[Sub-health status of the young and middle-aged populations and the relationships among sub-health, sleepness and personality in Hubei province, China].

OBJECTIVE
To investigate the epidemiological condition of the sub-health status of the young and middle-aged persons in urban and rural areas of Hubei province, and to explore the relationships among personality, quality of sleep and sub-health status.


METHODS
Purposive sampling method and Personal Health Status Questionnaire developed by Chinese Academy of Medical Sciences were used to investigate the sub-healthy status of 3187 subjects aged 18 - 55 and evaluate the relationships among sub-health status, personality and the quality of sleep with structural equation model.


RESULTS
Gender, education, marriage, age and occupation were factors influencing the status of sub-health. Among all of the subjects, sub-health status of females were more serious than that of males (P < 0.0001 of all). The divorced, separated and widowed ones were more likely to experience sub-health than other status of marriage (P = 0.0006, P = 0.0102). The sub-health status of the subjects aged 30 - 55 in the urban (P = 0.0197) and low-literacy residents in rural (P = 0.0003) were among the worst. The condition of the sub-health in migrant workers and professional were worse compared to other occupational groups (P = 0.0043). Structural equation model analysis revealed that sub-health status associated with the quality of sleep and the type of characteristics (P < 0.01).


CONCLUSION
Sub-health status did exist among the young and middle-aged persons and was influenced by the quality of sleep and personality. However, it could be adjusted by improving the quality of sleep and personality to prevent sub-health.
