Urea Level, Urine Crystallization, and Related Factors in Tahu Workers

Abstract

Background & Objective: The process of making tahu which generates a heat source, causes workers to affect the crystallization level of urine and the level of urea of ​​the worker. This study was to analyze the factors associated with urinary crystallization and urea levels. Materials and methods: This study is an analytical study with a cross-sectional design. The independent variables in this study were age, gender, water consumption, clothing use, physical activity, heat stress, urine pH, BMI, and dehydration status. The dependent variable is urine crystallization and urea levels—the analysis used in univariate and bivariate analyses. Results: Based on the chi-square test, it was found that age, years of service, heat stress, dehydration level, BMI, and water consumption were related to urine crystallization levels. Meanwhile, age, years of service, urine pH, heat pressure, dehydration level, BMI, and water consumption were related to urea levels. Conclusion: Of the ten types of variables studied, six variables had a statistically significant relationship with urine crystallization, namely age, years of service, heat stress, level of dehydration, BMI, and water consumption. Meanwhile, age, years of service, urine pH, heat pressure, dehydration level, BMI, and water consumption, seven variables related to urea levels. However, the water consumption pattern of respondents with abnormal heat pressure in the work area should get more attention because the measurement results of water consumption are less.
