Steering Together in a New Direction: Reducing the Risk of HIV/STD Among African American Men

HIV/AIDS has had a devastating impact on African Americans, who have the highest rates of
HIV/AIDS as compared with Whites, Hispanics, Asians, and Native Americans. Although African
Americans comprise only 13% of the US population, more than 40% of people living with
HIV/AIDS in the US are African American—some 192,277 people. New diagnoses of HIV/AIDS
underscore the epidemic's impact on African Americans. Almost 50% of the people newly
diagnosed with HIV/AIDS in the 33 states with confidential name-based HIV infection
reporting in 2006 were African Americans. The overall rate of newly diagnosed cases was 19
cases per 100,000, but among African Americans, it was 68 per 100,000. The estimated rates
of HIV/AIDS in 2006 were higher among African American men (121 per 100,000) as compared
with White men (17 per 100,000), Latino/Hispanic men (51 per 100,000), and African American
women (57 per 100,000). Heterosexual exposure is a key HIV transmission category among
African Americans. To be sure, the largest number of estimated cases of HIV/AIDS among
African American men fell in the men who have sex with men (MSM) HIV-transmission category.
However, the second largest number of cases was attributed to heterosexual transmission,
with the injection-drug-use HIV-transmission category ranking third. Moreover, heterosexual
exposure was a more important HIV-transmission category among African American men than
among other men. It accounted for 23% of HIV/AIDS cases among African American men, but 19%
among Hispanic men and only 7% of cases among White men. Furthermore, among African American
women, who comprised over 60% of the women with HIV/AIDS in 2006, heterosexual exposure was
by far the most important transmission category, accounting for 83% of cases. Heterosexual
exposure is especially important in Philadelphia, PA, where the proposed study will be
conducted. According to the Philadelphia Department of Public Health, among African American
men, heterosexual exposure surpassed male-to-male contact as the modal exposure category in
2006, 2007, and 2008.

Furthermore, another important health disparity affecting African Americans particularly in
urban areas is the high rate of sexually transmitted disease (STD). About 47% of the cases
of Chlamydia trachomatis (CT) reported to Centers for Disease Control and Prevention (CDC)
in 2006 occurred in African Americans. The CT rate was 7 times higher among African American
women than among White women. The Neisseria gonorrhea rate was 25 times higher among African
American men than among White men and 14 times higher among African American women than
among their White counterparts. Despite the high rate of heterosexual exposure to HIV and
the high rates of other STDs in African American men and women, little research has focused
on interventions targeting heterosexually active men.

Sexual Risk Behavior among Heterosexually Active African American Men

Two key behaviors that increase risk of STD, including HIV, are failing to use condom
consistently and having multiple sexual partners. Although unmarried African American men
were more likely to report consistent condom use than were their Hispanic or White
counterparts, which may reflect recognition of higher risk of STD among African American
men, a large percentage of African American men (47%) risked exposure to HIV and other STDs.
Moreover, consistent condom use declined substantially with increasing age, from 68% in
those 15 to 19 years of age, to 31% in those 25 to 29 years of age, and to only 26% in those
40 to 44 years of age. In the National Survey of Family Growth, among men 15-44 years of
age, unmarried African American men were more likely to have had 4 or more partners in the
past year (13%) compared with White (6%) and Hispanic men (7%).

Interventions to Reduce Risk of Heterosexual Transmission of HIV in African American Men

Whether one considers the domestic or international literature, few randomized controlled
trials (RCTs) of interventions have focused on risk of heterosexual transmission of HIV
among men. Of particular concern is the paucity of trials on the efficacy of risk-reduction
interventions specifically targeting African American men. A systematic review of HIV/STD
risk-reduction interventions found that only 12 of 1157 intervention studies worldwide were
conducted on males only, and only 4 focused exclusively on African American adult men. A
more recent review of interventions to reduce heterosexual transmission of HIV among African
Americans identified 38 RCTs, but only 7 targeted males only and 2 of the 7 focused on
adolescent boys. Thus, only 5 of the 38 trials focused specifically on African American men.
Combining the studies identified in these 2 reviews yields only 6 trials specifically on
heterosexual transmission among African American adult men and only 1 focused on the general
population of heterosexual men. A recent clinic-based study on 266 African American men 18
to 29 years of age diagnosed with an STD is more encouraging. At 3-month follow-up, those
randomized to a single session one-on-one intervention reported fewer unprotected sex acts
than did those who received standard clinical care. In addition, medical-records review
revealed that the intervention participants were less likely to acquire a new STD by 6
months post-intervention than were the control men. Although the few existing studies are an
important first step in beginning to develop interventions for African American men, there
is still an important gap in the literature as noted by Seal and Ehrhardt who asserted that
heterosexual men's sexual and reproductive health is often exclusively viewed in the context
of their female partners. They called for interventions that focus on men's health and
consider men's heterosexual behavior as a starting point in intervention development.

Sustaining Intervention-Induced Behavior Change

As evidence accumulates for the benefits of behavioral interventions it is also clear that
often the effects are short lived. The present study will test the efficacy of a relatively
inexpensive strategy to sustain behavior change. Many strategies have been employed. The
inclusion of booster sessions in intervention programs has been suggested as a strategy to
extend their effects, a strategy consistent with relapse prevention approaches that have
been employed in substance-abuse reduction and smoking cessation programs. Several HIV
risk-reduction intervention studies have incorporated boosters in their interventions, but
the existing studies do not provide clear evidence for the efficacy of boosters per se,
because they were not designed to compare the effects of an HIV/STD risk-reduction
intervention with a booster to the effects of that same intervention without the booster. In
addition to booster sessions, there may be other effective methods for extending
intervention effects. Telephone counseling programs have been shown to help smokers who are
in the process of quitting. Periodic mailings have also been found to be more effective than
a telephone hot line in preventing relapse among former cigarette smokers.

This study will test whether text messages extend an HIV risk-reduction intervention's
efficacy. The use of text messaging has several advantages. It is relatively inexpensive,
possibly even more cost effective than other phone or print-based interventions.
Participants do not have to return for another intervention session, facilitators do not
have to conduct the sessions, and no space must be made available. Text messages are
delivered almost immediately and can be stored in the recipient's phone, accessible at a
time that suits him. Tailored messages are more efficacious than untailored messages, and
text messages can be individually tailored to promote condom use to men who fail to use them
for different reasons. Pew surveys reveal that a great majority of African Americans own
cell phones, African Americans are more intense and frequent users of all the phones'
capabilities than are Whites, and more African Americans than Whites use text messaging.
Although RCTs of text-messaging interventions have reported significant effects on healthful
behaviors, including reduced cigarette smoking, increased adherence to insulin regimens in
diabetics, and increased medical appointment keeping, no trials have examined whether text
messaging can enhance the efficacy of an HIV risk-reduction intervention.

The study will utilize a RCT design. Participants will be recruited through advertising in a
local free newspaper, through community based organizations that serve African Americans,
through recruitment flyers at universities, bars, health clubs, and health fairs, and
through face-to-face recruitment at social and sports events and activities expecting a high
turnout of African American men. Computer-generated random number sequences will be used to
randomize them to the Steering Together in a New Direction (STAND) HIV Risk Reduction
Intervention or a No-Intervention Control Condition and to receive or not receive a Text
Messaging Intervention. Participants will complete assessments via audio computer-assisted
self-interviewing before the intervention and immediately post and 6 and 12 months
post-intervention administered by data collectors blind to the participants randomly
assigned condition. The trial will test whether the STAND intervention increases the
consistent use of condoms and decreases other sexual risk behaviors compared with the
no-intervention control group, whether the text messages are efficacious, and whether the
efficacy of the STAND intervention is enhanced among men who receive the text messages.
