Older individuals were more likely to have blood testing, as were individuals who were not employed or were retired (p < 0.05), an observation that is consistent with less flexible schedules and/or less concern about health among younger participants. Older participants also had higher rates of diabetes, but those were not found to be statistically associated with PCB levels. Although the ORs (95% CIs) are inter- nally valid as descriptors of associations in our study, they may not represent associations in Anniston as a whole because of our complex sampling design and exclusion of individuals with prediabetes. Conclusions This study demonstrates a statistically signifi- cant association of serum PCB levels with increased diabetes prevalence overall, espe- cially among women. Additionally, the most highly exposed individuals < 55 years of age had an elevated risk of diabetes. Ref Rencs ATSDR (Agency for Toxic Substances and Disease Registry). 2000.
