A recent study conducted in Japan has shed light on the significant impact of participation rates in specific health checkups (SHCs) on the incidence of treated end-stage kidney disease (ESKD) and the prevalence of chronic kidney disease (CKD) at the prefecture level.
The findings, published in the journal Clinical and Experimental Nephrology, emphasize the importance of increasing SHC participation rates across populations and encouraging individuals to undergo regular health checkups.
Regional Disparities in Kidney Disease
Japan is characterized by substantial regional disparities in the incidence and prevalence rates of treated ESKD, despite having a uniform healthcare and insurance system and relatively low ethnic and racial diversity.
These disparities prompted researchers to investigate the role of SHC participation rates in shaping the landscape of kidney disease.
SHCs are annual health screening programs introduced by Japan’s Ministry of Health, Labor, and Welfare since 2008.
They aim to identify individuals at risk for metabolic syndrome and offer specific health guidance to mitigate these risks.
The Study’s Methodology
To explore the relationship between SHC participation rates and kidney disease, researchers collected data from five nationwide open sources. Their analysis revealed compelling insights:
Direct Negative Effects: SHC participation rates had significant direct negative effects on the standardized incidence rates (SIRs) of treated ESKD and the prevalence of CKD at the prefecture level.
Indirect Effects: Through SHC participation rates, the ratio of nephrology specialists also had a significant indirect negative effect on prefecture-specific SIRs.
This suggests that prefectures with a higher ratio of nephrology specialists tended to have lower SIRs for treated ESKD.
Model Accuracy: The structural equation modeling model explained 14% of the variance in prefecture-specific SIRs. This indicates that SHC participation rates can help account for regional variations in ESKD incidence.
Implications and Encouragement for Health Checkups
These findings align with earlier research, emphasizing the importance of regular health checkups, especially in the context of kidney health.
The study underscores the significance of improving SHC participation rates on a population-wide scale.
Encouraging individuals to undergo health checkups, particularly those at higher risk or in older age groups, can be instrumental in reducing the burden of kidney diseases.
Conclusion
The Japanese study offers valuable insights into the strong connection between SHC participation rates and the incidence of kidney diseases.
By highlighting the impact of health checkups in reducing the prevalence of ESKD and CKD, the research underscores the significance of proactive healthcare measures at both individual and population levels.
Encouraging regular health checkups remains a pivotal strategy in safeguarding kidney health and reducing the regional disparities in kidney disease incidence.
