Objective: To examine the mediating effect of positive coping style on health literacy and lifestyle among medical students, so as to provide the reference for health education and health promotion among medical students in universities. Methods: Medical students of six full-time medical colleges in Guizhou Province were sampled using a multi-stage stratified cluster random sampling method from April to June 2023, and their gender, age and educational level were investigated by questionnaires. The College Students' Healthy Lifestyle Scale, the Health Literacy Questionnaire and the Simplified Coping Style Scale were used to evaluate lifestyle, health literacy and coping style of students. The Process program was used to analyze the mediating effect of positive coping style on health literacy and lifestyle, and Bootstrap method was used to examine the significance of the mediating effect. Results: A total of 9 266 peoples were investigated, including 3 177 males (34.29%) and 6 089 females (65.71%), and had a mean age of (21.06±2.61) years. There were 2 775 junior college students (29.95%), 4 864 undergraduates (52.49%) and 1 627 master students (17.56%). The scores of lifestyle, health literacy and positive coping style among medical students were 118.34±19.06, 54.57±10.81 and 2.81±0.68, respectively. Health literacy had a direct positive effect on lifestyle (effect value=0.286, 95%CI: 0.257-0.316) and a indirect positive effect on lifestyle through positive coping style (effect value=0.215, 95%CI: 0.193-0.236), and the mediating effect contributed 42.91% to the total effect. Conclusion Health literacy could improve lifestyle indirectly through positive coping style among medical students.

Objective: To investigate the occupational delay of gratification among community healthcare workers and its influencing factors, so as to provide insights into the sustainable development of primary healthcare personnel. Methods: The in-service community healthcare workers from 5-7 community health service centers in 9 cities (prefectures) of Guizhou Province were selected using a multi-stage stratified random sampling method. Gender, age, and educational level and other basic information were collected through questionnaire surveys. The status of occupational delay of gratification was investigated using the Occupational Delay of Gratification Scale. Multiple linear regression model was used to analyze the influencing factors of occupational delay of gratification. Results: A total of 2 076 respondents were surveyed, including 367 males (17.68%) and 1 709 females (82.32%). There were 112 respondents (5.39%) with secondary vocational school degree or below, 872 respondents (42.00%) with junior college degree, 1 087 respondents (52.36%) with bachelor's degree, and 5 respondents (0.24%) with master's degree or above. There were 665 respondents (32.03%) with managerial positions. The monthly income of 1 705 respondents (82.13%) was ≤5 000 Yuan. The total score of occupational delay of gratification was (33.22±4.33) points, and the total average score was (2.77±0.36) points. The average scores of work delay, career delay and persistence were (2.67±0.48), (2.96±0.45) and (2.75±0.46) points, respectively. Multiple linear regression analysis identified educational level (junior college, β=0.089; bachelor's degree, β=0.088), management position (not have, β=-0.046) and monthly income (>6 000 Yuan, β=0.085) as factors affecting occupational delay of gratification (all P<0.05). Conclusion The community healthcare workers with an education below secondary vocational school, no management position and lower income have relatively lower level of occupational delay of gratification.

Objective: To investigate the current status and influencing factors of emotional intelligence among postgraduates, so as to provide the evidence for promoting the mental health of postgraduates. Methods: The postgraduates from higher education institutions in Guizhou Province were selected using stratified cluster sampling method from November to December 2023. Demographic information such as gender, college, professional discipline and monthly family income were collected using questionnaire surveys. Stress perception was investigated using the Chinese version of the Stress Perception Scale. Emotional intelligence was investigated using the Chinese version of the Emotional Intelligence Scale. The influencing factors for emotional intelligence were analyzed using a multiple linear regression model. Results: Totally 728 valid questionnaires were recovered, with an effective recovery rate of 94.42%. There were 262 males (35.99%) and 466 females (64.01%). The mean score of emotional intelligence was (77.98±15.71) points, the mean score of emotional assessment was (20.57±4.50) points, the mean score of emotional regulation was (18.63±5.22) points, the mean score of emotional using was (18.90±4.87) points, and the mean score of emotional recognition was (19.89±4.73) points. Multiple linear regression analysis revealed that professional discipline (economics and law, β'=0.108), monthly family income (3 000-5 000 yuan, β'=0.091; >5 000 yuan, β'=0.086) and stress perception (β'=-0.515) were associated with emotional intelligence among postgraduates. Conclusion The emotional intelligence among postgraduates was influenced by professional discipline, monthly family income and stress perception.

Objective: To investigate the current status of knowledge and attitudes of oncology nursing staffs on pain management in cancer patients. Methods: A total of 232 oncology nursing staffs from 7 Grade III-A Hospitals in 4 provinces and municipalities were surveyed using General Information Questionnaire and knowledge and attitudes survey regarding pain (KASRP) (2014) questionnaire (Chinese version). Results: The results of this survey showed that the average score of knowledge and attitude about pain management of 232 oncology nursing staffs was (21.56±4.01) points, and the average correct rate was 52.59%. There were no significant differences in the scores of different education background, years of nursing work, years of cancer clinical nursing care, and the nature of the hospital they worked in(P>0.05). However, there was a difference in the score of nursing staffs with different professional titles (F=5.885, P=0.003). Besides that, difference also showed in scores of nursing staffs with different experiences in caring cancer pain patients (F=3.216, P=0.024). Conclusion The knowledge and attitude of pain management in oncology nursing staffs are in low level, the command of knowledge is not enough, meanwhile, the pain management ability is insufficient. Therefore, it is necessary to strengthen the training of pain related knowledge of nursing staffs and improve their pain management ability.
