Picky eating (PE) is common across the lifespan and related to psychosocial impairment and limited dietary variety. However, research about PE in non-Western countries is limited. Because eating behaviors may differ by culture, operationalizing PE in non-Western countries (e.g., China) is needed. The present study aimed to replicate two previous studies identifying PE profiles in Western countries by using latent profile analysis (LPA) to classify and characterize adults reporting picky eating in a Chinese sample.
A sample of 1,068 Chinese young adults completed a battery of questionnaires including the adult eating behavior questionnaire (AEBQ). LPA was utilized to identify eating profiles. The three-step approach was used to examine predictors of latent memberships and profile differences on various self-reported measures.
The best fit was a four-profile solution, with two picky eating profiles emerging: picky eating and severe picky eating. Compared to those in the other two profiles, participants in the picky eating profile (19.4%) and severe picky eating profile (3.3%) had significantly higher scores on self-reported eating disorder symptoms and psychological distress, and lower scores on self-reported food-related life satisfaction. Relative to the picky eating profile, participants in the severe picky eating profile reported significantly greater self-reported eating disorder symptoms, psychological distress, and food-related dissatisfaction.
Characterizing PE profiles is an important step toward understanding eating behaviors among Chinese young adults. Identifying various eating profiles has implications for future research related to PE, including the development of diagnostic tools and interventions to address PE in a Chinese context.
挑食(PE)在整个生命周期中都很常见,与心理社会障碍和饮食种类有限有关。然而,非西方国家的相关研究有限。由于饮食行为可能因文化而异,因此需要在非西方国家(例如中国)对 PE 进行操作化。本研究旨在通过使用潜在剖面分析(LPA)对报告在中国样本中存在挑食行为的成年人进行分类和特征描述,复制之前在西方国家确定 PE 特征的两项研究。
1068 名中国年轻成年人完成了一系列问卷,包括成人饮食行为问卷(AEBQ)。使用潜在剖面分析(LPA)来确定饮食特征。采用三步法来检验潜在成员身份和各种自我报告指标上的特征差异的预测因子。
最佳拟合是四特征解,出现了两种挑食特征:挑食和严重挑食。与其他两种特征相比,挑食特征(19.4%)和严重挑食特征(3.3%)的参与者在自我报告的饮食障碍症状和心理困扰方面的得分明显更高,而在自我报告的与食物相关的生活满意度方面的得分则较低。与挑食特征相比,严重挑食特征的参与者报告的自我报告的饮食障碍症状、心理困扰和与食物相关的不满程度明显更高。
对 PE 特征进行描述是理解中国年轻成年人饮食行为的重要一步。确定各种饮食特征对 PE 的未来研究具有启示意义,包括在中国背景下开发诊断工具和干预措施以解决 PE 的问题。
