目的了解超高压输变电线路产生的工频电磁场是否对居住居民的健康产生影响。方法按居住地距高压输变电线路垂直距离远近分为观察组和对照组,以相同的问卷对两组居民的一般生活状况、健康状况及与健康相关的行为进行面对面地询问调查。结果两组居民一般生活状况及与健康相关的行为无统计学差异;两组人群个体神经精神状态调查中自述头痛和易疲劳的比例则有统计学差异。结论高压输变电线路产生的工频电磁场对居住居民的健康的主观影响多于客观影响。
Objective To understand whether the power frequency electromagnetic field generated by EHV transmission lines has an impact on the health of residents. The method was divided into observation group and control group according to the distance of residence from the vertical distance of high-voltage power transmission lines. The same questionnaire was used to inquire about the general living conditions, health status and health-related behaviors of two groups of residents face to face. Results There were no significant differences in general living conditions and health-related behaviors between the two groups. There was a significant difference in the proportion of self-reported headache and fatigue in the investigation of neuropsychiatric status between the two groups. Conclusion The subjective impact of power frequency electromagnetic fields generated by HV transmission lines on the health of residents is more than objective.
