Methods: We matched 96 Cameroonian Controls to 238 (Un) treated HIV-positive patients [HIV] for age. In each participant, aortic PWV (ComplioR), blood pressures (BP), lipid profile and fasting blood glucose (FPG) were measured. Results: Waist circumference was lower in HIV than in Controls (both p g·dl-1), and of diabetes (FPG > 125 mg·dl-1) were higher in HIV than in the Controls (50% vs 27%, and 23% vs 1%, respectively;both p < 0.0001). HDL-C was lower in HIV as compared to the Control (p = 0.02). Fasting triglycerides (TG) and the atherogenic dyslipidemia ratio [log(TG)/HDL-C] were higher in HIV than in the Controls (both p < 0.05). Hypertension prevalence was high but comparable in the two groups (48% vs 44% respectively, p > 0.05). HIV patients exhibited a twice-higher prevalence of MetS (AHA/NHLBI score 33/5) than that of the Controls (41% vs 21%;p 0.01). Similarly, severity of MetS phenotype was higher in HIV as compared to the Controls (2.14% vs 1.59%;p < 0.0001). PWV adjusted for age, mean BP and gender was faster in HIV in comparison to the controls (7.33 m/s vs 6.86 m/s, respectively;p = 0.036). Conclusions: HIV infection is associated with higher prevalence of MetS and its phenotype in Black African patients that may induce increased aortic stiffness.展开更多

The aim of this study was to assess the prevalence and correlates of glucose homeostasis abnormalities (GHA) in the Far-North region of Cameroon, where these variables have not been explored so far. Methods: We included in this population-based cross-sectional survey 461 participants living urban area (Maroua) and 428 dwellers living in rural area (Tokombere) aged at least 18 years, using a multistage-cluster sampling frame. In all participants, we recorded sociodemographic, medical history, clinical data and fasting blood (capillary) glucose (FBG). Diabetes was considered for FBG ≥ 126 mg/dL or being on glucose-lowering medications, and impaired fasting glycemia (IFG) for FBG 100 - 125 mg/dL. Results: The overall age-standardized prevalence of GHA, IFG and diabetes was 33.6%, 21.7% and 11.9%, respectively. Those data were similar between urban and rural areas. Determinants of GHA were age, overweight/obesity, abdominal obesity and hypertension. IFG was only related to abdominal obesity, while diabetes was related to age, family history of diabetes, overweight/obesity, abdominal obesity and hypertension. Conclusion: Glucose homeostasis abnormalities are alarmingly high in Far North Cameroon. Efforts are needed to promote healthier lifestyles and initiate diabetes-screening campaigns in Cameroon.展开更多
