The Impact of Diabetes Mellitus Duration and Complications on Health-Related Quality of Life Among Type 2 Diabetic Patients in Khamis Mushit City, Saudi Arabia.

BACKGROUND AND

objectivesDiabetes mellitus is one of the most significant public health problems in Saudi Arabia. Therefore, this study aims to investigate the impact of disease duration and disease complications on health-related quality of life among type 2 diabetic patients. MATERIALS AND

methodsA cross-sectional study was conducted on 380 adult diabetic type 2 patients at a tertiary hospital in the city of Khamis Mushit in Saudi Arabia. The participants were asked to complete a pre-validated health status questionnaire (SF-36) consisting of 36 questions measuring eight domains of health, with each domain providing a score from 0 to 100. Demographic and clinical variables were collected using a diabetes type 2 specification form designed to be used in conjunction with the health status questionnaire. The clinical data included variables such as duration of diabetes, co-morbidities, and treatment modality. Statistical analysis was conducted using SPSS version 22 (IBM Corp., Armonk, NY, USA), with differences tested using various statistical tests. Spearman correlation was done between the score and continuous variables, such as age and BMI. A p-value less than 0.05 was considered statistically significant.

resultsMost of the participants (40%) were recently diagnosed with diabetes mellitus (less than one year ago) and 29.5% of the participants were diagnosed with diabetes mellitus within one to five years. The percentage of those with complications was 39.2%, which was mainly diabetic foot (43.4%) followed by nephropathy (29.5%). 46.8% of the participants were admitted due to conditions related to diabetes mellitus. Dietary modifications were prescribed in 38.4% of the participants, 19.5% used non-insulin medications only, 22.6% were on insulin, and 19.5% were using oral medications and insulin. The relationship between diabetes mellitus complications and quality of life domains revealed no significant difference in most of the domains except physical function and general health, which were lower with complicated diabetes melitus. Similarly, the relation between diabetes mellitus duration and quality of life domains was also not significant in all domains except physical function, which was low with a duration of more than 10 years.

conclusionsUnderstandably, the complications associated with diabetes melitus resulted in low quality of life - in terms of physical function and general health - due to the organ-dysfunction associated with poor glycaemic control. Similarly, disease duration greater than 10 years resulted in impaired physical functioning.
