Gender differences in the occurrence of nonfatalagricultural injuries among farmers in Fukuoka, Japan.

Background: The lack of information regarding nonfatal agricultural injuries has been recognized as an obstacle for effective injury prevention. The aim of this study was to describe gender differences in the pattern of nonfatal agricultural injuries between the years 2008 and 2009. Methods: Farmers’ compensation injury claims were utilized to determine the mechanisms involved (machinery, non-machinery, and traffic), types of accident, sources of injury, kinds of injury, body parts affected place of injury, work being performed at the time of injury, and length of hospitalization. Agricultural injuries were identified using the International Classification of External Causes of Injury (ICECI). The Statistical Analysis System (SAS) software was used for all statistical analyses. Study variables were compared using the Mantel-Haenszel chi-square test. Results: A total of 2,729 (1,921 males) farmers’ compensation injury claims were analyzed. There were approximately 9 times as many nonfatal agricultural machinery injuries in males compared with females. The most common machinery injuries were cuts resulting from a rotary blade (31%) for males and injuries caused by being struck by a machine (24%) for females in the 65–89 years of age group. The male:female ratio of non-machinery injuries averaged 2:1 (actual numbers of 1,293 and 676, respectively), but the percentage was higher for females (83.7%) than males (67.3%). For both males and females in the 65–89 years of age group, the main source of non-machinery injuries was slopes, the main type of accident was falling/slipping, the leading kind of injury was fracture, and the main work being performed was harvesting. Female farmers had a greater risk of prolonged hospitalization (more than 30 days) compared with males (p < 0.05). Conclusions: Gender is an important factor to consider in the interpretation of nonfatal agricultural injuries. A greater number of males had machinery injuries than females; however, a higher percentage of females had non-machinery injuries than males. Further research will be needed to understand the role of differential job tasks within agriculture in explaining the difference in risk.

Pesticide exposure and subjective symptoms of cut-flower farmers

Sales of cut-flowers depend much on the outer appearance of the flowers. They are not intended to be used as foodstuffs; thus, pesticides are used more liberally for cut flower growing than for other agricultural products. Flower production is often carried out in greenhouses; therefore, pesticide exposure seems to reach not only the person spraying the pesticides, but also the non-spraying workers as well. In 2009, a special research project on pesticide poisoning, affiliated with the Japanese Association of Rural Medicine, developed a study that focused on cut-flower farmers’ exposure to pesticide, subsequent adverse symptoms experienced, and treatment modalities to relieve pesticide-related symptoms. In this group of farmers, the pesticide sprayers were almost entirely male, while the females did not do any spraying. The organophosphate metabolite level in the urine of the males was higher than that of the females. However, in the female group, a positive relation was found between average working times in the greenhouse, and urine concentration of dialkylphosphates. In 2 males of this group, the level of dimethylphosphate was detected at 1,000 times the median level. Their butyrylcholinesterase activity levels on the day of testing had declined to 64%, 72% of their average level of the proximate 4 years, respectively. Communication with these subjects regarding pesticide exposure and methods of prevention appeared to be an effective approach for reducing symptom severity. Among soil fumigants, chloropicrin and 1,3-dichloropropene were most often used. Difficulty breathing was one of the subjective symptoms associated with chloropicrin, as well as watery eyes, coughing, and runny nose. These symptoms were effectively suppressed by the preventative practice of wearing gas masks and goggles while using soil fumigants. It would be beneficial to strongly encourage use of suitable protective gear among farmers exposed to soil fumigants.
