Background: The present study was designed to evaluate hypertension and dyslipidemia in prediabetic subjects with a family history of type 2 diabetes (first-degree relatives), and they were compared with the normal glucose-tolerance subjects. Materials and Methods: Three thousand and eighty-six (788 men and 2298 women) subjects were selected from a consecutive sample of patients with Impaired Glucose Tolerance (IGT), Impaired Fasting Glucose (IFG), and Combined (IFG and IGT), and their first-degree relatives formed the control group. Potential risk factors for diabetes including age, gender, body size, HbA1c, cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, blood pressure (BP), urine microalbumin, and family and personal medical history were assessed. Results: The studied participants included 300 IGT patients (9.7%), 625 IFG patients (44.9%), 411 combined patients (13.3%), and 1750 (56.7%) normal subjects. Aging led to increase in hypertension. Increase in body mass index (BMI) led to an increase in the prevalence of hypertension significantly in all groups. The mean triglyceride in the normal group was different in comparison with that of the IGT (P < 0.05) and combined (P < 0.001) groups. Differences in total cholesterol were observed in the normal group when compared with the IGT (P < 0.05) and combined (P < 0.001) groups, and of the combined group in comparison with the IGT (P < 0.05) group. The difference in LDL level was related to the combined group in comparison with IGT, marginally (P < 0.1), and normal in comparison with the combined group (P < 0.05). Conclusion: Prevalence of hypertension was not significantly different between the groups, however, in prediabetic patients it was higher than in the normal group, and prevalence of dyslipidemia in prediabetic subjects was significantly higher than in the normal group.
