摘要:
探讨北京市海淀区6~15岁儿童青少年足底压力与体成分的关系,为儿童少年足底压力诊断及健康管理提供依据.方法 采用随机抽样方法选取北京市海淀区北京大学附属小学和上地实验学校6~15岁健康儿童少年l000人,按实际年龄组分为10组,每组100人,其中男女各50人,进行体成分和足底压力测试.采用Pearson相关分析得出各年龄组男女少儿足底压力与体成分的相关系数.结果 男生足底所有区域峰值压强与体重、相对去脂体重呈负相关,与相对体脂肪、BMI呈正相关(P值均<0.05).男生相对峰值压力、相对接触面积在部分区域与体重、相对去脂体重和BMI呈负相关,与相对体脂肪呈正相关(P值均<0.05),在其他一些区域则相反.女生所有区域峰值压强与体重、相对体脂肪、BMI呈正相关,与相对去脂体重呈负相关(P值均<0.05).女生相对峰值压力在部分区域与体重、相对体脂肪、BMI呈负相关,与相对去脂体重呈正相关(P值均<0.05).女生相对接触面积在部分区域与体重、相对去脂体重呈负相关,与相对体脂肪、BMI呈正相关(P值均<0.05),在其他一些区域则相反.结论 健康少儿足底压力各指标的变化与体成分各指标的变化有关,且不同性别影响有差异.

Abstract:
Objective The aim of this study was to investigate the correlation between the indices of body pressure and body composition among children aged 6-15 years,as well as to understand the impact of body composition on plantar pressure for foot disease prevention in children.Methods Body composition and plantar pressure was measured among healthy children and adolescents aged 6-15 years old random selected from one primary school and one middle school in Haidian District of Beijing.All the 1 000 participants were classified into age-and sex-specific groups,each age group consisted of 50 boys and 50 girls.Relationship between body composition and plantar pressure were analyzed by Pearson correlation analysis.Results Significant negative correlations were found between peak pressure,body weight and relative fat free mass(P<0.05),while positive relation between relative fat mass and BMI was found(P<0.05).Among boys,relative peak force negatively correlated with body weight,relative fat free mass and BMI(P<0.05),and positively correlated with relative fat mass (P<0.05).In girls,peak pressure positively correlated with body weight,relative fat mass and BMI(P<0.05),and negatively correlated with relative fat free mass(P<0.05).Significant negative correlations were found between relative peak force with body mass,relative fat mass and BMI(P<0.05),and positive correlation was found with relative fat free mass(P<0.05).In some other areas showed opposite correlations.Conclusion Foot pressure among healthy children and adolescent relates with body composition,with significant sex difference.
