Im EO, et al. - From two larger Internet survey studies, researchers analyzed data of 164 midlife women (62 women diagnosed with type 2 diabetes and 102 women without diabetes) from four major racial/ethnic groups in the United States in order to ascertain the associations between type 2 diabetes mellitus and sleep-related symptoms among these women. The mean total number of sleep-related symptoms and their mean total severity score were significantly higher in those with type 2 diabetes than those without diabetes. Among postmenopausal women and Asian women, total numbers and total severity scores significantly differed between those with type 2 diabetes and those without diabetes. Findings from this secondary analysis thereby support that type 2 diabetes is significantly correlated with sleep-related symptoms of midlife women from four major racial/ethnic groups in the United States.
