Evaluating the accessibility and capacity of SARS-CoV-2 vaccination and analyzing convenience-related factors during the Omicron variant epidemic in Beijing, China.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination service system lacks standardized indicators to assess resource allocation. Moreover, data on specific vaccination-promoting measures is limited. This study aimed to evaluate vaccination accessibility and capacity and investigate convenience-related factors in China during the Omicron variant epidemic. We collected information on SARS-CoV-2 vaccination services among vaccination sites in Beijing. Analysis was performed using nearest neighbor, Ripley's K, hot spot analysis, and generalized estimating equations. Overall, 299 vaccination sites were included. The demand for the SARS-CoV-2 vaccine increased with the increase in daily new cases, and the number of staff administering vaccines should be increased in urban areas at the beginning of the epidemic. Providing vaccination for both children and adults, extending vaccination service hours, and offering a wider range of vaccine categories significantly increased the doses of vaccines administered (all P < .05). The provision of mobile vaccination vehicles effectively increased the doses of vaccines administered to individuals aged ≥ 60 years (P < .05). The allocation of SARS-CoV-2 vaccination services should be adjusted according to geographic location, population size, and vaccination demands. Simultaneous provision of vaccination services for children and their guardians, flexible service hours, prompt innovative vaccine production, and tailored vaccination strategies can foster vaccination uptake.

[Prevalence of deliberate self-harm and its relation with suicidal behaviors among students in middle schools in Beijing].

OBJECTIVE: To understand the prevalence of deliberate self-harm in middle school students in Beijing, and explore the relationship between self-harm and suicidal behaviors. METHODS: An anonymous self-administered questionnaire survey was conducted among 5 807 students selected through cluster random sampling from grade 9 to grade 12 in 16 middle schools in Beijing. RESULTS: Among the surveyed middle school students, 35.6% reported that they once had self-harm behaviors, 7.0% reported often had self-harm behaviors in the past 30 days before the survey. More girls reported self-harm behaviors than boys did. And the prevalence of self-harm behaviors was highest in girls in grade 8 and in boys in grade 9. The students in key senior high schools, or living with single or remarried parents were the risk population to have self-harm behaviors. Higher suicide behavior reporting rate was correlated with higher self-harm behavior reporting rate. Compared with students who reported no self-harm behaviors during the past month, the suicide behavior reporting rate in students reporting self-harm behaviors increased by 5.7-12.3 times. CONCLUSION: Deliberate self-harm behaviors were associated with suicide behaviors among middle school students in Beijing. Early psychological intervention and life education should be carried out among middle school students in order to find risk population and save their life.

[Prevalence and associated factors of school physical violence behaviors among middle school students in Beijing].

OBJECTIVE: To described the prevalence of school physical violence behaviors and to explore its associated factors among middle school students in Beijing. METHODS: In 2009, a randomly selected cross-sectional survey was conducted among 5718 students in grades 7 to 12 in Beijing. A self-report anonymous questionnaire involving physical violence at school and socio-demographic variables, such as sex, grades, family economic status and family structure, peer relationships, and communication with their parents etc. were completed by students themselves. Logistic regression was used to estimate the association between physical violence and socio-demographic variables. RESULTS: Among the students, 14.3% reported that they had had physical violence behavior in school during the past 12 months. Male students had been more likely to have physical violence behaviors than female students (Male 25.2%, Female 5.1%). For both male and female students, poor school cohesion were the risk factors of physical violence behaviors (Male OR = 1.060, Female OR = 1.065). For male students, factors as father's lower education level (OR = 1.653), remarried/single-parent families (OR = 1.834), low-grade (grade 7 OR = 5.291; grade 11 OR = 1.526), poor school performance (OR = 1.470) etc were the risk factors of physical violence behaviors; while better-off family economic status (OR = 0.546), good peer relationships (OR = 0.618), and easy to communicate with the father (OR = 0.756) were the protective factors of physical violence behaviors. For female students, easy to communicate with her mother (OR = 0.358) were the protective factors of physical violence behaviors. CONCLUSION: For male and female students, the prevalence of school physical violence and its related factors were different. Actions on prevention against physical violence behaviors should be fully considered, including factors as gender, personal characteristics, family, school and peers etc.
