Obesity is one of the greatest public health challenges in the world with childhood prevalence rates between 20-26% and numerous associated health risks. The aim of the current study was to analyze the 11-year follow-up data of the Ulm Birth Cohort Study (UBCS), to identify whether abnormal eating behavior patterns, especially restrained eating, predict body mass index (BMI) at 11 years of age and to explore other factors known to be longitudinally associated with it. Of the original UBCS, n = 422 children (~ 40% of the original sample) and their parents participated in the 11-year follow-up. BMI at age 8 and 11 as well as information on restrained eating, psychological problems, depressive symptoms, lifestyle, and IQ at age 8 were assessed. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to predict children's BMI scores at age 11. PLS-SEM explained 68% of the variance of BMI at age 11, with BMI at age 8 being the most important predictor. Restrained eating, via BMI at age 8 as well as parental BMI, had further weak associations with BMI at age 11; no other predictor was statistically significant. Since established overweight at age 8 already predicts BMI scores at age 11 longitudinally, obesity interventions should be implemented in early childhood.
肥胖是全球最大的公共卫生挑战之一，儿童肥胖患病率在20%-26%之间，且存在众多相关健康风险。本研究的目的是分析乌尔姆出生队列研究（UBCS）的11年随访数据，确定异常饮食行为模式，尤其是节制饮食，是否能预测11岁时的体重指数（BMI），并探索其他已知与之存在纵向关联的因素。在最初的UBCS中，n = 422名儿童（约占原始样本的40%）及其父母参与了11年随访。评估了8岁和11岁时的BMI以及8岁时的节制饮食、心理问题、抑郁症状、生活方式和智商信息。采用偏最小二乘结构方程模型（PLS-SEM）预测儿童11岁时的BMI分数。PLS-SEM解释了11岁时BMI方差的68%，其中8岁时的BMI是最重要的预测因素。节制饮食通过8岁时的BMI以及父母的BMI与11岁时的BMI存在进一步的微弱关联；没有其他预测因素具有统计学意义。由于8岁时已确定的超重可纵向预测11岁时的BMI分数，肥胖干预应在幼儿期实施。
