ABSTRACT
BACKGROUND: Earth's climate changes are progressing at an alarming rate. One of the most severe effects of climate change is extreme heat. This study aimed to assess knowledge and adaptation behavior to heat-related illness (HRI) among solid waste disposal workers in the 10th of Ramadan City, Egypt, and to study the predictors for their knowledge and adaptation behavior. METHODS: An exploratory cross-sectional study was conducted on 220 solid waste disposal workers. A structured interview questionnaire was used to assess the studied workers' sociodemographic and occupational characteristics, heat exposure risk, and their knowledge, and adaptation behavior. RESULTS: The results showed that 40% and 30% of participants had adequate levels of total knowledge and adaptation behavior, respectively. There was a statistically significant relationship between workers' knowledge and both age and education. There was a statistically significant relationship between workers' adaptation behavior and age, duration of employment, working hours, and education. A binary logistic regression for significant predictors of knowledge and adaptation behavior showed that age and education were the most significant predictors. CONCLUSION: Solid waste disposal workers were at high risk of HRI due to their low levels of knowledge and adaptation behavior regarding HRI. Educational health programs that guide workers to follow healthy behaviors and prevent HRI are recommended.
ABSTRACT
BACKGROUND: Ionizing radiation is well known to cause oxidative stress which is responsible for various health hazards. Controlling healthcare workers' exposure and raising attention toward continuous monitoring is the first step for improving both the health of healthcare workers and the quality of patient care, thus decreasing both human and economic costs. OBJECTIVES: To assess oxidative stress by measuring the level of lipid peroxidation, antioxidants, and measure complete blood count (CBC) among healthcare workers exposed to ionizing radiation. METHODS: A cross-sectional study conducted at the diagnostic radiology department on 31 healthcare workers exposed to ionizing radiation and a non-exposed group of 31 healthcare workers from outpatient clinics. Malondialdehyde (MDA), superoxide dismutase (SOD), and CBC were measured among both groups. RESULTS: MDA was significantly higher among the exposed group, while the level of SOD was significantly lower. Red blood cells and hemoglobin were significantly lower among the exposed group. The most significant predictor of oxidative stress was the duration of work. CONCLUSION: Ionizing radiation exposure induce oxidative stress which has an important role in radiation-related health effects. Anemia was the most common hematological health hazards among the exposed group.
