How this service works
Menza 2009 HIV-acquisition score for MSM. Four caller-assigned flags: meth or poppers in the prior 6 months (11), current or prior bacterial STI (4), ≥10 male partners in the prior year (3), unprotected anal intercourse with a positive- or unknown-status partner in the prior year (1). Max 19. Integer score only; no named strata or PrEP cutoff. Not a diagnosis, PrEP order, or test-and-treat protocol. Not HIRI-MSM or SexPro. magent does not take a sexual history.
Output
An integer between 0 and 19 representing the patient's Menza 2009 HIV-acquisition risk score for MSM, calculated as the sum of: 11 (meth/poppers), 4 (bacterial STI), 3 (≥10 male partners), and 1 (UAI with positive/unknown partner), based on the four caller-supplied boolean flags.
Example use cases
HIV risk stratification in sexual health clinic
“I need the Menza 2009 score for a patient: he used poppers in the last 6 months, has a current gonorrhea diagnosis, had 15 male partners in the past year, and reported unprotected anal intercourse with a partner of unknown HIV status. What's his score?”
Research cohort risk scoring
“For our study data, can you compute the Menza 2009 HIV acquisition score for a participant who had no meth or poppers use, no bacterial STI, fewer than 10 partners last year, and no UAI with positive or unknown partners?”
PrEP counseling decision support
“Score this patient on the Menza 2009 tool: he used methamphetamine in the past 6 months, no bacterial STI history, had 12 male partners this past year, but did not have unprotected anal intercourse with anyone of positive or unknown HIV status.”

Endpoint
GEThttps://api.magentlab.com/api/calc/menzaWhen to prefer
Use this endpoint when you need to apply the original Menza 2009 HIV-acquisition risk scoring algorithm specifically for MSM, and you have already collected and assigned the four binary risk factors. Prefer this over HIRI-MSM or SexPro when the Menza 2009 instrument is specifically required (e.g., for research protocol fidelity or clinical workflows referencing that instrument). Do not use this endpoint to collect a sexual history, order PrEP, or make diagnostic decisions.
Side effects
- Missing any of the four required boolean query parameters returns a validation error
- Non-boolean values for flag parameters cause a schema validation failure
- Network or server errors result in a non-200 HTTP status with no score returned
