Abstract

Objectives
The purpose of this study was to explore and evaluate the characteristics and quality of infant and maternal sleep (total sleep time, sleep efficiency, and wakefulness after sleep onset) using an actigraph.
Methods
The characteristics and quality of sleep were assessed in 22 dyads of mothers and infants aged 3–12 months. The quality of infant and mother sleep was collected using an actigraph for 12 consecutive days; this was repeated three times at 4-week intervals, and characteristics of infant sleep were measured using the Brief Infant Sleep Questionnaire-Revised.
Results
Bedsharing with infants at 7–12 months of age was higher (12.5%) than with those at 3–6 months of age (50.0%). Regarding the sleeping position, half of the infants aged 3–6 months adopted the lateral (25.0%) and prone (25.0%) positions, and the remaining half (50.0%) aged 7–12 months adopted the lateral position. It was found that 45.5% of mothers of infants used breastfeeding and pacifiers to induce sleep in infants and to help their babies go back to sleep when they woke up. The total sleep time and sleep efficiency of infants and mothers were 434.68 minutes per day and 73.1% and 379.53 minutes per day and 82.8%, respectively, indicating that both infants and mothers had low sleep quality.
Conclusions
To safeguard infants’ sleep, it is necessary to provide appropriate information and education to parents and necessary interventions for resolving sleep problems and improving the quality of sleep for both infants and mothers.
