Abstract : Type 2 diabetes mellitus (T2DM) is a noncommunicable illness that develops due to insulin resistance and persistent hyperglycemia. People older than 65 years have a higher chance for getting diabetes. We aimed to measure the quality of life (QoL) among the elderly type 2 diabetic population in Makkah region. A cross-sectional study was done in older adults in Makkah. We included all participants older than 65 years who were diagnosed with T2DM. World Health Organization Quality of Life Brief Version (WHOQOL-BREF) scale was used to measure the QoL among patients with diabetes. Data were analyzed using SPSS statistical program version 25. A total of 399 participants were included. Most participants were between 65 and 70 (65.7%) and 71–75 (23.3%) years. Two hundred and twenty-two (55.6) of them were male. The mean WHOQOL-BREF scale score was 14.83 ± 2.79, and a significant negative correlation was found between WHOQOL-BREF scale scores and participants’ age (r = −0.16, p-value = 0.001) and positive correlation with participants’ educational level (r = 0.275, p-value ≤ 0.001). The overall QoL was high among elderly patients with diabetes. Educational level and age were also correlated with a higher QoL. We should concentrate on increasing the level of education among elderly patients with diabetes to increase their QoL.
