缓慢的习惯化速率与更大的能量摄入和体重有横截面关系。本研究旨在评估在66名8-12岁的瘦儿童中，缓慢的习惯化速率是否与12个月期间的zBMI变化具有前瞻性相关性，以及习惯化速率是否是稳定的行为表型。结果表明，较慢的习惯化速度预测更大的zBMI变化，控制儿童性别，年龄，初始zBMI，饮食意识和少数民族地位。此外，在观察的一年中，习惯化率保持稳定。这些数据表明，缓慢的习惯化速度可能是体重增加和肥胖发展的风险因素。未来的研究需要了解这种效应的机制，并评估习惯化表型是否与其他行为表型（如食物强化）相互作用，以影响zBMI的增加。(C)2011爱思唯尔有限公司保留所有权利。
Slow rates of habituation are cross-sectionally related to greater energy intake and body weight. The present study is designed to assess whether slow rates of habituation are prospectively related to zBMI change over a 12 month period in 66 lean 8-12 year-old children, and whether the rate of habituation is a stable behavioral phenotype. Results showed that slower rates of habituation predicted greater zBMI change, controlling for child sex, age, initial zBMI, dietary awareness and minority status. In addition, the rate of habituation was stable over the year of observation. These data suggest that slow rates of habituation may be a risk factor for weight gain and the development of obesity. Future research is needed to understand the mechanism for this effect, and assess whether the habituation phenotype interacts with other behavioral phenotypes, such as food reinforcement, to influence increases in zBMI.
