IntroductionRates of sexually transmitted infections (STIs) are higher among U.S. military personnel than their civilian counterparts. Yet there is a paucity of military-specific research that has utilized theoretical frameworks to describe the relative influence of the multiple and interrelated risk factors associated with STIs in this population of young, healthy men and women. The aim of this study was to examine the relative influence of Information, Motivation, and Behavioral Skills Model (IMB) factors known to be associated with condom use and STI diagnosis, as well as examine gender differences among a cohort of young, active duty enlistees who are in the very early stages of their military careers.Materials And MethodsData were collected in 2011 to 2013 through self-administered questionnaires and laboratory-confirmed tests of STIs. Logistic regression analyses were used to assess IMB constructs, behavioral risk variables, and sociodemographic factors associated with STI diagnosis and condom use separately among female and male military personnel.ResultsSTIs among males were significantly associated with nonwhite race, lower STI behavioral intentions and STI behavioral skills, and engaging in sex after drinking alcohol. Further, males who reported more positive attitudes toward using condoms, higher confidence in preventing drinking, higher alcohol prevention norms among peers, a lower frequency of drinking alcohol before engaging in sexual intercourse, more sexual partners, and higher STI behavioral intentions were significantly more likely to report using condoms consistently during sexual encounters. Among female participants, a history of STIs was significantly associated with higher numbers of reported sexual partners and greater alcohol prevention efficacy while lifetime consistent condom use was significantly associated only with stronger intentions to avoid behaviors that might result in STI acquisition.ConclusionOur findings support the need for development of STI prevention strategies that include education and skills-building approaches to reduce alcohol misuse among enlisted military personnel, and especially male personnel. Such programs should include factors that uniquely influence the experiences of males and females in the military context.© The Association of Military Surgeons of the United States 2021.
