To examine the link between disturbed sleep and depression scores in Mexican Americans and non-Hispanic Whites.
Data were analyzed for 566 participants (45% Mexican Americans) who were part of a rural healthcare study, Project FRONTIER. Mean age was 55.5 years for Mexican Americans (70% female) and 65.6 years for non-Hispanic Whites (69% female). Self-reported sleep disturbance was entered as the predictor, GDS-30 total and factor scores as the outcome variables, and age, sex, education, BMI, and medical diagnoses (hyperlipidemia, diabetes mellitus, and hypertension) entered as covariates.
Mexican Americans reported higher rates of sleep disturbances (25%) than non-Hispanic whites (17%). Sleep disturbances were significantly associated with GDS-30 total scores and the factors Dysphoria and Cognitive Impairment in both Mexican Americans and non-Hispanic whites.
In this study, Mexican Americans reported higher rates of sleep disturbances than non-Hispanic whites. Disturbed sleep was positively associated with depression and the factor scores for Dysphoria and Cognitive Impairment in both groups. Given the paucity of research on sleep disorders in Mexican Americans, identifying what sleep disorders are present and the impact treating these sleep disorders have on depression warrant further investigation.
探讨墨西哥裔美国人和非西班牙裔白人间睡眠障碍与抑郁评分的关系。
对参与农村医疗保健研究项目 FRONTIER 的 566 名参与者（45%为墨西哥裔美国人）的数据进行了分析。墨西哥裔美国人的平均年龄为 55.5 岁（70%为女性），非西班牙裔白人为 65.6 岁（69%为女性）。将自我报告的睡眠障碍作为预测因子，将 GDS-30 总分和因子得分作为因变量，年龄、性别、教育程度、BMI 和医学诊断（高脂血症、糖尿病和高血压）作为协变量。
墨西哥裔美国人的睡眠障碍发生率（25%）高于非西班牙裔白人（17%）。睡眠障碍与 GDS-30 总分以及两组中的抑郁和认知障碍因子显著相关。
在这项研究中，墨西哥裔美国人的睡眠障碍发生率高于非西班牙裔白人。在两组中，睡眠障碍与抑郁以及抑郁和认知障碍因子得分呈正相关。鉴于墨西哥裔美国人睡眠障碍研究的匮乏，确定存在哪些睡眠障碍以及治疗这些睡眠障碍对抑郁的影响值得进一步研究。
