Mortality, morbidity, and risk factors in China and its provinces, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

Problematic smartphone use: A conceptual overview and systematic review of relations with anxiety and depression psychopathology.

For many individuals, excessive smartphone use interferes with everyday life In the present study, we recruited a non-clinical sample of 296 participants for a cross-sectional survey of problematic smartphone use, social and non-social smartphone use, and psychopathology-related constructs including negative affect, fear of negative and positive evaluation, and fear of missing out (FoMO) Results demonstrated that FoMO was most strongly related to both problematic smartphone use and social smartphone use relative to negative affect and fears of negative and positive evaluation, and these relations held when controlling for age and gender Furthermore, FoMO (cross-sectionally) mediated relations between both fear of negative and positive evaluation with both problematic and social smartphone use Theoretical implications are considered with regard to developing problematic smartphone use

Problematic smartphone use and relations with negative affect, fear of missing out, and fear of negative and positive evaluation.

Purpose 
This study investigates the neck/shoulder pain (NSP) and low back pain (LBP) among current high school students in Shanghai and explores the relationship between these pains and their possible influences, including digital products, physical activity, and psychological status


Methods 
An anonymous self-assessment was administered to 3,600 students across 30 high schools in Shanghai This questionnaire examined the prevalence of NSP and LBP and the level of physical activity as well as the use of mobile phones, personal computers (PC) and tablet computers (Tablet) The CES-D (Center for Epidemiological Studies Depression) scale was also included in the survey The survey data were analyzed using the chi-square test, univariate logistic analyses and a multivariate logistic regression model


Results 
Three thousand sixteen valid questionnaires were received including 1,460 (4841%) from male respondents and 1,556 (5159%) from female respondents The high school students in this study showed NSP and LBP rates of 408% and 331%, respectively, and the prevalence of both influenced by the student’s grade, use of digital products, and mental status; these factors affected the rates of NSP and LBP to varying degrees The multivariate logistic regression analysis revealed that Gender, grade, soreness after exercise, PC using habits, tablet use, sitting time after school and academic stress entered the final model of NSP, while the final model of LBP consisted of gender, grade, soreness after exercise, PC using habits, mobile phone use, sitting time after school, academic stress and CES-D score


Conclusions 
High school students in Shanghai showed high prevalence of NSP and LBP that were closely related to multiple factors Appropriate interventions should be implemented to reduce the occurrences of NSP and LBP

Correlational analysis of neck/shoulder pain and low back pain with the use of digital products, physical activity and psychological status among adolescents in Shanghai.

The purpose of this study was to investigate the prevalence of four types of chronic pain (headache, abdominal pain, neck and shoulder pain (NSP), and low back pain (LBP)) and to explore the relationship between the prevalence of chronic pain and self-reported academic pressure in high school students in Shanghai, China. Three thousand students were randomly surveyed on related issues using a questionnaire, and the results were analyzed using a multivariate logistic regression model. Among the 2849 high school students who completed the questionnaire, the overall prevalence rates of headache, abdominal pain, NSP, and LBP were 30.3, 20.9, 32.8, and 41.1 %, respectively. The students in general experienced a heavy burden of learning, a high level of stress, and sleep deprivation, which were closely related to the four types of chronic pain. Chronic pain is a common condition in Chinese adolescents and is closely related to self-reported academic pressure.

A cross sectional study between the prevalence of chronic pain and academic pressure in adolescents in China (Shanghai)

Objective
To explore the incidence of self-reported neck or shoulder pain (NSP) and lower back pain (LBP) among Chinese adolescents in Shanghai and identify the influencing factors for the incidences of NSP and LBP.


Methods
A total of 3 600 students were selected from 30 high schools randomly chosen from 237 regular full-time high schools registered in Shanghai. From each school, 40 students were selected from each of the tenth, eleventh and twelfth grades for a total of 120 students per school. The questionnaire involved questions pertaining to demographic profiles, learning environment and exercise habits of each student. And it also contained questions regarding the amount of weight carried by each student while commuting to and from school, and it was also used to collect specific information related to the occurrence of NSP and LBP. Logistic regression was performed to analyze the potential risk factors for NSP and LBP.


Results
Among 3 600 questionnaires, a total of 2 842 valid ones were returned. The results revealed that the incidence of NSP and LBP in the Chinese adolescent population was 41.1% and 32.8% respectively. Both NSP and LBP were more common in girls than in boys, and 6.3% students reported at least one NSP- or LBP-induced absence from school. A relatively large portion of Chinese adolescents reported experiencing problems such as sedentary behavior (26.7% of the students continued to sit for more than 3 hours after school), a lack of exercise (29.3% exercised less than once each week and 38.2% of students reported that their exercise duration was less than half an hour each time) and overweight backpacks (53.0% complained that their backpack was too heavy). Multivariate logistic regression analysis revealed that gender, grade, physical activity and learning environment were all significantly correlated with the occurrences of NSP and LBP.


Conclusion
The incidences of NSP and LBP are relatively high among adolescents in Shanghai. And several factors, including sedentary behavior, personal exercise habits and backpack weight, influence the occurrencesof NSP and LBP in adolesents.

Objective
To explore the incidence of four types of chronic pain, i. e. headache, abdominal pain, neck & shoulder pain (NSP) and low back pain (LBP) and examine the relationship between the incidence of chronic pain and academic pressure in high school students.


Methods
A total of 3 000 high school students were randomly surveyed with a questionnaire on related issues. And the results were analyzed with a multivariate Logistic regression model.


Results
Among them, 2 849 completed the questionnaire. And the overall incident rates of headache, abdominal pain, NSP, and LBP were 30.3%, 20.9%, 32.8% and 41.1% respectively. The students generally experienced a heavy burden of learning, a high level of stress and sleep deprivation closely related to four types of chronic pain.
