Question

In 2000, there were 3,600 deaths due to lung diseases in miners aged 20 to 64 years. The expected number of deaths in this occupational group, based on age-specific deaths rates from lung diseases in all males aged 20 to 64 years, was 1,200 during 2000. What is the standardized mortality ratio (SMR) for lung disease in miners? Interpret this ratio.

Explanation / Answer

Given that observed Death= 3600
Expected Death= 1200
Then standardized mortality ratio is given by formula
SMR = Observed deaths/Expected Death
SMR = 3600/1200 = 3
value of SMR is more which means actual deaths are 3 times than expected deaths.
