Within the Hidden Epidemic: Sexually Transmitted Diseases and HIV/AIDS Among American Indians and Alaska Natives

Examining the Association Between Affordable Care Act Medicaid Expansion and Sexually Transmitted Infection Testing Among U.S. Women

INTRODUCTION

Sexually transmitted infection (STI) rates are rising among women in the United States, increasing the importance of routine STI testing. Beginning in 2014, some states expanded Medicaid under the Affordable Care Act, providing health coverage to most individuals in and near poverty. Here, we investigate whether Medicaid expansion changed rates of STI testing among U.S. women.

METHODS

We analyzed nationally representative 2011-2017 National Survey of Family Growth data from U.S. women ages 15-44. Using difference-in-differences analysis, we assessed whether Medicaid expansion was associated with within-state changes in the prevalence of STI testing in the past 12 months, among women overall and by race/ethnicity and sexual orientation, during each year following Medicaid expansion. Models were adjusted for individual- and state-level demographic and socioeconomic factors.

RESULTS

Our sample included 14,196 U.S. women. Medicaid expansion was associated with higher STI testing rates, which increased over time. By 3 years post-expansion, expansion states had increased STI testing by 12.7 percentage points more than nonexpansion states (95% confidence interval [CI] [2.5, 23.0], p = .016). This association was imprecisely estimated within racial/ethnic and sexual orientation subgroups, but trended strongest among white, Latina, and heterosexual women, followed by Black and bisexual women (who tested more often at baseline).

CONCLUSIONS

Medicaid expansion is associated with increased STI testing among U.S. women; these benefits grew over time but varied by both race/ethnicity and sexual orientation. State governments that fail to expand Medicaid may harm their residents' health by allowing more spread of STIs.

Predictors of STD Screening From the Indigenist Stress-Coping Model Among Native Adults With Binge Substance Use

Objective

The American Indian/Alaska Native (AI/AN) population in the U.S. is thriving in spite of settler colonialist efforts of erasure. AI/AN people, however, continue to experience persistent health disparities including a disproportionate burden of substance use and sexually transmitted diseases/infections (STDs/STIs), as well as a disproportionate lack of public health STD screening services and STD prevention interventions grounded in AI/AN social contexts, experiences, and epistemologies. The present study explored how stressors and protective factors based on the Indigenist Stress Coping framework predict STD screening outcomes among Native adults.

Methods

We analyzed baseline self-report data from 254 Native adults ages 18-55 years with recent binge substance use who were enrolled in an evaluation of "EMPWR," a two-session STD risk reduction program in a rural, reservation-based community in the U.S. Southwest. Logistic regression models with robust variance were used to estimate odds ratios of lifetime STD testing for the theoretical stressors and cultural buffers.

Results

A little over half the sample were males (52.5%, n = 136), with a mean age of 33.6 years (SD = 8.8). The majority (76.7%, n = 195) reported having ever been screened for STD in their life. Discrimination score were significantly associated with lifetime STD testing: The higher discrimination was associated with lower odds of STD testing in the fully adjusted model (aOR = 0.40, 95%CI: 0.18, 0.92). The effects of AI/AN-specific cultural buffer such as participation in traditional practices on STD testing outcomes was in the expected positive direction, even though the association was not statistically significant. Household size was significantly associated with STD screening: The higher the number of people lived together in the house, the higher the odds of STD testing in the fully adjusted model (aOR = 1.19, 95%CI: 1.04, 1.38).

Conclusion

Our findings suggest that STD prevention programs should take into consideration AI/AN-specific historical traumatic stressors such as lifetime discrimination encounters and how these interact to drive or discourage sexual health services at local clinics. In addition, larger household size may be a protective factor functioning as a form of social support, and the extended family's role should be taken into consideration. Future research should consider improvement in measurements of AI/AN enculturation constructs.

Vaginal microbiota of American Indian women and associations with measures of psychosocial stress

Molecular-bacterial vaginosis (BV) is characterized by low levels of vaginal Lactobacillus species and is associated with higher risk of sexually transmitted infections (STI). Perceived psychosocial stress is associated with increased severity and persistence of infections, including STIs. American Indians have the highest rates of stress and high rates of STIs. The prevalence of molecular-BV among American Indian women is unknown. We sought to evaluate measures of psychosocial stress, such as historic loss (a multigenerational factor involving slavery, forced removal from one's land, legally ratified race-based segregation, and contemporary discrimination) and their association with the vaginal microbiota and specific metabolites associated with BV, in 70 Northwestern Plains American Indian women. Demographics, perceived psychosocial stressors, sexual practices, and known BV risk factors were assessed using a modified version of the American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project survey. Self-collected mid-vaginal swabs were profiled for bacterial composition by 16S rRNA gene amplicon sequencing and metabolites quantified by targeted liquid-chromatography mass spectrometry. Sixty-six percent of the participants were classified as having molecular-BV, with the rest being either dominated by L. crispatus (10%) or L. iners (24%). High levels of lifetime trauma were associated with higher odds of having molecular-BV (adjusted Odds Ratio (aOR): 2.5, 95% Credible Interval (CrI): 1.1-5.3). Measures of psychosocial stress, including historic loss and historic loss associated symptoms, were significantly associated with lifestyle and behavioral practices. Higher scores of lifetime trauma were associated with increased concentrations of spermine (aFC: 3.3, 95% CrI: 1.2-9.2). Historic loss associated symptoms and biogenic amines were the major correlates of molecular-BV. Historical loss associated symptoms and lifetime trauma are potentially important underlying factors associated with BV.

Impacts of the respecting the circle of life teen pregnancy prevention program on risk and protective factors for early substance use among native American youth

BACKGROUND

Early substance use disproportionately impacts Native American (Native) youth and increases their risk for future abuse and dependence. The literature urges for interventions to move beyond focusing on single risk behaviors (e.g. substance use) and instead have capacity to improve health risk behaviors co-occuring during adolescence, particularly among Native populations for whom few evidence-based interventions (EBI) exist. We evaluated the effectiveness of the Respecting the Circle of Life program (RCL) on risk and protective factors for early substance use. RCL is a culturally tailored EBI shown to improve sexual health outcomes among Native youth.

METHODS

We conducted secondary analyses of data collected through a community-based randomized controlled trial of RCL evaluated among Native youth (ages 11-19) residing on a rural reservation between 2015-2020 (N = 534, 47.4 % male). We used linear regression, controlling for baseline age and sex, to test between study group differences in outcomes at 3-, 9-, and 12-month post-intervention. Models were stratified by sex and age (11-12, 13-14, and 15+ years of age) to examine differences within these subgroups.

RESULTS

Youth receiving RCL reported lower intention to use substances through 12-months follow-up (p = 0.006). Statistically significant improvements were also observed across peer, parent, and sexual partner risk and protective factors to delay substance use initiation, with notable differences among boys and participants ages 13-14.

CONCLUSIONS

RCL is a primary prevention, skills-based program effective in preventing risks for substance use. This evaluation underscores the value in developing programs that influence concurrent adolescent risk behaviors, especially for Native communities who endure multiple health disparities.

Prevention of Sexually Transmitted Diseases and Pregnancy Prevention Among Native American Youths: A Randomized Controlled Trial, 2016-2018

Objectives. To evaluate the efficacy of the Respecting the Circle of Life program (RCL) among Native American youths 11 to 19 years of age residing in a rural reservation community in the southwestern United States. Methods. Between 2016 and 2018, we conducted a randomized controlled trial of the RCL program with 534 Native youths. Participants completed assessments at baseline and 9 and 12 months after the intervention. We conducted intention-to-treat analyses based on study group randomization. Results. At 9 months, intervention participants had significantly better condom use self-efficacy (P < .001), higher intentions to use condoms (P = .024) and abstain from sex (P = .008), and better contraceptive use self-efficacy (P < .001) than control participants, as well as better condom use (P = .032) and contraceptive use (P = .002) negotiation skills. At 12 months, intervention participants had significantly better sexual and reproductive health knowledge (P = .021), condom use self-efficacy (P < .001), contraceptive use self-efficacy (P < .001), and contraceptive use negotiation skills (P = .004) than control participants. Intervention participants reported significantly more communication with their parents about sexual and reproductive health than control participants at both 9 and 12 months (P = .042 and P = .001, respectively). Conclusions. The RCL program has a significant impact on key factors associated with pregnancy prevention among Native youths and should be used as an adolescent pregnancy prevention strategy. Trial Registration.  Clinical Trials.gov identifier: NCT02904629. (Am J Public Health. 2021;111(10): 1874-1884. https://doi.org/10.2105/AJPH.2021.306447).

Assessment of the Reach, Usability, and Perceived Impact of "Talking Is Power": A Parental Sexual Health Text-Messaging Service and Web-Based Resource to Empower Sensitive Conversations with American Indian and Alaska Native Teens

BACKGROUND

Early sexual debut among American Indian and Alaska Native (AI/AN) adolescents has been associated with an increased risk of teenage pregnancies and sexually transmitted infections, along with an increased risk of having multiple lifetime sexual partners, and engaging in greater frequency of sex, substance abuse, and lack of condom use. A major protective factor against early sexual debut among AI/AN youth is the familial system. Interventions aiming to improve parent-child communication and parental warmth toward adolescent sexual health topics were reported to contribute to positive youth sexual health outcomes, specifically among minority youth. Healthy Native Youth thus developed the Talking is Power text-messaging service to guide parents and caring adults on how to initiate sensitive topics with youth and how to support them in making informed decisions regarding sex and healthy relationships.

METHODS

Descriptive statistics were used to demonstrate website analytics and reach per views and time spent on each page, and for displaying participants' responses to the questions on the usability of the Talking is Power text-messaging series. To assess the perceived impact of the series, the differences in mean percentage scores of the question assessing parental comfort in engaging in sexual health topics with youth between pre- and post-intervention were calculated using two-sample t-tests of equal variances. Descriptive content analysis was adopted to highlight emerging themes from open-ended items.

RESULTS

When looking at reach, 862 entrances were recorded during the specified time period (5.8% of total entrances to HNY website), while the bounce rate was set at 73.1% (22.6% greater than the industry average), and the exit rate was 54.3% (15.2% greater than the industry average). Series usability was highly ranked on the 5-Likert scale in terms of signing up for a similar series on a different topic, quality of images, texts, and links, relating to prompts, and change in sparking sensitive conversations with youth. High likelihood of recommending the series to a friend or colleague was also reported by participants (0-10). No significant difference in parental comfort levels was reported (p = 0.78 > 0.05). Main themes provided suggestions for improving the series mode of delivery, while others included positive feedback about the material, with the possibility of expanding the series to other adolescent health topics.

CONCLUSION

Lessons learned during the design, dissemination, and evaluation of the resource's usability, reach, and perceived impact may be of interest to other Indigenous communities who are in the process of adapting and/or implementing similar approaches.

Empowering our people: Predictors of retention in an STI risk reduction program among rural Native Americans with binge substance use

PURPOSE

Substance use and sexual risk-taking have been shown to co-occur. Programs focused on sexually transmitted infections (STIs) reduction may benefit substance-using, particularly binge substance-using, adults. This is especially true for rural Native American communities who endure sexual and substance use disparities and have few STI risk reduction programs. This study explores factors predicting retention in an STI risk reduction program among rural Native adults engaged in binge substance use.

METHODS

We analyzed data from 150 Native adults ages 18-55 participating in an evaluation of "EMPWR," a 2-session STI risk reduction program in a rural, reservation-based community. Multivariate logistic regression models were used to estimate associations between independent variables and program completion across demographics, sexual behaviors, substance use behaviors, mental health, recent health care utilization, and perceived enculturation and discrimination.

FINDINGS

The sample was 49.2% (n = 59) female with a mean age of 33.61 years (SD = 8.25). Twenty-six completed only the first EMPWR session, 94 completed both EMPWR sessions, and 30 were randomized but completed 0 sessions. Being married/cohabiting (adjusted odds ratio [AOR] = 6.40, P = .0063) and living with an older generation (AOR = 4.86, P = .0058) were significantly associated with higher odds of completing EMPWR.

CONCLUSIONS

Findings provide insight on factors driving retention of Natives with recent binge substance use in STI risk reduction programming. An important contribution to Native health literature is that living with an older generation positively predicted EMPWR program completion, suggesting that STI risk reduction programs should harness the strength of families to ensure program attendance and optimize impacts in rural reservation contexts.

"Automatic assumption of your gender, sexuality and sexual practices is also discrimination": Exploring sexual healthcare experiences and recommendations among sexually and gender diverse persons in Arctic Canada

Sexual and mental health disparities are reported in Arctic Canada as in other Arctic regions that experience shared challenges of insufficient healthcare resources, limited transportation, and a scarcity of healthcare research. Lesbian, gay, bisexual, transgender, and queer persons (LGBTQ+) report sexual and mental health disparities in comparison with their heterosexual and cisgender counterparts, and these disparities may be exacerbated in rural versus urban settings. Yet limited research has explored sexual healthcare experiences among LGBTQ+ persons in the Arctic who are at the juncture of Arctic and LGBTQ+ health disparities. We conducted a qualitative study from May 2015 to October 2015 with LGBTQ+ persons in the Northwest Territories, Canada that involved in-depth individual interviews with LGBTQ+ youth (n = 16), LGBTQ+ adults (n = 21), and key informants (e.g. coaches, teachers, nurses, social workers, and healthcare providers) (n = 14). We conducted thematic analysis, a theoretically flexible approach that integrates deductive and inductive approaches, to identify and map themes in the data. Findings reveal geographical, social, and healthcare factors converge to shape healthcare access. Specifically, the interplay between heterosexism and cisnormativity, intersectional forms of stigma, and place limited LGBTQ+ persons' sexual healthcare access and produced negative experiences in sexual healthcare. Limited healthcare facilities in small communities resulted in confidentiality concerns. Heteronormativity and cisnormativity constrained the ability to access appropriate sexual healthcare. LGBTQ+ persons experienced LGBTQ+, HIV, and sexually transmitted infections stigma in healthcare. Participants also discussed healthcare provider recommendations to better serve LGBTQ+ persons: non-judgment, knowledge of LGBTQ+ health issues, and gender inclusivity. Findings can inform multi-level strategies to reduce intersecting stigma in communities and healthcare, transform healthcare education, and build LGBTQ+ persons' healthcare navigation skills.

Exploring the Role of Sex and Sexual Experience in Predicting American Indian Adolescent Condom Use Intention Using Protection Motivation Theory

Introduction: American Indian (AI) youth experience poor sexual health outcomes. Research indicates the Protection Motivation Theory (PMT) is a robust model for understanding how sexual risk and protective behaviors are associated with condom use intention (CUI). Studies indicate the constructs of the PMT which influence CUI vary by sex and sexual experience. This analysis explores associations between PMT constructs and CUI by sex and sexual experience among AI youth who participated in the Respecting the Circle of Life (RCL) trial, a sexual and reproductive health intervention. Methods: We analyzed baseline data from the sample of 267 AIs, ages 13-19, who participated in the evaluation. We examined CUI and PMT construct scores by sex and sexual experience utilizing generalized estimated equations and multiple regression models to test which PMT constructs were associated with CUI across sex and sexual experience. Results: Twenty-two percentage of participants were sexually experienced; 56.8% reported CUI at baseline. We found several differences in scores in PMT constructs by sex and sexual experience including self-efficacy, response efficacy, vulnerability, severity, and extrinsic rewards. We also found constructs varied that were associated with CUI varied across sex and sexual experience. No PMT constructs were associated with CUI among sexually experienced youth. Conclusion: Results provide support for developing, selecting and delivering sexual health programs by sex and sexual experience in American Indian communities. Girls programs should focus on internal satisfaction and self-worth while boys should focus on negative impacts of not using condoms. Programs for youth who are not sexually active should focus on negative impacts of not using condoms. Programs for sexually inactive youth should work to change peer norms around condom use and improve knowledge about the efficacy of condom use.

Risk and Protective Factors Associated With Lifetime Sexual Experience Among Rural, Reservation-Based American Indian Youth

Early sexual initiation is a catalyst for sexually transmitted infection and unintended pregnancy. American Indian/Alaska Native (AI/AN) youth initiate sex prior to age 13 more often than other U.S. youth, contributing to current inequalities in sexual health. Identifying what factors were associated with lifetime sexual experience among AI/AN youth can inform the development of primary prevention programming to delay sexual initiation, alleviate the costs of early sexual activity, and improve sexual health outcomes in this population. We analyzed cross-sectional data from 267 AI youth ages 13-19, recruited from a rural, reservation-based community. We used multivariate logistic regression models to estimate associations between independent variables and lifetime sexual experience (vaginal and/or anal sex) across the following categories: sociodemographic, knowledge, attitudes/perceptions, beliefs, intentions, skills, behaviors, and theoretical constructs. The sample was 56.2% female, mean age 15.1 years (SD = 1.7), and 22.5% were sexually experienced. In our final model, condom use self-efficacy (attitude/perception factor) and intentions to remain abstinent until marriage (intention factor) were associated with lower odds of lifetime sexual experience. Age (sociodemographic factor), intention to have sex (intention factor), use of any contraception (behavior factor), and higher response efficacy (theoretical construct) were associated with lifetime sexual experience. Of these, intention to have sex was the strongest indicator. These results both corroborate and contrast with other research conducted among rural, reservation-based AI/AN youth. Our findings show programs targeting intentions may have the greatest impact among reservation-based AI youth, and justify program delivery stratified by age group in this setting.

Abuse of power in relationships and sexual health

STI rates are high for First Nations in Canada and the United States. Our objective was to understand the context, issues, and beliefs around high STI rates from a nêhiyaw (Cree) perspective. Twenty-two in-depth interviews were conducted with 25 community participants between March 1, 2011 and May 15, 2011. Interviews were conducted by community researchers and grounded in the Cree values of relationship, sharing, personal agency and relational accountability. A diverse purposive snowball sample of community members were asked why they thought STI rates were high for the community. The remainder of the interview was unstructured, and supported by the interviewer through probes and sharing in a conversational style. Modified grounded theory was used to analyze the narratives and develop a theory. The main finding from the interviews was that abuse of power in relationships causes physical, mental, emotional and spiritual wounds that disrupt the medicine wheel. Wounded individuals seek medicine to stop suffering and find healing. Many numb suffering by accessing temporary medicines (sex, drugs and alcohol) or permanent medicines (suicide). These medicines increase the risk of STIs. Some seek healing by participating in ceremony and restoring relationships with self, others, Spirit/religion, traditional knowledge and traditional teachings. These medicines decrease the risk of STIs. Younger female participants explained how casual relationships are safer than committed monogamous relationships. Resolving abuse of power in relationships should lead to improvements in STI rates and sexual health.

HIV, Chlamydia, Gonorrhea, and Primary and Secondary Syphilis among American Indians and Alaska Natives Within Indian Health Service Areas in the United States, 2007-2010

National rates from human immunodeficiency virus (HIV) and sexually transmitted disease (STD) surveillance may not effectively convey the impact of HIV and STDs on American Indian/Alaska Native (AI/AN) communities. Instead, we compared average annual diagnosis rates per 100,000 population of HIV, chlamydia (CT), gonorrhea (GC), and primary and secondary (P&S) syphilis, from 2007 to 2010, among AI/AN aged ≥ 13 years residing in 625 counties in the 12 Indian Health Service Areas, all AI/AN, and all races/ethnicities to address this gap. AI/AN comprised persons reported as AI/AN only, with or without Hispanic ethnicity. Out of 12 IHS Areas, 10 had higher case rates for CT, 3 for GC, and 4 for P&S syphilis compared to rates for all races/ethnicities. Eight Areas had higher HIV diagnosis rates than for all AI/AN, but HIV rates for all IHS Areas were lower than national rates for all races/ethnicities. Two IHS Areas ranking highest in rates of CT and GC and four Areas with highest P&S syphilis also had high HIV rates. STD and HIV rates among AI/AN were greater in certain IHS Areas than expected from observing national rates for AI/AN. Integrated surveillance of overlapping trends in STDs and HIV may be useful in guiding prevention efforts for AI/AN populations.

Relationship between a Centers for Disease Control and Prevention expanded HIV testing initiative and past-year testing by race/ethnicity: a multilevel analysis of the Behavioral Risk Factor Surveillance System

The Centers for Disease Control and Prevention's (CDC) expanded testing initiative (ETI) aims to bolster HIV testing among populations disproportionately affected by the HIV epidemic by providing additional funding to health departments serving these communities. ETI prioritizes testing in clinical settings; therefore, we examined the relationship between state-level ETI participation and past-year HIV testing among a racially/ethnically diverse sample of adult respondents to the 2012 Behavioral Risk Factor Surveillance System who accessed health services within the 12 months prior to being interviewed. Controlling for individual- and state-level characteristics in a multilevel logistic regression model, ETI participation was independently and positively associated with past-year testing, but this association varied by race/ethnicity. Hispanics had higher odds (adjusted odds ratio [AOR]: 1.49; 95% CI: 1.11-2.02) and American Indian/Alaska Natives had lower odds (AOR: 0.66; 95% CI: 0.43-0.99) of testing if they resided in states with (vs. without) ETI participation. State-level ETI participation did not significantly alter past-year testing among other racial/ethnic groups. Prioritizing public health resources in states most affected by HIV can improve testing patterns, but other mechanisms likely influence which racial/ethnic groups undergo testing.

HIV Among Indigenous peoples: A Review of the Literature on HIV-Related Behaviour Since the Beginning of the Epidemic

From the early days of the HIV epidemic, Indigenous peoples were identified as a population group that experiences social and economic determinants-including colonialism and racism-that increase exposure to HIV. There are now substantial disparities in HIV rates between Indigenous and non-Indigenous peoples in some countries. We conducted a comprehensive literature review to assess the evidence on HIV-related behaviors and determinants in four countries-Australia, Canada, New Zealand and the United States-in which Indigenous peoples share important features of colonization and marginalization. We identified 107 articles over more than 20 years. The review highlights the determinants of HIV-related behaviors including domestic violence, stigma and discrimination, and injecting drug use. Many of the factors associated with HIV risk also contribute to mistrust of health services, which in turn contributes to poor HIV and health outcomes among Indigenous peoples.

Ectopic pregnancy among American Indian and Alaska Native women, 2002-2009

To examine rates of ectopic pregnancy (EP) among American Indian and Alaska Native (AI/AN) women aged 15-44 years seeking care at Indian Health Service (IHS), Tribal, and urban Indian health facilities during 2002-2009. We used 2002-2009 inpatient and outpatient data from the IHS National Patient Information Reporting System to identify EP-associated visits and obtain the number of pregnancies among AI/AN women. Repeat visits for the same EP were determined by calculating the interval between visits; if more than 90 days between visits, the visit was considered related to a new EP. We identified 229,986 pregnancies among AI/AN women 15-44 years receiving care at IHS-affiliated facilities during 2002-2009. Of these, 2,406 (1.05 %) were coded as EPs, corresponding to an average annual rate of 10.5 per 1,000 pregnancies. The EP rate among AI/AN women was lowest in the 15-19 years age group (5.5 EPs per 1,000 pregnancies) and highest among 35-39 year olds (18.7 EPs per 1,000 pregnancies). EP rates varied by geographic region, ranging between 6.9 and 24.4 per 1,000 pregnancies in the Northern Plains East and the East region, respectively. The percentage of ectopic pregnancies found among AI/AN women is within the national 1-2 % range. We found relatively stable annual rates of EP among AI/AN women receiving care at IHS-affiliated facilities during 2002-2009, but considerable variation by age group and geographic region. Coupling timely diagnosis and management with public health interventions focused on tobacco use and sexually transmitted diseases may provide opportunities for reducing EP and EP-associated complications among AI/AN women.

Post-traumatic stress disorder and HIV risk behaviors among rural American Indian/Alaska Native women

We assessed the relationship between post-traumatic stress disorder (PTSD), binge drinking, and HIV sexual risk behavior by examining number of unprotected sex acts and number of sexual partners in the past 6 months among 129 sexually active American Indian women. A total of 51 (39.5%) young women met PTSD criteria. Among women who met the PTSD criteria, binge drinking was associated with a 35% increased rate of unprotected sex (IRR 1.35, p < .05), and there was a stronger association between increased binge drinking and risk of more sexual partners (IRR 1.21, p < .001) than among women who did not meet PTSD criteria (IRR 1.08, p < .01) with a difference of 13% (p < .05). HIV intervention and prevention interventions in this population likely would benefit from the inclusion of efforts to reduce binge drinking and increase treatment of PTSD symptoms.

Place and sexual partnership transition among young American Indian and Alaska native women

Multiple challenges expose American Indian and Alaska Native (AIAN) women to high-risk sexual partnerships and increased risk for HIV/STI. Using a unique sample of sexually-active young AIAN women (n = 129), we examined characteristics of last three partners and whether transitional partnerships were associated with different risk profiles, including where partners met, lived, and had sex. Respondents were more likely to have met their previous or current secondary partner (P2) at a friend's or family setting (versus work or social setting) (AOR = 3.92; 95 % CI 1.31, 11.70). Condom use was less likely when meeting a partner at friend's or family settings (AOR = 0.17; 95 % CI 0.05, 0.59). Sexual intercourse with P2 (compared to P1) usually took place in "riskier" settings such as a car, bar, or outside (AOR = 4.15; 95 % CI 1.59, 10.68). Perceived "safe" places, e.g., friend's or family's house, were identified with risky behaviors; thus, homogeneous messaging campaigns may promote a false sense of safety.

Hepatitis C virus in American Indian/Alaskan Native and Aboriginal peoples of North America

Liver diseases, such as hepatitis C virus (HCV), are “broken spirit” diseases. The prevalence of HCV infection for American Indian/Alaskan Native (AI/AN) in the United States and Canadian Aboriginals varies; nonetheless, incidence rates of newly diagnosed HCV infection are typically higher relative to non-indigenous people. For AI/AN and Aboriginal peoples risk factors for the diagnosis of HCV can reflect that of the general population: predominately male, a history of injection drug use, in midlife years, with a connection with urban centers. However, the face of the indigenous HCV infected individual is becoming increasingly female and younger compared to non-indigenous counterparts. Epidemiology studies indicate that more effective clearance of acute HCV infection can occur for select Aboriginal populations, a phenomenon which may be linked to unique immune characteristics. For individuals progressing to chronic HCV infection treatment outcomes are comparable to other racial cohorts. Disease progression, however, is propelled by elevated rates of co-morbidities including type 2 diabetes and alcohol use, along with human immunodeficiency virus (HIV) co-infection relative to non-indigenous patients. Historical and personal trauma has a major role in the participation of high risk behaviors and associated diseases. Although emerging treatments provide hope, combating HCV related morbidity and mortality will require interventions that address the etiology of broken spirit diseases.

A cautionary tale: risk reduction strategies among urban American Indian/Alaska Native men who have sex with men

American Indian and Alaska Native (AIAN) men who have sex with men (MSM) are considered particularly high risk for HIV transmission and acquisition. In a multi-site cross-sectional survey, 174 AIAN men reported having sex with a man in the past 12 months. We describe harm reduction strategies and sexual behavior by HIV serostatus and seroconcordant partnerships. About half (51.3%) of the respondents reported no anal sex or 100% condom use and 8% were in seroconcordant monogamous partnership. Of the 65 men who reported any sero-adaptive strategy (e.g., 100% seroconcordant partnership, strategic positioning or engaging in any strategy half or most of the time), only 35 (54.7%) disclosed their serostatus to their partners and 27 (41.5%) tested for HIV in the past 3 months. Public health messages directed towards AIAN MSM should continue to encourage risk reduction practices, including condom use and sero-adaptive behaviors. However, messages should emphasize the importance of HIV testing and HIV serostatus disclosure when relying solely on sero-adaptive practices.

'I've had unsafe sex so many times why bother being safe now?': the role of cognitions in sexual risk among American Indian/Alaska Native men who have sex with men

BACKGROUND

American Indian/Alaska Native (AI/AN) men who have sex with men (MSM) are at high risk of human immunodeficiency virus (HIV) acquisition and transmission.

PURPOSE

This study aimed to investigate a potential area of focus for HIV prevention interventions by assessing the impact of sexual risk cognitions on sexual risk-taking among AI/AN MSM.

METHODS

AI/AN MSM (N = 173) from a national cross-sectional survey were analyzed.

RESULTS

Reporting more frequent sexual risk cognitions overall (high sexual risk cognitions) was associated with multiple HIV risk factors including unprotected anal intercourse and serodiscordant unprotected anal intercourse. Participants with high sexual risk cognitions had a 2.3 (95% Confidence Interval: 1.1, 4.7) times greater odds of engaging in unprotected anal intercourse regardless of childhood sexual abuse, depression, and alcohol dependence. Most individual sexual risk cognitions were associated with unprotected anal intercourse, serodiscordant unprotected anal intercourse, or both.

CONCLUSIONS

Results suggest that sexual risk cognitions may be a productive area for further work on HIV prevention among AI/AN MSM.

Comparison of sexual mixing patterns for syphilis in endemic and outbreak settings

BACKGROUND

In a largely rural region of North Carolina during 1998-2002, outbreaks of heterosexually transmitted syphilis occurred, tied to crack cocaine use and exchange of sex for drugs and money. Sexual partnership mixing patterns are an important characteristic of sexual networks that relate to transmission dynamics of sexually transmitted infections (STIs).

METHODS

Using contact tracing data collected by disease intervention specialists, we estimated Newman assortativity coefficients and compared values in counties experiencing syphilis outbreaks to nonoutbreak counties, with respect to race/ethnicity, race/ethnicity and age, and the cases' number of social/sexual contacts, infected contacts, sex partners, and infected sex partners, and syphilis disease stage (primary, secondary, early latent).

RESULTS

Individuals in the outbreak counties had more contacts and mixing by the number of sex partners was disassortative in outbreak counties and assortative nonoutbreak counties. Although mixing by syphilis disease stage was minimally assortative in outbreak counties, it was disassortative in nonoutbreak areas. Partnerships were relatively discordant by age, especially among older white men, who often chose considerably younger female partners.

CONCLUSIONS

Whether assortative mixing exacerbates or attenuates the reach of STIs into different populations depends on the characteristic/attribute and epidemiologic phase. Examination of sexual partnership characteristics and mixing patterns offers insights into the growth of STI outbreaks that complement other research methods.

Challenges in public health research with American Indians and other small ethnocultural minority populations

As a result of the historical legacy of conquest, colonization, and cultural destruction, indigenous peoples often represent just a small segment of the population in many countries throughout the world. In the United States, American Indians/Alaska Natives are not only one of the smallest minority groups in the nation, but are also very culturally diverse. Disparities in health outcomes often occur along racial and ethnic lines, and culture can play an important role in shaping health behavior. Research on the distribution and patterning of disease and risk behaviors among population subgroups is critical for advancing evidence-based public health policy and practice. This article provides a brief overview of key challenges in conducting behavioral health research with American Indians at both community and population levels. Many of the issues raised also apply to other small ethnocultural minority groups.

Boyfriends and booty calls: sexual partnership patterns among Canadian Aboriginal young people

OBJECTIVES

Sexual partnership patterns, forced sex, and condom non-use can contribute to STI risk, but little is known about these patterns among Aboriginal young people despite elevated STI risk in this group. We describe sexual relationship and condom use patterns among Canadian Aboriginal young people, and how these patterns relate to the socio-structural context as experienced by young people.

METHODS

We use data from in-depth individual interviews conducted in 2004 with 22 young people who reported ever having sex and who self-identified as Aboriginal in British Columbia, Canada. A thematic analysis is presented.

RESULTS

Young people described a range of partnership patterns, including 'on-off' relationships which could have high rates of partner turnover but could sometimes be viewed as acceptable contexts for pregnancy, precluding condom use. Contextual elements beyond individual control appeared to contribute to these patterns. Migration between geographic locations was linked with risky partnership patterns, especially if it was linked with family instability or substance use problems.

CONCLUSION

Sexual health interventions for this group must address partnership patterns in addition to promoting condom use. Survey research into 'migration' as a risk factor for STI transmission should consider reasons for migration. Interventions that address both individual level behaviour and the contextual elements that shape behaviour should be developed and tested.

Sexually transmitted diseases among American Indians in Arizona: an important public health disparity

OBJECTIVE

We conducted an analysis of rates, geographic distribution, and time to treatment of chlamydia, gonorrhea, and early syphilis (ES) among Arizona American Indians (AIs) to address racial disparities affecting this group.

METHODS

We used the Arizona Department of Health Services' sexually transmitted disease (STD) surveillance database to identify STD cases and calculate rates among AIs in Arizona from 2003 to 2007. We mapped AI ES cases reported during that time frame by reported resident ZIP code, calculated days elapsed from specimen collection to initial treatment, and compared rates and time to treatment for AIs with those of non-Hispanic white (NHW) individuals.

RESULTS

Annual Arizona AI STD rates for chlamydia, gonorrhea, and ES from 2003 to 2007 ranged from 2.7 to 7.8 times those of NHW people. During the same time period, the annual rates for all three STDs among adolescents aged 15 to 19 years were also higher among AIs and ranged from 2.0 to 14.8 times those of NHW individuals. The majority of cases for ES reported ZIP codes located in the northeastern and southern central portions of the state. The median time to treatment in AI populations was significantly longer than in NHW populations for chlamydia and gonorrhea, but not for ES.

CONCLUSIONS

High rates of STDs have been identified among AIs in certain regions of Arizona. Additionally, there are significant delays in treatment for gonorrhea and chlamydia. STD prevention and education programs that prioritize this health disparity and promote expeditious screening, diagnosis, and treatment are needed.

Circle of life: rationale, design, and baseline results of an HIV prevention intervention among young American Indian adolescents of the Northern Plains

In spite of significant disparities in sexual health outcomes for American Indian youth, no studies exist examining the effectiveness of HIV-prevention interventions. Circle of Life is an HIV-prevention intervention specifically developed for American Indian middle-school youth. We describe the rationale, methodology, and baseline results of a longitudinal randomized trial of Circle of Life conducted among American Indian youth aged 11-15 in a reservation community. The innovative design includes two pre-intervention waves to determine patterns of behavior prior to the intervention that might be associated with a differential impact of the intervention on sexual risk. We used one-way analysis of variance and chi-square tests to test for significant differences between randomized group assignment at each baseline wave and generalized estimating equations (GEE) to test significant differences in the rate of change in outcomes by group longitudinally. We present the collaborative and adaptive strategies for consenting, assenting, and data collection methodology in this community. Achieved response rates are comparable to other similar studies. Results from the two baseline waves indicate that few outcomes significantly varied by randomized intervention assignment. Ten percent of youth reported having had sex at Wave 1, rising to 15% at Wave 2. Among those who had had sex, the majority (>70%) reported using a condom at last sex. The project is well positioned to carry out the longitudinal assessments of the intervention to determine the overall impact of the Circle of Life and the differential impact by pre-intervention patterns of behavior across youth.

Decolonizing strategies for mentoring American Indians and Alaska Natives in HIV and mental health research

American Indian and Alaska Native (AIAN) scholars in the fields of mental health and HIV face formidable barriers to scientific success. These include justifiable mistrust of historically oppressive educational systems, educational disparities, role burdens within academe, the devaluation and marginalization of their research interests, and outright discrimination. Research partners can work to dismantle these barriers by embracing indigenous worldviews, engaging in collaborative research partnerships, building research capacity within universities and tribal communities, changing reward systems, and developing mentoring programs. At the individual level, aspiring AIAN scholars must build coalitions, reject internalized colonial messages, and utilize indigenous ethical frames. The creation of a cadre of AIAN researchers is crucial to improving the health of AIAN peoples.

Identifying heterogeneity among injection drug users: a cluster analysis approach

OBJECTIVES

We used cluster analysis to subdivide a population of injection drug users and identify previously unknown behavioral heterogeneity within that population.

METHODS

We applied cluster analysis techniques to data collected in a cross-sectional survey of injection drug users in Winnipeg, Manitoba. The clustering variables we used were based on receptive syringe sharing, ethnicity, and types of drugs injected.

RESULTS

Seven clusters were identified for both male and female injection drug users. Some relationships previously revealed in our study setting, such as the known relationship between Talwin (pentazocine) and Ritalin (methylphenidate) use, injection in hotels, and hepatitis C virus prevalence, were confirmed through our cluster analysis approach. Also, relationships between drug use and infection risk not previously observed in our study setting were identified, an example being a cluster of female crystal methamphetamine users who exhibited high-risk behaviors but an absence or low prevalence of blood-borne pathogens.

CONCLUSIONS

Cluster analysis was useful in both confirming relationships previously identified and identifying new ones relevant to public health research and interventions.

Sexual health and sexually transmitted infections in the North American Arctic

STI rates reported for the Arctic are much higher than those reported for their southern counterparts.

Our objective was to describe the basic epidemiology of sexually transmitted infections for Arctic and sub-Arctic regions of North America. We summarized published and unpublished rates of chlamydial infection and gonorrhea reported from 2003 through 2006 for Alaska, Canada, and Greenland. In 2006, Alaska reported high rates of chlamydial infection (715 cases/100,000 population) compared with the United States as a whole; northern Canada reported high rates of chlamydial infection (1,693 cases/100,000) and gonorrhea (247 cases/100,000) compared with southern Canada; and Greenland consistently reported the highest rates of chlamydial infection (5,543 cases/100,000) and gonorrhea (1,738 cases/100,000) in the Arctic. Rates were high for both men and women, although the highest incidence of infection was predominantly reported for young women in their early twenties. We propose that community-based participatory research is an appropriate approach to improve sexual health in Arctic communities.
