Abstract

INTRODUCTION

Mid-upper arm circumference (MUAC) is widely recognized as an adequate indicator of nutritional status.

OBJECTIVE

To estimate the reference percentiles for MUAC, upper arm muscle area (UAMA), and upper arm fat area (UAFA) in the Argentine child and adolescent population using the LMS method (lambda, mu, sigma).

MATERIALS AND METHODS

The sample was made up of schoolchildren aged 4.0-13.9 years living in Jujuy, Catamarca, Misiones, Buenos Aires, Mendoza, and Chubut. MUAC and tricipital skinfold anthropometric measurements were obtained between 2003 and 2008 as per standardized protocols. UAMA and UAFA were calculated, and percentiles by age and sex were estimated and compared using an analysis of variance.

RESULTS

A total of 22 736 schoolchildren (11 397 boys and 11 339 girls) were included. The 50th percentile was higher for the MUAC and UAFA among girls and for the UAMA among boys. The MUAC curves showed sharper increases as of 7 years old in all percentiles among both boys and girls. A similar pattern was observed for the UAMA, with higher values among boys. Lastly, the UAFA showed a constant increase among girls and a stabilization among boys as of 11 years old. Differences for age were observed.

CONCLUSIONS

The tabulated and plotted percentiles and the MUAC, UAMA, and UAFA may be used as local references for epidemiological and anthropological studies.

摘要

引言

上臂中部周长（MUAC）被广泛认为是营养状况的一个适当指标。

目的

使用LMS方法（λ、μ、σ）估计阿根廷儿童和青少年人群中MUAC、上臂肌肉面积（UAMA）和上臂脂肪面积（UAFA）的参考百分位数。

材料与方法

样本由居住在胡胡伊省、卡塔马卡省、米西奥内斯省、布宜诺斯艾利斯省、门多萨省和丘布特省的4.0至13.9岁学童组成。2003年至2008年期间，按照标准化方案获取了MUAC和三头肌皮褶厚度的人体测量数据。计算了UAMA和UAFA，并通过方差分析估计和比较了按年龄和性别的百分位数。

结果

共纳入22736名学童（11397名男孩和11339名女孩）。女孩的MUAC和UAFA以及男孩的UAMA的第50百分位数更高。MUAC曲线在男孩和女孩的所有百分位数中从7岁起显示出更急剧的增加。UAMA也观察到类似模式，男孩的值更高。最后，UAFA在女孩中持续增加，在男孩中从11岁起趋于稳定。观察到年龄差异。
