Abstract
Introduction: Obesity and overweight are major global health challenges. One of the bad effects of noise that has been recently expressed is the effect of noise on obesity. This study aimed to investigate the effect of high-frequency noise exposure on obesity, food intake, and abdominal visceral fat in adult male guinea pigs.
Material and Methods: The animals in this study were 24 adult male guinea pigs randomly divided into 3 groups (control and two case groups). Each case group was separately exposed to high- frequency white noise with sound pressure levels in 65 dB and 85 dB for 5 days per week in 30 days. The food intake was measured daily. The weight of animals was measured at the start and on days 6, 12, 18, 24, and at the end of exposure period. The abdominal visceral fat was extracted and weighted at the end of the study period. The data were assessed using SPSS V.22 software.
Results: ANOVA analysis showed that exposure to high-frequency noise at 65dB and 85dB had a significant effect on weight gain, food intake, and abdominal visceral fat weight (P-value< 0.05) which in the group exposed to the noise with 65 dB was more than other groups.
Conclusion: Based on this study, exposure to high-frequency noise may be an effective factor in obesity and increasing abdominal visceral fat. Further studies are needed to investigate the mechanism affecting weight status following noise exposure.

Abstract
Introduction: Heat stress is a common environmental risk factor for many occupations, which can lead to increased fatigue during cognitive tasks. Fatigue is a multifactorial phenomenon that is affected by various environmental, physiological, and psychological factors, and can affect biomechanical, physiological, and psychological components. This study focuses on the impact of environmental, individual, and physiological factors, and burnout on general fatigue.
Material and Methods: This descriptive-analytical study was conducted among 189 employees of the Iran Oil Company at both indoor and outdoor workstations. Heat stress was measured using the (WBGT) index, and thermal strain risk was evaluated. Variables such as skin temperature, ear temperature, blood pressure, and heart rate were also monitored. To assess general fatigue and occupational burnout, (MFI) and the Maslach Burnout Inventory were completed by the employees.
Results: The results revealed that 79.9% of the employees were exposed to heat stress, with repair workers experiencing the highest levels of emotional exhaustion (23/38), depersonalization (15/34), general fatigue (10/00), and physical fatigue (9/05). Statistically significant relationships were found between heat stress and fatigue and decreased motivation, between all components of burnout and general fatigue, and between core temperature, blood pressure, and general fatigue (p<0.05). Notably, demographic factors such as marital status, smoking status, and education level did not significantly influence fatigue scores.
Conclusion: Fatigue is strongly associated with heat stress, physiological variables such as body temperature and blood pressure, burnout, personal habits such as sleep duration and exercise, and the type of job. These findings suggest that in hot work environments, monitoring physiological variables and environmental factors can help identify and address fatigue issues.

Abstract
Introduction: Nurses play a crucial role in hospital settings, often undertaking demanding tasks that exceed their physical and cognitive capacities. The Structured Multidisciplinary Work Evaluation Tool (SMET) is an instrument for evaluating and identifying risks in workplace environments. The objective of this study was to assess the psychometric properties of the Persian (Farsi) version of the SMET.
Material and Methods: In this cross-sectional study, the face and content validity of the questionnaire were evaluated both qualitatively and quantitatively by a panel of 13 experts. Quantitative content validity was performed using the Content Validity Ratio (CVR) and Content Validity Index (CVI). Reliability was measured using Cronbach’s alpha and Intraclass Correlation Coefficient (ICC).
Results: The face validity assessment revealed that questions 3, 4, 6, 23, and 24 required clarification. The CVI for all items was calculated to be above 0.79. However, several questions had a CVR below 0.54, indicating that specialists considered some questions unnecessary or repetitive. Consequently, these questions were either removed or merged with similar items based on the scores and subsequent reviews. Cronbach’s alpha and ICC values for the entire questionnaire and its dimensions were above 0.7, indicating acceptable to strong reliability.
Conclusion: The Persian version of the SMET questionnaire demonstrated acceptable psychometric properties for comprehensive multifactorial evaluation of healthcare workplaces.
