To measure total body fat content and its regional distribution within the body (head, arms, legs and trunk) in young girls and adolescents in relation to age and body mass index (BMI).
Cross-sectional observational study.
196 healthy Caucasian girls aged 4-16 years living in an urban town in the South Island of New Zealand.
Body weight, height and BMI. Total body fat mass (kg) and the regional distribution of this fat (measured by dual energy X-ray absorptiometry).
All the measured variables, including total and % fat mass were higher in older age groups. Regional distribution of fat differed, with older girls having a higher proportion of their body fat in the trunk and a smaller proportion of their body fat in the heat than younger girls. BMI was positively correlated with % trunk fat (r = 0.700) and negatively correlated with % leg fat (r = -0.465). Girls with higher levels of adiposity (> 75th percentile for BMI) stored more fat in the trunk and correspondingly less in the legs than girls with lower adiposity (< or = 75th percentile for BMI) at five of the six age groups (P < 0.05).
It is concluded that body fat mass increases and shows a more central distribution in young girls as they grow older. Increasing adiposity as determined by BMI is associated with an increase in fat deposition in the trunk and a decrease in the legs.
测量年轻女孩和青少年的全身脂肪含量及其在体内的区域分布（头部、手臂、腿部和躯干），并分析其与年龄和体重指数（BMI）的关系。
横断面观察性研究。
196名健康的白种女孩，年龄在4至16岁之间，居住在新西兰南岛的一个城镇。
体重、身高和BMI。全身脂肪量（kg）及其脂肪的区域分布（通过双能X线吸收法测量）。
所有测量变量，包括总脂肪量和脂肪百分比，在年龄较大的组中更高。脂肪的区域分布有所不同，年龄较大的女孩躯干中脂肪比例较高，而头部中脂肪比例低于年龄较小的女孩。BMI与躯干脂肪百分比呈正相关（r = 0.700），与腿部脂肪百分比呈负相关（r = -0.465）。在六个年龄组中的五个组中，肥胖水平较高（BMI>第75百分位数）的女孩比肥胖水平较低（BMI≤第75百分位数）的女孩在躯干中储存更多脂肪，而在腿部储存的脂肪相应较少（P < 0.05）。
得出的结论是，随着年龄的增长，年轻女孩的体脂肪量增加，且呈现出更向身体中心分布的趋势。由BMI确定的肥胖程度增加与躯干脂肪沉积增加和腿部脂肪沉积减少有关。
