RESUMO
Objective@#To explore the current status related to behavioral problems among children and adolescents aged 12-16 years old in Guizhou Province, China, and to provide a reference for timely prevention and intervention measures.@*Methods@#To capture different economic development levels, a multistage stratified cluster sampling method was used. A total of 3 217 children and adolescents aged 12-16 years old from six middle schools and six primary schools in Guiyang, Duyun, Kaili City from Guizhou Province participated in this study. The Achenbach Child Behavior Checklist (CBCL) and a self designed questionnaire were administered between August and December 2021.@*Results@#The overall detection rate of behavioral problems among the students was 16.60% , and the rate was 14.41% and 18.62% among male and female students, respectively. The results of the Logistic regression analysis showed that good peer relationships ( OR=0.25, 0.16, P <0.05) were associated with a lower risk of behavioral problems in children and adolescents. However, the following factors were associated with an elevated risk of behavioral problems: nonparents as the main caregivers( OR = 1.44 ); children s daily screen time was 1-2 h ( OR =1.47) or more than 2 h( OR =2.75); children who had no sports hobbies( OR = 1.36); father parenting for doting or neglect( OR =1.85, 2.01); maternal parenting for doting( OR = 2.12 ); father had bad life habits( OR =1.69); father and mother were occasionally sick( OR =1.30, 1.38)( P <0.05).@*Conclusion@#Behavioral problems among children and adolescents in Guizhou Province is related to children s unhealthy living habits and various factors in the family environment. It is suggested that families, schools and relevant functional departments give full play to their own advantages and take comprehensive measures to prevent the occurrence of behavioral problems among children and adolescents.
RESUMO
OBJECTIVE: The aim of this retrospective analysis was to determine the age, gender, frequency and distribution of trauma-associated hard tissue and soft tissue lesions of the oral and maxillofacial region in a population from southern Taiwan. PATIENTS AND METHODS: Approximately 10 percent of the 27,995 biopsy records of patients with history of trauma resulting in lesions who were treated at our institution between 1991 and 2006 were examined for this study. RESULTS: In the included records, there were 2,762 soft tissue and 26 hard tissue lesions. Mucocele was the most frequent trauma-associated soft tissue lesion (955 cases). The youngest patients were those who presented with mucocele (mean age = 27.3 years), while the oldest patients were those with peripheral giant cell granuloma (58 years). The lower lip was the most frequent site of occurrence of mucocele (676, 64.5 percent) and was also the predominant site of occurrence of all soft tissue lesions (815, 29.5 percent), followed by the buccal mucosa (654, 23.4 percent) and the tongue (392, 14.2 percent). Trauma-associated hard tissue lesions included only osteoradionecrosis (24 cases) and traumatic bone cysts (2 cases). CONCLUSION: As little data of this nature have been reported from populations of Asian developing countries, the findings of this retrospective analysis is valuable for epidemiological documentation of type of traumatic oral lesions as well as for informing the professionals and the layman about the importance of this category of oral lesions.
