Purpose: This study was conducted to clarify fatigue levels among people working in areas stricken by the Great East Japan Earthquake for consideration of nursing care toward the prevention of disasterrelated conditions.

Method: A survey of public servants working in quake-stricken areas was conducted to evaluate fatigue levels based on analysis of autonomic nerve function, sleep-wake rhythms, oxidative stress and the results of a questionnaire on perceived fatigue. The data were analyzed via t-testing and one-way analysis of variance. The study was conducted with the approval of the Research Ethics Committee.

Results: A total of 384 people (mean ± SD age: 40.3 ±10.1 years) agreed to take part in the study. In autonomic nerve function evaluation, 228 (62%) reported high levels of fatigue, and 88 (24%) reported a loss of balance in their LF (low-frequency) /HF (high-frequency) heart rate variability ratio, which showed a significant correlation to sleep efficiency (p = 0.014). With regard to age (under and over 40 years old), the LF/HF ratio and sleep time were significantly higher among the younger group (younger: p = 0.019; older 0.037). With regard to gender differences, time spent napping was significantly higher (p = 0.014) and diurnal activity was significantly lower (p < 0.001) among men.

Conclusion: All public servants working in stricken areas showed differences in awareness of fatigue levels and LF/HF ratios. Fatigue levels were particularly high among the group aged over 40 years old. The results indicate that preventive nursing care for fatigue is important among young staff working in stricken areas.
