ABSTRACT
The hippocampus is one of the brain regions most vulnerable to inflammatory insults, and the relationships between peripheral inflammation and hippocampal subfields in patients with schizophrenia remain unclear. In this study, forty-six stably medicated patients with schizophrenia and 48 demographically matched healthy controls (HCs) were recruited. The serum levels of IL - 1ß, IL-6, IL-10, and IL-12p70 were measured, and 3D high-resolution T1-weighted magnetic resonance imaging was performed. The IL levels and hippocampal subfield volumes were both compared between patients and HCs. The associations of altered IL levels with hippocampal subfield volumes were assessed in patients. Patients with schizophrenia demonstrated higher serum levels of IL-6 and IL-10 but lower levels of IL-12p70 than HCs. In patients, the levels of IL-6 were positively correlated with the volumes of the left granule cell layer of the dentate gyrus (GCL) and cornu Ammonis (CA) 4, while the levels of IL-10 were negatively correlated with the volumes of those subfields. IL-6 and IL-10 might have antagonistic roles in atrophy of the left GCL and CA4. This suggests a complexity of peripheral cytokine dysregulation and the potential for its selective effects on hippocampal substructures, which might be related to the pathophysiology of schizophrenia.

AIM: Cerebello-cortical functional dysconnectivity plays a key role in the pathology of schizophrenia (SZ). We aimed to investigate the changes in cerebello-cortical directional connectivity in patients with SZ. METHODS: A total of 180 drug-naïve patients with first-episode SZ (54 reassessed after 1 year of treatment) and 166 healthy controls (HCs) were included. Resting-state functional magnetic resonance imaging was used to perform Granger causal analysis, in which each of the nine cerebellar functional systems was defined as a seed. The observed effective connectivity (EC) alterations at baseline were further assessed at follow-up and were associated with changes in psychotic symptom. RESULTS: We observed increased bottom-up EC in first-episode SZ from the cerebellum to the cerebrum (e.g. from the cerebellar attention and cingulo-opercular systems to the bilateral angular gyri, and from the cerebellar cingulo-opercular system to the right inferior frontal gyrus). In contrast, decreased top-down EC in the first-episode SZ was mainly from the cerebrum to the cerebellum (e.g. from the right inferior temporal gyrus, left middle temporal gyrus, left putamen, and right angular gyrus to the cerebellar language system). After 1 year of antipsychotic treatment, information projections from the cerebrum to the cerebellum were partly restored and positively related to symptom remission. CONCLUSION: These findings suggest that decreased top-down EC during the acute phase of SZ may be a state-dependent alteration related to symptoms and medication. However, increased bottom-up EC may reflect a persistent pathological trait.
ABSTRACT
Introduction: The aim of this cross-sectional study was to investigate the association between breakfast patterns and executive function among adolescents in Shanghai, China. Methods: In 2022, we randomly recruited 3,012 adolescents aged 12-13 years from all administrative districts in Shanghai. Breakfast information was collected by parents using a one-day recall method. Executive function was measured using the Behavior Rating Inventory of Executive Function-Parent Version. Latent Class Analysis was performed to identify breakfast patterns based on the food groups in the Diet Quality Questionnaire for China. Results: Breakfast patterns were classified into three categories: "Egg and milk foods", "Grain foods", and "Abundant foods", except for adolescents who skipped breakfast. Logistic regression was used to estimate the multivariate odds ratio (ORs) and 95% confidence intervals (95% CI) for the association between breakfast patterns and potential executive dysfunction. Adolescents in the "Abundant foods" class had a lower risk of executive dysfunction in terms of initiate (OR: 0.36; 95% CI: 0.17-0.76), and organization of materials (OR: 0.18; 95% CI: 0.04-0.94), compared to those who skipped breakfast. Similarly, the breakfast patterns of "Grain foods" and "Egg and milk foods" were associated with a lower risk of executive dysfunction, including initiate and working memory. Discussion: Our findings suggest that breakfast patterns were associated with executive function. The improvement of breakfast patterns among adolescents should be a significant public health intervention.
ABSTRACT
BACKGROUND: Existing research has extensively explored the relationship between government trust and compliance behaviour, but significant controversies exist. Some studies suggest a strong positive correlation between the two. Other studies have found that government trust hinders compliance behaviour. However, during the pandemic, the effectiveness of public health policies largely depends on the public's compliance with these policies. To examine the aforementioned controversies, this study utilizes survey data on the Chinese population during the COVID-19 period to explore the relationship between compliance with public health policies and government trust. METHODS: The study conducted a questionnaire survey of 1,395 individuals from 25 provinces in China from mid-November to mid-December 2022. Firstly, we categorized the public's compliance behaviour with public health policies based on the results of factor analysis. Subsequently, we examined the impact of government trust and professional trust on compliance behaviour with public health policies by constructing a structural equation model. RESULTS: Based on the results of factor analysis, we classified public adherence to public health policies into protective compliance and restrictive compliance. Results from the structural equation model show a positive correlation between the public's trust in the government and both protective and restrictive compliance, with a stronger influence on protective compliance. Government trust also exerts a positive impact on restrictive compliance behaviour through professional trust. Additionally, the study indicates a significant positive correlation between the public's professional trust and restrictive compliance, while it does not significantly affect protective compliance. Moreover, the public from rural areas demonstrates a greater willingness to adhere to both types of public health policies. Married individuals exhibit a stronger inclination toward protective compliance, while females show a stronger tendency toward restrictive compliance. CONCLUSION: The study revealed a significant positive impact of government trust and professional trust on compliance behaviour with public health policies during the COVID-19 pandemic, refuting any negative correlation between government trust and compliance behaviour. Normative motivations for compliance behaviour had a substantial impact on adherence. These findings offer valuable insights for future public health crisis management and public policy formulation.

BACKGROUND: Epigenetic changes are plausible molecular sources of clinical heterogeneity in schizophrenia. A subgroup of schizophrenia patients with elevated inflammatory or immune-dysregulation has been reported by previous studies. However, little is known about epigenetic changes in genes related to immune activation in never-treated first-episode patients with schizophrenia (FES) and its consistency with that in treated long-term ill (LTS) patients. METHODS: In this study, epigenome-wide profiling with a DNA methylation array was applied using blood samples of both FES and LTS patients, as well as their corresponding healthy controls. Non-negative matrix factorization (NMF) and k -means clustering were performed to parse heterogeneity of schizophrenia, and the consistency of subtyping results from two cohorts. was tested. RESULTS: This study identified a subtype of patients in FES participants (47.5%) that exhibited widespread methylation level alterations of genes enriched in immune cell activity and a significantly higher proportion of neutrophils. This clustering of FES patients was validated in LTS patients, with high correspondence in epigenetic and clinical features across two cohorts. CONCLUSIONS: In summary, this study demonstrated a subtype of schizophrenia patients across both FES and LTS cohorts, defined by widespread alterations in methylation profile of genes related to immune function and distinguishing clinical features. This finding illustrates the promise of novel treatment strategies targeting immune dysregulation for a subpopulation of schizophrenia patients.
ABSTRACT
PURPOSE: Surgery for esophageal squamous cell carcinoma (ESCC) is characterized by a poor prognosis and high complication rate, resulting in a heavy symptom burden and poor health-related quality of life (QOL). We evaluated longitudinal patient-reported outcomes (PROs) to analyze the correlations between symptoms and QOL and their changing characteristics during postoperative rehabilitation. METHODS: We investigated patients with ESCC who underwent minimally invasive McKeown esophagectomy at Sichuan Cancer Hospital between April 2019 and December 2019. Longitudinal data of the clinical characteristics and PROs were collected. The MD Anderson Symptom Inventory and European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires were used to assess symptoms and QOL and compare the trajectories of PROs during the investigation. RESULTS: A total of 244 patients with ESCC were enrolled in this study. Regarding QOL, role and emotional functions returned to baseline at 1 month after surgery, and cognitive and social functions returned to baseline at 3 months after surgery. However, physical function and global QOL did not return to baseline at 1 year after surgery. At 7 days and 1, 3, 6, and 12 months after surgery, the main symptoms of the patients were negatively correlated with physical, role, emotional, cognitive, and social functions and the overall health status (P < 0.05). CONCLUSION: Patients with ESCC experience reduced health-related QOL and persisting symptoms after minimally invasive McKeown esophagectomy, but a recovery trend was observed within 1 month. The long-term QOL after esophagectomy is acceptable.

Objective@#To elucidate the association between biorhythm disorders and health risk behaviors in adolescence, so as to provide reference for appropriate interventions.@*Methods@#From March to April 2023, 2 381 adolescents in Shanghai were selected as research objects using convenience sampling and stratified random cluster sampling methods. The Self rating Questionnaire of Biological Rhythm Disorders for Adolescents (SQBRDA) and the self report health risk behaviors questionnaire were used to investigate the status of adolescent biorhythm disorders and nine kinds of health risk behaviors, while a multivariate Logistic regression model was employed to analyze the association between the two variables.@*Results@#The average SQBRDA score was (68.25±0.42) The incidence and detection rates of health risk behaviors in the groups with no co occurrence, mild co occurrence, moderate co occurrence, and severe co occurrence were 234(9.83%), 1 176(49.39%), 830(34.86%) and 141(5.92%), respectively. The total SQBRDA score was positively correlated with the risk of co occurrence of health risk behaviors. The risk of mild co occurrence, moderate co occurrence, and severe co occurrence of health risk behaviors was 9.05 times (95% CI =4.25-19.15, P <0.01), 44.55 times (95% CI =20.75-96.05, P <0.01) and 110.05 times (95% CI =40.65-297.95, P <0.01) higher, respectively, among adolescents with higher scores of biorhythm disorders compared to adolescents with lower scores of biorhythm disorders.@*Conclusions@#Health risk behaviors among adolescents in Shanghai draw attention to a serious phenomenon whereby biorhythm disorders are positively correlated with the risk of co occurrence. Comprehensive interventions aimed at addressing adolescent health risk behaviors should focus on regulating biorhythm disorders.
ABSTRACT
Objective@#To understand the current status and associated factors of comorbidity of common illnesses among primary and middle school students in Shanghai, so as to provide a reference for improving the pathogenic environment and preventing the occurrence of comorbidity of common illnesses.@*Methods@#From September to November 2021, a stratified cluster sampling method was used to select 30 331 middle school students from 112 schools in 16 districts of Shanghai, each with 2 primary schools, 2 junior high schools, 2 high schools and 1 vocational high school. Elementary school students, their health status and influencing factor questionnaires were analyzed.@*Results@#The detection rate of two or more common diseases such as myopia, overweight and obesity, high blood pressure, and abnormal spinal curvature among primary and secondary school students in Shanghai was 38.91%, of which 29.64% of primary and secondary school students had two diseases at the same time, and 9.19% had three diseases, 0.09% had 4 diseases. The detection rate of comorbidity was higher in boys (44.12%) than in girls (33.40%), and higher in junior high school students (40.40%) than in high school students (38.58%) and primary school students (38.01%). The differences were statistically significant (χ2=366.44, 50.33, P<0.01). Multifactor Logistic regression analysis showed that girls sometimes supervise themselves and often remind themselves that their sitting and standing postures were negatively correlated with the common comorbidities of primary and secondary school students (OR=0.64, 0.93, 0.90); junior middle school students and watching TV/d ≥1 h, using computers for ≥1 h/d, and using mobile electronic devices for >1 h/d were positively correlated with the comorbidity of common diseases among primary and secondary school students (OR=1.07, 1.10, 1.06, 1.10) (P<0.05).@*Conclusions@#The prevalence of comorbidity of common illnesses among primary and middle school students in Shanghai is not optimistic, which might be associated with combined effects of various external environmental factors. Targeted intervention should be implemented to effectively prevent the occurrence of comorbidities among students.

Objective@#To investigate incidence of traffic injury and its associated factors among secondary school students in Shanghai, so as to provide scientific basis for intervention.@*Methods@#Using the method of multi stage stratified random cluster sampling, an on-the-spot anonymous questionnaire survey was conducted among 19 629 adolescents from 16 districts in Shanghai from May to June 2021. The multivariate Logistic regression was used to analyze possible associated factors.@*Results@#The rate of road traffic injuries among secondary school students in Shanghai was 0.74%, the highest reporting rate among secondary vocational school students (1.35%), followed by junior high school students (0.72%), and the lowest reporting rate of road traffic injuries among senior high school students (0.55%), with statistically significant differences ( χ 2=13.39, P <0.01). The results of multivariate Logistic regression analysis showed that the junior high school ( OR =0.56, 95% CI =0.35-0.89) or senior high school ( OR = 0.40 , 95% CI =0.24-0.68) and residential school ( OR =0.39, 95% CI =0.18-0.88) were protective factors of road traffic injuries( P <0.05). Male ( OR =1.65, 95% CI =1.14-2.37), unaware of seat belt ( OR =6.38, 95% CI =2.81-14.50), had a cycling chase/fight ( OR =2.33, 95% CI =1.39-3.90), music or phone calls on a bicycle ( OR =2.54, 95% CI =1.72-3.75) were positively correlated with road traffic injury( P <0.05).@*Conclusions@#The road traffic injury among secondary school students in Shanghai is related to many factors, and traffic hazards are common among students in all school sections. Targeted measures should be taken to strengthen traffic safety knowledge education and intervention in healthy behaviors among adolescents, in order to reduce the incidence of road traffic injury.
ABSTRACT
Objective@#To understand the prevalence and trend of diet related behaviors among secondary school students in Shanghai, and to provide a scientific basis for developing appropriate health education strategies.@*Methods@#Anonymous questionnaire surveys were conducted among 71 291 students selected by multi stage stratified cluster sampling method from junior high schools,senior high schools and vocational schools in Shanghai in the year of 2008,2012,2015,2017,2019. The questionnaire adopted was "Shanghai adolescent health related behavior questionnaire". Test for trend test were applied for the analysis of the prevalence of their dietary behaviors.@*Results@#The proportion of middle school students nutritional status within the normal range in each survey year were 73.40 %, 72.60%, 68.06%, 68.73%, 67.53%, respectively, while the rate of overweight and obesity increased from 13.17% in 2008 to 23.73% in 2019. The proportion of "eating fried food" decreased significantly by year, from 12.05 % to 4.23% (male, APC=-7.94%, t =-4.33, female, APC= -9.29%, t=-7.71, P <0.05) respectively. And the proportion of "eating dessert" also decreased significantly by year, from 31.66% to 11.14% (male, APC=-8.41%, t =-6.37, female, APC=-8.67%, t=-6.96, P <0.05). In the five surveys, the percentages of healthy diet related behaviors of secondary school students were 12.81%-21.82%, no significant upward trend was observed in the whole( P >0.05). The proportion of diet-related behaviors of nutrition unbalance and easily leading to obesity decreased significantly from 35.47% to 17.00%(APC=-6.71%, t= -5.00 , P <0.05). The proportion of diet related behavior of nutrition unbalance and not easily leading to obesity increased significantly from 39.15% to 60.16%(APC=3.46%, t=6.18, P <0.05).@*Conclusion@#Overweight and obesity among secondary school students in Shanghai are increasing during the past decade, and the proportion of healthy dietary behaviors is low. The knowledge of rational diet should be publicized among these students in order to develop healthy dietary behaviors.
ABSTRACT
Objective@#To understand the prevalence and influencing factors of scoliosis among primary and middle school students in Shanghai, so as to provide reference for the prevention and control strategies of scoliosis in children and adolescents.@*Methods@#From September to December 2021, a total of 4 531 students from grade four of primary school to grade three of junior high school from 16 primary and middle schools in 4 districts of Shanghai were selected by multi stage stratified cluster sampling to carry out scoliosis screening and questionnaire survey. Independent sample t-test, Chi-squared test, Fisher s exact probability method and nonparametric Mann Whitney U-test were used for statistical analysis, and multivariate Logistic regression was used to analyze the influencing factors of scoliosis.@*Results@#The on the spot detection rate of scoliosis abnormality was 7.4% and the prevalence was 2.2%, mainly for thoracolumbar scoliosis (60.4%) and the scoliosis angle of 10° -<20°(88.1%). The results showed that the detection rate of scoliosis in boys was 1.6% and in girls was 3.3%, with a statistically significant difference ( χ 2=11.84, P < 0.01). There were significant differences in weight and BMI between scoliosis students and students with negative initial screening( t = -3.77, -5.30, P <0.01). And there was a statistically significant difference in the detection rate of scoliosis with different frequency of classroom seating arrangements ( Z =2.02, P <0.05). The results of multivariate Logistic regression showed that the risk of scoliosis in girls was higher than that in boys ( OR =1.87, 95% CI =1.21-2.88). BMI ( OR =0.89, 95% CI =0.83-0.95) and frequency of classroom seating arrangements ( OR =0.49, 95% CI =0.25-0.93) were correlated with lower rate of scoliosis. After stratification by sex, the frequency of classroom seating arrangements ( OR =0.26, 95% CI =0.10-0.67) in boys and the educational stage ( OR =2.35, 95% CI =1.26-4.41) in girls ( P <0.05) was correlated with higher rate of scoliosis, while BMI ( OR =0.86, 95% CI =0.79-0.94) in girls were correlated with lower rate of scoliosis.@*Conclusion@#Regular screening of scoliosis is an effective method for early detection of scoliosis. Girls in junior high school and low BMI should be paid close attention to. According to the occurrence and influencing factors of scoliosis, comprehensive prevention and control based on family, school, society, and other aspects can be carried out.
ABSTRACT
Objective@#To explore the patterns of health risk behaviors among secondary school students in Shanghai, so as to provide a basis for implementing targeted interventions.@*Methods@#From May to June 2021, 21 junior high schools, regular high schools and secondary vocational schools were selected from Shanghai, and the occurrence of dangerous health behaviors of 6 092 students were investigated in the form of self-filled questionnaires. The clustering analysis of the sample was performed by Ward s departure and peace method.@*Results@#Three types of clustering characteristics were found in this study: being bullied, depression (64.9%), loneliness (48.2%), and insomnia (42.4%) in the high-risk group (1 004, 16.5%); excessive video games (53.1%) and sugary drinks (89.3%) and fried food intake (79.0%) in the medium-risk group (1 585, 26.0%); the low-risk group (3 503, 57.5%) was characterized by extremely low alcohol consumption (0) and smoking (0.4%). The reporting rate on sugary beverage intake, fried food intake, physical activity, malicious teased, solicited, isolated/intentionally excluded, outside the group activities, threatened, kicked/hit/pushed/locked in house, smoking, unhealthy weight loss, playing video game overtime were statistically significant among the three groups ( χ 2=36.74, 41.85, 30.07, 652.68, 334.40, 669.89, 358.84, 233.12, 101.46, 88.45, 230.15, P <0.01) .The difference in reporting rates of loneliness, depression, insomnia and drinking were significant among the three groups (Fisher s test, P <0.01). The majority of junior high school students, general high school students and girls in the high-risk group; boys, general high school students and junior high school students in the excessive video game and unhealthy diet group.@*Conclusion@#There are clusters of health-related risk behaviors among secondary school students in Shanghai, focusing on two major aspects: poor lifestyle and mental health. Targeted interventions should be implemented according to the characteristics of health-related risk behaviors clustering to enhance the intervention effect.
ABSTRACT
Objective@#To understand the status of teaching environmental health in primary and secondary schools and explore its association with myopia, so as to provide a basis for precision myopia prevention and control.@*Methods@#From September to October 2020, a stratified cluster sampling method was used in 16 districts of Shanghai. After matching the teaching environment testing classrooms with the classrooms where the students were surveyed, totally 470 classrooms and 14 624 students were monitored. Trained professional technicians used laser range finder, luxmeter to measure parameters about teaching environmental health. Students were subject vision testing and questionnaires. Multilevel models was used to analyze the association between teaching environment and screening myopia.@*Results@#The qualified rates of each indicators of teaching environmental health were as follows: window to floor area ratio (93.0%), classroom area per capita (82.1%), uniformity ratio of illuminance of blackboard ( 79.7% ), blackboard size (68.7%), daylight factor (67.0%), blackboard hanging height (66.9%), average illuminance on desk (66.4%), uniformity ratio of illuminance of desk (63.6%), reflectance of blackboard (46.8%), average illuminance on blackboard (41.4%), reflectance of wall (33.2%), desk and chair allocation compliance rate (19.8%). The results of two level Logistic model analysis showed that unqualified average illuminance on blackboard was positively associated with screening myopia ( OR =1.24, 95% CI = 1.05 -1.47, P <0.05).@*Conclusion@#Teaching environmental health of primary and secondary schools in Shanghai is not optimistic, teaching environment especially the desk and chair allocation compliance rate need to be improved. The average illumination on blackboard is positively correlated with screening myopia, suggesting that myopia prevention and control can focus on improving the illuminance on blackboard.
ABSTRACT
Objective@#To explore the effectiveness of preventive treatment for latent tuberculosis infection (LTBI) patients, so as to provide reference for the management and preventive treatment of clustered epidemic in schools.@*Methods@#Data came from the school tuberculosis outbreak of a boarding high school in Kaizhou District, Chongqing, which occurred between June 2017 and March 2018 among 2016 grade high school teachers and students for investigation and analysis. The total incidence, LTBI patients, and the incidence after preventive treatment for 5 years were followed up.@*Results@#A total of 34 cases of pulmonary tuberculosis from June 2017 to March 2018. A total of 1 357 individuals were screened for 6 concentrated contact screenings, with a confirmed tuberculosis rate of 2.43%, a tuberculosis skin test (TST) positive rate of 27.41%, and a strong TST positive rate of 7.39%. Among them, the confirmed tuberculosis rate and TST positive rate in the first case class were much higher than those in other classes, with statistically significant differences ( χ 2=286.30, 98.59, P <0.01). 88 cases of LTBI were found, with 31 cases receiving preventive treatment (35.23%), of which 28 completed preventive treatment (90.32%). After five years of follow-up, 73 cases of pulmonary tuberculosis were diagnosed in 2016 by the school senior high school, with a incidence rate of 0.98/10 2 (person/person years). Fifteen of the 88 LTBI patients were diagnosed with pulmonary tuberculosis, and the incidence rate was 3.33/10 2 (person/person years). The incidence rate of the preventive treatment group was 0.7/10 2 (person/person years)lower than that of the medical observation group 4.5/10 2 (person/person years), with a statistically significant difference ( χ 2=4.31, P <0.05).@*Conclusion@#The classes with higher TST positive rate and strong positive rate have higher incidence rate. Improving the preventive treatment rate of LTBI patients can effectively reduce the incidence rate of tuberculosis.
ABSTRACT
Objective@#To investigate the establishment of health care institutions and the staffing primary and secondary school health care in Shanghai, and to understand the capacity building needs of health care personnel.@*Methods@#A survey was conducted on all primary and secondary schools in Shanghai from April to August in 2020. The content of the questionnaire covers the establishment of health care institutions, the staffing of school health care centers and the capacity building need of health care personnel. Chi square test was used to compare the difference of the health care institutions setting and staffing by schools and areas.@*Results@#In 2020, there were 1 847 primary and secondary schools in Shanghai (including branches schools). About 51.4% of primary and secondary schools in Shanghai were equipped with school health care personnel in the ratio of the number of students at least 600∶1 , and the staffing compliance rate of urban schools (59.3%) was higher than that of suburban schools (47.3%)( χ 2=24.27, P <0.01). All school health care personnel believed that there are currently few opportunities for capacity buliding services from health facilities.@*Conclusion@#School health care institutions in Shanghai are well equipped, but the staffing shortage is substantial, with strong need for capacity building.
ABSTRACT
Objective@#To analyze the trends of smoking and drinking behaviors among adolescents in Shanghai from 2004 to 2019, and to provide theoretical evidence for effective tobacco and alcohol interventions among adolescents.@*Methods@#Data regarding smoking and drinking behaviors from adolescent health risk behavior surveillance program in Shanghai from 2004 to 2019 were collected, and the prevalence of ever smoking, current smoking, ever drinking and current drinking were comparatively analyzed.@*Results@#The prevalence of ever smoking, current smoking, ever drinking and current drinking among boys were significantly higher than those among girls in 2004 to 2019( χ 2=58.20-347.44, P <0.01). Except the prevalence of ever drinking in 2012, the prevalence of ever smoking, current smoking, ever drinking and current drinking in vocational school students were the highest in each survey( χ 2=111.19-1 196.61, P <0.01). From 2004 to 2019, the standardized rates of smoking and drinking of boys and girls showed a downward trend ( APC =-6.20--1.80, P <0.05). The standardized ever smoking rate and the standardized ever drinking rate of both boys and girls declined significantly from 2004 to 2019( APC=-5.00, -1.80, P <0.05). The overall standardized rate of ever smoking decreased from 21.02% in 2004 to 12.23% in 2019, and that of ever drinking decreased from 60.52% in 2004 to 47.17 % in 2019). However, the overall standardized rates of current smoking and current drinking did not reach statistically significance( P >0.05).@*Conclusion@#From 2014 to 2019,the prevalence of ever smoking and ever drinking among adolescents in Shanghai over the observed period showed a declining trend by years, but there was no significant change in current smoking and current drinking among adolescents. Specific interventions targeting on smoking and drinking behaviors among adolescents need to be strengthened.
ABSTRACT
Objective@#To analyze the trend of adolescent health risk behaviors in Shanghai, and to provide reference for the comprehensive intervention of middle school students health risk behaviors.@*Methods@#Based on the health risk behavior questionnaire of Chinese Center for Disease Control and Prevention, the questionnaire was adapted according to the actual monitoring needs.
