OBJECTIVETo intervene the health behavior of lead exposed workers by setting down and implementing a series of measures and evaluating the effects of these measures so that the occupational lead poisoning would be decreased.

METHODS105 lead exposed workers in a factory were chosen as subjects. Blood lead concentration and rate of cognition on relevant health knowledge were examined before and after intervened measures.

RESULTSThe cognition rate raised from 56.6% to 97.3% after training. Lead concentration in blood decreased by 17.7% (t = 4.10, P = 0.000) and delta-ALA in urine decreased by 23.9% (t = 4.248, P = 0.000) 12 months after intervention. The prevalence of occupational lead absorption and poisoning also decreased. The number of workers with blood lead content > 2.41 mumol/L was decreased from 6 to 3, and > 1.93 mumol/L from 14 to 10.

CONCLUSIONTo develope occupational health promotion, enhance health education and improve health behavior are the effective way to prevent from occupational lead poisoning.
