“…Other characteristics of the studied populations were often not described in the methodology of the papers: only 9 studies clearly described migrants' length of stay in the host country ( 24 , 27 , 31 , 32 , 37 , 39 , 41 , 43 , 48 ), most of which were long stays (five or more years) and migrants' legal status was not specified in 20 studies ( 26 – 30 , 32 – 34 , 36 , 37 , 39 , 40 , 42 – 49 ). Seven studies had a comparison group ( 29 , 30 , 33 , 35 , 36 , 40 , 45 ), most frequently the majority population (6 of 7 studies) ( 30 , 33 , 35 , 36 , 40 , 45 ). Regarding occupation sectors, most of the migrant population were considered essential workers in sectors related to healthcare (6 of 26) ( 24 , 27 , 31 , 33 , 36 , 39 ) and other essential sectors (11 of 26) ( 25 – 30 , 35 , 38 , 43 , 45 , 46 ) such as agriculture or construction.…”
