“…Kothiyal and Yuen, [24]; Olendorf and Drury, [28] and Reneman et al [29] strongly pointed that forward bending and twisting posture imposes higher postural strain among the workers which might be the cause of discomfort in different body parts [23,30]. Osborne et al [31] studied on farmers and reported that lower back pain was the most common MSD among the farmers, followed by upper and then lower extremity MSDs. They also suggested that the prevalence of MSDs in farmers was greater than in non-farmer populations.…”

Abstract:Background: Industrial noise is usually considered mainly from the point of view of environmental health and safety, rather than nuisance, as sustained exposure can cause permanent hearing damage. Objective: To assess the Noise induced hearing loss in steel factory workers. Methods: It was a cross sectional study done to evaluate the hearing status of factory workers, working nearby a rural hospital, which were then correlated with the duration of work and SPL (in dBA) of exposure at their workplace. Results: In this study, Noise Induced Hearing Loss (NIHL) was calculated in the workers by taking the average of the 4 frequencies i.e. 500Hz, 1000Hz, 2000Hz and 4000Hz in right and left ear separately. Results showed that 129 (37.83%) workers were having Mild SNHL in Right ear i.e. between 26-40 dB. 203 (59.54%) of the workers were having normal hearing i.e. hearing loss not exceeding 25 dB. Only 9 (2.63%) workers had moderate (41-60 dB) hearing loss in right ears. Whereas in case of left ears results showed that 145 (42.52%) workers were having Mild SNHL in left ear i.e. between 26-40 dB. 185 (54.25%) of the workers were having normal hearing i.e. hearing loss not exceeding 25 dB. Only 11 (3.23%) workers had moderate (41-60 dB) hearing loss. Conclusion: Duration of exposure of individuals was found in the range from 6 years to 20 years. Maximum number of workers i.e. 235 (68.92%) were exposed to a time duration of 16 to 20 years followed by 96 (28.15%) who were exposed to 11-15 years. There were 10 (2.93) workers who were having the exposure of 6 to 10 years.

“…There is consequently excess load on the musculoskeletal system of farmers, particularly in the lumbar region. One review paper focusing on farmers with musculoskeletal symptoms reported that the prevalence of low back pain is higher in these subjects than in nonagricultural workers 7) . The European Directive on Mechanical Vibration set down requirements for WBV in the form of a daily exposure action value 8) (EUEAV) in 2006.…”

A field study of exposure to whole-body vibration due to agricultural machines in a full-time rice farmer over one year: Hiroji TSUJIMURA, et al. Division of Occupational and Environmental Health, Department of Social Medicine, Shiga University of Medical Science-Objectives: The aims of this study were to clarify in detail the levels of whole-body vibration (WBV) exposure from a variety of agricultural machines in a rice farmer over one year, and to evaluate the daily level of exposure compared with European and Japanese threshold limits. Methods: The subject was a full-time, male rice farmer. We measured vibration accelerations on the seat pan and at the seat base of four tractors with various implements attached, one rice-planting machine, two combine harvesters, produced by the same manufacturer, and one truck used for transportation of agricultural machines. The position and velocity of the machines were recorded in parallel with WBV measurements. In addition, during the year starting in April 2010, the subject completed a questionnaire regarding his work (date, place, content, hours worked, machines used). We calculated the daily exposure to WBV, A(8), on all the days on which the subject used the agricultural machines. Results: The WBV magnitude in farm fields was relatively high during tasks with high velocity and heavy mechanical load on the machine, and had no dominant axis. The subject worked for 159 days using the agricultural machines during the year, and the proportion of days on which A(8) values exceeded the thresholds was 90% for the Japan occupational exposure limit and 24% for the EU exposure action value. Conclusions: Our findings emphasize the need for rice farmers to have health management strategies suited to the farming seasons and measures to reduce WBV exposure during each farm task.

“…Because clinical approaches exist for blocking IL-6 [45,46], future studies could investigate the role of IL-6 in modulating bone deterioration induced by chronic airway inflammatory agents. Our studies are focused on the lungbone axis because of the high prevalence of bone and airway disease in agricultural workers [9][10][11]. However, these data might have broader implications for understanding adverse systemic manifestations (e.g.…”

“…Approximately two-thirds of agriculture workers develop respiratory diseases (e.g. rhinosinusitis, asthma, chronic bronchitis, COPD) [6][7][8][9], and nearly 90% suffer from musculoskeletal disease, including high fracture rates [10][11][12]. Recently, we established an animal model demonstrating that intranasal inhalation of organic dust extract (ODE) collected from large animal (swine) confinement facilities and its microbial components induce systemic bone loss [13].…”

Agriculture workers have increased rates of airway and skeletal disease. Inhalant exposure to agricultural organic dust extract (ODE) induces bone deterioration in mice; yet, mechanisms underlying lung-bone crosstalk remain unclear. Because Toll-like receptor 2 (TLR2) and TLR4 are important in mediating the airway consequences of ODE, this study investigated their role in regulating bone responses. First, swine facility ODE stimulated wild-type (WT) bone marrow macrophages to form osteoclasts, and this finding was inhibited in TLR4 knock-out (KO), but not TLR2 KO cells. Next, using an established intranasal inhalation exposure model, WT, TLR2 KO and TLR4 KO mice were treated daily with ODE or saline for 3 weeks. ODE-induced airway neutrophil influx and cytokine/chemokine release were similarly reduced in TLR2 and TLR4 KO animals as compared to WT mice. Utilizing micro-computed tomography (CT), analysis of tibia showed loss of bone mineral density, volume and deterioration of bone micro-architecture and mechanical strength induced by ODE in WT mice were significantly reduced in TLR4 but not TLR2 KO animals. Bone marrow osteoclast precursor cell populations were analyzed by flow cytometry from exposed animals. In WT animals, exposure to inhalant ODE increased osteoclast precursor cell populations as compared to saline, an effect that was reduced in TLR4 but not TLR2 KO mice. These results show that TLR2 and TLR4 pathways mediate ODE-induced airway inflammation, but bone deterioration consequences following inhalant ODE treatment is strongly dependent upon TLR4. Thus, the TLR4 signaling pathway appears critical in regulating the lung-bone inflammatory axis to microbial component-enriched organic dust exposures.
