To understand the role of neighborhood disadvantage (ND) in cancer outcomes by examining various ND exposure domains, including socioeconomic deprivation, racial segregation, environmental pollutants, and built environment factors, over the life course.
Key Findings:
Geographic and racial/ethnic disparities in cancer outcomes exist but are not fully explained by current research, indicating a need for more comprehensive studies.
The neighborhood exposome includes socioeconomic deprivation, racial segregation, environmental pollutants, and built environment factors, all of which contribute to cancer risk.
Existing studies often fail to account for the temporality and cumulative nature of neighborhood exposures, which may lead to underestimations of their impact.
Interpretation:
Understanding neighborhood factors over time is crucial for establishing causality in cancer disparities and identifying modifiable risk factors that can inform public health interventions.
Limitations:
Few studies capture the dynamic nature of individual residential mobility and its impact on cancer risk, particularly in relation to specific socioeconomic variables.
Standard composite measures may overlook the relative importance of specific socioeconomic variables, such as income level and education, which can significantly influence cancer risk.
Conclusion:
This research aims to provide a comprehensive assessment of neighborhood disadvantage and its relationship with cancer incidence, potentially leading to targeted strategies for reducing disparities in cancer outcomes.
