title: [Factors related to subjective fatigue symptoms of adolescent girls].
abstract: OBJECTIVE
  To assess changes in subjective fatigue symptoms of adolescent girls over a 15-year period and investigate factors related to these symptoms.
  
  
  METHODS
  A total of 86 items on physical health (including subjective fatigue symptoms), dietary life, and daily living were investigated and five items on physical activity were measured for approximately 100 female first-year dietetic students at a junior college each October over the 15-year period from 1994 to 2008. A total of 1,547 students (mean age, 19.2 +/- 0.3 years) were studied. Subjects were first divided into two groups using the median subjective fatigue score as the cutoff point, and annual changes in the proportion of students in the high subjective fatigue group were investigated by simple regression analysis. In addition, relationships between the two subjective fatigue groups and each item were investigated.
  
  
  RESULTS
  1) The proportion of students with many subjective fatigue symptoms showed a significantly increasing trend over the 15-year period. 2) Investigation of relationships between subjective fatigue symptoms and each factor revealed significance for many items, including dietary habits, life satisfaction, amount of sleep, and desire for a positive body image. 3) In order to determine which of the items were most strongly related to subjective fatigue symptoms, multiple logistic regression analysis was performed for the 15-year period as well as three 5-year periods into which it was divided. The results showed that the dietary habits score (an indicator of dietary habits) and life satisfaction were related to subjective fatigue symptoms during all four periods. As for other items, relationships were observed for amount of sleep in three, diet and salt intake score in two, and liking for coffee/tea, juice drinks, and oily food, bedtime snack, desire for body image, self-assessment of body type, and health consciousness in one.
  
  
  CONCLUSIONS
  These findings indicate that perspectives in education for promoting the health of adolescent girls must include attention to dietary habits, satisfaction with life, and correct awareness of body type.
