BACKGROUND: Using the Chinese version of the Global School‐based Health Survey (GSHS), this article describes the prevalence of being bullied among a nationally representative sample of Chinese students in grades 6‐10 and explores the relationships between being bullied and selected indicators of psychosocial adjustment. METHODS: A total of 9015 students in middle schools in Beijing, Hangzhou, Wuhan, and Urumqi completed the Chinese version of the GSHS. Researchers analyzed the results from 2 questions about the frequency and form of being bullied and 11 questions about psychosocial adjustment. Descriptive statistics and logistic regression were used in the analysis. RESULTS: About 25.7% of middle school students reported being bullied on 1 or more of the past 30 days. Rates of being bullied were similar for males and females, but the forms of being bullied were different. Being bullied was significantly lower in Beijing than in the other 3 cities. There were significant psychosocial differences between students who had been bullied and students who had not been bullied. Students who had been involved in a physical fight, often felt lonely, or had considered suicide in the past 30 days were more likely to report being bullied. Students who thought that other students in their school were often kind and helpful, who felt parents often understood their troubles, or who were taught in school how to handle stress were less likely to report being bullied. Conclusions: Being bullied is not uncommon in Chinese middle schools. Chinese schools typically place great emphasis on academic achievement, perhaps at the expense of the social climate of the school. Results indicated schools could implement changes to the school climate to reduce the likelihood of students' being bullied.
Background: China's socioeconomic and population structures have evolved markedly during the past few decades, and consequently, monitoring the prevalence of Parkinson's disease (PD) is crucial.Objective: This study aimed to investigate the prevalence of PD within Chinese communities, particularly in older people.
One of the most important predictors of preterm births (PTBs) or low-birth-weight births (LBWBs) is whether a mother has had a history of these birth outcomes. This study examined how different characterizations of birth history (e.g., any previous incidence of PTBs or LBWBs, immediate previous birth that was preterm or of low birth weight, and number of previous PTBs or LBWBs) were associated with PTBs or LBWBs. Based on birth records (n = 98,776) reported to the vital statistics electronic registration system in Nebraska from 2005 to 2014, mothers with a history of PTBs or LBWBs were more likely to have recurrences of these outcomes than those who did not have any history of PTBs or LBWBs. The adjusted odds ratios for recurrent PTBs ranged from 2.82 (95% CI: 2.62, 3.04) to 5.54 (95% CI: 4.67, 6.57) depending on how previous incidence of PTBs or LBWBs were characterized. The corresponding adjusted odds ratio for LBWBs ranged from 1.58 (95% CI: 1.43, 1.74) to 6.75 (95% CI: 4.96, 9.17). Relative to other measures used to characterize birth history, the use of number of previous PTBs or LBWBs allows for identifying mothers most vulnerable to recurrences of these birth outcomes. To help identify mothers at risk for future PTBs or LBWBs, it is beneficial to develop state-wide surveillance of reoccurrences for adverse birth outcomes which is feasible by integrating all separated birth records for the same mother using vital statistics data.
BackgroundDespite evidence that motorcycle helmets reduce morbidity and mortality, helmet laws and rates of helmet use vary by state in the U.S.MethodsWe pooled data from eleven states: five with universal laws requiring all motorcyclists to wear a helmet, and six with partial laws requiring only a subset of motorcyclists to wear a helmet. Data were combined in the Crash Outcome Data Evaluation System’s General Use Model and included motorcycle crash records probabilistically linked to emergency department and inpatient discharges for years 2005-2008. Medical outcomes were compared between partial and universal helmet law settings. We estimated adjusted relative risks (RR) and 95 % confidence intervals (CIs) for head, facial, traumatic brain, and moderate to severe head/facial injuries associated with helmet use within each helmet law setting using generalized log-binomial regression.ResultsReported helmet use was higher in universal law states (88 % vs. 42 %). Median charges, adjusted for inflation and differences in state-incomes, were higher in partial law states (emergency department $1987 vs. $1443; inpatient $31,506 vs. $25,949). Injuries to the head and face, including traumatic brain injuries, were more common in partial law states. Effectiveness estimates of helmet use were higher in partial law states (adjusted-RR (CI) of head injury: 2.1 (1.9-2.2) partial law single vehicle; 1.4 (1.2, 1.6) universal law single vehicle; 1.8 (1.6-2.0) partial law multi-vehicle; 1.2 (1.1-1.4) universal law multi-vehicle).ConclusionsMedical charges and rates of head, facial, and brain injuries among motorcyclists were lower in universal law states. Helmets were effective in reducing injury in both helmet law settings; lower effectiveness estimates were observed in universal law states.
Objective -This study examines differences in Chinese high school students' alcohol expectancies by drinking status (nondrinker, occasional drinker, regular drinker) and gender (male, female). Method -The authors administered the Chinese Adolescent Alcohol Expectancy Questionnaire (CAEQ) to a convenience sample of 1244 high school students (M = 627; F = 617) from schools in Hohhot City and Tongliao City in Inner Mongolia, China. Results -Differences were found in the 8 CAEQ factors (3 negative and 5 positive factors). Regular drinkers had lower negative consequences and higher positive perception expectancies than nondrinkers or occasional drinkers. Nondrinkers had higher harm to person/reputation expectancies than occasional or regular drinkers. Occasional drinkers had higher beneficial/moderation and lower harm to person/reputation expectancies than nondrinkers. Boys had higher positive perception expectancies than girls. Conclusion -Expectancies are associated with Chinese adolescents' drinking. Identifying the characteristics of alcohol consuming youth can inform the development of prevention interventions and alcohol policies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
