Background
Because of high working intensity, high responsibility, and unexpected situations, health care workers may suffer great work pressure, which may lead to health damage.
Objective
To explore the self-rated health status and its influencing factors such as demographic and occupational-related factors of medical staff in Lanzhou.
Methods
In-service medical staff were selected by using cluster random sampling method from 18 public hospitals in Lanzhou City and were investigated with a self-made questionnaire and the Self-rated Health Measurement Scale (SRHMS). SRHMS includes 48 items in 10 dimensions, which are divided into three sub-scales of physical health, mental health, and social health, and another independent dimension is overall health. The scores were converted into a percentage scale and expressed as the percentage of measured score to full score; a higher score indicated better health, and >70% was considered good health status. t test, Kruskal-Wallis H test, and Spearman correlation were used to analyze the scores of SRHMS and the demographic and occupational-related factors affecting the scores of physical, mental, and social health sub-scales.
Results
A total of 2989 valid questionnaires were recovered. There were statistically significant differences in total score and the scores of physical, mental, and social health among medical staff of different age, educational background, length of service, and weekly working hours groups (P < 0.05). The percentage of total score to full score in the medical staff was 71.41%, but the scores of physical, mental, and social health sub-scales and total scale of selected participants were all lower than the corresponding domestic norms ( t=−3.323, −12.283, −7.157, −9.659, P < 0.05); the percentage of psychological symptoms and negative emotions in mental health scale to full score was the lowest, only 58.39%. Educational background, length of service, and weekly working hours were negatively correlated with physical health score ( r=−0.061, −0.060, −0.165, P < 0.05); professional title was positively correlated with mental health score ( r=0.045, P < 0.05), while educational background and weekly working hours were negatively correlated with it ( r=−0.051, −0.172, P < 0.05). Monthly income, professional title, and length of service were positively correlated with social health score ( r=0.040, 0.049, 0.071, P < 0.05), while educational background and weekly working hours were negatively correlated with it ( r=−0.038, −0.110, P < 0.05).
Conclusion
The self-rated health status of selected medical staff in Lanzhou is generally good, but lower than that of the norm, especially the mental health score is the lowest. The self-rated health score of total scale is correlated with education, length of service, professional title, and working time per week.
