Lastly, the results showed that people living with Type 2 diabetes experience more sleep dysfunction (mean = 28.62, SD = 5.32) than Type 1 diabetes patients (mean = 25.64, SD = 5.92, t = 4.974, p < 0.05) and patients receiving insulin injection management (mean = 27.61, SD = 5.68) more sleep dysfunction than those on oral drugs (mean = 27.61, SD = 5.98, t = 2.919, p < 0.05). The gene discussed is INS; the disease is type 2 diabetes mellitus.
