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.
适应速度较慢与更大的能量摄入和体重有关。本研究旨在评估在 66 名 8-12 岁的瘦儿童中，适应速度较慢是否与 12 个月内 zBMI 的变化呈前瞻性相关，以及适应速度是否是一个稳定的行为表型。结果表明，控制儿童性别、年龄、初始 zBMI、饮食意识和少数族裔地位后，适应速度较慢预测 zBMI 变化更大。此外，适应速度在观察的一年中是稳定的。这些数据表明，适应速度较慢可能是体重增加和肥胖发展的危险因素。需要进一步的研究来了解这种影响的机制，并评估适应表型是否与其他行为表型（如食物强化）相互作用，从而影响 zBMI 的增加。
