Variation in height among young adults has been linked to the living conditions of different social groups. The aim of this study was to measure variation in the height and knee height of young adults by head of household employment level and family income. The sample comprised 180 individuals (90 girls) aged 16 and 17 years living in the city of Merida, Mexico. Height and knee height were measured by anthropometry, and individuals' family social and economic data collected from their mothers. Variation in these measurements was analysed by three categories of employment and family income terciles. One-way ANOVAs were done by sex to compare mean height and knee height by employment and family income. Coefficients of variation were calculated and a Bartlett test applied. Significant differences in height and knee height were observed only between family income terciles. Both sexes were taller at the highest levels of family income (p<0.05) and men had the highest (p<0.05) knee height. Highest family income individuals exhibited the least variation in height and knee height. Similarity in socioeconomic conditions for families in the lowest family income tercile and with employee heads of household was not associated with lower variation of height and knee height.
年轻人身高的差异与不同社会群体的生活条件有关。本研究旨在通过家庭户主的就业水平和家庭收入来衡量年轻人身高和膝高的差异。该样本包括居住在墨西哥梅里达市的 180 名个体（90 名女孩），年龄在 16 和 17 岁之间。身高和膝高通过人体测量法进行测量，个体的家庭社会和经济数据则从其母亲处收集。通过就业和家庭收入三分位数的三个类别分析这些测量值的差异。通过性别进行单因素方差分析，比较不同就业和家庭收入水平下的平均身高和膝高。计算变异系数并应用巴特利特检验。仅在家庭收入三分位数之间观察到身高和膝高的显著差异。在家庭收入最高的水平下，两性的身高都更高（p<0.05），而男性的膝高最高（p<0.05）。家庭收入最高的个体的身高和膝高变化最小。家庭收入最低三分位数的家庭和有雇员户主的家庭具有相似的社会经济条件，但这与身高和膝高的变化较小无关。
