Epidemiology of pain in back and extremities in rural population: A community-based estimation of age- and sex-specific prevalence, distribution, duration and intensity of pain, number of painful sites and seasonality of pain during twelve months in rural Gadchiroli, India.

BACKGROUND: Population-based estimates of the burden of pain in back and extremities (PBE) by sex, age, intensity, seasonality and site are lacking from rural India. METHODS: Two villages were randomly selected from a cluster of 39 villages in Gadchiroli district in India. All residents'≥20 years of age were surveyed in January 2010 by trained surveyors by making household visits. Information on PBE in the 12 months prior to survey was obtained using a structured, pretested questionnaire. RESULTS: The 12-month period prevalence of PBE was 75% (95% confidence interval CI = 72.54-77.73) in men and 91% (95% CI = 88.66-92.13) in women. The prevalence of PBE in the participants >50 years was 94% while that in the age group 20 to 50 years was 79% (P < 0.05). The site with the highest prevalence of pain was low back (women 80%, men 59%). The mean number of painful sites per person was 5.42 (95% CI = 5.17-5.67) in women, 3.68 (95% CI = 3.45-3.90) in men, 3.89 (95% CI = 3.71-4.07) in participants aged 20 to 50 years and 6.48 (95% CI = 6.11-6.85) in those >50 years. Among participants across the age and sex groups, the prevalence of mild pain was higher than severe pain at all the anatomical sites. Among various seasons, the highest prevalence of pain was in the rainy season (14%). CONCLUSION: The prevalence and the number of painful sites were higher among women and in those >50 years of age. The public health interventions for PBE need to focus on these two high risk groups.

Burden of pain in back and extremities in rural population: A community-based estimation of 12-month prevalence, distribution and duration of pain in rural Gadchiroli, India.

BACKGROUND: Population based estimates of the burden of pain in back and extremities (PBE) are lacking from rural India. We estimated this burden, measured as a) 12-month prevalence, b) site specific prevalence c) total number of painful sites per adult, d) severity of pain and e) duration of pain in the rural adult population in Gadchiroli, India, over a period of 12 months. METHODS: This population-based, cross-sectional study was conducted in two villages randomly selected from a cluster of 7 eligible villages in Gadchiroli district of India. All adults ≥20 years in these villages were surveyed by the trained community health workers in January 2010 by making household visits. The data were collected using a structured, pretested questionnaire on the history of pain in back and extremities (PBE) at various anatomical sites and its features during the previous 12 months. RESULTS: Out of 2535 eligible adults in two villages, 2259 (89%) were interviewed, of which 1876 (83%) had an episode of PBE in the preceding 12 months. The period prevalence of pain was 76% in back (including lower back, thoracic and neck) and 71% in the extremities. Highest site specific prevalence was at lower back (70%), knee (46%), neck (44%), leg/calf (39%) and mid-back (39%). The mean number of painful sites per adult was 4.57 (standard deviation (SD) = 4.17). The prevalence of severe pain was 15%. The mean number of painful days due to PBE was 166 days. Female gender (odds ratio (OR) = 2.8, 95% confidence interval (CI) = 2.1-3.6), farming/labour occupation (OR = 1.8, 95% CI = 1.4-2.4), increasing age (more than 60 years OR = 6.3, 95% CI = 3.3-11.9) were significantly associated with the risk of PBE. CONCLUSION: Nearly five out of six adults in rural Gadchiroli suffered from pain in back or extremities during the preceding 12 months. Pain was at multiple sites and was present on a mean 166 days in the year. Female gender, farming / manual labor as occupation and increasing age were the key risk factors identified. The pain in back and extremities emerges as a public health priority in rural communities.

Activity limitation and disability due to pain in back and extremities in rural population: A community-based study during a period of twelve months in rural Gadchiroli, India.

BACKGROUND: Population based estimates of the extent of the activity limitation due to back pain and disability due to musculoskeletal pains are lacking from rural India. We estimated this burden as a) extent of activity limitation due to back pain, b) disability due to musculoskeletal pains, c) grading of the limitation of each activity due to back and musculoskeletal pain in the rural adult population in Gadchiroli, India. METHODS: This population-based, cross-sectional study was conducted in two villages randomly selected from a cluster of 7 eligible villages in Gadchiroli district of India. All adults ≥20 years in these villages were surveyed by the trained community health workers in January 2010. Disability due to back pain was evaluated using newly developed questionnaire for women and men which assessed limitations in the gender-specific daily household and occupational activities in a rural area. Disability due to pain in extremities was assessed using the Health Assessment Questionnaire (HAQ). RESULTS: The total population of the two villages was 3735 out of which 2535 (67.9%) were adults ≥20 years of age and were eligible to participate in the study. Of these, 2259 (89%) were interviewed and 1247 participants (55%) had any pain on the day of the survey. Activity limitation questionnaire was filled for 716 (91.4%) out of 783 patients with back pain. HAQ scale was filled for 524 (85.2%) out of 615 patients with pain in extremities. Among men with back pain, respectively 11%, 19%, 60% and 11% had no, mild, moderate to severe difficulty or were completely unable to perform agrarian work, while among women, respectively 6%, 20%, 69% and 4% had no, mild, moderate to severe difficulty or were completely unable to perform household activities. Based on the HAQ score, respectively 1%, 67%, 18% and 14% of the participants had no, mild, moderate to severe disability or were completely unable to perform the activities. CONCLUSIONS: This community-based study in rural Gadchiroli demonstrates significant mild to moderate disability and activity limitation, due to pain in back and extremities in a population involved in hard manual work, especially agricultural and underlines the need to address the problem through appropriate interventions. The study also employs for the first time an indigenously developed questionnaire to identify activity limitation due to back pain, and demonstrates the method as well as the questionnaire.

Clinical patterns and their prevalence among adult population with back pain: A community-based cross-sectional study in rural Gadchiroli, India.

BACKGROUND: Evaluating clinical patterns and their prevalence of back pain, a common problem in rural areas, can help develop treatment strategies to address this leading cause of disability. METHODS: We conducted a population-based study in rural Gadchiroli, India. In this, two-phase study, trained surveyors conducted a door to door survey (Phase 1) to identify individuals with pain in the back and extremities in two villages randomly selected using pre-defined criteria. Those with pain were evaluated by a team of spine surgeons and rheumatologists to diagnose clinical conditions among these patients (Phase 2). RESULTS: Of the 2535 eligible adults, 2259 (89%) were screened, 1247 (55%) reported pain in back and limb and were referred to the specialist clinic. Out of the 906 (73%) participants who attended the clinics, 783 (89%) had back/neck pain. The point prevalence of back/neck pain among adults was 49% (95% confidence interval (CI) = 49%-51%), non-specific low back pain 45% (95% CI = 43.4%-47.5%); non-specific neck pain 21% (95% CI = 18.9-22.4), radiculopathy 12 (95% CI = 10.4-13.1), myelopathy 0.4 (95% CI = 0.1-0.7) and other serious spinal disorders 0.2 (95% CI 0.048-0.45). The prevalence of non-specific back/neck pain and radiculopathy was higher among females. CONCLUSIONS: Non-specific back and neck pain are the commonest diagnoses among those with pain in the back and extremities, followed by radiculopathy. Serious disorders are rare. Given the high prevalence of non-specific back and neck pain, community health workers and physicians working in rural areas need to be trained systematically to manage these conditions.

Healthcare seeking behavior for back and joint pain in rural gadchiroli, India: a population-based cross-sectional study.

BACKGROUND: Musculoskeletal back and joint pain is common in rural agrarian communities in India. OBJECTIVES: To understand the healthcare seeking behavior for back and joint pain among adults in rural Gadchiroli, India. MATERIALS AND METHODS: A cross-sectional survey of 315 randomly selected respondents from 84 villages between 30 and 60 years of age was conducted by community health workers (CHWs) between October 2010 and January 2011. RESULTS: Among 280 respondents on whom good quality data were available, 215 (76.8%) respondents had back and/or joint pain in 6 months preceding the survey. A majority of the respondents with pain had sought care (170; 79.1%), mainly from private practitioners (116; 68.2%). Severe pain and inability to work were the reasons to seek care. Complete pain relief was considered the major indicator of an effective treatment. Injectable medications (127; 59.1%) and intravenous fluids (92; 42.8%) were considered highly effective; while about 50% were unaware of the role of physiotherapy and surgery for this problem. When asked about the preferred provider who should provide village level treatment of this problem, more than half (135; 62.8%) of the respondents chose a trained village health worker. CONCLUSIONS: A majority of the individuals with back and/or joint pain in rural Gadchiroli seek care, mainly from private practitioners. However, for the village-level treatment of this problem, respondents preferred a trained village level worker. High expectation of complete pain relief, preference for injectable medications, and low awareness about nonpharmacological modalities will be the major challenges while providing community level care for this problem.

Quality of medical training and emigration of physicians from India.

BACKGROUND: Physician 'brain drain' negatively impacts health care delivery. Interventions to address physician emigration have been constrained by lack of research on systematic factors that influence physician migration. We examined the relationship between the quality of medical training and rate of migration to the United States and the United Kingdom among Indian medical graduates (1955-2002). METHODS: We calculated the fraction of medical graduates who emigrated to the United States and the United Kingdom, based on rankings of medical colleges and universities according to three indicators of the quality of medical education (a) student choice, (b) academic publications, and (c) the availability of specialty medical training. RESULTS: Physicians from the top quintile medical colleges and of universities were 2 to 4 times more likely to emigrate to the United States and the United Kingdom than graduates from the bottom quintile colleges and universities. CONCLUSION: Graduates of institutions with better quality medical training have a greater likelihood of emigrating. Interventions designed to counter loss of physicians should focus on graduates from top quality institutions.
