摘要
目的:利用多水平模型分析儿童青少年超重、肥胖对其身体机能的影响,为客观认识其影响提供依据。方法:利用2005年中国学生体质与健康调研数据资料,依据中国肥胖问题工作组制定的《中国学龄儿童青少年超重、肥胖BMI筛查分类标准》,筛查超重、肥胖儿童青少年,以肥胖人数为基数,按性别、城乡频数匹配(1∶1∶1)随机抽取超重和非超重个体,采用单因变量和多因变量多水平模型,综合分析儿童青少年超重、肥胖对其身体机能的影响。结果:单因变量模型分析结果显示,超重儿童青少年收缩压、舒张压比非超重者平均增加5.25 mmHg和3.44mmHg(1 mmHg=0.133 kPa),差异有统计学意义(P<0.01),但脉搏、肺活量差异无统计学意义(P>0.05);肥胖儿童青少年收缩压、舒张压、脉搏和肺活量比非超重者平均增加10.15 mmHg、6.34 mmHg、1.44次/分和390.04mL,差异有统计学意义(P<0.01)。多因变量模型分析结果显示,超重儿童青少年收缩压、舒张压、脉搏、肺活量均比非超重者高,差异均有统计学意义(P<0.05);肥胖儿童青少年收缩压、舒张压、脉搏比非超重者高,差异有统计学意义(P<0.01),但肺活量差异无统计学意义(P>0.05)。结论:儿童青少年超重、肥胖可导致其身体机能下降,肥胖造成的影响更加明显。
Objective:To analyze the influence of overweight and obesity on body function among children and adolescents using a multilevel model, and to provide the basis for understanding their influence. Methods: According to the "Reference Norms for Screening Overweight and Obesity in Chinese Children and Adolescents" set up by Working Group Obesity in China (WGOC) in 2003, we screened out indi- viduals with overweight and obesity from the data obtained from the body and health survey of Chinese children and adolescents in 2005. The samples of the non-overweight group and the overweight group were randomly selected from the screened data by 1:1 match with samples of the obesity group by gender and city/rural area, then underwent the multilevel model to explore the influence of overweight and obesi- ty on body function. Results: The single dependent variable model showed that the overweight group had significant increases in systolic blood pressure (SBP) and diastolic blood pressure (DBP) by 5.25 mmHg ( 1 mmHg = 0. 133 kPa) and 3.44 mmHg , respectively ( P 〈 0.01 ), when compared with the non-overweight group. There were no significant differences between the overweight and non-overweight groups in pulse and vital capacity (VC) (P 〉 0.05 ), and the obesity group had significant increases in SBP, DBP, pulse and VC by 10. 15 mmHg, 6.34 mmHg, 1.44 times/rain and 390.04 mL, respectively (P 〈 0.01 ), when compared with the non-overweight group. The multiple dependent variables model showed that the SBP, DBP and pulse of the overweigh group and obesity group were significantly greater than those of non-overweight group ( P 〈 0.01 ). There was a significant difference between the over- weight group and non-overweight group in VC (P 〈 0.05 ), yet the same result was not found between the obesity group and non-overweight group (P 〉 0.05 ). Conclusion: Overweight and obesity may cause a decline in body function among children and adolescents, and obesity has a mo
