摘要

目的：尽管新出现的证据表明，剥夺和不可预测性这两个独特的早期逆境维度可能与饮食有关，但这种联系尚未在关键的发育时期通过对饮食质量和饮食行为的有力测量进行检验。这项研究的目的是研究早期剥夺和不可预测性的经历可能对青春期以后的饮食产生的独特影响。方法：这项纵向研究的参与者是337名儿童（51%为女性），最初招募的年龄在3至6岁之间。剥夺和不可预测性分别在学龄前通过观察和主要照顾者自我报告进行测量。通过24小时自动自我管理的24小时饮食评估工具（ASA24）和三因素饮食问卷R-18 (TFEQ-R18)，在三个时间点测量青少年的饮食情况，评估饮食质量，评估饮食行为。本研究利用结构方程模型来检验剥夺、不可预测性和饮食质量（模型1）之间以及剥夺、不可预测性和饮食行为（模型2）之间的纵向关联，同时控制性别、社会经济地位和母亲教育（两个模型）。结果：早期被剥夺的经历与青春期高热量摄入和情绪化进食有着独特的联系。另外，早期不可预测性的经历与青春期低热量摄入有独特的联系。结论：早期剥夺和不可预测性的经历成为整个青春期热量摄入和情绪性饮食（仅剥夺）的重要预测因素。这些结果对通过确定早期可修改的目标来减少青少年不健康饮食的干预和预防工作具有潜在的意义。

Examining Longitudinal Associations Between Early Environmental Deprivation and Unpredictability and Dietary Quality and Eating Behaviors a Decade Later

Purpose

Although emerging evidence suggests that deprivation and unpredictability, two unique dimensions of early adversity, may be associated with eating, this association has not been examined across key developmental periods with robust measurement of dietary quality and eating behaviors. This study aims to examine the unique effect that experience of early deprivation and unpredictability may have on later eating across adolescence.

Methods

Participants in this longitudinal study were 337 children (51% female) initially recruited between ages 3 and 6. Deprivation and unpredictability were measured upon study entry during preschool by observation and primary caregiver self-report, respectively. Eating across adolescence was measured at three time points by 24-hour dietary recalls via the Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA24), assessing for dietary quality, and the Three-Factor Eating Questionnaire R-18 (TFEQ-R18), assessing for eating behaviors. This study utilized structural equation modeling to examine longitudinal associations between deprivation, unpredictability, and dietary quality (Model #1) and between deprivation, unpredictability, and eating behaviors (Model #2), while controlling for sex, socioeconomic status, and maternal education (both models).

Results

Greater experience of early deprivation was uniquely associated with higher caloric intake and greater emotional eating across adolescence. Alternatively, greater experience of early unpredictability was uniquely associated with lower caloric intake across adolescence.

Conclusion

Experience of early deprivation and unpredictability emerged as significant predictors of caloric intake and emotional eating (deprivation only) across adolescence. These results have potential implications for interventions and prevention efforts aimed at reducing less healthful eating across adolescence by identifying early modifiable targets.

期刊介绍： Appetite is an international research journal specializing in cultural, social, psychological, sensory and physiological influences on the selection and intake of foods and drinks. It covers normal and disordered eating and drinking and welcomes studies of both human and non-human animal behaviour toward food. Appetite publishes research reports, reviews and commentaries. Thematic special issues appear regularly. From time to time the journal carries abstracts from professional meetings. Submissions to Appetite are expected to be based primarily on observations directly related to the selection and intake of foods and drinks; papers that are primarily focused on topics such as nutrition or obesity will not be considered unless they specifically make a novel scientific contribution to the understanding of appetite in line with the journal's aims and scope.
