age-adjusted rate is different from a crude rate in that the incidence rate is modified to take into account how the age distribution of the population of interest varies from a conventionally-used "standard population". It is important that the same standard population be used so that age-adjusted rates can be compared to each other. The U.S. 1970 population has been used as a standard for many years, and the U.S. 2000 population will soon be used as the standard.

age-specific incidence rate is the number of newly diagnosed cases of a disease in a specific age group in a particular population over a specified time period per "x" number of people in that age group. Typically, five-year age groups (0-4, 5-9, 10-14, etc.) are used. The time period is usually one year and the "x" number of people in the specific age group is usually 100,000.

The term "incidence" refers to the number of newly diagnosed cases of a disease occurring in a specific population during a specific time period. The incidence rate is the number of newly diagnosed cases in a specific population during a specific time period per "x" number of people; usually the time period is one year and "x" number of people is 100,000. Such an incidence rate is "crude", is not age adjusted (see #11 below) and therefore cannot be used to compare different populations. See similar questions...

Age adjusted rates are standardized so that the relationship between age and particular causes of death has been statistically eliminated. These rates allow communities with different age distributions to compare causes of death. Age ?adjusted rates should be viewed as relative indexes rather than actual measures of occurrence. 2 See similar questions...

The rates of almost all causes of disease, injury, and death vary by age. Age adjustment is a technique for "removing" the effects of age from crude rates so as to allow meaningful comparisons across populations with different underlying age structures. See similar questions...

AVONEX has a low (5%) incidence of neutralizing antibodies. In the EVIDENCE study, the incidence of neutralizing antibodies was 12 times higher in the Rebif (Interferon beta-1a) treatment group than in the AVONEX treatment group. The clinical significance of neutralizing antibodies is unknown. See similar questions...

There are two ways to adjust the discharge rate. The first is by changing the height of the flow-adjusting ring. This corresponds to the distance between the bottom edge of the cylinder and the flat surface in the example above. This is considered a "rough" adjustment and generally results in a 3:1 turndown. The other way to change the capacity is by changing the shaft rotational speed. By using a variable frequency drive an additional 5 to 10:1 ratio can be obtain. See similar questions...

Yes, on a camera by camera basis. Some systems have what is known as a "global rate", meaning all cameras record at the same rate or speed of frame capture. See similar questions...

The incidence rates used to make these maps are age-adjusted. That means we produced the rates in a way that lets us compare one county to another, by taking into account the ages of the people in each county. See similar questions...

Yes. The interest rate will not increase (or decrease) more than 3.5% during the term of the loan. In addition, each change frequency (occurring each year or every five years) will not allow more than a 2.5% increase or decrease from the previous rate. See similar questions...

Personally, I get checked by my chiropractor at least once per week. I am adjusted as needed (usually every week). Now mind you, I have been a regular chiropractic patient since 1994, and still need to be adjusted weekly due to the stresses in my life that cause me to be subluxated that often. I check my wife and children daily. See similar questions...

The Band is tightened by accessing the port with a needle. This is most commonly done in the office. Some surgeons do it at the hospital under x-ray guidance, but this is generally not necessary, and makes the procedure much more expensive. For patients with very thick abdominal walls, it may be more difficult to find the port. In our office we have an ultrasound machine which makes it possible to access most ports without need for x-ray. See similar questions...

Texas Cancer Information expects to add incidence data in the fall of 2007. There is currently limited incidence and survival data available in the on-line publication of Texas Cancer Facts & Figures 2004 , a publication made possible through the collaborative efforts of the American Cancer Society, Texas Division, Inc.

Studies suggest the prevalence is somewhere between 1 in 200 - 500. In recent years there has been a large increase in the number of children diagnosed with ASD, particularly those in the high functioning category. This is probably due to a broadening of the criteria for diagnosis, and better diagnostics methods enabling detection at a very young age. See similar questions...

The student must be 65 or older prior to the start of the semester to qualify for senior citizen rates. See similar questions...

Most health outcomes and behaviors are related to age. Epidemiologists use age adjustment to compare the attributes of two or more groups whose age distributions may be different. Take the following examples: The prevalence of smoking, individuals' cholesterol levels, and death rate all increase with age. In addition, persons in various groups sampled in CHS may have different age distributions than others. For example, females interviewed in the CHS are slightly older than males.

A: Corrected or adjusted chronological age must be used at the point of eligibility if the child is being considered for First Steps eligibility based on developmental delay. It should also be used when interpreting Developmental Assessment for IFSP planning. It is calculated by deducting one-half the prematurity (based on 37 weeks gestation) from the child's chronological age. It should be assigned for a period of up to 12 months or longer if recommended by the child's physician. See similar questions...
