Prevalence and risk factors of STDs in rural Haiti: implications for policy and programming in resource-poor settings

Prevalence of Neisseria gonorrhoeae and Chlamydia trachomatis in men having sex with men in Port-au-Prince, Haiti: a cross-sectional study

OBJECTIVES

Over the last 15 years, the prevalence of HIV in Haiti has stabilised to around 2.0%. However, key populations remain at higher risk of contracting HIV and other sexually transmitted infections (STIs). The prevalence of HIV is 12.9% among men having sex with men (MSM). There is limited information about the prevalence of other STI in the Haitian population in general and even less among key populations. We assessed the burden of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) and risk factors for infections among MSM in Haiti.

METHODS

A cross-sectional study was conducted. MSM were recruited from seven health facilities in Port-au-Prince. All samples were tested by nucleic acid amplification test, using GeneXpert. A survey was administered to the participants to collect socio-demographic, clinical and risk behaviour data.

RESULTS

A total of 216 MSM were recruited in the study. The prevalence rates of CT and NG were 11.1% and 16.2%, respectively. CT NG co-infections were found in 10/216 (4.6%) of the participants. There were 39 MSM with rectal STI compared with 17 with genital infections. Participants between 18-24 and 30-34 years old were significantly more likely to be infected with NG than those aged 35 years or older (OR: 22.96, 95% CI: 2.79 to 188.5; OR: 15.1, 95% CI: 1.68 to 135.4, respectively). Participants who never attended school or had some primary education were significantly more likely to be infected with NG than those with secondary education or higher (OR: 3.38, 95% CI: 1.26 to 9.07). People tested negative for HIV were significantly more likely to be infected with CT than people living with HIV/AIDS (OR: 3.91, 95% CI: 1.37 to 11.2).

CONCLUSIONS

Periodic risk assessment and testing for STI should be offered in Haiti as part of a comprehensive strategy to improve the sexual health of key populations.

Health Education Training Embedded in a Microfinance Platform Associated with Safer Sexual Behavior in Haitian Women

Sexual health education interventions have generally yielded modest impact, but may be more successful when integrated into programs designed to alleviate poverty and empower women. Between December 2017 and February 2018, we interviewed 304 Haitian female microfinance clients, 75 of whom had received health education training delivered within their regular meetings. Participants reported six key sexual health outcomes. We used log-binomial models to estimate the association between health education training and each outcome, and tested for interaction by age and literacy status. Women with health education training reported more condom use with unfaithful partners [PR (95% CI) 1.78 (1.04, 3.02)], more HIV testing [PR (95% CI) 1.56 (1.28, 1.90)], and fewer STI symptoms [PR (95% CI) 0.37 (0.19, 0.73)], compared to women with no training. Some of the associations were stronger among older women [e.g. HIV testing: PR (95% CI) 2.09 (1.49, 2.82)] and illiterate women [e.g. condom use: PR (95% CI) 3.46 (1.05, 11.38)]. These findings add to the growing body of evidence demonstrating the potential to use microfinance programs as platforms for health education delivery, and provide the first evidence for the association in Haiti.

Best Intentions Are Not Best Practices: Lessons Learned While Conducting Health Research With Trauma-Impacted Female Victims of Nonpartner Sexual Violence in Haiti

Culturally sound health research and culturally relevant interventions are foundational to health promotion and disease prevention around the globe, especially for vulnerable populations in low-and middle-income countries who bear a disproportionate burden of sociodemographic and structural adversities, including gender-based violence and nonpartner sexual violence. There is a limited amount of scientific knowledge regarding the promotion of health equity for Haitian populations and about the challenges of cross-cultural practice and research among them. Using the social dominance and social justice theories as a framework, we discuss challenges encountered and biases discovered while conducting research aimed at finding ways to mitigate biological risks and psychological trauma among female victims of nonpartner sexual violence in Haiti. We highlight personal, professional/ethical, and social and structural barriers. We appeal to researchers who work in Haiti or who desire to work there to collaborate and consolidate their research objectives, to consciously engage in decolonizing their attitudes, and to promote antioppressive discourse about Haiti and its people.

High burden of mental illness and low utilization of care among school-going youth in Central Haiti: A window into the youth mental health treatment gap in a low-income country

BACKGROUND

The mental health treatment gap for youth in low- and middle-income countries (LMICs) is substantial; strategies for redress are urgently needed to mitigate the serious health and social consequences of untreated mental illness in youth.

AIMS

To estimate the burden of major depressive episode (MDE) and posttraumatic stress disorder (PTSD) as well as utilization of care among Haitian youth in order to describe the mental health treatment gap in a LMIC setting.

METHODS

We estimated the point prevalence of MDE, PTSD, and subthreshold variants in a school-based sample of youth ( n = 120, ages 18-22 years) using a modified Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID)-based interview and examined treatment utilization among those receiving one of these diagnoses. We assessed additional psychopathology with self-report measures to examine validity of study diagnostic assignments.

RESULTS

The combined prevalence of full-syndrome or subthreshold MDE or PTSD was high (36.7%). A large majority of affected individuals (88.6%) had accessed no mental health services in the health sector, and 36.4% had accessed no care of any kind in either the health or folk sectors in the past year.

CONCLUSION

Findings demonstrate a high mental health burden among Haiti's youth and that many youth with MDE and PTSD are not accessing mental health care.

Epidemiology of sexually transmitted infections in rural southwestern Haiti: the Grand'Anse Women's Health Study

The study attempts to define socioeconomic, clinical, and laboratory correlates in vaginitis and other sexually transmitted infections in rural southwestern Haiti. A convenience sample of subjects recruited from a rural women's health clinic and attending an established clinic at the Haitian Health Foundation (HHF) clinic was studied. A standardized history and physical examination, including speculum examination, and collection of blood, urine, and vaginal swabs were obtained from the women at the rural clinic. Additional vaginal swab samples only for Nucleic Acid Amplification Test (NAAT) testing were obtained from women at the HHF clinic in Jérémie. Laboratory results from Leon subjects were positive for Gardnerella vaginalis in 41% (41 of 100), Trichomonas vaginalis in 13.5% (14 of 104), Candida sp. in 9% (9 of 100), Mycoplasma genitalium in 6.7% (7 of 104), Chlamydia trachomatis in 1.9% (2 of 104), and Neisseria gonorrhea in 1% (1 of 104) of patients. Human immunodeficiency virus (HIV) antibody tests were negative in 100% (103 of 103) of patients, and syphilis antibody testing was positive for treponemal antibodies in 7.7% (8 of 104) patients. For subjects from the HHF, 19.9% were positive for T. vaginalis, 11.9% were positive for C. trachomatis, 10.1% were positive for M. genitalium, and 4.1% were positive for N. gonorrhea. Infections with G. vaginalis, T. vaginalis, and Candida were the most common. N. gonorrhea, C. trachomatis, Candida sp., T. vaginalis, and M. genitalium infections were associated with younger age (less than 31 years old).

The aetiology of vaginal symptoms in rural Haiti

Vaginal symptoms are a common chief complaint amongst women visiting outpatient clinics in rural Haiti. A systematic sample of 206 consecutive women over age 18 with gynaecological symptoms underwent gynaecologic examination and laboratory testing for chlamydia, gonorrhoea, syphilis, HIV infection, trichomoniasis, candidiasis, and bacterial vaginosis. Among 206 women, 174 (84%) presented with vaginal discharge, 165 (80%) with vaginal itching, 123 (60%) with vaginal pain or dysuria, and 18 (9%) with non-traumatic vaginal sores or boils. Laboratory results were positive forChlamydia trachomatisin 5.4% (11/203), syphilis in 3.5% (7/202), HIV in 1.0% (2/200), andNeisseria gonorrhoeaein 1.0% (2/203). Among those that had microscopy, hyphae suggestive of candidiasis were visualized in 2.2% (1/45) and no cases of trichomoniasis were diagnosed 0% (0/45). Bacterial vaginosis was diagnosed in 28.3% (13/46). The prevalence of chlamydia was 4.9 (95% CI: 1.3-17.7) times greater among those 25 years of age and under (10.8%) than those older (2.3%). Chlamydia and bacterial vaginosis were the most common sexually transmitted infection and vaginal condition, respectively, in this study of rural Haitian adult women. The higher risk of chlamydia in younger women suggests education and screening programmes in young women should be considered.

Epidemiologic profile of patients seen in primary care clinics in an urban and a rural setting in Haiti, 2010-11

BACKGROUND

This study examined the demographic and epidemiological differences between patient populations presenting to a rural and an urban clinic in Haiti.

METHODS

A primary health clinic was established in urban Leogane, and a once-weekly clinic was established in Magandou, a rural village. Patient data were recorded for all individuals presenting to each clinic.

RESULTS

Over 7 months, 6632 patients (median age 25) were seen in the urban clinic, and 567 (median age 47) in the rural clinic. There was a female majority at both sites. Hypertension was diagnosed in 41.9% (238/567) of the rural population over 40 years of age, while 29.5% (1956/6632) of patients in the urban setting had the same diagnosis (p<0.001). Among women of reproductive age, 20.4% (1353/6632) were diagnosed with STDs in the urban setting versus 8.6% (49/567) at the rural clinic (p=0.004). Eighty-eight patients at the urban clinic had a vector-borne disease, while none were diagnosed among the rural population.

CONCLUSIONS

Screening and treatment of hypertension in Haiti must address the wide rural prevalence. STDs are a major urban health issue requiring treatment for both patients and their partners. Vector-borne disease was unseen in the rural clinic, despite an altitude insufficient to prevent mosquito-borne illness.

"I am proud of myself, just the way I am" (Mwen fyé de tét mwen, jan mwen ye ya): a qualitative study among young Haitian women seeking care for sexually transmitted infections (STIs) in Haiti

Haitian women are twice as likely as men to have HIV/AIDs. Factors underlying the feminization of HIV are complex. Self-esteem is an important correlate of sexual behavior. However, its meaning and impact on health behaviors may be influenced by cultural factors. This qualitative study took place in Haiti 4 months after the 2010 earthquake and examines the meaning of self-esteem among young Haitian women seeking treatment for a recurrent sexually transmitted infection (STI). The meaning of self-esteem was derived from a sense of gratitude and was rooted in their ability to provide for family. This may have led to behaviors such as not using condoms or having sex with partners in concurrent relationships. This article highlights the resilience and resourcefulness of Haitian women, provides insight into how women with apparent positive self-images were led to make choices that placed them at high risk for contracting HIV, and concludes with recommendations for future interventions.

Prevalence and correlates of HIV testing among Caribbean youth

Little is known about the HIV testing behaviours among Caribbean youth. The purpose of this study was to determine the prevalence of and the factors associated with HIV testing in Caribbean youth. Data were used from population-based surveys in three Caribbean countries: Guyana, Haiti and the Dominican Republic. Chi-square tests and multiple logistic regression models were fitted to examine the associations between independent correlates and ever being tested of HIV. The proportion of youth reporting HIV testing ranged from 17% in Haiti to 48% in the Dominican Republic. Across all countries increased odds of ever being tested for HIV was associated with ever being married, having five or more lifetime partners, and knowing someone who was living with or had died from HIV. Male gender and rural residence were correlated with decreased odds of HIV testing. Low levels of HIV testing were observed among sexually experienced youth in three Caribbean countries. Men, younger and never married youth were less likely to be have been tested for HIV. Outreach and public health messages targeting these youth should be implemented. Programmes that assist youth in accurately assessing their risk behaviours are also required to improve HIV testing.

The role of a microfinance program on HIV risk behavior among Haitian women

Microfinance loans targeted at vulnerable female populations have the potential to foster female economic independence, possibly leading to the negotiation of safer sexual practices and reduced HIV risk. This study assessed the relationship between experience with microfinance loans and HIV risk behavior among 192 female clients of the Haitian microfinance organization Fonkoze. Clients with longer microfinance experience were generally found to have lower indicators of HIV risk behavior and higher indicators of relationship power compared to those with shorter experience. In particular, those with longer memberships were 72% less likely to report partner infidelity, were 3.95 times more likely to use condoms with an unfaithful partner, and had higher average general power index scores compared to those with shorter experience. This study provides evidence that long-term exposure to microfinance is associated with reduced HIV risk behavior in Haitian women and that this reduction may be partly regulated by influencing relationship power. These results suggest the need to further explore the use of microfinance as a tool to prevent the spread of HIV.

Economic risk factors for HIV infection among women in rural Haiti: implications for HIV prevention policies and programs in resource-poor settings

AIMS

The goals of this study were to (1) estimate the prevalence of HIV infection among women accessing services at a women's health center in rural Haiti and (2) to identify economic risk factors for HIV infection in this population.

METHODS

Women who accessed healthcare services at this center between June 1999 and December 2002 were recruited to participate. The analysis was based on data from a case-control study of sexually transmitted diseases (STDs) in rural Haiti. HIV prevalence in the study population was 4%.

RESULTS

In multivariate analyses, partner occupation was associated with HIV infection in women, with mechanic (OR 9.0, 95% CI 1.8-45) and market vendor (OR 4.2, 95% CI 1.6-11) reflecting the strongest partner occupational risk factors. Partner's occupation as a farmer reduced the risk of infection in women by 60% (95% CI 0.14-1.1). Factors indicating low socioeconomic status (SES), such as food insecurity (OR 2.0, 95% CI 0.75-5.6) and using charcoal for cooking (OR 1.7, 95% CI 0.72-3.8) suggested an association with HIV infection.

CONCLUSIONS

Given pervasive gender inequality in Haiti, women's economic security often relies on their partners' income earning activities. Our findings show that although factors reflecting poverty are associated with HIV-positive status, stronger associations are observed for women whose partners indicated a more secure occupation (e.g., mechanic or market vendor). Policies and programs that expand access to education and economic opportunities for women and girls may have long-term implications for HIV prevention in Haiti and other resource-poor settings.

The prevalence of other sexually transmitted infections in confirmed HIV cases at a referral clinic in Jamaica

Jamaica has the second highest number of acquired immunodeficiency syndrome (AIDS) cases and deaths in the Caribbean and a significant number of human immunodeficiency virus (HIV) infected individuals have a concomitant sexually transmitted infection (STI). The study determined the prevalence of non-ulcerative and ulcerative STIs and their association with sexual risky behaviour in a sample of HIV seropositive men and women. This study was conducted at the Comprehensive Health Centre in Jamaica, a sexually transmitted infection referral centre. The sample comprised 138 men and 132 women age 15—49 years, of average 29.5 years. The study was retrospective, from 2000 to 2002, and sample collection was randomized. The sexual behaviours of the subjects were assessed from the case records. In the 270 HIV diagnosed cases examined, the prevalence of STIs was 51.1% in men and 48.9% in women, with 85.4% having one or more STIs with an average of four STIs per patient. There was a total occurrence of 744 STIs with non-gonococcal urethritis (19.4%), gonorrhoea (17.2%), candidiasis (13.4%), trichomonas (12.4%), genital ulcer (10.4%) and syphilis (7.3%) the most common in HIV infected men and women. The presence of STI was associated with continued practice of risky sexual behaviour. The age group most implicated was the 30—34 year old, and 73.1% of the HIV infected patients had multiple sexual partners with only 16.4% reporting frequent condom use. The study demonstrates that there is a high prevalence of non-ulcerative and to a lesser extent ulcerative STIs in HIV infected patients in Jamaica. There are significant associations between STIs and continued high risk sexual practices in HIV infected men and women. The findings support the need for implementation of effective diagnosis and treatment strategies coupled with education about safe-sex practices in HIV prevention and STI control programmes.

Community health workers as a cornerstone for integrating HIV and primary healthcare

Haiti is the poorest and most heavily HIV-burdened country in the Western hemisphere, with even less health infrastructure than many countries of sub-Saharan Africa. Since the early 1980s the HIV epidemic has affected the poorest communities in Haiti, who lack access to even basic healthcare. Large-scale HIV treatment requires that basic healthcare services be built and scaled up simultaneously with HIV-prevention and -care programmes. Such improvement in access to general healthcare will require substantial investments in health infrastructure, service delivery and human development. This study describes the contribution of the non-governmental organization, Zanmi Lasante (ZL) to the HIV prevention and treatment scale-up and to the ongoing efforts to improve primary healthcare (PHC) services in the public health system in Haiti. The model depends on community health workers (CHWs) who supervise antiretroviral therapy (ART) and provide community outreach, including active case finding and outreach to marginalized populations. Zanmi Lasante has recruited, trained and financed a large cadre of CHWs to provide such linkages between communities and health centres in rural Haiti. The study analysed key components of their work--their self-perception, their role in enhancing community uptake of services and their role in targeting vulnerable groups. We found that most patients at risk were properly identified at a community level. The CHWs are facilitating the uptake of PHC services, including by the most vulnerable households. The general training of CHWs has created a positive self-definition in these cadres of their medical, patient support and health service roles; although with some variability across different groups. The results of this study will be used to emphasize, standardized and strengthen the biosocial training of CHWs.

Identification of chlamydia and gonorrhoea among women in rural Haiti: maximising access to treatment in a resource poor setting

OBJECTIVE

To develop a risk assessment algorithm that will increase the identification and treatment of women with cervical infection in rural Haiti.

METHODS

Study participants were randomly selected from new patients who accessed services at a women's health clinic in rural Haiti between June 1999 and December 2002. This case-control study included women who tested positive for chlamydia and/or gonorrhoea based on the Gen-Probe PACE 2 laboratory test as cases. Controls were women who tested negative for both of these infections.

RESULTS

Women from this area of rural Haiti had a limited level of education and lived in impoverished housing conditions. The sensitivity estimates of Haitian Ministry of Health and WHO algorithms for detecting chlamydia and/or gonorrhoea were generally low (ranging from 16.1% to 68.1%) in this population. Risk scores based on logistic regression models of local risk factors for chlamydia and gonorrhoea were developed and sensitivity estimates were higher for algorithms based on these risk scores (up to 98.8%); however, specificity was compromised.

CONCLUSIONS

A risk assessment algorithm to identify women with chlamydia and/or gonorrhoea is more sensitive and less specific than the syndromic management approach advocated by WHO and adapted by the Haitian Ministry of Health. Using a risk assessment tool with high sensitivity based on local risk factors of cervical infection will maximise access to care, improve outcomes, and decrease morbidity in women who have cervical infection in rural Haiti.

The influence of power on HIV risk among pregnant women in rural Haiti

Given that condom use is not directly under a woman's control, the sexual division of power may play an important role in sexual behavior among pregnant women. We assessed the influence of factors related to the theory of gender and power (e.g., relationship power, abuse history, and sexual communication) on sexual behavior (e.g., two or more partners in the year prior to pregnancy, condom use, condom-use intentions, and STI diagnosis) among 196 pregnant women recruited from five community dispensaries in rural Haiti. Results showed that gender and power factors significantly related to sexual behavior. Gender and power factors were most significant for condom use and intention to use condoms, accounting for 18 and 25% of the variance above and beyond HIV knowledge and demographic covariates, respectively. These results suggest the need to create prevention interventions that restore power imbalances, provide support for women suffering abuse, and strengthen communication skills.

Behavior change and health-related interventions for heterosexual risk reduction among drug users

Prevention of heterosexual transmission of HIV between and from drug users is important for controlling the local and global HIV heterosexual epidemic. Sex risk reduction interventions and health-related interventions are important for reducing the sex risk behaviors of drug users. Sex risk reduction interventions address individual-level, peer-level, and structural-level determinants of risk reduction. Health-related interventions include HIV counseling and testing, prevention and treatment of sexually transmitted diseases, and delivery of highly active antiretroviral therapy. It is important to adapt effective interventions implemented in resource-rich countries to the realities of the resource-constrained settings and to address relevant contextual factors.

Factors associated with forced sex among women accessing health services in rural Haiti: implications for the prevention of HIV infection and other sexually transmitted diseases

The goals of the current study were to: (1) estimate the prevalence of forced sex among women accessing services at a women's health clinic in rural Haiti; and (2) examine factors associated with forced sex in this population. Based on data from a case-control study of risk factors for sexually transmitted diseases (STDs), a cross-sectional analysis to examine factors associated with forced sex was performed. A number of factors related to gender inequality/socioeconomic vulnerability placed women in rural Haiti at higher risk of forced sex. The strongest factors associated with forced sex in multivariate analyses were: age, length of time in a relationship, occupation of the woman's partner, STD-related symptoms, and factors demonstrating economic vulnerability. The findings suggest that prevention efforts must go beyond provision of information and education to the pursuit of broader initiatives at both local and national levels. At the community level, policy-makers should consider advancing economic opportunities for women who are vulnerable to forced sex. Improving access to community-based income-generating activities may begin to address this problem. However, the viability of these local projects depends largely upon Haiti's 'macro-economic' situation. In order to ensure the success of local initiatives, external humanitarian and development assistance to Haiti should be supported. By broadening the definition of "prevention" interventions, we may begin to address the systemic problems that contribute to the occurrence of forced sex and the increasing incidence of HIV infection throughout the world, such as gender inequality and economic vulnerability. Taking into account factors influencing risk at the local level as well as the macro-level will potentially improve our capacity to reduce the risk of forced sex and the spread of STDs, including HIV infection, for millions of women living in poverty worldwide.

Reducing health disparities through culturally sensitive treatment for HIV+ adults in Haiti

There is a critical need to deliver empirically validated interventions to underserved populations. Haiti, the country most heavily affected by the AIDS epidemic in the Caribbean, accounts for approximately 50% of all cases in the region. Poverty, disparities in access to healthcare, and socio-political instability are among the reasons why the country has been ravaged by the disease. Ongoing projects in Haiti have shown that integrated prevention and care in resource poor settings are feasible and can be successful, as evidenced by a 50% drop in incidence among pregnant women since 1993. The AIDS prevention program has embarked on a comprehensive effort to culturally adapt a cognitive-behavioral stress management program for Haitian HIV+ individuals. The purpose of the program is to improve adherence to antiretroviral medication, reduce transmission to uninfected partners, and improve coping. This comprehensive approach is necessary to ensure the validity of the cross-cultural adaptation of this intervention.

Scaling-up HIV treatment programmes in resource-limited settings: the rural Haiti experience

OBJECTIVE

To scale-up a successful HIV/AIDS treatment project and provide comprehensive care to an entire Département du Centre (population 550 000) in rural Haiti, thereby demonstrating that community-based treatment of HIV is feasible and highly effective in resource-limited settings, and serving as a successful model for others to replicate.

PARTICIPANTS

In the Département du Centre of rural Haiti comprehensive HIV and tuberculosis treatment is provided free of charge to anyone who presents for care. All those who meet clinical enrolment criteria are treated with highly active antiretroviral therapy (HAART).

INTERVENTION

HAART was provided in the context of a comprehensive programme of HIV, tuberculosis (TB), sexually transmitted disease (STD) of the project, treatment and prevention, and women's health services at four sites in the first year. At each site, the medical facility was renovated, additional staff were hired as needed, and a network of accompagnateurs (community health workers) was established throughout the surrounding villages to serve as a link with the community, and to provide directly observed treatment (DOT).

RESULTS

In the first year of programme scale-up, over 8000 patients were followed for HIV, and over 1050 were treated with DOT HAART. Adherence to HAART was very high, and clinical outcomes were excellent: all patients responded with weight gain and improved functional capacity, and fewer than 5% required medication changes due to side effects. Viral load was tested among a subset of patients showing that 86% had undetectable viral loads.

CONCLUSION

Community-based care of AIDS has been highly effective in rural Haiti. With more international financial support for HIV/AIDS treatment in resource-limited settings, there should be no barriers to access to life-saving HAART for those who need it most.

From Directly Observed Therapy to Accompagnateurs: Enhancing AIDS Treatment Outcomes in Haiti and in Boston

Like tuberculosis, human immunodeficiency virus (HIV) disease is associated with poverty and social inequalities, conditions that hamper the delivery of care. Like tuberculosis, treatment of HIV infection requires multidrug regimens, and the causative agent acquires drug resistance, which can be transmitted to others. A pilot project in rural Haiti introduced DOT-HAART (directly observed therapy with highly active antiretroviral therapy) for the care of patients with advanced acquired immune deficiency syndrome. A similar DOT-HAART effort was launched in Boston for patients with drug-resistant HIV disease who had experienced failure of unsupervised therapy. In both settings, community health promoters or accompagnateurs provide more than DOT: they offer psychosocial support and link patients to clinical staff and available resources. DOT-HAART in these 2 settings presents both challenges and opportunities. These models of care can be applied to other poverty-stricken populations in resource-poor settings.
