Background: Intimate partner violence (IPV) is prevalent in low and middle-income countries, such as Haiti. However, there is little research on its association with mental health problems such as psychological distress and depression. Although there is evidence that men may experience IPV, few studies have investigated mental health difficulties among Haitian men and women. The present study aims to 1) assess the prevalence of depressive symptoms and psychological distress in this population and 2) examine the association between IPV, psychological distress, and depression while considering potential risk and protective factors., Method: A representative sample of 3,586 adolescents and young adults aged 15 to 24 living in Haiti was recruited. Structural equation modeling was used to examine the association between IPV, depressive symptoms, and psychological distress., Results: Almost half of the sample reported depressive symptoms and psychological distress, with high rates among both genders. IPV was found to be an independent predictor of both depressive symptoms and psychological distress after accounting for risk and protective factors., Limitation: This study is the first step in understanding the interplay between IPV victimization, risk and protective factors, and psychological difficulties in this population. However, because of the cross-sectional design, causality should not be inferred. Furthermore, this study did not measure community violence, which could have affected participants' mental health., Conclusion: This study highlights the importance of considering the occurrence of IPV victimization when evaluating depression and psychological distress among adolescents and young adults., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Sexual assault victims are at major risk of being infected by sexually transmitted infections (STI). This article aims to examine and compare the prevalence of eight STIs (e.g., chlamydia, gonorrhea, hepatitis B, HIV/AIDS, human papillomavirus) among victims and non-victims of sexual abuse. A national cross-sectional study was conducted in Haiti, using a multistage sampling frame, stratified by geographical department, urban or rural setting, gender, and age groups (15-19 and 20-24 years). The final sample included 3586 household participants (47.6% female). A weighted sample of 3945 individuals was obtained and used in the following analyses. Overall, 21.75% (95% CI 19.91-23.59) of participants reported having been diagnosed with at least one STI in their lifetime, with a higher prevalence among men (25.70%; 95% CI 22.89-28.52), compared to women (18.11%; 95% CI 15.73-20.49), χ 2  = 16.43; p < 0.001). Sexual abuse victims were more likely to report STIs (31.27%; 95% CI 29.21-33.34), compared to non-victims (18.40%; 95% CI 16.68-20.13), χ 2  = 27.89; p < .001. Sexual abuse was associated to an increased risk of contracting at least one STI (OR = 1.74; 95% CI 1.35, 2.24). The results demonstrate that sexual abuse is associated with a general increase of reporting STIs. They indicate the need for national sexual abuse prevention programs at early ages. These programs should be implemented in schools and churches, focusing on the role of families in sexuality education. Finally, programs must be developed to eradicate community violence-especially in the cities-as increased political and social violence has always been associated with increased sexual abuse in Haiti., (© 2024.

Hypertension is a leading contributor to mortality in low-middle income countries including Haiti, yet only 13% achieve blood pressure (BP) control. We evaluated the effectiveness of a community-based hypertension management program delivered by community health workers (CHWs) and physicians among 100 adults with uncontrolled hypertension from the Haiti Cardiovascular Disease Cohort. The 12-month intervention included: community follow-up visits with CHWs (1 month if BP uncontrolled ≥140/90, 3 months otherwise) for BP measurement, lifestyle counseling, medication delivery, and dose adjustments. Primary outcome was mean change in systolic BP from enrollment to 12 months. Secondary outcomes were mean change in diastolic BP, BP control, acceptability, feasibility, and adverse events. We compared outcomes to 100 age, sex, and baseline BP matched controls with standard of care: clinic follow-up visits with physicians every 3 months. We also conducted qualitative interviews with participants and providers. Among 200 adults, median age was 59 years, 59% were female. Baseline mean BP was 154/89 mmHg intervention versus 153/88 mmHg control. At 12 months, the difference in SBP change between groups was -12.8 mmHg (95%CI -6.9, -18.7) and for DBP -7.1 mmHg (95%CI -3.3, -11.0). BP control increased from 0% to 58.1% in intervention, and 28.4% in control group. Four participants reported mild adverse events. In mixed methods analysis, we found community-based delivery addressed multiple participant barriers to care, and task-shifting with strong teamwork enhanced medication adherence. Community-based hypertension management using task-shifting with CHWs and community-based care was acceptable, and effective in reducing SBP, DBP, and increasing BP control., (© 2024 The Author(s).

Objective: The effects of sanitation and hygiene interventions on the gut microbiome and enteric pathogen burden are not well understood. We measured the association between free chlorine residue (FCR) levels in drinking water, microbiome composition, and stool enteric pathogens in infants and young children in Haiti., Methods: FCR levels were measured in household drinking water and enteric pathogen burden was evaluated using multiplex RT-PCR of stool among 131 children from one month to five years of age living in Mirebalais, Haiti. Microbiome profiling was performed using metagenomic sequencing., Results: Most individuals lived in households with undetectable FCR measured in the drinking water (112/131, 86%). Detection of enteric pathogen DNA in stool was common and did not correlate with household water FCR. The infant microbiome in households with detectable FCR demonstrated reduced richness (fewer total number of species, P = 0.04 Kruskall-Wallis test) and less diversity by Inverse Simpson measures (P = 0.05) than households with undetectable FCR. Infants in households with a detectable FCR were more likely to have abundant Bifidobacterium. Using in vitro susceptibility testing, we found that some Bifidobacterium species were resistant to chlorine., Conclusions: FCR in household drinking water did not correlate with enteric pathogen burden in our study., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Tuberculosis is a leading cause of death worldwide, and food insecurity is known to negatively influence health outcomes through multiple pathways. Few studies have interrogated the relationship between food insecurity and tuberculosis outcomes, particularly independent of nutrition., Methods: We conducted a prospective cohort study of adults initiating first-line treatment for clinically suspected or microbiologically confirmed drug-sensitive tuberculosis at a rural referral center in Haiti. We administered a baseline questionnaire, collected clinical data, and analyzed laboratory samples. We used logistic regression models to estimate the relationship between household food insecurity (Household Hunger Scale) and treatment failure or death. We accounted for exclusion of patients lost to follow-up using inverse probability of censoring weighting and adjusted for measured confounders and nutritional status using inverse probability of treatment weighting., Results: We enrolled 257 participants (37% female) between May 2020 and March 2023 with a median age (interquartile range) of 35 (25-45) years. Of these, 105 (41%) had no hunger in the household, 104 (40%) had moderate hunger in the household, and 48 (19%) had severe hunger in the household. Eleven participants (4%) died, and 6 (3%) had treatment failure. After adjustment, food insecurity was significantly associated with subsequent treatment failure or death (odds ratio 5.78 [95% confidence interval, 1.20-27.8]; P = .03)., Conclusions: Household food insecurity at tuberculosis treatment initiation was significantly associated with death or treatment failure after accounting for loss to follow-up, measured confounders, and nutritional status. In addition to the known importance of undernutrition, our findings indicate that food insecurity independently affects tuberculosis treatment outcomes in Haiti., Competing Interests: Potential conflicts of interest .

The Ministry of Public Health and Population in Haiti is committed to malaria elimination. In 2017, we used novel methods to conduct a census, monitor progress, and return to sampled households (HH) before a cross-sectional survey in La Chapelle and Verrettes communes in Artibonite department ("the 2017 Artibonite HH census"). Geospatial PDFs with digitized structures and basemaps were loaded onto tablets. Enumerators captured GPS coordinates and details of each HH and points of interest. The census used 1 km2 enumeration areas (EAs) to draw a representative sample. Three remote sampling frames were compared with the 2017 Artibonite HH census. First, 2003 census EAs with 2012 population estimates from the Haitian Institute of Statistics and Informatics were standardized to the study EAs. The second sampling frame used the 2016 LandScanTM population estimates and study EAs. The third sampling frame used structures ≥3 m2 manually digitized using Maxar satellite images. In each study EA, 70% of structures were estimated to be inhabited with 4.5 persons/HH. The census identified 33,060 inhabited HHs with an estimated population of 121,593 and 6,126 points of interest. Using daily coverage maps and including digitized structures were novel methods that improved the census quality. Manual digitization was closest to the census sampling frame results with 30,514 digitized structures in the study area. The LandScanTM method performed better in urban areas; however, it produced the highest number of HHs to sample. If a census is not possible, when feasible, remotely digitizing structures and estimating occupancy may provide a close estimate.

Although the high prevalence of intimate partner violence (IPV) in Haiti is well-documented, its association with post-traumatic stress disorder (PTSD) symptoms among adolescents and young adults remains unexplored. Using a representative sample of adolescents and young adults from rural and urban areas across the 10 geographical regions of Haiti, this study investigates the association between IPV and PTSD symptoms. It explores the role of social support, emotion regulation, other traumatic events, and sociodemographic factors. The sample consisted of 3,586 participants, of whom 43.21 % (1,538) reported being in a dating relationship in the past year (56.04 % women). Overall, 25.53 % of the participants were categorized as having probable PTSD. Results showed that participants who experienced at least one episode of IPV victimization presented a higher prevalence of PTSD (32.28 %) compared to those who did not have any experience (16.29 %), χ 2 (1) = 44.83, p < .001. The logistic regression model showed that emotional IPV, sexual IPV, traumatic life events, emotional dysregulation, and social support were associated with PTSD symptoms. This study highlights a strong association between IPV and PTSD symptoms, as well as factors that can contribute to the development and implementation of prevention and intervention programs among adolescents and young adults in Haiti., Competing Interests: Declaration of competing interest No conflict of interest for any author., (Copyright © 2024 The Authors.

Importance: Higher social vulnerability is associated with premature cardiovascular disease (CVD) and mortality but is understudied in low-income countries that have both the highest magnitude of social vulnerability and a growing CVD epidemic., Objective: To evaluate the association between social vulnerability and hypertension, CVD, and CVD subtypes in Haiti as a model for similar low-income countries., Design, Setting, and Participants: This population-based cohort study used enrollment data from adults participating in the Haiti Cardiovascular Disease Cohort Study. Recruitment occurred via multistage random sampling throughout slum and urban neighborhoods in Port-au-Prince, Haiti, from March 2019 to August 2021. Data were analyzed from May 2022 to December 2023., Exposures: A modified Haitian Social Vulnerability Index (SVI-H) was created following the US Centers for Disease Control and Prevention Social Vulnerability Index method. Twelve variables across the domains of socioeconomic status, household characteristics, and social and community context were included. The SVI-H was calculated for each study neighborhood block and then stratified into SVI-H quartiles (quartile 1 was the least vulnerable; quartile 4, the most vulnerable)., Main Outcomes and Measures: Prevalent hypertension and total CVD, defined as heart failure (HF), stroke, transient ischemic attack (TIA), angina, or myocardial infarction (MI). Age-adjusted Poisson regression analysis yielded prevalence ratios (PRs) comparing the prevalence of hypertension, total CVD, and CVD subtypes across SVI-H quartiles., Results: Among 2925 adults (1704 [58.3%] female; mean [SD] age, 41.9 [15.9] years), the prevalence of hypertension was 32.8% (95% CI, 31.1%-34.5%) and the prevalence of CVD was 14.7% (95% CI, 13.5%-16.0%). Hypertension prevalence ranged from 26.2% (95% CI, 23.1%-29.3%) to 38.4% (95% CI, 34.8%-42.0%) between quartiles 1 and 4, while CVD prevalence ranged from 11.1% (95% CI, 8.8%-13.3%) to 19.7% (95% CI, 16.8%-22.6%). SVI-H quartile 4 vs 1 was associated with a greater prevalence of hypertension (PR, 1.17; 95% CI, 1.02-1.34) and CVD (PR, 1.48; 95% CI, 1.16-1.89). Among CVD subtypes, SVI-H was significantly associated with HF (PR, 1.64; 95% CI, 1.23-2.18) but not with combined stroke and TIA or combined angina and MI., Conclusions and Relevance: In urban Haiti, individuals living in neighborhoods with the highest social vulnerability had greater prevalence of hypertension and HF. Understanding CVD disparities in low-income countries is essential for targeting prevention and treatment interventions toward populations at highest risk globally.

Refugees usually face a disproportionate burden of infectious diseases. Recently, Brazil has experienced an influx of refugees which demands the need for scaling up public health efforts to address the challenges. The research sought to study the burden and risk factors associated with infectious diseases among refugees received in the city of Porto Alegre. This was a cross-sectional study of 261 newly arrived refugees. The study sample was predominantly composed of Venezuelans (50.6%) and Haitians (44%), male (146: 56.7%), single (30.7%), with an average age of 33.38 (± 7.30) years. The average schooling was 10.42 (± 2.09) years. Diseases with the highest prevalence were influenza, whooping cough, diphtheria, and tuberculosis. There was significant association between the country of origin and presence of symptoms for infectious and contagious diseases, which warrants targeted interventions for reducing the incidence of these diseases among refugees in Brazil., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Introduction: The J9 Plus (J9) maternal-child accompaniment program is based on four pillars: group antenatal care (GANC), group pediatric care, psychosocial support, and community-based care. We aimed to evaluate the impact of the J9 model of care on perinatal outcomes., Methodology: We conducted a convergent mixed methods study of maternal-newborn dyads born in 2019 at Hôpital Universitaire de Mirebalais. Quantitative data was collected retrospectively to compare dyads receiving J9 care to usual care. A secondary analysis of qualitative data described patient perspectives of J9 care., Results: Antenatal care attendance was significantly higher among women in J9 (n = 524) compared to usual care (n = 523), with 490(93%) and 189(36%) having >4 visits, respectively; p <0.001, as was post-partum visit attendance [271(52%) compared to 84(16%), p<0.001] and use of post-partum family planning methods [98(19%) compared to 47(9%), p = 0.003]. Incidence of pre-eclampsia with severe features was significantly lower in the J9 group [44(9%)] compared to the usual care group [73(14%)], p <0.001. Maternal and neonatal mortality and low birth weight did not differ across groups. Cesarean delivery [103(20%) and 82(16%), p<0.001] and preterm birth [118 (24%)] and 80 (17%), p <0.001] were higher in the J9 group compared to usual care, respectively. In the qualitative analysis, ease of access to high-quality care, meaningful social support, and maternal empowerment through education were identified as key contributors to these outcomes., Conclusion: Compared to usual care, the J9 Plus maternal-child accompaniment model of care is associated with increased engagement in antenatal and postpartum care, increased utilization of post-partum family planning, and lower incidence of pre-eclampsia with severe features, which remains a leading cause of maternal mortality in Haiti. The J9 accompaniment approach to care is an empowering model that has the potential to be replicated in similar settings to improve quality of care and outcomes globally., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Casella Jean-Baptiste et al.

Background: In Haiti, reported incidence and mortality rates for COVID-19 were lower than expected. We aimed to analyze factors at communal and individual level that might lead to an underestimation of the true burden of the COVID-19 epidemic in Haiti during its first two years., Methods: We analyzed national COVID-19 surveillance data from March 2020 to December 2021, to describe the epidemic using cluster detection, time series, and cartographic approach. We performed multivariate Quasi-Poisson regression models to determine socioeconomic factors associated with incidence and mortality. We performed a mixed-effect logistic regression model to determine individual factors associated with the infection., Results: Among the 140 communes of Haiti, 57 (40.7%) had a COVID-19 screening center, and the incidence was six times higher in these than in those without. Only 22 (15.7%) communes had a COVID-19 care center, and the mortality was five times higher in these than in those without. All the richest communes had a COVID-19 screening center while only 30.8% of the poorest had one. And 75% of the richest communes had a COVID-19 care center while only 15.4% of the poorest had one. Having more than three healthcare workers per 1000 population in the commune was positively associated with the incidence (SIR: 3.31; IC95%: 2.50, 3.93) and the mortality (SMR: 2.73; IC95%: 2.03, 3.66). At the individual level, male gender (adjusted OR: 1.11; IC95%: 1.01, 1.22), age with a progressive increase of the risk compared to youngers, and having Haitian nationality only (adjusted OR:2.07; IC95%: 1.53, 2.82) were associated with the infection., Conclusions: This study highlights the weakness of SARS-CoV-2 screening and care system in Haiti, particularly in the poorest communes, suggesting that the number of COVID-19 cases and deaths were probably greatly underestimated., (© 2024.

Haiti is endemic for lymphatic filariasis (LF) and malaria, two mosquito-transmitted parasitic diseases targeted for elimination. The World Health Organization recommends a transmission assessment survey (TAS-1) to determine if LF prevalence is significantly beneath putative transmission thresholds (<2% antigen prevalence in Haiti, where Culex is the primary vector for Wuchereria bancrofti) to stop mass drug administration (MDA). Repeated TASs (TAS-2 and TAS-3) are recommended at 2-3-year intervals during post-treatment surveillance. From 2017 to 2022, The Carter Center assisted the Haitian Ministry of Public Health and Population in conducting 15 TASs in 11 evaluation units (EUs) encompassing 54 of the country's 146 districts. Children 6-7 years old were assessed for circulating filarial antigen (CFA) by Filariasis Test Strip: n = 5,239 in TAS-1; n = 11,866 in TAS-2; and n = 1,842 in TAS-3, of whom eight (0.15%), 20 (0.17%), and eight (0.43%) tested positive, respectively. The number of positive results in children was less than the threshold in each EU. When available, participants (n = 16,663) were also tested for malaria by rapid diagnostic test, with 31 (0.19%) children testing positive for Plasmodium falciparum. Integrated TASs provided an efficient means to collect epidemiological data for LF and malaria in Haiti. Results indicated thresholds for stopping and maintaining the halt of MDA for LF have been achieved in all EUs, with the halt of MDA for 571,358 people in four districts and the first TAS-3 surveys conducted in Haiti. Investigations are needed to assess the potential of ongoing LF transmission, especially in areas where CFA-positive samples were detected in TAS-3.

The 2022 outbreak of mpox disproportionately impacted men who have sex with men and people living with HIV. As such, HIV organizations were uniquely situated to reach populations affected by mpox. However, the extent to which these organizations pivoted to address mpox, and what form mpox messaging took, is unknown. We conducted a rapid environmental scan of 29 HIV or sexual health organizations to assess the frequency and content of mpox messaging in August 2022, the peak of the mpox outbreak in Miami, FL. Approximately half of the organizations provided mpox messaging, most of which was accurate. Only 5% of the messages were in Spanish and 4% in Spanish and Haitian Creole. Our findings suggest HIV organizations' pivot to mpox messaging may have been delayed overall and in reaching Spanish- and Haitian Creole-speaking communities. Results could inform modifications to mpox messaging campaigns and future outbreaks that disproportionately affect minoritized communities., (© 2023.

Public health decisions must be made about when and how to implement interventions to control an infectious disease epidemic. These decisions should be informed by data on the epidemic as well as current understanding about the transmission dynamics. Such decisions can be posed as statistical questions about scientifically motivated dynamic models. Thus, we encounter the methodological task of building credible, data-informed decisions based on stochastic, partially observed, nonlinear dynamic models. This necessitates addressing the tradeoff between biological fidelity and model simplicity, and the reality of misspecification for models at all levels of complexity. We assess current methodological approaches to these issues via a case study of the 2010-2019 cholera epidemic in Haiti. We consider three dynamic models developed by expert teams to advise on vaccination policies. We evaluate previous methods used for fitting these models, and we demonstrate modified data analysis strategies leading to improved statistical fit. Specifically, we present approaches for diagnosing model misspecification and the consequent development of improved models. Additionally, we demonstrate the utility of recent advances in likelihood maximization for high-dimensional nonlinear dynamic models, enabling likelihood-based inference for spatiotemporal incidence data using this class of models. Our workflow is reproducible and extendable, facilitating future investigations of this disease system., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Wheeler et al.

Background: The Global Programme to Eliminate Lymphatic Filariasis (GPELF) aims to reduce and maintain infection levels through mass drug administration (MDA), but there is evidence of ongoing transmission after MDA in areas where Culex mosquitoes are the main transmission vector, suggesting that a more stringent criterion is required for MDA decision making in these settings., Methods: We use a transmission model to investigate how a lower prevalence threshold (<1% antigenemia [Ag] prevalence compared with <2% Ag prevalence) for MDA decision making would affect the probability of local elimination, health outcomes, the number of MDA rounds, including restarts, and program costs associated with MDA and surveys across different scenarios. To determine the cost-effectiveness of switching to a lower threshold, we simulated 65% and 80% MDA coverage of the total population for different willingness to pay per disability-adjusted life-year averted for India ($446.07), Tanzania ($389.83), and Haiti ($219.84)., Results: Our results suggest that with a lower Ag threshold, there is a small proportion of simulations where extra rounds are required to reach the target, but this also reduces the need to restart MDA later in the program. For 80% coverage, the lower threshold is cost-effective across all baseline prevalences for India, Tanzania, and Haiti. For 65% MDA coverage, the lower threshold is not cost-effective due to additional MDA rounds, although it increases the probability of local elimination. Valuing the benefits of elimination to align with the GPELF goals, we find that a willingness to pay per capita government expenditure of approximately $1000-$4000 for 1% increase in the probability of local elimination would be required to make a lower threshold cost-effective., Conclusions: Lower Ag thresholds for stopping MDAs generally mean a higher probability of local elimination, reducing long-term costs and health impacts. However, they may also lead to an increased number of MDA rounds required to reach the lower threshold and, therefore, increased short-term costs. Collectively, our analyses highlight that lower target Ag thresholds have the potential to assist programs in achieving lymphatic filariasis goals., Competing Interests: Potential conflicts of interest.

Support groups can create environments that are conducive to healing and well-being, particularly for persons with stigmatizing chronic diseases. In 1998, the support group concept was adapted in Haiti for persons with disabling lymphedema caused by lymphatic filariasis (LF). The project was developed with the expectation that the support group model conceived in the developed world be interpreted and modified by persons affected with lymphedema in the Haitian setting. Initiated with modest financial support within a research initiative to eliminate LF, a total of 50 "Hope Clubs" were formed from 1998 to 2023 across seven communes (districts) located in 3 of Haiti's 10 regional Departments. Documented benefits of the support groups included improved limb self-care, decreased incidence of inflammatory episodes (adenolymphangitis), enhanced self-efficacy, economic benefit through microenterprise, and improved quality of life. Despite challenges of funding shortfalls, natural disasters, and political insecurity, persistence of LF support groups in Haiti highlights the crucial role of group ownership by affected persons and the freedom to reinvent the support group concept in light of local social, cultural, and economic conditions.

Backgrounds: This study assesses the impact of Water, Sanitation, and Hygiene (WASH) interventions on cholera understanding and hygiene practices in La Gonâve Island, Haiti. It examines the changes after implementing interventions in seven villages across the Downtown, Mountain, and Seaside regions., Methods: A retrospective investigation surveyed 210 school students from each region using a validated questionnaire. It assessed knowledge, attitudes, practices (KAP), and environmental aspects related to cholera and hygiene. Data analysis involved descriptive statistics and chi-square tests., Results: The study highlights significant disparities in education levels, toilet ownership, and healthcare access. Challenges in finding public toilets (86.67%) and accessing water sources (67.78%) are consistent across regions, with Seaside facing financial constraints (85.00%) and water cost concerns (91.67%). Attitudes toward hygiene vary, with the Mountain region having the highest 'Never' responses for handwashing (38.89%), and Downtown leading in water treatment practices (11.67%). There is a strong willingness to share health knowledge, particularly in Downtown (100.00%). Seaside (83.33%) and Downtown (73.33%) revealed a higher cholera awareness, while nearly half of Mountain students lacked knowledge (54.44%)., Conclusions: This study highlights significant disparities in WASH practices among La Gonâve's adolescents in Downtown, Mountain, and Seaside regions. Urgent interventions are crucial for improving sanitation, ensuring clean water access, and implementing targeted hygiene education, especially in the resource-constrained Mountain and Seaside areas. The findings underscore the vital roles of adolescents and schools in disseminating knowledge, with further research needed to explore intervention differences., Competing Interests: Declaration of Competing Interest We have no conflict of interest to declare., (Copyright © 2024 The Author(s).

Objective: This study explored the barriers and facilitators of mask-wearing behaviors during the pandemic in Taiwan, the United States, the Netherlands, and Haiti., Methods: Face-to-face interviews were conducted in Taiwan and online interviews were conducted with participants in the United States, the Netherlands, and Haiti., Results: In general, the habit of wearing a mask before coronavirus disease 2019 (COVID-19) was reported by Taiwanese participants. Additionally, Taiwanese participants perceived that wearing a mask was a social responsibility during the pandemic, suggesting that the collectivistic context might influence mask-wearing behavior. Unlike the Taiwanese population, some people in the United States and the Netherlands were reluctant to wear masks due to perceived restrictions on their freedom. Participants from Haiti mentioned that people who wore masks encountered violence, bullying, and discrimination. The results of this study suggest that political leadership and mask mandates have a strong impact on people's mask-wearing behavior., Conclusions: These findings have valuable implications for the design of diverse behavioral interventions to enhance mask-wearing as part of infectious disease preparedness. Additionally, the findings from these countries offer valuable insights for the development of effective public health interventions to enhance society's resilience during the current pandemic and future infectious disease outbreaks.

To address high HIV prevalence rates in Haiti, disseminating information about HIV transmission has been emphasized. Yet, after several decades, we do not know how effective HIV information dissemination has been in reducing HIV misconceptions. Using the 2005-06, 2012, and 2016-17 Haiti Demographic and Health Surveys and applying logistic regression, we found nuanced gender dynamics in endorsing HIV misconceptions over time. Among females at the bivariate level, the odds of endorsement of HIV misconceptions in 2012 (OR = 0.87, p  < 0.05) and 2016-17 (OR = 0.68, p  < 0.001) had declined compared to 2005-06. At the multivariate level, however, we observed that demographic factors suppressed the difference between 2005-06 and 2012, although those in 2016-17 (OR = 0.71, p  < 0.001) were still less likely to endorse HIV misconceptions. However, this relationship disappeared once we added behavioral factors (OR = 0.93, p  > 0.05). Among males, after controlling for demographic, socioeconomic, and behavioral factors at the multivariate level, those in 2012 (OR = 1.55, p  < 0.001) and 2016-17 (OR = 1.24, p  < 0.01) were more likely to endorse HIV misconceptions compared to men in 2005-06. We recommend that while improving women's access to HIV services, it is important to incorporate the HIV needs of males into the National HIV policy priority areas.

Objectives: The World Health Organization recommends the use of oral cholera vaccine (OCV) in cholera control efforts. Euvichol®, pre-qualified in 2015, is the leading component of the Global OCV stockpile, but data on its field effectiveness are limited. To evaluate Euvichol® vaccine effectiveness (VE), we conducted a case-control study between September 2018 to March 2020 following an OCV campaign in November 2017 in Haiti., Methods: Cases were individuals with acute watery diarrhea. Stool samples were tested by culture and real-time polymerase chain reaction of the Vibrio cholerae ctxA gene. Cases were matched to four community controls without diarrhea by residence, enrollment time, age, and gender, and interviewed for sociodemographics, risk factors, and self-reported vaccination. Cholera cases were analyzed by conditional logistic regression in the VE study. Non-cholera diarrhea cases were analyzed in a bias-indicator study., Results: We enrolled 15 cholera cases matched to 60 controls, and 63 non-cholera diarrhea cases matched to 249 controls. In the VE analysis, eight (53%) cases reported vaccination with any number of doses compared to 43 (72%) controls. Adjusted two-dose OCV VE was 69% (95% CI -71 to 94%)., Conclusions: Between 10-27 months after vaccination, Euvichol® was effective and similar to Shanchol™, suggesting that it can serve as one component of multi-sectoral comprehensive cholera control., Competing Interests: Declarations of competing interest The authors have no competing interests to declare., (Copyright © 2023 The Author(s).

Introduction: In the Latin America and Caribbean region, Haiti is one of the countries with the highest rates of HIV. Therefore, this study examined the factors associated with HIV testing among women in Haiti and trends in HIV testing in 2006, 2012, and 2016/17., Methods: Data from the last three Haitian Demographic and Health Surveys (2006, 2012, and 2016/17) were used. The analysis was restricted to women aged of 15-49 years who made their sexual debut. STATA/SE 16.0 was employed to analyze the data by computing descriptive statistics, Chi‑square, and multilevel regression model to describe the trends and identify factors associated with HIV testing in Haiti. P-value less than 0.05 was taken as a significant association., Results: HIV testing prevalence increased more than twofold from 2006 (8.8%) to 2017 (21.3%); however, it decreased by 11.6% between 2012 and 2016/17. Additionally, the results indicated that age, place of residence, region, education level, wealth index, mass media exposure, marital status, health insurance, age at first sex and number of sexual partners were significantly associated with HIV testing., Conclusions: To significantly increase HIV testing prevalence among women, the Haitian government must invest much more in their health education while targeting vulnerable groups (youth, women in union, and women with low economic status)., (© 2024.

The prevalence of diabetes mellitus in the Haitian American population remains an important question. A recent study revealed an alarming prevalence of 39.9%. To corroborate these data, between November 2021 and September 2023 a representative sample was collected among 401 Haitian Americans in Florida, Maryland, New Jersey, and New York. Results revealed a crude prevalence rate of 36.6% (95% CI 31.85, 41.55%). The age-adjusted prevalence was 29.7% (CI 19.71%, 39.63%). This study's prevalence is nearly double the 16.8% (Z=10.48, p&lt;.0001) rate in non-Hispanic African Americans and nearly two and a half times the 12.0% (Z=14.99, p&lt;.0001) rate in all Americans. The crude prevalence for undiagnosed diabetes mellitus was 13.38% (CI 10.19%, 17.14%), with 17.11% age-adjusted prevalence (CI 7.53%, 26.70%). The scope of the diabetes burden, especially the high rate of undiagnosed cases, indicates a need for better strategies for the prevention, screening, treatment, and management of diabetes among Haitian Americans.

Introduction: Although tobacco has harmful effects on the physical and mental health of individuals, its use remains significant, according to the World Health Organization. To understand this phenomenon, studies have been carried out in many countries around the world, while in Haiti where more than 5,000 people die each year due to tobacco use, little is known about the use of this substance. The aim of this study was to examine the prevalence and the factors associated with tobacco use in Haiti., Methods: We used data from the 2016/17 Haitian Demographic Health Survey. Both descriptive and multivariate analyses were conducted using STATA 16.0 software to assess the prevalence and identify factors associated with tobacco use. Results were reported as adjusted odds ratios with 95% confidence intervals. Statistical significance was declared at p < 0.05., Results: The prevalence of tobacco use was estimated at 9.8% (95% CI: 9.2-10.4) among men and 1.7% (95% CI: 1.5-1.9) among women. Although the prevalence of tobacco use was low among young people, it increased with age. Respondents aged 35 and above, with no formal education, non-Christians, divorced/separated/widowed, from poorest households, rural areas, "Aire Métropolitaine de Port-au-Prince" region, with high media exposure had a higher likelihood of tobacco use., Conclusion: The low prevalence of tobacco use among Haitian women and youth represents a public policy opportunity to prevent these vulnerable groups from starting smoking. Adult male smokers should also be targeted by appropriate policy to reduce the different health burdens associated with tobacco, both for the smokers and other people they may expose to passive smoking. Government and health sector stakeholders, along with community leaders, should create and enforce awareness strategies and rules to control advertisements that encourage irresponsible and health-risky consumption behaviors., (© 2023.

In the course of infectious disease outbreaks, barriers to accessing health care can contribute to preventable mortality. According to the Ministry of Health of Haiti (Ministère de la Santé Publique et de la Population [MSPP]), the 2010 cholera epidemic caused 7,936 deaths from October 2010 to December 2012 in Haiti alone. We seek to quantify the excess mortality attributable to patients not seeking care during the cholera outbreak in the Nord Department in 2010-2012. Using data from a community-based retrospective survey conducted by Doctors Without Borders (Médecins Sans Frontières [MSF]) in Northern Haiti, we used logistic regression to examine the association between healthcare utilization and fatality among household members with watery diarrhea in the Communes of Borgne, Pilate, Plaisance, and Port-Margot in the Nord Department. We found that failing to seek care resulted in a 5-fold increase in the case fatality ratio among infected individuals (26%) versus those who sought care (5%). Common concerns noted for why care was not sought included travel distance to treatment centers, not attributing watery diarrhea episodes to cholera, and being unsure where to seek health care for their watery diarrhea episodes within their Communes. In conclusion, addressing transportation and information needs could increase healthcare utilization and reduce lives lost during an outbreak., Competing Interests: The authors have declared that no competing interests exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Background: Failure to retain people living with HIV (PLHIV) in care remains a significant barrier to achieving epidemic control in Haiti, with as many as 30% lost from care within one year of starting treatment. Community-led monitoring (CLM) is an emerging approach of improving healthcare and accountability to service users, through a cycle of monitoring and advocacy. In 2020, a CLM program was launched in Haiti to identify barriers to retention and advocating for better health services., Methods: Data from the community-led monitoring program in Haiti were analyzed, from a sample of 65 healthcare facilities in the Nord, Artibonite, and Ouest departments collected from April 2021 to February 2022. Qualitative data from six community-based focus groups and 45 semi-structured individual interviews were analyzed., Results: Confidentiality and stigmatization emerged as barriers to care, particularly due to the separation of PLHIV from other patients in view of community members. To avoid identification, patients described traveling long distances, with the reimbursement of transportation costs described as being insufficient or unavailable. Costs of non-HIV clinical services were a frequent concern and respondents described a need for clinics to provide food during all patient visits. Stock-outs were a regular challenge; by contrast, treatment literacy did not emerge as a major barrier to retention., Conclusions: These findings represent the first instance, to our knowledge, of original data from a community-led monitoring program being published in any country. These findings suggest that improving treatment retention for PLHIV is dependent on improving the acceptability and affordability of healthcare services. Ensuring confidentiality is critical, particularly where stigma is high. Retention could be improved by systematically strengthening patient confidentiality protections throughout the healthcare system, providing patients with sufficient travel compensation and other incentives, and delivering wraparound services provided for free. Addressing these challenges will require ongoing advocacy for community-developed recommendations and solutions., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Policar et al.

Background: Limited data exist on the outcomes of patients requiring invasive ventilation or noninvasive positive pressure ventilation (NIPPV) in low-income countries. To our knowledge, no study has investigated this topic in Haiti., Objectives: We describe the clinical epidemiology, treatment, and outcomes of patients requiring NIPPV or intubation in an emergency department (ED) in rural Haiti., Methods: This is an observational study utilizing a convenience sample of adult and pediatric patients requiring NIPPV or intubation in the ED at an academic hospital in central Haiti from January 2019-February 2021. Patients were prospectively identified at the time of clinical care. Data on demographics, clinical presentation, management, and ED disposition were extracted from patient charts using a standardized form and analyzed in SAS v9.4. The primary outcome was survival to discharge., Findings: Of 46 patients, 27 (58.7%) were female, mean age was 31 years, and 14 (30.4%) were pediatric (age <18 years). Common diagnoses were cardiogenic pulmonary edema, pneumonia/pulmonary sepsis, and severe asthma. Twenty-three (50.0%) patients were initially treated with NIPPV, with 4 requiring intubation; a total of 27 (58.7%) patients were intubated. Among those for whom intubation success was documented, first-pass success was 57.7% and overall success was 100% (one record missing data); intubation was associated with few immediate complications. Twenty-two (47.8%) patients died in the ED. Of the 24 patients who survived, 4 were discharged, 19 (intubation: 12; NIPPV: 9) were admitted to the intensive care unit or general ward, and 1 was transferred. Survival to discharge was 34.8% (intubation: 22.2%; NIPPV: 52.2%); 1 patient left against medical advice following admission., Conclusions: Patients with acute respiratory failure in this Haitian ED were successfully treated with both NIPPV and intubation. While overall survival to discharge remains relatively low, this study supports developing capacity for advanced respiratory interventions in low-resource settings., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2023 The Author(s).)

Large-scale epidemics in resource-constrained settings disrupt delivery of core health services, such as routine immunization. Rebuilding and strengthening routine immunization programs following epidemics is an essential step toward improving vaccine equity and averting future outbreaks. We performed a comparative case study analysis of routine immunization program recovery in Liberia and Haiti following the 2014-16 West Africa Ebola epidemic and 2010s cholera epidemic, respectively. First, we triangulated data between the peer-reviewed and grey literature; in-depth key informant interviews with subject matter experts; and quantitative metrics of population health and health system functioning. We used these data to construct thick descriptive narratives for each case. Finally, we performed a cross-case comparison by applying a thematic matrix based on the Essential Public Health Services framework to each case narrative. In Liberia, post-Ebola routine immunization coverage surpassed pre-epidemic levels, a feat attributable to investments in surveillance, comprehensive risk communication, robust political support for and leadership around immunization, and strong public-sector recovery planning. Recovery efforts in Haiti were fragmented across a broad range of non-governmental agencies. Limitations in funding, workforce development, and community engagement further impeded vaccine uptake. Consequently, Haiti reported significant disparities in subnational immunization coverage following the epidemic. This study suggests that embedding in-country expertise within outbreak response structures, respecting governmental autonomy, aligning post-epidemic recovery plans and policies, and integrating outbreak response assets into robust systems of primary care contribute to higher, more equitable levels of routine immunization coverage in resource-constrained settings recovering from epidemics., Competing Interests: All authors have read the journal’s policy and have the following competing interests: SJR received compensation from the World Health Organization (WHO) for unrelated consultation services provided during the investigation and while preparing this manuscript. WHO was neither a sponsor of nor a partner in this investigation. This does not alter our adherence to PLOS ONE policies on sharing data and materials., (Copyright: © 2023 Ravi et al.

Background: Upon arrival, the prevalence of overweight and obesity is lower in new immigrants than their native counterparts in the U.S. With longer residency in the U.S., these differences converge over time, followed by higher prevalence among immigrants than native U.S. residents. Results from the Live Well project in the Greater Boston area demonstrate the viability of utilizing a culturally adapted, community-based participatory research (CBPR) approach to reduce weight gain among newly immigrated mother-child dyads., Methods: Haitian, Latina, and Brazilian mother-child dyads (n = 390), new to the U.S. (fewer than 10 years) were enrolled in a one- to two-year long CBPR lifestyle intervention that targeted dietary and physical activity behaviors. Attendance was recorded to establish dose. Demographics, anthropometrics, and relevant covariates were collected from participants at baseline, 6, 12, 18, and 24 months. Body Mass Index (BMI) was calculated using objectively measured height and weight. Linear mixed regression models were used to assess change in BMI and BMI z-score of mothers and children respectively., Results: At baseline, nearly 75% of mothers and 50% of children were either overweight or obese (BMI ≥ 25.0 and BMI z-score ≥ 85 th percentile, respectively). Only 20% of mothers attended all 12 intervention sessions in year 1. Using intent-to-treat analyses, no significant time, intervention, or time × intervention effects were observed for weight change of mothers or children at follow-up. Mothers in the highest quantile (those who attended all 12 intervention sessions) had significant reductions in BMI at 18 months (1.76 units lower, 95%CI: -3.14, -0.37) and 24 months (2.61 units, 95%CI -3.92, -1.29) compared to mothers in the lower quantiles, including those with no exposure. Such dose effects on BMI z-scores were not noted for children., Conclusions: Findings from Live Well demonstrate the viability of utilizing a CBPR approach to address overweight and obesity among immigrant mothers. Given the higher-than-expected prevalence of overweight and obesity among mother-child dyads by ~ 6 years of U.S. residency, and lower maternal participation rates in the intervention, additional research is necessary to identify the optimal intervention length, retention strategies, and approach to jointly support healthy maternal and child weight., (© 2023.

This exploratory study examined sex differences in psychosocial and demographic factors associated with sustained HIV viral suppression (SVS). The study population included 6,489 Miami-Dade Ryan White Program (RWP) clients receiving services during 2017; administrative data was analyzed. SVS was defined as having all viral load tests during 2017 below 200 copies/ml. Multilevel logistic regression models accounted for clustering by medical case management site. Models were stratified by sex. Overall, a higher proportion of females did not achieve SVS (23.5%) than males (18.1%). For females (n = 1,503), having acquired HIV perinatally and not having a partner oradult household member were associated with not achieving SVS. For males (n = 4,986), lacking access to food, Black or Haitian race/ethnicity, problematic substance use, and unknown physician were associated with not achieving SVS. For both sexes, younger age, lower household income, ever having an AIDS diagnosis, feeling depressed or anxious, and experiencing homelessness were associated with not achieving SVS. Elements of the transition from adolescent to adult HIV care that may differentially impact female clients and factors associated with disclosure should be explored further. Male clients may require additional support for food security. Improving culturally specific care for Haitian and non-Hispanic Black male clients should also be explored.

The 2010 cholera epidemic in Haiti was thought to have ended in 2019, and the Prime Minister of Haiti declared the country cholera-free in February 2022. On September 25, 2022, cholera cases were again identified in Port-au-Prince. We compared genomic data from 42 clinical Vibrio cholerae strains from 2022 with data from 327 other strains from Haiti and 1,824 strains collected worldwide. The 2022 isolates were homogeneous and closely related to clinical and environmental strains circulating in Haiti during 2012-2019. Bayesian hypothesis testing indicated that the 2022 clinical isolates shared their most recent common ancestor with an environmental lineage circulating in Haiti in July 2018. Our findings strongly suggest that toxigenic V. cholerae O1 can persist for years in aquatic environmental reservoirs and ignite new outbreaks. These results highlight the urgent need for improved public health infrastructure and possible periodic vaccination campaigns to maintain population immunity against V. cholerae.

In Haiti in 2017, the prevalence of serum vibriocidal antibody titers against Vibrio cholerae serogroup O1 among adults was 12.4% in Cerca-la-Source and 9.54% in Mirebalais, suggesting a high recent prevalence of infection. Improved surveillance programs to monitor cholera and guide public health interventions in Haiti are necessary.

Objective: Prior studies have demonstrated survival differences between Black women with endometrial cancer (EC) born in the US and Caribbean. Our objective was to determine if country of birth influences EC overall survival (OS) in disaggregated subpopulations of Black women., Methods: Using the Florida Cancer Data System, women with EC diagnosed from 1981 to 2017 were identified. Demographic and clinical information were abstracted. Women who self-identified as Black and born in the US (USB), Jamaica (JBB), or Haiti (HBB) were included. Statistical analyses were performed using chi-square, Cox proportional hazards models, and Kaplan-Meier methods with significance set at p < 0.05., Results: 3817 women met the inclusion criteria. Compared to USB, JBB and HBB had more high-grade histologies, more advanced stage disease, had a greater proportion of uninsured or Medicaid insured, and had a higher proportion of women who received chemotherapy (all p < 0.05). In multivariate analyses, age (HR 1.03 [1.02-1.05]), regional stage (HR 1.52 [1.22-1.89]), distant stage (HR 3.73 [2.84-4.89]), lymphovascular space invasion (HR 1.96 [1.61-2.39]), receipt of surgery (HR 0.47 [0.29-0.75]), and receipt of chemotherapy (HR 0.77 [0.62-0.95]) were independently associated with OS. Compared to USB, Haitian nativity was an independent negative predictor of OS when evaluating all histologies together (HR 1.54 [1.18-2.00]) and for endometrioid EC specifically (HR 1.77 [1.10-2.83]). Among women with serous EC, HBB had markedly worse median OS (18.5 months [13.4-46.5]) relative to USB (29.9 months [26.3-35.9]) and JBB (41.0 months, [34.1-82.6], p = 0.013)., Conclusion: Country of birth is associated with endometrial cancer survival in Black women, with HBB demonstrating worse outcomes., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest or funding to disclose., (Copyright © 2023 Elsevier Inc.

A Vibrio cholerae O1 outbreak emerged in Haiti in October 2022 after years of cholera absence. In samples from a 2021 serosurvey, we found lower circulating antibodies against V. cholerae lipopolysaccharide in children <5 years of age and no vibriocidal antibodies, suggesting high susceptibility to cholera, especially among young children.

Leptospirosis is an infectious illness encountered mostly in tropical climates and has been of particular concern in Haiti after natural disasters. Heavy rainfalls and natural disasters in combination with scarce resources to control and identify clusters of infections make certain populations and countries vulnerable. In some cases, patients who contract this disease may need air medical transport to hospitals that have a higher level of care. In this case report, a trio of cases is highlighted from an outbreak that required air transport to transfer patients to a facility with the availability of an intensive care unit. The goal of highlighting these cases is to increase the awareness of physicians and air transport providers to the manifestation and treatment of this disease and to provide pearls to stabilize patients during transport., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Air Medical Journal Associates.

Background: The city of Port-au-Prince, Haiti, is experiencing an epidemic of firearm injuries which has resulted in high burdens of morbidity and mortality. Despite this, little scientific literature exists on the topic. Geospatial research could inform stakeholders and aid in the response to the current firearm injury epidemic. However, traditional small-area geospatial methods are difficult to implement in Port-au-Prince, as the area has limited mapping penetration. Objectives of this study were to evaluate the feasibility of geospatial analysis in Port-au-Prince, to seek to understand specific limitations to geospatial research in this context, and to explore the geospatial epidemiology of firearm injuries in patients presenting to the largest public hospital in Port-au-Prince., Results: To overcome limited mapping penetration, multiple data sources were combined. Boundaries of informally developed neighborhoods were estimated from the crowd-sourced platform OpenStreetMap using Thiessen polygons. Population counts were obtained from previously published satellite-derived estimates and aggregated to the neighborhood level. Cases of firearm injuries presenting to the largest public hospital in Port-au-Prince from November 22nd, 2019, through December 31st, 2020, were geocoded and aggregated to the neighborhood level. Cluster analysis was performed using Global Moran's I testing, local Moran's I testing, and the SaTScan software. Results demonstrated significant geospatial autocorrelation in the risk of firearm injury within the city. Cluster analysis identified areas of the city with the highest burden of firearm injuries., Conclusions: By utilizing novel methodology in neighborhood estimation and combining multiple data sources, geospatial research was able to be conducted in Port-au-Prince. Geospatial clusters of firearm injuries were identified, and neighborhood level relative-risk estimates were obtained. While access to neighborhoods experiencing the largest burden of firearm injuries remains restricted, these geospatial methods could continue to inform stakeholder response to the growing burden of firearm injuries in Port-au-Prince., (© 2023.

Public experiences of COVID-19 pandemic lockdown differed dramatically between countries and socio-economic groups. Low-income countries raise unique empirical and ethical concerns about (1) the balance between benefits and social harms and (2) how explanatory disease models and everyday life realities influenced the experience and interpretation of lockdown itself. In this paper, we present qualitative data on community perceptions and experiences of the pandemic from a remote area of Haiti, with a focus on the 2020 lockdown. We conducted in-depth interviews with 30 community leaders in Grand'Anse Department, southwest Haiti, at two time periods: May 2020 and October-December 2021. We divide our results into five sections. First, our analysis showed that lockdown was widely considered ineffective at controlling COVID-19. Despite the lack of testing, community leaders believed most of the local population had caught COVID-19 in the first half of 2020, with limited reported mortality. Public concern about the pandemic largely ended at this time, overtaken by other socio-economic and political crises. Second, we found that popular explanations for the low fatality rate were related to various coping strategies: the strength of people's immune systems, use of natural prophylactic folk teas, beliefs about the virus, spiritual protections and the tropical weather. Third, we found that lockdown was widely seen to have not been appropriate for the Haitian context due to various challenges with compliance in the face of socio-economic vulnerability. Fourth, we found strong negative feelings about the social consequences of lockdown measures, which lasted from March-August 2020, including adverse effects on: food security, household income, education, health, and psychosocial well-being. Finally, these perceptions and experiences reinforced popular ideas that lockdown had been imposed by elites for financial and/or political gain, something that was also reflected in the discourse about the low vaccine acceptance rate. Our study showed that pandemic respiratory virus response in Haiti should better balance restrictive non-pharmaceutical interventions (NPIs) with existing socio-economic vulnerability. Local socio-behavioral dynamics and risk perceptions decrease the overall effectiveness of NPIs in fragile states and alternatives to lockdown, such as shielding the most vulnerable, are likely to be a more appropriate strategy., (Copyright © 2023 The Authors.

Purpose: The purpose of this study was to better understand the factors that influence the ability of batey adults to self-manage their type 2 diabetes mellitus (T2DM)., Methods: A qualitative descriptive approach was used to conduct in-depth, individual interviews in Spanish. Participants (n = 12) were health care workers and members of a nongovernmental organization (NGO) that provides direct diabetes care to batey residents via free, pop-up, mobile medical clinics. Conventional content analysis was used to identify categories and common themes in the data., Results: Participants described daily existence in the bateyes as a constant "scarcity of resources." Additionally, four themes and one subtheme emerged that participants felt impacted diabetes health outcomes and the ability of NGO health care workers to provide diabetes care., Conclusions: NGO members, while committed to serve and improve health outcomes for the batey population, often felt overwhelmed. Findings from this qualitative descriptive study may be used to inform novel interventions, which are needed, to enhance the diabetes outcomes of the batey residents who are living with T2DM. In addition, strategies are needed to build diabetes care infrastructure in the batey community.

Introduction: Cholera remains a significant public health threat for many countries, and the severity largely varies by the population and local conditions that drive disease spread, especially in endemic areas prone to natural disasters and flooding. Epidemiological models can provide useful information to military planners for understanding disease spread within populations and the effectiveness of response options for preventing the transmission among deployed and stationed personnel. This study demonstrates the use of epidemiological modeling to understand the dynamics of cholera transmission to inform emergency planning and military preparedness in areas with highly communicable diseases., Materials and Methods: Areas with higher probability for a potential cholera outbreak in Haiti followed by a natural disaster were identified. The hotspots were then used to seed an extended compartmental model, EpiGrid, to simulate notional spread scenarios of cholera originating in three distinct areas in Haiti. Disease parameters were derived from the 2010 cholera outbreak in Haiti, and disease spread was simulated over a 12-week period under uncontrolled and controlled spread., Results: For each model location, scenarios of mitigated (intervention with 30% transmission reduction via international aid) and unmitigated (without intervention) are simulated. The results depict the geographical spread and estimate the cumulative cholera infection for each notional scenario over the course of 3 months. Disease transmission differs considerably across origin site with an outbreak originating in the department of Nippes spanning the largest geographic area and resulting in the largest number of cumulative cases after 12 weeks under unmitigated (79,518 cases) and mitigated (35,667 cases) spread scenarios., Conclusions: We modeled the notional re-emergence and spread of cholera following the August 2021 earthquake in Haiti while in the midst of the global COVID-19 pandemic. This information can help guide military and emergency response decision-making during an infectious disease outbreak and considerations for protecting military personnel in the midst of a humanitarian response. Military planners should consider the use of epidemiological models to assess the health risk posed to deployed and stationed personnel in high-risk areas., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2022.

Background: In Haiti, cardiovascular disease is a leading cause of morbidity and mortality, with congenital and rheumatic heart disease comprising a large portion of disease burden. However, domestic disparities in cardiac care access and their impact on clinical outcomes remain poorly understood. We analyzed population-level sociodemographic variables to predict cardiac care outcomes across the 10 Haitian administrative departments., Methods: This cross-sectional study combined data from a 2016-17 Haitian national survey with aggregate outcomes from the Haiti Cardiac Alliance (HCA) database (n = 1817 patients). Using univariate and multivariable regression analyses, the proportion of HCA patients belonging to each of three clinical categories (active treatment, lost to follow-up, deceased preoperatively) was modeled in relation to six population-level variables selected from national survey data at the level of the administrative department., Results: In univariate analysis, higher department rates of childhood growth retardation were associated with a lower proportion of patients in active care (OR = 0.979 [0.969, 0.989], p = 0.002) and a higher proportion of patients lost to follow-up (OR = 1.016 [1.006, 1.026], p = 0.009). In multivariable analysis, the proportion of department patients in active care was inversely associated with qualified prenatal care (OR = 0.980 [0.971, 0.989], p = 0.005), and child growth retardation (OR = 0.977 [0.972, 0.983]), p = 0.00019). Similar multivariable results were obtained for department rates of loss to follow-up (child growth retardation: OR = 1.018 [1.011, 1.025], p = 0.002; time to nearest healthcare facility in an emergency: OR = 1.004 [1.000, 1.008, p = 0.065) and for preoperative mortality (prenatal care: OR = 0.989 [0.981, 0.997], p = 0.037; economic index: OR = 0.996 [0.995, 0.998], p = 0.007; time to nearest healthcare facility in an emergency: OR = 0.992 [0.988, 0.996], p = 0.0046)., Conclusions: Population-level survey data on multiple variables predicted domestic disparities in HCA clinical outcomes by region. These findings may help to identify underserved areas in Haiti, where increased cardiac care resources are required to improve health equity. This approach to analyzing clinical outcomes through the lens of population-level survey data may inform future health policies and interventions designed to increase cardiac care access in Haiti and other low-income countries., (© 2023.

Objectives: Haiti remains a principal placement country for intercountry adoptees to the United States. This project reports the health status of children adopted from Haiti arriving to the U.S. and compares them to intercountry adoptees from other regions., Methods: A retrospective chart review was conducted of adoptees placed in the U.S. from Haiti (n=87), age and sex matched with intercountry adoptees placed in the U.S. from Asia (n=87) and Latin America (n=87) between January 2010 and November 2019. Data on immunization status, contagious diseases, and nutrition and growth were analyzed via linear, logistic, and multinomial regression., Results: After adjusting for age, sex, and standardized height, children adopted from Haiti, compared to adoptees from Latin America and Asia, demonstrated a lack of immunity to hepatitis B (OR=5.89;6.87), increased immunity to hepatitis A (OR=0.38;0.30), infection by two or more parasites (OR=8.43;38.48), high lead levels (OR=23.79;7.04), and anemia (OR=15.25;9.18). Unexpectedly, children adopted from Haiti had greater standardized height (-1.28 vs. -1.82 and -2.13) and standardized weight (-0.32 vs. -0.57 and -1.57) than their counterparts from Latin America and Asia., Conclusions: Children adopted from Haiti face complex medical challenges undoubtedly related to the country's low socioeconomic status (SES) and the impact of recurrent natural disasters and governmental neglect on public health infrastructure. Appropriate care is critical in preventing and avoiding transmission of infectious diseases in adoptees and family members.

Background: Same-day HIV testing and antiretroviral therapy (ART) initiation is being widely implemented. However, the optimal timing of ART among patients with tuberculosis (TB) symptoms is unknown. We hypothesized that same-day treatment (TB treatment for those diagnosed with TB; ART for those not diagnosed with TB) would be superior to standard care in this population., Methods and Findings: We conducted an open-label trial among adults with TB symptoms at initial HIV diagnosis at GHESKIO in Haiti; participants were recruited and randomized on the same day. Participants were randomized in a 1:1 ratio to same-day treatment (same-day TB testing with same-day TB treatment if TB diagnosed; same-day ART if TB not diagnosed) versus standard care (initiating TB treatment within 7 days and delaying ART to day 7 if TB not diagnosed). In both groups, ART was initiated 2 weeks after TB treatment. The primary outcome was retention in care with 48-week HIV-1 RNA <200 copies/mL, with intention to treat (ITT) analysis. From November 6, 2017 to January 16, 2020, 500 participants were randomized (250/group); the final study visit occurred on March 1, 2021. Baseline TB was diagnosed in 40 (16.0%) in the standard and 48 (19.2%) in the same-day group; all initiated TB treatment. In the standard group, 245 (98.0%) initiated ART at median of 9 days; 6 (2.4%) died, 15 (6.0%) missed the 48-week visit, and 229 (91.6%) attended the 48-week visit. Among all who were randomized, 220 (88.0%) received 48-week HIV-1 RNA testing; 168 had <200 copies/mL (among randomized: 67.2%; among tested: 76.4%). In the same-day group, 249 (99.6%) initiated ART at median of 0 days; 9 (3.6%) died, 23 (9.2%) missed the 48-week visit, and 218 (87.2%) attended the 48-week visit. Among all who were randomized, 211 (84.4%) received 48-week HIV-1 RNA; 152 had <200 copies/mL (among randomized: 60.8%; among tested: 72.0%). There was no difference between groups in the primary outcome (60.8% versus 67.2%; risk difference: -0.06; 95% CI [-0.15, 0.02]; p = 0.14). Two new grade 3 or 4 events were reported per group; none were judged to be related to the intervention. The main limitation of this study is that it was conducted at a single urban clinic, and the generalizability to other settings is uncertain., Conclusions: In patients with TB symptoms at HIV diagnosis, we found that same-day treatment was not associated with superior retention and viral suppression. In this study, a short delay in ART initiation did not appear to compromise outcomes., Trial Registration: This study is registered with ClinicalTrials.gov NCT03154320., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Dorvil et al.

Targeting malaria interventions in elimination settings where transmission is heterogeneous is essential to ensure the efficient use of resources. Identifying the most important risk factors among persons experiencing a range of exposure can facilitate such targeting. A cross-sectional household survey was conducted in Artibonite, Haiti, to identify and characterize spatial clustering of malaria infections. Household members (N = 21,813) from 6,962 households were surveyed and tested for malaria. An infection was defined as testing positive for Plasmodium falciparum by either a conventional or novel highly sensitive rapid diagnostic test. Seropositivity to the early transcribed membrane protein 5 antigen 1 represented recent exposure to P. falciparum. Clusters were identified using SaTScan. Associations among individual, household, and environmental risk factors for malaria, recent exposure, and living in spatial clusters of these outcomes were evaluated. Malaria infection was detected in 161 individuals (median age: 15 years). Weighted malaria prevalence was low (0.56%; 95% CI: 0.45-0.70%). Serological evidence of recent exposure was detected in 1,134 individuals. Bed net use, household wealth, and elevation were protective, whereas being febrile, over age 5 years, and living in either households with rudimentary wall material or farther from the road increased the odds of malaria. Two predominant overlapping spatial clusters of infection and recent exposure were identified. Individual, household, and environmental risk factors are associated with the odds of individual risk and recent exposure in Artibonite; spatial clusters are primarily associated with household-level risk factors. Findings from serology testing can further strengthen the targeting of interventions.

Objectives: This study examines body composition and nutritional status of Haitian children and adolescents living in urban and peri-urban communities in the Dominican Republic to provide estimates of stunting, underweight, overweight, and obesity for this under-researched population., Methods: Anthropometric measures including height, weight, mid-upper arm circumference, and skinfold thicknesses (triceps and subscapular) were obtained for Kreyòl-speaking school-aged children (n  = 105, males = 51, females = 54, ages 4-17). Z-scores for height, body mass index (BMI), and upper arm muscle area by height were used to classify children's nutritional status. Variation among sex and age groups was assessed., Results: Relatively low rates of stunting (4.8%) and thinness (2.9%) were identified. The total prevalence of overweight was 5.7% and 2.9% of children were classified as having obesity. Girls had a higher prevalence of overweight/obesity and risk of overweight (16.7%) than boys (3.9%, p = .033)., Conclusions: The prevalence of overweight and obesity (8.6%) suggests that Haitian children in these urban and peri-urban communities are experiencing the nutrition transition. Interventions should address the development of excess weight, especially among girls, as well as persisting undernutrition and stunting., (© 2023 Wiley Periodicals LLC.)

Background: CKD is a major cause of morbidity and mortality in lower-income countries. However, population-based studies characterizing the epidemiology of CKD in these settings are lacking. The study objective was to describe the epidemiology of CKD in a population-based cohort in urban Haiti, including estimates of the prevalence by CKD stage, the magnitude of associated factors with CKD, and the proportion on guideline-recommended treatment., Methods: We assessed the prevalence of CKD and associated risk factors in the population-based Haiti Cardiovascular Disease Cohort. We analyzed cross-sectional data from 2424 adults who completed a clinical examination, risk factor surveys, and laboratory measurements for serum creatinine, urinary albumin, and urinary creatinine. We compared our results with US estimates from the National Health and Nutrition Examination Survey. CKD was defined as either a reduced eGFR <60 ml/min per 1.73 m 2 or urinary albumin-to-creatinine ratio ≥30 mg/g according to the Kidney Disease Improving Global Outcomes guidelines. Multivariable logistic regression identified associated factors with CKD., Results: The mean age was 42 years, 57% of participants were female, and 69% lived in extreme poverty on ≤1 US dollar per day. The age-standardized prevalence of CKD was 14% (95% confidence interval [CI], 12% to 15%). The age-standardized prevalence of reduced eGFR and elevated urinary albumin-to-creatinine ratio was 3% (95% CI, 2% to 4%) and 11% (95% CI, 10% to 13%), respectively. Diabetes (adjusted odds ratio, 4.1; 95% CI, 2.7 to 6.2) and hypertension (adjusted odds ratio, 2.9; 95% CI, 2.0 to 4.2) were significantly associated with CKD. Only 12% of participants with CKD and albuminuria were on guideline-recommended agents, such as angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers., Conclusions: In a large population-based cohort of Haitian adults, CKD was highly associated with both diabetes and hypertension. The proportion of participants with CKD on treatment was low, underscoring the need for strengthening clinical management and nephrology care health infrastructure in Haiti., Clinical Trial Registry Name and Registration Number: A Longitudinal Cohort Study to Evaluate Cardiovascular Risk Factors and Disease in Haiti, NCT03892265 ., (Copyright © 2023 by the American Society of Nephrology.)
