Objective: To describe the baseline characteristics of School-based Cardiovascular and Bone Health Promotion Program(SCVBH) in Beijing. Methods: Children and adolescents were selected in 30 schools (8 primary schools, 21 middle schools and one 12-year education school) from Dongcheng, Tongzhou, Fangshan and Miyun districts of Beijing by using a stratified cluster sampling method. 15 391 students in grade 1 to 4 from primary schools, grade 1 from junior and senior high schools were enrolled in the investigation with an exclusion of students who were not able to participate due to trauma or other uncomfortable physical conditions. The baseline survey including a questionnaire survey, physical examination and blood biochemical test was conducted from September 2017 to January 2018. Obesity, blood pressure, fasting blood glucose, lipid, bone density and grip were evaluated. Results: The prevalence of obesity, hypertension, hyperglycemia (impaired fasting glucose and diabetes), dyslipidemia, lower bone density were 22.3%(3 394), 14.8%(2 248), 10.4%(1 490), 20.3%(2 919) and 2.1%(316) in total respectively, and 27.2%(2 081), 16.3%(1 244), 12.8%(922), 22.2%(1 595) and 1.2%(94) for boys, 17.3%(1 313), 13.3% (1 004), 7.9%(568), 18.4%(1 324) and 2.9%(229) for girls. Boys had higher prevalence of obesity, hypertension, hyperglycemia, and dyslipidemia and lower prevalence of low bone density than girls (all P values <0.05) The mean of body mass index, systolic blood pressure, fasting plasma glucose and grip of boys were significantly higher than that of girls (all P values <0.05).The mean of body mass index, systolic blood pressure, fasting plasma glucose and grip of boys were significantly higher than that of girls (all P values <0.05), the mean of fat mass percentage, total cholesterol, triglyceride, high density lipoprotein-cholesterol and low density lipoprotein-cholesterol of boys were significantly lower than those of girls (all P values <0.05). Conclusion: The prevalence of risk factors of chronic cardiovascular disease was high and the low bone density was appearing in children and adolescents in this study. The promotion of cardiovascular and bone health should be implemented in children and adolescents.
目的： 描述儿童青少年心血管与骨健康促进项目基线特征。 方法： 2016年采用分层整群抽样方法，选择北京市东城、房山、密云及通州区的30所学校（包括8所小学21所中学和1所12年制学校），排除因外伤等身体不适不能参加体检者，将1~4年级、初中一年级和高中一年级的学生作为研究对象，共15 391名。进行问卷调查、体格检查、生化指标检测等基线调查，评价儿童青少年肥胖、血压、血糖、血脂和骨密度及握力情况。 结果： 肥胖、高血压、高血糖、血脂异常和骨密度减低检出率分别为22.3%（3 394例）、14.8%（2 248例）、10.4%（1 490例）、20.3%（2 919例）和2.1%（316例），男生分别为27.2%（2 081例）、16.3%（1 244例）、12.8%（922例）、22.2%（1 595例）和1.2%（94例），女生分别为17.3%（1 313例）、13.3%（1 004例）、7.9%（568例）、18.4%（1 324例）和2.9%（229例）。男生肥胖、高血压、高血糖和血脂异常检出率均高于女生，骨密度减低检出率低于女生，P值均<0.05。男生BMI、收缩压、空腹血糖和握力均高于女生（P<0.05），体脂百分比、总胆固醇、甘油三酯、HDL-C和低LDL-C均低于女生（P<0.05）。 结论： 儿童青少年心血管慢性病危险因素呈现高发态势，并已经出现骨密度减低问题，心血管与骨健康促进需要从儿童青少年期开展。.
