† reference category * significantly different from estimate for reference category (p < 0.05 adjusted for number of comparisons) ‡ significantly different from estimate for males (p < 0.05) Notes: The limit of detection for blood lead was 0.02072 μg/dL or 0.001 μmol/L. The limit of detection for urinary bisphenol A was 0.2 μg/L. Source: 2007 to 2009 Canadian Health Measures Survey.
