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

ABSTRACT

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
