Investigation and Analysis of Northwest Universities Teacher’s Physical Sub-Health Status and Its Influencing Factors-A Case Study of Chang'an University

Objectives: To examine the prevalence and influencing factors of physical sub-health among Northwest Universities Teacher. Design: In research, using several methods (including literature material law, questionnaire survey, and mathematical statistics) to give the physical subhealth status, lifestyle and physical exercise habit a more comprehensive understanding. In addition, the correlation analysis will be stated from the influence of lifestyle and exercise habits of the physical sub-health status to discover the influence factors of affecting the body and health. To develop a better understanding of the physical sub-health status, life style and physical exercise habit of subjects, the researchers adopted several methods including systematic literature reviews, questionnaire survey and mathematical statistics. A correlation analysis is conducted to examine the influence of life style and physical exercise habit on subhealth status, so that we can dig out factors contributing to sub-health status based on the analysis. Results: The overall sub-health rate of teachers is 50.7%. Among them, the rate of sub-health status in female teachers is much higher than that of male teachers by 13.8% and 8.6% more than the overall sub-health status rate. Among teachers in all colleges, teachers from foreign language college and automobile experience the most serious physical condition with sub-health status rate of 83.4% and 80.0% respectively. The subhealth rate also varies in different titles of teacher. Professors have the highest chance of having sub-health status, with up to 58.3%, which is 7.6% higher than the overall level. Lecturers with few class hours and with long class hours shows a sub-health rate of 6.3% and 5.4% higher than those with average teaching hours. The rate of teacher’s positive factors is ranked as follows: fatigue factor>somatic discomfort factor>sleep factor>digestive factor. Furthermore, the number of teachers with a normal body mass index is only 63.4% out of the total number. Conclusion: Teachers mainly present in terms of fatigue, pain symptom, teachers in different colleges, genders, ages, academic qualifications, professional titles, different teaching hours and teaching methods indicate different physical and sub-health conditions. The main influencing factors of teachers' sub-health can be attributed to lifestyle and physical exercise. 1) In living pattern, sleeping hours and late-night habits are the factors that affecting the sub-health of the body, and the teachers will have sleep quality problems. The total time of using electronic devices every day is not related to the sub-health state of the body, but the total time spent on electronic devices per day is significantly associated with sleep-positive symptom factors. 2) For eating habits, whether subjects have regular meals and moderate diet or not is the influencing factor of the sub-health status of the body and the positive factors of digestive discomfort. 3) Bad habits (smoking, drinking) are not one of the factors affecting the sub-health of the body. 4) In physical exercise habits, the sports population, frequency of exercise per week, time of each exercise, and intensity of each exercise are factors affecting the sub-health of the body. The degree of correlation with the sub-health status of the body ranked as: sports population> Weekly exercise times>Every exercise time>Every exercise intensity.
