Illness perception, medication adherence and glycemic control among primary health-care patients with type 2 diabetes mellitus at Port Said City, Egypt.

Aims: Despite the availability of a wide selection of antidiabetic treatments, many patients with type 2 diabetes mellitus (T2DM) still do not have controlled glucose levels. This study aimed to assess illness perception, medication adherence, and glycemic control among primary care attendees with T2DM.
Methods: A cross-sectional study was conducted between July 2019 and November 2020. A random sample of 265 Egyptian T2DM patients were enrolled from primary health-care settings in Port Said, Egypt. Data on socio-demographic characteristics, lifestyle habits, and diabetic medical history were collected using a semi-structured questionnaire. The Brief Illness Perception Questionnaire (B-IPQ) was used to assess diabetes perception, whereas the 8-item Morisky Medication Adherence Scale (MMAS-8) was used to investigate medication adherence.
Results: There was a significant difference in B-IPQ scores between different groups of the patients in terms of diabetic medications, complications, and glycemic control (p < 0.05). There was a significant difference in MMAS-8 score found between different groups of the patients in terms of disease duration, family history of T2DM, and glycemic control (p < 0.05). Further, there was a significant difference in HbA1c score found between different groups of patients in terms of disease duration, medications, complications, and family history of T2DM (p < 0.05). Higher BMI, a positive family history of T2DM, patients who take insulin, high illness perception, and poor medication adherence were the factors associated with higher HbA1c level.
Conclusion: Higher HbA1c levels were linked to a higher BMI, a positive family history of T2DM, insulin users, high illness perception, and poor medication adherence. © The Japan Diabetes Society 2022.
