| Research Abstract |
Three studies were done to assess subjective stress by using objective indicators, i.e., QTc time and QT index on ECG: (1) To test links between QT-related parameters and the covariates possibly distorting them, the averaged RR and QT intervals were measured for 150 students. Sex, BMI and fat percentage were significantly related to the Bazett's QTc or Rautaharju's QT index. (2) To clarify if specific dietary behavior is related to liver injury, liver markers and dietary behaviors such as lunch menu were explored in 1809 workmen. Habitual instant noodle ingestion and ethanol intake were associated with elevated ALT. (3) To assess the impact of job and domestic stresses on autonomic nervous function, the links between the QT-related parameters and job/domestic stresses were analyzed in 1809 workmen. QT index was associated with drinking habit, and domestic stress. In conclusion, QT index appears to be a more useful indicator than the QTc; also, QT index may reflect domestic stress.
