Primary headache disorders among people living with HIV in Lusaka, Zambia

We completed a cross-sectional survey study to determine headache prevalence and its association with HIV characteristics among people living with HIV (PLHIV) in Lusaka, Zambia.

Headaches are common but their association with HIV status is unknown.

The HARDSHIP survey, a headache epidemiology questionnaire previously validated in Zambia, was distributed during a 3-month period to 3666 consecutive adult PLHIV attending routine clinic appointments at the Adult Infectious Diseases Centre at the University Teaching Hospital in Lusaka, Zambia. HIV disease characteristics were abstracted from their charts.

1015 (27.7%) participants responded to the survey. Adjusted for age, 64% reported having a headache within the last year unrelated to another illness. Among participants, 201 met criteria for migraine (20%), 259 for tension-type headache (26%), 18 for probable medication-overuse headache (2%), and 121 for undetermined headache (12%). Prevalence for tension-type headache was significantly higher than that of migraine (P < 0.001). After adjusting for age and sex, higher CD4 counts were associated with migraine. No other associations were observed between overall headache or headache type with HIV disease characteristics including CD4 count, viral load, antiretroviral regimen, and time since HIV diagnosis.

Headaches are highly prevalent among this cohort of PLHIV in Zambia. Optimizing headache treatment and integrating it into routine HIV care may improve quality of life for a substantial proportion of PLHIV in Zambia.
