The SWAN Multi-Pollutant Study (MPS) was initiated in 2016 to examine health effects of multiple environmental chemical exposures, including perfluoroalkyl and polyfluoroalkyl substances (PFAS), polychlorinated biphenyls (PCBs), organochlorine pesticides, polybrominated diphenyl ethers (PBDEs), metals, phenols, phthalates, and organophosphate pesticide among midlife women. Funded through two R01 grants by the National Institute of Environmental Health and Sciences (NIEHS), the SWAN MPS specifically investigates 1) obesity, type-2 diabetes and related metabolic endpoints (R01 ES026578); and 2) reproductive health including sex steroid hormones, age at menopause and ovarian aging (R01 ES026964).

- IN THE NEWS: Findings from SWAN Multi-Pollutant Study featured in “‘Forever chemicals’ up type 2 diabetes risk in midlife White women” with lead author and former Center Doctoral Student Mia Q. Peng
“Overall, our study has added some evidence to support the potential diabetogenic effects of phthalates, but it also highlights that much is still unknown about the metabolic effects of these chemicals. The apparent racial/ethnic differences in the associations between phthalates and incident diabetes should be investigated in future studies.”
Additional authors include Center Co-Director Carrie Karvonen-Gutierrez, Center Affiliate Faculty William Herman and Center Core Faculty Sung Kyun Park.

- IN THE NEWS: “Air pollution tips the scale for obesity in women” in Michigan News, with comments from Center Core Faculty Xin Wang, PhD, MPH
Women in their late 40s and early 50s exposed long-term to air pollution—specifically, higher levels of fine particles, nitrogen dioxide and ozone—saw increases in their body size and composition measures, said Xin Wang, epidemiology research investigator at the U-M School of Public Health and the study’s first author.

- IN THE NEWS: “‘Forever chemicals’ linked to high blood pressure in women” in the Washington Post, with comments from Center Postdoctoral Research Fellow Ning Ding, PhD, MPH
“Women seem to be particularly vulnerable when exposed to these chemicals,” said Ning Ding, research fellow in epidemiology, whose research found a link between PFAS (per- and polyfluoroalkyl substances) and high blood pressure in middle-aged women — adding to the long list of health risks associated with the man-made pollutants.

- WEBINAR: “Endocrine Disrupting Chemicals and Maternal Reproductive Health Impacts”; discussion with Center Postdoctoral Research Fellow Ning Ding, PhD, MPH, Julia Varshavsky, PhD, MPH, and Sverre Wikström, MD, PhD
Menopause marks the cessation of ovarian function, and its timing has physiologic impacts beyond the reproductive system, affecting women’s overall health. PFAS may play an important role in the process of reproductive aging, but the research is limited. Dr. Ning Ding investigated the impact of these chemicals on ovarian aging using data from the Study of Women’s Health Across the Nation (SWAN) as part of her dissertation work. Dr. Ding will present data on women’s exposure to PFAS and their associations with menopausal timing. Her research findings suggest that PFAS exposure may cause earlier natural menopause and accelerated ovarian aging.

“These numbers are striking. If children are getting served this every day, the cumulative effects could be substantial,” said Sung Kyun Park, associate professor of epidemiology and environmental health sciences, commenting on a congressional report that found high levels of toxic metals in several top baby food brands.

- IN THE NEWS: “PFAS exposure may lead to early menopause in women”; interview with Center Postdoctoral Research Fellow Ning Ding and Core Faculty Sung Kyun Park, ScD, MPH
“PFAS are everywhere. Once they enter the body, they don’t break down and build up over time,” said lead author Ning Ding , who conducted the study as a doctoral candidate at U-M’s School of Public Health and is now a postdoctoral researcher at U-M. “Because of their persistence in humans and potentially detrimental effects on ovarian function, it is important to raise awareness of this issue and reduce exposure to these chemicals.”
