The purpose of this study was to examine the association between adolescents' body mass index (BMI) z-scores and their subsequent level of schooling, extending previous longitudinal research by using objectively measured weight and height data.
A longitudinal study with 3 study waves (1-year intervals) involving 1248 Dutch adolescents (49% girls; mean age = 13.7 years) at schools providing different educational levels was used to determine adolescents who moved and did not move to a lower educational level in the first year, or in the second year, and to examine whether this movement could be predicted by BMI z-scores (zBMI), after controlling for a large range of potential confounding factors.
A total of 1164 Dutch adolescents continued in the same level of education, whereas 84 adolescents moved to a lower educational level (43 moved in the first and 41 in the second year). A higher zBMI significantly increased the risk of a general transition to a lower educational level, and of a transition in the first year, but not in the second year, after controlling for potential demographic, behavioral, and psychological confounds.
Findings suggest that a higher zBMI during adolescence immediately lowers educational achievement level during general secondary education.
本研究的目的是检验青少年的体重指数（BMI）z分数与其后续教育水平之间的关联，通过使用客观测量的体重和身高数据扩展先前的纵向研究。
一项纵向研究，包含3个研究阶段（间隔1年），涉及1248名荷兰青少年（49%为女孩；平均年龄 = 13.7岁），这些青少年来自提供不同教育水平的学校，用于确定在第一年或第二年转到较低教育水平和未转到较低教育水平的青少年，并在控制一系列潜在混杂因素后，检验这种转变是否可以由BMI z分数（zBMI）预测。
共有1164名荷兰青少年继续处于相同的教育水平，而84名青少年转到了较低的教育水平（43名在第一年，41名在第二年）。在控制潜在的人口统计学、行为学和心理学混杂因素后，较高的zBMI显著增加了总体转到较低教育水平的风险以及第一年转到较低教育水平的风险，但第二年没有增加。
研究结果表明，青少年时期较高的zBMI会立即降低普通中等教育阶段的教育成就水平。
