Short leg length (LL) and childhood obesity have been independently associated with a higher risk for adult disease. However, the contribution of relative LL to overweight and obesity in children remains an under-researched area.
To utilize data from a large cross-sectional anthropometric survey to assess the association of LL to height ratio (LLHR, leg length/height) with measures of overweight and obesity in British children.
Children were analysed from the bottom and top body mass index (BMI) standard deviation score (SDS) quartiles (3825 children, boys=1686) or waist circumference (WC) SDS quartiles (3824 children, boys=1687). The top quartile was defined as the 'high' BMI or WC SDS group and the lower bottom quartile as the 'low' BMI or WC SDS group. Height and LL were expressed as SDSs using current references and LLHR was calculated.
Children in the 'high' groups were taller with longer legs but had a lower LLHR across most ages. The magnitude of the difference was greater for BMI than WC in both genders.
Altered body dimensions appear to be linked to measures of overweight and obesity in children but longitudinal studies are needed to confirm this suggestion.
腿短和儿童期肥胖各自都与成人疾病的较高风险相关。然而，相对腿长对儿童超重和肥胖的影响仍属于研究不足的领域。
利用一项大型横断面人体测量调查的数据，评估英国儿童的腿长与身高比（LLHR，腿长/身高）与超重和肥胖指标之间的关联。
对来自体重指数（BMI）标准差评分（SDS）四分位数底部和顶部（3825名儿童，男孩1686名）或腰围（WC）SDS四分位数（3824名儿童，男孩1687名）的儿童进行分析。四分位数顶部被定义为“高”BMI或WC SDS组，底部四分位数被定义为“低”BMI或WC SDS组。使用当前参考标准将身高和腿长表示为SDS，并计算LLHR。
“高”组儿童在大多数年龄段身高更高、腿更长，但LLHR更低。在两个性别中，BMI组的差异幅度均大于WC组。
身体尺寸的改变似乎与儿童超重和肥胖指标相关，但需要纵向研究来证实这一观点。
