Prevalence and components of metabolic syndrome in HIV-infected patients at the Tiko Central Clinic and Cottage Hospital in Cameroon

Background HAART and HIV related metabolic syndrome (MS) is associated with increased cardiovascular risk in aging HIV patients. This study was aimed at comparing the prevalence of MS between HIV-infected patients on HAART and apparently healthy HIV-uninfected individuals and identifying key MS components in these groups of subjects.

Methods This was a hospital-based case-control study. The cases were HIV sero-positive individuals on HAART for at least 6 months and controls were HIV sero-negative individuals.

Results 74/135 (54.8%) participants were females amongst which 53/75 (70.7%) and 21/60 (35%) were in the test and control groups respectively. The prevalence of MS was insignificantly higher in HIV-infected patients on HAART than in control subjects according to the IDF (22.7% versus 20%, p=0.834) and NCEP ATP III criteria (18.7% versus 18.3%, p=1.000) respectively. The most prevalent components of MS in HIV-infected patients on HAART were low HDL-c (100%), abdominal obesity (IDF: 68%, ATP III: 32%), and hypertension (28%). Multivariate analysis of MS components in HIV-infected patients on HAART revealed that hypertension (OR: 15.996, 95% CI: 3.385-75.585; p≤0.001) and high blood glucose (OR: 10.760, 95% CI: 1.642-70.505; p=0.013) were associated with MS. Significantly more HIV-infected females were seen with abdominal obesity than HIV-infected males (86.8% versus 4.5%, p≤0.001).

Conclusions Abdominal obesity is a driving component of MS in HIV-infected patients particularly among females and hypertension is a prevalent and predictor component of MS among HIV patients.
