The hypothesis that informal jobs, which imply absence of formal labour contracts, instability and the absence of fringe benefits, are positively associated with psychiatric symptoms was evaluated in a poor urban area of Brazil.
With data from a cross-sectional study, the association between informal jobs and high number of psychological symptoms was estimated. The study population was composed of 327 women randomly selected from a community in the city of Salvador, Brazil. Women who reported having a job without a formal contract were classified as informal workers. Psychological symptoms were collected through a validated questionnaire, the QMPA.
A positive association between informal work and a high number of psychological symptoms was found (crude prevalence ratio = 1.88, 95% confidence interval [CI]: 1.24-2.85). More than 4 hours of housework a day and being a family head were confounders, although adjustment for these variables did not significantly change the results (adjusted prevalence ratio = 1.97, 95% CI: 1.26-3.09).
These findings are suggestive that informal work may be a risk for mental symptoms. Reinforcement of universal labour rights coverage and improvement in housework sharing are recommended.
在巴西一个贫困城区对以下假说进行评估，即意味着没有正式劳动合同、工作不稳定且没有附加福利的非正规工作与精神症状呈正相关。
利用一项横断面研究的数据，估算非正规工作与大量心理症状之间的关联。研究人群由从巴西萨尔瓦多市一个社区随机选取的327名女性组成。报告从事无正式合同工作的女性被归类为非正规工人。通过一份经过验证的问卷QMPA收集心理症状。
发现非正规工作与大量心理症状之间存在正相关（粗患病率比=1.88，95%置信区间[CI]：1.24 - 2.85）。每天家务劳动超过4小时以及作为户主是混杂因素，尽管对这些变量进行调整并没有显著改变结果（调整患病率比=1.97，95%CI：1.26 - 3.09）。
这些发现表明非正规工作可能是精神症状的一个风险因素。建议加强普遍的劳动权利覆盖范围并改善家务分担情况。
