Unearthing Toxic Beauty
Skin lightening products (SLPs) are widely used among communities of color and often contain toxic chemicals that pose serious health risks. Despite regulations, these products remain accessible in the United States through deceptive labeling and illegal sales, which might contribute to unequal availability of and access to products containing harmful chemicals. This study uses a novel spatial sampling approach to audit retailers in Northern Manh…
Chemicals of concern in select packaged hair relaxers available on the Kenyan market
Background: There is an emerging interest in the investigation of hair relaxers as important sources of exposure to chemicals of concern (CoCs) and their associated adverse health effects. We focused on documentation of CoCs by examining labels of selected relaxers currently available on the market in Nakuru and Embu Counties, Kenya and measured the pH profiles to ensure compliance with Kenya Bureau of Standards. Methods: We enrolled 746 women ag…
Associations Between Discrimination and Substance Use Among Transgender Women of Color in New York City
Introduction: Transgender women of color (TWOC) face elevated rates of substance use, driven in part by intersecting systems of discrimination and structural inequities. Previous research has highlighted the connection between discrimination and substance use, but few studies have explored this relationship among TWOC. This study examines cross-sectional and longitudinal associations between perceived discrimination and substance use among TWOC i…
Feasibility and Acceptability of Assessing Personal Care Product Use and Exposure to Endocrine-Disrupting Chemicals Among Black and Hispanic Breast Cancer Survivors
This pilot study explored the feasibility and acceptability of utilizing silicone wristbands to assess exposure to endocrine-disrupting chemicals (EDCs) among 25 Black and Hispanic breast cancer survivors recruited in Washington, DC, and Hackensack, NJ. Over half of participants (58%) were diagnosed with Stage I breast cancer and the mean age was 58 ± 9 years. Most of the 24 survey respondents (95.83%) reported that the wristband did not interfer…
Validating the Black Identity, Hair Product Use, and Breast Cancer Scale (BHBS) Among Black Breast Cancer Survivors
The BHBS is a valid tool to measure identity, attitudes, and behaviors about product use and breast cancer risk among survivors. Hair is a significant cultural identity expression, and the health effects of styling products should be considered in future interventions
Hair Dye and Relaxer Use among Cisgender Women in Embu and Nakuru Counties, Kenya
Despite widespread use of hair products globally, little is known about the prevalence and patterns of use in populations outside the United States. As some hair products contain endocrine-disrupting chemicals (EDCs) and EDCs have been linked to breast cancer, which is increasing globally, in this study, we addressed key knowledge gaps about hair product use and practices, and perceptions of use among women in two counties in Kenya. Using communi…
Predictors of Phthalate Metabolites Exposure among Healthy Pregnant Women in the United States, 2010–2015
Phthalate use and the concentrations of their metabolites in humans vary by geographic region, race, ethnicity, sex, product use and other factors. Exposure during pregnancy may be associated with detrimental reproductive and developmental outcomes. No studies have evaluated the predictors of exposure to a wide range of phthalate metabolites in a large, diverse population. We examined the determinants of phthalate metabolites in a cohort of racia…
Beauty Beware
(1) Background: Widespread personal care product (PCP) use can expose individuals to endocrine-disrupting chemicals (EDCs) associated with adverse health outcomes. This study investigated the association between harm perceptions and hair-product-purchasing behaviors in adults enrolled in a cross-sectional study. (2) Methods: Respondents rated their agreement with five PCP-related harm statements using a five-point Likert scale. Multivariable-adju…

Oncotype DX Test Receipt among Latina/Hispanic Women with Early Invasive Breast Cancer in New Jersey
Oncotype DX ® (ODX) is a valid test of breast cancer (BC) recurrence risk and chemotherapy benefit. The purpose of this study was to examine prevalence of and factors associated with receipt of ODX testing among eligible Latinas/Hispanics diagnosed with BC. Sociodemographic and tumor data of BC cases diagnosed between 2008 and 2017 among Latina/Hispanic women ( n = 5777) were from the New Jersey State Cancer Registry (NJSCR). Eligibility for ODX …
Pathways between objective and perceived neighborhood factors among Black breast cancer survivors
Objective neighborhood disorder might be related to perceived disorder directly and indirectly through perceptions of neighborhood social cohesion
Heavy is the Head That Wears the Crown
Racial disparities in breast cancer are well-documented, and Black women assume a disproportionate burden of breast cancer mortality. Black women also commonly use hair products containing endocrine disrupting chemicals (EDCs) more often at an increased rate, as compared to other racial/ethnic groups. Emerging findings have reported the use of hair and other personal care products containing EDCs may contribute to breast cancer risk. While some s…
Visual cues of the built environment and perceived stress among a cohort of black breast cancer survivors
We investigated relationships between independently observed, visual cues of residential environments and subsequent participant-reported stress within a population-based cohort of Black breast cancer survivors (n = 476). Greater visual cues of engagement - presence of team sports, yard decorations, outdoor seating - (compared to less engagement) was marginally associated with lower perceived stress in univariate models, but attenuated towards nu…
