Disparities in excess deaths from the COVID-19 pandemic among migrant workers in Kuwait

Abstract

Background The actual human cost of the pandemic cannot be viewed through the COVID-19 mortality rates alone, especially when the pandemic is widening the existing health disparities among different subpopulations within the same society. In Kuwait, migrant workers were already disproportionately impacted by COVID-19 and its unintended consequences. The totality of that effect on mortality is yet to be fully understood. Objective To estimate excess deaths in the pandemic year of 2020 among the Kuwaiti and non-Kuwaiti migrant populations. Methods We analyzed publicly available retrospective data in Kuwait on total annual mortality historically (from 2005 to 2019) and in 2020. We fitted a quasi-poisson generalized linear model adjusted for yearly trend and nationality to estimate the expected deaths in 2020 in the absence of the pandemic. We calculated excess deaths as the difference between observed and expected mortality for the year of the pandemic in both Kuwaitis and non-Kuwaitis. Results In the absence of the pandemic, we expected the total mortality in Kuwait to be 6629 (95% CI: 6472 to 6789) deaths. However, the observed total mortality in 2020 was 9975 deaths; about 3346 (3186 to 3503) more deaths above the expected historical trend. Deaths among migrant workers would have been approximately 71.9% (67.8 to 76.0) lower in the absence of the pandemic. On the other hand, deaths among Kuwaitis would have been 32.4% (29.3 to 35.6) lower if the country had not been hit by the pandemic. Conclusion The burden of mortality brought on by the COVID-19 pandemic is substantially higher than what the official tally might suggest. Systematically disadvantaged migrant workers shouldered a larger burden of deaths in the pandemic year. Public health interventions must consider structural and societal determinants that give rise to the health disparities seen among migrant workers.

Migrant agricultural workers’ deaths in Ontario from January 2020 to June 2021: a qualitative descriptive study

“…Migrant workers’ legal standing as temporary workers, with limited protections and entitlements under the law, also merit scrutiny as factors that contribute to this group’s marginalization, and subsequent risk of death, due to a lack of timely and independent access to services [ 98 – 100 ]. Similar conclusions have been drawn in other regions of the world as a result of increased deaths among migrant worker populations [ 101 ].…”

“…Although the specific findings and recommendations were made with the Ontario, Canada context in mind, they can be extrapolated to other jurisdictions. Structural vulnerabilities, including precarious migration and work status, familial separation, poor living and working conditions, and systemic barriers to healthcare, benefits, protections, and rights, are common experiences across many migrant worker populations internationally, collectively leading to higher risks of injury, illness, and death [ 107 – 109 ]. Therefore, adequate prevention strategies, improved healthcare access, and robust injury and death reporting, as well as inclusive methods to help surviving family members navigate bereavement entitlements, are of global relevance and should be explored further in future research.…”

Global Excess Mortality during COVID-19 Pandemic: A Systematic Review and Meta-Analysis

“…After exclusion, 439 studies were eligible for full-text review. The final meta-analysis comprised 20 eligible studies ( Figure 1 ), References [ 15 , 21 , 24 , 25 , 26 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 ] of which 79 countries were included in the study ( Table 1 ).…”

Extreme heat and work injuries in Kuwait’s hot summers

“…Migrant labourers typically work in poorer and tougher conditions than their Kuwaiti national counterparts. Migrant labourers may be more likely to lack access to cooling facilities, whether on site or at home, rendering them more vulnerable to heat exposure, especially as they may be more likely to have worse baseline health status as well 5 28–31. Careful considerations for susceptible groups, such as migrant workers, are desperately needed.…”
