Zusammenfassung
Fragestellung: Die Prävalenz des intrauterinen Fruchttodes (IUFT) sowie die diesbezüglichen Risikofaktoren
für präkonzeptionelle Diabetikerinnen, Gestationsdiabetikerinnen und Schwangerschaften
ohne diagnostizierten Diabetes wurden vergleichend untersucht. Methode: Die Daten der Perinatalerhebung Niedersachsen für die Jahre 1987 bis 1999 wurden
retrospektiv für Schwangere mit präkonzeptionellem Diabetes mellitus (PDM: n = 3351),
Gestationsdiabetes (GDM: n = 3954) und Schwangerschaften ohne Diabetes (KDM: n = 887
779) analysiert. Ergebnisse: Intrauteriner Fruchttod: PDM n = 46 (1,35 %), GDM n = 32 (0,79 %), KDM n = 2756 (0,31
%); Odds Ratio (OR) und 95 %-Konfidenzintervall für PDM vs. KDM 4,468 (3,332 - 5,992;
p<0,01), OR für GDM vs. KDM 2,595 (1,829 - 3,682; p<0,01). Zeitpunkt des Todes vor
der 32. SSW: PDM 13,0 %, GDM 12,5 %, KDM 27,7 %, (p<0,05 für PDM vs. KDM); Zeitpunkt
des Todes zwischen der 32. und 36. SSW: PDM 37,0 %, GDM 43,75 %, KDM 33,0 %; Zeitpunkt
des Todes > 36. SSW: PDM 50,0 %, GDM 43,75 %, KDM 39,3 % (p<0,05 für PDM vs. KDM).
Anteil der verstorbenen Kinder < 10. Gewichtsperzentile: PDM 15,2 %, GDM 6,3 %, KDM
28,7 %; Anteil verstorbener Kinder > 90. Gewichtsperzentile: PDM 41,3 %; GDM 37,5
%; KDM 8,7 % (p<0,01 jeweils für PDM bzw. GDM vs. KDM). Schlussfolgerung: Das Risiko des intrauterinen Fruchttodes ist in diabetischen Schwangerschaften weiterhin
erhöht. Dieses gilt insbesondere für hypertrophe Kinder, während in nichtdiabetischen
Schwangerschaften die hypotrophen Kinder gefährdeter sind.
Abstract
Object: The prevalence of intrauterine fetal death as well as the relevant risk factors in
pregnancies of women with preconceptional and gestational diabetes mellitus and non-diabetic
women were investigated. Methods: The data of the Perinatal Registry of Lower Saxony between 1987 and 1999 for pregnancies
of women with preconceptional diabetes mellitus (PDM, n = 3351), gestational diabetes
mellitus (GDM, n = 3954) and women without diabetes mellitus (non-diabetic pregnancies,
NDM, n = 887,779) were retrospectively analysed. Results: Intrauterine fetal death occurred in 46 women with PDM (1.35 %), 32 women with GDM
(0.79 %) and 2756 non-diabetic women (0.31 %). The odds ratio (OR, 95 % CI) for PDM
vs. NDM was 4.468 (3.332 - 5.992; p < 0.01) and for GDM vs. NDM it was 2.595 (1.829
- 3.682; p < 0.01). The percentage of death, which occurs before the 32nd week of gestation, was 13 % in pregnancies with PDM, 12.5 % in pregnancies with GDM
and 27.7 % in non-diabetic pregnancies. 50 % of fetal deaths in the PDM group, 43.8
% of those in the GDM group and 39.3 % of those in the NDM group occurred after the
36th week of gestation. The percentages of dead fetuses who were under the 10th percentile of growth (small for gestational age, SGA), in pregnancies with PDM, GDM
and NDM were 15.2 %, 6.3 %, and 28.7 %, respectively. The percentages of dead fetuses
above the 90th percentile of growth (large for gestational age, LGA) were 41.3 % (PDM), 37.5 % (GDM),
and 8.7 % (NDM), (p < 0.01 for PDM vs. NDM and for GDM vs. NDM). Conclusion: The risk of intrauterine fetal death in pregnancies of diabetic women is still increased.
It seems that especially the LGA fetuses of diabetic mothers and SGA fetuses of non-diabetic
mothers are at greater risk of intrauterine death.
