简要总结
This study will evaluate the efficacy of an intervention to improve quality and duration of self-regulated nighttime sleep (the amount of time the child maintains a combination of uninterrupted sleep, quiet wakefulness, and re-initiation of sleep without parental intervention).
详细描述
The development of adequate sleep patterns is paramount to the optimal neurodevelopment, as well as to promote proper learning, develop memory and preserve cerebral plasticity. Factors that hinder sleep patterns can negatively influence the child's growth, neurological and motor development.
The investigators will conduct a randomized controlled trial within the 2015 Pelotas Birth Cohort. At the 3-month follow-up, children who sleep less than 13 hours per 24 hours (nighttime sleep and daytime naps) will be eligible for the study. The sample size was estimated at 276 children per arm. Nighttime self-regulated sleep duration will be evaluated at baseline (age 3 months) and at 6, 12 and 24 months using actigraphy and via a sleep diary completed by the mother. Following block randomization, mothers from the intervention group will be visited by a trained fieldworker who will deliver counseling on age-appropriate normal sleep behaviors, how to facilitate sleep onset and how to manage night awakenings.

入选标准
- •To be eligible to the trial the child will need to belong to the Pelotas 2015 Birth Cohort, to be born healthy (newborns that needed intensive care after birth and with any congenital malformations will be excluded) from a single pregnancy at gestational age 37 weeks or greater, and to sleep regularly on average less than 13 hours per 24 hours (daytime and nighttime sleep) at three months of age (as reported by the mother). The information on child sleep duration per 24 hours will be gathered during the interview with mothers from the entire cohort, by means of the answer to the questions: "How many hours does the child sleep from 7pm to 7am?" and "How many hours does the child sleep from 7am to 7pm?"as well as number and duration of daytime naps, number of wake episodes during the night and how long it takes to the child to fall sleep after a nocturnal awakening.
排除标准
- •Because the potential effect of the programmed maternal physical activity during pregnancy over the sleep duration or over the poor-sleeper-newborn answer to the sleep trial is not known, newborns to mothers that participated at the PAMELA trial will not be eligible to the sleep trial. The PAMELA (Physical Activity for Mothers Enrolled in Longitudinal Analysis) is a randomized controlled trial nested in the Pelotas 2015 birth cohort planned to assess the effect of regular exercise during pregnancy on the prevention of hypertension, pre-eclampsia and preterm birth. Eligible pregnant women between the 16th and 20th week of gestation are allocated into control group (426 women who are advised to keep their usual daily activities) or intervention group (213 women who engage in an exercise program, three sessions a week).
- •Also, because the sleep intervention will recommend a series of environmental improvements to ensure a restful sleep (no screen media, low noise and light), the intervention will be restricted to families living in households with at least one bedroom. Children in continued use of medicines that can alter the sleep architecture and/or lead to drowsiness, like anticonvulsivants, will be excluded.
研究组 & 干预措施
Intervention group
Arm: Experimental: Intervention group Field workers trained in sleep hygiene counseling will advice the mothers randomly allocated to the intervention group. The intervention will be delivered at the child household and will include information on: Normal sleep behaviors during the first year of life; ideal conditions to promote sleep onset like environmental improvements that ensure restful sleep (no screen media, low noise and light); calming naptime routines and avoiding stimulating or stressing children just before naptime; practices that promote child self-regulation of sleep, including putting infants to sleep drowsy but awake; and how to handle nighttime awakenings. A booklet with the intervention content to aid the mother in implementing the intervention will be used.
干预措施: Sleep hygiene counseling (Behavioral)
Control group
Mothers randomly allocated to the control group will be visited at home following the same schedule as the intervention group. The control group will receive a written material describing the advantages of breastfeeding over maternal and child health. No advice in relation to child sleep hygiene will be delivered to the mothers from the control group.
结局指标
主要结局
Nighttime self-regulated sleep duration at 6, 12 and 24 months of age
时间窗: Up to 24 months
Nighttime self-regulated sleep duration is the maximum amount of time the child stays asleep or awake without awakening the parents at ages 6, 12 and 24 months. This outcome will be evaluated by using the actigraphy and diary records for 5 days. The Brief Infant Sleep Questionnaire (BISQ) will be used at these three visits.
次要结局
- Validation study of the Oxford neurodevelopment assessment tool (OX-NDA)(Up to 12 months)
- Neurocognitive development at 12 and 24 months of age.(Up to 24 months)
- Linear growth between age 3-12 and 12-24 months of age(Up to 24 months)
