Substance abuse is a serious problem, because it affects both workers and young people. Prevalence and consequences of cannabis abuse among construction workers in particular are not well studied in Egypt.
To determine the association between non-fatal occupational injuries among construction workers and their demographic and occupational factors and to assess the frequency of cannabis abuse and its relationship to injury severity and workdays lost.
A case-control study was conducted at Mansoura Emergency Hospital. Cases were 100 acutely injured male workers. A control group of 90 healthy age-matched workers was selected from 8 construction sites. Workers were interviewed, and a questionnaire was completed that included socio-demographic data, full occupational history, and causes and type of injury. Injury outcome measures included lost workdays and the injury severity score (ISS). Cannabis abuse in injured workers was monitored by preliminary testing of urine and confirmatory testing of blood.
Logistic regression analysis revealed that the independent predictors of occupational injuries were rural residence, being a carpenter or painter and past history of injuries. The most common accidents were slipping falls (62%). Confirmed cannabis test was positive in 51.1% of the injured workers. Median days away from work were greater among cannabis users than non-users. The ISS was significantly higher among users compared to non-users ( p < 0.05).
Cannabis abuse can increase injury severity and prolong workdays lost. Drug testing is recommended for at-risk construction workers with inadequate safety measures.
药物滥用是一个严重问题，因为它对工人和年轻人都会产生影响。尤其是埃及，建筑工人中大麻滥用的患病率及后果尚未得到充分研究。
确定建筑工人非致命职业伤害与其人口统计学和职业因素之间的关联，并评估大麻滥用的频率及其与伤害严重程度和误工天数的关系。
在曼苏拉急救医院进行了一项病例对照研究。病例为100名急性受伤的男性工人。从8个建筑工地选取了90名年龄匹配的健康工人作为对照组。对工人进行了访谈，并完成了一份问卷，内容包括社会人口学数据、完整的职业史以及伤害的原因和类型。伤害结局指标包括误工天数和伤害严重程度评分（ISS）。通过尿液初步检测和血液确证检测来监测受伤工人中的大麻滥用情况。
逻辑回归分析显示，职业伤害的独立预测因素是农村居民、木工或油漆工以及既往受伤史。最常见的事故是滑倒（62%）。51.1%的受伤工人大麻检测呈阳性。大麻使用者的中位误工天数比非使用者更多。与非使用者相比，使用者的ISS显著更高（p < 0.05）。
大麻滥用会增加伤害严重程度并延长误工天数。建议对安全措施不足的高危建筑工人进行药物检测。
