In this study, labour status was based on self-reported current economic status with five mutually exclusive categories: full-time employment (>32 h/week), part-time employment (<32 h/week), unemployment, disability pension, and homemaker. The ethnic background of the respondent was based on the country of origin of the mother. In case the mother was born in The

Netherlands, the country of birth of the father was leading (CBS 2003). Different ethnic groups were defined, based on differences in experiences of migration (refugees or labour migrants) and differences in geographical and cultural distance from the Netherlands. Three ethnic minority groups were defined: (1) Turks and Moroccans, (2) Antilleans and Surinamese, and selleck chemicals llc (3) refugees. Turks and Moroccans initially came as labour Eltanexor datasheet migrants to the Netherlands from the early 1960s, while the migration of Surinamese and Antilleans/Arubans is related to the colonial past. Refugees are another important group of migrants from designated countries such as Afghanistan, Algeria, Angola, Bosnia, China, Chile, Croatia, Democratic Republic of the Congo, Eritrea, Hong Kong, Iran, Iraq, Kosovo, Liberia, Nigeria, Sudan, Serve, Sierra Leone, Somalia, South Korea, Syria and former Yugoslavia. Immigrants from other countries were not included in the analysis (n = 296). Subjects were divided into three

groups according to their highest level of educational attainment. A high educational level CHIR-99021 molecular weight was defined as higher vocational training or university; an intermediate educational level was defined as higher secondary schooling or intermediate vocational training, and a low educational level was defined as no education, primary school,

lower and intermediate secondary schooling or lower vocational training. Marital status was used to distinguish those subjects married or living together with Smad inhibitor others. Health measures Self-reported health (SRH) was measured by asking subjects to rate their overall health on a 5-point scale, ranging from ‘excellent’, ‘very good’, ‘good’ and ‘fair’ to ‘poor’. Those reporting less than ‘good health’ were defined as having a poor health (Fayers and Sprangers 2002). Health was also measured with the Dutch version of the Short Form 36 Health Survey (SF-36) (Ware and Sherbourne 1992). The SF-36 consists of 36 items that were used to calculate scores on eight dimensions: physical functioning, general health, mental health, bodily pain, social functioning, vitality, role limitation due to emotional health problems, and role limitation due to physical health problems. Scores could range from 0 to 100, with a higher score indicating a better health related quality of life. Statistical analysis Characteristics of subjects were analysed using descriptive statistics.
