Jamaica continues to struggle with significant rates of kidney disease, resulting in a formidable public health challenge for the nation. 

Recent studies shed light on the prevalence of this condition, revealing alarming trends across various demographic groups. According to data from the Ministry of Health and Wellness in Jamaica, kidney disease affects individuals of all ages, particularly among the middle-aged and elderly populations. 

Among individuals aged 45 to 64 years old, the incidence of kidney disease remains notably high, accounting for approximately 60 per cent of reported cases. Additionally, among those aged 65 and above, the incidence rate rises even higher, elucidating the impact of ageing on kidney health.

What does Jamaica’s future look like without any change

Dr Yeates, medical director of Rapha Dialysis Centre, said in a 2023 interview with the Jamaica Information Service that “an estimated one in seven Jamaicans will develop kidney disease at some point in their lives, consequent on the prevalence of hypertension and diabetes in the country. He said that hypertension and diabetes are the main causes of persons developing chronic kidney disease (CKD) in Jamaica.”

He also said, “We know for certain that 327 people to a million will develop chronic kidney disease every year. Hence the reason we have to make people aware of the issue of chronic kidney disease and the importance of preventing it, recognising it and treating it,” a devastating revelation on where the nation and by large the world is headed.

Effect on men vs women

Gender disparities also emerge in the statistics, with men exhibiting a slightly higher prevalence of kidney disease compared to women. While the exact reasons for this difference warrant further investigation, potential factors such as lifestyle habits, occupational exposures, and genetic predispositions may contribute to this discrepancy.

 Hypertension and diabetes

Among the causes of kidney disease in Jamaica, hypertension and diabetes stand out as primary drivers. Hypertension, or high blood pressure, remains a pervasive health issue in Jamaica, affecting approximately one in every four adults. The chronic elevation of blood pressure can exert damaging effects on the kidneys over time, leading to renal dysfunction and eventual kidney disease.

Similarly, diabetes mellitus, particularly Type 2 diabetes, represents a significant risk factor for kidney disease in Jamaica. With an estimated prevalence of around 10.2 per cent among adults, diabetes poses a dual threat to kidney health by impairing blood sugar regulation and fostering the development of diabetic nephropathy, a progressive kidney condition. Jamaicans who suffer from either diabetes or hypertension are urged to do annual screenings. 

Other contributing factors to kidney disease in Jamaica include obesity, unhealthy dietary patterns, inadequate access to healthcare services, and limited public awareness about kidney health. 

The effect on children

Though childhood kidney disease accounts for a small percentage of those affected, it is still worth mentioning that poor habits that start from young carry over into adulthood. Jamaica has one of the highest obesity rates in the region, especially in women. And as stated above, obesity is linked to both hypertension and diabetes, which can lead to kidney disease. That said, curbing bad eating habits from early should be considered. As the Jamaican saying goes, “prevention is always better than cure”.

Early signs of kidney disease

According to the National Kidney Foundation, some early signs include but are not limited to:

• Tiredness, having less energy or having trouble concentrating,
• Insomnia
• Dry and itchy skin
• Frequent urination
• Bloody in your urine
• Foamy urine
• Persistent puffiness around your eyes
• Swollen ankles and feet.

An increase in water intake, about 1.5 to 2.0 litres a day, is the usual recommendation for maintaining healthy kidney function. 

By empowering individuals with knowledge about risk factors and preventive measures, Jamaica can strive towards a healthier future where kidney disease no longer exerts such a profound impact on its people.
