Fit für Zwei – Eine Studie zu sitzendem Verhalten und körperlicher Aktivität in der Schwangerschaft

Zusammenfassung

Hintergrund In der Pilotstudie wurde die mit sitzendem Verhalten verbrachte Zeit sowie die körperliche Aktivität bei Schwangeren mit Hilfe eines Akzelerometers erfasst.

Methoden Für die Studie wurden 32 Schwangere rekrutiert, davon elf im ersten Trimester. Definierte Tragezeiträume für das Akzelerometer waren in den Trimestern die Wochen 9–12, 23–26 bzw. 36–39. Im Anschluss an die jeweils 7-tägige Messung erfolgte eine selbstadministrierte Befragung.

Ergebnisse Die Schwangeren waren im Mittel 30 Jahre alt, 50% unter ihnen erstgebärend, 68,8% hatten Hochschulreife. Das Akzelerometer wurde im Mittel 13 Stunden pro Tag getragen. In allen Trimestern wurde mehr als die Hälfte der Zeit sitzendes Verhalten aufgezeichnet. Moderat-anstrengende Aktivität war mit einem Anteil von 4,7% im zweiten Trimester höher, verglichen mit 2,5% im ersten und 3,8% im dritten Trimester. Die Empfehlungen der Fachgesellschaften, pro Woche 150 Minuten moderat-anstrengend aktiv zu sein, erfüllten 36% im ersten, 54% im zweiten und 58% im dritten Trimester. Verglichen mit Mehrgebärenden zeigten Erstgebärende im zweiten und dritten Trimester doppelt so hohe Zeitanteile in moderat-anstrengender Aktivität.

Fazit Sitzendes Verhalten dominiert mehr als die Hälfte der tagsüber erfassten Zeit bei Schwangeren. Etwa die Hälfte erfüllt die Empfehlungen internationaler Leitlinien im zweiten und dritten Trimester. Die Ergebnisse der Studie machen deutlich, dass sitzendes Verhalten und körperliche Aktivität stärker in den Fokus von Praxis und Forschung rücken sollte, um Schwangere zu einem aktivieren Lebensstil zu motivieren.

Abstract

Background In the pilot study sedentary behavior and physical activity were measured in pregnant women using an accelerometer.

Methods A total of 32 pregnant women were enrolled in the study; eleven of them were included in the first trimester. The defined wearing periods for the accelerometer in the first, second and third trimester were weeks 9–12, 23–26, and 36–39, respectively. A self-administered survey was carried out after a 7-day measurement.

Results The pregnant women were on average 30 years old, 50% were nulliparous, and 68.8% had a high school diploma. The accelerometer was worn on average of 13 hours per day. Sedentary behavior was recorded more than half of the wearing time for all trimesters. The proportion of time spent in moderate-to-vigorous activity was highest at 4.7% in the second trimester, compared to 2.5% in the first and 3.8% in the third. A proportion of women, ranging from 32% in the first, 54% in the second, and 58% in the third trimester did reach the levels of PA recommended by the guidelines. Nulliparous women in the second and third trimester spent twice as much time in moderate-to-vigorous activities compared to multiparous women.

Conclusion Pregnant women spent more than half of the monitored day in sedentary behaviors. Half of them did meet the recommendations for physical activity in the second and third trimester. The results show that sedentary behavior and physical activity should be considered more in clinical practice and research to motivate pregnant women to adopt a physically active lifestyle.
