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. 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.

Overview

Image Description:
Prostatitis - A profile of the male trunk and lower abdomen reveals the position of a normal prostate gland within the abdomen behind the scrotum, the urethra leading into the penis, and the bladder just above the reproductive organs. The prostate gland is shown to be enlarged and inflamed.

Prostatitis refers to inflammation of a secretory gland (prostate) in the male reproductive system. The three types of prostatitis are acute bacterial, chronic bacterial, and nonbacterial.

Acute bacterial prostatitis is an acute infection of the prostate caused by certain types of bacteria (gram-negative aerobes). This condition may be associated with inflammation of the urinary bladder (cystitis) and an inability to completely empty the urinary bladder (acute urinary retention).

Chronic bacterial prostatitis is also caused by gram-negative aerobes and, possibly, gram-positive bacteria. The inflammatory reaction in chronic prostatitis is less intense than in acute prostatitis, and the individual may have less intense symptoms.

In both acute and chronic prostatitis, bacterial infection of the prostate may descend from the tube (urethra) by which urine is excreted from the urinary bladder, or it can be caused by a sexually transmitted disease (gonorrhea, chlamydia) that ascends the urethra. Bacterial infection may also occur following anal intercourse, or it can result from bacteria that have spread through the bloodstream.

Nonbacterial prostatitis has signs and symptoms similar to those of bacterial prostatitis, except that urinary tract infections (UTI) almost never occur in the nonbacterial form. Nonbacterial prostatitis may result from physical (neuromuscular) injury or an abnormal response of the immune system (autoimmune disease). It is unclear at this time whether either of these factors actually causes nonbacterial prostatitis; the origin of this condition remains a mystery. However, the vast majority (90% to 95%) of prostatitis is nonbacterial (Ahuja).

Incidence and Prevalence: In the US, symptoms of prostatitis are the most common urological problem in males younger than 50, and account for more than 1 million physician visits each year (Henderson). The prevalence of prostatitis is about 10% of males between the ages of 20 to 74 (Ahuja). The international incidence for prostatitis is similar to the US. However, in underdeveloped countries there is increased incidence of bacterial prostatitis in conjunction with other disseminated disease; there is also increased incidence in regions where there are higher rates of prostitution and sexually transmitted diseases (Henderson).
