Unhappy childhood linked to heart risk in later life

Emotional behaviour in childhood may be linked with heart disease in middle age, especially in women, research suggests.

A study found being prone to distress at the age of seven was associated with a significantly higher risk of cardiovascular disease in later life.

Conversely children who were better at paying attention and staying focused had reduced heart risk when older.

The US researchers said more work was needed to understand the link.

Their study looked at 377 adults who had taken part in research as children. At seven they had undergone several tests to look at emotional behaviour.

They compared the results from this with a commonly used risk score for cardiovascular disease of participants now in their early 40s.

After controlling for other factors which might influence heart disease risk, they found that high levels of distress at age seven were associated with a 31% increased risk of cardiovascular disease in middle-aged women.

For men with high levels of distress in childhood - which included being easily frustrated and quick to anger - the increased risk of cardiovascular disease was 17%.

For 40-year-olds who had been prone to distress as a child, the chances of having a heart attack or stroke in the next 10 years increased from 3.2% to 4.2% for women and 7.3 to 8.5% for men.
