Association between exposure patterns of adverse childhood experiences and anxiety symptom trajectories in medical college students / 中华预防医学杂志

Objective: To analyze the association between exposure patterns of adverse childhood experiences (ACEs) and anxiety symptom trajectories in medical college students. Methods: A survey was conducted on first-year students from Anhui Medical College and Anqing Medical College, using the Childhood Abuse Questionnaire, Family Disability Questionnaire, Childhood Adverse Social Experience Item, and Anxiety Self Rating Scale. The baseline survey was conducted from November to December 2019, and two follow-up visits were conducted once every six months until November to December 2020. The latent class analysis (LCA) was used to analyze the exposure patterns of ACEs. The latent class growth analysis (LCGA) was used to analyze the development trajectory of anxiety symptoms. The multiple logistic regression model was used to analyze the correlation between different exposure patterns of ACEs and the trajectory of anxiety symptom trajectories. Results: A total of 3 662 college students aged (19.2±1.0) were surveyed. The LCA showed that the exposure patterns of ACEs could be divided into the "high ACEs" group (13.4%), "high neglect/emotional abuse" group (25.7%), "high family dysfunction" group (6.9%), "high neglect" group (27.1%), and "low ACEs" group (26.3%). The LCGA divided anxiety trajectories into four groups: "high anxiety decline" (7.1%),"anxiety increase "(4.1%), "moderate anxiety"(52.9%), and "low anxiety"(35.9%). Using the low ACEs group as a reference group, compared with the low anxiety trajectory, the high ACEs group, high neglect/emotional abuse group, high family dysfunction group, high neglect group, and medium to high-level anxiety trajectory were all associated with an increased risk (P<0.05). Conclusion: There is heterogeneity in ACEs exposure patterns among medical college students, and ACEs exposure patterns are important influencing factors for anxiety symptom trajectories.

Application of entropy weight TOPSIS comprehensive method in the evaluation of students' physical health level / 中华预防医学杂志

Objective: To comprehensively evaluate the physical health level of students of different school-age segments in four regions of Anhui province using the entropy weight approximation ideal solution ranking method (TOPSIS), and to provide a scientific method and basis for conducting school health work evaluation. Methods: Using the physical fitness survey data of four regions in Anhui province, the entropy weight method was used to draw the weights of various indicators for different school-age segments of men and women. Then, the TOPSIS method was used to evaluate the school-age segments of men and women in the four regions. Finally, the physical health level of students in four regions was classified according to the results of entropy weight TOPSIS and the rank sum ratio method. Results: A total of 10 127 students were included in this study, with an average age of (11.85±3.82) years, including 5 050 males (49.8%) and 5 072 urban students (50.1%). The results of the entropy weight method showed that the weight of body mass index of boys was similar to that of girls in each school-age segment. According to the TOPSIS and rank sum ratio analysis, the physical health level of students in the four regions of Anhui province was different. The physical health score of Suzhou was 0.617 4 points, which was classified as the best grade. The scores of Hefei and Wuhu were 0.556 3 and 0.411 2, which were classified as middle. Jiju City scored 0.381 9 points, which was classified as poor. Conclusion: TOPSIS combined with rank sum ratio can reflect the level of students' physical health, which can be applied to the evaluation of students' physical health and provide a basis for monitoring students' physical health .

The role of mother-child relationship in the association between maternal parenting stress and emotional and behavioral problems in preschool children / 中国当代儿科杂志

OBJECTIVES@#To study the moderating effect of mother-child relationship in the association between maternal parenting stress and emotional and behavioral problems in preschool children, and to provide reference for the prevention and control of emotional and behavioral problems in preschool children.@*METHODS@#Using a stratified cluster sampling method, 2 049 preschool children were surveyed from November to December 2021, who sampled from 12 kindergartens in Wuhu City, Anhui Province. The emotional and behavioral problems of preschool children were assessed with the Strength and Difficulties Questionnaire. Pearson correlation analysis was used to evaluate the relationship of maternal parenting stress and mother-child relationship with children's emotional and behavioral problems. The PROCESS Macro was used to analyze the moderating effect of conflicted and dependent mother-child relationships in the association between maternal parenting stress and emotional and behavioral problems in these preschool children.@*RESULTS@#Among these preschool children, maternal parenting stress was positively correlated with the scores of emotional symptoms, conduct problems, hyperactivity, and peer problems subscales and total difficulty scores (P<0.001); intimate mother-child relationships were negatively correlated with the scores of conduct problems, hyperactivity, and peer problems subscales and total difficulty scores (P<0.001); conflicted and dependent mother-child relationships were positively correlated with the scores of emotional symptoms, conduct problems, hyperactivity, and peer problems subscales and total difficulty scores (P<0.001). After controlling for relevant confounding factors, conflicted mother-child relationship (β=0.05, P=0.001) and dependent mother-child relationship (β=0.04, P=0.012) were found to have a moderating effect on the association between maternal parenting stress and total difficulty scores in these preschool children.@*CONCLUSIONS@#Negative mother-child relationships play a moderating role in the association between maternal parenting stress and emotional and behavioral problems in preschool children. Prevention of emotional and behavioral problems in preschool children should focus on reducing maternal parenting stress and improving negative mother-child relationships.

Interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students / 中华预防医学杂志

To explore the interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students. From November 2015 to January 2016, 22 628 middle school students from Shenyang of Liaoning Province, Bengbu of Anhui Province, Xinxiang of Henan Province, Ulanqab of Inner Mongolia Autonomous Region, Chongqing Municipality, and Yangjiang of Guangdong Province were enrolled by using the multi-stage cluster convenience sampling method. A questionnaire was used to collect the data including demographic information, health literacy, second-hand smoke exposure, and psychopathological symptoms. A multivariate logistic regression model was used to analyze the interaction of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students. The age of students was (15.36±1.79) years old, of which 10 990 were boys, accounting for 48.6% of total students. The detection rate of psychopathological symptoms was 29.1% (6 581/22 628). The detection rate of psychopathological symptoms in those who were exposed to second-hand smoke was 38.1% (2 401/6 304), which was higher than that in the non-second-hand smoke exposure group [25.6% (4 180/16 324)] (0.001). The (95) of the interaction between medium and low levels of overall health literacy, low level of interpersonal dimension of health literacy and second-hand smoke exposure was 1.19 (1.15-1.24), 2.00 (1.92-2.10) and 1.59 (1.52-1.66), respectively. There was a positive interaction between middle and low levels of overall health literacy, low level of interpersonal dimension of health literacy and second-hand smoke exposure on psychopathological symptoms of middle school students.

Relationships between different forms of social support and suicidal ideation and gender differences analysis among medical college students in Anhui Province / 中华疾病控制杂志

@# Objective To investigate the relationship between various types of social support and suicide ideation, and whether the relationship varies by gender. Methods A total of 4 799 students in cluding freshmen and sophomores were recruited by stratified cluster sampling from 2 medical colleges in Anhui Province. We assessed demographic indicators, social support and suicidal ideation, etc. Logistic regression was used to analyze their gender differences and the relationship between social support and suicidal ideation. Results The prevalence of suicidal ideation was 6.2%, and no gender difference was found ( 2=1.224，P=0.269). The rate of suicidal ideation was higher with the decreasing of social support. Low levels of social support had independent effects on suicidal ideation among total samples and females respectively after controlling for confounding factors (all P<0.05), while low levels of social support, subjective social support and support availability increased the risk of suicidal ideation among males (P value was 0.049，0.002，0.031, respectively). In adolescents with low levels of social support, objective social support and various sources of social support, females versus males had higher risk to have suicidal ideation. Conclusions Low level of social support increased the risk of suicidal ideation among students in medical college, especially for girls. Groups at highest risk of suicidal ideation in relation to certain types of social support should be targeted with interventions accordingly.

Situation of common psychosomatic symptom in adolescent and its influence on 6 months later suicide and self-injurious behavior / 中华预防医学杂志

<p><b>OBJECTIVE</b>To investigate the prevalence of common psychosomatic symptoms among Chinese adolescents and the influence on 6 months later suicide and self-injurious behavior.</p><p><b>METHODS</b>Based on the cluster sampling method, the participants who were recruited from 8 cities from 3 areas in China, including Eastern areas (Beijing, Shaoxing and Guangzhou), Middle areas (Ezhou, Harbin and Taiyuan) and Western areas (Guiyang and Chongqing), were administered by multidimensional sub-health questionnaire of adolescents (MSQA) in March 2008. Demographics, life style, psychosomatic symptoms, suicide and self-injurious behavior were also assessed. A total of 17 622 questionnaires were valid at baseline. Six months later, 14 407 questionnaires were eligible for two waves investigation. Analysis of Pearson chi-square and logistic model regression analysis were employed to compare the incidence of psychosomatic symptoms, suicide and self-injurious behaviors among different areas and to explore the possible risk factors of those symptoms and behaviors.</p><p><b>RESULTS</b>At baseline, rates of total common physiological and psychological symptoms were 24.1% (4255/17622) and 30.9% (5447/17622), respectively, with the highest being eating and drinking too much (6.4%, 1130/17622) and hardly feel ease to learn at home (11.8%, 2087/17 622). In males, the rate of common psychological symptoms (30.7%, 2637/8599) was higher than physiological symptoms (24.0%, 2061/8599) (P < 0.05); in females, the rate of common psychological symptoms (31.1%, 2810/9023) was higher than physiological symptoms (24.3%, 2194/9023) (P<0.05). The rate of the common psychosomatic symptoms in senior high school students (46.8%, 2905/6208) were significantly higher than those in middle high school students (37.3%, 2337/6262) and college students (33.2%, 1711/5152) (all P values <0.05). Students from Western areas had the highest incidences of the common physiological and psychological symptoms (30.2%, 1471/4871; 40.6%, 1979/4871), higher than students from Middle areas (22.4%, 1443/6453; 27.0%, 1743/6453) and Eastern areas (21.3%, 1341/6298; 27.4%, 1725/6298) (all P values <0. 05). Results from multiple logistic regression showed that physical symptoms > or = 2 at baseline were shared risk factors for suicidal ideation (RR = 1.44, 95% CI:1.16 - 1.79), attempted suicide (RR = 1.79, 95% CI: 1.22 - 2.61) and self-injurious behaviors (RR = 1.39, 95% CI: 1.17 - 1.66) 6 months later. Psychopathological symptoms > or = 4 at baseline was the shared risk factors for suicide ideation (RR = 1.74, 95% CI: 1.39 -2.17), attempted suicide (RR = 2.08, 95%CI: 1.39 - 3.11) and self-injurious (RR = 1.90, 95%CI: 1.59 - 2.28) 6 months later.</p><p><b>CONCLUSION</b>It is common in Chinese adolescents who have multiple psychosomatic symptoms simultaneously. What's important is that those common psychosomatic symptoms are shared risk factors of later suicidal and self-injurious behaviors.</p>

Relationship between deliberate self-harm and suicidal behaviors in college students / 中华流行病学杂志

Objective To describe the prevalence of deliberate self-harm (DSH) and suicidal behaviors (SIB) as well as the relationship between them in a college student population.Methods A total of 4063 medical students were selected under the cluster sampling method in Anhui province.Data were analyzed by Pearson Chi-square and logistic regression.Results A total of 4063 ( 13.4％ )students reported that they had deliberately harmed themselves during the past 12 months.The acts of DSH with 1 and more than or equal to 2 times occurrence accounted for 3.7％ and 9.6％ among all the respondents.The act of DSH was significantly higher among boys than that among girls.Rates of suicide ideation,suicide plan,attempted suicide and SIB in the last year were 4.5％,1.4％,0.6％ and 4.9％,respectively.However no statistically significant difference was found in different sex.Students in the DSH group that with SIB were found to have lower positive coping levels (OR=0.5,95％CI:0.3-0.8),getting less support from fricnds (3-5 vs.less than or equal to 2:OR=0.6,95％CI:0.3-0.9;more than or equal to 6 vs.less than or equal to 2:OR=0A,95％CI:0.2-0.8),with higher negative coping levels (OR=2.1,95％CI:1.2-3.7),having more serious depressive symptoms (OR=2.9,95％ CI:1.6-5.2) and anxiety symptoms (OR=2.2,95％ CI:1.2-3.8),having more serious sleeping problems (OR=1.7,95％CI:1.1-2.8 ) and perceived fat (fat vs.moderate:OR=2.0,95％CI:1.1-3.6) than the DSH group without SIB.The rates of SIB in students with DSH behavior were significantly higher than those in students without those behaviors (OR=4.7,95％ CI:3.5-6.4).Psyehosocial variables could attenuate the relationship between the DSH status and suicidal events (OR=3.3,95％CI:2.4-4.5).The DSH frequency exhibited a curvilinear relationship to SIB (OR=3.1-10.0) and psychosocial variables also attenuated this relationship (OR=2.4-5.9).Conclusion It was well known that SIB was not a suicidal gesture but our findings suggested that the presence of DSH might trigger the suicidal attempts.

Coping as a mechanism linking stressful life events and mental health problems in adolescents / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>Although stressful life events represent an etiologic factor of mental health problems in adolescents, few studies have been conducted to address mechanisms linking the stress-psychopathology relation. The present study was designed to examine coping as a mediate factor on the relationship between stressful life events and symptoms of anxiety and depression.</p><p><b>METHODS</b>The participants were 13 512 students from eight cities of China, who participated in a school-based survey. Data were collected by a questionnaire comprising coping, stressful life events, anxiety, and depressive symptoms. As a model, a series of regression equations were used to examine whether coping mediated the association between stressful life events and symptoms of anxiety and depression.</p><p><b>RESULTS</b>Each dimension of stressful life events showed significant correlation with anxiety, depression and coping (all P<0.001). In the model to analyze mediate effects, all standardized coefficients (β) were significant (all P<0.01), indicating marked mediator effects. Furthermore, negative coping might account for more mediate effects than positive coping on this relationship.</p><p><b>CONCLUSION</b>Coping partially mediated the relationship between stressful life events and mental health during adolescence. This study highlighted an important public health priority for preventive interventions targeting stress-related psychopathology, and for further promoting adolescents' mental health.</p>

Impact of psychosocial factors on suicide attempts in high school and college students, data from eight cities of China / 中华流行病学杂志

Objective This paper aimed to report the rate of suicide attempts among adolescent and young students of eight cities in China, and to examine the impact of related psychosocial factors on suicide attempts. Methods The investigation was obtained in senior and junior high school and college students in eight cities of China. All of the 17 622 participants were recruited to complete anonymous questionnaires regarding their experiences of suicide attempts and related psychosocial factors. Results Overall, 2.2 percent of the respondents reported that they had experienced attempted suicide during the previous year. Scores on high anxiety (OR=2.61,95%CI: 1.64-4.16),high depression (OR=2.05, 95%CI: 1.35-3.10),suicide idea (OR= 14.21, 95%CI: 9.88-20.43),suicide plan(OR=3.50,95%CI:2.59-4.73) were revealed as common risk factors while the whole time span being accompanied by mothers during juvenile years (OR=0.38, 95% CI: 0.20-0.74) seemed to be protective factor for suicide attempts through multivariate logistic regression analysis. Conclusion Our results showed that emotional symptom, idea and plans for suicide were statistically associated with suicide attempted in high school and college students.
