Global study reveals rising chronic kidney disease burden in women

Power kidney illness is now the seventh main reason behind dying amongst noncommunicable ailments globally, affecting 11–13% of the grownup inhabitants. Whereas ladies constantly present a better prevalence of CKD than males, most epidemiological analyses have pooled the sexes collectively, leaving the distinct patterns of CKD in ladies poorly understood. Girls additionally face distinctive organic vulnerabilities-from sooner illness development after menopause to intergenerational dangers linked to being pregnant complications-that demand tailor-made consideration. 

To handle these gaps, Professor Lin Solar and Professor Zhifeng Sheng from The Second Xiangya Hospital of Central South College performed the primary world evaluation devoted to CKD in ladies. Drawing on International Burden of Illness 2021 information, the staff quantified tendencies by age, CKD subtype, sociodemographic stage, and threat issue, and additional examined the cardiovascular penalties of impaired kidney perform. Their findings had been printed within the Chinese language Medical Journal on June 1, 2026. 

1. CKD in ladies: An underestimated “silent killer”

“Our evaluation exhibits that the burden of CKD in ladies has not solely grown, however has additionally reworked in character. Metabolic drivers-diabetes, hypertension, and obesity-now form the trajectory of the illness,” explains Prof. Solar. The variety of ladies dwelling with CKD climbed from about 188 million in 1990 to 359 million in 2021. Over the identical interval, deaths from CKD in ladies rose by 180.89%, and disability-adjusted life years (DALYs) elevated by 114.00%. The age-standardized mortality and DALY charges each confirmed steady upward tendencies, underscoring the worsening severity of the illness even after accounting for inhabitants progress and ageing. 

2. Reproductive-age and postmenopausal ladies bear the main burden 

The examine recognized two populations on the coronary heart of this world pattern. Postmenopausal ladies (aged 50 years and older) bore the heaviest burden, accounting for almost 90% of CKD-related deaths and about 73% of DALYs amongst ladies in 2021; each their age-standardized mortality fee (64.03 per 100,000) and DALY fee (1,493.31 per 100,000) continued to rise over the 32-year interval. On the identical time, ladies of reproductive age (15–49 years) emerged as a fast-growing threat group: their prevalent circumstances elevated by 64.01%, and, uniquely amongst age teams, their age-standardized prevalence fee continued to climb (common annual share change, 0.13%). 

3. From threat to coronary heart: Metabolic and behavioral drivers are modifiable targets 

Metabolic kidney illness confirmed essentially the most alarming trajectory. Sort 2 diabetic kidney illness recorded the biggest enhance in age-standardized mortality amongst all CKD subtypes (+36.93%), and hypertensive kidney illness prevalence successfully doubled. Metabolic threat factors-high fasting plasma glucose, excessive systolic blood strain, and excessive physique mass index-were the dominant attributable dangers throughout all ages, with their mixed affect roughly twice as massive in ladies aged 50 and older as in youthful ladies. Amongst reproductive-age ladies, the attributable burden linked to excessive physique mass index greater than doubled (+112.17%) and that linked to sugar-sweetened drinks rose by 132.97%, pointing to a widening metabolic vulnerability that begins effectively earlier than midlife. 

4. Demographic drivers: Inhabitants progress and ageing speed up the CKD burden in ladies 

In 2021, heart problems attributable to impaired kidney perform in ladies accounted for 18.19 million DALYs-about 46.70% of the whole burden of kidney dysfunction on this inhabitants. Ischemic coronary heart illness alone contributed roughly 60% of this cardiovascular burden, adopted by cerebral hemorrhage and ischemic stroke. Geographical disparities had been pronounced: ladies in low and low-middle sociodemographic areas carried the very best CKD burden, whereas high-income North America confirmed the quickest progress in CKD-related mortality. Decomposition evaluation revealed that inhabitants progress (58.63%) and inhabitants ageing (26.64%) had been the principal engines driving the worldwide rise in CKD-related DALYs.

5. Conclusion 

“Girls face a converging metabolic–renal–cardiac menace that unfolds throughout the life course,” concludes Prof. Solar. “Integrating kidney screening into preconception and antenatal care, tightening management of weight problems, glucose, and blood strain from younger maturity, and increasing entry to kidney-protective therapies reminiscent of sodium–glucose cotransporter 2 inhibitors in low-resource settings shall be important to bend this curve.” The authors name for sex-specific CKD registries, multidisciplinary cardio-kidney-metabolic clinics, and coverage funding in ladies’s kidney well being as pressing subsequent steps.
