The Sleep After Breast Cancer (ABC) Study - Examining Sleep Changes and Biomarkers Among Breast Cancer Patients

The Sleep After Breast Cancer (ABC) Study - Examining Sleep Changes and Biomarkers Among Breast Cancer Patients

This study is being done to learn more about breast cancer patients' experiences with sleep changes during cancer treatment, identify possible reasons for poor sleep quality, and to find out how stress, social support, and living environment affect sleep.

PRIMARY OBJECTIVES:

I. Characterize longitudinal trends in sleep among BC patients from treatment through survivorship, overall and by race, ethnicity, and underserved communities (rural, urban, Appalachian) using actigraphy-assessed sleep duration (Aim 1a), and self-reported sleep quality (Aim 1b).

II. Identify risk factors (sociodemographic, clinical treatment, social support, built environment) associated with sleep duration and sleep quality over time.

III. Assess how sleep duration and quality affect premature biological aging, stress, and inflammatory markers in BC patients from treatment to survivorship, overall and by race, ethnicity, and community.

OUTLINE: This is an observational study.

Patients undergo collection of cheek swab, saliva, and hair samples, wear a wrist sleep tracking device, and complete surveys throughout the study. Additionally, patients have their medical records reviewed on study.
