Objective Late-onset small-for-gestational-age (SGA) fetuses usually show normal uterine artery Doppler and were long considered to have a good peri- and postnatal outcome. Recently, these fetuses were identified to have a risk factor for cardiovascular disease. The aim of our study was to evaluate former SGA children concerning their cardiovascular risk and nutrition behavior at the age of 1 year. Methods We performed a prospective longitudinal cohort study at the University Hospital “Klinikum rechts der Isar” of the Technical University of Munich. Singleton pregnancies from 32 weeks with suspicion of SGA and healthy control pregnancies were included. Results A total of 100 former SGA children and 113 controls with normal weight (AGA) were examined at 1 year of age. Drop-out for 1-year follow-up was 27%. SGA children had significantly higher systolic (92.8 ± 9.8 mmHg vs. 87.5 ± 10.7 mmHg, p  = 0.001), diastolic (63.1 ± 8.5 mmHg vs. 60.0 ± 10.3 mmHg, p  = 0.028) and mean (73.0 ± 7.8 vs. 69.2 ± 9.7 mmHg, p  = 0.004) blood pressure than AGA children. Comparing two breastfeeding periods (0–4 months vs. > 7 months), a downward trend in blood pressure values for longer breastfeeding periods was shown. Conclusion Our study showed that even late-onset small-for-gestational-age fetuses seem to have cardiovascular problems, although they were previously thought to be “healthy”. Up to now, blood pressure measurement is not part of indicated health checks in former SGA or even fetal growth-restricted children which should be changed. Further studies are needed to investigate cardiovascular prevention programs in children.
