Background: To investigate the association between maternal country of birth and father's origin and unplanned and planned caesarean birth in Sweden. Methods: Population-based register study including all singleton births in Sweden between 1999 and 2012 (n = 1 311 885). Multinomial regression was conducted to estimate odds ratios (OR) for unplanned and planned caesarean with 95% confidence intervals for migrant compared with Swedish-born women. Analyses were stratified by parity. Results: Women from Ethiopia, India, South Korea, Chile, Thailand, Iran, and Finland had statistically significantly higher odds of experiencing unplanned (primiparous OR 1.10–2.19; multiparous OR 1.13–2.02) and planned caesarean (primiparous OR 1.18–2.25; multiparous OR 1.13–2.46). Only women from Syria, the former Yugoslavia and Germany had consistently lower risk than Swedish-born mothers (unplanned: primiparous OR 0.76–0.86; multiparous OR 0.74–0.86. Planned; primiparous OR 0.75–0.82; multiparous OR 0.60–0.94). Women from Iraq and Turkey had higher odds of an unplanned caesarean but lower odds of a planned one (among multiparous). In most cases, these results remained after adjustment for available social characteristics, maternal health factors, and pregnancy complications. Both parents being foreign-born increased the odds of unplanned and planned caesarean in primiparous and multiparous women. Conclusions: Unplanned and planned caesarean birth varied by women's country of birth, with both higher and lower rates compared with Swedish-born women, and the father's origin was also of importance. These variations were not explained by a wide range of social, health, or pregnancy factors. © 2017 John Wiley & Sons Ltd
