北京市平谷区桃农丰收期农业伤害与睡眠状况的相关性研究

Association between Sleep and Agricultural Injuries among Peach Farmers during Harvest Time in Pinggu District,Beijing

目的了解桃农农业伤害发生的情况，及其与睡眠状况之间的关联性，为我国果树业农民农业伤害的防控提供参考。方法采用随机整群抽样的方法纳入北京市平谷区山东庄镇北屯村和大北关村的所有桃农，收集一般人口统计学指标、睡眠情况、农业伤害等资料。采用多因素Logistic回归模型分析睡眠情况与农业伤害发生的关系。结果桃农的农业伤害发生率为20.8%。在控制其它变量不变的情况下，睡眠时间小于6小时和6~8小时组伤害发生的风险分别是8小时以上组的1.92倍和2.00倍，且差异均有统计学意义；经常入睡困难组伤害发生的风险是从不或偶尔组的2.09倍，P=0.001；经常半夜醒后入睡困难组伤害发生的风险是从不或偶尔组的2.00倍，P=0.007；经常白天困倦组伤害发生的风险是对照组的2.54倍，P<0.001。结论睡眠时间少和睡眠质量差是导致桃农农业伤害发生风险增加的一个因素。因此今后开展农民职业安全研究时睡眠是一个不能忽略的因素，积极改善农民的睡眠状况对农业伤害的防控具有一定的意义。

Objective In this study,we conducted a research on agricultural injury among peach framers,and examined the association between sleep and agricultural work-related injuries.This study could provide scientific evidence for establishing strategies that preventing and controlling the agricultural injury among orchard farmers in China.Methods Based on the method of randomized cluster sampling,all the peach farmers in Beitun Village and Da Beiguan Village in Shandong Town were included in our study.Information was obtained on injuries that occurred during harvest time,on socio-demographic variables,and on sleep-related variables.Logistic regression analyses were fitted separately with each sleep-related variable as the main explanatory variable,and injury as the outcome variable.Results The prevalence of agricultural work-related injuries among peach farmers was20.8%.Farmers who slept less than six hours and6to8hours per night were92%and1time more likely to be injured than those who slept more than eight hours per night.The odds ratio of injury was2.09for farmers who reported having difficulty falling asleep frequently compared with the reference group(P=0.001).Farmers who reported having difficulty falling asleep after waking at night frequently,or who experienced daytime sleepiness were at higher injury risk compared with the reference group after controlling for other injury-related risk-factors,and the odds ratio was2.00(P=0.007)and2.54(P<0.001),respectively.Conclusion Reduced sleep hours and quality may increase the risk of agricultural injuries in peach farmers after controlling for other injury-related risk factors.Future study about occupational safety for farmers needs to take into account of the sleep-related variables.Improving the sleeping quality for famers is of great importance for agricultural injury prevention.
