Abschätzung
-
Abschätzungsart:
Gruppe
- Fragebogen: Nutzung von elektrischen Geräten
- Messung: die Teilnehmerinnen trugen das Messgerät zur 24-stündigen Messung während eines typischen Tages an der Taille und legten es neben ihr Bett während des Schlafens, Beurteilung, inwieweit ihre Aktivitäten im Messzeitraum im Vergleich zu einem normalen Tag während der Schwangerschaft typisch waren
- Berechnung: zeitgewichteter Mittelwert der 24-stündigen Messung
