Metabolic Syndrome in People Living with Human Immunodeficiency Virus: An Assessment of the Prevalence and the Agreement between Diagnostic Criteria

Abstract EN

Objectives.

We determined metabolic syndrome (MetS) prevalence and assessed the agreement between different diagnostic criteria in HIV-infected South Africans.

Method.

A random sample included 748 HIV-infected adult patients (79% women) across 17 HIV healthcare facilities in the Western Cape Province.

MetS was defined using the Joint Interim Statement (JIS 2009), International Diabetes Federation (IDF 2005), and Adult Treatment Panel III (ATPIII 2005) criteria.

Results.

Median values were 38 years (age), 5 years (diagnosed HIV duration), and 392 cells/mm3 (CD4 count), and 93% of the participants were on antiretroviral therapy (ART).

MetS prevalence was 28.2% (95%CI: 25–31.4), 26.5% (23.3–29.6), and 24.1% (21–27.1) by the JIS, IDF, and ATPIII 2005 criteria, respectively.

Prevalence was always higher in women than in men (all p<0.001), in participants with longer duration of diagnosed HIV (all p≤0.003), and in ART users not receiving 1st-line regimens (all p≤0.039).

The agreement among the three criteria was very good overall and in most subgroups (all kappa≥0.81).

Conclusions.

The three most popular diagnostic criteria yielded similarly high MetS prevalence in this relatively young population receiving care for HIV infection.

Very good levels of agreement between criteria are unaffected by some HIV-specific features highlighting the likely comparable diagnostic utility of those criteria in routine HIV care settings.
