[Study on the prevalence and risk factors of "subhealth" status in college and university staff in Guangdong province].

OBJECTIVE: To understand the current status and risk factors of "subhealth" in college and university staff in Guangdong province. METHODS: Eight thousand four hundred and seventeen staff in 19 colleges and universities in Guangdong were investigated through a self-developed questionnaire, and statistically analyzed using chi(2) test, chi(2)(strand) test and odd ratio. Judgement was based on the criteria on "subhealth" through Delphi method. RESULTS: Overall incidence of "subhealth" was 69.18% in 8,417 staff members, and the highest was in the age group of 30 - 40 year olds (totally 79.17%). The prevalence of severe "subhealth" in females was significantly higher than that of males (chi(2) = 14.19, P < 0.01). The main risk factors of "subhealth" were occupational stress, psychological factors, bad habits and behaviors. 44.21% of the 8,417 staff were aware of the terminology "subhealth", and 36.84% thought themselves under "subhealthy" condition. CONCLUSION: The health condition of college and university staff in Guangdong was not satisfactory, thus it was essential to carry out active measures of prevention and intervention among this population.
