Children starved of warmth and affection suffer lifelong health problems

The effects of childhood abuse and lack of parental affection can last a lifetime, taking a toll both emotionally and physically, reveals a new study.

A new UCLA-led study for the first time examines the effects of abuse and lack of parental affection across the body's entire regulatory system.

The study, published online by the Proceedings of the National Academy of Sciences, found a strong biological link for how negative early life experiences affect physical health and can even lead to cardiovascular disease.

However, it's not all bad news. 'Our findings suggest that there may be a way to reduce the impact abuse has, at least in terms of physical health," said Judith E. Carroll, a research scientist at the Cousins Center for Psychoneuroimmunology at UCLA, and the study's lead author.
'If the child has love from parental figures they may be more protected from the impact of abuse on adult biological risk for health problems than those who don't have that loving adult in their life.'
The researchers studied 756 adults who had participated in a study called Coronary Artery Risk Development in Young Adults (CARDIA).

They measured 18 biological markers of health risk, such as blood pressure, heart rate, stress hormone, cholesterol, waist circumference, inflammation, and blood sugar regulation, and analysed if they were at higher biological risk for disease.

To determine the study subjects' childhood stress the researchers used a self-report scale called the Risky Families Questionnaire.

They found a significant link between reports of childhood abuse and multisystem health risks, but those who reported higher amounts of parental warmth and affection in their childhood had lower multisystem health risks.

The researchers also found a significant interaction of abuse and warmth, so that individuals reporting low levels of love and affection and high levels of abuse in childhood had the highest multisystem risk in adulthood.

The authors note that the findings used information provided by the participants, so there may be some recall bias.

Also, the analysis may not have captured other factors affecting regulatory systems, such as poor nutrition or environmental pollution.

But the findings suggest that parental warmth and affection protect one against the harmful effects of toxic childhood stress.

Also, the lingering effects of childhood abuse can be linked to age-related diseases such as cardiovascular disease. Among other things, this could have an effect on long-term health care costs.
'It is our hope that this will encourage public policy support for early interventions,' Carroll said.

'If we intervene early in risky families and at places that provide care for children by educating and training parents, teachers, and other caregivers in how to provide a loving and nurturing environment, we may also improve the long term health trajectories of those kids.'
