Room: Poster Hall CD
Background: Despite a high incidence of sexually transmitted infections (STIs), sexual behavior among U.S. military personnel remains understudied. Since 2014, the U.S. Military HIV Natural History Study has administered a behavioral questionnaire to a cohort of HIV-infected active-duty (AD) and retired personnel (RP). We compared patterns of risk behavior between AD and RP.

Methods: Male participants who completed a behavioral questionnaire (n=1,465) were included in this study. Chi-square and stepwise logistic regression were used to compare AD with RP. Our model included all behavioral variables listed below with adjustment for age and race. We assumed a priori that duty status would be correlated with age and selected the former as our variable of interest, hypothesizing that AD would engage in a higher number of risk behaviors.

Results: Selected demographics and behavioral data are summarized below.

AD (n=731)


RP (n=734) %

Univariate Odds
(95% CI)

Multivariate Odds (95% CI)


Median Age (IQR)

30 (26,37)

51 (46,57)











Behavioral Data

Consumed > 6 drinks on a single occasion (past year)



2.2 (1.7,2.8)

Ever experienced injury from drinking



2.0 (1.6,2.6)

Ever used hard drugs



0.4 (0.3,0.5)

0.5 (0.3,0.9)

High self-perceived risk for STI



1.3 (1.0,1.6)

> 2 new sexual partners in past three months



1.7 (1.3,2.3)

Ever had sex with woman



0.4 (0.3,0.5)

Ever had sex with man



1.2 (0.9,1.5)

Condomless anal intercourse in last 3 mos (casual partner)



1.1 (0.8,1.5)

Condomless anal intercourse in last 3 mos (anonymous partner)



1.3 (0.9,1.8)

AD had significantly (p<0.01) higher rates of gonorrhea (6.4) and chlamydia (6.0) per 100 person-years (py) than RP (2.2 and 1.6, respectively); syphilis rates did not differ between the groups (AD 1.2/100 py; RP 1.3/100 py).

Conclusion: In contrast with our hypothesis, we found a high prevalence of sexual risk behavior among both AD and RP, and only lifetime use of hard drugs was independently associated with duty status. Despite high STI rates, ~20% in either group reported high self-perceived risk for STIs and/or recent condomless sex with an anonymous partner. Our findings demonstrate a need for intensive STI screening and counseling among HIV-infected military personnel in multiple career stages.
