A number of epidemiologic studies indicate an association between depression and proximity to high-voltage transmission lines. These studies have been criticized, however, for using surrogate measures of electromagnetic fields and unstandardized measures of depression. In an effort to overcome these limitations, the authors administered the Center for Epidemiological Studies Depression scale (CES-D) in 1992 to 152 women in Orange County, California, who lived either adjacent to a transmission line or one block away. The results indicated that the average magnetic field level is 4.86 mG at the front door of homes adjacent to transmission lines and 0.68 mG at the front door of homes one block away. There was no significant difference in CES-D scores between the groups when demographic variables were controlled for. The homogeneity of the study population may limit the generalizability of findings.
多项流行病学研究表明，抑郁症与靠近高压输电线路之间存在关联。然而，这些研究因使用电磁场的替代测量方法以及抑郁症的非标准化测量方法而受到批评。为了克服这些局限性，作者于1992年对加利福尼亚州奥兰治县的152名女性进行了流行病学研究中心抑郁量表（CES-D）测试，这些女性要么居住在输电线路附近，要么住在相隔一个街区的地方。结果表明，靠近输电线路的房屋前门处的平均磁场水平为4.86毫高斯，相隔一个街区的房屋前门处为0.68毫高斯。在控制了人口统计学变量后，两组之间的CES-D得分没有显著差异。研究人群的同质性可能会限制研究结果的普遍性。
