Abstract

Introduction: This study analyses for the first time the Tyrolean perinatal mortality stratified by the country of origin of the mother. Data of the Tyrolean birth registry were evaluated from 20002008. The aim of our study was to analyse differences in perinatal mortality according to the country of origin of the mother. Methods: 58787 single births were assessed between the years 20002008. Mothers with similar experiences of how to access the health-care system were aggregated into 5 groups: (1) Tyrol/Austria, (2) western Europe/West, (3) former Yugoslavia/eastern Europe, (4) Turkey and (5) other countries. The odds ratio for perinatal mortality according to the country of origin of the mother was calculated in a multivariate model. The following independent variables were included: age of mother at birth, parity, housewife during pregnancy, week of gestation at the first check-up visit, smoking, preterm delivery and weight of the newborn. Results: The number of mothers of Tyrolean/Austrian origin decreased over the years by 2% whereas the number of mothers from Western Europe/West increased by 3%. The other migration groups remained constant or were slightly decreased. In the multivariate model; the perinatal mortality [odds ratio (CI)] was for the subgroups Turkey 1.06 (0.611.83) and for western Europe/West 1.09 (0.641.86), and therefore almost identical with the reference subgroup Tyrol/Austria (OR=1); the perinatal mortality was significantly increased with 2.14 (1.373.34) for the subgroup former Yugoslavia/eastern Europe and for the subgroup other countries 2.54 (1.215.36). The variables age under 18 years OR 1.99 (0.804.93) and mulitpara OR 1.30 (0.961.74) were not significantly increased. Significantly increased was preterm delivery OR 4.53 (2.807.33) and low birthweight (<1500g) OR 53.60 (32.0289.73) and 1500 to 2499g OR 4.85 (2.967.96). There are considerable differences comparing the odds ratios between the 5 subgroups for perinatal mortality. The subgroups Turkey and western Europe/West have a similar odds ratio compared to the reference group Tyrol/Austria. The subgroups former Yugoslavia and other countries have a significantly increased perinatal mortality (OR 22.5). Conclusion: The good outcome of the mothers from Turkey can be seen as similar to the Latina paradoxon, which means a better outcome of pregnancy and birth of mothers from Turkey, even though they are more comparable with other migrant groups in some risk factors, such as a lower socioeconomic standard, late check-ups, language difficulties and cultural factors. A single case analysis would be necessary to examine the exact causes. © Georg Thieme Verlag KG Stuttgart New York.
