Fatigue, Pain, Sleep Difficulties, and Depressive Symptoms in Mexican Americans and Chinese Americans with Type 2 Diabetes.

Fatigue, pain, sleep difficulties, and depressive symptoms are common in people with type 2 diabetes (T2DM). However, most studies of diabetes symptoms are not conducted with Mexican- or Chinese Americans. We aim to compare the symptoms between the two ethnic groups and examine the predictors of fatigue. This is a secondary analysis of two datasets (72 Mexican Americans and 134 Chinese Americans with T2DM). The Theory of Unpleasant Symptoms guided variable selection. We used χ2 tests to compare symptoms (measured by the Illness Perception Questionnaire-Revised and CES-D) between the two ethnic groups, and logistic regression to predict fatigue. Compared to Chinese Americans, Mexican Americans reported more fatigue, sleep difficulties, and pain. Depressive symptoms (OR = 6.13, p < 0.001) and medium acculturation (OR = 2.45, p = 0.017) significantly predicted fatigue. The two ethnic groups demonstrated differences in symptoms. Fatigue and related symptoms should be further evaluated in Mexican- and Chinese Americans with T2DM.
