Abstract

Background

Executive control and temperament have been associated with pediatric obesity. However, interactions between these constructs in relation to future weight outcomes have not been investigated.

Objective

This longitudinal study examined early childhood executive control, early temperament (negative affectivity and surgency), and their interactions as predictors of adolescent BMI trajectories.

Methods

At age 5.25, children (N = 229) completed executive control tasks, and parents completed the Child Behavior Questionnaire to assess temperament. BMI was calculated annually between ages 14–17.

Results

Greater early negative affectivity predicted more positive BMI growth. Although early childhood executive control was not associated with BMI growth, greater negative affectivity predicted greater BMI escalation at average and below average executive control abilities.

Conclusions

For children without robust executive control abilities early in development, negative affectivity may be a risk factor for accelerated adolescent BMI growth. Targeted assessment of early risk factors may be useful for childhood obesity prevention efforts.

童年早期的执行控制能调节消极情绪在青少年体重指数增长轨迹中的作用。

背景：执行控制和气质与小儿肥胖有关。然而，这些因素之间的相互作用与未来体重结果的关系尚未得到研究：这项纵向研究考察了儿童早期执行控制、早期气质（消极情绪和暴躁）及其相互作用对青少年 BMI 轨迹的预测作用：5.25岁时，儿童（229人）完成执行控制任务，家长完成儿童行为问卷以评估气质。在14-17岁期间，每年计算一次体重指数：结果：早期负面情绪越多，预示着体重指数的增长越积极。尽管儿童早期的执行控制能力与体重指数的增长无关，但在执行控制能力处于平均水平和低于平均水平的情况下，较强的负情感预示着体重指数会有更大的增长：结论：对于在发育早期没有强大执行控制能力的儿童来说，消极情绪可能是青少年体重指数加速增长的一个风险因素。对早期风险因素进行有针对性的评估可能有助于预防儿童肥胖。

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
