摘要

目的:应用阻抗法和氧化氘稀释法(D2O)评价儿童体重指数(BMI)与脂肪量的关系。方法:对156名8 ~ 11岁小学生进行调查。孩子们接受了关于生活方式和饮食习惯的询问。采用阻抗法和D2O技术测定体成分。结果:BMIZ法、生物电阻抗法和D2O法分别占30.1%、14.7%和42.9%，差异有统计学意义。尽管后两种分类之间存在差异，但我们发现阻抗测定法和d20技术测定的体脂百分比之间存在显著相关性(r = 0.695, p<0.01)。与D2O技术相比，生物电阻抗分析在总体儿童中低估了%BF，在男孩中低估了70.05%，在女孩中低估了84.73%。结论:这项研究表明，超重和肥胖的比例因使用的方法而异。需要进一步发展儿童的身体组成方法，以真正确定肥胖的患病率，从而更好地监测这一公共卫生问题。关键词:体重指数;身体脂肪;氘同位素稀释;impedancemetry;肥胖。

Relationship of body mass index to percent body fat determined by deuterium isotopic dilution and impedancemetry among Tunisian schoolchildren

Objectives: This study aims to evaluate the relation of body mass index (BMI) to fat mass among children by two techniquesimpedancemetry and deuterium oxide dilution (D2O). Methods: This study was carried out in 156 schoolchildren aged between 8 and 11 years. The children received interrogationspecifying lifestyle and food habits. Body composition was determined using the impedancemetry and D2O technique. Results: The results showed a difference between the percentage of obese and overweight children according to BMIZ classification(30.1%), bioelectrical impedance method (14.7%) and D2O technique (42.9%). Despite the difference between the lasttwo classifications, we found a significant correlation between body fat percentages determined by impedancemetry and D2Otechnique (r = 0.695, p<0.01). Bioelectrical impedance analysis underestimated %BF by 78.02% in overall children, by 70.05%in boys and by 84.73% in girls compared to D2O technique. Conclusion: This study has demonstrated that the percentage of overweight and obesity varied according the methods used.Further development of body composition methods is needed in children for the real determination of the obesity prevalenceand therefore a better monitoring of this public health problem. Keywords: BMI; body fat; deuterium isotopic dilution; impedancemetry; obesity.

期刊介绍： The African Health Sciences is an internationally refereed journal publishing original articles on research, clinical practice, public health, policy, planning, implementation and evaluation, in the health and related sciences relevant to Africa and the tropics. Its objectives are to: Advocate for and promote the growth of reading culture in sub Saharan Africa; Provide a high quality journal in which health and policy and other researchers and practitioners in the region can and world wide, can publish their work; Promote relevant health system research and publication in the region including alternative means of health care financing, the burden of and solution of health problems in marginalized urban and rural communities amongst the displaced and others affected by conflict; Promote research and the systematic collection and collation and publication of data on diseases and conditions of equity and influence; Promote development of evidence-based policies and guidelines for clinical, public health and other practitioners.
