ABSTRACT
Objective:To explore the factors influencing the supportive communication ability of medical undergraduates, and to propose strategies to improve supportive communication.Methods:By cluster sampling, we selected 388 medical undergraduates of grades 2017 and 2018 from Harbin Medical University for a questionnaire survey on supportive communication, general self-efficacy, and health education abilities. SPSS 22.0 was used for descriptive statistical analysis. AMOS 22.0 was used to construct a structural equation model to verify the relationship between the three variables. Mediating effects were also tested.Results:The students showed good supportive communication ability, with a total score of (74.28±10.84) points. The general self-efficacy score was (27.81±5.58) points, and the total score of health education ability was (25.50±4.76) points. General self-efficacy had direct positive effects on supportive communication and health education abilities ( β=0.75, 0.31, both P<0.001). Health education ability had a direct positive effect on supportive communication ability ( β=0.14, P<0.001). Health education ability played a significant mediating role in the influence of general self-efficacy on supportive communication ability (standardized mediating effect value=0.042, P<0.01), with the mediating effect accounting for 5.1%. Conclusions:The health education competency of medical undergraduates can mediate the effect of general self-efficacy on supportive communication ability. By strengthening medical humanities education to increase general self-efficacy and also emphasizing the cultivation of health education competency, the supportive communication ability of students can be improved.
ABSTRACT
Objective@#To investigate the current status of professional identity among the undergraduates majoring in public affairs management and the related influence factors.@*Methods@#A stratified cluster sampling method was used to conduct a questionnaire survey among the 115 undergraduates majoring in public affairs management in a medical university in Harbin, China, and the contents of the questionnaires included general status and professional identity. The t-test, one-way analysis of variance, and multiple linear regression analysis were used to analyze the influencing factors of professional identity. In-depth interviews were conducted for some students to explore the profound influencing factors for professional identity among the students majoring in public affairs management.@*Results@#The overall level of professional identity was low among the undergraduates majoring in public affairs management in the medical university in Harbin, and the score of professional identity was 3.25±0.56. The scores of cognitive dimension, emotional dimension, behavioral dimension, and applicable dimension were 3.41±0.69, 3.21±0.78, 3.24±0.71, and 3.13±0.72, respectively. The multivariate analysis showed that grade, academic performance, major selection, and children number in family had significant influence on their professional identity. The students who were at grade four, who had high academic record (b=-0.276, P<0.01), who chose this major independently (b=-0.277, P<0.01), and who were the only child (b=-0.233, P<0.05) had a high score of professional identity. As for the undergraduates at different grades, the undergraduates at grades two and three had a significantly lower score of professional identity than those at grade four (b=-0.296 and -0.369, P<0.05), while there was no significant difference between the undergraduates at grades one and four (b=-0.008, P>0.05). Furthermore, the students with a high score of professional identity had higher possibility to pursue the job related to this major than those with a low score (3.39±0.53 vs. 2.92±0.49, t=4.414, P<0.01).@*Conclusion@#Universities should strengthen the publicity of the major of public affairs management, optimize the curriculum, and add job experience, so as to enhance professional identity among students with this major and provide talent for the field of public health management.
ABSTRACT
To explore the mediating role of psychological resilience to childhood abuse and binge eating. This study assessed the childhood abuse, binge eating and psychological resilience of 3 453 middle school students in Harbin city, Heilongjiang Province. SPSS PROCESS macro program, combined with Bootstrap method, was employed to explore the mediating effect of psychological resilience. The incidence of middle school students experiencing at least one type of abuse in their childhood was 81.3% (2 807/3 453). Childhood abuse, psychological resilience and binge eating were all significantly different in terms of gender, household registration and whether they were only child (all P values<0.05). There was a significant positive correlation between childhood abuse and binge eating. Psychological resilience was negatively associated with childhood abuse and binge eating. Childhood abuse could not only directly predict the binge eating behavior of adolescents, but also could indirectly affect it via psychological resilience.

ABSTRACT
Objective To investigate the mediating effects of neurotic personality between parental rearing patterns and depressive symptom.Methods Using multistage sampling method,982 town middle-school students were surveyed by the Symptom Checklist 90(SCL-90),the Egna Minnen av Barndoms Uppfostran (EMBU),the Eysenck Personality Questionnaire (EPQ).Correlation and regression analysis,mediating effect test,and structural equation model were constructed.Results ①)Depressive symptom (D) (1.73 ± 0.72) was significantly associated with Neurotic personality (N) (51.50± 11.37) and parental rearing patterns (r=-0.138-0.582,P<0.01).②N,mother's rejection and deny(M3),father's emotional warmth and understanding(F1),father's over-protection(F6) had a direct effect on D,which can explain 41.6% of the variance.F1,F6,mother's over-interference and over-protection(M2),M3 had a direct effect on N,which can explain 15.3% of the variance.The mediating effect of N between F1,F6,M2 and D were significant(95%CI =-0.212--0.069,-0.351--0.233,0.414-0.480).③The explanation for D was 41.3%.N had completely mediating effect between M2 and depressive symptom.N had partial mediating effect between F1,F6 and D,and the proportion was 43.6% and 49.1%.Conclusion Neurotic personality plays a mediating role between parental rearing patterns and depressive symptom in middle-school students.
ABSTRACT
Objective To understand the risk factors for cardiovascular disease(CVD)and their clustering among middle aged and old people in Jilin province and provide evidence for the development of effective intervention measures. Methods A total of 13 914 people aged 35-79 years were selected from 32 counties (district) in 9 prefectures (municipality) of Jilin province through multi-stage stratified cluster sampling to conduct a face to face questionnaire survey and health examination. Complex weighted computation was conducted to analyze the survey results. Results The prevalence of hypertension,diabetes,dyslipidemia,smoking and overweight were 41.3%,11.5%, 42.8%,31.5%and 53.5%,respectively. Only 16.2%of the subjects surveyed were free of the 5 risk factors.≥1 risk factor and≥3 risk factors were found to clustering in 83.8%and 29.9%of the middle aged and old people. Compared with females,the odds ratios of ≥1,≥2 and ≥3 risk factors clustering in males were 3.18,4.28 and 5.58 times higher,respectively. Compared with urban residents,the odds ratios of≥1,≥2 risk factors clustering in rural residents were 1.22 and 1.20 times higher. In addition,the odds ratios of≥1,≥2 and≥3 risk factors clustering increased with age(all P<0.001). Conclusion High prevalence of major cardiovascular disease risk factors and their clustering were found in middle aged and old people in Jilin province. More attention and intervention should be given to the old males in rural areas.
ABSTRACT
Objective To compare the impact of tobacco control curriculum on self-efficacy of tobacco control in different major of public health students, and offer theoretical foundation for improving tobacco control curriculum.Methods We offered tobacco control curriculum for 150 public health students (including students of preventive medicine and public service administration research direction) in medical university of Harbin, and investigated twice general self-efficacy, smoking selfefficacy and tobacco control self-efficacy before and after tobacco control curriculum, then compared intervention effects between two major students by t test.Results There were no differences of tobacco control self-efficacy, smoking self-efficacy and general self-efficacy between two major students, t values were-0.832 (P=0.407), 0.190 (P=0.849) and-0.492 (P=0.624).The tobacco control self-efficacy (t=-3.566, P=0.001) and general self-efficacy (t=-2.237, P=0.028) increased remarkably but smoking self-efficacy (t=-1.102, P=0.273) in preventive medicine students after intervention.And all of three kinds of self-efficacy were not gotten better by intervention in public service administration students.There was no obvious difference of intervention effects between tobacco control self-efficacy and general self-efficacy among preventive medicine students (t=1.541, P=0.125).Conclusions The improvement of preventive medicine students by tobacco control curriculum is better than that of public service administration students.We should further perfect the tobacco control course, and on the one hand, improve the intervention effect of students majoring in course of public health management;on the other hand, strengthen the target effects of the tobacco control curriculum to students' tobacco control self-efficacy and smoking self-efficacy.

Objective To study the ages at natural menopause of the women in Jilin Province, and to illustrate its influencing factors among the women in Jilin Province.Methods Through multistage stratified cluster random sampling method,23 050 people aged from 18 to 79 years were drew from nine states(a total of 32 areas)of Jilin province.The data of these residents were collected with the questionnaire and physical examinations by face-to-face interview.The number of selected female sample was 11 098. Finally, 4 881 postmenopausal women were selected.Complex weighted computation was used to estimate the ages at natural menopause.One-way ANOVA was used to compare the ages at natural menopause of the women with different birth years. Multiple linear regression analysis were used to examine the influencing factors of the ages at natural menopause. Results The mean and median ages at natural menopause were (49.11±4.19)years and 50.00 years,respectively.There were 4 881 cases of postmenopausal women,among them the women with age at natural menopause<40 years,40 year≤age at natural menopause≤45 years,46 years≤ age at natural menopause≤53 years,age at natural menopause≥54 years and age at natural menopause missing accounted for 2.27%(111 cases),13.17%(643 cases),71.97%(3 513 cases),11.74% (573 cases),and 0.85%(41 cases),respectively.Converted to birth years by age,70-79 years old was 1933-1942 birth years,60-69 years old was 1943-1952 birth years and 57-59 years old was 1953-1955 birth years.The age at natural menopause in Jilin province was statistically significant among the women with different birth years(F=21.178,P<0.001).By SNK-q test among three different birth year groups, the age at natural menopause was different between any two groups among three different birth year groups and the ages at natural menopause of 1953-1955 birth year group,1943-1952 birth year group and 1943-1952 birth year group were 50.38 years,49.51 years and 48.81 years.The age at natural menopause in urban of Jilin province was statistically significant among the women with different birth years(F=16.633,P<0.001).By SNK-q test among three different birth year groups,the age at natural menopause was different between any two groups among three different birth year groups and the ages at natural menopause of 1953-1955 birth year group,1943-1952 birth year group and 1943-1952 birth year group were 50.77 years,49.73 years,and 48.85 years,respectively.The age at natural menopause in rural of Jilin province was statistically significant among the women with different birth years(F=7.400,P=0.001 ). By SNK-q test among three different birth year groups, the age at natural menopause was different between 1953-1955 birth year group and the other two groups and the ages at natural menopause of 1953-1955 birth year group,1943-1952 birth year group and 1943-1952 birth year group were 50.09 years,49.33 years,and 48.74 years,respectively.The multiple linear regression results indicated that BMI and exercise were positively correlated with the age at natural menopause,but smoking and mental health evaluation were negatively.Consumption frequency of vegetables,fruits,bean products,and meat was no correlated with the age at natural menopause.Conclusion The differences of the ages at natural menopause between the women with different birth years are statistically significant in Jilin Province;BMI, smoking, exercise,and mental health are the influencing factors of the age at natural menopause.
ABSTRACT
Objective To investigate the clinical effects of different doses of propranolol in treatment of infantile mixed and deep hemangioma,and to provid theoretical and experimental evidence for the treatment of hemangioma. Methods The selected 62 patients with mixed and deep hemangioma were divided randomly into low dose (1.5mg·kg-1 ·d-1 )and high dose (3.0 mg·kg-1 ·d-1 )of propranolol groups,3 times a day,6 months as a course,the changes in hemangioma size and the incidence of adverse reactions were recorded.Results The efficacy was evaluated using Achauer system.The total effective rate was 80.65% in low dose of propranolol group and 93.55% in high dose of propranolol group,including 6 cases of class Ⅰ (poor),9 cases of class Ⅱ (moderate), 11 cases of classⅢ (good),and 5 cases of class Ⅳ (excellent)in low dose propranolol group;while 2 cases of class Ⅰ (poor),4 cases of class Ⅱ (moderate),10 cases of class Ⅲ (good)and 15 cases of Ⅳ (excellent)in high dose of propranolol group.The efficacy in high dose of proprandol group was significantly better than that in low dose of proprandol group (P0.05)and there was no significant difference in the incidence of adverse reaction between two groups (P>0.05).Conclusion The efficacy of oral 3.0 mg·kg-1 ·d-1 propranolol in treatment of infantile mixed and deep hemangioma is increased significantly, and there is no significant adverse reactions after increasing doses.Therefore,high dose of propranolol should be recommended in order to improve the therapeutic effect.

ABSTRACT
Objective To explore the direct effect of attachment and the indirect effect through coping style and social support on mental health in technical school students. Methods 372 technical school students were assessed by Experiences in Close Relationship' s Inventory ( ECR), Symptom Check Scale List-90 ( SCL90) ,Coping Style Scale For Secondary School Students( CSS)and Perceived Social Support Scale(PSSS). Results ( 1 ) Total score of SCL-90 had significant correlations with all index of attachment anxiety, parents attachment avoidance( r=0. 165 ~0.370, P<0.01 ) ,with coping style focus on problem ( r=0.291 ~0.552, P<0. 01 ) and perceived social support( r = -0. 245, P < 0.01 ). (2)Coping style focus on emotion had significant correlations with attachment anxiety( r=0.237 ~0.383, P<0.01 ) and coping style focus on problem had significant correlations with attachment avoidance( r= -0. 267 ~ -0. 403, P<0. 01 ). (3) Perceived social support had significant negative correlations with attachment avoidance ( r= - 0. 425 ~ - 0. 459, P < 0.01 ). (4) The coping style focus on emotion had 65.2% mediation effect between attachment anxiety and mental health and perceived social support was moderated by attachment avoidance. Conclusions ( 1 ) Attachment anxiety and attachment avoidance have direct effect on mental health. ( 2 ) The indirect effect of attachment anxiety on mental health is a lot mediating effect performed by the coping style focus on emotion. Attachment avoidance also indirectly influences on mental health by moderating perceived social support.
