Abstract

Background: Disordered eating behaviors and body dissatisfaction are highly prevalent among adolescents and linked to negative health outcomes. While Hispanic adolescents appear to be at high risk of disordered eating and body dissatisfaction, validated tools for assessment of these health concerns among this population are lacking.

Methods: This study used Confirmatory Factor Analysis to establish factorial validity for the Kids Eating Disorder Survey (KEDS) among a community sample of Hispanic adolescents. Internal consistency was measured by the Kuder-Richardson Formula 20 (KR-20).

Results: Participants (N = 690) were Hispanic (100%) and female (53%), with a mean age of 12 years. After testing the psychometric properties of KEDS and implementing modifications, the resulting two-factor KEDS model (M-KEDS) showed acceptable fit (TLI = 0.98, CFI = 0.99, RMSEA = 0.06) for the Weight Dissatisfaction (renamed to Negative Weight Attitudes) and Purging/Restriction (renamed to Extreme Weight Control Behaviors) sub-scales and good internal consistency (KR-20 = 0.77).

Conclusion: M-KEDS is a factorial valid instrument for assessing Extreme Weight Control Behaviors and Negative Weight Attitudes among Hispanic adolescents. Hispanics are among the fastest-growing racial/ethnic groups in the United States, warranting further research on negative weight attitudes and extreme weight control behaviors in this population.

双因素修改后儿童饮食失调调查（M-KEDS）的开发：对西班牙裔青少年的验证研究。

背景：饮食失调行为和对身体的不满意在青少年中非常普遍，并与不良的健康后果有关。虽然拉美裔青少年似乎是饮食失调和身体不满意的高危人群，但在这一人群中却缺乏评估这些健康问题的有效工具：本研究采用确认性因子分析法，在西语裔青少年社区样本中建立了儿童饮食失调调查（KEDS）的因子效度。内部一致性采用 Kuder-Richardson 公式 20 (KR-20) 进行测量：参与者（N = 690）为西班牙裔（100%）和女性（53%），平均年龄为 12 岁。在对 KEDS 的心理计量特性进行测试并进行修改后，得出的双因素 KEDS 模型（M-KEDS）显示，体重不满意（更名为负重态度）和催促/限制（更名为极端体重控制行为）子量表的拟合度（TLI = 0.98、CFI = 0.99、RMSEA = 0.06）可以接受，内部一致性（KR-20 = 0.77）良好：结论：M-KEDS 是一种对西班牙裔青少年的极端体重控制行为和消极体重态度进行评估的有效工具。西班牙裔是美国增长最快的种族/民族群体之一，因此有必要对这一人群的消极体重态度和极端体重控制行为进行进一步研究。

期刊介绍： Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
