Short stature may reflect health in early life and be an enduring disability. How birth weight, gender, household, elementary schooling and diet play a role in associations between stature and overall school competence (OSC) have been assessed.
The 2001-2002 Nutrition and Health Survey in Taiwan (NAHSIT) for elementary schoolchildren (n 2274, 52·1 % boys) was linked to birth records. It provided sociodemographic, dietary quality, body compositional and school performance (as Scale for Assessing Emotional Disturbance, SAED; OSC as an SAED subscale) data. Lower birth weight was ≤15th percentile: 2850 g for boys and 2700 g for girls, and stature as z-scores for Taiwanese. Multivariable linear regression was used for relationships between OSC and stature. Trends in OSC by stature and school grade were assessed.
The 2001-2002 NAHSIT for elementary schoolchildren.
Totally, 2274 schoolchildren aged 6-13 years.
Compared to normal height (-2< height for age z-score (HAZ) <2), shorter girls (HAZ ≤ -2) had a lower OSC (8·87 v. 10·5, P < 0·05) and taller girls (HAZ ≥ 2) had a better OSC (12·3 v. 10·5, P < 0·001). Maternal education and household income each contributed more than 5 % of OSC variance. OSC and HAZ among girls were positively associated and emotional disturbance negatively associated. Shortness-associated lower OSC underwent remediation with advancing school grade. Stature and OSC were not evidently related in boys.
Shorter stature can compromise OSC among school girls. The major determinants in shorter girls are less household income and limited parental education.
身材矮小可能反映了早年的健康状况，并且是一种持久的残疾。本研究旨在评估出生体重、性别、家庭、小学教育和饮食在身高与整体学业表现（OSC）之间的关联中所起的作用。
本研究将 2001-2002 年台湾小学生营养与健康调查（NAHSIT）（n=2274，男生占 52.1%）与出生记录相联系。该研究提供了社会人口统计学、饮食质量、身体成分和学业成绩（作为情绪障碍量表，SAED；OSC 作为 SAED 的一个分量表）的数据。较低的出生体重为≤第 15 百分位数：男孩为 2850 克，女孩为 2700 克，身高为台湾人的 z 分数。采用多元线性回归分析 OSC 与身高的关系。评估了 OSC 随身高和学校年级的变化趋势。
2001-2002 年台湾小学生营养与健康调查。
共有 2274 名 6-13 岁的小学生。
与正常身高（-2<身高年龄 z 评分（HAZ）<2）相比，身材矮小的女孩（HAZ ≤-2）的 OSC 较低（8.87 比 10.5，P<0.05），而身材较高的女孩（HAZ≥2）的 OSC 较好（12.3 比 10.5，P<0.001）。母亲的教育和家庭收入对 OSC 方差的贡献均超过 5%。女孩的 OSC 和 HAZ 呈正相关，情绪障碍呈负相关。随着学校年级的升高，与身材矮小相关的较低 OSC 得到了改善。在男孩中，身高和 OSC 之间没有明显的关系。
身材矮小会影响女生的 OSC。身材矮小的主要决定因素是家庭收入较低和父母教育程度有限。
