Background
HIV and certain antiretrovirals (ARVs) are associated with diabetes. Few studies have examined the prevalence of and factors associated with diabetes amongst HIV-infected individuals on combination antiretroviral therapy (cART) in sub-Saharan Africa; some report prevalence estimates between 3.5–26.5% for diabetes in Cameroon and 20.2–43.5% for prediabetes in sub-Saharan Africa.
Methods
In a cross-sectional study, HIV-infected individuals (16–65 years old) were screened for diabetes using haemoglobin A1C (HbA1C). We further categorized HbA1C as normoglycemia (HbA1C <5.7%), prediabetes (HbA1C 5.7–6.4%), or diabetes (HbA1C≥6.5%). Dysglycemia was defined as HbA1C ≥5.7%. Logistic regression modeling was used to assess factors associated with having dysglycemia..
Results
Of 500 participants, 363 (72.6%) were female. Median age was 42.5 years [Interquartile Range (IQR):36.5–49.5]. Nineteen (3.8%) were diabetic, and 170 (34%) were prediabetic. One hundred nine (22%) had a CD4+ count ≤200 cells/mm3, and 464 (93%) had received ≥28 days of antiretroviral therapy (ART) at time of screening. Median abdominal circumference for women was 79.5cm (IQR: 75.5–85.3) and for men, 86.5cm (IQR: 81.7–90.5). Adjusting for age, sex, socio-economic status, CD4 cell count, being on cART >28 days, BMI, hypertension, history of hypertension, abdominal circumference, and duration of HIV infection, larger abdominal circumference was associated with higher prevalence of prediabetes or diabetes [adjusted Odds Ratio (aOR)=1.07, 95% Confidence Interval (CI):1.03–1.11], while being on cART (aOR=0.46, CI:0.22–0.99) was associated with lower prevalence.
Conclusions
There was a high prevalence of Cameroonian HIV-infected adults with dysglycemia. Larger abdominal circumference was associated with higher prevalence, while cART was associated with lower prevalence.
