645-P: Experiences of Managing Comorbid Obstructive Sleep Apnea and Type 2 Diabetes among Veterans

Abstract

Obstructive sleep apnea (OSA) is highly prevalent in patients with type 2 diabetes (T2DM), more so in veterans compared to non-veterans. Positive airway pressure (PAP) is the recommended first-line treatment for OSA. However, adherence to both PAP and to diabetes management regimens can be challenging to older adults. This study describes older veterans’ experiences managing comorbid OSA and T2DM, and the types of support they receive from family and friends. Methods: We conducted a postal survey of 900 randomly selected veterans (aged ≥50 years with medical diagnoses of OSA and T2DM) from one VA healthcare system. Questions included the Diabetes Patient Behavior Checklist and perceived benefits of and assistance with PAP use. Results: Of the 145 respondents (97% men, 51% White, 21% Black, mean age 72 years), 43% received help for diabetes from family or a friend, including preparing healthy food (91%), providing encouragement for diabetes self-care (89%), and eating at the same time (89%). Almost two thirds of the respondents were current PAP users. Among the respondents, 27% received help using PAP from a household member, including putting on the mask (68%), filling the water reservoir (59%), and cleaning the device (59%). Current PAP users had significantly lower levels of hemoglobin A1c than nonusers (6.7 ± 1.1 vs. 7.3± 1.6 %, respectively, p=0.008). Current PAP users also reported significantly higher perceived benefits of PAP use on improving sleep quality, sleep apnea, diabetes, and general health than nonusers. Married or non-White respondents thought it would be more helpful for a family member or friend to receive education on treatment of both OSA and T2DM. Conclusion: Future studies should investigate feasible strategies for addressing adherence to PAP use as part of diabetes self-management to improve glycemic control and overall health outcomes among patients with T2DM and comorbid OSA. Family support and social/demographic factors should be considered. Disclosure Y.Song: None. S.E.Choi: None. A.Papazyan: None. P.M.Macey: None. C.Alessi: None. C.H.Fung: None. J.Martin: None.
