RESUMEN
STUDY OBJECTIVES: Growing evidence suggests concordance between parent and youth sleep. However, no known study has simultaneously examined concordance among siblings' sleep patterns. This study investigated daily and average concordance in (1) parent-youth and (2) sibling actigraphy-measured sleep, as well as the degree to which sibling concordance varied by sleeping arrangements. METHODS: 516 twin siblings (Mage = 10.74, 51% female; 30% monozygotic (MZ) twin pairs, 37% same-sex dizygotic pairs (DZ-ss), 33% opposite-sex DZ pairs (DZ-os)) and their primary caregivers (Mage = 40.59, 95% female) wore wrist-based accelerometers for 7 consecutive nights to measure sleep duration, efficiency, midpoint time, and latency. Primary caregivers also reported on demographics, youth pubertal status, and room-sharing. Two-level multilevel models were estimated to examine daily and average concordance in parent-youth and sibling sleep. RESULTS: Daily concordance was observed between parent and youth sleep duration and midpoint; average concordance was found for sleep duration, midpoint, and latency. Within sibling dyads, daily and average concordance was evident across all sleep parameters (duration, efficiency, midpoint, latency), with generally stronger concordance patterns for MZ than DZ twin pairs, and for twins who shared a room with their co-twin. CONCLUSIONS: This is the first known study to document concordance among parent-youth and siblings' actigraphy-measured sleep within the same study (i.e., triad). Our findings can help inform the development of family-level interventions targeting daily and overall sleep hygiene.

The present study of 124 families examined linkages between patterns of sleep arrangement use across the first 6 months post-partum and (a) family socio-demographics, (b) nighttime sleep of infants, mothers, and fathers, and (c) coparenting distress, and mothers' emotional availability with infants and bedtime. Families were recruited when infants were 1-month-old, and infants were classified, from video data available at 3 and 6 months post-partum, into one of three sleep arrangement pattern groups: Solitary sleep, cosleeping, and cosleeping (at 3 months)-to-solitary sleep (at 6 months). Mothers in cosleeping arrangements were more likely to be at higher socioeconomic risk, non-White, unemployed, and to have completed fewer years of education. Controlling for these variables and for duration of breast feeding and parental depressive and anxiety symptoms, subsequent 3 (sleep arrangement pattern) X 2 (infant age: 3 and 6 months) mixed-model analyses of covariance revealed that sleep arrangement patterns were more robustly linked with maternal sleep than with infant and father sleep. Mothers in cosleeping arrangements experienced more fragmented sleep and greater variability in fragmented sleep relative to mothers of infants in solitary sleep, and fathers in cosleeping arrangements showed greater variability across the week in the number of minutes of nighttime sleep. Cosleeping was associated with mother reports of less positive and more negative coparenting, and mothers in cosleeping arrangements were independently observed to be less emotionally available with their infants at bedtime compared to mothers in the other two sleep arrangement groups. These linkages were largely upheld after statistically controlling for mothers' stated preference for sleep arrangements they were using.

Objective: This study aimed to examine the sleep arrangements and soothing methods and to assess their associations with sleep problems among children aged < 3 years in China. Methods: A cross-sectional survey was conducted in 2019 from six provinces in China. A total of 1,195 caregivers of children aged 0-35 months were included in the study. Data on sleep arrangements, soothing methods, and sleep problems (i.e., frequent night awakenings and difficulty falling asleep) were assessed using the Brief Infant Sleep Questionnaire. The reasons for bed-sharing in sleep arrangements were recorded using a self-designed questionnaire. Results: The bed-sharing practice was very prevalent at any age, which ranged from 69.9% to 78.3%. Most infants fell asleep while feeding or being rocked/held before age 12 months. By age 35 months, 62.4% of the children fell asleep in bed near parents. The most common reasons for bed-sharing were breastfeeding/feeding and convenience. Parental involvement when falling asleep was significantly related with frequent night awakenings and difficulty falling asleep. No association was found between bed-sharing and sleep. Conclusion: Bed-sharing and parental involvement were very common among Chinese children aged < 3 years. Children who fall asleep with parental involvement were more likely to have sleep problems.
