Climate change and chronic kidney disease (CKD) among outdoor workers: a systematic review

Global warming was positively related to chronic kidney disease (CKD) among outdoor workers. Based on the present systematic review, we gathered the risk factors (individual, environmental, and occupational) for climate change-induced CKD among outdoor workers up to 2023. There has been a rapid increase of CKD in tropical and subtropical countries with low and middle income. Among the risk factors air temperature, diabetes, hypertension, physically demanding job tasks, age, sex, dehydration, working and living in a hot environment, and body mass index (BMI) were the main contributors to CKD-related. Although the high hot-wet and hot-dry climate conditions related to CKD were high, this trend increased in developing countries. Climate change will adversely impact global kidney health over the century through its effects on temperature and the risk of endemic infections. Outdoor workers may face an elevated risk of CKD, with the male population being more vulnerable. Implementing preventive strategies (cooling techniques, acclimation, work/rest cycles, and appropriate clothing) against heat stress due to global warming is crucial.
