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 .

Objective: To investigate the role of methylation of placental glucocorticoid response gene in the association between pregnancy-related anxiety in the third trimester and birth outcomes. Methods: Based on a prospective cohort study, singleton live births and their mothers from the Ma'anshan Birth Cohort Study (MABC) were included as participants in this study. The maternal pregnancy-related anxiety symptoms in the third trimester of pregnancy were evaluated by using the Pregnancy-related Anxiety Questionnaire. The neonatal birth outcomes were collected from medical records. The placental tissues from 300 pregnant women with pregnancy-related anxiety and 300 without pregnancy-related anxiety were collected to detect the methylation of FKBP5, NR3C1 and HSD11B2 genes using the Methyl Target approach. The methylation factors were extracted by exploratory factor analysis. Linear regression or logistic regression models were used to analyze the association between pregnancy-related anxiety in the third trimester, methylation factor scores, and birth outcomes. The mediating role of methylation factors in the association between pregnancy-related anxiety in the third trimester and birth outcomes was analyzed by using the Process procedure. Results: The mean age of 2 833 pregnant women was (26.60±3.60) years old. After adjusting for confounding factors, pregnancy-related anxiety in the third trimester increased the risk of small-for-gestational-age (OR=1.32, 95%CI:1.00-1.74). A total of 5 methylation factors were extracted, and the factor 5 was loaded with FKBP5 CpGs 18-21. Pregnancy-related anxiety in the third trimester was negatively correlated with the factor 5 (β=-0.24,95%CI:-0.44--0.05). The factor 5 was positively correlated with the gestational age (β=0.17, 95%CI:0.06-0.27). In addition, the factor 2 (β=0.02,95%CI:0.00-0.04) and factor 3 (β=0.03,95%CI:0.01-0.05) were positively correlated with 5-min Apgar score after delivery. However, this study did not found the mediating role of the scores of the factor characterized by FKBP5 in the relationship between pregnancy-related anxiety and birth outcomes. Conclusion: Pregnancy-related anxiety in the third trimester may reduce the methylation level of FKBP5 CpGs 18-21 in placental tissues and is associated with the risk of small-for-gestational-age.

The behavioral problems of children and adolescents are becoming more and more serious, and the prevalence rate is increasing year by year. The overall trend is increasing, which has become one of the important public health issues of global concern. There are many influencing factors for behavioral problems in children and adolescents, including genetic, psychosocial, family and early life environment. Among them, maternal screen exposure during pregnancy is a contributing factor that deserves attention and has practical intervention significance. This study systematically evaluated the association between maternal mobile phone screen time during pregnancy and children's internalizing and externalizing behavioral problems, its potential biological mechanisms and relevant intervention measures, in order to create a good intrauterine environment for fetal neurodevelopment and further reduce the occurrence of children's behavioral problems.

Adolescents are in a transition period from children to adults, during which they are prone to a variety of emotional disorders, with anxiety and depression being the most common disorders. Anxiety and depressive symptoms are highly correlated and the comorbidity of anxiety and depression is common. At the same time, the most prominent behavioral changes in adolescence are the emergence of getting up late and sleeping late, and the circadian rhythm begins to delay. Previous studies have shown that circadian rhythm is closely related to anxiety and depression, but the association between circadian rhythm disorder and comorbidity of anxiety and depression remains unclear. This article reviews the prevalence, association and potential biological mechanism of circadian rhythm disorder and comorbidity of anxiety and depression in adolescents, so as to provide a possible reference for the prevention and control of comorbidity of anxiety and depression in adolescents.

Objective To investigate the status of mental health in preschool children of Yangzhou city, and to explore the effect of home environment. Methods A total of 2 531 children from 7 kindergartens were selected by random cluster sampling. Questionnaire (including SDQ tests) was used to analyse the status and characteristics of mental health. Results The rate of children with mental disorder was 6.4%, the most prominent problem was peer relationship difficulty (17.8%), followed by hyperactivity/inattention (13.7%), prosocial behavior (9.4%), conduct problems (7.0%) and emotional problems (5.7%). Except for emotional symptoms, the detection rates of all other investigated problems among boys were higher than those among girls. Logistic regression analysis showed that the low level of mother's education (OR=1.85, 95%CI:1.04-3.29) and the joint family (OR=1.81, 95%CI:1.19-2.75) were risk factors, and gender of girl was protective factor (OR=0.71,95%CI:0.51-0.98). Conclusions The rate of mental disorder is low, but hyperactivity in boys and emotional problems in girls are quite popular, especially in children who have mother with low level of education or live in the joint family.

OBJECTIVE@#To investigate the molecular mechanisms of the adverse effects of exposure to sulfamonomethoxin (SMM) in pregnancy on the neurobehavioral development of male offspring.@*METHODS@#Pregnant mice were randomly divided into four groups: control- (normal saline), low- [10 mg/(kg•day)], middle- [50 mg/(kg•day)], and high-dose [200 mg/(kg•day)] groups, which received SMM by gavage daily during gestational days 1-18. We measured the levels of short-chain fatty acids (SCFAs) in feces from dams and male pups. Furthermore, we analyzed the mRNA and protein levels of genes involved in the mammalian target of rapamycin (mTOR) pathway in the hippocampus of male pups by RT-PCR or Western blotting.@*RESULTS@#Fecal SCFA concentrations were significantly decreased in dams. Moreover, the production of individual fecal SCFAs was unbalanced, with a tendency for an increased level of total fecal SCFAs in male pups on postnatal day (PND) 22 and 56. Furthermore, the phosphatidylinositol 3-kinase (PI3k)/protein kinase B (AKT)/mTOR or mTOR/ribosomal protein S6 kinase 1 (S6K1)/4EBP1 signaling pathway was continuously upregulated until PND 56 in male offspring. In addition, the expression of Sepiapterin Reductase (SPR), a potential target of mTOR, was inhibited.@*CONCLUSION@#In utero exposure to SMM, persistent upregulation of the hippocampal mTOR pathway related to dysfunction of the gut (SCFA)-brain axis may contribute to cognitive deficits in male offspring.

<p><b>OBJECTIVE</b>To investigate the impact of college students' evening exercise on their sleep quality, so as to provide a scientific basis for college students to choose an appropriate method of exercise and improve their sleep quality.</p><p><b>METHODS</b>From September to October in 2012, Multi-stage cluster random sampling method was used to select the 5997 college students in Anhui province. The status of college students' exercise and their sleep quality were investigated by the general situation questionnaire, Physical activity rating scale-3(PARS-3), Rating of perceived exertion(RPE) and Pittsburgh sleep quality index(PSQI). Kruskal-Wallis test was used to analyze the impact of evening exercise on sleep quality and multivariate unconditional logistic regression was used to analyze the factors of sleep quality in evening excise students.</p><p><b>RESULTS</b>The median of PSQI total score among 5806 college students was 5 and 1030(17.7%) students had poor sleep quality. The median of the PSQI scores was the same (5 points) for evening exercise group, daytime exercise group,daytime and evening exercise group and non-exercise group (1406, 1514, 1244, 1642 respectively). The difference was not statistically significant (χ(2) = 2.80, P = 0.42). Compared to non-exercise population, the OR (95%CI) value of evening exercise' impact on sleep quality was 0.90(0.73-1.10). Compared to very light evening exercise, the OR (95%CI) value of moderate and large amount of evening exercise' impact on sleep quality was 0.58 (0.44-0.75) and 0.67 (0.48-0.93) respectively; Compared to other sports, the OR (95%CI) value of badminton, rope skipping and jogging' impact on sleep quality was 0.72 (0.55-0.93), 0.38 (0.21-0.70) and 0.76 (0.60-0.95) respectively and they were all protective factors of sleep quality. Compared to small exercise intensity, the OR (95%CI) value of moderate, vigorous and very vigorous exercise intensity' impact on sleep quality was 1.68 (1.13-2.52), 2.38 (1.48-3.83) and 3.18 (1.72-5.90) respectively and they were harmful factors of sleep quality.</p><p><b>CONCLUSION</b>There was no impact of evening exercise on sleep quality for college students.

<p><b>OBJECTIVE</b>To explore possible interrelationships among resistance to peer pressure, risky decision-making and health risk behaviors among young adolescents.</p><p><b>METHODS</b>Based on the cluster sampling method, the participants who were recruited from 5 junior middle schools in Guangzhou and 3 junior middle schools in Shenyang city on October, 2010, were administered to complete the questionnaire concerned with their experiences with drinking and smoking during the past 30 days preceding the survey, and the hours using computer daily both in weekdays and in weekend. The level of resistance to peer influence and risky decision-making were assessed by Resistance to peer influence scale (RPIS) and Youth decision-making questionnaire (YDMQ). Logistic regression was used to explore possible interrelationships among resistance to peer influence, risky decision-making and health risk behaviors among young adolescents.</p><p><b>RESULTS</b>A total of 1985 questionnaires were valid, including 1001(50.4%) boys and 984 (49.6%) girls. About 27.1% (537/1985) junior middle school students reported having health risk behaviors, boys' (30.7%, 307/1001) was higher than girls' (23.4%, 230/984) with significant gender difference (P < 0.05). The prevalence of smoking, drinking during the past 30 days before the survey and using computer over 3 hours daily in weekdays and in weekend were 5.1% (102/1985), 14.3% (284/1985), 3.5% (70/1985) and 13.7% (272/1985), respectively. The rate of drinking, using computer over 3 hours daily in weekdays and in weekend were higher in males (16.4% (164/1001), 4.5% (45/1001), 16.2% (162/1001)) than those in females (12.2% (120/984), 2.5% (25/984), 11.2% (110/984)) (P < 0.05). The scores of RPIS and YDMQ of the two cities adolescents were 2.82 ± 0.39 and 1.68 ± 0.62. The students reported smoking, drinking during the past 30 days before the survey and using computer over 3 hours daily in weekend gained lower RPIS scores (2.43 ± 0.40, 2.61 ± 0.41, 2.77 ± 0.40) than their counterparts who didn't report these kind of health risk behaviors (2.84 ± 0.38, 2.85 ± 0.38, 2.82 ± 0.39)(P < 0.05). And those reported smoking, drinking during the past 30 days before the survey and using computer over 3 hours daily in weekdays and in weekend gained higher YDMQ scores (2.38 ± 0.66, 2.06 ± 0.66, 1.97 ± 0.72, 1.84 ± 0.64, respectively) than their counterparts who didn't report these kind of health risk behaviors (1.64 ± 0.38, 1.61 ± 0.58, 1.67 ± 0.61, 1.65 ± 0.61, respectively) (P < 0.05). After adjusting gender, area, parental education degree, self-reported family economic condition, multi-variant logistic regression analysis indicated that the low and middle level of resistance to peer influence (low and middle level vs high level, had odds ratios of 2.97 (1.96 - 4.50) and 1.51 (1.05 - 2.16)), and also the middle and high level of risky decision-making (middle and high level vs low level, had odds ratios of 1.62 (1.19 - 2.22) and 3.43 (2.39 - 4.90)) were all the risk factors of adolescent health risk behaviors.</p><p><b>CONCLUSION</b>Adolescents with poor ability of resistance to peer pressure and high risky decision-making were both the risk factors of adolescent health risk behaviors.</p>

<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.

<p><b>OBJECTIVE</b>To explore the status of child neglect among rural areas children aged 0 - 6 years in China.</p><p><b>METHODS</b>A total of 7411 rural children aged 0 - 6 years old who were composed of two age groups (3315 children aged 0 - 2 years old and 4096 children aged 3 - 6 years old) were multistage stratified randomly sampled from 84 villages which were representative of 10 provinces of China, in accordance with sex and age in November 2010. To identify the child neglect based on the Neglect Norms for Children Aged 0 to 2 and 3 to 6 Years Old in Rural Areas of China, SPSS 13.0 was employed for analyzing neglect frequency and degree for every group of different age, sex and neglect type (including physical, emotional, educational, medical, safety and social neglects). χ(2) test and analysis of variance were also used.</p><p><b>RESULTS</b>The degree of child neglect for the children aged 0 - 2 years old was 45.01 ± 7.56, the neglect frequency was 54.9% (1819/3315); the degree of child neglect for the children aged 3 - 6 years old was 44.42 ± 7.57, the neglect frequency was 53.8% (2203/4096). The neglect frequency of children aged 0, 1, 2 years old were 58.5% (654/1117), 52.2% (597/1144), 53.9% (568/1054) (P < 0.05). For children aged 3 - 6 years old, the degrees of emotional and safety neglect for males (44.60 ± 7.86, 36.82 ± 9.03) were higher than females (44.03 ± 7.72, 36.25 ± 9.05) (P < 0.05); and the frequencies of emotional and social neglect for males (16.8% (349/2072), 28.3% (586/2072)) were also higher than females (14.1% (286/2024), 24.8% (503/2024)) (P < 0.05). All children of two age groups suffered neglect mainly on one of the six neglect types (incidences were 20.6% (683/3315) and 22.7% (931/4096)). For 0-2 age groups, the higher neglect frequencies happened in the single-parent family and the remarried family (62.5% (15/24) and 63.2% (12/19)), but for children aged 3 - 6 years old groups, it happened in the single-parent family (60.0%, 27/45).</p><p><b>CONCLUSION</b>Degree and frequency of child neglect among children aged 0 to 6 years old in the rural areas of China are high, and we should find out risk factors and provide efficient prevention measures.</p>

<p><b>OBJECTIVE</b>To develop the national neglect norms for rural children aged 3 to 6 years, which are suitable for Chinese situations.</p><p><b>METHODS</b>According to the multi-stage stratified cluster sampling principle, 84 towns of 10 provinces or municipalities were selected in China. Children aged 3 to 6 years were surveyed in November 2010, the sample of analysis were 3240 (of whom males were 49.6% (1608/3240) and the Han nationality were 93.3% (3023/3240)). Questionnaire was designed by authors and deleted items that did not meet the requirements through several statistical analysis methods, such as item analysis method, factor analysis method, reliability analysis method. The reliability analysis and validity analysis were used to test the stability and reliability of the norm. The evaluation criteria of the scale was determined by the percentile method, then the initial development of the norm completed.</p><p><b>RESULTS</b>After deleting inappropriate items by statistical processing, finally, the scale consisted of 57 items, and included 6 neglected dimensions (physical neglect, emotional neglect, educational neglect, safe neglect, medical neglect and social neglect). Its item loadings ranged from 0.359 to 0.789, which met the statistical requirements. The scale's total Cronbach α coefficients 0.904, the total split-half reliability coefficients were 0.820, the 6 neglect dimensions' Cronbach α coefficients ranged from 0.620 to 0.815, the 6 neglect dimensions' split-half reliability coefficients ranged from -0.034 to 0.789, the scale's parallel reliability were 0.785 and it's re-test reliability were 0.613. After construct validity, external validity and content validity testing, the result showed that this scale could effectively reflect the real neglected status of children investigated. The total neglect cut-off score of this scale were 121.</p><p><b>CONCLUSION</b>The scale has good stability and reliability. And it adapts Chinese conditions and it's convenient to operate.</p>

<p><b>OBJECTIVE</b>The 85th percentile of waist circumference (WC) is considered an appropriate cutoff for Chinese children in the prediction of cardiovascular risks in previous researches, but the risk for hypertension of moderate WC maybe underestimated. The purpose of this study was to understand the characteristics of the WC curve trajectory of children with hypertension and to determine the appropriate cutoffs for waist circumference for Chinese school-age children and adolescents for predicting hypertension risk factors.</p><p><b>METHODS</b>A total of 8194 Han children aged 7 - 17 years were selected from schools in Suzhou, Hefei, and Chizhou cities in Anhui province by stratified cluster sampling. WC and blood pressure were accurately measured in all subjects. LMS (lambda-mu-sigma) method was used to construct WC centile curves. Optimal WC cutoffs were determined by comparing the performance of different percentile sets of WC cutoffs in predicting hypertension risk factors.</p><p><b>RESULTS</b>The fitted LMS curves of WC for the group of boys with hypertension deviate in parallel from that for the corresponding curve in the entire boy study population with higher WC. The WC curves for the group of girls with hypertension gradually upward deviated from the corresponding curve before 12 years of age and then gradually returned to the corresponding curve. WC of boys at the percentiles of 60 was already associated with an increased risk of hypertension and hazard ratio of WC at percentiles of 60, 70, 80, and 90 increased from 1.88(95%CI: 1.18 - 2.99) to 4.87 (95%CI: 3.31 - 7.16). WC of girls at the percentiles of 70 was already associated with an increased risk of hypertension and hazard ratio of WC at percentiles of 70, 80, and 90 increased from 1.71 (95%CI: 1.07 - 2.73) to 3.32 (95%CI: 2.16 - 5.09).</p><p><b>CONCLUSIONS</b>The WC growth trajectory of children with hypertension varies with gender. WC is an independent predictor of childhood hypertension, even when it is well within what is now defined as the normal range of WC. Thus, it is helpful to prevent the risk of cardiovascular disease of children using the parameter that WC cut-off level lower than 85th percentile.</p>
