O-368 the Prevalence of Chronic Kidney Disease Among Indonesian Workers Exposed to Excessive Heat: Survey From Secondary Data at an Industry in West Java Indonesia

Introduction Dialysis for end-stage chronic kidney disease (CKD) represents the second highest expenditure of Indonesian Health Insurance. This study aims to investigate the prevalence of CKD among workers exposed to excessive heat and explore the associated risk factors. Method This study was conducted at an industry in West Java, between March and June 2023. Secondary data was obtained from the annual Medical Check-Up 2022-2023 data and heat measurements data in 2017. CKD was defined as having a creatinine value >1.2 in two consecutive years. The data analysis operated Chi-square and logistic regression. Results Subjects eligible for this study totaled 675, of which 99.7% were male and 49% were >40 years old. Most workers (96.1%) had been exposed to temperatures exceeding 28°C, 47% were classified as obese, 16.7% had hypertension, 5.5% had diabetes mellitus, and 63.9% has worked for more than 5 years. The prevalence of CKD was 5.5%. The relative risk (RR) for workers older than 40 years to develop CKD was 2.4 (95% CI 1.11-5.11), while the RR for obesity was 2.3 (95% CI 1.07-5.08), and the RR for hypertension was 3.2 (95% CI 1.58-6.65). All workers diagnosed with CKD had been exposed to temperatures exceeding 28°C and worked for more than five years. Discussion The CKD prevalence found in this study was higher than Indonesian population. The association with excessive temperature could not be discovered because almost all workers were exposed to it. Conclusion Further research is required to understand the impact of heat on CKD among workers.
