OBJECTIVE: This study aimed to determine the health-related quality of life among patients with type II diabetes mellitus (T2DM) using insulin therapy.
METHODS: Cross-sectional observational study design was used to collect data from Malaysian patients with T2DM. Subjective and objective assessments were made either by using several questionnaires or each patient's specific medication profile registered to care sites. Study participants were recruited from both public hospitals and community health clinics located in Kuala Lumpur, Malaysia.
RESULTS: A total of 430 patients with T2DM were recruited in this study with a response rate of 94.7%. The oral antidiabetic medication (OAM) group consisted of 63.0% of the study population and the rest (37.0%) were Insulin users. The body mass index and glycosylated hemoglobin patterns were significantly different between groups (P < 0.011 and P < 0.001). Insulin users showed high percentages of healthy body mass index index (44.7%) compared with OAM users (35.8%) and controlled glycemic index (glycosylated hemoglobin ≤7.5%) was significantly (P = 0.001) better among the insulin-user group compared with the OAM group. The Euro Quality of Life-5 dimension domain analysis indicated significant differences with domains of usual work (P < 0.047), pain and discomfort (P < 0.041), and anxiety and depression (P < 0.001) among insulin users versus OAM users. We also observed a significant difference between the groups regarding diet, monitoring, and disease-specific knowledge. The mean (SD) adherence score showed that insulin users were significantly (P < 0.001) more adherent (6.09 [2.98]) than OAM were nonadherent (4.19 [4.68]).
CONCLUSIONS: This study suggests the valuable effect of insulin therapy among patients with T2DM compared with OAMs on health-related quality of life, medication adherence, and health state. Insulin users reported they had better diabetes-related knowledge and treatment adherence characteristics than noninsulin users.
METHODS: A cross-sectional observational study was conducted to assess the effect of health-related and psychosocial correlates on HRQOL of IDDM patients in Penang, Malaysia. The participants were recruited from five governmental diabetic clinics. Patients with insulin use only, IDDM diagnosed at least 1 year earlier, were identified from clinical registers. The sample was then age stratified for 20-64 years, and severe complications (e.g., end-stage renal failure, hemodialysis, and liver cirrhosis) were excluded; a total of 1003 participants were enrolled in the study. Multivariate regression analysis was used to predict the response.
RESULTS: A total of 853 (100%) participants were enrolled and completed the study. Women exhibited significantly higher/better mental health (p < 0.013) and health perception scores (p < 0.001) despite high prevalence of impaired role (49.2%), social (24.2%), and physical (40.5%) functionings as compared to men. Women with longer diabetes exposure and uncontrolled glycemic levels (HbA1c) have poorer HRQOL. Availability of social support showed no significant association with either HRQOL or diabetes distress levels. Diabetes distress levels remained not associated with social support. Women also showed significantly higher association with health perception (15% versus 13% men, p < 0.001) and mental health (13% versus 11% men, p < 0.001) in diabetes-specific psychosocial factors. Thus, among women alone, diabetes-related specific and psychosocial factors explained 15% and 13% of variations in HRQOL extents, respectively.
CONCLUSION: Women exhibit extensive and significant patterns with health-related factors and diabetes-specific psychosocial factors (self-efficacy, social support, and DLC) to improve HRQOL. Also, women have significantly high reported distress levels and low social functioning compared to men.
