Comparison of sensory-neural hearing between firefighters and office workers

Rescuer systems personnel such as firefighters have importance in health assessment. Because of stressful situation, chemicals, metals, gases and noises, they need many physical and paraclinic examination such as audiometry in periodic examinations. Comparison of sensory - neural hearing between firefighters and office workers. A cross-sectional study had been done on firefighters and office workers with use of the clinical - health issues. Data had been analyzed in SPSS 11.5 by T-test and Chi-2 with significance level of P<0.05. Mean of hearing threshold in firefighters' right ear in 4000, 6000, 8000 Hz was 16.05 +/- 8.66 dB and in office workers was 15.20 +/- 6.47 dB with t=0.786 and P=0.433 had no significant difference, this mean in firefighters' left ear was 16.17 +/- 8.12 dB and in office workers was 15.52 +/- 6.67 dB with t=0.617 and P=0.538 had no significant difference too. Mean of hearing threshold in firefighters' right ear in age 40 or less than it in 4000 Hz was 20.51 +/- 10.11 dB and in office workers was 17.50 +/- 5.28 dB with t=2.153 and P=0.033 had significant difference. Mean of hearing threshold in firefighters in all frequencies was normal, except 4000 frequency. It showed the early effect of occupational exposure on hearing

Cardiovascular disorders risk factors in different industries of Iran

Disorders of cardiovascular system can cause disability or death, screening is necessary specially in workers who maybe had risk factors. Hypertension, hyperlipidemia, obesity, smoking, genetic, exposure to chemicals, fumes, solvents, coldness are non occupational and occupational risk factors. Objective was comparison of cardiovascular disorders risk factors between workers in different industries of Iran. In a cross-sectional study, workers of automobile, food industries and light works had been selected and cardiovascular disorders risk factors had been gathered then data analyzed in SPSS with one-way ANOVA, Chi-2 and multi nominal logistic regression with P < 0.05. 875 workers had been participated in the study, all of the cardiovascular disorders risk factors were in the normal range. Mean of high density lipoprotein [HDL] in food industry workers was 63.83 +/- 17.42 mg/dl and it was protective, but in workers who work in automobile industry was 38.97 +/- 11.08 mg/dl and the lowest, Also hypertension and hypertriglyceridemia were more prominent in this industry and after regression with P < 0.05, the differences were significant. Screening of cardiovascular disorders risk factors were important and helpful in industries specially automobile industry, that might be preventive method for these disorders in the future

Is being a health-care worker a risk factor for women's reproductive system?

Occupational exposures to workplace hazards in health-care workers can affect on their health including the reproductive system. Some exposures cause reproductive system disorders. Objective of this study was to compare reproductive system disorders between hospital personnel who work in clinical and administrative setting. This is a historical cohort study on clinical and administrative workers of hospitals. The study tool was flexible interview and questionnaire. Pregnant personnel had been followed until the end of pregnancy. Frequency of reproductive disorders was compared between two groups. Data were analyzed with SPSS 16, t-test, and X[2] were calculated considering P < 0.05 as significant level. Odds ratio had been calculated with a confidence interval 95%. Frequency of menses disorders in clinical personnel especially, personnel of emergency departments were the highest and showed a significant difference between two groups [P = 0.042]. The odds ratio for menses disorders in clinical personnel was 1.362 [1.008-1.84] and in administrative personnel was 0.653 [0.368-1.159]. Clinical personnel are at higher risk for menses disorders compared with administrative personnel. Assessing the health of these personnel may help to improve future generation's health

[Assessment of relationship between blood pressure and cold exposure in workers of dairy and food industry factories in Mashhad]

Cardiovascular diseases and cerebrovascular accidents are the more frequency causes of mortality in the world, we recognized common risk factors but in recent years some work environment exposures such as cold exposure are maybe other risk factors. The aim of this study is the assessment of Blood pressure and body temperature of workers with cold exposure and without this. With a cross -sectional study on 365 workers of dairy and food Industry factories in Mashhad in 2008-2009 by measurement of Blood pressure and body temperature and filling the checklist we performed this study, data has been analyzed with SPSS 11. 5, t-test, regression analysis with P < 0.05. Mean of systolic blood pressure in exposure and none exposure groups are 119. 34, 118. 06 mmHg with P = 0.196, mean of diastolic blood pressure in two groups are 78.66, 77. 19 mmHg with P = 0.03 and mean of body temperature are 36.99 and 37°C with P = 0.079, the mean difference of HDL cholesterol and salt consumption between two groups with P = 0.000 has been significant Mean of blood pressure and body temperature are normal with regression analysis we found that cold exposure might be had some effect on diastolic blood pressure
