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.

Article Synopsis
  • A study in Port-au-Prince, Haiti, found that 14.7% of adults have cardiovascular disease (CVD), with prevalent conditions including heart failure (11.9%) and stroke (2.4%).
  • The research involved gathering diverse health data from over 3,000 participants and identified key risk factors such as hypertension and obesity linked to heart failure.
  • The findings reveal a significant presence of early-onset heart failure in Haiti, highlighting the need for tailored health policies in low- and middle-income countries based on local epidemiological data.

Neighborhood factors have been associated with health outcomes, but this relationship is underexplored in low-income countries like Haiti. We describe perceived neighborhood cohesion and perceived violence using the Neighborhood Collective Efficacy and the City Stress Inventory scores. We hypothesized lower cohesion and higher violence were associated with higher stress, depression, and hypertension.

Article Synopsis
  • Cardiovascular disease, particularly heart failure (HF), significantly impacts low- and middle-income countries, with insufficient data on its prevalence and risk factors in these regions.
  • A population study in Port-au-Prince, Haiti, involving 2981 participants, revealed an age-standardized HF prevalence of 3.2%, with prominent risk factors including age, hypertension, obesity, and poverty.
  • The one-year mortality rate for HF patients was markedly higher at 6.6% compared to 0.8% for non-HF individuals, highlighting a severe health concern in the Haitian population.

Article Synopsis
  • Diabetes is a growing concern in low- and middle-income countries, and a study was conducted to assess its prevalence among adults in Port-au-Prince, Haiti, due to limited local data.
  • The study involved 3,005 adults aged 18 and older, collecting data on demographics, health behaviors, and clinical evaluations to identify diabetes prevalence and its associated factors.
  • Findings showed a diabetes prevalence of 5.4%, with older age and higher body mass index (BMI) being significant risk factors, indicating the need for improved healthcare measures targeting these vulnerable groups in Haiti.

Cardiovascular disease (CVD) is the number one cause of death in low-income countries including Haiti, with hypertension (HTN) being the leading risk factor. This study aims to identify gaps in the HTN continuum of screening, diagnosis, treatment, and blood pressure (BP) control. Sociodemographic and clinical data were collected from a population-based sample of adults ≥18 years in Port-au-Prince (PAP) from March 2019 to April 2021.

Cardiovascular disease is the leading cause of death in lower-income countries including Haiti. Environmental lead exposure is associated with high blood pressure and cardiovascular mortality in high-income countries but has not been systematically measured and evaluated as a potential modifiable cardiovascular risk factor in lower-income countries where 6.5 billion people reside.

Background: This study aimed to evaluate the clinical and epidemiologic profile of congestive heart failure at the principal free-care hospital in Haiti. Cardiovascular disease represents the most prevalent cause of admissions to the medical service of the University Hospital of the State of Haiti. No previous study has examined the demographics of congestive heart failure in urban Haiti.

Objectives: Since 1996, 1 to 4 annual training missions have been carried out to train Haitian otorhinolaryngology (ENT) and cervicofacial surgery residents by the association Liens Otorhinolaryngology Ayti (LOA). Until 1996, ENT was practiced and taught by ophthalmologists. The aim of this article is to describe the contributions and limitations of LOA in training of Haitian resident physicians and the creation of the ENT specialty in Haiti.
