Environmental factors and chronic kidney disease: a case-control study.

Area of Science:

• Environmental Health
• Nephrology
• Epidemiology

Background:

• Chronic kidney disease (CKD) is a global health concern characterized by declining glomerular filtration rate (GFR).
• Environmental factors are increasingly recognized as potential contributors to CKD development.
• Understanding these associations is crucial for public health interventions.

Purpose of the Study:

• To investigate the association between various environmental factors and the risk of CKD in the Iranian population.
• To identify specific environmental exposures linked to higher CKD incidence.
• To provide evidence for targeted prevention strategies.

Main Methods:

• A hospital-based case-control study involving 700 participants (350 CKD cases, 350 controls).
• Participants were matched for age and gender frequency.
• Multiple logistic regression analysis was used to assess the association between environmental factors and CKD risk, calculating odds ratios (ORs) and 95% confidence intervals (CIs).

Main Results:

• Proximity to mines was significantly associated with increased CKD risk (OR=3.98, 95%CI: 2.20-7.21).
• Proximity to mobile antennas showed a significant association with higher CKD risk (OR=2.20, 95%CI: 1.24-3.89).
• Exposure to chemicals was strongly linked to increased CKD risk (OR=4.40, 95%CI: 2.27-8.53).

Conclusions:

• Environmental factors, including proximity to mines, mobile antennas, and chemical exposure, are significantly associated with an elevated risk of CKD.
• These findings highlight the importance of environmental exposures in the etiology of CKD.
• Recommendations for high-heat work environments include hydration, reduced work hours, and proper ventilation to protect kidney health.
