Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body.

Factors Influencing Duration

Length of disability will be influenced by the type of anemia, rapidity of onset, severity of symptoms, the individual's age, health status, alcohol or illicit substance use, method of treatment, and individual's compliance with and response to treatment.

Prognosis

In any anemia, the cause of the anemia, its severity, and rapidity of its development determine the outcome. The age of the patient and the presence of comorbid conditions such as heart, lung, kidney, or liver disease may also significantly influence outcome.

Outcome of anemia due to blood loss depends on the source of the bleeding, severity of the loss, and response to treatment. If the source of bleeding is identified and corrected, acute anemia due to massive blood loss can be successfully treated with blood transfusion. Chronic anemia due to a small but ongoing blood loss, such as in gastrointestinal bleeding, responds to correction of the bleeding without the need for transfusion if the source of bleeding is identified before blood loss is significant.

Anemia caused by dietary deficiencies usually can be corrected by replacement therapy, and improvement may be seen within weeks or months. Neuropsychiatric symptoms caused by pernicious anemia may take up to a year or more to show improvement. The symptoms may not resolve completely, but with ongoing treatment they typically do not progress.

Individuals with severe lifelong, hereditary anemias (e.g., sickle cell anemia, thalassemia) have a shortened life expectancy. Without a bone marrow transplant, severe forms of these anemias often result in death in the second or third decade of life (Conrad).
