“…In order to overcome the inconclusive results with respect to inequalities in HCSU and to follow the obstacles of differences in different needs and barriers with respect to health care among migrants and non-migrants in Germany, a study with a large nationally representative sample of persons with and without migration background is needed in order to be able to make a generally valid statement about the health care situation of migrants in Germany. However, earlier studies on the utilization of doctors and hospitalization of persons with and without migration background in Germany were based on regional samples [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ], samples of children and adolescents or elderly [ 16 , 22 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ], samples of women [ 18 , 19 , 20 , 21 , 24 , 25 , 26 , 27 ], or only samples on specific medical conditions [ 5 , 29 , 34 , 36 , 37 ]. Merely a study from 2011 by Glaesmer et al [ 12 ] used a representative population survey of persons with direct and indirect migration background as well as those without to investigate differences in HCSU in Germany.…”
