Living in racially and ethnically segregated neighborhoods may increase the risk of breast cancer. We examined associations between neighborhood racial and ethnic composition typology and incident primary invasive breast cancer risk in a population-based sample of 102,615 African American/Black, Japanese American, Native Hawaiian, Latino, and White females residing in California and Hawaii from the Multiethnic Cohort (MEC) study between 1993-2019. Hazard ratios (HRs) and 95% confidence intervals (CI) were estimated using multivariable Cox proportional hazards regression.

- Recent studies indicate that exposure to fine particulate matter (PM) is linked to an increased risk of breast cancer, particularly among diverse populations, but data is limited.
- In a large study of 58,358 women from the Multiethnic Cohort in California, researchers found a significant association between PM and breast cancer incidence, noting variations based on family history but not on race or hormone receptor status.
- The study emphasizes the need for both personal and population-level strategies to reduce PM exposure in order to help prevent breast cancer, especially in areas where incidence rates are rising.
Article Synopsis
- Allostatic load (AL) is a measure of stress in the body and may affect cancer survivorship, particularly among women with breast cancer.
- The study involved 2,553 participants and found that women who lived in low socioeconomic neighborhoods or areas with high traffic, crime, crowding, or fast-food restaurants had higher AL scores.
- The research suggests that improving neighborhood conditions could potentially enhance health outcomes for breast cancer survivors, highlighting the need for further studies on neighborhood stressors and their physiological effects.
Association between Airport Ultrafine Particles and Lung Cancer Risk: The Multiethnic Cohort Study.
Cancer Epidemiol Biomarkers Prev
May 2024
Background: Ultrafine particles (UFP) are unregulated air pollutants abundant in aviation exhaust. Emerging evidence suggests that UFPs may impact lung health due to their high surface area-to-mass ratio and deep penetration into airways. This study aimed to assess long-term exposure to airport-related UFPs and lung cancer incidence in a multiethnic population in Los Angeles County.

Here we characterized alcohol outlet density in Los Angeles County, CA, and Hawaii and assessed the association of alcohol outlet density with self-reported alcohol intake in the Multiethnic Cohort.
Method: Participants ( = 178,977) had their addresses geocoded at cohort entry (1993-1996) and appended to block group-level alcohol outlet densities (on- and off-premises).
