To examine the frequency of night eating (NE) and its relation to binge eating disorder (BED), eating-disorder psychopathology, depression, and metabolic variables in treatment-seeking obese Hispanic men and women.
A consecutive series of 79 obese monolingual Spanish-speaking-only Hispanic patients with BED (N = 40) and without BED (N = 39) were reliably assessed by bilingual research-clinicians using Spanish-language versions of semistructured interviews and measures.
Overall, 38% (N = 30) of the 79 patients reported regular NE (≥4 days/month). NE and BED were significantly associated; 70% (21/30) of NE versus 18% (9/49) of non-NE had BED. Patients with NE reported greater frequency of binge-eating and higher levels of eating-disorder psychopathology and depression than non-NE patients; group differences in eating disorder psychopathology and depression levels persisted after controlling for BED status. The NE and non-NE groups did not differ significantly in BMI or metabolic variables.
In obese treatment-seeking Hispanic patients, NE and BED were significantly associated and NE was associated with heightened eating-disorder psychopathology and depression even after controlling for BED status.
探讨夜食（NE）的发生频率及其与暴食障碍（BED）、饮食障碍病理、抑郁和代谢变量的关系，研究对象为寻求治疗的肥胖西班牙裔男性和女性。
通过双语研究临床医生使用西班牙语版本的半结构化访谈和评估工具，对 79 名患有 BED（N=40）和不患有 BED（N=39）的单一语言西班牙语肥胖西班牙裔患者进行了可靠的评估。
总体而言，79 名患者中有 38%（N=30）报告了经常出现夜食（≥4 天/月）。NE 和 BED 显著相关；70%（21/30）的夜食患者有 BED，而非夜食患者中仅为 18%（9/49）。与非夜食患者相比，夜食患者的暴食行为更为频繁，饮食障碍病理和抑郁程度更高；在控制 BED 状态后，饮食障碍病理和抑郁水平的组间差异仍然存在。NE 组和非夜食组在 BMI 或代谢变量方面没有显著差异。
在寻求治疗的肥胖西班牙裔患者中，NE 和 BED 显著相关，且即使在控制 BED 状态后，NE 仍与更严重的饮食障碍病理和抑郁有关。
