Answer 1

1 and 2 ) The incidence rate is the number of new cases per population at risk in a given time period.

Incidence rate = total number of new cases of a specific disease during a given time period / total population at risk during the same time period × 1000

Males :

# For age <35 years :-

Number of new cases of diabetes is 2

Population of males below 35years is 10000

= 2/ 10000 × 1000

= 1/5

= 0.2 %

# For age between 35- 54years :-

Number of new cases males having diabetes is 10

Population of males between 35- 54 years is 5000

= 10/5000×1000

= 2%

# For age group 55-64 years

Number of new cases males having diabetes is 7

Population of males between 55-64 years is 2200

= 7/2200×1000

= 35/11 = 3.1%

# For age 65 years :-

Number of new cases males having diabetes is 53

Population of males above 65years is 4780

= 53/4780× 1000

= 11%

Females :-

# For age below 35years :-

Number of new cases males having diabetes is 10

Population of males below 35 years is 11000

= 10/ 11000× 1000

= 0.9%

# For age between 35- 54 years :-

Number of new cases females having diabetes is 5

Population of females between 35- 54 years is 6000

= 5/6000× 1000

= 0.8%

# For age between 55-64:-

Number of new cases females having diabetes is 6

Population of females between 55-64 years is 2400

= 6/2400 × 1000

= 2.5%

# For age above 65 years :-

Number of new cases females having diabetes is 50

Population of females above 65years is 5290

= 50/ 5290 × 1000

= 9.4% .

3 ) Period prevalence is the number of persons with a specific disease at one point in time divided by total number of persons in the population.

Males :

# For age <35 years :-

Number of new cases of diabetes is 2

Population of males below 35years is 10000

= 2/ 10000

# For age between 35- 54years :-

Number of new cases males having diabetes is 10

Population of males between 35- 54 years is 5000

= 10/5000

# For age group 55-64 years

Number of new cases males having diabetes is 7

Population of males between 55-64 years is 2200

= 7/2200

# For age 65 years :-

Number of new cases males having diabetes is 53

Population of males above 65years is 4780

= 53/4780

Females :-

# For age below 35years :-

Number of new cases males having diabetes is 10

Population of males below 35 years is 11000

= 10/ 11000

# For age between 35- 54 years :-

Number of new cases females having diabetes is 5

Population of females between 35- 54 years is 6000

= 5/6000

# For age between 55-64:-

Number of new cases females having diabetes is 6

Population of females between 55-64 years is 2400

= 6/2400

# For age above 65 years :-

Number of new cases females having diabetes is 50

Population of females above 65years is 5290

= 50/ 5290
