Some studies indicate that diagnosable dissociation occurs in approximately two to three percent of the general population. Other studies have estimated a prevalence rate of 10% for all dissociative disorders in the general population (e.g., Loewenstein, 1994). Dissociation may exist in either acute or chronic forms. Immediately following severe trauma, the incidence of dissociative phenomena is remarkably high.

Research tends to show that dissociation stems from a combination of environmental and biological factors. The likelihood that a tendency to dissociate is inherited genetically is estimated to be zero (Simeon et al., 2001). Most commonly, repetitive childhood physical and/or sexual abuse and other forms of trauma are associated with the development of dissociative disorders (e.g., Putnam, 1985).

There are four main categories of dissociative disorders as defined in the standard catalogue of psychological diagnoses used by mental health professionals in North America, the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR).

Dissociative disorders are a spectrum of disorders that rely heavily on dissociation as a means of self-protection from extreme emotions. This coping mechanism leads to significant distress or impairment in social, occupational, or other important areas of functioning.

The lead federal agencies working to reduce the burden of mental disorders are the National Institute for Mental Health (NIMH) and the Center for Mental Health Services (CMHS). Both organizations have extensive Web sites that provide substantial information including statistics on mental disorders, reports and fact sheets on specific mental disorders in specific populations, and consensus conference reports on the diagnosis and treatment of mental disorders.

For decades, autism was believed to occur in 4 to 5 per 10,000 children. In 2004, CDC partnered with the American Academy of Pediatrics (AAP) to issue an Autism A.L.A.R.M.[1] At that time, Data from several studies that used the current criteria for diagnosing ASDs (DSM-IV and ICD-10) found prevalence rates for ASDs between 2 and 6 per 1,000 children. Therefore, it was summarized that up to 1 in 166 children (6/1,000) have an ASD.

Arthritis is a common musculoskeletal disorder which affects more than 500 million people worldwide, including one in three Americans. Every year in the United States, musculoskeletal conditions including musculoskeletal disorders and musculoskeletal trauma accounted for more than 150 million visits to physiciansâ?? offices, including:

Prevalence is the representation of the number of patients within a given facility that have pressure ulcers at a specific point in time (usually 24 hours). Prevalence - using the day's census, skin assess all patients. P= number of patients with ulcers The census is the number of patients that need to be assessed; however, the actual number assessed may differ. Patients can refuse to participate, be out of the room or not be available during the study time period.

CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network released data in 2007 that found about 1 in 150 8-year-old children in multiple areas of the United States had an ASD. Since the ADDM sites do not represent a nationally representative sample, the prevalence estimates should not be generalized to every community in the United States. Although accurate for the areas we studied, rates may be higher or lower in other areas.

Amnesia refers to the inability to recall important personal information that is so extensive that it is not due to ordinary forgetfulness. Most of the amnesias typical of dissociative disorders are not of the classic fugue variety, where people travel long distances, and suddenly become alert, disoriented as to where they are and how they got there.

Dissociative effects include distorted perceptions of sight and sound as well as feelings of detachment or separation from the environment and self.

This page actually gets pretty in-depth. From the Diseases & Conditions section of the Mayo Clinic's massive online site, this page goes into: Dawn Myers talks about the possibility that some people develop eating disorders as a method of coping with the trauma of child sexual abuse.

Results from the 2003-2004 National Health and Nutrition Examination Survey (NHANES), using measured heights and weights, indicate that an estimated 66 percent of U.S. adults are either overweight or obese.

IBS affects between 25 and 55 million people in theUnited States and results in 2.5 to 3.5 million yearly visits to physicians. Approximately 20 to 40 percent of all visits to gastroenterologists are due to IBS symptoms. IBS symptoms affects men and women of all ages and of all races. The prevalence of IBS in the general population of Western countries varies from 6 to 22%. IBS affects 14-24% of women and 5-19% of men.

The facility needs to establish a baseline or benchmark prior to making any changes in protocols for prevention and treatment of pressure ulcers (or any condition the facility is trying to manage). The best way to monitor and evaluate the effectiveness of newly implemented protocols is to perform another prevalence/incidence study a year after the

Choose a day to assess all patients in the above units within a 24-hour period. Note: If you are participating in a larger "national" study, then you will have to choose a date within a specified time period. Please contact your KCI Representative if you are unsure about this.

This study will include "Incidence" ? your second observation of patients who developed nosocomial pressure ulcers (facility acquired ulcers).

Families, public agencies, and some private agencies bear the responsibility of paying for costly services involved in educating and treating symptoms associated with ASDs. Accurate reporting of ASD prevalence can help people plan for the resources needed such as therapies, trained teachers, diagnosticians, health care providers, and related service professionals.

In 2003, a detailed, federally supported study was published on the prevalence of autism spectrum conditions among children aged 3 to 10 years in metropolitan Atlanta. Using 1996 data, that study showed the prevalence for autism was 3.4 per 1000, with a male-female ratio of 4 to 1. The study did not show a major increase in autism compared to studies done in the 1980s and early 1990s.

Studies have shown that asthma is more common in African Americans than in Caucasians, but experts are not sure this is related to race. It could be that higher numbers of African Americans live in large urban areas, which is known to be a risk factor because of the higher levels of pollution and other asthma triggers.

In 1999–2000, an estimated 15% of children and adolescents aged 6–19 years were overweight, defined as a body mass index for age and sex at or above the 95th percentile of the CDC growth charts.

More and more women attending antenatal clinics are testing HIV-positive thereby increasing the chances of perinatal transmission. More than 1% of the antenatal mothers in the States of Maharashtra, Tamil Nadu, Andhra Pradesh, Karnataka, Nagaland and Manipur are infected with HIV.

The prevalance of preschool children stuttering is about 2.5%, that is, about 1 in 40 young children now stutter. The incidence is about 5%, or 1 in 20 children stutter at some point in childhood. About 1% of adults stutter. 0.73%, or about one in 135 adults, was the figure found in a recent study. Studies in years past claimed that some countries had higher or lower rates of stuttering, or that some cultures had no stutterers at all.

While there are many different categories of body disorders, the three main types of eating disorders are anorexia nervosa, bulimia nervosa, and binge eating disorder. Anorexics deliberately attempt to lose weight through self-starvation and/or excessive exercising. Despite the constant caloric deprivation and dramatic weight loss, anorexics truly believe they are too fat. Although thousands of women in Canada suffer from anorexia, the disorder comprises only 0.4-1.0% of the population.

this time there is not sufficient evidence to indicate a higher risk for schizophrenia and bipolar disorder in the Jewish community. There are some studies that suggest an increase in affective disorders, including bipolar disorder, in the Jewish community. However, these studies have not been adequately substantiated at this time.
