With support from the National Institute for Environmental Health Sciences, University of Cincinnati researchers are launching a study of African-American women to determine whether childhood lead exposure has affected bone and muscle health as the women who will be studied have matured into their early-to-mid-30s.

The research project, which is part of the long-term Cincinnati Lead Study, will involve 120 women who were born in high-lead risk areas of Cincinnati between 1979 and 1984. Involving researchers from the University of Cincinnati (UC) College of Medicine, the UC Department of Environmental Health and the Cincinnati Children’s Hospital Medical Center, the Cincinnati Lead Study has followed 376 people and is the longest-running study of lead exposure effects on health and development in the world.

Dr. Amit Bhattacharya, a professor of environmental health at the University of Cincinnati, said the UC research team will be testing the hypothesis of whether any detrimental changes in bone and muscular structures associated with early lead exposure could predispose African-American women collectively to higher risk of early osteoporosis compared to individuals with no or reduced lead exposure.

The National Institute for Environmental Health Sciences (NIEHS), which is part of the National Institutes of Health, is funding the study with a grant totaling $2,354,927 over four years. Bhattacharya and Dr. Kim Dietrich, a UC environmental health professor, are leading the study.

Bhattacharya told Diverse that one expected outcome will be the early detection of risk among women in the study for bone disease, such as osteoporosis. That will be possible because the research team will be using a new technology developed by Bhattacharya and Dr. Nelson Watts called Bone Shock Absorbance (BSA). The BSA technology uses sensors to measure how energy from strikes to certain bones is absorbed and dissipated through the musculoskeletal system.

“The most important thing about this project in terms of significance is that our patented new technology, which does not use radiation, will help identify those subjects who are at risk of developing bone fragility, meaning those who would be at risk of having an osteoporotic fracture later in life,” Bhattacharya said.

“So having that knowledge in advance—who is at risk of having a potential fracture due to osteoporosis early in life—there may be some lifestyle intervention that can be proposed or recommended by health care providers, such as nutritional changes or physical activity,” he noted.

Bhattacharya explained that African-Americans have not typically been evaluated for bone health issues by the medical research community and he suggested the new study may encourage further inquiry into African-American bone health. “African-Americans, traditionally and unfortunately, were not evaluated for bone health concerns because the old traditional research data has shown that Blacks do not have problems with bone health. But, in reality, newer information says they do have comparable, or similar, bone health issues as Caucasians,” he noted.

As blood lead concentrations in the U.S. population have fallen since the banning of lead as a gasoline additive, lead sequestered in bone continues to be a source of internal exposure for millions of people, according to the UC researchers. Research has shown this is especially true for African-Americans and other urban-based minorities exposed to moderate to high levels of lead during their childhood years “by virtue of lead residues from paint in older and sometimes poorly maintained” homes.

“African-Americans are historically more likely to live in inner cities than Whites, and lower-income, inner-city children remain particularly vulnerable to lead exposure,” Dietrich said in a statement.

Bhattacharya and Dietrich say the new study coincides with growing concerns Americans are having with the aging of the U.S. population. That focus on aging means that it’s timely for the Cincinnati Lead Study to assess the risks childhood lead exposure will have for older adults.
