Use of Complementary and Alternative Medicine and Its Relationship with Health-Related Quality of Life (HRQOL) in Patients with Type 2 Diabetes Mellitus

The present study investigated the use of complementary and alternative medicine (CAM) and its relationship with health-related quality of life (HRQOL) in patients with type 2 diabetes mellitus. A total of 421 patients with type 2 diabetes mellitus who completely met the inclusion criteria, aged 67.3 ± 12.8 years, among 622 outpatients were recruited in this cross-sectional study. We examined the use of CAM, such as supplements, Kampo, acupuncture, and yoga. HRQOL was assessed by EuroQOL. A total of 161 patients (38.2%) with type 2 diabetes mellitus used some type of CAM. The use of supplements and/or health foods was the highest among CAM users (112 subjects, 26.6%). HRQOL was significantly lower in patients who used some CAM (0.829 ± 0.221) than in those without any CAM use (0.881 ± 0.189), even after adjustments for confounding factors [F(1, 414) = 2.530, p = 0.014]. Proper information on CAM is needed for patients with type 2 diabetes mellitus.
