    Chronic low back pain and its association with lumbar vertebrae and intervertebral disc changes in adults. A case control study
    (Wiley, 2018) Karunanayake, A.L.; Pathmeswaran, A.; Wijayaratne, L.S.
    AIM: This study was done to determine the association between chronic low back pain and vertebral fractures, intervertebral disc space (IDS) narrowing, vertebral osteophytes and spondylolisthesis among adults. METHOD: This case control study was done in Sri Lanka. Cases were patients with low back pain and controls were without low back pain. Postero-anterior and lateral radiographs of lumbar sacral spine of both groups were studied. To detect vertebral fractures in fourth and fifth lumbar vertebrae, anterior and posterior heights of vertebrae were measured using a Vernier caliper and antero-posterior ratio (A/P) was calculated. Having an A/P ratio value of < 0.89 was considered as a vertebral fracture. Presence of disc space narrowing, vertebral osteophytes and spondylolisthesis was assessed by two radiologists working independently. Bivariate and logistic regression analysis was done to find associations. RESULTS: There were 140 cases and 140 controls. Mean (SD) age for cases was 51.6 (17) years. Mean (SD) age for controls was 50 (15) years. Females made up 62% of cases and controls. Fifth lumbar vertebral fracture (odds ratio [OR] = 10.2; P = 0.001), fourth lumbar vertebral fracture (OR = 2.5; P = 0.017) and IDS narrowing (OR = 4.15, P = 0.009) had a significant association with low back pain and vertebral osteophytes and spondylolisthesis did not have a significant association with low back pain. CONCLUSION: Only vertebral fractures and IDS narrowing had a significant association with chronic low back pain.

    Epidemiological differences between localized and nonlocalized low back pain
    (Lippincott Williams & Wilkins, 2017) Coggon, D.; Ntani, G.; Walker-Bone, K.; Palmer, K.T.; Felli, V.E.; Harari, R.; Barrero, L.H.; Felknor, S.A.; Gimeno, D.; Cattrell, A.; Vargas-Prada, S.; Bonzini, M.; Solidaki, E.; Merisalu, E.; Habib, R.R.; Sadeghian, F.; Kadir, M.M.; Warnakulasuriya, S.S.; Matsudaira, K.; Nyantumbu, B.; Sim, M.R.; Harcombe, H.; Cox, K.; Sarquis, L.M.; Marziale, M.H.; Harari, F.; Freire, R.; Harari, N.; Monroy, M.V.; Quintana, L.A.; Rojas, M.; Harris, E.C.; Serra, C.; Martinez, J.M.; Delclos, G.; Benavides, F.G.; Carugno, M.; Ferrario, M.M.; Pesatori, A.C.; Chatzi, L.; Bitsios, P.; Kogevinas, M.; Oha, K.; Freimann, T.; Sadeghian, A.; Peiris-John, R.J.; Sathiakumar, N.; Wickremasinghe, A.R.; Yoshimura, N.; Kelsall, H.L.; Hoe, V.C.; Urquhart, D.M.; Derrett, S.; McBride, D.; Herbison, P.; Gray, A.; Vega, E.J.
    STUDY DESIGN: Cross-sectional survey with longitudinal follow-up OBJECTIVES.: To test the hypothesis that pain which is localised to the low back differs epidemiologically from that which occurs simultaneously or close in time to pain at other anatomical sites SUMMARY OF BACKGROUND DATA.: Low back pain (LBP) often occurs in combination with other regional pain, with which it shares similar psychological and psychosocial risk factors. However, few previous epidemiological studies of LBP have distinguished pain that is confined to the low back from that which occurs as part of a wider distribution of pain. METHODS: We analysed data from CUPID, a cohort study that used baseline and follow-up questionnaires to collect information about musculoskeletal pain, associated disability and potential risk factors, in 47 occupational groups (office workers, nurses and others) from 18 countries. RESULTS: Among 12,197 subjects at baseline, 609 (4.9%) reported localised LBP in the past month, and 3,820 (31.3%) non-localised LBP. Non-localised LBP was more frequently associated with sciatica in the past month (48.1% vs. 30.0% of cases), occurred on more days in the past month and past year, was more often disabling for everyday activities (64.1% vs. 47.3% of cases), and had more frequently led to medical consultation and sickness absence from work. It was also more often persistent when participants were followed up after a mean of 14 months (65.6% vs. 54.1% of cases). In adjusted Poisson regression analyses, non-localised LBP was differentially associated with risk factors, particularly female sex, older age and somatising tendency. There were also marked differences in the relative prevalence of localised and non-localised LBP by occupational group. CONCLUSIONS: Future epidemiological studies should distinguish where possible between pain that is limited to the low back and LBP which occurs in association with pain at other anatomical locations.

    Risk factors for chronic low back pain in adults. A case control study done in Sri Lanka
    (OMICS International, 2014) Karunanayake, A.L.
    Introduction: Not many risk factor studies for low back pain have been done in Sri Lanka. Objectives To determine the association between low back pain and posture, exercise, family history, level of education, level of income, smoking, consumption of alcohol, body mass index (BMI) and consumption of animal proteins. Methodology: A case control study was done at two main teaching hospitals in Colombo North region Sri Lanka. This study was done on adult subjects. A pretested structured interviewer administered questionnaire was used to collect data. Their weights and heights were also measured. Results: The data were collected from 530 cases and 530 controls. Their age range was 18- 90 years. Mean age (SD) for cases was 49.4 (15) years. Mean age (SD) for controls was 47.1 (17) years. Females accounted for 67% of cases and 64% of controls. Bad posture (P < 0.001), low level of physical exercise (P < 0.001), positive family history (P < 0.001), high level of income (P < 0.001), high BMI and low BMI (P = 0.001), low level of education (P = 0.013) and regular consumption of alcohol (P = 0.039) had a significant association with low back pain. Smoking and consumption of animal proteins did not have a significant association with low back pain.

    Risk factors for chronic low back pain
    (OMICS International, 2014) Karunanayake, A.L.
    Chronic low back pain that last for more than 3 months affects an estimated 15-45% of the population and is the most common cause of disability in individuals between the ages of 45 and 65 years. It has a high morbidity with high social and economic effects. The studies done all over the world show that the prevalence of chronic low back pain is increasing. However the improvements in the understanding of the pathology and management of low back pain have not improved significantly over the years. Therefore having knowledge of risk factors for low back pain will help in the prevention of development of low back pain. Therefore a review of current literature regarding the risk factors for low back pain was carried out. According to majority of studies bad posture, lack of physical exercise, presence of low back pain related genes, low levels of education and poor nutrition had a significant association with low back pain. Few studies have found a significant association between low back pain and indulging in regular smoking, regular alcohol consumption, being overweight and underweight and low socio-economic background. However some studies have failed to find a significant association between these factors and low back pain
