背景:儿童血压随年龄增长而上升,且与人体测量指标、膳食、运动等许多因素相关,分析儿童血压偏高的有关因素,可为原发性高血压的防治提供科学依据。目的:探讨儿童血压与人体测量指标之间的相关关系。设计:横断面调查。单位:潍坊医学院卫生学教研室。对象:以整群抽样的方法,抽取城区全日制小学三四年级学生1546名,进行体格检查和问卷调查,以资料完整的1508名作为观察对象。方法:用偏相关分析法分析儿童血压与人体测量指标之间的相关关系。主要观察指标:人体测量指标与收缩压和舒张压之间的相关性。结果:①儿童收缩压与性别、年龄、身高、体质量、胸围的Pearson相关系数分别是0.078,0.166,0.337,0.313,0.304,P均<0.01。②儿童舒张压与性别、年龄、身高、体质量、胸围的Pearson相关系数分别是0.047,0.120,0.268,0.271,0.251,P均<0.01。③控制人体测量指标之间的相互影响后,收缩压、舒张压只与身高和胸围呈相关关系(P<0.01),与年龄、性别、体质量无相关关系(P>0.05)。结论:控制人体测量指标之间的相互影响后,儿童的收缩压、舒张压与身高、胸围存在正相关关系。
Background: The blood pressure of children increases with age, and is related to many factors such as body measurement, diet, exercise and so on. Analyzing the relevant factors of children with high blood pressure can provide a scientific basis for the prevention and treatment of essential hypertension. Objective: To explore the correlation between children’s blood pressure and body measurements. Design: Cross-sectional survey. Unit: Weifang Medical College Department of Hygiene. PARTICIPANTS: A total of 1546 students in grade three and four grade primary schools in urban areas were drawn by cluster sampling method. Physical examination and questionnaire survey were conducted. A total of 1508 subjects were selected as observation objects. Methods: Partial correlation analysis was used to analyze the correlation between children’s blood pressure and anthropometric measures. MAIN OUTCOME MEASURES: Correlation between anthropometric measures and systolic and diastolic blood pressure. Results: The children’s systolic blood pressure and sex, age, height, body mass, chest circumference Pearson correlation coefficient were 0.078,0.166,0.337,0.313,0.304, P <0.01. ② The Pearson correlation coefficient of diastolic blood pressure, sex, age, height, body mass and chest circumference were 0.047,0.120,0.268,0.271,0.251, P <0.01 respectively. ③Control systolic blood pressure, diastolic blood pressure only correlated with height and chest circumference (P <0.01), but had no correlation with age, sex and body weight (P> 0.05). Conclusion: There is a positive correlation between systolic blood pressure, diastolic blood pressure and height and chest circumference in children after controlling for the interaction between anthropometric indicators.
