| Objective: To investigate magnetic-field exposure and other risk factors associated with cognitive function in military aged people.Methods: A cross section study in 273 military retired cadres were carried out. All of the subjects filled in the standard questionnaires, and the levels of serum FBG, TC, TG, HDL, LDL were determined. By cognitive impairment group, Uni variate and multivariate analyses were conducted using Logistic regression model.Results: Univariate analysis showed smoking, the history of stroke and COPD were significantly different between normal and abnormal cognitive function groups, and the OR(95%CI) were 2.61 (1.16-5.88), 5.09 (2.05-12.68) and 2.74 (1.15-6.54) , respectively. After adjusted for age, gender and other factors, smoking, drinking, history of stroke and higher SBP and TC level were danger to cognitive function impairment, and the OR(95%CI) were 3.87 (1.40-10.68) , 4.07 (1.12-14.79) , 4.79 (1.56-14.68) , 1.04 (1.01-1.07) and 2.04 (1.11-3.74) , respectively. There was not significant relationship between magnetic-field exposure and cognitive function impairment, and the OR(95%CI) was 0.60 (0.24-1.51) .Conclusions: Smoking, drinking , high blood pressure and TC level may he the risk factors of cognitive function impairment.
