To investigate associations between eating behavior constructs (social eating, perceived competence, habit automaticity, self-determined motivation) and diet quality among young adults.
Cross-sectional analysis.
Young adults (n = 1,005; mean age, 21.7 ± 2.0 years; 85% female) enrolled in the Advice, Ideas, and Motivation for My Eating (Aim4Me) study.
Four eating behavior measures collected via online surveys: Social Eating Scale, Perceived Competence in Healthy Eating Scale, Self-Report Behavioral Automaticity Index, and Regulation of Eating Behaviors scales. Diet quality was assessed using the Australian Recommended Food Score (ARFS) and percentage energy from energy-dense, nutrient-poor (EDNP) foods.
Multivariate linear regression investigating associations between eating behavior measures (independent variables) and ARFS and EDNP foods (dependent variables), adjusting for sociodemographic and lifestyle confounders.
Greater perceived competence in healthy eating and behavioral automaticity for consuming healthy foods, limiting EDNP food intake, and higher intrinsic motivation, integrated regulation, and identified regulation of eating behaviors were associated with higher ARFS and lower percentage energy EDNP foods (P < 0.001). Greater self-reported social influence on eating behaviors was associated with higher ARFS (P = 0.01). Higher amotivation was associated with greater % energy from EDNP foods (P < 0.001).
Perceived competence, habit automaticity, and self-determined motivation are determinants of diet quality in young adults. These findings support the development of interventions that promote healthy eating habits by focusing on eating behavior constructs and evaluating their use in improving diet quality.
调查年轻成年人的饮食行为结构（社交饮食、感知能力、习惯自动性、自我决定动机）与饮食质量之间的关联。
横断面分析。
参加 Advice、Idea 和 Motivation for My Eating（Aim4Me）研究的年轻成年人（n=1005；平均年龄 21.7±2.0 岁，85%为女性）。
通过在线调查收集的四项饮食行为措施：社交饮食量表、健康饮食感知能力量表、自我报告行为自动性指数和饮食行为调节量表。饮食质量使用澳大利亚推荐食品评分（ARFS）和能量密集、营养贫乏（EDNP）食品的能量百分比进行评估。
多元线性回归分析饮食行为措施（自变量）与 ARFS 和 EDNP 食品（因变量）之间的关联，调整社会人口统计学和生活方式混杂因素。
健康饮食感知能力和食用健康食品的习惯自动性更高、限制 EDNP 食品摄入量、内在动机、综合调节和认同调节更高，与 ARFS 更高、EDNP 食品能量百分比更低相关（P<0.001）。自我报告的饮食行为受到更大的社交影响与 ARFS 更高相关（P=0.01）。更高的无动机与 EDNP 食品的能量百分比更高相关（P<0.001）。
感知能力、习惯自动性和自我决定动机是年轻成年人饮食质量的决定因素。这些发现支持通过关注饮食行为结构并评估其在改善饮食质量方面的应用来开发促进健康饮食习惯的干预措施。
