Adult survivors of childhood abuse are consistently less likely to follow United States Preventive Services Task Force cancer screening guidelines, with shortfalls most pronounced in cervical and breast screening according to a study published in PLOS Global Public Health.
A recent study published in PLOS Global Public Health reveals that adult survivors of childhood abuse show lower adherence to cancer screening recommendations established by the US Preventive Services Task Force (USPSTF). The analysis, which drew data from the Centers for Disease Control and Prevention’s 2020 Behavioral Risk Factor Surveillance System, shows that these disparities persist across multiple socioeconomic and health care-access strata, highlighting complex systemic challenges in preventive medicine.
Data From the 2020 Behavioral Risk Factor Surveillance System
The study reviewed findings from a nationally representative phone survey of United States adults conducted annually by the Centers for Disease Control and Prevention. Within the 2020 dataset, 123,169 respondents answered questions concerning physical, sexual, or emotional abuse experienced during childhood. According to the research, 43.7% of these respondents reported experiencing some form of childhood abuse. Women accounted for 52.3% of the surveyed cohort, and 62.7% of respondents identified as White.
The survey data highlighted notable demographic and health distinctions between respondents with a history of childhood adversity and those without. Individuals who reported childhood abuse tended to be younger, with 30.7% falling into the 18 to 34 age bracket compared with 24.5% of respondents who reported no abuse. Furthermore, abuse survivors were more likely to report a household income of less than $75,000 (57.8% versus 52.9%) and more likely to be uninsured (10.5% versus 7.9%). They also reported poorer health more frequently at 19.7% versus 14.3%, cited cost barriers to care at 17.4% versus 8.7%, and were less likely to have a personal doctor at 73.4% versus 77.0%.
Screening Adherence Rates Across Colorectal, Cervical, and Breast Cancers
When researchers evaluated adherence to USPSTF guidelines, they looked at eligible pools for three distinct cancer screening types. Overall, 58,390 respondents were eligible for colorectal cancer screening, 27,368 women were eligible for cervical cancer screening, and 39,986 women were eligible for breast cancer screening. Across all three categories, individuals with a history of childhood abuse demonstrated lower compliance rates than those without such a history.
For colorectal cancer screening, adherence stood at 72.4% among individuals without an abuse history compared to 71.9% among abuse survivors. For cervical cancer screening, adherence was 83.9% for those without an abuse history versus 81.6% for survivors. The most significant gap appeared in breast cancer screening, where adherence reached 73.0% for respondents with no abuse history but dropped to 67.0% for those with a history of childhood trauma.
These trends held in survey-weighted multivariable models. Childhood abuse remained associated with lower screening adherence, showing an adjusted incidence rate ratio of 0.97 with a 95% confidence interval of 0.94 to 1.00 for colorectal cancer, an aIRR of 0.97 with a 95% confidence interval of 0.94 to 0.99 for cervical cancer, and an aIRR of 0.96 with a 95% confidence interval of 0.93 to 0.99 for breast cancer.
Socioeconomic Factors and Insurance Coverage as Predictors
The research identified insurance coverage as the strongest predictor of screening adherence across fully adjusted, survey-weighted models. Study authors noted that screening shortfalls were particularly pronounced regarding breast screening among uninsured adults. While higher income and the possession of a college degree were associated with modestly higher adherence, and patients of color showed higher adherence than their White counterparts, traditional protective markers showed unexpected patterns.
Factors typically linked to a protective health effect—such as education, employment, and marriage—did not mitigate the negative impacts of child abuse. In fact, employment demonstrated a negative correlation with screening adherence in the findings.
The researchers found that screening shortfalls were most consistent for cervical and breast screening across multiple socioeconomic and health care-access strata and were particularly pronounced among breast screening among uninsured adults. They suggested these findings underscore the importance of reducing structural barriers and expanding access to preventive care, alongside trauma-informed approaches, to improve cancer screening uptake among populations affected by childhood adversity.
Implications for Future Public Health Interventions
The study authors emphasize that their findings should be interpreted as associations rather than causal effects. Nevertheless, the data point to potentially modifiable structural and access-related factors that can assist health officials in identifying groups at risk for under-screening.
By pinpointing these vulnerable populations, public health practitioners can better inform future targeted interventions and prospective studies designed to improve overall cancer screening uptake among adults affected by childhood adversity. The research underscores that improving participation rates will likely require a combination of expanded health care access, reduced structural financial barriers, and the integration of trauma-informed clinical approaches.
