Stress experienced in childhood may also influence our genes and be passed on to offspring. So unless the cycle is broken, it may continue from generation to generation.
When we talk about childhood adversity, it can cover specific experiences, such as neglect, abuse, or trauma. It can also cover unfavourable socioeconomic conditions such as poverty, low education or unemployment. In a recent study, we wanted to investigate two types of adversity.
We looked at the impact of serious conflict in the home – for example, tension, verbal arguments or physical violence. We also looked at severe financial difficulties experienced during childhood.
We analysed a large representative survey of European respondents and found that these two types of adversity significantly predicted various health problems in adulthood: physical, mental, and social. The impact was exacerbated if people had experienced both conflict and financial difficulties in childhood.
Experiencing severe financial strain in childhood can mean uncontrollable, chronic stress. This pattern of stress in a child’s body can become an obstacle to healthy development and effective learning later on. Financial strain can mean a child will lack basic necessities such as food, clothing and school books. And it means children are more likely to grow up in deprived and unsafe neighbourhoods.
Research shows this level of stress can inhibit a person’s ability to make decisions, which can have long-term implications. It also makes it less likely a person will achieve positive outcomes later in life.
In our study, we found that being exposed to financial strain or conflict during childhood is associated with heightened risk for a wide range of health and social problems in adulthood.
In terms of general health, we found that people who grow up in such environments are at increased risk of cancer, obesity or being hampered by physical health problems – such as cardiovascular diseases, breathing problems, physical pain, along with stomach or digestive problems.
We found that people who had difficult childhoods are more likely to binge drink, smoke, have a poor diet and tend to be less active – often engaging in sedentary behaviour.
Our results show a higher risk of depression, unhappiness, dissatisfaction with life, loneliness and feeling unsafe in one’s local area. We also found that childhood adversity puts people at increased risk of social isolation. They are less likely to interact with others and have general distrust towards other people – and those who get married are more likely to get a divorce.
All these health and social problems are likely to accumulate and intensify over time, ultimately reducing people’s quality of life, while creating multiple, complex, costly care needs.
Our data revealed that 25% of the survey respondents had experienced financial strain or conflict during their childhood. This means that one in four adults in Europe could be at increased risk of developing health problems due to these types of adversity.
Part of the solution needs to involve working with children and families affected by adversity. But there also needs to be more awareness and understanding about the damaging effects of conflict and financial strain in the home. This is important because ultimately this will affect children who grow up in these circumstances for the rest of their lives.
