The purpose of this study is to examine the relationship between the Index of Life Satisfaction Levels (LSL), lifestyle factors and health conditions from the viewpoint of health education at school. The subjects of the analysis were 966 (479 males and 487 females) high-school students in Okayama prefecture. The survey was conducted in April, 2010. The main results were as follows:
In one item out of 19 items, there was a significant difference between males and females as for the index of life satisfaction levels. Gender differences, however, were not observed in the average of LSL scores.
The comparison of LSL scores and subjects' lifestyles showed that grade, bed time, time of sleep, regularity of bed time, snoozing during class, learning time in home, exercise and sport, regularity of dinner time, combinations of foods, sense of sufficiency for sleep, feeing of awakening, appetite and self-assessment of health were influential for males. For females, on the other hand, grade, bed time, time of sleep, regularity of bed time, snoozing during class, regularity of dinner time, nutrient balance scores, sense of sufficiency for sleep, feeing of awakening, self-assessment of health and self-assessment of body were influential.
The comparison of LSL scores by categories of health conditions showed that a gender difference was observed in the average number of subjective symptoms. Those who have fewer subjective symptoms were likely to have higher LSL scores. As for BMI, females with overweight trends were likely to have lower LSL scores.
The results of logistic regression analysis showed that LSL was related to self-assessment of health, combinations of foods, and sleep time for males. For females, on the other hand, LSL was related to self-assessment of health, and feeing of awakening.
The above results show that self-assessment of health, quality or quantity of sleep and well-balanced dietary habits are related to high school students' life satisfaction levels.
