Introduction: Epidemiological transition to NCDs is a challenge for fragile health systems in the Caribbean. The Congregations Taking Action against NCDs (CONTACT) Study intervention proposes that trained health advocates (HAs) from places of worship (PoWs), supervised by nurses at nearby primary healthcare centres (PHCs), could facilitate access to primary care among vulnerable communities. Drawing on participatory and systems thinking, we explored the capacity of local PHCs in three Caribbean countries to support this intervention.

In the English-speaking Caribbean, an estimated 46% of men and 61% of women are currently overweight or obese, and 8% of children younger than 5 years are also overweight. To combat this worsening epidemic, driven by unhealthy dietary patterns, the Heads of Government of the Caribbean Community (CARICOM) issued the 2007 Port-of-Spain Declaration, which included mandates on the provision of healthy school meals, promotion of healthy dietary patterns, and reintroduction of physical education in schools. These mandates are aligned with evidence-based approaches used in childhood obesity prevention programs.

Diabetes and obesity present a high and increasing burden of disease in the Caribbean that have failed to respond to prevention policies and interventions. These conditions are the result of a complex system of drivers and determinants that can make it difficult to predict the impact of interventions. In partnership with stakeholders, we developed a system dynamics simulation model to map the system driving diabetes and obesity prevalence in the Caribbean using Jamaica as a test case.

The Caribbean is experiencing a worsening epidemic of obesity and noncommunicable diseases (NCDs) and it has the worst rates of premature mortality from cardiovascular diseases in the region of the Americas. Creating enabling environments to improve dietary diversity would help reduce obesity and diet-related NCDs. The Improving Household Nutrition Security and Public Health in the CARICOM project aimed to increase dietary diversity in the Caribbean, and to determine and implement effective, gender-sensitive interventions to improve food sovereignty, household food security, and nutrition in CARICOM states.

The World Health Organization (WHO) Global Action Plan on Physical Activity recommends adopting a systems approach to implementing and tailoring actions according to local contexts. We held group model-building workshops with key stakeholders in the Caribbean region to develop a causal loop diagram to describe the system driving the increasing physical inactivity in the region and envision the most effective ways of intervening in that system to encourage and promote physical activity. We used the causal loop diagram to inform how the WHO Global Action Plan on Physical Activity might be adapted to a local context.

Article Synopsis
  • Analysis of dengue virus (DENV) infections in Barbados utilized national data from 3,994 confirmed cases, revealing a low case fatality rate of 0.4% and an annual prevalence range of 27.5 to 453.9 cases per 100,000 in febrile patients.
  • Dengue fever (DF) cases showed seasonal fluctuations, with lower transmission during the dry season and a peak in October during the rainy season, alongside three significant epidemics identified in 2010, 2013, and possibly 2016.
  • The majority of DF cases occurred among individuals aged 10-19, and the study highlighted the need for improved public health strategies while considering similarities between dengue and COVID

Many Small Island Developing States of the Caribbean experience a triple burden of malnutrition with high rates of obesity, undernutrition in children, and iron deficiency anemia in women of reproductive age, driven by an inadequate, unhealthy diet. This study aimed to map the complex dynamic systems driving unhealthy eating and to identify potential points for intervention in three dissimilar countries. Stakeholders from across the food system in Jamaica (n = 16), St.

Objectives: Noncommunicable diseases (NCDs) are a threat to social and economic development, including in the Caribbean. In 2007 the Caribbean Community (CARICOM) held the world's first-ever summit of heads of government on NCD prevention and control and issued the landmark Declaration of Port-of-Spain: Uniting to Stop the Epidemic of Chronic NCDs. The objectives of this paper are to provide an overview of a formal evaluation of the Declaration and to highlight key findings that could inform further implementation of the Declaration's 15 mandates.

This report examines the experiences of Small Island Developing States in the Caribbean- Barbados, Dominica, Jamaica, and in the Pacific- Fiji, Nauru, and Tonga with specific governmental regulatory measures to reduce the risk of obesity and associated diet-related chronic noncommunicable diseases (NCDs), as well as the obstacles and opportunities encountered. Guided by the diet-related indicators of the World Health Organization (WHO) Noncommunicable Diseases Progress Monitor 2017, the authors reviewed legislation, country reports, articles, and the databases of WHO and the World Trade Organization to identify relevant regulatory measures and to establish the extent of implementation in the selected countries. Obesity prevalence ranged from 25.

Objectives: In 2007, the Caribbean Community (CARICOM) convened the world's first-ever heads of government summit on noncommunicable diseases (NCDs) and issued the landmark Declaration of Port-of-Spain: Uniting to Stop the Epidemic of Chronic NCDs. Since then, ministry of health (MoH) focal points in each country have self-reported annually on their NCD efforts, using a 26-indicator grid created to assess implementation of the Declaration. Our objective was to assess the validity of those grid responses, as compared to information from in-depth interviews and document reviews.

Like many nations in the Americas, the countries of the Caribbean are facing increasing morbidity and mortality associated with noncommunicable diseases (NCDs). In 2007, based on advocacy by Sir George Alleyne and others, the Caribbean Community (CARICOM) convened the first in the world Heads of Government NCDs Summit. This summit issued the Port of Spain Declaration that served not only as a rallying point to accelerate the regional NCDs response, but also as a catalyst for the first United Nations high-level meeting on NCDs in September 2011.

Background: The World Health Organization has advocated for sugar-sweetened beverage (SSB) taxes as part of a broader non-communicable disease prevention strategy, and these taxes have been recently introduced in a wide range of settings. However, much is still unknown about how SSB taxes operate in various contexts and as a result of different tax designs. In 2015, the Government of Barbados implemented a 10% ad valorem (value-based) tax on SSBs.
