    Blood Lead Levels Among Pregnant Women: Historical Versus Contemporaneous Exposures
    (2012-11-01) Edwards, Sharon E; Miranda, Marie Lynn; Neelon, Brian Hugh; Paul, Christopher J; Swamy, Geeta Krishna
    Blood lead among pregnant women, even at modest levels, may impair offspring cognitive development. We examine whether blood lead levels (BLLs) result from current versus historic exposures, among a cohort of pregnant women. Cumulative logit models were used to characterize the relationship between maternal risk factors and higher BLLs. Maternal blood lead levels more likely result from lead remobilization from historic versus contemporaneous exposures. Even if all lead sources were abated immediately, women and their fetuses would experience lead exposure for decades. This work emphasizes the importance of addressing sources of environmental lead exposure in the United States and internationally.

    Using geographic information systems to characterize food environments around historically black colleges and universities: Implications for nutrition interventions.
    (Journal of American college health : J of ACH, 2020-06-22) Vilme, Helene; Paul, Christopher J; Duke, Naomi N; Campbell, Santiba D; Sauls, Derrick; Muiruri, Charles; Skinner, Asheley C; Bosworth, Hayden; Dokurugu, Yussif M; Fay, John P
    OBJECTIVE:To understand the distribution of healthy and unhealthy food stores near historically black colleges and universities (HBCUs). Participants and methods: Using ArcGIS Pro's network analysis tools and ReferenceUSA database, this study characterized the healthy (favorable) and unhealthy (unfavorable) retail food stores within a 5-mile radius, 15-min driving, and 15-min walking distance from each HBCU in North Carolina. Results: Most retail food stores within a 5-mile buffer radius of the 10 HBCUs in North Carolina were unfavorable. Within 15-min driving from each HBCU, 1082 stores (76.0%) were unfavorable food stores, while 332 (24.0%) were favorable. Additionally, there were four favorable and 35 unfavorable retail food stores within the 15-min walking distance of each HBCU. Conclusions: Favorable food retail stores around HBCUs in North Carolina are limited. Researchers, policy makers, and community stakeholders should work together to improve food environments surrounding HBCUs.
