饮食行为可能是肥胖遗传风险的表现,也是日后饮食失调的潜在先兆。然而,儿童期的饮食行为是异质的和短暂的。在这里,我们使用雅芳父母和儿童纵向研究(ALSPAC)的数据,N= 7,825,显示了体重指数(BMI-PGS)和神经性厌食症(AN-PGS)的多基因评分与前十年生活中饮食行为轨迹之间的关联。结果表明,BMI-PGS的标准差(SD)增加与儿童早期和中期暴饮暴食的风险增加30-37%相关。相比之下,BMI-PGS增加一个SD与持续高水平饮食不足的风险降低20%和持续挑食的风险降低15%相关。没有证据表明AN-PGS和饮食行为轨迹之间存在显著关联。我们的研究结果支持了这样一种观点,即儿童饮食行为与BMI相关的常见遗传变异。
Eating behaviors may be expressions of genetic risk for obesity and are potential antecedents of later eating disorders. However, childhood eating behaviors are heterogeneous and transient. Here we show associations between polygenic scores for body mass index (BMI-PGS) and anorexia nervosa (AN-PGS) with eating behavior trajectories during the first ten years of life using data from the Avon Longitudinal Study of Parents and Children (ALSPAC), N=7,825. Results indicated that one standard deviation (SD) increase in the BMI-PGS was associated with a 30-37% increased risk for early- and mid-childhood overeating. In contrast, one SD increase in BMI-PGS was associated with a 20% decrease in risk of persistent high levels of undereating and a 15% decrease in risk of persistent fussy eating. There was no evidence for a significant association between AN-PGS and eating behavior trajectories. Our results support the notion that child eating behavior share common genetic variants associated with BMI.
