38. Low Back Pain

39. Obese patients were more likely to have radicular pain and neurologic signs. Obesity was a significant, independent determinant of chronicity in a prospective cohort study in workers claiming compensation for lower back pain. In morbidly obese subjects with lower back pain undergoing bariatric surgery, weight loss significantly improved the degree of functional disability, and resulted in less frequent lower back pain and the use of reduced doses of medications

41. Tendinopathy Common musculoskeletal diseases Obesity measured in terms of BMI (BMI ≥ 30 kg/m2) and tendon diseases, with odds ratios ranging from 1.9 (95% CI: 1.1–2.2) to 5.6 (1.9–16.6) Mechanical factor –Stronger association between lower limb tendinopathies and obesity, compared to upper limbs Metabolic factor –Failed healing response Franceschi, F., et al. Int J Endocrinol 2014

42. Achilles Tendinopathy Overloading Long stranding Failed healing response –Alteration of blood flow Metabolic risk factors –Obesity –Diabetes –Hypertension –Use steroid

43. Achilles Tendinopathy

44. Rotator Cuff Tendinopathy Wendelboe et al. in 2004, 311 participants –Individuals with a BMI ≥35.0 had an increased risk to require rotator cuff repair Odd ratio: 3.1 (CI 1.3–7.6) for males Odd ratio: 3.5 (1.8–6.9) for females Titchener et al. in 2013, 5000 patients –Overweight body mass index of 25.1 to 30 (OR = 1.15) was significantly associated with rotator cuff disease –Body mass index greater than 30 was not found to be associated with rotator cuff disease

45. Rotator Cuff Tendinopathy Rechardt et al. in 2010, 6237 patients –Smoking, waist circumference, and waist-to-hip ratio were related to an increased prevalence of shoulder pain in both men and women. –Metabolic syndrome, type 2 diabetes mellitus, and carotid intima-media thickness were associated with shoulder pain in men, –Increased waist circumference and type 1 diabetes mellitus were associated with chronic rotator cuff tendinitis in men.

50. Elbow Tendinopathy Mechanical overloading Abnormal microvascular responses Titchener et al. in 2013, 4998 participants –Obesity is not associated with epicondylitis

51. Elbow Tendinopathy Descatha et al. in 2013, 699 patients –Subjects with BMI >30 kg/m2 had higher incidence rates for the disease (OR: 2.4, CI: 1.2–4.8) –No significant association was instead found for medial epicondylitis Shiri et al. in 2006 4783 patients –Medial epicondylitis in women and both waist circumference >100 cm (OR: 2.7CI: 1.2–6.0) and BMI >30 kg/m2 (OR: 1.9CI: 1.0–2.7), –No increased risk as regards lateral epicondylitis.

52. Plantar Fasciitis Loss of the transverse foot arch Higher vertical forces under the heel during gait Effect of an increased weight on musculoskeletal disorders of the lower district (feet and ankles), which are known to be caused by overuse and stress, which are factors made worse by weight

53. Entrapment Neuropathy Meralgia paresthetica –Neuropathy of the lateral femoral cutaneous nerve –MP with BMI odds ratio (OR) 1.2 Carpal tunnel syndrome –Obesity was a significant risk factor associated with carpal tunnel syndrome (OR=2.06).

55. Osteoporosis 10 kg increase in body weight is associated with approximately a 1% increase in BMD the effect of weight on BMD appears to be stronger in women than in men Mechanism –Adipose tissue the major site of conversion of androgens to estrogen in both elderly men and women –increased mechanical load

56. Gout Obesity is a well-known modifiable risk factor in the pathogenesis of gout and serum uric acid is positively associated with BMI The size of the visceral fat area is the strongest contributor to elevated serum uric acid concentration, decreased uric acid clearance and increased urinary uric acid/creatinine ratio
