What is an age-adjusted rate?

What is an age-adjusted rate?

Rates that are based on the same age distribution can be compared to each other without the presence of confounding by age. Adjustment is accomplished by first multiplying the age-specific rates of disease by age-specific weights. The weighted rates are then summed across the age groups to give the age-adjusted rate.

How do you calculate age-adjusted?

Age-adjusted rates were calculated by dividing the expected number of deaths by the population (standard) and multiplying by 1,000.

What is an adjusted rate?

An adjusted rate is an artificially created figure that enables comparison across time and space. It should only be compared with another adjusted rate that was computed using the same “standard” population. However, it does provide a single figure which can be easily used and adapted for comparative analysis.

What does adjusted mortality rate mean?

Definition: AGE-ADJUSTED DEATH RATE is a death rate that controls for the effects of differences in population age distributions. It weights the age-specific rates observed in a population of interest by the proportion of each age group in a standard population (Lilienfeld & Stolley, 1994).

Why is age-adjusted rates important?

An age-adjusted rate is the best summary statistic for comparing the impact of dis- eases like heart disease, cancer, stroke and diabetes that are heavily influenced by age. Age-adjusted rates are useful for identify- ing differences that are due to environmen- tal or behavioral risk factors instead of age.

How do you calculate age adjustment?

Adjusted age is the developmental age of the baby based on his due date. To calculate adjusted age, you take your premature baby’s chronological age (for example, 20 weeks) and subtract the number of weeks premature the baby was (born 6 weeks early).

What does adjusted age mean?

Definition of Adjusted Age. Adjusted Age means attained age at last birthday adjusted as follows: Adjusted Age means an adjustment that is made for premature birth (gestation < 37 weeks) used to determine developmental status until the child is 18 months old.

What does adjusted rate mean?

Adjustable Rate. An interest rate on a loan or convertible security that changes periodically. For example, an adjustable rate mortgage has a certain interest rate that changes with varying frequency. The frequency of the change is called the adjustment rate.

What does age adjusted death rate mean?

Age Adjusted Death Rate. A death rate that controls for the effects of differences in population age distributions, a value which indicates the risk of dying relative to a standard population. The AADR is thought to be more efficient than crude death rates for comparing mortality of population groups with different age structures.
