In Brazil, workers without a formal job contract represent approximately half of the labor force but there are no official statistics on occupational injuries for them. This study estimates the annual incidence of non-fatal work-related injuries for workers with and without job contracts and examines gender differences.
This is a community-based study carried out with a random cluster area sample of the residents of Salvador, a city with 2.7 million inhabitants, the capital of the state of Bahia, northeast Brazil. Individuals from 18 to 65 years of age who reported having a paid job comprise the study population (n=2907). Data were obtained in individual household interviews with questionnaires applied by trained field workers.
The overall estimated annual incidence rate (IR) was 5.6/100 full-time equivalent workers (FTE). The incidence of injuries differed between workers with informal (IR=6.2/100 FTE) and formal jobs (IR=5.1/100 FTE), and according to gender (IR=5.8/100 FTE for female and 5.5/100 FTE for male), but these differences were not statistically significant. Statistically significant positive associations between informal jobs and non-fatal work injuries were observed among women with medium education [incident rate ratio (IRR) 2.02, 95% CI 1.00-4.00] and women with black skin (IRR 1.71, 95% CI 0.99-2.97) who perceived a job as dangerous (IRR 2.00; 95% CI 1.09-3.64) or who had no occupational training (IRR 2.08; 95% CI 1.05-4.20).
This study shows that non-fatal work injuries are a common health problem among adults in urban Brazil, regardless of the type of job contract or gender, which points to a need to improve workers' health and safety programs for formal and informal hired workers.
在巴西,没有正式工作合同的工人约占劳动力的一半,但尚无关于他们职业伤害的官方统计数据。本研究估计了有工作合同和无工作合同工人非致命性工伤的年发生率,并探讨了性别差异。
这是一项基于社区的研究,对巴西东北部巴伊亚州首府萨尔瓦多市居民进行随机整群区域抽样,该市有270万居民。报告有带薪工作的18至65岁个体构成研究人群(n = 2907)。数据通过训练有素的现场工作人员使用问卷进行的个人家庭访谈获得。
总体估计年发生率(IR)为5.6/100全时当量工人(FTE)。非正式工作(IR = 6.2/100 FTE)和正式工作(IR = 5.1/100 FTE)的工人之间以及按性别(女性IR = 5.8/100 FTE,男性IR = 5.5/100 FTE)的伤害发生率存在差异,但这些差异无统计学意义。在中等教育程度的女性[发病率比(IRR)2.02,95%可信区间1.00 - 4.00]和认为工作危险(IRR 2.00;95%可信区间1.09 - 3.64)或未接受职业培训(IRR 2.08;95%可信区间1.05 - 4.20)的黑人女性中,观察到非正式工作与非致命性工伤之间存在统计学上显著的正相关。
本研究表明,在巴西城市成年人中,非致命性工伤是一个常见的健康问题,无论工作合同类型或性别如何,这表明需要改善针对正式和非正式雇佣工人的工人健康与安全计划。
