Abstract

Abstract

Objective To explore the impact of occupational aluminum exposure on delayed recall of workers. Methods A total of 435 workers in an aluminum factory in Shanxi province were evaluated for delayed recall using Montreal Cognitive Assessment Scale (MoCA) (Beijing Edition) and World Health Organization/University of California at Los Angeles Auditory Verbal Learning Test (AVLT). According to the blood aluminum concentration, the subjects were divided into low, medium and high exposure groups (T1, T2 and T3). Multiple logistic regression analysis was used to analyze the influencing factors of mild cognitive impairment (MCI) in aluminum exposed workers. Results All subjects are men. There were no significant differences in age, marriage, family monthly income, smoking and drinking among the three groups(P > 0.05). There were significant differences in working age and educational level among the three groups (P < 0.05). The delayed recall indexes in MoCA and AVLT of the three groups were statistically significant (P < 0.05). Multiple Logistic regression analysis showed that AVLT-LR score ≥ 6 was the protective factors of MCI (OR=0.860, 95% CI: 0.769-0.960); less education(OR=3.556, 95% CI: 1.589-7.957), more inserted words (OR=1.415, 95% CI: 1.070-1.871) and repeated words (OR=1.419, 95% CI: 1.043-1.931), no memory strategy (OR=2.124, 95% CI: 1.119-4.032) were the risk factors of MCI. Conclusions Occupational aluminum exposure can damage workers' delayed recall. The evaluation of MoCA and AVLT scales can determine the impact of delayed call and the combination of the two scales can better identify workers who may be prone to MCI.
