Gender Differences in the Association between Adverse Childhood Experiences and Cancer.

OBJECTIVES

Adverse childhood experiences (ACEs) have been linked to a variety of diseases in adulthood, including cancer. However, current research has yet to determine if all abuse types are associated with cancer and if women are more adversely impacted by ACEs than men.

METHODS

Data from the 2011 Behavioral Risk Factor Surveillance System, a national survey of American adults 18 and older (N = 111,964) were analyzed. Logistic regression models were fit to estimate odds of ever being diagnosed with cancer after experiencing one or more of eight different ACEs, while adjusting for potential confounders. These analyses were then stratified by gender.

RESULTS

Among women, childhood experiences of physical abuse, sexual abuse, emotional abuse, living with someone who was mentally ill, living with a problem drinker, living with a drug user, and living in a household where adults treated each other violently were associated with higher odds of cancer. Among men, only emotional abuse was associated with higher odds of cancer.

CONCLUSIONS

Results suggest that ACEs increase risk of cancer later in life. However, this impact occurs mostly among women. This finding may be because women experience many ACEs at higher rates than men and because women, via sexual abuse, can be exposed to cancer-causing viruses.
