Abstract
This study compares sleep outcome measures obtained using normal- and low-frequency extension (LFE) settings (Actilife). Forty-two children (aged 3–6 years) were instructed to wear an ActiGraph GT3X+ accelerometer on their hip for 7 days, 24 h/day. Total sleep time (min), sleep efficiency (%), and number and cumulative length (min) of awakening were used to compare the settings. Results suggest that the LFE setting results in significant but relatively small reductions in the sleep metrics of children. Trial registration no.: clincialtrials.gov (ID no. NCT02223234)
Novelty
•
LFE setting, available through ActiGraph, estimates a significantly reduced total sleep time and efficiency.
Résumé
Cette étude compare les mesures des résultats du sommeil obtenues en utilisant des réglages standards et d’extension des fréquences basses (« LFE »; Actilife). Quarante-deux enfants (3–6 ans) sont invités à porter un accéléromètre ActiGraph GT3X+ sur leur hanche pendant 7 jours, 24 h/jour. Le temps de sommeil total (min), l’efficacité du sommeil (%) et le nombre et la durée cumulée (min) du réveil sont utilisés pour comparer les réglages. Les résultats suggèrent que les réglages de LFE entraînent des réductions significatives, mais relativement faibles, des mesures du sommeil des enfants. Numéro d’enregistrement de l’essai : clinictrials.gov (numéro ID NCT02223234).
Nouveauté
•
Le réglage d’extension des basses fréquences disponible via ActiGraph estime une durée totale de sommeil et une efficacité significativement réduite.
