曲靖市儿童超声骨密度现状调查及影响因素分析
Investigation of bone mineral density and analysis of influencing factors in children in Qujing City
摘要
Abstract
Objective This paper aims to understand the status of bone mineral density(BMD)in children and adolescents in Qujing City,and analyze the influencing factors of insufficient BMD,in order to provide a theoretical basis for promoting bone health in chil-dren and adolescents in Qujing City and preventing and treating insufficient BMD in this region.Methods A total of 1,312 students aged 2-12 years from one urban and one rural primary school and kindergarten in Qujing City were selected for physical examinations,questionnaire surveys,and BMD measurements from August to September 2023.BMD measurements were performed using the Bei-jing Yuerui Pediatric Bone Density Detector(model:BMD-PM3).The midshaft of the left tibia was measured for children under 3 years old,and the distal radius of the left hand was measured for children over 3 years old.A self-designed questionnaire was used to investigate general information about the children,family birth and feeding conditions,dietary habits,sleep,electronic screen time,and outdoor activities.A total of 1,278 students with the complete questionnaire and BMD measurement information were included in the statistical analysis of this study.Data entry was performed using the Epidata 3.1 software,and statistical analysis was conducted using SPSS 26.0 software.Results Among the 1,278 children aged 2-12 years included in the statistical analysis,644 had insuffi-cient BMD,accounting for 50.39％.Factors that influenced BMD levels in children at different age stages included height,body weight,body mass index(BMI),mother's education level,place of residence,gestational weeks at birth,frequency of dairy product intake,frequency of snack intake,timely supplementation of vitamin D,and outdoor activity time.No association was found between gender,mode of delivery at birth,birth weight,feeding method,sleep duration,electronic screen time,and BMD levels.Conclusion Ensuring the intake of milk and dairy products,timely supplementation of vitamin D,increasing outdoor activity time,and reducing snack intake are beneficial for increasing BMD in children and adolescents.关键词
