    Exposure to contaminants in Great Lakes fish has been linked to impaired neuropsychological functioning in children, but neurological function of exposed adults has not been evaluated.

    This report describes a cross-sectional analysis of the effects of PCB/DDE exposure from contaminated fish on fine motor function in older adults.

    The subjects were 50-90-year-old Michigan residents who were members of a previously established study cohort.

    Fisheaters ate 24 lbs or more of sport-caught Lake Michigan fish/year at the time they were originally recruited in 1980-1982.

    Age-and sex-matched non-fisheaters ate 6 or fewer lbs/year.

    Outcome measures were scores on the Static Motor Steadiness Test (SMST) and Grooved Pegboard Test (GPT).

    PCB/DDE exposure was determined through serum analyses performed at the time of recruitment into the present study in 1993-1995.

    Because of the high correlation between serum PCB and DDE levels in this sample (Spearman r=0.64, P<0.0001), the effects of the two contaminants were assessed jointly using a single derived exposure variable : Low=both PCB and DDE at or below the medians of their respective distributions, intermediate=PCB and/or DDE in the third quartile, and high=PCB and/or DDE in the upper quartile.

    In unadjusted analyses, high exposure to PCBs/DDE was associated with significantly poorer performance on the GPT (P=0.03). (...)
