Preface
   This is one in a series of reports examining the prevalence of Adverse Childhood Experiences
   (ACEs) in the Welsh adult population and their impact on health and well-being across the life
   course. The series will include reports on:

   ■■ The prevalence of Adverse Childhood Experiences and their association with health-harming
      behaviours in the Welsh adult population.

   ■■ The impact of Adverse Childhood Experiences on chronic ill health, use of health and social care
      services and premature mortality in Welsh adults.

   ■■ The impact of Adverse Childhood Experiences on mental well-being in Welsh adults.

   Over 2,000 adults aged 18-69 years participated         representative of the general population in Wales.

   information on their exposure to ACEs before            residence using an established questionnaire

   as adults. The study achieved a compliance rate         US Centers for Disease Control and Prevention and
   of 49.1% and the sample was designed to be              based on work by Felitti et al (1998) [1].

 Foreword
Adverse Childhood Experiences (ACEs) are an
increasing international concern. There is a
growing body of evidence that our experiences
during childhood can affect health throughout
the life course. Children who experience stressful
and poor quality childhoods are more likely to
adopt health-harming behaviours during
adolescence which can themselves
lead to mental health illnesses and
diseases such as cancer, heart disease
and diabetes later in life. Adverse
Childhood Experiences are not just a
concern for health. Experiencing ACEs
means individuals are more likely to
perform poorly in school, more likely to
be involved in crime and ultimately less
likely to be a productive member of society.

                        Executive Summary
                              An increasing body of research identifies the long-term harms
                               that can result from chronic stress on individuals during
                                childhood. Such stress arises from the abuse and neglect of
                                  children but also from growing up in households where
                                   children are routinely exposed to issues such as domestic
                                    violence or individuals with alcohol and other substance

                      Experiences (ACEs) in Wales
     ACEs are stressful experiences occurring during childhood that directly harm a child
        (e.g. sexual or physical abuse) or affect the environment in which they live
                     (e.g. growing up in a house with domestic violence).

        ACEs increase individuals’ risks of
      developing health-harming behaviours
           Compared with people with no ACEs, those with 4+ ACEs are:
  4 times more likely to be a high-risk drinker
  6 times more likely to have had or caused unintended teenage pregnancy
  6 times more likely to smoke e-cigarettes or tobacco
  6 times more likely to have had sex under the age of 16 years
 11 times more likely to have smoked cannabis
 14 times more likely to have been a victim of violence over the last 12 months
 15 times more likely to have committed violence against another person in the last 12 months
 16 times more likely to have used crack cocaine or heroin
 20 times more likely to have been incarcerated at any point in their lifetime

    Prevalence of Adverse Childhood Experiences in Wales
Just under half of all individuals surveyed had experienced at least one ACE before the
age of 18 years (46.5%). 13.6% had experienced four or more ACEs. The prevalence of
individual ACEs ranged from 4.6% of respondents reporting living with a drug-using
household member during their childhood, to 22.8% experiencing more than one
episode of verbal abuse as a child2 (see Figure 2 and Appendix 2 Table i).

4   The specific act of divorce or parental separation can be either harmful or beneficial to the child but in ACE studies divorce or parental separation is
    often used as a marker of substantive, often long-term conflict between parents.

    Breaking the ACE Cycle in Wales
Results from the Welsh ACE survey identify both the potential harms across the
life course resulting from avoidable stress and adversity in childhood and the huge
potential health gains possible if childhood experiences are improved. As these analyses
have shown, the benefits of preventing ACEs are not limited to health, but also impact
on violent crime and social issues such as teenage pregnancy.

    Box 1: ACEs and Resilience
    Within the context of ACEs, resilience can be considered as an individual’s ability to avoid harmful
    behavioural and physiological changes in response to chronic stress. Such individuals have the skills and
    often have received the support necessary to adapt successfully to the stress, trauma and other forms of
    chronic adversity [17]. Alongside the ACE questionnaire, resilience questionnaires have also been developed
    to identify whether children have assets available to them (e.g. a loving parent/carer) that may help reduce
    the acute and long-term impacts of ACEs on their health and behaviour. Health visitors may use resilience
    tools to identify the supportive factors that need to be delivered through targeted services in order to
    improve health outcomes for individuals.

Wales. However despite significant investment, the
overall impact of these programmes on preventing
ACEs is often unclear. In order to effectively reduce
ACEs in Wales and improve individuals’ life course
prospects, a number of issues should be addressed.
Firstly, improved awareness is needed of the
importance of early life experiences on the long-term
health, social and economic prospects of children.
Information should be available to a wide range
of professionals (health, education, social, criminal
justice and others) on ACEs, their consequences
and how they can be prevented. Information should
also be disseminated to the public and especially
those planning or having children. All parents and
their children in Wales should already have access to
support services – especially in early years. However,
a better understanding is needed of specifically what
support every individual should and ultimately does
receive. Support must conform to established and
emerging evidence of what works in the prevention
of ACEs and the successful development of resilience
in children. Finally, some families (often but not
exclusively in deprived communities) require enhanced

Questionnaire
The study used an established survey tool developed by the US Center for Disease Control and Prevention to
measure the prevalence of ACEs14. Alongside basic demographics, such as age, sex, ethnicity and marital status,
data was collected on the following categories outlined in Table i.

The interview utilised methods of Computer Assisted Personal Interviewing (CAPI), and also Computer Assisted
Self Interviewing (CASI) for the more sensitive sections of the questionnaire. Respondents were also given the
option to complete the survey on paper. On completion of interview, individuals were issued with a thank-you
leaflet which included information on the survey, contact details for help-lines in Wales and contact details for
the research team if they required further information regarding the study.

Response rate and compliance
A total of 14,893 households were visited during the study period. Contact was made with 6,293 households,
of which 4,127 included individuals conforming to the inclusion criteria. Thus, of the known eligible households,
2,099 (50.86%) opted out of completing the survey, leaving a compliance rate of 49.14% (n=2028).

Sample characteristics
Table ii illustrates the sample demographics of the survey participants in comparison to the Welsh population15.
Overall, 49.8% of respondents were male and 50.2% were female, which did not differ significantly from the
Welsh population estimates in mid-2013 for gender (p=0.901). However, the final ACE sample had a slight but
significant over-representation of individuals aged 18 to 29 years and 60-69 years, and an under-representation
of those aged 30-59 years. There was also an over-representation of individuals within the least deprived
deprivation quintile in Wales and significant differences in ethnicity.

15 For ethnicity, data was obtained from the 2011 Census: http://www.ons.gov.uk/ons/rel/census/2011-census/key-statistics-for-local-authorities-
   in-england-and-wales/rpt-ethnicity.html . All other population estimates were obtained from the Office for National Statistics’ mid-2013

Calculation of Health-Harming Behaviours (HHBs)

in Table iii.
