Background: The population of elderly persons with diabetes mellitus is increasing worldwide. However, there is scarcity of data on this subgroup of diabetic subjects in our locale. Objective: To study the clinical and biochemical characteristics of elderly diabetic subjects who developed DM at the age of 65 years and above. Subjects and Methods: Hospital records of all persons with type 2 DM seen at a Diabetes Clinic in Benin City, Nigeria who were diagnosed at the age of 65 years and above were retrieved for the study. Data on patient's age, sex, duration of diabetes mellitus, body mass index, waist circumference, blood pressure, fasting plasma glucose, glycosylated hemoglobin A1c (HbA1c), and fasting lipid profile were extracted. Medical records of clinic patients with DM who were diagnosed before the age of 65 years served as controls. Results: Sixty-three patients who developed DM at the age of 65 years and above were included as study subjects while 398 who developed DM before the age of 65 years served as controls. The study subjects consisted of 33 (52.4%) females and 30 (47.6%) males. The mean ± SEM age of study subjects was 73.40 ± 0.72 years (min-max, 66-92 years). Thirty-three (52.4%) of the study subjects had concurrent DM and hypertension. Hypertension and generalized obesity were found in 30 (47.6%) and 8 (12.7%) subjects, respectively. Abdominal obesity was found in 28 (44.4%) of female and in 12 (19%) of male study subjects. The mean body mass index (BMI) was significantly larger in the controls than in the study subjects (28.76 ± 0.45 vs. 26.64 ± 0.72; P = 0.016). The mean systolic and diastolic blood pressures and lipid profile were comparable in study subjects and the controls. Conclusion: Hypertension and dyslipidemia were more common in our elderly study subjects but generalized obesity was less common.
