Chronic Kidney Disease Increases in NJ

On Dec 10, 2025

Chronic kidney disease is on the rise in New Jersey, with a nearly 60% increase in prevalence of the illness among patients admitted to the hospital since 2016, according to a new data analysis by the New Jersey Hospital Association  (NJHA).

The growing number of New Jerseyans diagnosed with the illness spans all ages, genders and racial and ethnic groups, according to the report by NJHA’s Center for Health Analytics, Research and Transformation (CHART). However, Black New Jerseyans have a disproportionately high mortality rate, the data shows.

Chronic kidney disease, or CKD, is progressive damage and loss of function in the kidneys. It’s linked to a number of chronic health conditions including diabetes, high blood pressure and obesity – considered to be key factors in its rise. In advanced stages, CKD can lead to kidney failure, requiring dialysis or a transplant.

NJHA examined hospital discharge data from 2016 to 2024 to identify diagnosis codes related to CKD, along with age-adjusted death rates from the N.J. State Health Assessment Data (NJSHAD). Key findings include:

• In 2024, 18.3% of New Jersey patients admitted to the hospital had CKD.
• CKD prevalence is higher among males. The prevalence rate increased from 4.9% in 2016 to 7.7% in 2024 – a 57.4% jump. Women experienced a rise in prevalence from 3.1% in 2016 to 4.8% in 2025 – a slightly higher increase compared with men at 57.9%.
• Older New Jerseyans aged 65-plus also experienced higher prevalence of CKD – 16% in 2024, compared with 5.8% for those aged 45-64.
• All races experienced a rise in CKD over the study period, but Black and White patients consistently had the highest prevalence rates compared with other groups.
• While mortality rates were largely stable between 2000 and 2023 – or even declined slightly – CKD mortality was consistently higher for Black New Jerseyans. Black males had the highest age-adjusted mortality rate (38.9 per 100,000 population) compared with the average for all males of 18.7. For Black women, the age-adjusted mortality rate was 27.9, compared with an average of 14.2 for all women.

“The complex picture surrounding CKD – rising incidence and improved mortality rates overall – may be shaped by improved diagnosis and treatment for CKD,” said NJHA President and CEO Cathy Bennett. “But the disparate impact for Black New Jerseyans demands greater attention to issues of access, equity and the social factors that impact health in our communities.”
