Musculoskeletal disorder (MSD) among agricultural workers.

Farming is a large and main industry in Bangladesh. Large numbers of people are directly involved in farming and have very unique exposure compare to other sectors. Musculoskeletal problems among farmer population are not infrequent. This study was carried out among 200 farmers in one selected district. The study revealed that musculoskeletal problems were common among the farmers working in a traditional way. All the respondents were male. The age of all respondents lie between 20-60 years. Among them 22.5% farmers were illiterate, about 45.5% below Class V. About half (42%) of the respondents had reported pain in different parts of the body at least one or more times during working in land. And about two third (65.5%) of the farmers had history of joint pain and stiffness in last 12 month. Most of the farmers who suffered from musculoskeletal symptoms were 41-60 years. Specially who worked more then 20 years (82.6%) and average 6 hours per day (66.7%). The occurrence of musculoskeletal problems in various part of the body included Knee pain - 48.1%, Back pain (back ache) - 22.9%, Waist pain (low back ache) - 13.3%, Neck pain - 18.3% and shoulder pain - 10.7%. Length of work in year and daily average working hours were found significant association with musculoskeletal pain. It was found that musculoskeletal pain were more common among the farmers when they worked in squatting position (52%) and specially during weeding of plants (31%). Among them only 22% also engaged in other business. Most of the farmers complained dull aching pain (40.6%), only 2.3% noticed severe acute pain, but about 86% farmers' temporary stop their work for pain and 80% get relief after discontinue of work. About 75% respondents visited doctors for their pain which was statistically significant (p=0.001). It was found that the rates of musculoskeletal complaints are more among those individuals who worked relatively bad ergonomic condition, such as body position probably play an important role.

Status of blood pressure among individuals consuming saline water.

Climate change is taking its toll in the form of saline water intrusion into the mainland of Bangladesh, which is one of the lowest-altitude countries in the world. The study was carried out with the objective to assess the blood pressure status associated with salinity in saline prone selected areas of Bagherhat and Tangail districts from March 2008 - June 2008 of rural Bangladesh. Two hundred and ninety subjects were selected purposively from both the districts. About 70% of the respondents were males and below forty years of age. More than two thirds of the respondents were illiterate; belong to 4-5 member family, with monthly family income of less than Tk. 4000 per month. Only one third of the respondents were smokers. More than two thirds of the respondents from salinity area had salinity level of 2-3%. Among them majority were drinking saline water for 6-10 years and 26% were drinking for more than ten years. About 20% of the non saline respondents' systolic blood pressure was 110-120 mm of Hg and 26% of saline area had systolic blood pressure >135-140 mm of Hg. Mean systolic BP among salinity area was more than that for non salinity area. About 19% of the non saline respondents' diastolic blood pressure was ≤ 85 mm of Hg. About one third had ≥ 90 mm of Hg, among them 31% were from saline area. Mean diastolic BP among salinity area was more than non salinity area. There was no history of heart disease, and less than 1% was diabetic among them. About two thirds had mean arterial pressure <70 mm of Hg, among them majority were from non saline area. About one third had >70 mm of Hg, among them majority were from saline area. The study concluded that systolic and diastolic blood pressures of saline group were significantly higher than that of the non saline group.
