, affecting millions of people in the UK."* The researchers examined socioeconomic and health-related factors that might explain why
people who were abused or neglected as children, or who were born at an economic disadvantage, were more likely to die in middle age. They found
that smoking appeared to be especially important in explaining mortality
among those who were physically abused or neglected, and among those
who were economically disadvantaged.



========================================================================== However, none of the examined factors, which ranged from mental health
to obesity to risky behaviour such as illegal drug-taking and problem
drinking, appeared to account for the higher likelihood of early death
for people who experienced sexual abuse as children.

Senior author Dr Snehal Pinto Pereira (UCL Surgery & Interventional
Science) said: "This study is the first to disentangle the independent associations between different kinds of child maltreatment and mortality
in adulthood.

Importantly, very few studies have considered the long-term implications
of experiencing neglect in childhood. I therefore think our finding
that children who are neglected have a 43% higher risk of dying early in adulthood, highlights a critical component of child maltreatment where knowledge of long- term outcomes is particularly sparse." The prevalence
of different early-life adversities among the cohort members included in
the study varied from 1.6% (sexual abuse) to 11% (psychological abuse),
with 10% classified as socioeconomically disadvantaged in early-life.

At seven and 11 years of age each cohort member's mother and teacher
answered questions from which the researchers were able to deduce if they showed signs of neglect. When cohort members were 45 years old, they were
asked questions about whether they had ever experienced sexual, physical
or psychological abuse or witnessed abuse of others in their family by
the age of 16 years. The researchers then followed the cohort members up
for 13 years and deaths were recorded during that time. Psychological
abuse and witnessing of abuse of others were not independently linked
to higher likelihood of early death.

The work was supported by the US National Institute on Aging (NIA) of
the National Institutes of Health, the UK Economic and Social Research
Council (ESRC), the Biotechnology and Biological Sciences Research Council (BBSRC) and the Medical Research Council (MRC).

* According to the Office for National Statistics, in 2019 the Crime
Survey for England and Wales estimated that one in five adults aged
18 to 74 years experienced at least one form of child abuse, whether psychological abuse, physical abuse, sexual abuse, or witnessing domestic violence or abuse, before the age of 16 years (8.5 million people).
