Correlation of Pain, Obesity and Fertility Potential.

27. maj 2015 opdateret af: Northern Orthopaedic Division, Denmark

Obesity, Pain and Fertility: is There Any Association?

The overall aim of the study is to investigate if patients with musculoskeletal chronic pain have reduced semen quality in comparison with age matched healthy controls. Secondly, the aim is to investigate whether overweight with or without chronic pain are related to reduced semen quality. We will investigate semen quality in obese chronic pain patients, normal weight chronic pain patients and in obese and normal weight healthy controls.

Detaljeret beskrivelse

Obesity is associated with several disorders including chronic musculoskeletal pain. For example obesity has been implicated in the development or progression of low back pain and knee osteoarthritis. The mechanism by which obesity causes lumbar back pain is poorly understood, but the contribution of both mechanical and system factors is likely. Direct mechanical stress on the intervertebral discs and adjacent structures are suspected to be mechanisms through which obesity affects the spine, leading to subsequent low back pain. The link between obesity and knee osteoarthritis has also been demonstrated, but potential factors underlying the association of obesity with knee osteoarthritis has not entirely been elucidated.

It is a well-known fact that obesity leads to an excess load on the joint, increased cartilage turnover, increased collagen type 2 degradation products and increased risk of degenerative meniscal lesions. Although all of these factors have been proposed to lead to knee osteoarthritis, no causal relationship has been demonstrated.

Pain
Tidsramme: 6 months
The patients will be tested for their pain in terms of intensity and quality. Intensity will be rated on a visual analogue scale (VAS 0-10) for ongoing pain. Pressure pain will be measured by application of a handheld pressure algometer. A validated Danish version of short form McGill Pain Questionnaire will be given to evaluate the quality of pain. In addition, distribution of pain will be mapped by drawing on a body chart.
