Diabetes remains a major public health concern in Jamaica, where more than 235,000 adults are estimated to be living with the condition, with almost one in four cases going undiagnosed. The disease can cause serious damage to the heart, blood vessels, kidneys, eyes and nerves, placing a significant burden on individuals, families and healthcare systems.
The International Diabetes Federation’s 2025 Diabetes Atlasestimates that 235,600 Jamaican adults age 20 to 79 were living with diabetes in 2024. This represents an estimated prevalence of 11.6 per cent, while the age-standardised prevalence was 12.5 per cent. The federation further estimates that 24.3 per cent of people with diabetes in Jamaica are unaware that they have the condition. Diabetes was also associated with an estimated 3,622 deaths among adults in this age group during 2024.
The figures reflect a wider regional and global challenge. An estimated 589 million adults worldwide are living with diabetes, including approximately 56.2 million across North America and the Caribbean. In the region, an estimated 29.1 per cent of adults with diabetes remain undiagnosed.
While age and family history can influence a person’s risk, everyday lifestyle choices also play an important role in prevention. A balanced diet, regular physical activity and maintaining a healthy weight can work together to improve blood glucose control, support heart health, and reduce the likelihood of developing type 2 diabetes.
Dr Sanjeev Kumar Gulati, FACC, executive deputy Healthy eating is most effective when it becomes a consistent part of everyday life.
Portion control is another important consideration. In PREDIMED-Plus, participants in the intervention group followed a Mediterranean diet with a moderate reduction in daily calorie intake. After six years, they lost an average of 3.3 kilograms and reduced their waist circumference by 3.6 centimetres.

“Portion awareness and control can help people manage their energy intake while maintaining a varied diet. However, individual calorie needs differ according to age, activity level, health status and personal goals,” he said.
Physical activity was also a central part of the intervention. Participants received guidance on moderate exercise, including brisk walking and strength training. The combination of dietary changes and physical activity produced greater benefits than the Mediterranean eating pattern alone.
“The study paired dietary changes with guidance on moderate physical activity, including brisk walking and strength training. Regular movement also supports heart health, blood pressure, weight management and insulin sensitivity,” he said.
Walking, cycling, swimming and resistance exercises can all contribute to an active routine. The important consideration is finding activities that can be maintained consistently and safely.
Nutrition and physical activity reinforce each other. Together, they can improve several cardiovascular and metabolic risk factors while helping individuals maintain a healthier weight.
Recognising personal risk is equally important. Age, excess weight, family history, physical inactivity and certain metabolic conditions can increase the likelihood of developing type 2 diabetes. Because diabetes and cardiovascular disease share many risk factors, regular medical visits provide an opportunity to assess blood glucose, blood pressure, cholesterol, kidney function, and other indicators of metabolic and cardiovascular health.
“The risk factors for diabetes and cardiovascular disease often overlap, so regular medical check-ups are important. These visits provide an opportunity to review blood glucose, blood pressure, cholesterol and kidney function, and to identify concerns that may require further attention,” Dr Gulati said.
The high proportion of undiagnosed cases in Jamaica makes screening particularly important. People may have elevated blood glucose without experiencing obvious symptoms, meaning routine checks can help identify the condition earlier and reduce the likelihood of complications.
Individuals who already have prediabetes or other risk factors can work with their healthcare teams to develop eating and activity plans suited to their needs. Those living with heart disease, experiencing heart failure symptoms or managing multiple cardiovascular risk factors may require a more personalised approach and closer medical follow-up.
“People with prediabetes or additional risk factors should work with their healthcare team to develop a plan that meets their individual needs. Those with existing heart disease or multiple cardiovascular risk factors may need closer medical supervision. Lifestyle changes should complement, rather than replace, prescribed medication and professional medical advice,” he said.
Reducing diabetes risk involves more than changing what is on the plate. Combining nutritious eating, regular physical activity and weight management can help protect the heart, improve metabolic health and reduce the likelihood of developing type 2 diabetes. Alongside routine monitoring of blood glucose, blood pressure and cholesterol, these habits can make a lasting contribution to better health throughout adulthood.
