Washington: Adverse childhood experiences have been found to increase the risk of lung cancer, particularly premature death from lung cancer.
The study suggests that children can be faced with a terrible burden of stressors.
These stressors are associated with harmful behaviours, such as smoking, that may lead the development of diseases like lung cancer and perhaps death at younger ages.
The research team suggests that reducing the burden of adverse childhood experiences should therefore be considered in health and social programs as a means of primary prevention of lung cancer and other smoking-related diseases.
David Brown and Robert Anda, from the Centers for Disease Control and Prevention, Atlanta, USA, worked with a team of researchers to study the effects of abuse (emotional, physical, sexual), witnessing domestic violence, parental separation, or growing up in a household where people were mentally ill, substance abusers, or sent to prison.
He said, "Adverse childhood experiences were associated with an increased risk of lung cancer, particularly premature death from lung cancer.
Although smoking behaviours, including early smoking initiation and heavy smoking, account for the greater part of this risk, other mechanisms or pathophysiologic pathways may be involved".
According to Brown, "Compared to those who claimed no childhood trauma, people who experienced six or more traumas were about three times more likely to have lung cancer, identified either through hospitalization records or mortality records.
“Of the people who developed, or died of, lung cancer, those with six or more adverse events in childhood were roughly 13 years younger at presentation than those with none.
“People who had experienced more adverse events in childhood showed more smoking behaviors,” he added.
