Evaluation of Heat Stress among Farmers Using Environmenta l and Biological Monitoring: A study in North of Iran

In this  cross sectional s tudy carried out in s pring and s ummer, 79 farmers working  in different  job  pos itions including agriculture, hus bandry and horticulture in north of Iran were participa ted. Evaluation of the heat s tres s was conducted us ing Wet Bulb Glob Temperature (WBGT) index ac...

description In this  cross sectional s tudy carried out in s pring and s ummer, 79 farmers working  in different  job  pos itions including agriculture, hus bandry and horticulture in north of Iran were participa ted. Evaluation of the heat s tres s was conducted us ing Wet Bulb Glob Temperature (WBGT) index according ISO7243 and heat s train evaluation us ing  meas uring  the  individual  phys iological  res pons es  including  aural,  oral  and  mean  s kin  temperatures according ISO 9886. The demographic characteris tics of the s ubjects s uch as age, job experience, BMI and body area were als o gathered  through a ques tionnaire. In general, the s ubjects were in middle ages  (38.44±8.86 yr) and mean and s tandard deviation of years  of expe rience were almos t high (17.49±9.41 yr), too. The s tatis tical analys is was performed  by SPSS 18 s oftware. The  res ults  s howed that the WBGT index values  had  ranging from 24 to  32.6°C in  s ummer  regardles s  of clothing  ins ulation,  metabolic  rate  and  work  res t  regimens .  Of cours e, by correction of thes e parameters the WBGT will accompany with an incens ement. Convers ely, the heat s train monitoring revealed that in no cas e the aural and oral temperatures are higher than the limit allowed. The bes t correlation  coefficient  was obtained  for aural temperature  and WBGT index (r= 0.84, P< 0.001). It  s eems that evaluation of hot and humid environment us ing WBGT index can be as s ociated with an overes timation and encountered our judgment about the environmental condition with a s ignificant error.
