immigrant), reason for migration (refugee, work, family reunification, and other), length of stay in Norway (up to 2 years and longer than 2 years), municipal centrality (urban or rural), civil status (married, unmarried, and other -- including widowed, divorced, separated, and others), education level (none, low: lower secondary school, middle: upper secondary school, and high: university/college), and personal annual income in Norwegian Kroners (NOK) (low: below 200 000 NOK, medium, and high: over 400 000 NOK). Immigrant's country of origin was categorized by regions as follows: (i) Nordic countries, (ii) North America and Western Europe, (iii) Eastern Europe, (iv) Asia, (v) Africa, and (vi) South and Central America. As preliminary analyses showed similar results for Nordic countries and Western Europe/North America and for comparison with other studies, we regrouped theseregression analyses for immigrant women by region of origin. The associations between screening and socioeconomic variables were in the same direction as for the population as a whole in terms of income and living in rural areas, but differed slightly for the various immigrant groups for other characteristics. Younger age was associated significantly with Pap smear for women from Eastern Europe and the age pattern seemed to be different for women from Asia, where women aged 41--55 years took the test significantly more often. The effect of length of stay in Norway on screening varied with the immigrant group, being positively associated for women from Eastern Europe, whereas most other groups had significantly lower attendance after 2 years. Being single was positively associated for women from Eastern Europe,
